Hi Matt,
FYI: here's some background on the old Wright Chemical site in the Wilmington region, in preparation for our
conference call tomorrow at 1:00.
I think the point of the call is to help WIRO determine what next actions to take with the three current permittees on
this old site, Momentive, Sitar, and Oak Bark.

Subject: FW: Wright, Hexion, Momentive, Oak Bark, Silar phone call next week
Hi Karen,
Here's the briefest summary of the site circumstances, working forward in time:
1. WIRO had a bad environmental citizen in Wright Chemical for many years. They were not able to accomplish
much with this stormwater permittee. The site has one or more SWMUs or similar buried treasures (I'm not
sure of the exact regulatory authority/program that pertains to them.)
The receiving water is grossly polluted, but not just from Wright. Upstream facilities also are suspected of
impacting the tidal creek.
3. The facility made an industrial intermediate, hexamine. Hexamine is not particularly nasty in itself, as far as we
know, but it is produced from nitrogen -containing feedstocks. Facility housekeeping was poor per my
observations in the past, and it was clear that site management was not motivated or was not competent to
effectively manage their polluted discharges.
4. More recently: Wright Chemical became Hexion; other ownership/name changes subsequently occurred, and
the current configuration of the site includes three independent (as far as we know) companies, Silar (Brian),
Momentive (Ken), and Oak Bark (Bethany). To a problematic degree, the three companies have intertwining
ownership boundaries on the site, and the path of stormwater runoff does not respect the company boundaries.
I think the three companies make related industrial chemicals, including hexamine still. Maybe intermediates
for the intermediate, but I really don't know the full details.
5. SPU rescinded the Wright Chemical permit, and eventually issued three individual, and identical, stormwater
permits in October 2010. The three permits all test for the same pollutants, and all have the same tiered
structure for responses to benchmark exceedances.
6. In SPU Ken, Bethany, Jennifer, Brian, Ken again, Bethany again, have over the years all touched the
permit/permits for this site. In the past, progress on effective permitting has been difficult for us, too.
(Bethany's participation was interrupted by the inconvenient timing of childbirth on two occasions. I also have a
really good excuse, but perhaps not as good as hers.) Now however, it looks like we have the tools in place to
accomplish something at this site(s).
7. I think the point of the current interest up here is to see how we can help Linda Willis get something
accomplished on the ground with these three pe.rmittees_
The email immediately below is a summary of the monitoring results for one of the three new permittees, Momentive.
I'm not sure about performance at the other two sites, but my impression is that Momentive is the worst.

Subject: Wright, Hexion, Momentive, Oak Bark, 5ilar phone call next week
All,
Sorry, I will be out of town on another site when you all will be conferring by phone, next Tuesday.
As far as the Momentive site, and how it may figure into your enforcement/compliance discussions, I've done a quick
review of the Momentive monitoring data wrt possible enforcement actions or Tier 3 responses:
• It appears that sampling data from Outfall 008 are missing entirely. There are data from 003, 004, 006, and 009,
but none from 008. I'll look more thoroughly in the file to see if we/WIRO granted representative outfall status,
but I don't see it now glancing through the file. The failure to sample would be a violation of the permit.
• Out of six monitoring events reported:
o #003 had 6 exceedances for NH3, Cu, Zn; 5 exceedances for TKN; 4 exceedances on formaldehyde; and
failed the tox test.
o #004 had 6 exceedances for Cu, Zn, and formaldehyde; 5 exceedances for BOD, COD, and TKN; and
failed the tox test.
o #006 had 4 exceedances on formaldehyde; and failed the tox test.
o #009 had 5 exceedances on Cu and Zn. (and PASSED the tax test)
• This performance moves us well into Tier 3 for all 5 identified outfalls at Momentive (4 exceedances during the
term of the permit for 4 of the outfalls, and failure to sample the fifth outfall), where we are enabled by the text
of the permit to direct or require remedial measures, among other options open to us.
1 would de-emphasize the performance on metals as a basis for DWQ action/direction. If we get the other stuff,
metals may very well be removed along with them; and in particular, we have the issue that in some areas of
the state Cu and Zn may be naturally in the soils and may be difficult to assign to the industrial activity with
certainty. Unless we mount some sort of testing program just for metals.
• 1 would emphasize the performance on nitrogen species and formaldehyde (also nitrogen -containing) as our
basis for action and for considering solutions. Also, it may be that the tox results are associated with ammonia
exceedances in part.
• Apart from nitrogen species and formaldehyde, Outfall 004 also shows continuing discharges of BOD and COD in
excess of benchmarks. Outfall #004 might be considered as our first target on the Momentive site for DWQ-
directed BMPs. Outfall 004 is the worst one on the Momentive site, with #003 a close second.
• On the other hand, Outfall 009 passed the tox test, and only shows continuing exceedances for Cu and Zn, which
offer us a potential problem in interpretation and as a basis for action, I think.
• For the Momentive site, if we wanted to encourage a phased in approach, we might consider our first three
steps as:
o First, target #004 and #003 for two directed BMPs; based on Momentive's performance, DWQ has the
authority in the permit to direct the installation of BMPs;
o And as a concurrent second step, Momentive must begin sampling the missing outfall #008;

11.
o And third, follow up actions with #006 and #009, perhaps with some flexibility wrt the facility's costs or
partial responses.
I think we are well past the time with #004 and #003 for'management practices' responses. These folks need to
install structural BMPs, I think.

Subject: RE: Momentive 1 Silar! Oak Bark update, meeting and site visit
Hi ten,
I'm looking into if we have received this data, but I don't think we have. I will let you know
I haven't thoroughly looked at the data yet, but regarding what the numbers mean...
>100% is good. It means at 100% stormwater, there was no significant mortality and no acute toxicity. So, the
stormwater does not need any dilution to ameliorate toxicity.
Anything less than 100% fails the benchmark endpoint. However, the permit was written to provide flexibility so that
the SPU can name another benchmark endpoint depending on the site conditions(how much dilution the stormwater
runoff might be having). For instance, on the 4/5/2011 data for Silar, outfall 001, Silar Whse, has a LC50=75.21%. This
means it is predicted that 50% of the test organisms would die at 75.2% stormwater effluent concentration. Silane Weir,
outfall 005, had a LC50=42%. This predicts that 50% of the test organisms would die at 42% effluent. So, the lower
number is worse in that a lower concentr n of stormwater will cause 50% mortality of the test organisms.
The flexibility was written in the permit to name another benchmark endpoint to account for site conditions. For
instance, if outfall 001 is a small amount of water going into a large amount of surface water and might be diluted to _
10%, then it would not be expected to cause toxicity.
will look over the data and get back with you next week.

Oh wait — I just spoke to Matt Matthews because I saw him heating up his lunch. He said the lower the worse — so is
anything less than 100% meant that it is failing?
In that case — maybe the formaldehyde and the other things do correlate with the worse acute toxicity results_
Linda — while you are talking to Momentive/Silar — can you also ask them if they have submitted their data to our lab as
required by the permit, and can you ask Momentive to submit their paperwork and results from the lab?

Hi Carol,
Well it looks like we have the first of our acute toxicity data in from the first of our sites. I was wondering if you could
take a look at it? I've attached the permit with the acute toxicity wording wording.
They should have sent you a copy of their data — and us. However we did not receive it on the proper form. Did you
receive any data? It looks like the results from one of Momentive outfall's were >100% (not sure what that means? —
everything died that even looked at it?). I believe Silar also had a 100% result from one outfall.
I have attached the data we received. If you have time to loo it, that would be great. Interestingly, some of the
highest formaldehyde, Cu, Zn, Hexamine, BOD and COD num Wrs n't correlate with the highest acute toxicity
numbers (at Momentive). �J U
Thanks Carol! Give me a call if you need/want to discuss anything here.

Subject: Momentive / Silar / Oak Bark update, meeting and site visit
Hi all,
Just wanted to send you an update on our phone meeting re: Momentive / Sitar/ Oak Bark.
Linda and I talked about a couple things we need to do:
1. Have an internal meeting.
a. We need to look at the data_ Discuss.
b. Where the topography/sw outf ails are going. Discuss.
c. Discuss Silar's proposal that they: "subtract" Momentive's SW results from theirs to get a proper result
(see a and b above)
i. Is this an issue for Oak Bark and Mometive as well? Do they want to do the same thing?
d. Come to an agreement about the permitting strategy we want to take before we go there so we have a
unified and a reed-u on strategy.
i. As part of that: talk about how we are going to let them determine where to sample
ii_ As part of that: talk about our strategy regarding acute toxicity — I'll forward the results to Carol
Hoilencamp in the lab for her to review before our meeting.
2. We need to do a site visit - to talk to them and see what the issues are. Linda will do an inspection of all 3
facilities at this time.
3. Data: I thought we didn't have any data from them, but it turns out we did in central files. I've attached them
here.
Linda suggested previously she was available on the 22rd and 23`d, perhaps we can meeting internally then. Linda
indicated she'd like to meet in the first half of Dec to go to the sites.
haven't had a chance to look at Silar's and Oak Barks data — but we can discuss at the internal meeting. Momentive's
data shows a regular exceedence of TSS, BOD, COD, NH3-N, TKN, NO3/NO2-N, Formaldehyde, Total Copper, Total Zinc,
and a pretty significant acute toxicity effect.

i
Questions I_have about M_omentive's data are:
1) What should we do about acute toxicity results. We need to get some lab input and discuss further.
2) They have not completely sampled —
a. No data for outfall 008
b. No data for 3`a quarter of this year.
c. Linda can you address these with Momentive please?
3) We need to have a complete topographical site plan for each permit file. Linda, would you mind asking for
that as well?
OK — well — if you ail can also take a look at the Oak Bark and Silar data, that would be great. I think we need to review
and compare from each outfall as compared to the topographical map, I can also do that unless we all want to do that
and talk about it in our meeting. That might be the most effective if we take a look at it first before our meeting.
If the 22"d and 23d work for you all I'll propose a meeting.
Thanks,
Jen

Gentlemen,
We're trying to get our hands around the stormwater issues on site there for the old "Wright
Chemical" facility. . which involves all three of your facility's areas. Would you all
please forward to me a copy of your stormwater DMRs (analytical results) and any analyses
from toxicity monitoring. We need everything you have as of last year and this year.
Thanks. We'll review the data and be in touch concerning a meeting to discuss the stormwater
issues. We'd like all parties to be present so that their concerns /opinions can be
considered.

Linda,
I am attaching the DMR's for the first three quarters of 2011 as well as a copy of the
benchmarks.
Answers to your questions:
1. Momentive personnel are still performing the sampling for
us. They pull both of our company's samples during the same event,
send them off for testing, -and send me the results for Silar. This
will continue with the new shared services agreement that starts
12/1/2011.
2. They are using their outfall SW003 as the "up -stream" sample.
This is probably a good representation of the water quality that
flows to our outfalls.
3. Since we are downhill from both the Momentive and Oak -Bark
operations, the impact is along the entire line.
Thanks for your help.

Subject: RE: Permit question
Peter,
I know you have always had concerns about the discharges of contaminated stormwater onto your
portion of the facility from Momentive's industrial activities. We said we would cross that
bridge when we get there, so it looks like we're there.
A couple questions.
1. Where and how are you taking the upstream samples? Are you
using Momentive's stormwater monitoring data? Are you all monitoring
during the same storm events (are the samples collected on the same
day)? We want to be comparing apples and apples.
2. Are there outfalls from the areas on Momentive's site that
are contributing stormwater pollution to Silar's property? The
reason I ask is that we would need to know what the quality of the
discharge is to the receiving stream if the first opportunity to
sample the discharge is at one of your outfalls.
3. Is there a specific area that is an issue for your site, or
is it along the entire property line between Silar and Momentive?
How many outfalls are they impacting at this point (in your
estimation)?
Once we get some details, I visit with our central office staff and see if we can figure out
how to advise you.
I'll be in touch.
Linda

Hi Linda.
Momentive informed me that due to the fact that they have exceeded benchmarks
three quarters in a row, that they will start monthly monitoring. Before Silar does the same,
I wanted to confirm that we have not exceeded the benchmarks based on subtracting the levels
from the up -gradient samples from our outfall sample results (except for the two benchmarks
noted in the most recent DMR submittal). Please let me know.

owners. Now this permit (the oldest ##) is linked to Hexion Specialty Chemicals, Inc.
o Outfalls and responsibilities and permits need to be defined for each company.
• Hexion's outfalls are listed as 003, 004, 006, 008, and 009 in their Nov. 7, 2008 application.

'� • Addition of Acute Toxicity to permit due to many repeated and egregious benchmark exceedences. See
attached Rational for Acute Toxicity use. NC DWQ believes acute toxicity may be a useful parameter in
cases where:
o ' .DWQ cannot feasibly include all test parameters in a permit or ask the permittee to test specific
chemicals stored on site (because of financial concerns, large numbers of parameters, or other
concerns};•even if we know what all the chemicals are;
o 15WQ may no't have benchmarks available for all parameters that may be discharged from the site;
o DWQ may not be able to predict environmental effects from mixed chemicals or chemicals
- produced by reactions when mixed that may be discharged from the site;
o DWQ may riot be able to know all chemicals that may be discharged from the site or these
chemicals, or information about them, may be proprietary in nature;
o DWQ may be concerned that the toxicity of some parameters (such as copper or other metals)
may be difficult to predict due to variable environmental influences such as hardness, pH, etc. '
Description of Onsite Activities:
• Hexion Specialty Chemicals, Inc. manufactures formaldehyde by reacting acetone and methanol in an
- aqueous process. Hexion then processes the formaldehyde and anhydrous ammonia to produce
hexamine and specialty Kenton resin products. Hexamine production is classified by SIC code 2869 —
regdlated under 40 CFR part 414, Subpart H — Specialty Organic Chemicals. Hexion also produces
formaldehyde derivatives.
• It is a privately owned organic chemical manufacturing plant utilizing a biotrol WWTP to treat
industrial WW. The WW treatment system utilized holding tanks, ion exchange units, bioreactors,
clarifiers, bag filters and discharge tanks.
• The facility currently operates under 3 r (2 ww for each facilityand 1 sw) originally issued to
Y` Wright Corp. whichVspbecome/seParate facilities - Oak Bark.an exion. Currently Hexion takes
responsibiltity for all SW discharges although some SW originates on Oak -Bark Property— (necessitating
the need for sw outfalls as SW leaves Oak -Bark Property). At this writing, Stormwater permits are being
�"r=dted for each of the 3 facilities and issued concurrently.

2. General Observations:
• Analytical Monitoring is regularly high. Average values for BOD= 145, COD=724, TSS=69 (but
regularly exceeding benchmark), NH3=323 mg/l, TKN=183, not-no3=22. FOR parameters COD, BOD, TSS,
NH3 and TKN there were more exceedences than non-exceedences.
• Hexion's permitted stormwater outfalls are now SW Outfall 003, 004, 006, 008 & 009 +�
• Monitoring must remain quarterly.
• Site is split up. Hexion must sample all of their outfalls — no representative outfalls status
recommended. V
• Appears that from RO's comments and recent sampling there has not been much response to
exceeded cut-off concentrations.
• EPA form 2F lists: 3
o Formaideh_ yde, Molybdenum, Aniline and Vanadium pentoxide as chemicals currently use.
TRI lists Toluene
• No monitoring or benchmarks required in EPA 2008 MSGP for this activity.

3.. Impairment: Aquatic life is impaired in Livingston Creek (Eroadwater Lake) for Turbidity.
4. Threatened and Endangered: No threatened or endangered aquatic animals are near the"Iwxion facility.
5. Location:
• Site split up from one owner - Wright Chemical - into 3 owners and changed name. Now this permit
(the oldest #) is linked to Hexion Specialty Chemicals, Inc.
• Outfalls and responsibilities need to be defined for each company.
6. Industrial Changes Since Previous Permit: Site and outfalls split up --see above notes. Constructed additional
cooling tower, new hexamine warehouse, and milling operation building. Also new pharmaceutical production
building and new storage tanks.
7. Analytical Monitoring Notes: See General observations and monitoring spreadsheet below.
8. Qualitative Monitoring Notes: Permittee sent in monitoring data. Color varied. Some solids decrease.

2. Permits need to be issues at the same time so that all outfalls are covered by a permit.
Revised Permit Recommendations: Analytical Monitoring:
1. .Adding /removing parameters... First SW permit (1995): BOD, COD, TSS, TKN, Nitrate + Nitrite, TP, pH,
Hexamine, Formaldehyde, Lead, Total Rainfall. Second SW Permit (2000): BOD, COD, T-NH3, Nitrate + nitrite

parameters from 2000 permit and...
a. Adding
i. Added TP back into the permit as per 1995 Permit.
ii. Turbidity: TMDL in receiving waters for Turbidity
iii. TPH: Fuel Oil, Diesel Fuel & gasoline stored on site.
iv. Acute Toxicity: Due to the many reports of high levels reported on site exceeding cutoff or
benchmark concentrations, sampling done in -stream and recommendations by RO, and other
reasons testing for acute toxicity is recommended. See attached Acute Toxicity Rational
Document for more detail.

2. Clarification of stormwater outfalls:_
Page 8 of 13

NCS000156 if n�Ft�
a. Hexion's permitted stormwater outfalls are now SW Outfall 003, 004, 006, 008 & 009. The permittee
is responsible for monitoring all of these outfalls. c0_0 17o�4Lµ-�Cj�
b. Some outfalls that were previously monitored (SW 002 & 005) are now on other companies' property.
c. Due to extremely high levels of stormwater parameters exiting outfalls, The DWQ Central office and
DWQ WiRO does not support continued representative outfall status, therefore Hexion must monitor
all Stormwater outfalls.
3. All analytical monitoring has been kept at quarterly during a representative storm event as defined in Part II
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30
days of tf.e end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days
apart, as specified in Table 2.
4. Benchmarks for analytical monitoring and implementation of a Tiered system have been added to this draft
permit. Exceedances of benchmark values require the permittee to increase monitoring, increase
management actions, increase record keeping, and/or install Stormwater Best Management Practices (BMPs)
in a tiered program. if the sampling results are above a benchmark value, or outside of the benchmark range,
for any parameter at any outfall then the facility shall follow the Tier 1 guidelines which require a facility
inspection within two weeks and implementation of a mitigation plan within two months. A special tiered
system for Acute Toxicity is included in Appendix A: Special Conditions at the end of the permit.
S. If during the term of this permit, the sampling results are above the benchmark values, or outside of the
benchmark range, for any specific parameter at a specific discharge outfall three times (not 2 like other
permits — because this is quarterly monitoring) in a row (consecutive), then the facility shall follow the Tier 2
guidelines which require a repetition of the steps listed for Tier 1 and also immediately institute monthly
monitoring for all parameters at every outfall where a sampling result exceeded the benchmark value for
three consecutive samples (this is different than other semi-annual permits). A special tiered system for Acute
Toxicity is included in Appendix A: Special Conditions at the end of the permit.
6. The permittee is required to collect all of the analytical and qualitative monitoring samples during
representative storm events as defined in Part II Section B. Qualitative monitoring is required regardless of
representative-outfall status.
a. The time period between storm events in the definition of a representative storm event has been
changed from 60 days to 30 days.
7. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1,
4, and S.
8. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is
in this permit, however.)
9. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part li
Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do
not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
Pale 9 of 13

NCS000156
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials
and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the facility may
qualify for a No Exposure Exclusion from NPDES. stormwater discharge permit requirements. Additional
information is provided in Part I Section A.
Discussions with permittee: April Hansen 910-655-2263x5248. Micheal A. Lowry is site leader (plant manager).
1. Q: Is this site still called the Acme Facility?
y
a. ANSWER: yes
2. How much are Formaldehyde, Molybdenum, Aniline and Vanadium pentoxide used and where? What is it for
and where is it stored? (Chemicals mentioned in phone conversation].
a. Formaldehyde plant on site. In WW —not sure where it's coming from. They believe that it may have
residuals on equipment. Then it goes out on outfall 4 — which is elevated compared to others.
b. Molybdenum — in oak bark — in Men trex. A food additive for feedstock (cattle). Molybdenum
mentioned in conversation.
c. Vanadium pentoxide= raw material used. Only have raw material onsite when making a botch. All the
raw material is used. Only used it once this year. Typically use 2-3 times per year. Depends on
customers' orders. Used far resin manufacturing. Powder. Stored inside liners, inside 20 or 30 gal
drums. Moved to reactor, liner removed and put inside reactor. Entire liner and hands put in reactor.
Employees wear respirators. Those liners are put in hoz waste drum. (acute hoz waste). Picked up by
haz waste company.
d. Aniline — end of 2008 they discontinued use of that resin product. The tank for that has been cleaned
and disposed of offsite through hoz. Waste company. —
3. Where is haz waste sorted?
a. Stored inside warehouse. Use Ashland environmental. Prior to that using Univar.
4. What types of Chlorine do you use? What exposure to Chlorine does SW have at your facility? Why has the
NDPES WW permit added TRC? What is it for and where is it stored?
a. Were not using chlorine on the site— was implemented because of NPDES WW's concern about the
receiving stream.
S. Do you use a lot of Toluene? You did not list in your attachment to form 2F but it is listed as a pretty large
release in the EPA TRI. What is it for and where is it stored?
a. Do not use Toluene. They bought in 2007. Fuel oil shows a trace amount of toluene. There is probably
more toluene at Oak Bark orSllar...
6. In next 6 months, will be switching to natural gas rather than fuel oil. Right now fuel oil is stored in secondary
containment.
7. Ammonia: There appear to be many forms of ammonia at the site (Ammonium chloride, ammonium
hydroxide, ammonium sulfate, anhydrous ammonia) delivered by truck in both the solid and liquid form. What
is it for and where is it stored?
a. Answer: They have anhydrous ammonia, aqueous ammonia (18.5%-30%)
Page 10 of 13

NCS000156
i. They have a lot of wastewater; they make aqueous ammonia and sell to some Fertilizer
Companies as a raw material. They also sell to International Paper. They are releasing
upstream of flexion/Oak Bark and Silar. They use in WWTP for WW process (breaking down
cellulose?)?
b. Use anhydrous ammonia on railcars, brought in on railcar. Gaseous — under pressure so it liquid. Use
to make the aqueous ammonia. Liquid.
i. Also feeds hexamine plant —used to make hexamine.
c. Ammonium sulfate = aqueous ammonia.
d. Ammonium chloride is from a resin that they are no longer producing.
8. Aniline? What is it used for and where is it stored?
a. Was used for PD13 that is no longer manufactured.
9. Methanol: How much do you have and where? _
~ a. We have 3 storage tanks, one is going to be taken out of service. Two 30,000 gallon tanks are used to
store the methanol. It's used in the manufacturing of formaldehyde. The formaldehyde is used in the
manufacturing of hexamine and in resins (ketone formaldehyde resins). These tanks have secondary
containment. All tanks have secondary containment. They keep all logs of containment draining —
whether they pump out and use and pump out to the WWTP. They are piped and pumped the
formaldehyde process. The design of the plant is such that any venting of the plant goes to the
formaldehyde process.
b. Hexion provides shared WW
10. Have not done any updating of the plant itself. Where the plant is breaking, everything is being sent to the
proper agency before those pipes, plant changes are made-
11. Sulfur: How much do you have on site, what is it used for and where is it stored?
a. Found in fuel oil, allowed to receive 2% S. They have to receive certification. _
12. Ferric chloride — Do you have any and what is it used for, where is it stored? V
a. Used in wastewater = in WWTP. Stored inside.
13. What are the possible sources of the metals and what outfalls would they most likely appear at?
a. Don't know where the metals are coming from. Hexion hopes to see a cleaner discharge. Trying to
separate discharge. Have the 3 companies. Have tried to change the grading and store more
materials inside. Some in fuel oil. Oak Bark manufactures Mentrix: Iron, copper and manganese.
14. Did you test for other metals? Why or why not?
a. Have not done any recent testing for other metals. Not more than what is currently required under old
permit tests.
15. Do you have any Boiler blow -down co -mingling with any stormwater outfalls? If so what outfalls?
a. No. The blowdown is routed to WWTP and the county POTW.
16. Seems like here has been some confusion with knowing which outfalls to sample. Which of those are you
sampling?
a. Couldn't find anything describing ROS so are continuing to sample all other outfalls.
17. What are the "Bridge" Outfalls?
a. Bridge — was representative sampling point. Was where outfalls 2 and 6 discharge. 2 (now Silar) has
its own weir, and 6 is outfall from the duck pond. Now sampling 2 & 6 separately.
18. Are there any issued with water crossing the berm near Oak -Bark outfall 002?
Page l 1 of 13

NCS000156
a. They have installed a speed bump and improved the grading — the speed bump serves to route the
stormwater. The only thing that goes to 6 is the area around duck pond, the pond itself, and some
water running from the Wright Corporation (Acme Fertilizer Plant) — at one point in time the Wright's
sold it to Kaiser chemical. Now it is superfund cleanup site -- on NPL national priorities list. The
groundwater monitoring belongs to Oak Bark in their sales contract/shored services contract. Oak
Bark has a groundwater permit. Silar, LLC may have a well by or near outfall 5. The groundwater
monitoring wells (She believes) belong to Oak Bark. Hexion has some wells by the lined lagoon. The
lined lagoon is going to be permitted under the APS as a recycle system. '^

chemicals stored on site (because of financial concerns, large numbers of parameters, or other
concerns), even if we know what all the chemicals are;
o OWQ may not have benchmarks available for all parameters that may be discharged from the site;
b DWQ may not be able to predict environmental effects from mixed chemicals or chemicals
produced by reactions when mixed that may be discharged from the site;
o DWQ may not be able to know all chemicals that may be discharged from the site or these
chemicals, or information about them, may be proprietary in nature;
o DWQ may be concerned that the toxicity of some parameters (such as copper or other metals)
may be difficult to predict due to variable environmental influences such as hardness, pH, etc.
Description of Onsite Activities:
• Hexion Specialty Chemicals, Inc. manufactures formaldehyde by reacting acetone and methanol in an
aqueous process. Flexion then processes the formaldehyde and anhydrous ammonia to produce
hexamine and specialty Kenton resin products. Hexamine production is classified by SIC code 2869 —
regdlated under 40 CFR part 414, Subpart H — Specialty Organic Chemicals. Hexion also produces
formaldehyde derivatives.
• It is a privately owned organic chemical manufacturing plant utilizing a biotrol WWTP to treat
industrial WW. The WW treatment system utilized holding tanks, ion exchange units, bioreactors,
clarifiers, bag filters and discharge tanks.
• The facility currently operated under 3 permits (2 ww for each facility_and ? sw) originally issued to
Wright Corp. which% become Zs .parate facilities — Oak Barkcnl exion. Currently Flexion takes
responsibiltity for all SW discharges although some SW originates on Oak -Bark Property —
{necessltatrng
the need for sw outfalls os SW leaves Oak -Bark Prop). At this writing, Stormwater permits are being
rated for each of the 3 facilities and issued concurrently.

2. General Observations:
• Analytical Monitoring is regularly high. Average values for BOD= 145, COD=724, TSS=69 (but
regularly exceeding benchmark), NH3=323 mg/l, TKN=183, no2-no3=22. FOR parameters COD, BOD, TSS,
NH3 and TKN there were more exceedences than non-exceedences.
• Hexion's permitted stormwater outfalls are now SW Outfall 003, 004, 006, 008 & 009 'r
• Monitoring must remain quarterly.
• Site is split up. Hexion must sample all of their outfalls — no representative outfalls status
recommended. 1r
• Appears that from RO's comments and recent sampling there has not been much response to
exceeded cut-off concentrations. N,
EPA form 2F lists:
o Formaldehyde, Molybdenum, Aniline and Vanadium pentoxide as chemicals currently use.
• TRI lists Toluene
• No monitoring or benchmarks required in EPA 2008 MSGP for this activity.

• NCS000155
a. Hexion's permitted stormwater outfalls are now SW Outfall 003, 004, 006, 008 & 009. The permittee
is responsible for monitoring all of these outfalls.
b. Some outfalls that were previously monitored (SW 002 & 005) are now onother companies' property.
c. Due to extremely high levels of stormwater parameters exiting outfalls, The DWQ Central office and
DWQ WjR0 does not support continued representative outfall status, therefore Hexion must monitor
all stormwater outfalls.
3. All analytical monitoring has been kept at quarterly during a representative storm event as defined in Part II
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30
days of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days
apart, as specified in Table 2.
4. Benchmarks for analytical monitoring and implementation of a Tiered system have been added to this draft
permit. Exceedances of benchmark values require the permittee to increase monitoring, increase
management actions, increase record keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a benchmark value, or outside of the benchmark range,
for any parameter at any outfall then the facility shall follow the Tier 1 guidelines which require a facility
inspection within two weeks and implementation of a mitigation plan within two months. A special tiered
system for Acute Toxicity is included in Appendix A: Special Conditions at the end of the permit.
S. If during the term of this permit, the sampling results are above the benchmark values, or outside of the
benchmark range, for any specific parameter at a specific discharge outfall three times (not 2 like other
permits — because this is quarterly monitoring) in a row (consecutive), then the facility shall follow the Tier 2
guidelines which require a repetition of the steps listed for Tier 1 and also immediately institute monthly
monitoring for all parameters at every outfall where a sampling result exceeded the benchmark value for
three consecutive samples (this is different than other semi-annual permits). A special tiered system for Acute
Toxicity is included in Appendix A: Special Conditions at the end of the permit.
6. The permittee is required to collect all of the analytical and qualitative monitoring samples during
representative storm events as defined in Part 11 Section B. Qualitative monitoring is required regardless of
representative outfall status.
a. The time period between storm events in the definition of a representative storm event has been
changed from 60 days to 30 days.
7. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1,
4, and S.
8. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is
in this permit, however.)
9. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part 11
Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part 11 Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part 11 Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do
not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
Page 9 of 13

NCS000156
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials
and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the facility may
qualify for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional
information is provided in Part I Section A.
Discussions with permittee: April Hansen 910-655-2263x5248. Micheal A. Lowry is site leader (plant manager).
1. Ci: Is this site still called the Acme Facility?
a. ANSWER: yes
2. How much are Formaldehyde, Molybdenum, Aniline and Vanadium pentoxide used and where? What is it for
anrd where is it stored? (Chemicals mentioned in phone conversation).
a. Formaldehyde plant on site. In WW —not sure where it's coming from. They believe that it may have
residuals on equipment. Then it goes out on outfoll 4 — which is elevated compared to others.
b. Molybdenum —in oak bark —in Mentrex. A food additive for feedstock (cattle). Molybdenum
mentioned in conversation.
c. Vanadium pentoxide= raw material used. Only have raw material onsite when making a batch. All the
raw material is used. Only used it once this year. Typically use 2-3 times per year. Depends on
customers' orders. Used for resin manufacturing. Powder. Stored inside liners, inside 20 or 30 gal
drums. Moved to reactor, liner removed and put inside reactor. Entire liner and hands put in reactor.
Employees wear respirators. Those liners are put in haz waste drum. (acute haz waste). Picked. up by
haz waste company.
d. Aniline — end of 2008 they discontinued use of that resin product. The tank for that has been cleaned
and disposed of offsite through hoz. Waste company.
3. Where is haz waste sorted?
a. Stored inside warehouse. Use Ashland environmental. Prior to that using Univar.
4. What types of Chlorine do you use? What exposure to Chlorine does SW have at your facility? Why has the
NDPES WW permit added TRC? What is it for and where is it stored?
a. Were not using chlorine on the site —was implemented because of NPDES WW's concern about the
receiving stream.
5. Do you use a lot of Toluene? You did not list in your attachment to form 2F but it is listed as a pretty large
release in the EPA TRI. What is it for and where is it stored?
a. Do not use Toluene. They bought in 20OZ Fuel oil shows a trace amount of toluene. There is probably
more toluene at Oak Bark orSilor...
6. in next 6 months, will be switching to natural gas rather than fuel oil. Right now fuel oil is stored in secondary
containment.
7. Ammonia: There appear to be many forms of ammonia at the site (Ammonium chloride, ammonium
hydroxide, ammonium sulfate, anhydrous ammonia) delivered by truck in both the solid and liquid form. What
is it for and where is it stored?
a. Answer. They have anhydrous ammonia, aqueous ammonia (18.5%-30%)
Page 10 of 13

1I
NC:S000156
They have a lot of wastewater; they make aqueous ammonia and sell to some Fertilizer
Companies as a raw material. They also sell to International Paper. They are releasing
upstream of Hexion/Oak Bark and Silar. They use in WWTP for WIN process (breaking down
cellulose?)?
b. Use anhydrous ammonia on railcars, brought in on railcar. Gaseous — under pressure so it liquid. Use
to make the aqueous ammonia. Liquid.
i. Also feeds hexamine plant — used to make hexamine.
c. Ammonium sulfate = aqueous ammonia.
d. Ammonium chloride is from a resin that they are no longer producing.
8. Aniline? What is it used for and where is it stored?
a. Was used for PD13 that is no longer manufactured.
9. Methanol: How much do you have and where?
a. We have 3 storage tanks, one is going to be taken out of service. Two 30,000 gallon tanks are used to
store the methanol. It's used in the manufacturing of formaldehyde. The formaldehyde is used in the
manufacturing of hexamine and in resins (ketone formaldehyde resins). These tanks have secondary
containment. All tanks have secondary containment. They keep all logs of containment draining —
whether they pump out and use and pump out to the WWTP. They are piped and pumped the
formaldehyde process. The design of the plant is such that any venting of the plant goes to the
formaldehyde process.
b. Hexion provides shared WW
10. Have not done any updating of the plant itself Where the plant is breaking, everything is being sent to the
proper agency before those pipes, plant changes are made.
11. Sulfur: How much do you have on site, what is it used for and where is it stored?
a. Found in fuel oil, allowed to receive 2% S: They have to receive certification.
12. Ferric chloride — Do you have any and what is it used for, where is it stored?
a. Used in wastewater = in WWTP. Stored inside.
13. What are the possible sources of the metals and what outfalls would they most likely appear at?
a. Don't know where the metals are coming from. Hexion hopes to see a cleaner discharge. Trying to
separate discharge. Have the 3 companies. Have tried to change the grading and store more
materials inside. Some in fuel oil. Oak Bark manufactures Mentrix: Iron, copper and manganese.
14. Did you test for other metals? Why or why not?
a. Have not done any recent testing for other metals. Not more than what is currently required under old
permit tests.
15. Do you have any Boiler blow -down co -mingling with any stormwater outfalls? If so what outfalls?
a. No. The blowdown is routed to WWTP and the county POTW.
16. Seems like here has been some confusion with knowing which outfalls to sample. Which of those are you
sampling?
a_ Couldn't find anything describing ROS so are continuing to sample all other outfalls.
17. What are the "Bridge" Outfalls?
a. Bridge — was representative sampling point. Was where outfalls 2 and 6 discharge. 2 (now Sitar) has
its own weir, and 6 is outfall from the duck pond. Now sampling 2 & 6 separately.
18. Are there any issued with water crossing the berm near Oak -Bark outfall 002?
Pape l 1 of 13

NCS000156
a. They have installed a speed bump and improved the grading - the speed bump serves to route the
stormwater. The only thing that goes to 6 is the area around duck pond, the pond itself, and some
water running from the Wright Corporation (Acme Fertilizer Plant) - at one point in time the Wright's
sold it to Kaiser chemical. Now it is superfund cleanup site - on NPL national priorities list. The
groundwater monitoring belongs to Oak Bark in their sales contract shared services contract. Oak
Bark has a groundwater permit. Silar, LLC may hove a well by or near outfall 5. The groundwater
monitoring wells (She believes) belong to Oak Bark. Hexion has some wells by the lined lagoon. The
lined lagoon is going to be permitted under the APS as a recycle system.

The permit has been modified after the staff report was written.
1. WiRO Staff suggested outfall 008 have only O&G, lead, copper, zinc, TSS, BOD, TN and pH. I
revised 008 based on what I saw from the monitoring and BP1, so I included TKN, NO3-NO2-N,
ammonia N (as we didn't have TN parameter), Hexamine (as it appears to be ubiquitous over
the site), and Formaldehyde (as also present at 008 in testing)_
2. 1 changed TP monitoring to first 8 consecutive samples only after Discussion with BG and BL. I
decided that it had only been added as it was in 1995 permit and because they had very large
BOD and COD exceedences. So changed it- if don't have an exceedences in first 8 samples,
permittee is no longer required to sample for TP.
3. Qualitative monitoring was modified between the draft permit issuance and the final permit
from Semi-annual monitoring to quarterly monitoring. This was done to be the equivalent
monitoring schedule as Silar and Oak -Bark.
4. In response to the draft permit public notice period, Hexion asked to add "Stormwater outfalls
applicable to Hexion, Specialty Chemicals, Inc. and referred to in this individual stormwater
permit are SW outfalls 003, 004, 006, 008 and 009." We typically only write SDO. In light of any
possible dispute over discharges between sites and the possibility of adding another stormwater
outfall to Hexion, we will keep outfalls as "SDO" for all outfalls (with the exception of the named
outfalls for certain parameters) for all 3 sites — Hexion, Silar and Oak Bark. See email exchange

Subject: RE: Hexion's monitoring
Jen and Rick,
My opinion is that we leave the permit as drafted. Silar did mention concerns with the location of the
methanol storage. Adding that parameter to Silar s permit at this point wouldn't be received well, I
wouldn't think. If methanol is a problem for Silar, it will show up as COD at their outfall 005. If COD is
high at 005 but cannot be associated with any pollutants from Sitar's production area, Silar can do
additional testing to see if it is methanol.

Subject: Hexion's monitoring
Hi Linda,
We went over this last week but I just wanted another confirmation after our meeting today. It seemed
like Silar was concerned about the monitoring for methanol from outfall 001. Methanol was one of the
4 parameters that we agreed should only be monitored from 4 outfalls (see table below).
My uuestions are:
1. i couldn't hear on the phone very well —was it Methanol they were concerned about from
outfall 001 or was it another Parameter?
2. Should with we stick with this monitoring scheme and name the outfalls for these 4
parameters? My concern here is that if methanol is a problem at 001, then.Silar might look to
Hexion to fix it, but Hexion's permit will state that Hexion only needs to monitor these 4 specific
outfalls for Methanol. We could change the permit but that might cause a bit of a fuss.
I am not sure that this is the case because I couldn't see what was going on, so phase let me know your
opinion on this. Thank you!
Jen

�' • Addition of Acute Toxicity to permit due to many repeated and egregious benchmark exceedences. See
attached Rational for Acute Toxicity use. NC DWQ believes acute toxicity may be a useful parameter in
ca ses where:
o DWQ cannot feasibly include all test parameters in a permit or ask the permittee to test specific
chemicals stored on site (because of financial concerns, large numbers of parameters, or other
concerns), even if we know what all the chemicals are;
o DWQ may not have benchmarks available for all parameters that may be discharged from the site;
o DWQ may not be able to predict environmental effects from mixed chemicals or chemicals
produced by reactions when mixed that may be discharged from the site;
o DWQ may not be able to know all chemicals that may be discharged from the site or these
chemicals, or information about them, may be proprietary in nature;
o DWQ may be concerned that the toxicity of some parameters (such as copper or other metals)
may be difficult to predict due to variable environmental influences such as hardness, pH, etc.
Description of Onsite Activities:
• Hexion Specialty Chemicals, Inc. manufactures formaldehyde by reacting acetone and methanol in an
aqueous process. Hexion then processes the formaldehyde and anhydrous ammonia to produce
hexamine and specialty Kenton resin products. Hexamine production is classified by SIC code 2869 —
regulated under 40 CFR part 414, Subpart H —Specialty Organic Chemicals. Hexion also produces
formaldehyde derivatives.
• It is a privately owned organic chemical manufacturing plant utilizing a biotrol WWTP to treat
industrial WW. The WW treatment system utilized holding tanks, ion exchange units, bioreactors,
clarifiers, bag filters and discharge tanks.
• The facility cu rently operat? unde__ r 3_permits (2 ww for each facility and_ 1 sw) originally issued to
Wright Corp. which as, become Zseparate facilities — Oak Bark,aricTHexion. Currently Hexion takes
responsibiltity for all SW discharges although some SW originates on Oak -Bark Property — (necessitating
the need for sw outfalls as SW leaves Oak -Bark Property). At this writing, Stormwater permits are being
rated for each of the 3 facilities and issued concurrently.

2. General Observations:
• Analytical Monitoring is regularly high, Average values for BOD= 145, COD=724, T5S=69 (but
regularly exceeding benchmark), NH3=323 mg/I, TKN=183, no2-no3=22. FOR parameters COD, BOD, TSS,
NH3 and TKN there were more exceedences than non-exceedences.
• Hexion's permitted stormwater outfalIs are now SW Outfall 003, 004, 006, 008 & 009
• Monitoring must remain quarterly.
• Site is split up. Hexion must sample all of their outfalls — no representative outfalls status
recommended. 1.-
• Appears that from RO's comments and recent sampling there has not been much response to
exceeded cut-off concentrations.
• EPA form 2F lists:
o Formaldehyde, Molybdenum, Aniline and Vanadium pentoxide as chemicals currently use.
• TRI lists Toluene
• No monitoring or benchmarks required in EPA 2008 MSGP for this activity.
TRI Total Releases and Transfers by Chemical and Year
Chemical releases and transfers are in pounds except where otherwise noted.

3. Impairment: Aquatic life is impaired in Livingston Creek (Broadwater Lake) for Turbidity.
4. Threatened and Endangered: No threatened or endangered aquatic animals are near the I iexion facility.
5. Location:
• Site split up from one owner- Wright Chemical - into 3 owners and changed name. Now this permit
(the oldest #) is linked to Hexion Specialty Chemicals, Inc.
• Outfalls and responsibilities need to be defined for each company.
6. Industrial Changes Since Previous Permit: Site and outfalls split up -see above notes. Constructed additional
cooling tower, new hexamine warehouse, and milling operation building. Also new pharmaceutical production
building and new storage tanks.
7. Analytical Monitoring Notes: See General observations and monitoring spreadsheet below.

Hexamine, Formaldehyde, Lead, Total Rainfall. Second SW Permit (2000): BOD, COD, T-NH3, Nitrate + nitrite
N, TKN, TSS, pH, Hexamine, formaldehyde, Total lead, total rainfall total duration, total flow. Keeping
parameters from 2000 permit and...
a. Adding
L Added TP back into the permit as per 1995 Permit.
ii. Turbidity: TMDL in receiving waters for Turbidity
iii. TPH: Fuel Oil, Diesel Fuel & gasoline stored on site.
iv.; Acute Toxicity: Due to the many reports of high levels reported on site exceeding cutoff or
benchmark concentrations, sampling done in -stream and recommendations by RO, and other
reasons testing for acute toxicity is recommended. See attached Acute Toxicity Rational
�.•�',,'' Document for more detail.
-v. Methanol: 2F Attachment A indicates a large amount is stored onsite.
vi. Total Copper: Based on data turned in by permittee on form 2F

2. Clarification of stormwater outfalls: ,, cc
-,, ,-•_., r �,,�
Page 8 of 13

NCSOOO 156
a. Hexion's permitted stormwater outfalls are now SW Outfall 003, 004, 006, 008 & 009. The permittee
is responsible for monitoring all of these outfalls.
b. Some outfalls that were previously monitored (SW 002 & 005) are now on other companies' property.
c. Due to extremely high levels of stormwater parameters exiting outfalls, The DWQ Central office and
DWQ WiRO does not support continued representative outfall status, therefore Hexion must monitor
all Stormwater outfalls.
3. All analytical monitoring has been kept at quarterly during a representative storm event as defined in Part II
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30
days of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days
apart, as specified in Table 2.
4. Benchmarks for analytical monitoring and implementation of a Tiered system have been added to this draft
permit. Exceedances of benchmark values require the permittee to increase monitoring, increase
management actions, increase record keeping, and/or install stormwater Best Management Practices (BMPs)
in a.tiered program. If the sampling results are above a benchmark value, or outside of the benchmark range,
for any parameter at any outfall then the facility shall follow the Tier 1 guidelines which require a facility
inspection within two weeks and implementation of a mitigation plan within two months. A special tiered
system for Acute Toxicity is included in Appendix A. Special Conditions at the end of the permit.
5. if during the term of this permit, the sampling results are above the benchmark values, or outside of the
benchmark range, for any specific parameter at a specific discharge outfall three times (not 2 like other
permits -- because this is quarterly monitoring) in a row (consecutive), then the facility shall follow the Tier 2
guidelines which require a repetition of the steps listed for Tier 1 and also immediately institute monthly
monitoring for all parameters at every outfall where a sampling result exceeded the benchmark value for
three consecutive samples (this is different than other semi-annual permits). A special tiered system for Acute
Toxicity is included in Appendix A: Special Conditions at the end of the permit.
6. The permittee is required to collect all of the analytical and qualitative monitoring samples during
representative storm events as defined in Part 11 Section B. Qualitative monitoring is required regardless of
representative outfall status.
a. The time period between storm events in the definition of a representative storm event has been
changed from 60 days to 30 days.
i. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1,
4, and 5.
8. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is
in this permit, however.)
9. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II
Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part 11 Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do
not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
Page 9 of I3

NCS000156
management controls as specified in Part II Section A.
5. Infornnation regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials
and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the facility may
qualify for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional
information is provided in Part I Section A.
Discussions with permittee: April Hansen 910-655-2263x5248. Micheal A. Lowry is site leader (plant manager).
1. Ca: Is this site still called the Acme Facility?
a. ANSWER: yes
2. How much are Formaldehyde, Molybdenum, Aniline and Vanadium pentoxide used and where? What is it for
and where is it stored? [Chemicals mentioned in phone conversation].
a. Formaldehyde plant on site. In WW —not sure where it's coming from. They believe that it may have
residuals on equipment. Then it goes out on outfall 4 — which is elevated compared to others.
b. Molybdenum — in oak bark — in Mentrex. A food additive for feedstock (cattle). Molybdenum
mentioned in conversation.
c. Vanadium pentoxide= raw material used. Only have raw material onsite when making a batch. All the
raw material is used. Only used it once this year. Typically use 2-3 times per year. Depends on
customers' orders. Used far resin manufacturing. Powder. Stored inside liners, inside 20 or 30 gal
drums. Moved to reactor, liner removed and put inside reactor. Entire liner and hands put in reactor.
Employees wear respirators. Those liners are put in haz waste drum. (acute haz waste). Picked up by
haz waste company.
d. Aniline —end of 2008 they discontinued use of that resin product. The tank for that has been cleaned
and disposed of offsite through hoz. Waste company.
3. Where is haz waste sorted?
a. Stored inside warehouse. Use Ashland environmental. Prior to that using Univar.
4. What types of Chlorine do you use? What exposure to Chlorine does SW have at your facility? Why has the
NDPES WW permit added TRC? What is it for and where is it stored?
a. Were not using chlorine on the site —was implemented because of NPDES WW's concern about the
receiving stream.
5. Do you use a lot of Toluene? You did not list in your attachment to form 2F but it is listed as a pretty large
release in the EPA TRI. What is it for and where is it stored?
a. Do not use Toluene. They bought in 2007. Fuel -oil shows a trace amount of toluene. There is probably
more toluene at Oak Bark or Silar...
6. In next 6 months, will be switching to natural gas rather than fuel oil. Right now fuel oil is stored in secondary
containment.
7. Ammonia: There appear to be many forms of ammonia at the site (Ammonium chloride, ammonium
hydroxide, ammonium sulfate, anhydrous ammonia) delivered by truck in both the solid and liquid form. What
is it for and where is it stored?
a. Answer: They have anhydrous ammonia, aqueous ammonia (18.5%-30%)
Page 10 of 13

NCS(W 156
i. They have a lot of wastewater; they make aqueous ammonia and sell to some Fertilizer
Companies as a raw material. They also sell to International Paper. They are releasing
upstream of Hexion/Oak Bark and Silar. They use in WWTP for WW process (breaking down
cellulose?)?
b. Use anhydrous ammonia on railcars, brought in on railcar. Gaseous —under pressure so it liquid. Use
to make the aqueous ammonia. Liquid.
i. Also feeds hexamine plant — used to make hexamine.
c. Ammonium sulfate = aqueous ammonia.
d. Ammonium chloride is from a resin that they are no longer producing.
8. Aniline? What is it used for and where is it stored?
a. Was used for PD13 that is no longer manufactured.
9. Methanol: How much do you have and where?
a. We have 3 storage tanks; one is going to be taken out of service. Two 30,000 gallon tanks are used to
store the methanol. It's used in the manufacturing of formaldehyde. The formaldehyde is used in the
manufacturing of hexamine and in resins (ketone formaldehyde resins). These tanks have secondary
containment. All tanks have secondary containment. They keep all logs of containment draining --
whether they pump out and use and pump out to the WWTP. They are piped and pumped the
formaldehyde process. The design of the plant is such that any venting of the plant goes to the
formaldehyde process.
b_ Hexion provides shared WIN
10. Have not done any updating of the plant itself. Where the plant is breaking, everything is being sent to the
proper agency before those pipes, plant changes are made.
11. Sulfur: How much do you have on site, what is it used for and where is it stored?
a_ Found in fuel oil, allowed to receive 2% S. They have to receive certification.
12. Ferric chloride — Do you have any and what is it used for, where is it stored?
a. Used in wastewater = in WWTP. Stored inside.
13. What are the possible sources of the metals and what outfalls would they most likely appear at?
a. Don't know where the metals are coming from. Hexion hopes to see a cleaner discharge. Trying to
separate discharge. Have the 3 companies. Have tried to change the grading and store more
materials inside. Some in fuel oil. Oak Bark manufactures Mentrix: iron, copper and manganese.
14. Did you test for other metals? Why or why not?
a. Have not done any recent testing for other metals. Not more than what is currently required under old
permit tests.
15. Do you have any Boiler blow -down co -mingling with any stormwater outfalls? If so what outfalls?
a. No. The blowdown is routed to WWTP and the county POTW.
16. Seems like here has been some confusion with knowing which outfalls to sample. Which of those are you
sampling?
a. Couldn't find anything describing ROS so are continuing to sample all other outfalls.
17. What are the "Bridge" outfalls?
a. Bridge — was representative sampling point. Was where outfalls 2 and 6 discharge. 2 (now Silar) has
its own weir, and 6 is outfall from the duck pond. Now sampling 2 & 6 separately.
18. Are there any issued with water crossing the berm near Oak -Bark outfall 002?
Page i 1 of 13

NCSOOO 156
a. They have installed a speed bump and improved the grading — the speed bump serves to route the
stormwater. The only thing that goes to 6 is the area around duck pond, the pond itself, and some
water running from the Wright Corporation (Acme Fertilizer Plant) — at one point in time the Wright's
sold it to Kaiser chemical. Now it is superfund cleanup site — on NPL national priorities list. The
groundwater monitoring belongs to Oak Bark in their sales contract/shared services contract. Oak
Bark has a groundwater permit. Silar, LLC may hove a well by or near outfall S. The groundwater
monitoring wells (She believes) belong to Oak Bark. Hexion has some wells by the lined lagoon. The
lined lagoon is going to be permitted under the APS as a recycle system.

stormwater discharges. The site plan shall contain tlie;foliowing:
(a) A general location map (USGS quadrangle^map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation routes
and surface waters, the name of the'ree-eiving:water(s) to which the stormwater
outfall(s) discharges, or if the discharge_is to a municipal separate storm sewer
system, the name of the municipality and the ultimate receiving; waters, and
accurate Iatitude and longitude' i e point(s) of discharge. The general location
map {or alternatively�he-sitemap} shall identify whether each receiving water is
impaired (on the status 303(d)`list of impaired waters) or is located in a

watershed for whkh'a TMDL has been established, and what the parameter(s)
of concern are.�''� _ ,X `-
(b) A narrative -description of storage practices, loading and. unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance Iegend) showing: the site property
boundary, the stormwater discharge outfalls, all on -site and adjacent surface
waters and wetlands, industrial activity areas (including storage of materials,
disposal areas, process areas, loading and unloading areas, and haul roads), site
topography, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (3) previous years and any corrective actions taken to mitigate

Permit No. NCS000156
B, Paragraph 5_ The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. 'Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas_where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away fro -in areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in' any amount of hazardous substances, in
order to prevent leaks and `spills from contaminating stormwater runoff. A table
or summary of all such. tanks and stored materials and their associated secondary
containment areas shall.be maintained. If the secondary containment devices are
connected to stoi=mwater conveyance systems, the connection shall be controlled
by manually activated valves or other similar devices (which shall be secured
closed with a locking mechanism), and any stormwater that accumulates in the
containment Z; "CYshall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated storrwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges_ The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
person shall be on -site at all times during facility operations that have the potential to
Part II Page 2 of 10

Permit No. NCS000156
contaminate Stormwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP,
but may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance `and- good housekeeping program shall be developed. The program shall list
all stormwater control systems, stormwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,
material handling -areas, disposal areas, process areas, loading and unloading areas, and
haul roads), afi drainage features and structures, and existing structural BMPs. The
program shall establish schedules of inspections;lmaintenance, and housekeeping
activities of Stormwater control systems, as well as, facility egui ment, facility areas, and
facility systems that present a potential for stormwater exposure or stormwater pollution.
Inspection of material handling areas and regula'`r Hdaning-schedules of these areas shall
,mot.
be incorporated into the program. Timelycompliance with the established schedules for
t.inspections, maintenance, and housekeeping %al, lobe recorded in writing and maintained
in the SPPP.
5. Employee Training. Training programsrMll be developed and training provided at a
441
minimum on an. annual basisfor facility, personnel with responsibilities for: spill response
and cleanup, preventative, maintenance activities, and for any of the facility's operations
that have the potential _to �cont a iimate stormwater runoff. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be docurn.,ntedby,the signature of each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part 11 Page 3 of 10

have been made.
S. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as
part of the Preventative Maintenance and Good Housekeeping Program at a minimum on
a semi-annual schedule, once during the first half of the year (January to June), and once
during the second half (July to December), with at least 60 days separating inspection
dates (unless performed more frequentiy than semi-annually). These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part II B and C of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
shall include documentation of all monitoring, measurements, inspections, maintenance
activities, and training provided to employees, iricluding<the log of the sampling data and
of actions taken to implement BMPs associated with'the_indusfrial activities, including
vehicle maintenance activities. Such documentation shalYlheukept on -site for a period of
five years and made available to the Director drIthe";Director's authorized representative
immediately upon request.;'
SECTION B: ANALYTICAL MONITORINGREQUIREMENTS
Analytical monitoring of stop-nwater discharges' shall be performed as specified in Table 1. All
analytical monitoring shall be perfo medVduring a representative storm event. The required
monitoring will result in a minimum of_twerity analytical samplings being conducted over the
term of the permit at each stormwater discharge outfail (SDO).
A representative storm event -is a storm event that measures greater than 0.1 inches of rainfall. The time
between this storm event and tl e`previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
Droducine a discharve be2ins within 10 hours.

Dear Mr. Lowry:
Dee Freeman
Secretary
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit.
Analtical monitoring changes:
1. Analytical monitoring parameters have been added to this permit.
2. pH has been added to the analytical monitoring requirements.
3. Representative outfall status has not been granted as of yet. Please continue to monitor all outfalls. You
may apply for Representative Outfall Status through the Linda Willis at the Wilmington Regional Office.
4. All analytical monitorie - has been set to quarterly during a r6presehiative storm event as defined in Part
H Section B. The permittee must also document the total precipitation for each event. If no discharge
occurs during the sampling period, the permittee must submif a monitoring report indicating "No Flow"
within 30 days of the end of the three-month sampling period. Additionally, samples must be taken a
minimum of 30 days apart, as specified in the text directly above Table 2.
5. Benchmarks for analytical monitoring have been added to this draft permit Exceedances of benchmark
values require the permittee to increase monitoring, increase management actions, increase record
keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered program. For all
parameters except Acute Toxicity: if the sampling results are above a benchmark value, or outside of the
benchmark range, for any parameter at any outfall then the facility shall follow the Tier 1 guidelines
which require a facility inspection within two weeks and implementation of a mitigation plan within two
months. If during the term of this permit, the sampling results are above the benchmark values, or
outside of the benchmark range, for any specific parameter at a specific discharge outfall two times in a
row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of the
steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every
outfall where a sampling result exceeded the benchmark value for two consecutive samples. For
benchmarks and sampling requirements regarding acute toxicity, please see Appendix A: Special
Conditions.
6. You are required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part H Section B. Qualitative monitoring is required regardless of
representative outfall status.
7. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.

8. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)
9. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. Monitoring for TPH has replaced Oil & Grease. This requirement appears in
all Individual Stormwater permits, however it only applies to facilities that do vehicle maintenance. If the
facility begins vehicle maintenance during the permitted timeframe then the requirements shall apply.
Other permit changes:
1. Additional guidance is provided about the SEt; flan requirements. The site map crust now identify if the
receiving stream is impaired and if it has a T1 il—)L e.:;tablished. It must also describe potential pollutants
in each outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past1thrcv years and also must certify that the outfalls have
been inspected to ensure that they do not contain i,,n-stormwater discharges. Additional information is
provided in Part II Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part 11 Section A.
More'details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II
Section A. The plan must also be updated annually to include a list of significant spills and to certify that
the outfalls do not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5_ Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial
materials and activities are not exposed to precipitation or -runoff as described in 40 CFR §122.26(g), the
facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit
requirements. Additional information is provided in Part I Section A.
6. In addition to submitting two signed copies of DMRs to Central Files, a separate signed Annual Summary
DMR copy must be submitted to the local DWQ Regional Office by March 1 of each year. See Part II,
Section E: Reporting Requirements for more information.
7. Additionally, DWQ Form AT-2 for Acute Pass/:Fail Tests (original) is to be sent to the Environmental
Sciences Section annually. See Appendix A: Spc,,,ial Conditions for more information.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] or

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public inform-fation in accordance with Part I11, Standard
Conditions, Section E, Paragraph 3 of this individuatVermit. The Plan shall include, at a
minimum, the following items:
I . Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expcted to c ontribute to contamination of
stormwater discharges. The site plan shall conlain tke.f3llowing:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation routes
and surface waters, the name of the receving.water(s) to which the stormwater
outfall(s) discharges, or if the discharge is to a municipal separate storm sewer
system, the name of the municipality and the ultimate receiving waters, and
accurate latitude and longitude of ihe,point(s) of discharge. The general location
map (or alternatively the -site map)shall identify whether each receiving water is
I
impaired (on the state's.303(dY-list of impaired waters) or is located in a
watershed for wbi a-TMDL has been established, and what the parameter(s)
of concern are! -
(b) A narrative description of storage practi;;;es, loading and unloading activities,
outdoor process areas, eas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description.of the potential pollutants which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: the site property
boundary, the stormwater discharge outfalls, all on -site and adjacent surface
waters and wetlands, industrial activity areas (including storage of materials,
disposal areas, process areas, loading and unloading areas, and haul roads), site
topography, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (3) previous years and any corrective actions taken to mitigate
spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges_ The certification statement will be signed in
accordance with the requirements found in Part 111, Standard Conditions, Section
Part 11 Page 1 of 10

Permit No. NCSfl00156
B, Paragraph 5. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall ; f_
prevent exposure of all storage areas, material -handling operations, and r
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from'areas of potential contamination.
(b) Secondary Containment Requiremerits'and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section
313 of Title Ill of the Superfund Amendments and Reauthorization Act (SARA) .
water priority chemicals; and storage in any amount of hazardous substances, in _
order to prevent leaks and spills !from contaminating stormwater runoff. A table
or summary of all such tanks .and stored materials and their associated secondary
containment areas shall be maintained. If the secondary containment devices are
connected to stormwater conveyance systems, the connection shall be controlled
by manually activated valves or other similar devices (which shall be secured -
closed with a4ocking mechanism), and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BN4Ps
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
person shall be on -site at all times during facility operations that have the potential to
Part H Page 2 of 10

Permit No. NCS000156
contaminate stormwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) maybe a component of the SPRP,
but may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Housekeeping Pr, gram. A preventative
maintenance and good housekeeping program shall be developed. The program shall list
all stormwater control systems, stormwater dischargebihfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,
material handling areas, disposal areas, process areas, loadlp'and unloading areas, and
haul roads), all drainage features and structures, and existing structural BMPs. The
program shall establish schedules of inspections;`maintenance, and housekeeping
activities of stormwater control systems, as well as ,f cility equipment, facility areas, and
facility systems that present a potential for stormwater exposure or stormwater pollution.
Inspection of material handling areas and reguL r:cleaning schedules of these areas shall
be incorporated into the program. Timely, complia�nce with the established schedules for
inspections, maintenance, and housekeepi g shall -be recorded in writing and maintained
in the SPPP.'
5. Employee Training. Trauiing programs -shall be developed and trainirig provided at a
minimum on an annual basis for facility, personnel with responsibilities for: spill response
and cleanup, preventative,maintenance activities, and for any of the facility's operations
that have the potential to contaminate stormwater runoff. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be documented,by�the ignature of each employee trained.
r
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or thenotation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part H Page 3 of 10

Permit No_ NCS000156
Part III, Standard Conditions, Section B, Paragraph 5) to the Director that the changes
have been made.
8. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as
part of the Preventative Maintenance and Good Housekeeping Program at a minimum on
a semi-annual schedule, once during the first half of the year (January to June), and once
during the second half (July to December), with at least 60 days separating inspection
dates (unless performed more frequently than semi-annually). These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part -II B and C of this permit-.
9. Implementation. The permittee shall implern-Mit the Plan. Implementation of the Plan
shall include documentation of all monitoring, measurements, inspections, maintenance
�r
activities, and training provided to employees, including the log of the sampling data and
of actions taken to implement BMPs associated with tli'e:industrial activities, including
vehicle maintenance activities. Such documentation shall-be/kept on -site for a period of
five years and made available to the Director or the'Director's authorized representative
immediately upon request.
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Y- Y /
Analytical monitoring of stormwater discharges shall be performed as specified in Table I. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimumof tweity analytical samplings being conducted over the
term of the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time
between this storm event and tle:previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.

This site discharges to impaired waters experiencing problems with Turbidity. If a Total
Maximum Daily Load (TMDL) is appioved for this segment of Livingston Creek (Broadwater
Lake) the permittee may be required to monitor for the pollutant(s) of concern in the future and
submit results to the Division of Water Quality. The Division will consider the monitoring
results in determining whether additional BMPs are needed to control the pollutant(s) of concern
to the maximum extent practicable.
If additional BMPs are needed.to: achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a timetable
" . for incorporation of those BMPs into the permitted Stormwater Pollution Prevention Plan.
s SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection ofea h..stormwatei: outfall regardless of
representative outfall status and shall be perfoimed as.sp cified ur'Table 4, during the analytical
monitoring event. Qualitative monitoring is for_the purpose of evaluating the effectiveness of the
Stormwater Pollution Prevention Plan (SPPP) and.a sessing new sources -of stormwater pollution.
In the event an atypical condition is noted at affstor`mwater discharge outfall, the permittee shall
document the suspected cause of the condition and.any actions taken in response to the
i AVJ !/.
discovery. This documentation will. be,mauit ined-with the SPPP.

Hi All,
Well I've finally caught up on reading this string of emails. Thank you for all of your comments Ken & Linda and thank
you Nikki for that really thorough explanation of how we (you) use % FAVs and what they really mean.
I just wanted to reply to something Linda mentioned. We do actually have benchmarks in these permits for
Formaldehyde (0.5 mg/1) , Ammonia-N (7.2 mg/1), pH (6-9), COD (120mg/1) and BOD (30 mg/1), So even though
Hexamine's benchmark is really high, if it does dissociate into formaldehyde and ommonio-N and cause a pH/B©DICOD
problem we should be catching all of that. Additionally, it will be interesting to see the relative amounts of hexamine,
formaldehyde, ammonia and pH levels.
And you can see that our formaldehyde benchmark of 0.5 mg/I in this permit is much lower than the WW limit of 7.48
mg/l. So from what Linda has said about GS 143.215.1(a)(4) it seems that our low benchmark for Formaldehyde should
cover us.
I feel pretty confident that we've gotten enough parameters and benchmarks in here to capture the problems with
Formaldehyde, BOD, COD, pH, ammonia, plus all the other parameters we've got in there (TP, Pb, Cu, Zn, etc. etc. etc.).
Sorry it tcok me so long to reply to this! I'll save this to my Hexion file and save a copy to the guidance/benchmarks
folder— it has such a good explanation of how the %: FAVs are. I'll also send out to the rest of the unit. And might send.
out to the other ROs. May be useful for them because I'm sure they get asked about this all the time.

Thanks, Linda.
Yeah, we've issued the 3 permits. A couple of things come to mind as far as our potential subsequent reactions to this
new (to us in SPU, I think) perspective.
a) In 5 years, take this hydrolysis potential into consideration —we really didn't look into the receiving water
chemistry, as far as I know. Linda, your email below needs to be in the file for each of these three permittees.
b) If new owners come on the site, don't just transfer the permit, but take that occasion to look more in-depth at
these questions. I foresee at least one potential difficulty: Is it fair to make one of the three permits different
from the other two on this same site?
c) I think we are pretty certain that all three of these permittees will shortly (1-2 years) be deep into the Tiered
approach. This knowledge of pollutant character should enable us to move them toward response actions that
speak to effective removal of the pollutants. The specifics would have to be worked out at that time.

Subject: RE: Benchmark for Hexamine & Methanol
Ken and Nikki,
I learned a lot from your discussions concerning the benchmark for hexamine. This receiving stream is impaired for low
DO. If we had the benthic folks come in and look at the benthos, my bet is, their dead and long gone. Hexamine is
reported to undergo hydrolysis (UNCW did studies on decomposition products for hexamine). The products of
hydrolysis are ammonia and formaldehyde. Why couldn't we base our hexamine limitation on the toxicity
concentrations associated with ammonia or formaldehyde?
Note in the spreadsheet. . when we have high flows (more stormwater), we seem to see elevated ammonia levels (is
the hexamine undergoing hydrolysis at this point?). Our ambient monitor (Stephanie Garrett) was asked to pull a
sample for formaldehyde in Livingston Creek (we have an ambient station in Livingston Creek). We got a hit for
formaldehyde.. can't remember how much, but for it to show up was a concern and supports perhaps that hexamine is
breaking down into formaldehyde and ammonia.
A concentration of 25,000 mg/L will cause high CODS and BODs. See spreadsheet. Can we establish a benchmark based
upon the limitation that would be the most stringent? Toxicity isn't the one.. unless we look at the products of
hydrolysis. BOD or COD could've been the limiting parameters which would have squeezed that benchmark for
hexamine to a reasonable level. A low pH (too) can cause the dissociation of hexamine into free ammonia. How low,
I'm not sure. If below 6, our receiving water has had occasions of pH that low, and maybe lower.
With a benchmark of 25,000 mg/L, it would seem rather tempting not to pay to have their wastewater treated at the
County's Regional WWTP when they could illicitly allow it's release with stormwater. As a matter of fad, that is exactly
what Wright Chemical did. Hexion found a "green overflow tank" that was used to store hexamine waste for rework.
.yet it had an overflow pipe at the top that would just discharge to the ground and out the stormwater outfall. No
intention to stop a discharge, no alarm system, nothing. I'm glad we have better stewards on site. My impression of our
new permittees is, they care. But, you get my point. If they were poor environmental stewards, that would be
tempting.
Lastly, General Statute 143.215.1(a)(4) has some guidance for us.. no person shall do the following...
(4) increase the quantity of waste discharged through any outlet or processed in any treatment works or disposal
system to any extent that would result in any violation of the effluent standards or limitations established for any point
2

.1
source or that would adversely affect the condition of the receiving waters to the extent of violating any applicable
standard.
And..
Our permit limit in Hexion's NPDES Individual wastewater permit for formaldehyde is 7.48 mg/L. We likely needed a
benchmark at least as stringent as that value for our stormwater permit because of what the GS says above (in red). We
should have considered the formaldehyde likely released when hexamine undergoes hydrolysis and limit the hexamine
concentration accordingly (no more than 7.48 mg/L).
I'm not trying to be a wet blanket here, the new stormwater permit is much more meaningful.. we now have toxicity
monitoring that may take care of our toxicity concerns wholly_ DWQ now has the ability to push for remedies and even
take steps towards reissuance under a wastewater permit if we don't get remedy. We now have mechanisms in these
permits that enables DWQ to provide some direction with expectations that will provide meaningful outcomes. We
didn't have that before.
Thanks for putting up with me. I know, I should've thrown this out before the permit went to draft. I'm not always at
the top of my game when my comments are requested. Usually because I'm fighting alligators with chop sticks. We'll
have another stab at it in 5 years if we aren't happy with their progress. I'm greatly pleased with the permit. I think
we'll see improvements.
Have a wonderful weekend.

Subject: RE: Benchmark for Hexamine & Methanol
Nikki,
Thanks for that further education.
As far as I know we have only 3 permittees in the stormwater program with hexamine benchmarks in the permit. All
three are successor companies located on the old Wright Chemical site on Livingston Creek in northeast Columbus
County. Hexamine is manufactured at one of the successor sites (I think it's manufactured on site, and sold as an
intermediate for other chemical formulations and processes.) The site has a long history of.............ummm, poor
environmental citizenship.
The three successor companies operate on split up parts of the original site. I believe Hexion continues on with the
production of hexamine. I believe Silar makes a polymer/plastic material that finds use in contact lenses and other
medical applications. I'm not sure what Oak Bark makes, but I think it would be not much different categorically from
the others — chemical intermediates for other products/processes.
Our interpretation of site conditions is that even in the areas where hexamine is not currently produced, there may be
residual amounts of hexamine widely distributed over the area. All three neighbor companies are being required to
monitor for hexamine. We have made all three permits identical in monitoring requirements - - this is a way to sort of
be sure that all three are responding to the pollutants discharged from their site, whether currently in their processes, or

whether just a legacy pollutant source from the old Wright Chemical operations. The permits have just been issued, and
we don't have the monitoring data (quarterly monitoring required) coming in, yet. I believe that there may be some
earlier hexamine data taken by the companies independent of the permit requirements, but we have not used that data
as a basis for any actions. Let us know if you have an interest in seeing hexamine data obtained under the permit, or
even the data obtained outside of the permit requirements.
It looks to me that after many years of frustration with this site, that we may have the right tools, and permittees willing
to respond more fully to environmental issues on the three sites - at least as far as pollutants transported by
stormwater runoff. This was a difficult site(s), and a difficult administrative assignment, and we're hopeful that we will
now see real improvement in the stormwater discharges from these sites.

Hi Ken,
You end summary is mostly correct. i wanted to mention the Y safety factor issue because there are a lot of common
misconceptions surrounding that. It isn't really a safety factor that we chose to include or not include but is a mandated
part of the federal equation for calculating an acute water quality standard. Without getting into details, basically a
Final Acute Value (FAV) is calculated based on the toxicity test data and then in most cases both the acute and chronic
water quality standards are calculated using this FAV. The acute water quality standard is always set at % of the FAV. So
since the benchmarks are essentially acute standards they will all be calculated as % of the FAV. So there is no option to
not include the safety factor.
Also just wanted to mention that regular benchmarks and LD benchmarks are calculated the exact same way -:we look
at all of the data and pick the most sensitive species to base the benchmark on (per our 213 rules - federal guidelines
require data from at least 8 specific families of aquatic life to be used in the calculation). We include the LD in cases
where we don't have much data to look at just to let the end user know what they are working with (a still defensible
but lower confidence benchmark).
One last question for you. Is anyone required to sample for hexamine now in their permits? Just curious to see if you
are getting any results back.
Thanks,
Nikki

Hi Ken,
It looks like your questions relate mostly to the use of the term LD. When the term LD is attached to a stormwater '
benchmark it means Limited Data (not lethal dose which is I think what caused the confusion). You_are correct that in:
general the Y: FAV is used as the stormwater benchmark. Y2 FAV is the same as an acute aquatic -life surface water - ,
standard (1/2 of the Final Acute Value is how an acute standard is calculated). Acute standards protect for short term
exposure to higher levels of a chemical and it was decided that this best mimicked potential stormwater exposures:
ok I get the point that a stormwater exposure, and hence our stormwater benchmark might be best approximated bra
short term acute exposure for aquatic life.) At this point we haven't found a good way to look at human health effects1n
stormwater since human health standards are calculated to protect for lifetime exposure to a pollutant and that isA'f
really expected for stormwater exposures. We do have a few exceptions to this but mostly benchmarks are based on`
the protection of aquatic life. ' '_44
Limited data (LD) is tagged onto a benchmark when there is very little aquatic life data available on which to calculate a
benchmark. In some cases we may only have one data point, which makes it hard to draw a conclusion on whether you
are looking at a very sensit've or insensitive species (therefore whether the resulting benchmark is over or under
protective). We like to flag these benchmarks so that they can be used with some caution. We generally recommend
that benchmarks with the LD tag be used more as a way to get an idea of potential toxicity (So, in this case with the
benchmark at 25,000 m L we might conclude that with the limited data in hand and depending on the concentrations
being discharged from our three permittees, there's no big red flag to make us concerned about an indication of toxicity,
et.) (for example to compare existing data to) but not as a strict regulatory limit. However, our 28 rules do allow us to
calculate water quality standards based on a single data point (in rule as the lowest LC50) if needed and they carry the
same regulatory weight as a 213 standard. We just like to identify these LD benchmarks (as well as the LD surface water
standards on our website) when they are based on limited data so that the end user is aware and can use discretion in
applying the value. (OK. So, this is very helpful for us as we think about future responses when/if one of our three
permittees exceeds their benchmark for hexamine. I think this stuff is pretty soluble, so even at 25,000 mgL it could all
be dissolved, I think. I could be wrong - once the stuff is in natural waters, but with high solubility it may not be a_
siltation threat ....but in salt water? This is beyond my water chemistry/aquatic biology knowledge.)
Hexamine is one of these Limited Data benchmarks. It is very high. We had data from two species available (fathead
minnow and daphnia). (Two common test species, right? But I take your point that with just these two, that's not a lot
of data and extrapolation to all species is not indicated. I wonder how many of our other stormwater benchmarks and
1 2FAVs are set on only these twospecies.) It appeared relatively non toxic to both species tested (at least at

concentrations you would think we would see in the environment). As a side note, we also have no human health
toxicity information available for this chemical. Feel free to let me know if I didn't completely address your question or
if anymore questions arise about hexamine or any benchmarks in general. Always happy to help!
Sow in answer to my on inal questions - LD means Limited Data, and. with such a limited data set, you probably picked
the higher secies indicator, and my guess is the value does not include any sort of % safety factor in the benchmark —
but you did flag it for us. Is that Pretty close?

Subject: RE: Benchmark for hexamine & Methanol
Hi Nikki,
Thanks for your help previously with stormwater benchmarks, ten has retrieved the correspondence below exchanged
last year on hexamine. In a meeting last week WIRO's supervisor, Rick Shiver, noted the high value for hexamine. He
really didn't make any more of it than just to note it. I'm curious about the notation LID and the hexamine benchmark.
I'd like to be somewhat prepared if the unasked question is raised again.
I'm highly ignorant of this part of our work. Specifically, I know nothing about the technical attributes or determination
of 'Lethal Dose', but would it be analogous to FAV? And if so, for stormwater permit benchmarks, would we want to
consider (%: LID) in order to be parallel with (% FAV) which we use for other pollutants? If you have you already covered
this ground with others in Stormwater Permitting, my apologies.
Is there something in the natures of the LID determination vs the FAV determination that argues for a %: safety factor
with one, but not the other?
Again, I'm sure my ignorance is getting in the way — my apologies. What don't I understand on this point?
Thanks for any response,
Ken

Jen,
Do you know what means Nikki's notation, `LD' for the hexamine value?

Hi Jen,
I checked our calculation sheets and those are both the right values for your benchmarks.
Hexamine: 25,000 mg/L LD
Methanol: 7700 mg/L

Hey Nikki,
I have a note in one of my files here that the benchmark for Hexamine is either 2500 or 25,000 mg/l. We have in our
files that the benchmark is 25,000 mg/I— I just wanted to make sure this is correct. Also the benchmark for methanol is
7,700 mg/I. I also wanted to check on this.
Thanks so much!

Questions for WiRO and DWQCO on Hexion:
1. What do you think about testing for EPA method 624 & 625? 1 don't think it looks necessary
based on what they have submitted — Linda/BG/BL—think anything different?
2. What do you think the turbidity benchmark should be? 50 or 25 NTUs based on lake or creek?
3. TRC: Thoughts? It is in WW permit but I can't see chlorine in mass quantities in the list of
chemicals but I could be mistaken.
4. Representative outfall status not granted due to terrible sampling record and lack of evidence
that it was ever granted and carving up of site.. Ok with that?
5. TKN, NO2+NO3, TN, NH3 ???
i. DO? DO: Lower cape fear has a TMDL for DO. This site also has many problems with
BOD, COD, N etc. and could contribute to many problems for DO.

4` Hello Ken,
Thanks for the info_ I'll call Hexion. I wouldn't mind inspecting the site again, \
I'd like to schedule during a week it appears we should be getting rain so that I can
have the opportunity to sample myself. I'm half tempted to haul a canoe down there
and launch it at their sampling platform (especially if it is raining with no
lightening) and c6l7—e-ct�samples in Livingston Creek. I'd like to establish the
impact to the receiving stream from their stormwater discharge. I'll call them to
discuss their submitting the stormwater permit. I will take the opportunity at that
time to ask them to send me a copy of their stormwater monitoring data since the
first of the year. I'd like to see whether the data has improved since their reign
out there. I'll let you know what they say. I'll call them today.

I Hi Linda,
a) In answer to your question in July, I'm not aware of any application received
from Titan, Essex, or STI, as of today in BIMS. We usually enter submittals into
BIMS within a couple of days of receiving them. So, I don't think we have one.
b) I'm thinking about contacting Hexion to expedite them as to submitting a
stormwater permit application. I believe our meeting was on January 9, 2007.
They have now got their wastewater permit from Susan and Ageyman, but I have not
had any communication or correspondence with Hexion or the consultant in probably
six months. l recall that they had to figure out how to split up the site for
stormwater c overage, or even if they wanted to split up the site between the two
companies. But I think 7 1/2 months is long enough for them to have acted. Any
developments that you're aware of wrt their stormwater discharges? Woul you
prefer for me to let you call them? I'm happy to do it.

All is well. Thanks for the heads up, I'm thinking these folks may be related
to Titan (or under another alias of Essex or STI) reason I say that is Todd
Walton with the port authority asked if they had submitted an application for a
stormwater permit with us. When asked what type of business they were in, he
said they had bought the Ideal Cement plant in Castle Hayne and was looking
into having an operation there at the port. Are you aware if an application
was reed for this facility (Titan, Essex or STI)?

Hey Ken; Thanks a bunch for the information. Looks like I need to dig a
little deeper to determine potential exposures. The permitted port area is
interesting. The location is 3330 River Road in Wilmington. Is that in an
area that has an umbrella type stormwater permit? The process will be
simpler if need only to comply with an existing permit.
Otherwise, it looks to me like unless they can move and transfer the cement
without any getting on the ground, an individual permit would be justified.
Let me know on the location and any existing permits as soon as you get a
chance. Thanks'. Tim Monroe - B&G

Tim,
I think we need a little more information as to the specific circumstances
at the site. I can make the following preliminary comments now, however.
a) We would not cover the discharges from this site under our general permit
NCG14. I think our perspective is that it is not close enough to a
ready -mixed concrete facility to be captured by that permit.
b) Based on the limited description we have so far, the site does appear to
be in the SIC Major Group 44 Water Transportation - - possibly as 4412,
4424, or 4449, depending on the specifics of operation.
c) While SIC 44 is required to have an NPDES stormwater permit by federal
rules at 40CFR122.26(b)(14)(viii), it is not captured in our general permit
for other transportation activities, NCG08. So, it's likely that we would
use an individual stormwater permit.
d) This would be consistent with our past practice of providing individual
stormwater permits for the handful of ports in North Carolina. We have
already permitted the ports to cover all activities within the port. Is
this site within a port boundary?
e) You note that vehicle washing will not be required. However, please be
aware that in addition to the SIC classification, 40CFR122.26(b) (14) (viii)
also establishes a secondary criterion of, ...which have vehicle
maintenance, equipment cleaning, or airport deicing operatoos." Please note
that the "equipment cleaning" qualification might be activated if, for
instance, the routine operation at the facility included periodic washdown
of the pad under the silos, or cleaning of other equipment. Further, an
additional subtlety may pertain here. While the site may be pulled into the
stormwater permitting program by washdown flows, those washdown flows are
themselves wastewaters, not stormwaters. As such, the washdown flows
themselves would require a wastewater permit from our NPDES wastewater
up -its. So, the site would require both an NPDES stormwater permit, and an

NPDES wastewater permit. Not at all an unusual circumstance.
f1 As to your last question about DWQ movement toward considering stormwater
flows from ready -mixed concrete facilities as wastewaters. I am not alert
to any such discussion within DWQ. However, we already consider commingled
flows as wastewaters. Only 'stormwater-only' flows are permitted as
stormwater. However, as you note, at a ready -mix facility, one permit
covers both types of discharges, but with different requirements.
Please call me with any questions, or if we need to discuss further. It may
be helpful to have the DWQ Regional Office participate in our discussion.
Where is this site located?

Subject: HE: Acute Toxicity Testing in SW - Hexion, Oak Bark, Silar
All
I like the idea of toxicity testing. I think it can demonstrate problems we wouldn't know were problems otherwise. Especially when some of our benchmarks for
individual chemicals f like hexamine) may be high, We have found that hexamine dissociates to free ammonia when in contact: with high pFl environment. So. .
toxicity testing would reveal issues that the individual benchmarks for chemicals (like hexamine), would not. Also, combinations of chemicals can produce more
toxic effects than what they do individually. Tox testing is really what we are after unless there is a WQ standard available. Going after toxicity benchmarks for
individual chemicals may not get us what we want, but tox testing would.
If the stormwater is toxic, it should no longer be considered stormwater, but a wastewater with toxic characteristics that should not be discharged without an
individual wastewater permit (that would require some type of treatment). With the tiers that are now in our stormwater permits, we allow the permittee a
timeframe (opportunity) to address the issue using 13MPs before it triggers further action by DWQ. So, the ? of whether BMPs can resolve the problem, we can
leave that up to the industry to investigate and implement before we take action. I wouldn't expect a tremendous number of tacilities with toxicity issues, but if
they are out there, we need to find them and deal with them on an individual basis.
Just my thoughts. And thanks for including me in the discussion. You all do a great job. Your permitting efforts are paying off in the quality of stormwater
discharges. I get to see the results of your permitting efforts since I inspect these facilities and I say, good job SW Permitting Unit, Bravo!

Matt — please correct me if I am wrong below...
Typically WW has a part in their Acute Tox language that asks for 5 samples if they have not sampled before to kind of get a baseline. "The permittee
shall conduct FIVE acute toxicity tests using protocols defined as definitive in E.P.A. Document EPA/600/4-90/027F entitled "Me ods or
Measuring the Acute 7'oxicit o E s to Freshwater and Marine Organisms." T he monitoring shall be performed as a Fathead Minnow
(Dime es promelas 24 hour static test... Samp ing an su en i-tg will occur on at least five occasions during the first year
following permit issuance. Outfall 024, 026, 004, 006, 027, 030 and 014 sampling shall occur during flue discharge events... After monitoring
of the first five toxicity tests, the permittee will conduct one test annually, with the annual period beginning in danuarg of the next calendar
year. "
When, before regular monitoring is Instituted they have a qualitative evaluation of the 5 data points. The NPDE:S unit then either a) asks for monitoring
with limits or b) asks for limits and then asks them to put in BMPs cj Sometimes they then ask for monitoring with just further monitoring — no limits?
We can either use acute test (24 hour) with Fathead Minnows or Daphnia — Daphnia is typically a bit more sensitive. Brian and I will call Cindy In the
lab to ask her her opinion and Matt is going to think more on this and get back to us.
We'll need to coordinate with the lab to see how this will effect their workload -- they will not process the test but will review the data.
As for the WHY... The BIG question. We need to think about why we want to do the acute tox. tests
• What will it tell us?
o I was thinking it would tell us If there were other constituents on site or if Hexamine or other chemicals on site are a problem.
Ok — so if we clean everything else up and there are no more COD, TSS, metals or N problems, and we find out they are still failing their acute tox test =
then what do we do? Make them put in BMPs?
o Would a storm water BMA solve an acute toxicity problem?
a What would we do if none of the other chemicals was causing the problem? Make them test for every chemical to find which ones were
causing It? This could be very expensive.
If Acute tox. Was failing and other parameters were also above benchmarks... would we do anything differently? I.e. make them have a pond?

• What if we do this all and nothing works? Send it to WW?
There's just a few happy question to think about... I'II propose a meeting time...
Have a good weekend!

SUPPLEMENT TO MONITORING, CONTROLS AND LIMITATIONS FOR
PERMITTED DISCHARGES
SPECIAL CONDITIONS
A (9.) ACUTE TOXICITY MONITORING Episodic (Outfalls 024, 026, 004, 006, 027, 030
and 014)
The permittee shall conduct FIVE acute toxicity tests using protocols defined as definitive in
E.P.A. Document EPA/600/4-90/027F entitled "Methods for Measuring the Acute Toxicity of
Effluents to Freshwater and Marine Organisms." The monitoring shall be performed as a
Fathead Minnow (Pimephales promelas) 24 hour static test. Effluent samples for self -
monitoring purposes must be obtained below all waste treatment. Sampling and subsequent
testing will occur on at least five occasions during the first year following permit issuance.
Outfall 024, 026, 004, 006, 027, 030 and 014 sampling shall occur during five discharge
events at the time of de-icing/anti-icing or during the next separate discharge event following
de-icing/anti-icing. After monitoring of the first five toxicity tests, the permittee will conduct
one test annually, with the annual period beginning in January of the next calendar year. The
annual test requirement must be performed and reported by June 30. If no discharge occurs
by June 30, notification will be made to the Division by this date. Toxicity testing will be
performed on the next discharge event for the annual test requirement.
The parameter code for this test is TAE6C. All toxicity testing results required as part of this
permit condition will be entered on the Monitoring Report Form for the month in which it was
performed, using the appropriate parameter code. Additionally, DWQ Form AT-1 (original) is to
be sent to the following address:
Attention: NC DENR / DWQ / Environmental Sciences Branch
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Test data shall be complete and accurate and include all supporting chemical/physical
measurements performed in association with the toxicity tests, as well as all dose/response
data. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should any test data from either these monitoring requirements or tests performed by the
North Carolina Division of Water Quality indicate potential impacts to the receiving stream,
this permit may be re -opened and modified to include alternate monitoring requirements or
limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid
test and will require immediate follow-up testing to be completed no later than the last day of
the month following the month of the initial monitoring.

Central Office Review Summary:
Facility discharges stormwater to Mill and Livingston Creeks. Neither of these waterbodies is listed on the 303(d)
list of impaired waters, and both have a swamp water classification. The Cape Fear Basinwide Plan doestot have
specific recommendations for individual S/W dischargers in this sub -basin. Low dissolved oxygen (DO) is as a
concern further downstream in the Cape Fear River Estuary and should be considered because this site also has
measured notably high BOD, COD, and ammonia levels in its stormwater discharges_
Since last renewal, the company noted but did not elaborate on these significant changes: constructed an additional
cooling tower, new hexamine warehouse, and milling operation building (all drain to outfaH 006). Also
constructed new pharmaceutical production building and several new storage tanks (as well as removed some from
service); not clear from the site map where these changes are located.

Analytical Monitoring: See attached Monitoring Data Analysis and summary submitted by company. Reviewer
recommends retaining_ WLmonitoring requirements because measured levels were extremely high for several
parameters, and because disc arge is to nu ent sensitive waters.
Between 40-90 percent of BOD samples at each outfall exceeded the benchmark value (30 mg/1), with average levels
approaching 150 mg/l. Between 70-100 percent of COD values were above the 120 mg/l benchmark, with average
levels between 300-1000 mg/l. Fifteen to 30 percent of TSS samples at each SDO were above 100 mg/l. Ammonia
and TKN values were above benchmark values in 45-I00 percent of the samples at each outfall, and NO3+NO2
levels exceeded 10 mg/l in all but one sample at outfalI 003 (although nitrates at 002 & 005 were usually below that
concentration). Formaldehyde values were also routinely higher than the current 0.49 mg/l benchmark (in 45-90
percent of samples at each outfall). Hexamine-values.._ Maximum values of BOD, COD, ammonia, TKN, and
and unacceptable as routine stormwater discharges. formaldehyde were all exceptionally high
Only two samples at one outfall exceeded the benchmark for lead. pH values were normally between 6-9 SU,
though one value at outfall 005 in 2004 was recorded as 10.3 (diii coi pa Iook..forsou oes??).
Monitoring frequency will remain quarterly for this permit. Because of the exceptionally high levels of BOD,
COD, nitrogen compounds, etc. and based on earlier recommendations from the Regional Office, monitoring more
frequent than semi-annual (what most renewals this term will have) is appropriate. Also, "cut-off concentrations"
have been replaced by benchmark values that will serve as a guide for the permittee to check the effectiveness of
BMPs and document efforts when necessary.
Most benchmarks are consistent_with t h d been "cut-off concentrations" in the permit; however, some differ.
r' Not sure where the ammonia cut-offo 2.0 /1 came from, but the benchmarkbased on acute effects (19.9 mg/1)

the Centra Office recommends representative outfall status not be continued upon renewal and will
specify that in the cover letter. The renewal permit will specify analytical monitoring should be performed at
each stormwater discharge outfall.
It should be noted that the wastewater permit for this facility (NC0003395) requires monitoring at outfalls 001 &
002. That petsrtit also requires the facility to monitor DO, temperature, and conductivity up- and downstream of

GENERAL DESCRIPTION OF AMINE
mine is a group of basic organic compounds derived from ammonia (NH3) by replacement
if one (primary amines), two (secondary amines), or three (tertiary amines) hydrogen atoms
iy alkyl, aryl groups or organic radicals. Amines, like ammonia, are weak bases because the
nshared electron pair of the nitrogen atom can form a coordinate bond with a proton,
,mines react with acids to give salts and with acid anhydrides (or ester) to form amides. They
aact with halogenoalkanes to form longer chains.

amines form diazonium salts with nitrous acid in cold solution in the presence of excess of
nineral acid. Or a diazoamine is obtained in absence of excess of acid. Other reactions are
condensation products with aldehydes; forming anilides; forming alkyl thioureas; yielding
sonitriles with alcoholic potash and chloroform. Tertiary amines combine with one molecular
)roportion of an alkyl iodide to form quaternary ammonium salts in which a central nitrogen
)tom is joined to four organic radicals and one acid radical. Quaternary ammonium salts are
ised as corrosion inhibitor, emulsifying and antiseptic agents. Aliphatic amines which have the
owest carbon content are water-soluble gases or liquids of low boiling point also readily solubl
n water in case of the next low carbon content. But aliphatic amines which have the high
-arbon content are odourless solids of high boiling point and are insoluble in water. They are all
uses and easily form salts with the mineral acids and double salts with the hologenoolkanes.
Nmine Salts are crystalline substances that are readily soluble in water. Many insoluble alkaloids
e.g. quinine and atropine) are used medicinally in the form of soluble salts. If alkali (sodium
iydroxide) is added to solutions of such salts the free amine is liberated. Short chain alkyl
)mines are used as raw materials of solvent, alkyl alkanolamines, and ingredients of rocket
uels. They are used to make other organic chemicals including rubber vulacanization
accelerators, pesticides, quaternary ammonium compounds, photographic chemicals,
corrosion inhibitors, explosives, dyes and pharmaceuticals. They are used in rayon and nylon
ndustry to improve the tensile strength. Allylamines are used as intermediates for ion exchange
esins, pharmaceuticals, water soluble polymers, herbicide softeners, rubber chemicals,
)olymerization initiators and cross -linking agents. Amines are used as reducing agents for the
ecovery of precious metals. They are versatile Intermediates. They have active applications in
)rganic synthesis for polymerization catalyst, chain extender in urethane coatings,
)grochemicals, pharmaceuticals, photographic, heat stabilizers, polymerization catalysts,
tame -retardants, blowing agents for plastics, explosives, and colorants. Long chain alkyl
)mines are used for the synthesis of organic chemicals and surfactants used as a corrosion
nhibitor, detergent, ore floating agent, fabric softener, anti -static agent, germicide,
nsecticide, emulsifier, dispersant, anti -caking agent, lubricant and water treatment agent.
kikyl tertiary Amines are used as fuel additives and preservatives. They have similar application
vith long chain alkyl amines. Hexomethylenediamine used in the manufacture of nylon-6,6 is
)repared by catalytic addition of hydrogen to nitriles. Aromatic amines also exist, such as
)henylamine, which are important for the production of diazonium salts. They dissociate in
voter (some very weakly). Aromatic amines are much weaker bases than the aliphatics. One
)f the most important aromatic amines is aniline; pale brown liquid boiling at 184 C, melting at
6 C. Aniline is obtained commercially from chlorobenzene by heating with ammonia in the
)resence of copper catalyst or from a product of coal tar (nitrobenzene) through the
eduction reaction. Aniline is the starting material in the dye manufacturing industry and as in
he manufacture of others, Aniline is converted into sulfanilic acid which is the parent
;ompound of the sulfa drugs. Aniline is also important in the manufacture of rubber -processing
;hemicals, antioxidants and varnishes. Amines take part in many kinds of chemical reactions

any amines are not only bases but also nucleophiles that form a variety of electrophile
)mpounds. They are important intermediates for chemical syntheses due to the basic
nctionality of the nitrogen atom and electrophilic substitution at nitrogen. Some examples of
)mpounds obtained by reaction of amines are:
• Amides (by reaction with acyl halides or ammonium carboxylate salts)
• N-Alkyl amines (by reaction with ha loge noalkanes)
• Isocyanates' (by reaction with phosgene)
• Carbamoyl chlorides or Urea derivatives (by reaction with phosgene)
• Alkoxylated amines (by reaction alkylene oxide)
• Quaternary ammonium compounds (by reaction with alkyl halides and dialkyl sulfates)
• N-Alkylcarbamic acids or N,N'- Dialkyl ureas (by reaction with carbon dioxide)
• Urea derivatives (by reaction with isocyanates)
• Schiff bases (by reaction'with aldehydes or ketones)
• Aminopropionitriles (by reaction of 10 and 20 amines with acrylonitrile)
• N-Alkyiamino acids (by reaction of 1 ° and 20 amines with monochloroacetic acid or with
unsaturated acids)
• Amine oxides. (by reaction of 30 amines with hydrogen peroxide)
• Sulfonamide derivatives (by reaction of 1 ° and 20 amines with benzenesulfonyl chloride)
)w molecular amine names are formed by adding '-amine' as a suffix to the name of the
arent compound. In substitutive nomenclature, the prefix 'amino-' is placed before the name
f the parent compound to denote the functional group in high molecular amines. Synthetic
mines are made mostly by reaction of alcohols with ammonia, catalyzed by metals( nickel or
opper) or metal oxide at high temperature. Many methods have been devised for the
mthesis of the amines; reacting ammonia with an alkyl halide and neutralizing the resulting
Ikyi ammonium salt with an alkali, e.g., sodium hydroxide. This procedure yields a mixture of
rimary, secondary, and tertiary amines that is easily separated into its three components by
octional distillation; boiling methyl isocyanate with caustic potash, heating the alkyl iodides
,ith ammonia; reduction of nitriles with alcohol and sodium; heating the esters of nitric acid
,ith alcoholic ammonia; reducing on nitro-poraffms; action of zinc and hydrochloric acid on
Idehyde ammonias; reduction of the phenylhydrazones and oximes of aldehydes and
Dtones with sodium amalgam in the presence of alcohol and sodium acetate; action of dilute
ydrochloric acid on the isonitriles; heating the mustard oils with a mineral acid, by the
Vdrolysis of the alkyl phthalimides. Primary amines contain the functional group -NH2 (called
mino group) and are converted into secondary and tertiary amines if heated with alkyl or aryl
dides. Primary amines form various oxidation products violently with concentrated nitric acid.

Silane - Wikipedia, the tree encyclopedia

Silane
From Wikipedia, the free encyclopedia.
Silane is a chemical compound with chemical formula Sil-14. It is the silicon
analogue of methane. At room temperature, silane is presumed to be a pyrophoric
gas — it spontaneously undergoes combustion in air without the need for external
ignition. However, there is a school ofthought which says that silane is stable and
that it is the natural formation of larger silanes during production which causes its
pyrophoricity. Above 420°C, silane decomposes into silicon and hydrogen; it can
therefore be used in the chemical vapor deposition of silicon.
More generally, a Silane is any silicon analogue of an alkanc hydrocarbon. Silanes
consist of a chain of silicon atoms covalenily bound to hydrogen atoms. The general
formula of a silane is SinH2n+2. Silanes lend to be less stable than their carbon
analogues because the Si -Si bond has a strength slightly lower than the C-C bond.
Oxygen decomposes silanes easily, because the silicon -oxygen bond is quite stable.
There exists a regular nomenclature for silanes. Each silane's name is the word
silane preceded by a numerical prefix (di, tri, tetra, etc.) for the number of silicon
atoms in the molecule. 'rhus Si2H6 is disilanc, Si3H8 is trisilane, and so forth. There
is no prefix for one; Sil-14 is simply silane. Silanes can also be names{ like any other
inorganic compound; in this naming system, silane is named silicon tetrahydride.
However, with longer silanes, this becomes cumbersome.
A cyclosilane is a silane in a ring, just as a cycloalkane is an alkane in a ring.
Branched silanes are possible. The radical Sit-13- is called silyl, Si21.15_ is disilanyl
etc. If we have trisilane with a silyl group attached to the middle silicon, we have
silyltrisilane. It parallels alkanes.
Silanes can also take the same functional groups as alkanes, 01-1 to make a silanol.
There is (at least in principle) a silicon analogue for all carbon alkanes.

Silane - Wikipedia, the free encyclopedia
http://en.wikipedia.orgtwikUSilane
Industrially, silane is produced from metallurgical grade silicon in a two-step
process. In the first step, powdered silicon is reacted with hydrochloric acid at about
300 °C to produce trichlorosilane, HSiC13, along with hydrogen gas, according to
the chemical equation:
Si + 3 HCI —► HSiC13 + H2
The trichlorosilane is then boiled on a resinous bed containing a catalyst which
promotes its disproportionation to silane and silicon tetrachloride according to the
chemical equation:
4 HSiCl3 —> SiH4 + 3 SiCl4
The most commonly used catalysts for this process are metal halides, particularly
aluminium chloride.

Several industrial and medical applications exist for silanes. For instance, silanes
are used as coupling agents to adhere glass fibers to a polymer matrix, stabilizing
the composite material. They can also be used to couple a bio-inert layer on a titanium implant. Other applications include water repellants, masonry
protection, control of graffiti, applying polycrystalline silicon layers on silicon wafers when manufacturing semiconductors, and sealants.

Stormwater and Whole Effluent Toxicity: Frequently Asked Questions
FAQ Note — The following are discussions of technical considerations of WET tests or possible
interpretations where required EPA methods are not specific on certain issues. Any deviations from defined
protocols should be discussed with, and approved by applicable regulatory agencies prior to
implementation. Modifications to EPA methods suggested here provide means to assess unique
circumstances often encountered in stormwater sampling.
I. What is meant by the terra "first flush" when referring to collection of stormwater samples?
"First flush" refers to the first waters released from a discharge point as a result of storm event or runoff
associated with ice and snow melt_ Typically, constituent concentrations are highest in this "first flush"
sample. "First flush" is operationally defined by a time -period in some states (e.g., waters discharged within
the first 15 or first 30 minutes of a discharge event). However, the "first flush" may not always contain the
highest concentrations of pollutants as this depends on the rain intensity, type of pollutant, and size of the
watershed. The first flush phenomenon is more prevalent for rains with relatively constant intensities and
small watershed size (Burton and Pitt, 2001). Therefore, it is important to understand the watershed in
order to determine if sampling of first flush in a storm event is critical. Another consideration is to capture
the first seasonal flush (e.g., after an extended dry period) in and areas.

a) Have agricultural, urban, and industrial runoff toxicity been assessed with WET tests? If so, what
toxicant(s) have been identified?
No examples are known of a regulatory entity using Whole Effluent Toxicity (WET) tests in a
compliance program for a discharge that consists only of stormwater (stormwater that comes into
contact with process materials is considered to be process water). However, toxicity testing is used
as a screening tool. (North Carolina has at least one example where stormwater runoff from airport
deicing collection ponds has an NPDES discharge permit with a WET limit).
Toxicity testing of stormwaters has been used as a monitoring tool for urban and agricultural
stormwater assessments in California Researchers have identified the pesticides diazinon and
chlorpyrifos in urban stormwaters (Katznelson and Mumley, 1997, Bailey et al., 2000; Larsen and
Perez, 2000; Fong et al., 2000, Larsen et al_, 2000; Larsen and List, 2002). Toxicity testing of
stormwaters from agricultural settings has identified rice pesticides, diazinon, chloryrifos, carbofuran,
and carbaryl as toxicants (SRWP, 1998; Foe et al., 1998: Reyes et al., 2000; Werner et al., 2000).
The Municipal and Industrial Strategy for Abatement (MISA) progtatn in Ontario, Canada, requires
control of stormwater discharges from industrial sites (OMOE, 1994). Discharges are required to
undertake a stormwater control study, which includes WET testing following Environment Canada
methods using rainbow trout and Daphnia magna (Environment Canada 2000a, 2000b). The MISA
program requires samples from at least four representative storm events (it is recommended that at least
one event be conducted during a spring thaw). Samples for toxicity are "first flush grab samples", which
are collected during the first 30-minutes of a storm. Only full strength (100%) stormwater is assessed for
toxicity.

b)_Are_acute,.andlor-chronic-test-methods)-being used to assess_stormw.aters?
Acute tests_(9.6.hours.or_less)a e primarily being used to initially assess the toxicity of stormwaters.
This is for several reasons, including the short-term nature of most storm events, the fact that
renewals may not be necessary (e.g., 48 hour non -renewal test), and the need to target and prioritize
survival impacts first.
c) Are there differences to consider when assessing continuous effluent discharges (e.g., POM vs.
storm drain discharges that occur only when sufficient runoff is generated?
Yes. As discussed above, a relatively short test duration may be chosen to reflect the duration of
exposure typically observed for stormwater discharges in contrast to longer durations that may exist for
continuous discharges. Another concern includes consideration of the receiving stream organisms. Some
receiving streams may rarely contain water, while others may be marine or estuarine in nature. The
appropriate test organism and associated procedures would be a consideration in such cases (for
example, initiation of a test with a "first flush" sample, and renewal with subsequently collected
samples). Test conditions should also consider actual exposure duration, and logistical constraints (e.g.,
short -duration rain events that may not allow adequate sample collection). The general water chemistry
conditions of the stormwater runoff discharge may also be of concern. The pH of rainwater is naturally
acidic, and many stormwater runoff discharges will have pH conditions that do not fall within the
recommended range for WET tests (generally 6.0 to 9.0 sm. but 6.5 to 8.5 s.u. in some states).
Stormwater discharges may also be very low in hardness, alkalinity, and dissolved solids.
d) Is capturing the first flush important?,.,..
It is not known whether this phenomenon has been studied relative to WET.
However, the precedent set for chemical -specific stormwater sampling, to sample first -flush
discharges, suggests the potential for higher chemical -specific toxicity in first -flush samples. This
"first flush" effect depends on the nature and form of the pollutant (Ward and Elliot, 1995). The
chemograph peak slightly precedes that of the hydrograph for sediments or sediment -bound
pollutants (e.g., chlorpyrifos, phosphorus) entrained in the water column. However, for dissolved
pollutants like diazinon, the chemograph peak follows that of the hydrograph.
3. How are stormwaters with extreme ranges ofpH, dissolved oxygen (DO), conductivity and/or
hardness evaluated for WET when these parameters are not within the ranges needed far conducting
the standard toxicity test method?
The EPA protocols for warmwater organisms (EPA-821-R-02-012) require a DO concentration between 4.0
mg/L and saturation. Gentle aeration is applied until the DO concentration is within the required range if
DO values do not meet these specifications. EPA acute protocols also specify that test solution pH outside
of the range of 6.0 to 9.0 s.u. may cause toxicity, and the only way to determine whether any toxic effects
observed are due to pH is to run pH -adjusted tests in parallel with unadjusted tests. Sample pH is adjusted to
7.0 s.u. with 1 N NaOH or 1 N HCl if acceptable pH conditions are not present in freshwater tests.
Conductivity and hardness of a stormwater sample should not be adjusted prior to testing according to
EPA's WET test protocols. However, the investigator may wish to run additional test treatments where
hardness has been adjusted to levels used in dilution and/or receiving waters, depending on the purpose of
the tests.
4. Are single concentrations (100% stormwater, for example) compared to a control in WET
2 of 5 1/12/2006 2:00 PN

Stormwater related WET FAQs

stormwater tests or are multiple dilutions of the stormwater tested?
Either testing approach may be applied. depending on the purpose of the testing and the discharge setting.
For example, if the receiving stream is small and stormwater-dominated during storm events, "screening"
tests of undiluted stormwater discharges may be appropriate. Multiple -dilution WET tests would be
required, so that well-defined LC50 values could be obtained, if the goal of the testing program is to
quantify the toxic magnitude of stormwater discharges. The in -stream concentration of the discharge must
be known in order to determine the potential effect of a stormwater discharge on a receiving stream.
Multiple -dilution tests, necessary to develop a defined LC50 value, would have to be conducted for
comparison to the in -stream waste concentration in order to make this assessment. The duration of the
rainfall and discharge event would also have to be considered in order to properly assess possible effects.
5. When would a multiple dilution test be performed if a single concentration test is initially conducted?
A single concentration is typically compared to a control to determine the effect in 100% stormwater
exposures as a first tier to assess stormwaters. A multiple concentration test should be considered for the
next sampling event if there is a high percent effect (e.g., 100% mortality within 24 hours). It is
recommended that the multiple dilution test be conducted initially given the holding time requirement for
WET testing (initial use of samples must be within 36 hours of sample collection).
6. Is adherence to the 36 hours holding requirement necessary?
All tests should be conducted as soon as possible following sample collection. EPA has allowed
exceptions to the 36-hr holding time, for example, when effluents are shipped overseas for testing (EPA,
1996). The primary reason for an extension of the holding time would be the consideration of the
sampling and laboratory technicians safety (Burton and Pitt, 2001; see page 255), and logistics of
coordinating collection and transport of multiple stormwater samples within a short period of time.
Therefore, it is encouraged that the 36-hour holding time for test initiation be targeted. No more than 72
hours should elapse before initial use of a sample (EPA, 1993).
7. How can the standard test renewal practices specified in the testing manuals be followed given that
storm events may be of short duration?
EPA acute test protocols specify that test solutions be renewed after 48 hours for a 96-hour test. A more
realistic option, in cases when a second stormwater sample may not be available, would be to renew the
test solutions with a mixture of ambient waters and stormwaters if such waters could be collected
following test initiation while meeting WET test holding time specifications (Katznelson and Mumley,
1997). In most states, the test solution is not renewed in shorter -duration acute tests (e.g., 48-hour).
8. Is timing of sample collection to a flow measurement important?
A measurement of flow should coincide with the collection of stormwater samples for WET testing. This
typically entails measuring flow discharge from the site, in addition to the amount of rainfall causing the
discharge event. It is important to establish when sampling occurred relative to the streamflow hydrograph
(and subsequent chemograph) (Ward and Elliot, 1995). Scientists must consider the magnitude of toxic
response in relation to flow of receiving waters when making chemical or toxicity assessments of receiving
or stormwaters in the regulatory arena (permitting and TMDL development) and when developing study
designs (Denton, 2001). Therefore, if assessment and quantification of the mass loadings are of interest,
then concurrent flow measurements from a US Geological Survey gaging station located near the point of
interest and within the same watershed should be collected (USGS, 1999; USGS 2000). Measurement of
flow concurrent with sample collection should be considered if a nearby and representative gauging station

17.2 Use Support Assessment Summary
Use support ratings were assigned for waters in subbasin 03-06-17 in the aquatic life, recreation,
fish consumption and water supply categories. All waters are Impaired on an evaluated basis in
the fish consumption category because of fish consumption advice that applies to the entire
basin. In the water supply category, all WS classified waters (1.6 miles) are Supporting on an
evaluated basis based on reports from DEH regional water treatment plant consultants. Refer to
Appendix X for a complete list of monitored waters and more information on Supporting
monitored waters.
In the aquatic life category 97.8 stream miles (31.2 percent), 407.0 freshwater acres (32.5
percent) and 20,592.0 estuarine acres (87.8 percent) were monitored during this assessment
period. There were 6,457.0 estuarine acres (27.5 percent) identified as Impaired in this category.
In the recreation category 16,404.7 estuarine acres (70.0 percent), 44.1 freshwater miles (14.1
percent), and 10.3 coastline miles (45.2 percent) were monitored during the assessment period.
There were 96.6 estuarine acres (<1 percent) and 4.7 coastline miles (20.6 percent) identified as
Impaired in this category.
In the shellfish harvesting category 8,286.1 estuarine acres (100.0 percent) were monitored
during the assessment period. There were 2,061.6 estuarine acres (24.8 percent) identified as
Impaired in this category.
17.3 Status and Recommendations of Previously and Newly Impaired
Waters
The following waters were either identified as Impaired in the previous basin plan (2000) or are
newly Impaired based on recent data. If previously identified as Impaired, the water will either
remain on the state's 303(d) list or will be delisted based on recent data showing water quality
improvements. If the water is newly Impaired, it will likely be placed on the 2006 303(d) list.
The current status and recommendations for addressing these waters are presented below, and
each is identified by an assessment unit number -(AU#)_ Refer to the overview for more
information on AUs. Information regarding 303(d) listing and reporting methodology is
presented in Appendix VII.
For Impaired Class SA waters presented below refer to Chapter 27 for more information and
recommendations on shellfish harvesting use support. All waters identified as Impaired in the
shellfish harvesting category will be added to the 303(d) list of Impaired waters. TMDLs
(Chapter 35) will be developed for identified stressors within 8-I3 years of listing.
173.1 Atlantic Ocean [99-(2) and (3)b[
Current Status
These segments of the Atlantic Ocean were not individually identified in the 2000 basin plan,
and no specific recommendations were made in the 2000 basin plan.
DRAFT Chapter 17 — Cape Fear River Subbasin 03-06-17 180

The Atlantic Ocean [99-(3)b] from the subbasin boundary to South Fort Fisher Boulevard (4.7
coastline miles) is Impaired for recreation because of permanent postings of swimming
advisories and the 18 known storm drains that periodically discharge onto the beach in this
segment. Segment 99-(2) is Not Rated for recreation because of the presence of storm drains that
periodically discharge into these waters although no criteria were exceeded at sites S-14 and S-
15.
17.3.2 Bald Head Creek [AU# 18-88-8-41
Current Status
Bald Head Creek, from source to the Cape Fear River (79.9 acres) is Impaired for shellfish
harvesting because this segment is classified by DEH SS (Chapter 27) as prohibited in growing
area B-2. Bald Head Creek will be added to the 303(d) list of Impaired waters.
17.3.3 Beaverdam Creek [AU# 18-88-9-1-(0.5) and (1.5)1
Current Status
Beaverdam Creek [18-88-9-1-(0.5)], from source to Polly Gully Creek (3.0 miles), is Not Rated
for aquatic life because benthic community ratings could not be assigned at sites BB 17, BB39
and BB204 in 1999. The watershed was studied in 1999 to evaluate the effects of ditching
associated with the St. James Plantation development. Large amounts of silt in the creek
promoted a shift toward silt tolerant species. The Brunswick WTP discharge provided
permanent flow and increased the pH of the stream above what would be natural for streams in
this area. A surprisingly intolerant benthic community was present in some areas of the
watershed.
Beaverdam Creek [18-88-9-1-(1.5)], from Polly Gully Creek to ICWW (11.3 acres) is Impaired
for shellfish harvesting because this segment is classified by DEH SS (Chapter 27) as prohibited
in growing area B-1.
2005 Recommendations
DWQ will continue to monitor Beaverdam Creek. It is recommended that further development
in this area avoid ditching and use BMPs to prevent further siltiation of streams in this
watershed. Segment 18-88-9-1-(1.5) will be added to the 303(d) list of Impaired waters.
17.3.4 Cape Fear River Estuary
Brunswick River [AU#18-77]
Cape Fear River [AU#18-(63)a and b, (71)a and (71)b]
Cape Fear River [AU#18-(87.5)a, c and d]
2000 Recommendations
The 2000 basinwide plan recommended that a TMDL be developed for dissolved oxygen and
that the TMDL be used to guide wasteload allocations for new and expanding discharges. Refer
to Chapter 30 for information on NPDES permitting.
Current Status
The Cape Fear River [18-(63)a], from International Paper intake to Bryant Mill Creek (3.8
miles), is Impaired on a monitored basis in the fish consumption category.
DRAFT Chapter 17 — Cape Fear River Subbasin 03-06-17 181

The Cape Fear River [18-(63)b], from Bryant Mill Creek to Toomers Creek (18.5 miles), is Not
Rated because dissolved oxygen was below 4 mg/l in 11.0 and 13.8 of samples collect at sites
BA640 and BA639. Also. BASF (NC0059234) had significant violations of biological oxygen
demand permit limits and Leland Industrial Park W WTP (NC0065676) had significant violations
of total suspended solids permit limits during the last two years of the assessment period. BASF
is under a special order of consent (SOC# S0314) that expires in August 2005.
The Cape Fear River [ 18-(71)a], from Toomers Creek to Snows Cut (5,616.7 acres), is Impaired
for aquatic life because the dissolved oxygen standard was violated in 42.9, 37.1, 16.4, 29.5, 23.2
and 10.4 percent of samples collected at sites BA642, BA644, BA708, BA709, BA713 and
BA716. The dissolved oxygen standard for SC waters is 5mg/l. The pH standard was also
violated in 38.5, 37.1, 10.4. 20.5 and 19.6 percent of samples at the same sites. The low pH may
be associated with swamp drainage from the Black and Northeast Cape Fear River. The segment
of the Cape Fear River upstream of this area has a supplemental classification of Sw that
acknowledges that swamp streams may have lower dissolved oxygen and pH.
The Brunswick River [ 18-77], from source to the Cape Fear River (743.7 acres), is Impaired for
aquatic life because the dissolved oxygen standard was violated in 14.3 percent of samples at site
BA707. The dissolved oxygen standard for SC classified waters is 5 mg/l. The pH standard was
also violated in 19.6 percent of samples. The low pH may be associated with swamp drainage
from the Black and Northeast Cape Fear River. Clairmont Shopping Center (NC0058599) had
significant violations of ammonia permit limits during the last two years of the assessment period
as well.
The Cape Fear River [ 18-(71)b], from Snows Cut to Federal Marsh (7,856.7 acres), is Supporting
aquatic life because no criteria were exceeded at site BA722 although Kure Beach WWTP
(NC0025763) had significant violations of total suspended solids permit limits during the last
two years of the assessment period.
The Cape Fear River [I 8-(87.5)a, c and d], from Polly Gully Creek to IC W W (11.3 acres) is
Impaired for shellfish harvesting because these segments are classified by DEH SS (Chapter 27)
as prohibited in growing areas 13-1 and B-4. Segment 18-(87.5)a is Supporting aquatic life and
recreation because no criteria were exceeded at sites BA722 and S43. Segment 18-(87.5)b is
Supporting shellfish harvesting and aquatic life because this area is approved and no criteria
were exceeded at site BA734.
2005 Recommendations
DWQ, with the Lower Cape Fear River Program (Appendix V) are developing a TMDL to
address the low dissolved oxygen in these segments. TMDL targets and allocations will be
addressed as part of the process. Modeling efforts will include a watershed model of the
Northeast Cape Fear River and hydrodynamic and water quality modeling of the estuary. The
TMDL is scheduled to be submitted to EPA in late 2005. Until the TMDL is approved by EPA,
new and expanding discharges will be carefully considered on a case -by -case basis. The NPDES
compliance process will be used to address the significant permit violations noted above. Refer
to Chapter 30 for information on NPDES permitting and Chapter 37 for information on the
modeling and monitoring efforts.
DRAFT Chapter 17— Cape Fear River Subbasin 03-06-17 182

Segments 18-(71)a and 18-77 will remain on the 303(d) list of Impaired waters replacing the
Cape Fear (DEH Area) B 10 listing. Segments 18-(63)a and 18-(87.5)a, c and d will be added to
the list.
17.3.5 Coward Creek [AU# 18-88-9-2-5-1]
Current Status
Coward Creek, from source to the Cape Fear River (5.9 acres) is Impaired for shellfish
harvesting because this segment is classified by DEH SS (Chapter 27) as prohibited in growing

17.3.6 Dennis Creek [AU# 18-88-9-2-31 and Piney Point Creek [AU# 18-88-9-2-4]
Current Status
Dennis Creek and Piney Point Creek south of the ICWW (45.7 acres) are Impaired for shellfish
harvesting because these segments are classified by DEH SS (Chapter 27) as prohibited in
growing area B-l. These creeks will be added to the 303(d) list of Impaired waters.
17.3.7 Dutchman Creek [AU# 18-88-9-3-(2.5)], Dutchman Creek Outlet Channel [AU#
18-88-9-3-31, and Dutchman Creek Shellfish Area [AU# 18-88-9-3-(4)1
Current Status
Dutchman Creek, the Outlet Channel and Shellfish Area north of the ICWW (192.0 acres) are
Impaired for shellfish harvesting, because these segments are classified by DEH SS (Chapter 27)
as prohibited in growing area 13-1. These creeks will be added to the 303(d) list of Impaired
waters.
17.3.8 Elizabeth River [AU# 18-88-9-2-(1)1, Elizabeth River Shellfishing Area [AU# 18-
88-9-2-(2)] and Molasses Creek Shellfish Area [AU# 18-88-9-2-5]
Current Status

Fishing Creek will be added to the 303(d) list of Impaired waters.
DRAFT Chapter 17 —Cape Fear River Subbasin 03-06-17 183

17.3.10 Intracoastal Waterway (ICWW) [AU#18-88-9a and b]
2000 Recommendations
This segment of the ICWW was not individually identified in the 2000 basin plan, but was
considered Not Supporting because if was closed to shellfish harvesting. No specific
recommendations were made in the 2000 basin plan.
Current Status
The Intracoastal Waterway [ 18-88-9a], from channel marker F 1 to Dutchmans Creek Outlet
Channel (226.6 acres) is Impaired for shellfish harvesting because this segment is classified by
DEH SS (Chapter 27) as prohibited in growing area 13-1. This segment is Supporting recreation
because no criteria were exceeded at site S-41.
The Intracoastal Waterway [I 8-88-9a], from Dutchmans Creek Outlet Channel to Cottage Creek
is Impaired for aquatic life because the dissolved oxygen standard was violated in 11.1 percent of
samples at site BA740. The dissolved oxygen standard for SC classified waters is 5 mg/l. This
segment is also Impaired for shellfish harvesting and recreation because this segment is
classified by DEH SS (Chapter 27) as prohibited in growing area B-1 and because of permanent
swimming advisories at site S42.
2005 Recommendations
DWQ and DEH will continue to monitor the ICWW and work with local governments to identify
sources of bacteria and oxygen consuming materials. This segment of the ICWW will be added
to the 303(d) list of Impaired waters. TMDLs (Chapter 35) will be developed for identified
stressors within 8-13 years of listing.
l 7.3.11 Town Creek [AU# 18-81 ]
Current Status and 2005 Recommendations
Town Creek, from source to the Cape Fear River (32.1 miles), is Supporting aquatic life because
of a natural benthic community rating at site BB 13. A sample in November 1999, after three
hurricanes, indicated the benthic community was not severely impacted by the storms. Town
Creek is Impaired on a monitored basis in the fish consumption category and will be added to the
303(d) list of Impaired waters.
Water Quality Initiatives
In 2000. the NC Coastal Land Trust (Chapter 34) received a $305,000 CWMTF (Chapter 34)
grant to acquire 260 acres conservation easements along Town Creek_ There was also an
additional 320 acres of donated conservation easements included in the project. In 2001, the NC
Coastal Land Trust received a $277,000 CWMTF grant to acquire 115 acres conservation
easements along Town and Russell Creeks. There was also an additional 135 acres of donated
conservation easements included in the project. in 2002, the NC Coastal Land Trust received a
$2,095,000 CWMTF grant to acquire 638 acres along Town Creek_
DRAFT Chapter 17 — Cape Fear River Subbasin 03-06-17 184

17.4 Status and Recommendations for Waters with Noted Impacts
The surface waters discussed in this section are not Impaired. However, notable water quality
problems and concerns have been documented for some waters based on this assessment_ While
these waters are not impaired, attention and resources should be focused on these waters to
prevent additional degradation or facilitate water quality improvement. Waters in the following
section are identified by assessment unit number (AU#). See overview for more information on
AU#s.
17.41 Greenfield Lake JAU# 18-88-3.51
Current Status and 2005 Recommendations
Greenfield Lake (75.3 acres) is Supporting aquatic life because no criteria were exceeded during
lakes monitoring in summer 2003. The lake has problems with aquatic weeds. In 2003, almost
75 percent of the surface was covered with aquatic weeds.
17.4.2 Southport Restricted Area IAU# 18-88-3.51
Current Status and 2005 Recommendations
The Southport Restricted Area, on the west bank of the Cape Fear River from Price Creek to
Southport (715.3 acres), is Not Rated for aquatic life on an evaluated basis because the ADM
Southport Plant (NC0027065) had significant violations of total settable solids permit limits
during the last two years of the assessment period that could have negatively impacted aquatic
life. The NPDES compliance process will be used to address the significant permit violations
noted above.
DRAFT Chapter 17 — Cape Fear River Subbasin 03-06-17 185

Chapter 35
TMDLs in the Cape Fear River Basin
35.1 Introduction to TMDLs
A TMDL or Total Maximum Daily Load is a calculation of the maximum amount of a pollutant
that a waterbodv can receive and still meet water quality standards, and an allocation of that
amount to the pollutant sources. A TMDL is the sutra of the allowable loads of a single pollutant
from all contributing point and nonpoint sources. The calculation must include a margin of
safety to ensure that the waterbody can be used for the purposes the State had designated. The
calculation must also account for seasonal variation and critical conditions in water quality.
For each water quality limited segment Impaired by a pollutant and identified in the 303(d) list. a
TMDL must be developed. TMDLs are not required for waters Impaired by dam operations. A
TMDL includes a water quality assessment that provides the scientific foundation for an
implementation plan_ An implementation plan outlines the steps necessary to reduce pollutant
Ioads in a certain body of water to restore and maintain human uses or aquatic life. For more
information on TMDLs and the 303(d) listing process, refer to Appendix VII or visit the TMDL
website at http://h2o.enr.state.nc.us/tmdl/
35.2 Approved TMDLs in the Cape Fear River Basin
The following TMDLs have been completed and approved by EPA (Table 38). Refer to the
subbasin chapters for specific reductions called for in the TMDLs and to determine what local
governments may be affected by TMDLs.

(Chapter 8). a turbidity TMDL for Third Fork Creek (Chapter 5), a chlorophyll a TMDL for
DR4FT Chapter 35 — TWDLs in the Cape Fear River Basin

Jordan Reservoir (Chapter 36), and a dissolved oxygen TMDL for the Cape Fear Estuary
(Chapter 37).
Two large TMDL efforts underway in the Cape Fear River Basin include the Jordan Reservoir
Chlorophyll a TMDL and the Cape Fear Estuary Dissolved Oxygen TMDL. Information
regarding water quality data and assessment for Jordan Reservoir is discussed in Chapter 5,
while TMDL information in discussed in Chapter 36. Information regarding water quality data
and assessment for the Cape Fear Estuary is discussed in Chapter 17, while TMDL information
is discussed in Chapter 37.
35.3 Scheduled TNWLs in the Cape River Basin
EPA guidance provides a timeline for TMDL development of 8 to 13 years. Thus, the elapsed
time between 303(d) listing and TMDL development should not exceed 8 to 13 years. if the
pace of TMDL development does not comply with this schedule, EPA may elect to develop
TMDLs in order to meet this timeline. Waterbodies that were listed in 1998 should have
TMDLs developed by 2006 to 2011.
35.4 TMDL Implementation Efforts
Point source (i.e., wastewater) implementation plans are included in TMDLs per EPA guidance.
Thus, any point source discharging to an Impaired water will receive an explicit allocation within
the TMDL. In some cases, the allocation may be equal to existing permit limits, thus no action is
needed by the wastewater permittee. In other cases, the allocation may be associated with a
reduction in loading. Where applicable, the point source allocation may include provisions for
bubble permits and point-to-point trading.
Nonpoint source implementation plans are not included in TMDLs, nor are they required by
federal law. Nonpoint source implementation plans can be developed by DWQ, other agencies
within DENR, COGS, or local government offices. For example, the Piedmont Triad Council of
Governments (PTCOG) obtained Section 319 grants to develop implementation plans for Little
Troublesome Creek and Town Branch_ Each of these TMDLs has only nonpoint source loadings
contributing to impairment.
EPA has provided guidance regarding TMDLs and NPDES stormwater permits. As a result,
selected NPDES stormwater permits may contain additional language when subject to a TMDL.
Per EPA, MS4s identified in TMDLs as contributors to impairment may be required to develop a
management plan that includes additional monitoring and BMP installation associated with
pollutants of concern.
35.5 Impaired Waters Update
Waters identified as Impaired during this assessment period will be updated in the 2006
Integrated Report. These waters will be considered Impaired upon EMC approval of this basin
plan. TMDLs will be scheduled as appropriate depending upon the classification of the
waterbody and the identified problem parameters.

1.0 GEOSYNTHETIC INSTALLATION
1.1 Anchor Trench Systems
All Anchor Trench Systems shall be excavated by the Earthwork Contractor (unless otherwise
specified) in accordance with the lines and widths shown on the contract drawings, prior to
geosynthetic placement.
If the anchor trench is excavated in clay susceptible to desiccation, no more than the amount of
trench required for the geosynthetics to be anchored in one (1) day will be excavated (unless
otherwise specified) to minimize desiccation potential of the anchor trench clay soils.
The corners of the trench where the geosynthetics enter the trench should be slightly rounded to
avoid sharp bends in the geosynthetic& No large rocks or clay lumps will be allowed to underlie
the geosynthetics in the anchor trench
Baclfilling of the anchor trench will be conducted in accordance with Section 1.5.
1.2 Geosynthetic Placement
Immediately prior to installation of any geosynthetics, the surface will be inspected by Agru
America, Inc. and the owner or the owner's representative. The decision to repair cracks, if any,
will be made only by the owner's representative. The subgrade will be walked by Agru America,
Inc. and the Project Manager for joint approval. Agru America, Inc. will sign acceptance of the
surface condition of the subgrade. The integrity of the underlying soil is the responsibility of the
owner/earth work contractor.
Subgrade Preparation Recommendations
No geosynthetics will be placed on surfaces not previously found acceptable by the Agru
America, Inc. supervisor or his agent_
No sharp stones or other hard objects that could penetrate the geosynthetics will be present in the
top i inch (1 ") (2.5 cm) of the surfaces to be covered.
Surfaces to be lined shall be smooth and free of all rocks, sharp stones, sticks, roots, and sharp
objects, or debris of any kind. The surface should provide a firm, unyielding foundation for the
geosynthetic with no sudden, sharp or abrupt changes or break in grade.
1.2.A Geomembrane Placement
1.2.A.1 Installation Schedule
Field panels are placed only after the subgrade has been accepted by Agru America, Inc. and the
Project Manager. Agru America, Inc. takes responsibility only for accepting the surface conditions
of the subgrade.
Field panels are placed one at a time, and each field panel will be seamed immediately after its
placement.

1.2.A.2 Location
Field panels are located by the Agru/America, Inc. Field Supervisor in a manner consistent with
the specifications and in a manner best suited to existing site conditions (i_e., a field panel is a roll
or a portion of roll cut in the field).
At the time of installation, the Agru America, Inc. Field Supervisor will give each field panel an
"identification code" (alpha or alphanumeric). This identification code will be agreed upon by the
Reject Manager. This field panel identification code will be as simple and logical as possible.
Agru America, Inc. will record the identification code, roll number, and date of installation of
each geomembrane field on the Daily Progress Report. Daily Progress Reports are to be
submitted to project manager the day following production or as agreed upon prior to installation.
1.2.A.3 Field Panel Identification
A field panel is the unit area of geomembrane that is to be seamed in the field.
At the time of installation, Agru America Inc.'s Supervisor will give each field panel an
"identification code" (alpha or alphanumeric). This identification code will be agreed upon by the
Project Manager. This field panel identification code will be as simple and logical as possible.
Agru America, Inc. will record the identification code, roll number, and date ofinstalMon of
each geomembrane field on the Daily Progress Report. Daily Progress Reports are to be
submitted to project manager the day following production or as agreed upon prior to installation.
1.2.A.4 Weather Conditions
Neither welding nor placement of geomerribzane will take place during any precipitation, in the
presence of excessive moisture, blowing dust, in the presence of high winds, or in areas of
standing water, unless necessary precautions can be taken.
1.2.A.5 Method of Placement
Agra America, Inc. will verify the following:
0 Any equipment used does not damage the geomembrane by handling, trafficking, excessive
heat, or other means;
0 The prepared surface underlying the geomembrane has not deteriorated since previous
acceptance and is still acceptable immediately before geosynthetic placement;
0 Construction equipment used to deploy geomembrane should not create excessive rutting in
the subgrade;
0 The method used to place the panels minimizes wrinkles (especially differential wrinkles
between adjacent panels);

0 If the substrata is a geosynthetic material, deployment may be by hand, by use of small jack
lifts on pneumatic Hires having low ground contact pressure, or by use of all -terrain vehicles
(ATVs) having low groin contact pressure;
0 Any geosynthetic elements immediately underlying the geomembrane are clean and free of
debris;
0 No personnel working on the geomembrane will smoke, wear damaging shoes, or engage in
other activities that could damage the geomembrane;
0 The method used to unroll the panels does not cause scratches or crimps in the geomembrane
and does not damage the supporting soil;
0 Adequate temporary loading and/or anchoring (e.g., sand bags, tires), not Rely to damage the
geomembrane, bas been placed to prevent uplift by wind (in case of high winds, continuous
loading, e.g., by adjacent sand bags, or so id is recommended along edges of panels to minimize
risk of wind flow under the panels);
0 Direct contact with the geomembrane is mid; i.e., the geosynthetic(s) are protected by
geotextiles, extra geomembrane, or other suitable materials in areas where excessive traffic
may be expected;
0 In the case of high density conductive geomembrane, the electrically conductive layer should
be placed conductive side down, and;
0 Agru America, Inc. shall inform the Project Manager if the above conditions are not fulfilled.
1.2.A.6 Damage
Agru America, Inc. will inspect each geosynthetic after placement and geor ernbrane prior to
seaming for damage. Agru America, Inc. will advise the Project Manager which panel or portions
of panels should be repaired as required Damaged panels or portions of damaged panels that have
been rejected will be marked and their removal from the work area recorded by Agru America,
Inc_ Repairs to geode will be made according to procedures described in Section 1.4.A2.
L2.B Geotextile and Geonet Placement
Geotextile and geonets will be handled in such a manner as to ensure they are not damaged in any
way -
On slopes, geotextides and geonets will be anchored in the anchor trench; then rolled down the
slope in such a manner as to continually keep the material in tension.
In the presence of wind., the materials will be weighted with sandbags until final covers are

Care will be taken to assure that any underlying layers are not damaged during placement of
geotextiles and geonets.
Care will be taken to assure that stones, mud and dirt and not entrapped in the geotextile and
geonet during placement and seaming operations.
Cutting and trimming of product placed on top of the liner must be done with hooked blade
knives.
1.2.0 Geosynthetic Clay Leiner (GCL) Placement
The geosynthetic clay liner must be installed in general accordance with the manufacturer's
specification and in such a way as to prevent any damage to the GCL.
One method of installing a GCL is to utilize a piece of equipment such as a front-end loader or
forklift that is capable of lifting the GCL. A spreader bar is attached to the lifting equipment, and
a core bar is installed through the GCL core. Straps or other types of attachments are looped over
the core bar and the spreader bar. The equipment then lifts the GCL above the subgrade soils and
while backing away from the initial starting point unrolls the GCL roll- This method can be used
to install a membrane -backed GCL with the bentonite side up or side down.
For GCL's with a geomembrane backing, an alternate method for installing the GCL with the
membrane facing against the soil is to attach a ten foot (10) 3m) long bar clamp to the end of the
roll. The upper clamp has a chain attachment that can easily fit over a trailer hitch that is on a
truck or other type of equipment. The GCL is then pulled across the subgrade soils. If the
membrane is textured, then rub sheets should be used_
Folds in the GCL must be "stretched out" prior to installation of any overlying geosynthetics or
soils. If these folds cannot be removed by rent of the GCL, then these folds in be "cut"
from the GCL and patched according to the manufacturer's specifications.
1.3 Geosynthetic Seaming and Joining
1.3.A Geomembrane Seaming
See Section 2.0 for more guidance.
1.3.A.1 Seam Layout
Seams will be made by overlapping adjacent sheets approximately three inches (3") (7.5 cm) for
extrusion welding and approximately four to six inches (4"-6") (10 cm-1 5cm) for fusion welding.
In general, seams should be oriented parallel to the line of maximum slope; i.e., oriented along and
not across, the slope. For corners and odd -shaped geometric locations, the number of seams
should be minimized.
A seam numbering system compatible with a panel numbering system will be agreed upon at the
Pre -Construction Meeting.

1.3.A.2 Seaming Equipment and Products
The approved processes for field seaming are extrusion welding and fusion (hot wedge) welding.
Proposed alternate processes shall be documented and submitted to the Owner or his
representative for approval.
The extrusion welding apparatus small be equipped with gauges giving the temperature of the
apparatus.
The fusion -welding apparatus must be an automated device that produces a double seam with an
enclosed space or solid seam on thin mil material as specified.
The fusion welding apparatus shall be equipped with gauges giving the applicable temperature and
speed settings.
Agru America, Inc. shall verify that:
0 Equipment used for seaming is not likely to damage geomembrane;
0 The extrusion welder is purged prior to beginning a seam until all heat -degraded extrudate has
been removed from the barrel;
0 The electric generator, if utilized, is placed on a smooth base such that no damage occurs to
the geomembrane;
0 Buffing the geomembrane to remove waxes and oxides will be completed no more than one
(1) hour prior to extrusion welding (buffing is not necessary for hot wedge welding).
1.3.A.3 Seam Preparation
Agru America, Inc. shall verify that:
0 Prior to seaming, the area is clean and free of moisture, dust, dirt, and foreign material of any
kind;
0 Seams are aligned with the fewest possible number of wrinkles and "fishmouths".
1.3.A.4 Weather Conditions for Seaming
The high temperature limit for welding is based on two factors:
(1) The well being of the crew. Black lining material will get very hot when exposed to
sunlight. It is possible that the elevated sheet temperature in conjunction with immoderate ambient
conditions could place the well being of the crew at risk.

(2) Material Capability. The highest temperature at which the materials can be properly
welded is dependent upon such things as ambient temperature, wind, subgrade conditions,
exposure to sunlight, material type, and material thickness to name a few.
Thinner materials and low -density products are the most difficult to seam at high liner
temperatures. The problem typically is characterized by frequent burnouts (places in the weld
where the rollers lose traction and the machine stops moving causing the wedge to burn through
the tamer). The number of burnouts can often be reduced by increasing the speed and/or decreasing
the wedge temperature until a quality weld with a minimum number of burnouts is attained. The
sheet temperature may reach a point at which the supervisor determines there are an excessive
munber of burnouts at which time the supervisor will order welding to stop.
In some areas of extreme temperature conditions, the supervisor may determine it would be more
advantageous to work at night under artificial light, or split the workday to utilize the cooler
morning and late evening hours.
The lowest allowable temperature at which welding may be permitted is also dependent upon
conditions such as ambient temperature, wind, subgrade conditions, exposure to sunlight, material
type, and material thickness. Typically cold weather welding may proceed by reducing welding
speeds and/or increasing wedge temperature. Pre -heating the sheet in advance of the welding
apparatus may also be done by using a hot air blower.
Whenever temperatures become cold, increased attention should be given to pre -weld destructive
samples (Section 1.3.A.5). In cold conditions it is even more critical that these trial welds be
performed under the same conditions that will be seen during actual seaming.
The lowest temperature at which welding may take place is the lowest temperature at which
consistent passing trial seams can be performed under actual seaming conditions. In order to
obtain passing results, it may be necessary to preheat the sheet in advance of the welder and/or
shield the welding apparatus and the seaming area from wind_
In aD cases, the geomembrane will be dry and protected from the wind_
Agru America, Inc. will verify that these adjustments for various weather conditions are fulfilled
and will advise the Project Manager if they are not. The Project Manager will then decide if the
installation will be stopped or postponed.
1.3.A.5 Trial Seams
Trial seams shall be made on fragment pieces of geomembrane liner to verify that the seaming
equipment and conditions are adequate. Such trial seams will be made at the beginning of each
seaming period (startof day, midday, and anytime equipment is turned off and allowed to cool
down) for each seaming apparatus used. Trial seams shall be made under the same conditions as
actual seams.

The trial seam sample shall be approximately three feet (371.0m) long by one foot (1'/0.3m) wide
for extrusion and six feet (6'/2.0m) long by one foot (1'/0.3m) wide for fusion welds with the
seam centered lengthwise. Seam overlap shall be nominally three inches (3 "/7.5cm) for extrusion
welds and four to six inches (4"-6"/loom-15cm) for fusion welds.
Two adjoining specimens each one inch (I "/2.5cm) wide, will be cut from the trial seam sample by
the installer. The specimens will be tested respectively in shear and peel using a field tensiometer,
and they should not fail in the seam If a specimen fails, the entire operation will be repeated. If
the additional specimen fails, the seaming apparatus and procedures will not be accepted and will
not be used for seaming until the deficiencies are corrected and two consecutive successful full
trial welds are achieved.
1.3.A.6 General Seaming Procedure
Unless otherwise specified, the general seaming procedure used by Agru America, Inc. shall be as
follows:
0 The rolls of membrane will be overlapped by approximately four to six inches (4"-6"/10cm-
15cm) for fusion welding and three inches (3"/7.5cm) for extrusion welding. Seaming strength
is not a function of the overlap. The overlap simply needs to be wide enough to weld and test
properly.
0 "Fishrnouths" or wrinkles at the seam overlaps will be cut along the ridge of the wrinkle in
order to achieve a flat overlap. The cut "fishmouths" or wrinkles will be seamed and any
portion where the overlap is inadequate will be repaired in accordance with the repair
procedures described in Section 1.4.A.2.
0 Seaming will extend up the panels and well into the anchor trench.
0 For fusion welding on damp or muddy subgrade, a movable protective layer of plastic may be
required to be placed directly blow the overlapped membranes being seamed. This is to
prevent any moisture buildup between the sheets to be welded and/or to provide a more stable
base on which the fusion welding device can travel.
1.3.A.7 Non-destructive Seam Continuity Testing
1.3.A.7.1 Concept
Agru America, Inc_ writ non --destructive test all field seams over their full length using a vacuum
test unit, air pressure testing, or other approved method where applicable. The purpose of non-
destructive tests are to check the seams for leaks. It does not provide information on seam
strength or quality of bonding. Non-destructive testing will be carried out as the seaming
progresses, not at the completion of a job.

1.3.A.7.2 Vacuum Testing
The equipment will be comprised of the following:
0 A vacuum box assembly consisting of a rigid housing, a transparent viewing window, a soft
neoprene gasket attached to the bottom, port hole or valve assembly, and a gauge to indicate
chamber vacuum;
0 A rubber pressumJvacuum hose with fittings and connectors;
0 A bucket and wide brush, mop or spray assembly;
0 A soapy solution;
The following procedures shall be followed:
0 Energize the vacuum pump;
0 Wet a strip of geomembrane approximately twelve by 48 inches (12 x 4$"/0.3m x 1.2m) with
the soapy solution;
0 Place the box over the wetted area;
0 Close the bleed valve and open the vacuum valve;
0 Ensure that a leak tight seal is created;
0 For a period of approximately five to ten (5-10) seconds, examine the geomembrane through
the viewing window for the propagation of soap bubbles;
0 After five to ten (5-10) seconds, close the vacuum valve and open the bleed valve, move the
box over the adjoining area with a minimum three inches (3"n.5cm) overlap, and repeat the
process;
0 All areas where soap bubbles appear will be marked and repaired in accordance with Section
1.4.A, and;
0 Vacuum tested seams are recorded on Daily Progress Reports.
1.3.A.7.3 Air Pressure Testing (For Double Fusion Seam Only)
The equipment shall be comprised of the following:
0 An air pump (manual or motor driven) equipped with pressure gauge capable of generating
and sustaining a pressure between 25 and 30 psi (160 and 200 kPa);

0 A rubber hose with fittings and connections; and
0 A hollow needle and clamp assembly shown in Figure 2.2, Section 2.1.F or other approved
pressure feed device.
The following procedures will be followed-
0 Seal both ends of the seam to be tested;
0 Insert needle or other approved pressure feed device into the tunnel created by the fusion
weld;
0 Energize the air pump to a pressure between. 20 and 30 psi (160 and 200 kPa), close valve,
and hold pressure for approximately five minutes;
0 If loss of pressure exceeds the values listed below, or does not stabilize, locate faulty area and
repair in accordance with Section 1.4.A;
0 Release air pressure by puncturing seam to assure there is no blockage in the as channel and
verify that the full seam has been pressurized,
0 Remove needle or other approved pressure feed device and seal, and;
0 Pressure tested seams are recorded on Daily Progress Reports.

1.3.A.8 Destructive Testing
1.3.A.8.1 Introduction
Destructive testing of seams is important because it provides direct evaluation of seam strength
and bonding efficiency which indicates seam durability.
Destructive testing involves two techniques:
I . Shear Testing — Applies a tensile stress from the top sheet through the weld and into the
bottom sheet and;
2. Peel Testing — Peels the top sheet back against the overlapped edge of the bottom sheet in
order to observe how separation occurs. The peel test indicates whether or not the sheets are
continuously and homogeneously connected through the seam.
1.3.A.8.2 Location and Frequency
Destructive seam tests will be performed at random selected locations. The owner and/or owners'
representative will select locations where destructive samples will be cut.
A frequency will be agreed upon by Agru America., Inc_ and the Project Manager at the Pre -
Construction Meeting. Unless otherwise specified, destructive samples should be pulled at
intervals of one (1) sample for every 500 linear feet of weld.
The seaming technician will not be informed in advance of the locations where the seam samples
will be taken,
1.3.A.8.3 Sampling Procedure
Samples will be cut by Agru America, Inc. as the seaming progresses. When cutting samples
above an existing geomemzbrane, hook blade knives should be used.
A number will be assigned to each sample which is to be based upon seam and sample number and
mark it accordingly.
Destructive sample locations will be recorded on a daily report and on the as -build drawing; and
All holes in the geomembrane resulting from destructive seam sampling will be immediately
repaired in accordance with repair procedures described in Section 1 A.A.
1.3.A.8.4 Size of Samples
At a given sampling location, two (2) coupons for field testing should be taken. Each of the
coupons will be one inch (1 "/2.5 cm) wide by twelve inches (12"/0.3m) long with the seam
centered parallel to the length The distance between these two (2) coupons will be twelve inches
(I 2"/0.3m).

If both coupons pass the field test described in Section 1.3.A.9.5, a sample will be cut between the
two (2) coupons. The sample will be cut into three (3) parts and distributed as follows:
0 Two (2) one inch (1 "12.5 cm) wide strips will be tested in the field for peel and shear and will
not fail in the seam. If seam strengths are being evaluated, samples should be cut with a die to
provide proper geometry.
0 If any field test samples fails to pass, then the procedures outlined in Section 1.3.A.9.6 will be
followed.
0 If the initial sample coupon test passes with Film Tear Bond (FTB) (see Figures 2.5 and 2.5 in
Section 2.0), the sample is considered passing unless by specification, requires further testing
to obtain quantitative results per Table 3. If it fails, the seam should be repaired in accordance
with Section l A.A.
1.3.A.8.5
Electric or hand tensiometer destructive testing is to be carried out in the field. Testing procedure
is as follows:
0 Two (2) one inch (1 "12.5 cm) wide strips will be tested in the field for peel and shear and will
not fail in the seam. If seam strengths are being evaluated, samples should be cut with a die to
provide proper geometry.
0 If any field test samples fail to pass, then the procedures outlined in Section 1.3_A.9.6 will be
Mowed.
0 If the initial sample coupon test passes with Film Tear Bond (FTB) (See Figures 2.5 and 2.6 in
Section 2.0), the sample is considered passing unless by specification, requires further testing
to obtain quantitative results per Table 3. If it fails, the seam should be repaired in accordance
with Section 1 A.A.

1.3.A.8.6 Procedures for Destructive Test Failure
The following procedures will apply whenever a sample fails a destructive test. Agru America,
Inc. has two options:
1. Reconstruct the seam between any two passed test locations.
2. Trace the welding path to an intermediate location ten feet (I 073m) minimum from the
point of the failed test in each direction and take a small sample coupon for an additional field test
at each location_ If these additional samples pass the field test, then full samples are taken. If these
samples pass the tests, then the seam is reconstructed between these locations. If either sample
fails, then the process is repeated to establish the zone in which the seam should be reconstructed.
All acceptable seams must be bounded by two (2) locations from which samples passing
destructive tests have been taken or entire seam is capped.
Agru America, Inc. will document all actions taken in conjunction with destructive test failures,
e.g., capping of failed seam area_
1.3.B Geotextiles, Geonets, and Geocomposite Joining
1.3.B.1 Geotextiles
Geotextiles may be installed by overlapping, by thermally bonding on a spot or continuous basis,
or by sewing as specifications dictate.
If sewing is required, the thread used will be a polymeric material with chemical resistance similar
to the geotextile.

1.3.13.2 Geonets
Geonets may be butt joined or lapped if specified. Nylon/phoic cable ties will be applied to the
net edge at five foot (571.5m) intervals along the edge.
End splices will be made as follows:
1. On slopes, the ends will overlap two feet (270.6m) with uphill panels on top and two (2)
rows of cable ties applied.
2. In flat areas, the ends will overlap a minimum to two inches (2 "/5 cm) and one (1) row of
three (3) cable ties applied.
1.3.13.3 Geocomposites
Geocomposites can be overlapped with the net portion tied and the geotextile portion thermally
bonded or seamed as required by the project specifications.
1.3.C. Geosynthetic Clay Liner (GCL) Joining
Seaming of GCUs is achieved by simply overlapping the GCL panels. Care must be taken in order
to detennine if any loose bentonite should be spread between the overlap.
Alternately, the geomembrane backing can be welded in accordance with the membrane and GCL
manufacturer specifications.
1.4 Geosynthetic Repair Procedures
1.4.A Defects and Repairs of Geomembrane
1.4.A.1 Identification
All seams and non -seam areas of the geomembrane will be examined by Agru America, Inc. for
identification of defects, holes, blisters, undispersed raw materials and any sign of contamination
by foreign matter.
Defective/damaged materials will be identified via a deficiency report, either separately or on the
Daily Report. Actions taken to resolve or correct the problem will also be recorded on the similar
form.
Defects, holes, blisters, undispersed raw materials, signs of contamination by foreign matter,
unacceptable welds in geomembranes and other unsatisfactory conditions will be identified. The
repair/corrective action to repair the problem will also be recorded.

1.4.A.2 Repair Procedures
Any portion of the geomembrane failing a destructive test will be repaired. Several procedures
exist for the repair of these areas_ The final decision as to the appropriate repair procedure will be
agreed upon between the Project Manager and Agru America, Inc.
The procedures available include:
0 Patching — Used to repair holes, tears, and contamination by foreign matter,
0 Buffing and re -welding — Used to repair small sections of extruded seams;
0 Spot welding or seaming — Used to repair pinholes, or other moor localized flaws,
0 Capping — Used to repair large lengths of failed seams; and
0 Topping -- Used to repair areas of inadequate seams which have an exposed edge.
In addition, the following provisions will be satisfied:
Surfaces of the geomembrane which are to be repaired will be abraded no more than one (1) hour
prior to the repair;
All surfaces must be clean and dry at the time of the repair;
All seaming equipment used in repairing procedures must be approved;
Patches or caps shall extend beyond the edge of the defect, and all corners of patches will be
rounded with a radius.
1.4.A.3 Repair - Non-destructive Testing
Each repair will be non-destructively tested using the methods described in Section 1.3.A.7.2 as
appropriate. Repairs which pass the non-destructive test will be taken as an indication of an
adequate repair. Failed tests indicate that the repair will be redone and re -tested until a passing
test result is obtained.
1.4.B Geotextile, Geonets, and Geocomposite Repairs
Any holes, tears, or burn throughs from thermal seaming in geotextiles will be repaired by
patching with the same geotextiles_ The patch will be a minimum of twelve inches (12"/30cm)
larger in all directions than the area to be repaired and will be spot bonded thermally.
Any holes or tears in geonets will be repaired by patching with the same geonet. The patch will be
a minimum of twelve inches (12"/30cm) larger in all directions than the area to be repaired. The
patch will be tied in place using a minimum of four (4) nylon cable ties.

1.4.0 Geosynthetic Clay Liner (GCL) Repair Procedures)
GCLs will be inspected for cuts, tears, or areas of bentonite loss.
The area to be repaired (patched) must be free of contamination by foreign matter. Patches must
have a twelve inch (12"/30cm) overlap around the damaged area For fabric -encased GCLs the
patch is to be tucked into place with excess bentonite poured over the overlap.
1.5 Backrilling of Anchor Trench
The anchor trench, if any, will be adequately drained by Owmr/Earthwork Contractor to prevent
ponding or otherwise softening of the adjacent soils while the trench is open. The anchor trench
will be backfilled by the Earthwork Contractor or as outlined in the specifications and bid
documents.
Since backfilling the anchor trench can affect material bridging at toe of slope, consideration
should be given to backfill the liner at its most contracted state; preferably during the cool of the
morning or extended period of overcast skies. Care shall be taken when bacldilling the trenches to
prevent any damage to the geosynthetics.
1.6 Lining System Acceptance
The geosynthetic lining system will be accepted when:
0 The installation of materials are deployed and welded; and
0 Verification of the adequacy of all seams and repairs including associated testing is complete.
1.7 Soils in Contact with the Geomembrane
Important points for quality assurance of sons in contact with geomembranes include:
0 A geotextile or other cushion approved by the designer may be installed between angular
aggregate and the geomernbrane;
0 Equipment used for placing sod will not be driven directly on the geomembrane;
0 A minimum thickness of one foot W/0.3m) of soil is recommended between a light dozer
(such as a CAT D-3 or wide track caterpillar D-6 or lighter) and the geomembrane; and
0 In areas of heavy traffic such as access ramps, soil thickness should be at least two to three
fret (2-3'/0.6-0.9m).

Soil/Earth Cover on Top of Geomembrane
Placement of soil (sand or other types of earth) cover on top of the liner will not be performed
until an destructive and non-destructive testing has been performed and accepted_
Placement should be performed to minimize wrinkles. Equipment operators should be briefed on
method and timing of soil placement to deal with the affects of thermal expansion and contraction
of the liner. Soil placement during cooler part of the day minimizes wrinkle problems.
Material placed on top of the liner should be back -dumped on liner and, in order to avoid the
formation of wrinkles, efforts should be made to load the soil so that it comes down on top of the
liner rather than being pushed across the sheet. This is done by:
1. Using a front-end loader to place soil ahead of spreading soil cover; and
2. Spreading soil by building a mound at the edge of soil, then pushing soil up and over the
mound causing it to core down on the liner.
If a wrinkle forms, every effort should be made to walk the wrinkle out.
Minor folding over of wrinkles is acceptable providing an even transition occurs at the tail of the
wrinkle. If excessive stress points are created at the tail of the wrinkle, the wrinkle should be cut
out and repaired per Section 1 A.A.
2.0 WELDING SYSTEM DETAILS
2.1 Details of Fusion Welding System
2A.A. introduction
The fusion welding system is the primary seaming system for geomembrane installation and the
extrusion welding system is utilized for repairs and detail work_
The fusion welding apparatus is self-propelled and produces a double seam with an enclosed air
channel for testing. A single wedge may be made available for very thin materials on special
request (certain lead times in obtaining this equipment may apply) -
The wedge itself contains two cartridge style heaters and its temperature is controlled by a closed
loop feedback controller using a thermocouple positioned in the wedge. This maintains the wedge
temperature typically to within f ten degrees Centigrade (1 U° Q of the setpoint temperature
during welding.

In addition to these electronic devices, a great deal of care has been taken to assure that the
mechanical design is as self-adjusting and trouble free as possible. The wedge for example is free
floating and pivots about the same axis as the drive rollers. This means that no wedge position
adjusts must be made for welding materials of different thickness. Also, the drive system
consists of totally enclosed gears, chains, and shafts which need no adjustments and are protected
from the environment.
2,1.B Geomembrane Preparation
0 Correct performance of the welder requ res that the geomembrane be brought to its exact plan
position for final installation and seaming.
0 The two (2) geomembrane panels to be joined must be properly positioned such that
approximately four to six inches (4-6"/10-15 cm) of overlap exists.
0 If the overlap is insufficient, lift up the panel to allow air beneath it and "float" it into proper
position. Avoid dragging sheets, particularly when they are on rough soil subgrades.
0 There should be no excessive undulations (waves) along the seams during the seaming
operation. When excessive undulations are present they often lead to the undesirable
formation of"fishmouths" which must be trimmed, laid flat, and reseamed via a patch.
0 There will generally be slack in the geomembrane depending on the ambient temperature,
length of exposure time, etc.
0 The sheets which are overlapped for seaming must be clean-
0 The sheets which are overlapped for seaming must be free of moisture in the area of the seam
0 Seaming is not allowed during rain or snow, unless the seam is covered with an enclosure.
0 The soil beneath the geomembranes should not be frozen. The heat of seaming can thaw the
frost allowing water to be drawn into the region to be joined. Seaming over frozen soil,
however, can be accomplished with rub sheets of geomembrane directly under seam edges.
0 Ambient temperatures for seaming should be above freezing i.e. thirty-two degrees Fahrenheit
(321 F/O*C). However heat seaming below thirty-two degrees Fahrenheit (32aF/0'C) can
proceed with caution as stated in the next item and in Section 1.3.A.4.
0 For cold weather seaming, it may be advisable to preheat the sheets with a hot air blower, to
Use a shield of some sort to prevent heat losses during seaming, and to prepare more test
welds in order to determine appropriate seaming conditions (e.g. equipment temperatures
should be set higher and seaming rates slowed down during cold weather seaming). For
further guidance see Section 1.3.A.4.

2.1.0 Equipment Preparation
0 A working and properly functioning power source must be available within close proximity of
the seaming region. if a generator is utilized, rubber tires must be used, or a smooth plate
placed under the generator such that it is completely stable so that no damage can occur to the
geomembrane. Fuel (gasoline or diesel) for the generator should be stored off the
geomembrane.
0 As the fusion method is one of melting the opposing surfaces of the two (2) geomembrane
panels to be joined, no grinding of the geomembrane sheets is necessary, nor allowed.
0 Tacking of the geomembrane panels, as done in extrudate fillet seaming, is not needed.
0 The wedge itself should be inspected to see that it is uniform and reasonable tapered. Various
types are currently available. Some are smooth surfaced while others have patterned ridges in
the direction of the seam The taper dimensions vary according to different types of machines.
The major point for inspection is that no sharp edges should exist where geomembrane sheet
surfaces must pass.
0 Nip rollers for applying pressure on the sheets and driving the device (most often knurled
rollers) follow the wedge. They should be inspected for sharp surfaces or excessive wear.
0 For a dual, or split seam, the recessed space for the air track should be examined-
0 As the geomembrane panels pass through the machine, they must properly come in contact
with the wedge. Fusion welding machines are equipped with pressure shoes or rollers which
assure contact between the sheet and the wedge as the material passes through the machim-
Once the welding machine has been set up for a particular thickness, further field adjustn-&nts
are not required.
0 The front part of the seaming device should be inspected for sharp corners and irregular
details which may damage the geomembrane-
0 Temperature controllers on the fusion device should be checked periodically-
2.1.D Seaming Process
The fission system is properly positioned for the snaking of a dual (split) seam.
The principle of fusion welding is that both surfaces to be fused come into intimate contact with
the hot wedge, or anvil. The wedge lifts up both overlapped panels off the subgrade and fusion is
brought about by compressing the two molten surfaces of the sheet together, causing an
intermingling of the polymers-

Figure 2.1
0 Temperature, speed, and nip force will vary according to the geomembrane thickness being
installed.
0 Ambient factors such as clouds, moisture, and hot sun may require the temperature and/or
speed setting of the wedge to vary. A test strip should be run before welding begins, which
will enable the operator to find the proper settings for the particular conditions that day. See
Section I.3.A.5.
0 After placing the machine into the overlapped sheet of material, pick it up a few inches,
loading the bottom sheet fast, and then the top sheet between the wedge and respective
pressure shodrolier. When top and bottom sheets are loaded, engaging the nip rollers will
secure the position of sheet and wedge and start the welding.
0 It is necessary that the operator keep constant visual contact with the temperature controls,
and the completed seam coming out of the machine. Occasional adjustments of speed may be
necessary to maintain a consistent weld.
0 Occasionally on some soils, the wedge tends to "bulldoze" into the ground as it travels. This
causes soil to enter the weld making the seam weak and unacceptable. To overcome this, it is
recommended that the operator take some of the weight off the front of the machine by lifting
it slightly. Alternatively, some type of base for the machine to travel on could be provided -
Strips of geotextile or geomembrane ("rub sheets") have proven effective to prevent this
bulldozing effect.
2.1.E After Seaming
0 A smooth insulating plate or heat insulating fabric is to be placed beneath the fusion welding
apparatus after use.

0 A slight amount of "squeeze -out" or "flashing" in the weld is a good indicator that the proper
temperatures were achieved. Some melted polymer laterally extruded out of the seam zone
indicates a proper searn.
0 Nip/drive roller marks will always show on the surface and will be just barely evident to the
touch.
0 The fusion device requires only a few adjustments, but it is very important that they be
checked daily. Cleaning of machine should be done frequently, and at least daily.
2.I.F Dual Track Fusion Air Pressure Testing
General
The automatic fusion searning machine creates two distinct seams. These two seams are separated
by a void or air space. This seam design is intentional for two reasons. First, it allows a very
positive test for leak integrity, and second, the double weld seam offers both a primary and a
secondary seal for the seam.
Air Pressure Test Procedure: (More Information in Section 1.3.A.7.3)
1. Seal one end of the seam by applying heat to the end of the seam, via hot air gun, until
"flow temperature" is achieved
2. Clamp off end using hand vise gripper or tape used for this purpose_
3. A pressure gauge/needle assembly is inserted into void or air channel.
4. Air pressure is then applied into the air channel with the use of an air pump per the
following schedule:

5. Pressure test seams according to the initial pressure test schedule. Hold test for five
minutes. If no pressure drop is greater than the maximum allowable pressure drop the seam is
judged leak free.

100 mil

Note: At all times before heat sealing the end of the seam, the operator should insure that the void
or air channel is free of obstruction_
6. On completion of the test, the air channel should be cut open. The pressure gauge reading
should immediately drop to zero indicating that the air channel was continuous and unblocked.
FIELD SEAM FAILURE
Should failure occur through excessive leak down over the scheduled time period, check both
ends of seam to insure proper seal and re -test. Should failure reoccur, check the top fusion seam
by applying a constant flow of air pressure to void air channel. Mix a strong solution of liquid
detergent and water and apply an ample amount to the top fusion weld._ Any failure or leak will be
bxficated by continuous bubbles appearing.
If no failure appears in the top fusion seam area, check systematically by isolating random sections
of the seam. This should be accomplished in 150 linear foot 45m) long sections of seam. Then re-
test each section by pressure testing until the leak is located. Repair failed seam area by extrusion
welding the outside edge of the top fusion weld between areas of failure. Then vacuum test
repaired seam. All repairs in accordance with Section 1.4. A.
2.1.G. Peel Test for Fusion Seam Weld
For more information see Section 1.3.A_9
Procedure:
1. Cut specimen approximately one inch wide by approximately six inches long (1 x 6"12.5 x
15cm).
2. Only one track is peeled apart in this destructive test. The other track is for the purpose of
air pressure testing capabilities.
3. Clamp bottom tabs into the testing machine (Field or Lab Tensiometer). Turn on machine
and pull the seam (See Figure 2.3).

4. All testing of destructive samples of fusion seam will be in accordance with ASTM D443 7
which references ASTM 413 for peel.
Passing results for a seam are deternrined to be FI`B per the chart titled, Destructive Testing of
Dual Hot Wedge (See Figure 2.5).
Figure 2.3
2.2 Details of Extrusion Welding System
2.2.A Introduction
The Fusion Welding System is the primary seaming system for geomembrane installation. The
Extrusion Welding System is utilized for repairs and detail work. The Extrusion Welding System
produces a seam quality equal to the Fusion Weld and has the advantage that all welds are applied
on top of the geomembrane which allows its use at "T" intersections and in irregular seam areas
such as pipe boots.
The extrusion welder will have two independent heating zones, each with its own closed loop
temperature control system. These two zones are typically referred to as the nozzle and the
extruder. The nozzle thermocouple is positioned approximately one inch (1 "/2.5cm) from the end
of the steel nozzle which rides on the sheet giving good control over the temperature of the
molten polymer as it contacts the sheet. Some extrusion machines may only have one heating zone
which is referred to as a shoe. This machine needs only one heater since there are no rotating tips.
The extruder and nozzle will be insulated to prevent excessive heat loss in cold and/or windy
conditions as well as to provide a safe working environment for the operator.
When tested in peel the numerical values for weld strength of an extrusion weld will be slightly
lower than for fusion welds. The lower value is the result of the weld bead on top of the liner
changing the geometry of the load application in the tensile test and not an indication of inferior
weld quality.

2.2.B Geomembrane Preparation
Geomembrane preparation is the same as described for the fusion weld, Section 2.1.B.
2.2.0 Equipment Preparation
A working and properly functioning power source must be available within close proximity of the
seaming region. if generator is utilized rubber tires must be used, or a smooth plate placed under
the generator such that it is completely stable so that no damage can occur to the geomembrane.
Fuel (gasoline or diesel) for the generator should be stored off the geomembrane.
The extrusion welder is a completely self contained system which requires no adjustments after it
has been initially set up for a particular geomembrane thickness.
An initial inspection of the extrusion welder should be made before it is heated to confirm that the
electrical cords, msalation and covers are in good condition and that the welding nozzle is correct
for the geomembrane to be seamed.
The welding machine should be connected to a proper power supply and heated to the correct
welding temperature for the geomembrane to be seamed.
After the unit has reached correct operating temperature, clean, dry welding rod should be
inserted and the unit operated for several minutes to confirm that the temperature controllers are
operating properly and that the welding rod feed system is operating properly.
The Teflon shoe(s) should be checked for excessive wear and replaced if necessary and they must
be trimmed for proper control of the weld bead configuration
2.2.D Seaming Process
Geomembrane to be extrusion welded must have low molecular weight polymer (waxes) and
surface oxidation removed by lightly grinding the weld surface. The grinding is performed parallel
to the seam and controlled such that grinding marks do not extend more than 0.25 inches (6rrm)
outside the area of the weld bead.. Grinding should precede the actual welding as closely as
possible but in no case should grinding precede welding by more than one hour. 80 mil (1.5mm)
or thicker geomembranes should have the edge of the top sheet beveled by grinding to
approximately a 45' angle.
The geomembrane to be extrusion welded must be temporarily bonded to hold the material in
place until the extrusion weld bead cools and attains fiifi strength. Automatic or hand-held hot air
tack welds are therefore applied prior to extrusion welding.
The extrusion welder barrel should be purged of all degraded polymer prior to the start of
seaming.

The welding operation should be observed to assure that the weld bead is centered over the edge
of the top overlapped sheet and that weld bead appearance is smooth and uniform.
All extrusion welds should be non-destructively tested by vacuum testing as described in Section
i.3.A.7.2.
Destructive tests, per 1.3.A.9 and Figures 2.4 and 2.6 are conducted when seam lengths are
adequate.

AGRU AMERICA, INC. - OA/OC
Manufacturing — Quality Assurange Quafity Control
AGRU AMERICA, Inc. extrudes high density polyethylene (HDPE) and linear low density
polyethylene (LLDPE) geomembrane at its plant located at 500 Garrison Road, Georgetown, South
Carolina, 29440. This geomembrane is available as per attached packaging standard (Attachment "A").
Our USA Manufacturing Quality Assurance Program is dependent on the utilization of an in-house
Laboratory which is, when necessary, complennented with testing performed by certified outside
laboratories such as.
• Precision Geosynthetic Laboratories; Anaheim, CA
Telephone [phone]; Fax [phone]
• TRllEnvironmental, Inc.; Austin, Texas
Telephone [phone]; Fax [phone]
And other GRI-LAP accredited laboratories_
Raw Material - Data Sheet
HDPE and LLDPE resin is supplied to our plant in bulk and subjected to the following procedures:
• Prior to shipment, our resin supplier submits a certificate of analysis (Attachment `B").
Once approved, the resin is released for shipment to our plant.
• One sample is taken from each rail car after arrival and tested as follows:
Melt Index ASTM D-1238 Condition E.
• Once the tests have been completed and results found to be in compliance with our
requirements, the resin is then unloaded into our silo system.
• At this stage, our supplier has performed one battery of tests and Agru America has
performed one to verify the manufacturer's certificate of analysis.
* Off specification resin is returned to the supplier.
• The Manufacturer's MFI Test Data is reported on the Quality Certificate (Agra America's
MFI Testing is done to verify this data).
The Extrrision Process
The resin is conveyed through a vacuum pump system and flexible hoses to a dryer hopper, feeding the
resin by gravity into an 8-inch barrel. This barrel is divided into five heating zones, each heating zone
being computer controlled and constantly monitored

A screw in the barrel turns at a prescribed and monitored speed. It conveys the resin slowly to fill]
plastication, and then the plasticated resin is fed through a manifold into a coat hanger die having a
width of approximately 24 feet. The die lips are open to a prescribed distance governed by the thickness
of the geomernbrane to be extruded.
Exiting the die, the plasticated resin forms a controlled and monitored bead, which feeds into a chrome
three -roll stack in a prescribed pattern Each chrome roll is set at a prescribed temperature, controlled
by water circul-Wmn_
Exiting the controlled cooling of the roll stack, the geomembrane travels down the take off haulers
towards the winder. On the way to the take off, the liner is trimmed to bring the finished width to the
applicable stardard. Trnmmirgs are granulated..
The trimmed edge of one side of the geomembrane is marked at every 3.28 R with thickness, Agru
America name and year of manufacture. This marking also serves as product identification.
The geomembrane is visually inspected for surface defects as it travels down the take off by both the
extruder and the winder operators.
The geomembrane is wound on a recycled HDPE core having 6" ID (I50mm), 7" OD (175mm) and
22'8" (6.8m) length. Each smooth roll weighs approximately 3,000 pounds (1360 kg). Microspikeo
rolls weigh approximately 3,200 pounds (1450 kg). All rolls are fitted with two nylon slings when
shipped•
Post Extrusion!Quality Control
Once start-up conditions are over and commercial extrusion is initiated, post -production quality control
cones into operation. A series of test procedures are performed at an approximate frequency based
upon the weight of the resin extruded at intervals of each roll:; 20,000; 40,000 and 190,000 pounds_
Actual Standard test frequencies are: 20,000 pounds = every five rolls; 40,000 pounds = every ten rolls;
180,000 pounds = Lot (railcar). These frequencies are based on an approximate roll weight of 3,000
pounds and are subject to change based on Customer Project Specifications.
A sample approximately I I" by the full width of the geomembrane is taken from every roll. Based on
the above weight frequencies, certain specimens are die cut, tested and the results summarized on the
Quality Certificate (Attachments C-G) issued by our Quality Control Departmenrt. The certificate is
signed electronically by the Quality Control Manager. The Quality Control Manager reports directly to
the President of the Company.

Rolls failing to comply with either Customer Project Specifications and/or our own latest revision to our
published data sheets are set aside and re-classified as outside standard.
Certificates of Conformity are provided for the following products:
Smooth Liner - Attachment "C"

Point of Contact: Anthony Smith [phone]
Comments:
1. The previous permit had the following artal9tirW monitoring parameters: BOD,
COD, TSS, TKN, Nitrate/Nitrite Nitrogen, TP, Hexamine, Formaldehyde, Total
Lead, and pH. All analytical monitoring for -these parameters were above their
respective cutoff concentrations of 30 mg/1,120 mgll, 100 mg/l, 20 mg/l, 10 mg/l, 2
mgfl, no cutoff for hexamine, 0.18 mg/l, 0.033 mg/l, and 6-9 s.0 over the permit term.
2. The analytical monitoring data shows no improvement over the life of the permit.
Continued quarterly monitoring with cutoff concentrations is recommended_ This
will allow the Division to have a good picture of the pollutants leaving the site and
the cutoff concentrations will provide incentive to take additional steps to reduce the
pollutant concentrations leaving the site. Ammonia was a parameter that was added
due to its toxicity and the nature of the industrial activity at the subject facility.
3. The visual monitoring requirements were adequately satisfied in the permit.
4. A site visit was completed for this facility. It appears that Wright Corporations has
taken steps to segregate stormwater that comes into contact with process areas from
other stormwater. This effort should be continued. There was also mention of
treating this wastewater in an future offsite sewage treatment plant_ From looking at
the ground water monitoring of the site, it appeared that the ground water has the
same level of pollutants as indicated in the stormwater runoff. With all the springs
that discharge ground water all over the site, it may be difficult to improve the quality
of. the stormwater very much.

Dear Mr. Lowry:
Division personnel have reviewed and approved your application for renewal of the subject
permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued
pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between North Carolina and the U.S. Environmental Protection Agency dated May 9, 1994
(or as subsequently amended).
This final permit includes the following changes from your current permit:
➢ The processed wastewater discharge (outfall 001) has been eliminated. This discharge
is connected to Columbus County Publicly Owned Treatment Work (POTW).
3'- A formaldehyde limit of 7.48 mg/L has been added to outfall 002 because the parameter
presented a reasonable potential to exceed the NC water quality standard based on a
statistical analysis of the effluent data.
A total residual chlorine (TRC) limit has also been added to outfall 002. The limit
will be effective on--M—a—rc-'F 1, 2009. Monthly monitoring is required beginning on
September 1, 2007. See the attached TRC policy memo for details.
➢ Monthly monitoring for various toxicants, and quarterl . whole effluent toxicity
testing requirements have been added to this permit ecause the Division has adopted
a permitting strategy for all reverse osmosis (RO) and ion exchaners
across the State. These requirements reflect the minimum constituents and monitoring
frequencies for these types of discharges.
The Division understands that Hexion Specialty Chemicals is currently investigating
the potential to connect the reverse osmosis reject and water softener backwash
sources to the Columbus County POTW. Hexion should be aware that this type of
wastewater may cause an aquatic toxicity problem in the effluent from Columbus
County POTW- The Division recommen s at pi o s les be performed for whole t��o` Caratina
effluent toxicity to simulate the addition of this type of wastewater into the Columbus ) atura!!ry

A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of4.7 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or
subsequent versions or "North Carolina Phase lI Chronic Whole Effluent Toxicity Test Procedure" (Revised -
February 1998) or subsequent versions. The tests will be performed during the months of February, May,
August and November. Effluent sampling for this testing shall be performed at the NPDES permitted final
effluent discharge below all treatment processes.
If the test procedure, performed as the first test of any single quarter, results in a failure or ChV below
the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two
following months, as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Prr% Pdl1rp" (R Pyi Qpd-P.4"1nni Z 009) :l;ee^::r,:t
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are specified
in the "North Carolina Phase 11 Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998)
or subsequent versions.All toxicity testing results required as part of this permit condition will be entered on
the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the
parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value_ Additionally, DWQ Form
AT-3 (original) is to be sent to the following address:
Attention: NC DENR / DWQ / Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no
later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is
employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form
indicating the facility name, permit number, pipe number, county, and the month/year of the report with the
notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental
Sciences Branch at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month. Should any test data from this monitoring
requirement or tests performed by the North Carolina Division of Water Quality indicate potential impacts to
the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements
or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later than
the last day of the month following the mouth of the initial monitoring.

Linda about Wright Corp. a while ago, so I'm guessing you're the one who's working
on this one.) Are there any outstanding issues for this site that we need to
address in the next permit?
If you've been swamped and just haven't had a chance to send it on, don't feel
badly; I'm still a ways off from drafting up Wright's permit! I just wanted to
make sure the report didn't get lost_
Thanks,
Bethany G.

I finally had to admit to myself that, with the additional responsibilities, I
needed to assign some projects to others. Linda Willis and Tom Moore will be
visiting SAS and Wright Corp and preparing recommendations for the renewal of the
permits. That should be done in the next few days. since there were some messy
areas at SAS in the past, I am uneasy giving a sign off without a visit. Please
let me know if that schedule will meet your needs.

Hi Ed,
I'm sure things are busy as ever down your way with the transition from Rick
Shriver! I just wanted to check on the status of a staff report request I'd
sent back in December, since I had it scheduled to go to notice next week_ The
facility is South Atlantic Services there in Wilmington, NCS000084. It's a
stormwater permit renewal that doesn't have any analytical monitoring
requirements. Do you know the status of that staff report, or could you let me
know who the reviewer is? Since there's no monitoring, I hate to hold it up
too much longer unless there are outstanding issues with the facility, or other
issues the region feels need addressing. Thanks so much!
Hi Bethany,
Thanks for the email. I have yet to write up the Wright Corp. NPDES Stormwater
inspection. I visited'with Danny Smith (Wetlands/Stormwater Enforcement) and he
suggested we take a very hard line with them on the matter. As a matter of
consistency, I would start by sending a NOTICE OF VIOLATION to them for the high
levels of contaminants in their stormwater runoff. They are not doing a very good
) of 2 5P-/2005 4:37 PM

Re: {Fwd: Re: S. Atlantic Services - NCS0000841
job of keeping these contaminants on site. They have to improve their BMP and I
would absolutely insist that *all* *their stormwater discharge points be tested*
rather than only 3 out of 7 of the discharge points. We cannot assume all discharge
points will be "represented" by any of the others, and if we are to assume that,
their situation is even that much more scarier because the contamination in the three
they monitor is extremely high for COD, BOD, NH3, Formaldehyde and Hexamine. I will
work on that report and have it done and forwarded to you by email no later than
Wed. I will recommend the following comments in my report regarding their permit
renewal:
In lieu of the high levels of *HOD, COD, NH3, TKN, No3+NO2, formaldehyde and
hexamine*. . . They must come up with some practical BMPs that work. Anthony Smith
indicated they were doing all they could to prevent contamination to stormwater
runoff. Some of their difficulties is the way they store dry chemicals in the
storage buildings_ Dry chemical is brought on site in large tote bags. Some bags
get damaged moving them to the storage buildings, raw material spill out and people
walk through it and drive fork lifts through it spreading on the property grounds
outside the buildings. He said they are doing all they can, but given the high
levels of contamination, they need to tighten up. You may want to state in their new
permit (if you can) that
1. They must show significant improvements in the concentrations of contaminants
(*BOD, COD, NH3, TKN, NO3+NO2, formaldehyde and hexamine)*, or they will be required
to contain the contaminated stormwater runoff and treat it in their wastewater
treatment facility as a wastewater. The levels that are apparently leaving via
stormwater are *absolutely unacceptable*.
2. They need to test every discharge point, not just 3 out of 7. unless they
have data to prove that the other 4 are truly representative of one of the other 3.
This office has seen no supporting documentation to that effect (yet).
3. Because of the levels of contamination they have leaving the site via stormwater
runoff, they need to be sure to maintain no less than the same frequencies of
sampling as they did last year in order for them (and Surface Water Protection
Section) to determine if progress in the right direction is being made by the
improvements they make to their BMPs..
Did you send me your staff review and evaluation form for Wright yet?? I saw a copy
of one for SAS that Tom got from you, but hadn't seen one for Wright yet. I'll scan
the files for it again, but don't recall seeing it. I'll keep you posted.

(Attach additional sheets of narrative and checklists as necessary)
1. Permit:
Your permit became effective February 4, 2000 and expired on February 28, 2005.
The permit is currently in the renewal process and is under review. The Wilmington Regional
Office conducted this inspection in conjunction with the permit renewal review.
The pennittee is reminded to read, understand and comply with all of the terms and conditions
contained in the permit. If you have questions concerning your responsibilities, call the
Wilmington Regional Office to speak to a Division of Water Quality staff member.
2. Facility Site Review:
The overall condition of the plant site was satisfactory. The appearance of the facility was in
acceptable condition indicating that the current housekeeping practices are fair.
Upon inspection of the monitoring results for stormwater discharge feomz@tqfalls&08?•t003dzznd

being ter rrnd handla% As specified in the current permit, this monitoring data is evaluated
against the "cutoff levels " presented in the permit. The concentrations of various pollutants
were significantly higher than the corresponding "cut-off level " which indicates that substantial
improvements in' housekeeping, material handling, and containment are needed.
The facility should review the Stormwater Pollution Prevention Plan and current standard
operating procedures in these areas to identify any areas that may be improved. The facility
should implement the appropriate changes in an effort to improve current practices and reduce
stormwater pollution. These analytical results do raise concern regarding the potential impacts
to surrounding surface waters. Therefore, it is recommended that the facility take immediate
steps to identify and improve facility operations and practices that contribute to the excessive
stormwater pollution discharges.
3. Adequacv of Stormwater Pollution Prevention Plan (SWPPP):
The SWPPP was complete and contained the necessary elements for stormwater
pollution prevention. All stormwater outfalls were identified in the SWPPP and were
adequately documented on a site map. Outfalls 001, 004, 006 and 007 are not currently
monitored individually as they have representative status with other designated outfalls.
These outfalls With representative status should be specifically identified with the
appropriate analytical data to support the representative outfall designation.
The facility should provide the Division of Water Quality with such information for
verification of representative outfall status. Should such information not be available,
the facility should conduct the appropriate analytical testing of these outfalls and submit
all results to the Division of Water Quality.

4. Vehicle/Equipment Maintenance Area:
Not Applicable.
5. Vehicle/Equipment Wash Area:
Not Applicable.
6, Temporary Storage of Waste Materials:
Waste materials appeared to have secondary containment. Please be sure to check all
secondary containment areas daily for possible overflow situations. During the
inspection, one of the secondary containment structures in the silane production area
associated with one of the boilers was close to overflowing. The facility addressed this
issue at time of visit to have the area pumped immediately.
7. Outdoor Storage of Materials:
Materials stored outside appeared to be in poly totes with reinforced cages. There did not
appear to be any evidence of leaking containers.. Dry materials are stored in buildings to
prevent exposure to the elements.
S. ' Spill Res onse and Cleanuv Pro ram:
Adequately addressed.
9. Erosion Control on Site:
There were areas that need to be looked at for erosion control such as the area up gradient
.from the chemical storage area. Runoff from up gradient seeps through the wall surrounding
the chemical storage area and runs across the storage pad floor. The facility indicated the area
located up gradient from the storage area would be re -graded to eliminate runoff collecting in
the storage pad area. Areas around the Duck Pond are also graded to reduce the effects of
erosion.
10. Illicit Discharge Elimination:
Not Applicable.
11. Wastewater Treatment Facilities:
Wastewater treatment is not required at this time.
12. Stream Impacts/Results of Sampling:
Compliance sampling was not conducted during the inspection.
13. Summary:
The SWPPP was. complete and contained the necessary elements far stormwater
pollution prevention.
The Division has two concerns however that needs to be addressed immediately:

2. The facility should review the Stormwater Pollution Prevention Plan and current standard
operating procedures in all areas, especially areas involving materials handling operations,
to identify any areas that may be improved. The facility should implement the appropriate
changes in an effort to improve current practices and reduce stormwater pollution. The

The overall condition of the plant site was satisfactory. The appearance of the facility was in
acceptable condition indicating that the current housekeeping practices are fair.
Upon inspection of the monitoring results for stormwater discharge from Outfalls 002, 003 and
OOS; the concentration of pollutants discharging through the stormwater outfalls are excessive
and significantly higher than should be expected (See attached "Summary of Storm Event
Monitoring'). The data presented in the "Summary of Storm Event Monitoring" indicates
concentrations of BOD, COD, TSS, NH3, TKN, Formaldehyde and Hexamine are excessive for
stormwater discharges. The facility indicated that it was difficult to control the accidental
transport of dry chemicals by personnel 's feet and forklift wheels in areas where dry chemical is
being stored and handled. As specified in the current permit, this monitoring data is evaluated
against the "cutoff levels " presented in the permit. The concentrations of various pollutants
were significantly higher than the corresponding "cut-off level " which indicates that substantial
improvements in housekeeping, material handling, and containment are needed.

Reference: Wright Corporation Facility inspections
NPDES Permit Nos. NCO003395 & NCS000156
Dear Ms. Willis:
ISO 9002 Certified
This letter is in response to NPDES inspections that were conduct at the Wright Corporation
(Wright) site on March 16, 2005. The inspection covered NPDES Permit Nos. NCO003395 and
NCS000156.
Discussion for NPDES Permit No. NCO003395
The following discussion is based on the items in Section D: Summary of Findings/Comments in
the inspection report for NPDES Permit No. NC0003395.
Item I - Permit:
Wright Corporation was aware of the Special Order by Consent (SOC) agreement. The facility
has a copy of the SOC signed by Mr. Thomas Wright, however, at the time of the inspection the
SOC had not be approved by the Environmental Management Commission (EMC). Wright
received a letter from NCDENR on May 18, 2005 providing approval of the SOC by the EMC.
Wright plans to take whatever action necessary to comply with the provisions set forth in the
approved the SOC.
Item 9. Pretreatment:
The facility influent stream is 100% industrial.
Item 10. Solids Handfing/Disposal:
The solids that are generated in the wastewater treatment system are periodically discharged into
permitted storage ponds at Wright's facility.

Discussion for NPDES Permit No. NCS000156
The following discussion is based on the items in Section D: Summary of Findings/Comments in
the inspection report for NPDES Permit No. NCS000156.
Item 2. Facility Site Review:
Wright is in the process of reviewing the StoTmwater Pollution Prevention Plan and current
standard operating procedures in order to identify any and all areas that can be improved to f f
minimize contamination to the stormwater. Wright has in the past and will continue to monitor —'
the surface waters both upstream and downstream of the facility. To date, the analytical results
from sampling events have not indicated there has been any impact to the surface water due to
Wright stormwater discharges. Wright takes stormwater seriously and will make the efforts
necessary to minimize the facility's impact on stormwater.
Item 3. Adequacy of Stormwater Pollution Prevention Plant:
Wright is working on obtaining the appropriate analytical data to support the representative
outfall designation for Outfalls 001, 004, 006, and 007. Wright expects to submit the analytical
data and supporting information to NCDENR within the next 2 months.
Item 6. Tempprar, Sto e of Waste Material:
The secondary containment for the fugitive scrubber in the Silanes production area is designed to
overflows into another containment area before it exceeds maximum capacity.
Item 9. Erosion Control on Site:
Wright is looking at the chenucal storage area to determine the best way to eliminate/minimize
runoff from up gradient seeps. Re -grading the area up gradient of the chemical storage area may
not be possible because it is on the slope of a landfill. Wright is currently working on erosion
control around the Duck Pond.

Linda,
Limits in stormwater permits are tricky. We've begun incorporating "benchmark"
concentrations with renewals this cycle and put language in all permits that require
permittees to evaluate the effectiveness of their BMPs when their monitoring results
are above the benchmark --and that they revise their SPPP if necessary AND document
their efforts to reduce contamination.
we realize that it is not the strongest thing we could do, but it is an important
change from previous permits. One of the problems with formulating actual "limits"
on stormwater discharges is that we don't have a very good way of setting
them... wastewater discharges are typically continuous, and Nc's approach is
well-defined in calculating loading with flow capacity and worst -case low flow
conditions of the stream to which it discharges. .An a rain event, not only is the
discharge itself highly variable, but is using something like the 7Q10 flow really
appropriate? Anyway, that's one of the biggest challenges to finding a methodology
that's defenisble as a limit.
BUT, all that being said...I happened to work on a stormwater permit renewal for a
resin manufacturer just recently that has a spray irrigation treatment requirement
when thresholds for two parameters (one being formaldehyde, incidentally) are
exceeded in their stormwater detention pond samples. so, essentially, they have a
"limit" that prevents them from discharging stormwater from the pond directly to the
stream and are required to route it to alternative treatment. I don't know all the
history to it, but at some point there were lawyers involved, so I gathered it wasn't
a simple evolution of the permit ... but I do know that the region (it happened to be
Raleigh several years ago, I think) pushed hard for this more stringent requirement
for years.
Given the situation at this site, I will definitely consider our options and your
recommendations as 1 go through the renewal review for this facility. I'm also going
to work with Danny Smith on this one. I saw the name on the folder and knew this was
going to be a difficult one long before you called back in March ... maybe we can
design something that is appropriate; justifying the approach will be key.
I'll definitely be in touch as I work on it.
Thanks and have a great weekend,
BG

added it to my files.
We've been working through all our permit renewals in the order that they
expired (there was already a pretty bad backlog when I started last year), and
Wright is literally next on my list. It has the added complication of having
formaldehyde monitoring, which we are still trying to establish a firm
"benchmark" for, but we should have a good number in the next couple weeks.
Because I'm also coordinating the training workshop happening in November for
all you guys, I'm going to be pretty tied up with that for the next month, so I
probably won't get Wright's- permit drafted until later November. I also talked
to Mark McIntire about his wastewater permit adventures with them before Mark
left for another job back in September, so I got a little background on that
side.
Anyway, I just wanted to catch you up on the status. If you have any
questions, just let me know. In light of compliance issues at the site, I'll
be sure to consult with Danny Smith when I work on it.

Hi Linda,
Hope you had a great Thanksgiving. I've finally gotten to work on Wright

to Wright on May 3?

supposed to be doing up- and downstream monitoring of DO. I tried to find those
results in the DMR files but didn't see them...? I was curious about what upstream
'natural' conditions are there (they discharge to swamp waters) and wondered
whether requiring up -and downstream DO monitoring in conjunction with their
stormwater discharge would be something to consider --especially seeing those BOD
and COD levels they're discharging in rain events. I'm not sure if this is the way
to go, but given that we're dealing with a stormwater permit that would not
normally have limits, trying to ascertain if stream standard violations occur could
be important.
Unfortunately there is no current WQ standard in NC for hexamine or
formaldehyde ---these could have also been good instream parameters I think.
It's a little more complicated because it looks like their WW discharge is also at
outfall 001, so I'm not sure if instream monitoring will be as reliable for SW
discharge impacts.
Thanks,

Bethany,
I will forward to you, their response to our NPDES Stormwater inspection as well as
the RO's inspection report. In the response, Wright said they would provide us data
to support the representative outfall status, that, I don't believe has been received
yet. I cannot find it in our files. That should be requested before we allow the
continued representative outfall status to stand as is. I believe, given the
contamination in the stormwater, sampling at all outfalls is prudent. We can allow
the data to speak for itself, but we must see the data first. I think you are on the
right track with considering DO monitoring, also, toxicity testing may not be a bad
idea since ammonia nitrogen is toxic to fish in very low concenrations (literature
says 0.05 mg/L NH3-N (unionized form), pretty low). Literature also states that 30%
of ammonia nitrogen remains in the unionized form at pH greater than 8.75. Look at
the Summary of Storm Event Monitoring Chart (SEM Chart) [I'll send that in interoffice
mail today) and you'll see the pH is above 8.75 on 6 different occassions. Also pH
ranges that change 2 units or more are harmful_ And those types of swings are also
seen on the SEM Chart. Estimated volume of water for rain events between 03/16/2000
and 02/03/2005 range from 0.007 to 0.200 MG. Those flows to creek will most certainly
have an impact around the vicinty where the outfalls discharge. Maybe it would be
prudent to take a hard look at the dilutive ability of the receiving stream. Also,
for every pound of ammonia nitrogen that gets converted to nitrate nitrogen by the
nitrifiers, 4.6 lbs_ of oxygen is consumed. So, during the rain event on 9/18/2000,
the flow was 0.122 mg. NH3-N = 645 mg/L = 656.2 lbs. of NH3-N that can consume 3018
lbs. of oxygen; add that to the oxygen requirement to biodegrade 385 mg/L BOD (391
lbs BOD) and 2,740 mg/L COD (2788 lbs COD) and you have a total oxygen demand of 6197
lbs of oxygen potentially consumed as a result of that rain event at the facility.
Keep in mind, I didn't pick the worse numbers to crunch these figures either. I have

Re: Wright Corp. SW permit
not sent any other requests to Wright other than to beef up their BMPs immediately to
address our concerns.
I'm available to speak with you any time Bethany and look forward to our tackling this
very troublesome situation. Our stormwater permit as you can see, does not adequately
nor effectively address the situation we have with this facility.

Forgot to reply to the DO, conductivity and temperature, upstream downstream
sampling. They haven't been sending that information in. Realistically, not many do
send in the upstream/downstream monitoring reports. I was asked by my Regional Super
at one time if we were enforcing those limits, I had to tell him no. I don't think
any region has. It would be great if that data (upstream/downstream) would be
entered into BIMS so that the River Basin planners can use that data. By the way,
their NPDES permit doesn't give DO limits in the language. I'll be sure that gets
remedied in the next permit renewal.

Re: [Fwd: Re: Hexamine benchmark]
A follow-up to the information I went over with you this morning. The
stormwater benchmark (1/2 Final Acute Value of 4.98x107 ug/L ) is 2.49x107
ug/L or 2.49x104 mg/L. This is based on very limited data from the source
PAN Pesticides Database (www. esticideinfo.or ). This criteria could
change if more data can be obtained in the future.

Hi Matt,
I'm working on the stormwater permit renewal for Wright Chemical in Riegelwood, and
both our office and the Region have raised concerned about the levels of BOD, COD,
and ammonia this site has been measuring in their stormwater discharges.
Attached is a copy of the analytical data (wright_analytical.pdf and my excel file,
which summarizes the data). Although overall it seems levels have improved
somewhat over the permit term, measured levels are extraordinarily high in some
Cases (ammonia levels well above 400 and 500 mg/l; COD in the 1000-2000s mg/1).
This obviously raises a toxicity concern, and we're wondering how to best address
it in the renewal permit. The effects on DO are a concern but are a little more
tricky because the discharge is to swamp waters (C-Sw); the ammonia levels seem
toxic no matter how you look at it.
A little background first on what we've been doing this past year with our other
industrial stormwater permits. We're incorporating "benchmark" values that are not
limits, but are instead a guide for the permittee to examine their stormwater
management plan and practices. These values are typically based on the acute
effects on aquatic life (when info is available), given the nature of stormwater
discharges, and the permittee is required to document what he/she has done to
address potential problems when they are exceeded. Benchmark values and info. are
in the spreadsheet I've attached (and we continue to refine our list with Connie
Brower and Jason Wynn's help) .
Having benchmarks in the permit will be a big step, but chances are very likely
they're going to blow them routinely based on past data, and the Region doesn't
sound convinced that this company is doing all they can to prevent potential
contamination of rainwater.
So, that brought us to the question of whether a toxicity testing requirement
would be appropriate in this situation. I was only familiar with the Acute -
Episodic testing required in our S/W permits for airports because of de-icing fluid
discharge. When I did some searching to find out if other states used toxicity
testing in stormwater permits, it is cited primarily as a monitoring/screening tool
rather than "compliance" tool (unless the stormwater is actually considered a
process wastewater... not sure how easy it would be to argue that in this case if
it's just sloppy housekeeping). So, our question is really this: would requiring a
Tax Test in this permit really get us anywhere (i.e., our "only" way of determining
if water quality standards are being compromised in the receiving waters), and if
so, what rationale do we use to justify it in a stormwater permit? [I was scouring
the red book for ways to link toxicity to our water quality standards, but it is
usually referenced in conjunction with "effluent" or "effluent limits." One
dilemma we face is that simply saying stormwater is "too dirty" doesn't make it a
wastewater... but our permits specifically do not allow water quality standard
violations.]
Attached for your information is also (1) a copy of the inspection letter from
Linda Willis at the WiRO, (2) Wright's response to that letter, and (3) a topo map
of the site (you may already be familiar with it) --it's situated in the center
where it says 'Acme'.
Whew! I know that's a long (complicated) question. Do you have any thoughts or
advice about whether a toxicity testing requirement would benefit us in this
situation?
Thanks so much for your help,

Re: Toxicity Testing and stormwater Permits
Bethany
Bethany,
I did receive your message regarding Wright's situation with the discharges of the
stormwater vs their NPDES WWTP discharge. The WWTP outfall and stormwater outfalls
goes to a swampy area that interconnects both Livingston Creek and Mill Creek. The
upstream downstream sampling would have the influence of all wastestreams from the
site (NPDES WW discharge and stormwater outfall discharges). Livingston has the
influence from IP as well. Upstream/Downstream sampling could be required in the
stormwater permit can't it?? For let's say BOD, COD, N H3-N, and TKN along with DO,
Conductivity and pH. The last permit cycle (permit i ssued Feb, 2000) there was no
mention of representative outfall status granted or acknowledged in the text of that
permit. Correct me if we have granted them that. In my last inspection report I
asked for the data showing supporting evidence that outfalls 1, 4, 6 and 7 were
granted represent. outfall status. I did not receive anything from Wright. Can you
all look through your records to see if that was granted?
Here's what we'd like to see (I visited a little bit with Ed Beck on this). . Ed did
say that since this is an individual permit, we should be able to modify it anyway we
deem appropriate and effective to fit the situation at Wright.
1.) Require all outfalls be monitored fully including BOD, COD, NH3-N, TSS, TKN, TP,
pH , formaldehyde, hexamine, (lead had a hit above cut off levels in 2002) not sure if
you want that one to stay in. We need to know what the situation is at all the
outfalls (let's hope they are not representative because that would truly be bad for
2Zall the outfalls to be so heavily contaminated) and I think if some of those outfalls
( had been given "representative outfall status" that needs to be eliminated. Also I
recommend toxicity testing for each outfall once per year (to get a baseline). if
they pass "X" (not sure what is reasonable for "X") number of sampling events in a
row, they can be given the flexibiilty of not testing again until the last year of the
permit (perhaps). Maybe in lieu of toxicity at the outfalls, we have them do
.yq upstream/downstream monitoring for every parameter on their NPDES WW Permit
(NC0003395) including COD.
2.) This is the second permit round that we will (most likely) see the stormwater
from the site bust cut off concentrations. Housekeeping has been addressed in their
BMP's yet they admit housekeeping remains a problem which they cannot seem to find
solutions for (hexamine storage area for example). Our language in the new permit
should keep cutoff concentrations as a benchmark that if exceedances continue. . the
Division will be looking for action from Wright to resolve in an expedient manner.
give them a time schedule to address the problem once the cutoff concentration has
�een exceeded. Require them to write a report to us telling us why the contaminants
were so high and what they are doing to resolve the issue. If tightening up on
housekeeping works, fine. If not, we should require that Wright capture the on site
$ run off (in those areas feeding the outfalls that are above cut off concentrations) -
and treat it as a wastewater. Let's keep in mind, the i-r BOD loading to the receiving
stream from stormwater runoff (if you crunch some numbers) are a magnitude of 10 to 60
times higher than their NPDES WW BOD limits!
Industrial sites are tough, we have a few throughout our region. Many of those
capture their stormwater in their processing and storage areas and treat it onsite as
a wastewater. Granted, they probably use it for dilution of their process wastewater
and therefore happy to run it through their WWTPs. None the less, it does not leave
the site with stormwater. Wright may have to consider their stormwater a wastewater
that should be treated if they cannot resolve these issues.
Thanks for the update Bethany. We are all ears here and look forward to working with
you all on this one. Perhaps you all would like to go visit the site?

Linda Willis

Yes - their NPDES permit is assigned to Bob Guerra in the NPDES East Unit. From the
history I know, Mark McIntire (who used to work in that Unit) went through a very
unpleasant settlement negotiation (they adjudicated their last wastewater permit) to
get to that endpoint ... it was pretty messy. Not sure what Bob is doing this time
around (and we should coordinate)... but it makes our stormwater permit task even more
challenging_
What's so difficult about limits on stormwater is that there is no established way to
calculate them... the rules specify that 7Q10 conditions (or 30Q2 flow, depending on
whether its a carcinogen) are used for ww effluent limits, which are for a continuous
discharge. However, there is no set method for calculating WQ-based stormwater
limits, and the 7Q10 (low flow) basis doesn't make sense because it will not be a "low
flow" condition in a rain event. That's not to say there shouldn't or can't be any in
a stormwater permit (and yes, we can make a sound legal argument that we have the
authority to impose them), but at the moment we're at a loss for a defensible method
to calculate them. You do make a great point with the construction site example,
though --that may be helpful here.
There's no doubt that we cannot justify giving them a stormwater permit that
essentially permits discharge of wastewater. And that at the numbers we're seeing, we
may have an excellent argument that stormwater must in fact be contacting enough raw
material to be considered a process wastewater --which means it's not stormwater. I
need to sit down with Bradley and discuss some approaches, especially in light of
Matt's thoughts on the toxicity testing. I'll let you know what he says.

Re: Wright
Linda,
I got your message this week and just didn't have a chance to get back to
you on this - I did speak briefly with Matt, and basically he said it is
not a problem to require toxicity monitoring (and agreed the numbers
looked pretty bad), but we must think ahead to what our long-term steps
will be if they fail actue tox tests... require other BMPs, additional
treatment, route to wastewater, etc.? We have the authority to do that,
we just need to choose our strategy. We can even issue the permit for a
shorter period of time than 5 years, but again, we need to have a good
idea of what would be next, particilarly if there is any legal challenge
in the future. Bradley even suggested working with NPDES wastewater on
this one, and in fact, that permit may be up for renewal shortly, too.
I'm hesitant about requiring instream monitoring in the stormwater permit
if the wastewater discharge introduces influence because the data could be
difficult to use ... but then again, if they're complying with the
wastewater limits, their ww shouldn't violate water quality standards in a
worst case low flow condition, and therefore not in a rain event that
increases stream flow --so it might still be worthwhile; it just may be
more of a safety issue at times for their employees in storm conditions.
No, I haven't seen any information granting their representative outfall
status (but I'll comb the files again), and I intend to ask the contact if
they've submitted that info. per your request. Obviously not yet...
Okay, we'll talk more soon. Thanks,

Re: Wright
Comments on Wright Corporation
Look at NC General Statute 143-215.1(a)(4), (6) and (al). No person shall
do any of the following. _
(4) increase the quantity of waste *discharged through any outlet* or
processed in any treatment works or disposal system to any extent *that would
result in any violation* *of the* eflfuent standards or *limitations
established for any point source* *or that would adversely affect the
condition of the receiving waters to the extent of violating any applicable
standard . *
(al) *in the event that both effluent standards or limitations and
classifications and water quality standards are appicable to any point source
or sources and to the waters to which they discharge, the more stringent
among the standards established by the commis shall be applicable and
controlling.
*This says to me that we can impose effluent standard limitations on the
stormwater discharge no less stringent that that of their NPDES Individual
permit since their are no water quality standards for ammonia or BOD but
their are effluent standards for that receiving stream from this facility
from a point source.*
*
Looking at 143-215. *The Commission is authorized and directed to develop,
adopt, modify and revoke effluent standards or limitation* and waste
treatment management practices *as it determines necessary to prohibit abate
or control water pollution*. *The effluent standards or limitations
developed and adopted by the commission shall provide limitations upon the
effluents dishcarged from* pretreatment faci litites* and from outlets and
point sources to the water of the state adequate to limit the waste loads
upon the waters of the State to the extent necessary to maintain or enhance*
the blah blah blah
We can, should and are directed to impose limits, not just cut off
concentrations. . .
Looking at this Bethany, why can we not put limits in their NPDES Stormwater
Individual Permit to accomplish what we are directed here to do. We limit
their wastewater effluent for BOD, and NH3 as N at levels far below that
discharged with their stormwater. We have the power to put limits
(enforceable) in their stormwater permit as stated above don't we??? If
their WW permit deems NH3-N and BOD levels as applicable standards for their
discharge, how can those levels not be "applicable" to their stormwater
discharge??
They must be sure their stormwater effluent is no more polluted than the
effluent limits given them for their treated process wastewater. I€ they
cannot prevent contaminants from being in contact with the stormwater, they
should have to treat that as a wastestream. It has all the characterisitics
of a wastewater not just what we typically see as stormwater runoff. The
regs above state our ability to do this. I believe we need to put BOD and
NH3-N limits no less stringent than what is in their NPDES WW permit . We
have a construction site here in town that is contaminated with urea. When
in contact with stormwater, the runoff becomes a fairly concentrated
wastewater of ammonia. . to the tune of 50 ppm to 40000 ppm. We issued two
NOV's for discharging ammonia to the stormd r ains. Although we had no stream
standard limits for ammonia, it is a constituent that has limits on NPDES
discharge permits and in the tune of 2 and 4 ppm (depending upon season). .
on that premise we stated that no ammonia can -leave their site via stormwater
runoff or stormdrains to surface waters in concentrations greater than that.
Wright's situation is no different. The ci t ed'facility brought in an on site
WW treatment system to treat the ammonia below 50 ppm in order to send it to
the City of Wton's WWTP, not until they get below concentrations of 2 and 4

Re: Wright
are we able to allow them to let it "runoff" to the river. Water quality
standards only address a specific list of contaminants or conditions. . it
doesn't encompass everything. The regs allow us though to impose beyond
water quality standards (which misses a lot of stuff) by allowing us to use
either effluent limitations that would be applicable for a discharge, or the
water quality standard or when both come into play, the more stringent of the
two.
As I see it, we must force the issue of adherence to no more than 2 and 5
monthly limits and 14 and 25 daily max's (right in line with their effluent
permit) which goes to the same receiving stream. We cannot be any less
stringent on this source of contamination (even though stormwater related)
than that issued for the point source effluent WW discharge. Same goes for
BOD.
Well that's my argument for this situation. Perhaps I'm missing something
but, I think we have two legs to stand on concerning this particular site and
it's obvious stormwater contamination problems.
I look forward to your response.
Linda Willis
I already sent a list to him, so he's good to go. . . Tom Moore may come along, T
told Tom I'd have to put him on the list so he'll have to give me an answer by
tomorrow at least.
By the way, I was wrong, Wright has BOD mass limits (12.8 and 34 lbs) monthly/daily
respectively. . but not NH3 limits_ _ they have a really relaxed permit (NPDES
Individual) since that's coming up for renewal, let's talk about their NPDES Permit
renewal limits too.

som3,t,ilfie the 14th (monday). I am in the field with Bob Sledge at Cogen Monday but
uld be in the office some.

Let's investigate the option for them to treat that stormwater as wastewater. We
should schedule a conference call with Bob on the topic and discuss this one.
Take Care Bethany,
Linda
Bethany Georgoulias wrote:
Yeah, I talked with Bob about that and got the feeling that treating the S/W with
their WW was something they thought could be done effectively. I'm not sure what
Tom Moore thought.
I am also booked pretty solid through August (vacation next week, and GIS training
the entire last week of Aug), so September will be the earliest chance I'd have,
too. By the way, I started looking at the calendar, and while Christmas is a long
way away... the last window I have to send permits to notice and be able to issue
them before my maternity leave will be late September/early October. At the very
least, I'd like to make sure we get the Port Authority's permit sorted by then.
I'm not sure if we can swing Wright's permit by then, but I'm certainly willing to
try. Otherwise, I won't be able to pick this stuff back up until April, and
depending on our efforts to coordinate with the WW permit, it may have to go to
another staff member in my absence.
Are we still on for 1 PM today to talk about Shelter Creek? I looked through the
package earlier this week and am hoping to get Danny's help before this afternoon
as well. Regardless, I'm planning on being available for that discussion.
Talk to you soon,
Bethany
Linda Willis wrote:
Bethany, I had given Bob a copy of the spreadsheet showing the outfall data
from Wright's stormwater sampling. I hoped we could get their stormwater
outfalls incorporated in their npdes permit and require treatment of that
"wastewater". I still feel that this site's problems are atrocious compared to
any other permitted site we have. Something needs to be done, and so far BMP's
haven't solved their problems. It doesn't sound like permitting is up to
1 of 3 10/5/2006 3.16 PM

Re: Email response from Wright Corporation
tackling this through their NPDES ww permit. This one would be a good one for
you to come visit. Let me know. . . I'm in no huge rush as I'm up to my
eyeballs in permit renewal site visits until Sept.
Thanks for the insight on this my friend and hope you are doing well and feeling
good.

Bob,
As we discussed, I don't mind your forwarding information that may be helpful
for Wright in improving their stormwater BMPs. If you'll please also let Ms.
Oscarson know that she should work with the Stormwater Permitting Unit if she
needs additional assistance on stormwater BMPs, we'd appreciate it. Please
let her know BMP changes at the site may be something we'll want to work with
her on through the stormwater permit renewal process, and that we'll
coordinate with the WiRO on that.
Thanks for sharing the info. from your site visits,
BG

Ms. Oscarson is the Environmental Manager who took Tom Moore, Deborah Gore
and myself on a site tour of the Columbus County POTW and the Wright
Chemical Facility. During the site visit technical assistance was offered
by providing Stormwater BMP's. I have complied eight BMPs and other
information to assist her, if she desires, to implement a Stormwater BMP
at Wright Chemical. I have spoken with Bethany and she has no problem
with me providing the information. Of course I will not favor one over
the other or recommend one as well. If everyone is comfortable I will
email these today. If it is decided that Bethany should provide this
information I will give it to her to send.

Hi Bob,
This is my email address- please send the storm water SMPs to this
address. Also, I am sending to you by certified mail a POTW status
report, I believe it is due August 15, and I f1 gored it should be
addressed to you since you are the designated permit writer for our POTW
and our Biotrol system. I am going to cc: Alan Klimek as well, just in
case it is to go to the general DWQ office.
Thank you!
Karen

The 9th sounds good. Are we scheduling with Rachel for the site visit, (whose number
I don't have) or are we scheduling with Karen Oscarson (or both?). Let me know who
needs to be there (besides you and I) and if I should schedule through Karen or we
simply let Rachel know we're hoping to schedule a site inspection on the 9th.
Thanks

Linda,
I'd like to attend that meeting after having visited the site. Any chance we
could schedule a site visit before the meeting? So, I guess I'm asking if we
could schedule a site visit during the first week of the year. I'm ok for a
meeting on the 9th or during the week of the 9th. But, I'm planning vacation the
week of January 15th, so, as far as the stormwater permit goes, I don't want to
delay if I can avoid it.

Hi Agyeman,
I'll be out on maternity leave and won't be back until mid- or late -March,
so I'll leave it to Ken to coordinate with you guys on that meeting. I know
he had been planning to schedule a site visit with Linda Willis in January.
She'll need to be involved as well (and I think she's out until after
Christmas) since she's been the region contact for stormwater.
Thanks,
BG

Hi there,
Rachel Whittier, O'Brien_ & Gere called back this morning that Hexion
Specialty Chemical will like to meet with both NPnES Wastewater and
Stormwater staff to figure out a way forward for both their Wastewater
and Stormwa ter permits. She proposed a meeting for January 9th. Susan
Wilson suggested this meeting should be held at the Wilmington Regional
Office. In a phone conversation with Tom Moore, he concurs with that
idea. Tom is coordinating the meeting with his staff. Please let me know
if the date will work for you. Also since we will be traveling to
Wilmington, what time works best for you?
Thanks Agyeman

Ninth hour update on Wright Chemical (since I'm still here!) ... you may
already know some of this, but just in case:
I talked with Agyeman Adu-Poku this morning about our visitor
yesterday who was looking for the Wright Corp. files. A
representative from O'Brien & Gere (I think?) Environmental Consulting
Firm stopped by our office to get copies of the NPDES Wastewater and
stormwater permits. Apparently Wright Chem has been bought by Hexion
(?) Chemical, and the transfer of ownership was effective December
1st. Hexion has hired O&G (the rep. was named Rachel) to look into
the environmental issues for them, so they were interested in what
Wright has and hasn't submitted thus far for their permitting
requirements.
Agyeman said NPDES is still waiting on additional information that
hasn't been submitted and can't proceed with renewal until then. I
believe Linda requested info./data on representative stormwater
outfalls well over a year ago that she never received either. Agyeman
said the company and consultants will want to meet with all of us soon
to understand what's outstanding, so it would be a good opportunity to
coordinate the wastewater and stormwater side of things at this site.
Ken, because some benchmark values in Connie's latest table are still
pending revision (one of them being exactly what value to use for
ammonia, which will be especially relevant at this site), if questions
about that arise before I get back, be sure to consult with Connie
Brower on specific parameters.
Perhaps this is another opportunity to have the company consider
alternative approaches and treat their contaminated stormwater...??
Just wanted to get everybody in the loop. Thanks, and happy
holidays!!

Samples are collected three times per week on three separate calendar days.
Act or "the Act"
The Federal %Vater Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC 1251, et. seq.
Annual Avemge
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
conform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
The known diversion of waste streams from any portion of a treatment facility including the collection system, which
is not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Quarter
One of the following distinct periods: January through Burch, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period- The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case -by -case basis- Samples may be collected 'manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time internals over a 24 hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1 /24 of the
expected total daily flow at the treatment system, or
(a) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval- This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.

NPDES #. NCO087497
Dear Mr. Varner -
The PPRCS Unit of the Division of Water Quality acknowledges the receipt of the signed
Industrial User Pretreatment Permit (IUP) issued to the following Significant Industrial User
(SIU). This signed IUP was received by the Division on August 2, 2006_
IUP #
SIU Name
001
Oak -Bark Corporation d.b.a. Wright Corporation
This HUT was previously submitted in Draft form and was found to be adequate to meet the
minimum requirements of 15A NCAC 2H .0905 and .0916 and 40 CFR 403.8(f)(1)(111) as per
Division correspondence dated June 28, 2006.
The Division is concerned that the entire flow and calculated pollutant allocation for this POTW
has been permitted to one industry. This leaves no allocation for future commercial and
industrial growth or domestic flow from the surrounding area. Not allowing for other users does
not appear to be consistent with the Federal definition of POTW.
A copy of your allocation table is attached for your files. Please note that until the Short Term
Monitoring Plan can be implemented, there is no basis for the cyanide, lead or zinc limits. These
limits may have to be modified based no the results of the Headworks Analysis.

Federal and State pretreatment regulations require the local delegated pretreatment program to
effectively control and document the discharge of wastewater from Significant/Categorical
Industrial Users to the POTW. It is the POTW's responsibility to ensure that these objectives are
consistently met.
Thank you for your cooperation with the Pretreatment Program. If you have any questions or
comments, please contact Deborah Gore at [phone], ext 593 [email: Deborah.Gore

Subject: Renewal of Permit Number NC0003395
Dear Mr. Klimek:
This letter is to request renewal of Permit n NC0003396 issued to Wright Corporation on
September 30. 2003, Which expires on December 31, 2006. This permit covers the discharge
from the "Biotrol" wastewater treatment system to Livingston Creek (Discharge 001) and the
discharge of blowdown from the cooling towers to Livingston Creek (Discharge 002). The
discharge through the Biotrol has historically been both the process wastewater and the
blowdown from the plant boilers. In July 2006, Columbus County POTW (NC 0087947) will
begin start up operations. During this time of acclimation some of the processed waste will
continue to be discharged to the Biotrol as necessary to optimize the start up of the Columbus
County POTW_ During this time, all wastes discharged through Discharge 001 will meet the
final effluent limits in the original permit, due to the Special Order by Consent expiring on July 1,
2006. The attached application for permit renewal presents the expected flow and pollutant
loading for Discharge 001 after the process water is removed and the Columbus County POTW is
fully operational_ A copy of both the original permit and the SOC are included for reference.
The discharge of non -contact cooling water to Discharge 002 will continue. This is reflected in
the application as well.
Another reason for renewal of permit ## N00003395 is to have a back up plan for the POTW if it
fails. The intent is to phase out using the Biotrol system while phasing in the POTW for
processing our industrial wastewater. However; in the unlikely event of malfunction and
shutdown of the POTW, an alternative should be in place for processing
the 0.1 WD of wastewater that would continue to be generated by Wright Corporation_
Thank you for your consideration
Sincerelv,
G

five (5) days following first knowledge of the occurrence. This report must outline the actions taken
or proposed to be taken to ensure that the problem does not recur.
IV. GROUNDWATER REQUIREMENTS
I. Sampling Criteria:
a. Monitor wells MW-22, MW-23, MW-25 and MW-26 shall be sampled every January and July
for, and monitor wells MW-6, MW-7 and MW-9 shall be sampled every March, July and October
for the following parameters below:
Water Level
pH
Total Ammonia Nitrogen
Total Dissolved Solids (TDS)
Sulfate
Volatile Organic Com ounds
Total Organic Carbon (TOC)
Nitrate (NO3)
Formaldehyde
' Sampled in June only
2 Sampled in monitoring wells MW-6, MW-7, MW-9, MW-23 and MW-26 only
Note that prior to sampling for the above parameters, the measurement of water levels must be
taken_ The depth to water in each well shall be measured from the surveyed point on the top of
the casing. The measuring points (top of well casing) of all monitoring wells shall be surveyed
relative to a common datum.
b. For Total Organic Carbon (TOC), if concentrations greater than 10 mg/l are detected in any down
gradient monitoring well, additional sampling and analysis must be conducted to identify the
individual constituents comprising this TOC concentration. If the TOC concentration as
measured in the background monitor well exceeds 10 mgll, this concentration will be taken to
represent the naturally occurring TOC concentration_ Any exceedances of this naturally
occurring TOC concentration in the down -gradient wells shall be subject to the additional
sampling and analysis described above.

c. For Volatile Organic Compounds (VOCs) sampled in July, use only one of the following
methods:
Standard Method 6230D, PQL at 0.5 µg/L or less
Standard Method 6210D, PQL at 0.5 µg IL or less
EPA Method 8021. Low Concentration, PQL at 0.5 µg /L or less
EPA Method 8260, Low Concentration, PQL at 0.5 µg IL or less
Another method with prior approval by the Groundwater Section Chief
Any of the referenced methods used for VOCs must at a minimum, include all the constituents
listed in Table VIH of Standard Method 6230D. Any method used must provide a PQL of 0.5
µg IL or less, which must be supported by laboratory proficiency studies as required by the

Subject: Permit No. WQ0005699
Wright Corporation
Riegelwood, NC Manufacturing Facility
Surface Disposal of Residual Solids (503 Exempt)
Columbus County
Dear Mr. Smith:
In accordance with your permit renewal application package received on July 17, 2001, we are
forwarding herewith a renewed Permit No. WQ0005699, dated February 17, 2006, to the Wright
Corporation for the continued operation of a surface disposal unit at its Riegelwood, NC Manufacturing
Facility.
This permit shall be effective from the date of issuance until January 31, 2011; shall void Permit
No. WQ0005699, issued on October 11, 1996; and shall be subject to the conditions and limitations as
specified therein. Make dote of this permit's expiration date and the fact that a permit renewal application
is due to the Division of Water Quality (Division) no later than six months prior to that date (i.e., see
Condition VJ. 8.), as the Division does not send reminders to apply for permit renewal. It should be
noted that the package submitted to apply for this permit renewal was submitted only three and a
half months before the expiration date of the previous issuance of this permit (i.e., submittal date of
July 17, 2001 versus an expiration date of September 30, 2001). It is a permit condition that a
permit renewal application package be submitted on time. The Permittee should make a better
effort to monitor permit expiration dates in the future to avoid potential enforcement action for
failing to submit a timely renewal as well as operating the residuals land application program
without a valid permit.
This permit approves the continued operation of the surface disposal unit for another five-year
permit cycle. Please take the time to review this permit thoroughly as many of the conditions
contained therein may have been added, changed, or deleted since this permit was last issued. Pay
particular attention to the monitoring requirements in this permit. Failure to establish an adequate system
for collecting and maintaining the required operational information will result in future compliance
problems. Of special interest to you may be the following:
♦ Condition 1. 1.: This condition requires that a signing official delegation letter be submitted
to the Division .within 30 calendar days of permit issuance.

♦ Condition I. 2_: The construction/operation of water supply well within the compliance
boundary of a permitted waste disposal system is a violation of 15A NCAC 2L _0107 (d).
During the site visit by the Aquifer Protection Section of the Division's Wilmington Regional
Office, it was noted that there are wells located within the compliance boundary of the
surface disposal unit that are being used to supply process water for the chemical
manufacturing process. This condition requires that these wells be labeled as "non -potable"
and be verified for compliance with the well construction standards within 90 calendar days
of permit issuance. Further action is required if the wells are not in compliance with these
standards.
Finally, the Division would like to offer'a special note of caution in that, typically, conditions
related to freeboard monitoring and maintenance are added to permits in which the surface disposal unit
being operated is of a lagoon/impoundment type. At this time, the Division has decided to forgo these
requirements in the permit because the unit is rarely used, is covered to prevent stormwater intrusion as
well as rainwater collection, and has an active leachate collection system. if these devices are not
successful in keeping water from collecting in the unit and endangering the structural integrity of the unit
at any time, the Division may modify this permit to include a freeboard requirement.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within 30 days following receipt of this
permit. This request must be in the form of a written petition, conforming to Chapter 150E of North
Carolina General Statutes, and filed with the Office of Administrative Hearings, 6714 Mail Service
Center, Raleigh, NC 27699-6714. Unless such demands are made, this permit shall be final and binding.
If you need any additional information concerning this matter, please contact Ms. Shannon Mohr
Thornburg by telephone at [phone]or via e-mail at [e-mail].
Sincerely,
for Alan W. Klimek, P.E.
