Subject: : NCG030504 onitoring Request
Hi John,
Somehow I left you off of distribution on a follow-up email on Flowserve. The main point here is that the contributing
area from US 70 is tiny compared to the on -site contributing area. While they may be getting a contribution from the
highway, it's hard to see how it would be significant given the relative areas involved. Now I think that I may have
underestimated the highway contributing area a bit, and so perhaps the ratio of site area to highway area is more like
100:1.

BG,
Good ideal 1 like this for Rick's introduction to NPDES Industrial, depending on Bradley's initial plans for Rick, and his
interest.
Three other aspects occurred to me yesterday:
• 1 did not explore yesterday the consideration of how the copper and zinc results would match up against our
current increased benchmarks;
• And our precedent that we approach metals exceedances with caution as to interpretation and implementation
of response actions because the source might be soils.
• As far as off -site run on from the highway, I note that Flowserve has three driveways off of US 70: all three have
curb inlets immediately upgradient of the driveway as per my observation yesterday driving home, and as
evident on Google Maps aerial photo. Those inlets would serve to intercept most of the flow originating on the
highway frontage. Further, the southernmost drive is at a higher elevation than US 70, so there's no contribution
onto Flowserve property from that one. The other two drives might receive some contribution from US 70, but
again only from a limited area of the highway, which we might approximate as the width of the entrance drives
by the width of the southbound lanes (2 drives) x (-40'x-40' each)= 0.07A vs. a -15A site, a 200:1 ratio (but with
100% runoff from that little area. While perhaps the highway might be somewhat more contaminated than
the permitted site, the Alternate Sampling location data does not suggest such a two -orders of
magnitude difference in concentration.)

KP,
You have covered some very good points as usual! I suggested to Bradley that this might be a good process for Rick to
be involved with, particularly if there is a site visit and working through of what the facility has done vs. what more they

should do before we deem their request sufficient to back off monitoring (or come to another conclusion). Just a thought
to help get Rick familiar with (1) the benchmarks, (2) the challenges of metals in particular, (3) the NCG03 permit, and
(4) our guidance to the ROs on implementing the Tiers. We can talk more with Bradley about that if you agree.
You don't happen to be working on that response to comments on NCG20 from J.F. right now, too, do you? ;)

Subject: RE: NCG030504 Monitoring Request
Hi Bradley,
I'm not sure we have the time to invest a lot in resolving/responding to this request. With that caveat, and
acknowledging that how much time we have is an important consideration, here are my comments.
First, you request a waiver of the monthly monitoring, "to allow us to continue tooperate." Please note that
it seems to us to be highly premature to think that your continued operation of the facility is dependent on
whether the waiver from monthly monitoring is granted directly. If we misunderstand your circumstances,
please inform us of those circumstances.
Request denied at this time on the basis of insufficient information provided. Please continue to abide by the
terms of the permit. Additional information would let us provide a quicker response. It may well be that we
will grant the request, but we just don't understand the site well enough from the one -page letter request. The
point of continued monitoring is to help you to identify or eliminate potential sources. You do not indicate that
you considered the possibility of on -site sources.
Please meet with us_ _Brine a site plan. Show us where you are talking about as to sampling points and as to
actual discharge points into Walnut Creek. We do not seek to make you responsible for pollution generated by
others. We are receptive to the argument that it's not your fault. However, it is necessary for us to get to the
point where we understand the site conditions that support that argument.
4. While we note that there is no record of prior problems from previous inspections, still let's do a site walk -
around. Whether the CO, the RO, or us together. Aerial photos show lots of bits and pieces stored or staged
outside. Someone from the agency needs to see the site.
5. We note that your notification of the agency under Tier 3 was dated December 2, 2014. You entered Tier 3
several months earlier, so why was your notification in December? For outfall 001 copper Tier 3 status was
based on a sample date at the end of September 2014, and it might be possible that the December notification
was timely (within 30 days of receipt of the lab results); but for outfall 002 copper Tier 3 status, the sampling
date was in June 2014; for outfall 002 zinc Tier 3 status, the sampling date was in May 2014. What happened?
6. Without assistance from a graphic site plan, we cannot corroborate your interpretation that data from the
three measuring points work together to establish that copper and zinc pollutants attributable to only site
operations would be within benchmarks. Our cursory review suggests that the data is inconclusive, with the

background concentrations sometimes greater than one or both of the two site outfalls, and sometimes less,
and sometimes exactly equal.
7. The list of BMP responses is interesting. When were the several BMPs implemented, and does the data show a
before and after difference based on the time of implementation of the BMPs?
a. What media is installed in the basin inserts in order to filter out metals?
b. Was the street sweeping BMP a one-time measure, or have you established an increase in sweeping
frequency?
c. Removing trash and debris is always good.
d. Have you considered inside storage for some of the many bits a pieces visible in aerial photos of the
site?
8. We note that your business is metal fabrication and assembly of mechanical components (valves, pumps,
fittings?) We assume that zinc and copper are included in your raw materials, perhaps as galvanized materials
or perhaps as brass, bronze or copper alloys. If not, please advise us of that fact. It could be important for us
to understand that.
9. We note an oil and grease result of 95.1 mg/L in outfall 002 from the June 2014 sampling event. The result is
approximately 20 times higher than the next highest result. What happened?
10. Confusing with respect to the expectation that the BMP measures implemented have reduced polluted
discharges, we note that the last sample event in November 2014 reported TSS of 109 mg/L, the highest value
cited in your letter; and 0.7 mg/L zinc, the highest value cited in your letter; and 0.053 mg/L copper, the
second highest value cited in your letter. We do note however, that the off -site contributions of these
pollutants also appeared to be high compared to previous measurements. It's difficult to interpret this data
with confidence.
Summary: Let's meet; let's visit the site; then let's talk about whether continued monthly monitoring really helps us
understand what's going on at this site. As far as I can tell, their argument is in two parts: we've already done some
stuff, and, it's not our fault. Both good points. But, they have not relayed to us in this letter that copper and zinc are
absent from their manufacturing processes. They have not told us that they have investigated the site looking for hot
spot sources. The data set is not readily interpretable as they seek to interpret it, it seems to me. Everything they say
may be the actual fact, but this two -page letter does not seem sufficient for our determination.

response for this site, however, I need your collective help. I appreciate Ken's detailed and thoughtful response, and
after discussing this site with him yesterday, i believe we are on the same page regarding the need for additional ,
information from the client. I think we could respond to the client's request with a call for additional details and a site
meeting to verify/strengthen the supporting data for the action they desire; or perhaps we should just set up the

I have reviewed the BIMS record and checked for our RRO file. It appears that we do not have a site map showing the
outfalls. The last inspection was in 2011, and no particular problems have been identified. Finally, since Ken was
available, I discussed this matter with him to check out my own thoughts and continue my "on-the-job training" in the
stormwater program. Based on the available data and documentation, I offer the following comments:
The impacts associated with off -site runoff appear plausible; however, it would be helpful to have a site map on
file to show the outfalls with respect to one another.
While it is clear that they have instituted BM Ps, it would again be helpful to have a. little more detail about how
they have upgraded their action plan through the BMPs they have identified.
I am inclined to support the requested waiver with a little more documentation from the client as noted
above. The proposed monitoring going forward appears to be appropriate.
if there are any questions, please advise.

In accordance with our Stormwater General Permit No. NCG030000, this letter is to inform you
that after four measurements, we have exceeded our Tier 2 Requirements and are in Tier 3 of
our permit. s C" 4-C,r Gy Clot 40¢2.
We have performed upstrea (Alternate; FL-ALT) and downstream monitoring (SDO-001 &
5D0-002)�to characterize theimpact on our receiving water SDO-001 was chosen as it ��
minimizes the number of 5 f6Il points at our facility and an early first flush sample would not

r�se Services Group) sampling events support we are receiving stormwater from South Saunders
P Street (FL-ALT) that exceeds the benchmarks set forth by NCDENR/DEMLR.
We have also taken Best Management Steps that include sweeping the parking lot, removing
trash & debris, installing'basiri inserts7in our storage, receiving & shipping areas to filter metals.Pd�z
We have also installed dram tags that say "No Dumping - Drains to River". With all of these
BMPs in place, we are seeing Copper and Zinc measurements lower in our discharges than in
the off -site runoff flowing into our outfalls. Copper BMV;s extremely law and_may never be eve n� &)'s
achievable in an urban environment with several off -site sources of Copper contributing to run- � ntpkeo rNI-11;"

I am asking for a waiver from the monthly monitoring to allow us to continue to operate. We will
continue to have our Copper, Lead, Zinc, Oil & Grease, and TSS measured twice per year. I 1
will also continue to send you copies of our reports twice per year.

Subject: NPDES Stormwater Permit Coverage Renewal
Flowserve US Inc -Raleigh
COC Number NCG030504
Wake County
in response to your renewal application for continued coverage under stormwater General Permit NCG030000
the Division of Water Quality (DWQ) is forwarding herewith the reissued General Permit. This permit is
reissued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between the state of North Carolina and the U.S. Environmental Protection Agency, dated October
15, 2007 (or as subsequently amended).
The following information is included with your permit package:
• A new Certificate of Coverage (COC)
• A copy of General Permit NCG030000
• A copy of the Technical Bulletin for the General Permit
• Two copies of the Discharge Monitoring Report (DMR) Form
• Two copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater, and it specifies your obligations for discharge
controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself
with all the changes in the reissued permit. Your facility has six (6) months from the time of receipt of the
permit to update your current SPPP to reflect all new permit requirements.
The first sample period of your permit begins January 1, 2013. Your facility must sample a "measureable
storm event" beginning during the periods beginning January 1 and July 1 of every year (or, if applicable,
report "No Flow," as outlined in Part III, Section E). Also, please note that Tier 3 Actions in Part II of your
permit are triggered by benchmark exceedances on four occasions beginning on the effective date of this
permit and do not count prior exceedances.
The more significant changes in the General Permit since your last COC was issued are noted either in the
Draft Permit Fact Sheet that accompanied the public notice (http://portal.ncdenr.org/web/wq/ws/su/current-
notices), or in the Response to Comments / Summary of Changes and Technical Bulletin documents that are
posted on the Stormwater Permitting Unit's website with the new General Permit. Please visit
http://­portal.ncdenr.org/web/wq/ws/su/npdessw (click on 'General Permits' tab) to review that information
for your specific General Permit carefully.

Some of the changes include:
Part II:
• Section A: The Stormwater Pollution Prevention Plan (SPPP) section, if applicable, has been updated
to the most current language of our permits. Additional conditions for specific industry sectors have
been added to the SPPP requirements in some cases.
• Sections B, C: Failure to perform analytical stormwater monitoring may result in the Division requiring
that the permittee begin a monthly sampling scheme.
• Sections B, C: A lower TSS benchmark of 50 mg/I for HOW, ORW, PNA and Tr Waters applies to these
more sensitive waters.
• Sections B, C. The monitoring parameter Oil & Grease (O&G) has been replaced by the parameter
Total Petroleum Hydrocarbons (TPH) for vehicle maintenance areas, and in some cases, other
analytical monitoring requirements.
• Sections B, C, D: Inability to sample due to adverse weather must be recorded in the SPPP, or in
separate on -site records if your General Permit does not require an SPPP. Adverse weather is defined
in the "Definitions" section of the permit.
• Sections B, C. The term "Representative Storm Event" has been replaced by "Measurable Storm
Event." A measurable storm event is defined in the permit.
• Section D: If the permittee fails to respond effectively to problems identified by qualitative
monitoring, DWQ may require the permittee to perform corrective action.
Please review Parts III and IV to understand the Standard Conditions of your new NPDES General Permit,
including Compliance and Liability, Reporting, Monitoring and Records requirements; Operation and
Maintenance obligations; and Definitions. Please note that all samples analyzed in accordance with the terms
of this permit must be submitted to the Division on Discharge Monitoring Report (DMR) forms available on
the Stormwater Permitting Unit's website above. DMR forms must be delivered to the Division no later than
30 days from the date the facility receives the sampling results from the laboratory. Also note that existing
permittees do not need to submit a renewal request prior to expiration unless directed by the Division.
Your coverage under the General Permit is transferable only through the specific action of DWQ. This permit
does not affect the legal requirements to obtain other permits which may be required by DENR, nor does it
relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law,
rule, standard, ordinance, order, judgment, or decree. if you have any questions regarding this permit
package, please contact the Division's Stormwater Permitting Unit at [phone].
