Hi Damon,
No. You're not required to submit data electronically yet. See Part II, Section E (Special Conditions) Item 1. We inserted
a phrase in the first sentence of this item to let permittees off the hook until we get our e-reporting system up and
running. "Effective December 21, 2016 or when the agency's electronic reporting system is able to accept NPDES
stormwater permit monitoring data,...."
We will notify permittees when the e-reporting system is ready to accept stormwater data.

Byron and Damon,
Attached is your draft sormwater permit and cover letter. The cover letter summarizes the changes made from your
previous permit. Please review and let me know if you have any questions or comments, preferably within 30 days. If
you need longer, that's okay — I certainly can't rush you considering how long it took us to get to this point!
I'm also forwarding the draft permit to our Mooresville Regional Office for their comment. They may be contacting you
to conduct a site inspection.
Lastly, we will need to notice the draft permit in a local newspaper. I'll let you know when that runs.

I just wanted to let you know your draft permit is almost ready for your review. It doesn't look like I'll make my deadline
of getting it to you by the end of the month though. I'm waiting on some guidance from our Chemistry lab about the
method used for testing for Oil and Grease. Other than that, it's ready to go. I'll be in touch again next week.

Mr. Crowther,
First, I must apologize for the extremely long delay in getting your permit renewed. I know that Bradley has informed
you of our backlog. I am happy to report that I am working on your permit renewal.
Since it has been so long, I ask that you provide me with a few things to help expedite the process:
1. Stormwater data collected 2013-present
2. Brief description of changes to the facility since Nov 2012. 1 see in a letter dated July 16, 2010 that you were
planning to add a new 388,000 sf factory building. Those of the kind of changes I'd like to know about.
3. Current contact information — see attached summary. This is what we have on our database. Please let me
know if any of that information needs to be updated.
Thank you very much. And again, I'm sorry it's taken this long. I appreciate your patience!

Sir, it is hard to believe it is 2017.
We submitted our renewal for NCS000021 Permit back in November of 2012.
We contacted you via email in November 2013 and where informed we were in the backlog.
We again called in 2014 and 2015 with no change in status.
We continue to execute our permit in its current form as directed in a letter dated November 19-, 2012 from you.
Do you have a status?

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000021
Charlotte Turbine Generator Service Center
Mecklenburg County
Dear Mr. Crowther:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please
review the draft carefully to ensure thorough understanding of the conditions and
requirements it contains.
The draft permit contains the following significant changes from the facility's current permit:
1. You are required to collect analytical and qualitative monitoring samples during
"measurable storm events" as defined in Part II, Section B. This term is different
from the "representative storm event" in earlier permits.
2. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part 1I,
Section A.
3. Changes have been made to three monitoring parameters, including changes to two
benchmarks. Stormwater benchmarks are not permit limits, but rather guidelines for
implementing the Stormwater Pollution Prevention Plan (SPPP). A benchmark
exceedance is not a permit violation; however, the permittee must respond to
exceedances as directed in the Tiers.
Non -polar Oil & Grease [EPA Method 1664 (SGT-HEM)j replaces Oil &
Grease to better represent potential discharges at a facility storing only
petroleum -based fuel oils (as opposed to non -petroleum -based fuel oils). The
benchmark for Non -polar Oil & Grease using this method is 15 mg/L.
• Monitoring for Naphthalene has been added to your permit to better monitor
for heavier fuel oils such as No. 2 fuel oil and diesel that tend to be
underreported using EPA Method 1664 for Oil & Grease. The benchmark for
naphthalene is'l mg/L.

1612 Mail Service Center 1 512 North Salisbury Street I Raleigh, NC 27699-1612
919 707 9200 T

• Vehicle maintenance (Tables 5,6) monitoring parameters have been revised
as follows: '
o Non -Polar Oil & Grease [EPA Method 1664 (SGT-HEM)] replaces
Oil & Grease/TPH. This requirement appears in all individual
stormwater permits; however, it only applies to facilities that
perform onsite vehicle maintenance activities. If the facility begins
vehicle maintenance during the permit cycle, the requirements shall
apply.
pH monitoring is no longer required for discharges only associated
with vehicle maintenance activities.
4. A new section on Special Conditions has been added in Part II, Section E to comply
with federal regulations requiring electronic submittal of discharge monitoring
reports. This section of the permit will become effective December 21, 2016.
S. Civil and administrative penalty amounts have been updated to reflect current
federal law in Part III, Section A, 2(b) and (g).
6. Representative Outfall Status will continue to be granted such that Stormwater
Discharge OutfaIl (SDO) 008 can be represented by SDO 007. Analytical monitoring
shall continue at all other SDOs. Any actions you initiate in response to benchmark
exceedances as directed in the tiered response provisions of your permit must address
all drainage areas represented by SDOs 007, where appropriate. Qualitative
monitoring shall continue to be required at all SDOs, including SDO 008.
Please review the draft permit and submit any continents to me no later than 30 days
following your receipt of the draft. Comments may be emailed to me at
julie.ventatoro(a� cn denr.gov or mailed to my attention at NCDEQ, Land Quality Section,

3. Receiving Waters: Lake Wylie is impaired due to nutrients (high chlorophyll a; algal
blooms). There is an approved TMDL for Lake Wylie. This is the reason Total Nitrogen
monitoring was added during the previous permit cycle.
4. Threatened and Endangered Species: None at discharge to Lake Wylie. Further
downstream in Lake Wylie there are element occurrences of a fish and bird that have
Special Concern State protection status, but no Federal protection status.
5. Analytical and for qualitative monitoring during this past permit cycle:
0 o_data provided for 2014.
o Two consegitiveedancesOutOutfall 006' 015.. Monthly monitoring
should have been triggered. but I didn't see evidence of this occurrinE
6. Ration&,_ r_moni oring_parameters: Their lab has been using EPA Method 1664B to
analyze for Oil and Grease. This is an approved method for motor oils, but it is not
appropriate for fuel oils that are heavy oils or volatilize at certain temperatures, such as
#2 Fuel Oil. There are large amounts of #2 Fuel Oil as well as other heavy oils stored on
site, so EPA Method 1664B is not appropriate. I am proposing to add monitoring for
naphthalene which should be better indicators of the presence of #2 Fuel Oil as well as
diesel in stormwater samples.
7. ECrmit..Facility, and_Qwner CoB acts updatgs:
® Confirmed contact information with permittee and updated BIMS if necessary.
® Obtained e-mail addresses for each contact and updated BIMS.
8. Annual Fees:
® Confirmed in BIMS that permittee does not owe fees.
Recommendations:
Based on the documents reviewed, the application information submitted on Oct 17, 2012
and Apr 11, 2017 is sufficient to issue an Individual NPDES Stormwater Permit.
Central Office recommends reissuance of this permit with the modifications described
above. The proposed draft permit reflects the most recent individual stormwater permit
template and boiler plate language, incorporating revisions that are similar to the
industrial general permits issued during 2012-13.

Subject: Siemens NCS000021 Draft Permit- Charlotte Turbine Generator Service Center
Based on my site inspection and review of stormwater records I have the following comments regarding the permit
renewal.
1) pH- most outfalls are on the high side. I have asked them the to further investigate sources contributing to high pH
(cutting oil mist, HVAC condensate, roof, etc.) and I will be providing follow up technical assistance this year.
2) Nitrogen- all outfalls have indicated low Nitrogen, I would consider removing Nitrogen unless discharging to a Lake
Wylie cove would prevent it.
3) Naphthalene- I agree with adding the parameter.
4) Outfall 9 was removed / built over during the inspection. Outfalls 12 and 13 are new and based on monitoring data,
13 could be representative of 12 if they want to reduce the number of outfall locations in the future.
have left a message with Julie Ventaloro to discuss.

NCG000021 Siemen's Energy
JV notes5/3/2017
The issue: Facility that manufactures turbines and generators for power generation. The facility stores
large amounts of No. 2 Fuel Oil on their site (and diesel). They are currently testing for Oil and Grease
(EPA 1664B); however it's our understanding that this method is not suitable for #2 fuel oil because #2
fuel oil volatilizes at temps below 85 deg C.
NCG510000 wastewater permit has effluent limits for oil and grease, naphthalene, and total recoverable
phenolics. This is for facilities with treated ww from a diesel fuel, aviation fuel, kerosene, or fuel oil
contaminated groundwater remediation system.
For NCS000021 which stores large amounts of diesel fuel as well as No. 2 home heating fuel oil, I
decided not necessary to monitor for phenols as they are usually found in lower concentrations in
refined petroleum such as diesel fuel as compared to crude oils. Naphthalene seems to be appropriate,
is approved by EPA, and we have an established benchmark for it.
Looked into using TPH Diesel Range Organics (EPA SW-846 Method 8015C) instead of naphthalene. That
would return a "lump sum" value of everything that falls within the carbon range of the fuel type. This
method is approved for solid waste, but not specifically for water, although I think it could be used since
there is no other established approved method like this. But I decided there didn't seem to be an
advantage to using TPH DRO over the more -specific naphthalene — they would both be good indicators
of diesel/home heating fuel contamination. Napthalene has the advantage of having been vetted for
water already and is used by ww folks for remediation.
TI q - 733- 390$
Synthesized input from EPA (Jeffrey Wilmonth and Lem Walker), as well as Chris Johnson with DEQ C 2Zy
Chemistry Lab. In the future, if we decide to pursue TPH DRO, here is how to reference it:
TPH-Diesel Range Organics (EPA SW-846 Method 8015C). The lab must use appropriate technique for
surface water.
The lab will have the choice to use solvent extraction or headspace as the analysis technique. I
contacted ENCO lab in Cary, NC — they said they would use solvent extraction in methylene chloride plus
GC at a cost of about $45 per sample. Their PQL (or reporting level) is 0.1 mg/L; their MDL is 0.06 mg/L.
So they can report down to 0.06 but calibrate down to 0.1. [Is that backwards?]
Chris Johnson says he has rarely seen a surface water sample that exceeded the Chem Lab's PQL of 500
ppb (.5 mg/L).
Also considered Total PAH's, but that test is very broad and costly at $300/sample. BTEX also
considered but more appropriate for gasolines/light fuels.

Typically this is analyzed by a hydrocarbon method depending on the carbon range of the fuel type. From SW-846`
Method 8015 17
G11,
This method may also be applicable to the analysis of petroleum hydrocarbons, including
gasoline range organics (GROs) and diesel range organics (DROs). GROs correspond to the range
of alkanes from C6 to C10 and covering a boiling point range of approximately 60C - 170C.
DROs correspond to the range of alkanes from C10 to C28 and covering a boiling point range of approximately
170C - 430C
These methods are not regulated under RCRA nor are they in CFR 136 but I believe the States have the authority to
apply proven, established methods for permitting where no other applicable method is available. I can verify this if
needed.
I believe North Carolina has a version of the MAEPH (extractable petroleum hydrocarbons) and MAVPH (volatile
petroleum hydrocarbons) that may also be useful for this type of analyte?
The main difference between Method 8015 and the EPH/VPH methods is that the EPH/VPH methods provide more
detail in the results. Method 8015 gives a one "lump sum" value of everything that falls within the Carbon range.
VPH/EPH actually breaks down the constituents in the carbon range by aliphatic (chain) and aromatic (ringed)
hydrocarbons, which, can give a better idea of toxicity since one is generally more harmful than the other.
Often EPA method 8260 (for BTEX) and 8270 (f'or PAHs) are requested alongside 8015 to provide a more detailed picture
of contamination (individual analyte identification). For wastewater, these would equate to Methods 602/624/1624 for
BTEX or 610/625/1625 for PAH.
Please let me know if you wish to discuss further.
Thanks!

Hi Jeff,
Our NPDES Stormwater Permitting section has a facility with a permit up for renewal and this facility stores large
amounts of No. 2 fuel oil on site. They are asking what analytical method(s) of analysis are generally specified for this
type permit?

Subject: RE: No. 2 Fuel oil analysis
Dana,
Yes, you are correct that the oil and grease may not represent the more volatile constituents of the Fuel oil.
Diesel fuel should contain more of the PAH analytes (610/625/1625) than the BTEX analytes (602/624/1624 )due to
boiling point/volatility characteristics. If this was more a gasoline type of fuel the opposite would apply. However, as you
mentioned, the percentages of these analytes that make up the blend may not be known or able to be related
quantitatively. In other words, how much PAH analyte concentration would relate to overall No.2 Fuel Oil presence?
That is why I would recommend method 8015 or VPH/EPH methods mentioned earlier, if an exception can be allowed
for Stormwater.

If you could get a sample of the product and have it analyzed by 1664E and the PAH/BTEX 136 methods it would give
you a better idea of what to expect and permit for.
I am copying Lem to get more guidance in regards to flexibility within the Stormwater rules that may allow methods
outside 40 CFR 136, especially if it can be demonstrated that approved methods do not address the contaminant of
concern with enough quantitative accuracy.
Thanks All!

Thank you, as always, for an unbelievably prompt and thorough response!
1 believe the stormwater rules may require 40 CFR Part 136 methods.
So, I suppose they could use 1664 B as Lem suggests, but with an understanding that it might be a low estimation since
material that volatilizes below 85 degrees C may be partially lost during solvent removal?
What would you say would be the primary targets needed to characterize No. 2 fuel oil from Methods 602/624/1624
and/or 610/625/1625 without reporting non -targeted compounds? I don't know the percentages of say the alkanes that
make up diesel fuel.
Thanks so much for your help.

Hi Dana,

Bethany suggested I reach out to you with a question that's come up with a facility that manufactures turbines and
generators for power generation.
This facility has an NPDES stormwater permit which is up for renewal. Among other types of oil, they store large
amounts of No. 2 Fuel Oil on their site. Their current permit requires them to test for "Oil and Grease" at their
outfalls. The lab they're using uses EPA 1664B. It's our understanding (from earlier guidance you've given us) is that
Method 1664B is not suitable for #2 fuel oil because it volatilizes at temps below 85 deg C.
Is there another EPA approved method that would better capture this type of fuel oil? If not, do you know of a different
parameter we could use to better monitor for #2 fuel oil in stormwater? Or maybe monitor for 0&G (Method 1664B)
AND naphthalene and/or total phenols? Noticed that wastewater folks require testing for naphthalene and total
phenols for groundwater remediation.
Thanks for your help!

please continue to comply with all conditions and monitoring requirements in your expired NPDES
stormwater permit.
The application and supplement must be completed and returned to DWQ by November 1. 2Q12. Failure to
request renewal within this time period will result in delay of your permit renewal and may result in a civil
assessment. Discharge of stormwater from your facility without coverage under a valid stormwater NPDES
permit would constitute a violation of NCGS 143-215.1 and could result in assessments of civil penalties of up
to $25,000 per day.

Attachments: Dana Satte►white3.vcf; image001.jpg
Actually, SM 5520 B and EPA 1664 A are very similar methods, using the n-hexane extraction solvent. The 1664 method
is simply more prescriptive in terms of required quality control and goes on to address the SGT-HEM within that method.
SM 5520 B does not address the silica gel treatment for hydrocarbon determination, but SM 5520 F does; however, this
method (SM 5520 F) does not appear in 40 CFR Part 136.
So all the labs are pretty much in the same boat as far as gearing up for reporting SGT-HEM (labs citing SM 5520 B could
easily switch to 1664A with just a little extra QC). The extra step only involves contact between the extracted solvent
and silica gel and filtration then a final gravimetric determination. As I mentioned before, to date there has not been any
market for the SGT-HEM method so that may be why they are not offering it. It wouldn't take much to get it up and
running, so I think the labs would just need to understand that the demand will be worth the effort.

Subject: RE: TPH analysis by 1664
Ah, I understand now. Great question about certification...
Actually stormwater differs from wastewater (even though we're both under NPDES). The methods and procedures still
must be acceptable as per the NPDES permit requirements —but technically, NC certification is *not required* for
analyzing stormwater-only discharges.
We worked this out when we started requiring pH more broadly in our SW permits, and we had problems with people
failing to measure it in the field because they claimed they weren't 'certified' to do it — they just wanted to send a
sample to their 'certified' lab like they always did (which might be in Minnesota for all we know and = pH meas. of little

%ft
use) We investigated the applicability of the NC rules and found that indeed, while permittees still had to analyze it
correctly (i.e., same as any certified lab or field entity would, proper probe and calibration, etc.), but they didn't have to
do the paperwork or pay the fee to 'maintain certification'.
If we follow the same logic, a lab 'not certified' to employ 1664A for TPH, but performing the test per the method, would
still satisfy our permit requirements.
But, that still leaves us with the labs that are certified for Standard Method 5520B, but not 1664A... could they still easily
do 1664A, or likely not because they don't have the skill and/or materials needed? (in other words, can the permittee
say, "Oh no, don't worry — you don't need certification for it since it's just a stormwater sample. lust run it anyway."?)
What's the proportion of labs in NC that are not certified for 1664A (roughly)?
Thanks — this is all incredibly helpful!

The problem we run into is our Certification Rules (15A NCAC 2H .0800) only lists "Oil and Grease" as a certifiable
parameter and since EPA proclaimed that HEM was an approved alternative to that codified parameter, we are able to
certify for Oil and Grease by 1664A HEM. The SGT-HEM would not be deemed equivalent to Oil and Grease, but rather
TPH, if you accept the limitations of this determination, and our Certification Rules only list TPH California Method —
DRO and GRO as a certifiable parameter (this specificity was driven primarily by the UST program testing requirements
when our Rules were written). So we do not really have the authority to certify for TPH by 1664A.
Now, that only matters if your Rules require a certified laboratory or methodology consistent with 40 CFR Part 136, etc. I
simply pointed those things out in case that was where some of the confusion/reluctance from the labs was coming
from.
Yes, we have labs certified for only the Standard Methods methods (55208) and not 1664A.
If you feel SGT-HEM by 1664A is appropriate for the intended use, you can go with that. There does not appear to have
been any driver previously that would cause commercial laboratories in this state to develop that method and so this
may also be part of the reason they are not offering that analytical testing right now. It may help them to know how
much work this new permit requirement will presumably generate so that they can evaluate whether it would be
feasible economically for them to offer that service.
Is a certified laboratory required for this testing?

Subject: RE: TPH analysis by 1664
So Dana, if a lab is certified to run EPA 1664A HEM, they are not necessarily certified to run HEM-SGT? Or are they, but
.some labs are confused because they think they cannot?. Are some labs only certified to run SM5520 B and 5M5520 B-
01, rather than EPA 1664A? (If so, is it just some labs, or the majority?)
We generally are trying to identify petroleum compounds (possibly fuels, but I'd say more often motor oil) that may
contaminate stormwater runoff from vehicle maintenance areas. We do not need an analysis that identifies the
constituents, so non-specific in that sense is fine. It seems to us TPH is a more targeted monitoring parameter for this
purpose than 0&G. Even if the NPM quantified by the method may not capture everything, it still sounds appropriate
for detecting petroleum -based compounds we would anticipate to be present in those areas.
Thanks so much for your help with our questionsl

Subject: RE: TPH analysis by 1664
Hi Connie,

believe this is one of those "come to terms" issues. I think there is some confusion over what exactly EPA 1664A will
give you (i.e., HEM and SGT-HEM). It's a matter of interpretation whether it will give you a TPH value. The two
constituents derived by 1664A are method -defined anaiytes and are defined as follows:
HEM or n-hexane extractable material - Material that is extracted from a sample and determined by this method
(oil and grease). This material includes relatively non-volatile hydrocarbons, vegetable oils, animal fats, waxes,
soaps, greases, and related matter.
SGT-HEM or silica gel treated n-hexane extractable material - Components of n-Hexane extractable material (HEM)
that are not adsorbed by silica gel; i.e., non -polar material (NPM).
You will often see HEM used interchangeably with Oil and Grease. Although some believe the term 'Oil and Grease' is
somewhat of a misnomer since materials other oils and greases are extractable with n-hexane.
Since petroleum hydrocarbons are non -polar materials, sometimes the assumption is made that these terms are
equivalent, however, some regulatory entities believe that TPH or total petroleum hydrocarbons may or may not be
equivalent to NPM. EPA 1664A is not applicable to measurement of materials that volatilize at temps below 85 degrees
C. Petroleum fuels from gasoline thru #2 fuel oil may be partially lost in the solvent removal step and since some crude
oils and heavy fuel oils contain a significant amounts of materials that are not soluble in n-hexane, recoveries may be
low. Motor oils; however, are consistently detected using 1664A.
So, it all depends on what exactly you are looking for and whether the methodology must be 40 CFR Part 136 compliant
or not.
If the methodology must meet 40 CFR Part 136 requirements, the only approved methods for total recoverable Oil and
Grease are EPA 1664A and SM5520 B and SM5520 B-01(hexane solvent extraction only).
These are pretty non-specific methods, whereas, the GC methods will give more detailed information about the
constituent contaminants. Is petroleum contamination the primary concern? If so, even the IR TPH method (418.1 which
was referenced when developing 1664A) is not specific to hydrocarbons. Note: EPA 418.1 utilizes Freon and is not an
approved method per 40 CFR Part 136. More recently, an ASTM method was developed to replace 418.1 that uses a
different extraction solvent, but it is not approved in 40 CFR Part 136 either.
In addition, we have only offered certification for HEM by 1664A and SM 5520 B to date since this was the replacement
method for Oil and Grease which is the codified parameter in 40 CFR Part 136. We generally do not get requests for SGT-
HEM. SW-846 8015C is generally the certified method for TPH. Some of the answers from the labs might be attributed to
their certification status?
As far as cost-effectiveness goes, 85% purity n-hexane (the minimum purity required for 1664A) is not accessible and
labs must purchase a higher purity n-hexane which I have heard runs close to $200 per 4 liters.
Hope this doesn't confuse the issue more.

Ladies,
See below for a comment we've gotten from the NC Aggregates Association on the TPH analysis via EPA's 1664 (SGT-
HEM), which we have specified in our draft permit for mining activities to ensure the most cost-effective method can be
used (in lieu of the more fancy ways of getting at TPH with gas chromatography.) They are claiming that some labs will
not perform the test. Do you buy it? Seems strange that they could run an old fashioned 0&G with 1664 (which I
assume they have to use for that anyway?) but not the extra step to get TPH?
Would appreciate any input!

Subject: NCG02 Draft Permit
Bethany,
Thanks for emailing the draft permit to NCAA earlier this week, our members appreciated it. I can see from my
review that you tried to incorporate concerns / issues the industry raised - we appreciate your help.
I do have a few comments and requests after several members also reviewed the final draft.
Can DWQ forward the edited version of the final draft that shows all the changes. It would help them
see the changes / edits more quickly. So, they do not have to read the entire permit.
The change from O/G testing to TPH testing - There needs to be additional research from the DWQ lab
about the method of testing for TPH. MMA contacted the three labs that provide testing for their NC
quarries, and discovered the following concerning the EPA Test Method 1664 (SGT-HEM) for TPH -
one can provide the test, and two that can not. One of the labs that can not provide the test handles 90%
of MMA samples in eastern NC. For labs that can not provide this test, the sample would have to be
shipped to another lab in order to complete the required testing. (Most of our members like to deliver
the sample in person and eliminate the need to mail a sample.) Can DWQ contact several labs to get a
better understanding of why they, and possibly many other labs, can not perform this test. The response
from one lab - the test requested is for UST. I can contact NCAA members and get several labs and
contact names if needed.
Turbidity benchmark values have been removed from the Tables and N/A is placed in that column.
Turbidity is now addressed below the tables. Members want a clarification about this - do we have to
test? Just let us know what you mean, a little confusing.
On -site vehicle maintenance areas table - again clarification about what you want for "new motor oil
usage" semi annual samples - ???? Do you want a sample or just the estimated
number of gallons used per month? Again clarification.
Table 9 (Part III page 14 of 15) - change the heading from Semi-annual to Quarterly.
Thanks again for taking the time to conduct several stakeholder meetings.

Dear Mr. Carpenter:
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:
+ All analytical monitoring has changed from quarterly in the 4th year to semi-annual. This
change is based.on the Division's revised strategy for stormwater monitoring in renewal permits
and makes stormwater discharge sampling frequency consistent with qualitative monitoring.
Please note that analytical monitoring must still be performed during a representative storm
event.
• Monitoring for Total Nitrogen has been added to the analytical monitoring based on Lake Wylie
being impaired for nutrients.
• Monitoring for pH has been added to the analytical monitoring based on the Division's revised
strategy for stormwater monitoring.
+ The Division has incorporated benchmark values into the permit. These benchmarks are not
permit limits but should be used as guidelines for your facility's Stormwater Pollution Prevention
Plan (SPPP). If any measurements exceed benchmark values, your facility should evaluate the
effectiveness of its Best Management Practices (BMPs), review and/or update its SPPP, and
document any efforts to address stormwater contamination (see Part II, Sections B and D).
• Total Flow monitoring has been removed. The permit still requires Total Rainfall amount be
recorded for each sampling event. This change is also based on the Division's revised strategy
for stormwater monitoring in renewal permits. Please note that the Stormwater Pollution
Prevention PIan (SPPP) site map must include drainage area for each outfall in acres and the
percentage of each drainage area that is impervious (see Part II, Sec. A).
You reported that Outfall 007 is representative of Outfall 008. After review of your letter and site plan,
Siemens may conduct the required analytical sampling on Outfall 007 as representative for Outfall 008 and
may discontinue analytical monitoring of Outfall 008. Please note that OutfaIl 008 must still be included
in the semi-annual qualitative monitoring events.
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

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten 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
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.`.

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000021
Charlotte Turbine Generator Plant
Mecklenburg County
Enclosed with this letter is a copy of the draft stormwater permit for your facility. PIease review the draft
very carefuIIy 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:
• All analytical monitoring has changed from quarterly in the 4fh year to semi-annual. This
change is based on the Division's revised strategy for stormwater monitoring in renewal permits
and makes stormwater discharge sampling frequency consistent with qualitative monitoring.
Please note that analytical monitoring must still be performed during a representative storm
event.
• Monitoring for Total Nitrogen has been added to the analytical monitoring based on Lake Wylie
being impaired for nutrients.
+ Monitoring for pH has been added to the analytical monitoring based on the Division's revised
strategy for stormwater monitoring.
• The Division has incorporated benchmark values into the permit. These benchmarks are not
permit limits but should be used as guidelines for your facility's Stormwater Pollution Prevention
Plan (SPPP). If any measurements exceed benchmark values, your facility should evaluate the
effectiveness of its Best Management Practices (BMPs), review and/or update its SPPP, and
document any efforts to address stormwater contamination (see Part I1, Sections B and D).
• Total Flow monitoring has been removed. The permit still requires Total Rainfall amount be
recorded for each sampling event. This change is also based on the Division's revised strategy
for stormwater monitoring in renewal permits. Please note that the Stormwater Pollution
Prevention Plan (SPPP) site map must include drainage area for each outfall in acres and the
percentage of each drainage area that is impervious (see Part 11, Sec. A).
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] x 360 or

water priority chemicals; and storage in any amount of hazardous substances 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 directly to stormwater 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 area shall be at a minimum visually observed for color, foam,
outfall staining, visible sheens and dry weather flow, prior to release of the

inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, an oil SPCC plan 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 inc rporated by reference into the
SPRP. /\ 7
4. Preventative Maintenance and Good Housekegping%Pro preventative
maintenance program shall be developed. The'program s ai document schedules of
inspections and maintenance activities of stormywater,control systems, plant equipment
and systems. Inspection of material handlingeas and'regular cleaning schedules of

(or team) responsible f '`impleting the training shall be identified.
b. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsibl'e,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 that has a significant effect on the
potential for the discharge of pollutants to surface waters. 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
re -certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges.
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 III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten 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
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.

Revised Permit Recommendations: Analytical Monitoring:
1. pH and total nitrogen has been added to the analytical monitoring requirements.
2. Due to a potential lag time between the expiration of this permit and its renewal, I have specified in the permit
that the permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables
1, 4, and 5. This approach is recommended because there has been a significant lag time since the expiration of
the previous cycle. This will provide testing if there is a lag in future timeframes. "Measurement Frequency: All
monitoring will be performed two times per year for each year until either another permit is issued for this
facility or until this permit is revoked or rescinded. If at the end of this permitting cycle, the permittee has
submitted the appropriate paperwork for a renewal permit before the submittal deadline, the permittee will be
considered for a renewal application. The applicant must continue semi-annual monitoring until the renewed
permit is issued. See Table 2 for schedule of monitoring periods through the end of this permitting cycle."
3. Benchmarks have been added to this draft permit.
4. All analytical monitoring has been set to semi-annually.
5. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
6. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in this permit.
Other Proposed Changes to the Previous Permit:
1. Part II Section A has been revised. It now specifies all of the items to include on the site map.
2. Vehicle maintenance has been revised to semi-annually in order to coincide with analytical and qualitative
monitoring.

Dear Mr. Carpenter:
Draft NPDES Stormwater Permit
Permit No. NCS000021
Charlotte Turbine Generator Plant
Mecklenburg County
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 foIlowing significant changes from this facility's current permit:
• All analytical monitoring has changed from quarterly in the 4th year to semi-annual. This
change is based on the Division's revised strategy for stormwater monitoring in renewal permits
and makes stormwater discharge sampling frequency consistent with qualitative monitoring.
Please note that analytical monitoring must still be performed during a representative storm
event.
• Monitoring for Total Nitrogen has been added to the analytical monitoring based on Lake Wylie
being impaired for nutrients.
• Monitoring for pH has been added to the analytical monitoring based on the Division's revised
strategy for stormwater monitoring.
• The Division has incorporated benchmark values into the permit. These benchmarks are not
permit limits but should be used as guidelines for your facility's Stormwater Pollution Prevention
Plan (SPPP). If any measurements exceed benchmark values, your facility should evaluate the
effectiveness of its Best Management Practices (BMPs), review and/or update its SPPP, and
document any efforts to address stormwater contamination (see Part 11, Sections B and D).
• Total Flow monitoring has been removed. The permit still requires Total Rainfall amount be
recorded for each sampling event. This change is also based on the Division's revised strategy
for stormwater monitoring in renewal permits. Please note that the Stormwater Pollution
Prevention Plan (SPPP) site map must include drainage area for each outfall in acres and the
percentage of each drainage area that is impervious (see Part. II, Sec. A).
Please submit any comments to me no Iater 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] x 360 or
[e-mail].

As explained by Mr. Moss, Siemens Westinghouse had unintentionally missed the first two
quarters of the fourth year permit term monitoring schedule, and requested guidance on what
procedures Siemens Westinghouse should follow to correct this deficiency.
It is our understanding as a result of this conversation, Siemens Westinghouse will continue to
sample the remaining representative storm event as outlined in Section B of the monitoring
schedule, and in addition, will sample representative storm events of the first two quarters of the
fifth year of the permit term.
Siemens Westinghouse requests conformation from the Division of Water Quality, in writing, that .
the revised monitoring schedule outlined above is acceptable.
Please contact meat [phone] if you have any questions. Thank you for your assistance in

Central Office Review Summary:
1. Owner's Other Permits: (If applicable)
0
2, General Observations: Manufacturing takes place inside buildings. Various dust collectors in facility. Bulk oil
storage activities — fuel oil tanks, lubrication oil tanks, diesel fuel tanks, 55-gal hazardous waste drum storage, waste
oil storage tanks, 55-g4l hazardous materials drum storage buildings, 55-gal miscellaneous oil drum storage, waste
oil/water storage tank, kerosene.
3. Impairment: This section of Lake Wylie is impaired by eutrophication; due to chlorophyll a standard violations
and algal blooms. There is an approved (1991) Lake Wylie TMDL. Recommend adding monitoringfor total
nitrogen due to this impairment.
4. Threatened and Endangered: None at discharge to Lake Wylie. Further downstream in Lake Wylie there are
element occurrences of a fish and bird that have Special Concern (SC) State protection status, but no Federal
protection status. No recommendation based on this information related to T&E.
5. Location: 5101 Westinghouse Blvd., Charlotte, NC 28273
6. Industrial Changes Since Previous Permit: Some new buildings/facilities were added since the previous permit.
o 2000- Abrasive Blast Facility -- abrasive cleaning of service repair equipment for the nuclear valve
industry; aluminum oxide blast medid is a potential stormwater contaminant
0 2000 — Global Vacuum Pressure Impregnation (GVPI) Facility — vacuum pressure impregnation of
electric generators for the power generation industry
o 2001 — Abrasive Blast Facility (Indoors) — cleaning and de -contamination of nuclear rotors and
associated equipment for the power generation industry
o 2001 — Heat Treat & Valve Components Facility — heat treat/manufacture component parts for the
nuclear valve industry
o 2002 — Modification to Training Building for a Research and Development Insulation Test Laboratory —
research and development for electric generator coil insulation
7. Analytical Monitoring Notes: At or below benchmarks except for one event at one outfall (007). Permittee
missed the first 2 quarters of monitoring as written in the permit, so they notified us in writing about this and that
they would just monitor the first 2 quarters of the 5"' year of the permit.
8. Qualitative Monitoring Notes: Minor to moderate color and clarity issues at outfall 004 recorded.

Revised Permit Recommendations: Analytical Monitoring:
1. pH and total nitrogen has been added to the analytical monitoring requirements.
2. Due to a potential lag time between the expiration of this permit and its renewal, I have specified in the permit
that the permittee is responsible for all monitoring until the renewal permit is issued. See Footnote I of Tables
1, 4, and 5. This approach is recommended because there has been a significant lag time since the expiration of
the previous cycle. This will provide testing if there is a lag in future timeframes. "Measurement Frequency: All
monitoring will be performed two times per year for each year until either another permit is issued for this
facility or until this permit is revoked or rescinded. If at the end of this permitting cycle, the permittee has
submitted the appropriate paperwork for a renewal permit before the submittal deadline, the permittee will be
considered for a renewal application. The applicant must continue semi-annual monitoring until the renewed
permit is issued. See Table 2 for schedule of monitoring periods through the end of this permitting cycle."
3. Benchmarks have been added to this draft permit.
4. All analytical monitoring has been set to semi-annually.
5. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
6. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in this permit.
Other Proposed Changes to the Previous Permit:
1. Part II Section A has been revised. It now specifies all of the items to include on the site map.
2. Vehicle maintenance has been revised to semi-annually in order to coincide with analytical and qualitative
monitoring.

Dear Mr. Mills
Siemens Westinghouse Power Corporation (Siemens Westinghouse) hereby requests renewal of its
Stormwater Permit, No. NCS000021, for the Charlotte Turbine Generator Plant to discharge
stormwater to the receiving waters designated as Lake Wylie in the Catawba River Basin.
Enclosed is the completed permit application and supplemental information as required by the
Division of Water Quality, North Carolina Department of Environment and Natural resources.
Please note a revision to the 4"' year monitoring schedule was required. Siemens Westinghouse
unintentionally missed the first two (2) quarters of the scheduled 4`l' year sampling schedule as
outlined in Table 2, Part A Page4 of 5. As a result, notification was sent to your attention dated
June 13, 2003, requesting conformation on the revised sampling schedule. A copy of the letter is
attached for your review.
If you have any questions concerning the data furnished, please contact me at [phone]
Sincerely,

Dear Mr. Mills:
At the request of Siemens Westinghouse, Mr. Daniel P. Moss of S&ME Inc. contacted your office
on May 14, 2003 concerning the Sampling Monitoring Schedule for the Siemens Westinghouse
Charlotte Turbine Generator Plant.
As explained by Mr. Moss, Siemens Westinghouse had unintentionally missed the first two
quarters of the fourth year permit term monitoring schedule, and requested guidance on what
procedures Siemens Westinghouse should follow to correct this deficiency.
It is our understanding as a result of this conversation, Siemens Westinghouse will continue to
sample the remaining representative storm event as outlined in Section B of the monitoring
schedule, and in addition, will sample representative storm events of the first two quarters of the
fifth year of the permit term.
Siemens Westinghouse requests conformation from the Division of Water Quality, in writing, that
the revised monitoring schedule outlined above is acceptable.
Please contact meat [phone] if you have any questions. Thank you for your assistance in
this matter.
Sincerely,
SI ENS WESTINGHOUSE OWER CORPORATION

Dear Mr. Mills
Siemens Westinghouse Power Corporation (Siemens Westinghouse) hereby requests renewal of its
Stormwater Permit, No. NCS000021, for the Charlotte Turbine Generator Plant to discharge
stormwater to the receiving waters designated as Lake Wylie in the Catawba River Basin.
Enclosed is the completed permit application and supplemental information as required by the
Division of Water Quality, North Carolina Department of Environment and Natural resources.
Please note a revision to the 4"' year monitoring schedule was required. Siemens Westinghouse
unintentionally missed the first two (2) quarters of the scheduled 4"' year sampling schedule as
outlined in Table 2, Part 11, Page4 of 5. As a result, notification was sent to your attention dated
June 13, 2003, requesting conformation on the revised sampling schedule. A copy of the letter is
attached for your review.
If you have any questions concerning the data furnished, please contact me at [phone]

Dear Mr. Mills:
At the request of Siemens Westinghouse, Mr. Daniel P. Moss of S&ME Inc. contacted your office
on May 14, 2003 concerning the Sampling Monitoring Schedule for the Siemens Westinghouse
Charlotte Turbine Generator Plant.
As explained by Mr. Moss, Siemens Westinghouse had unintentionally missed the first two
quarters of the fourth year permit term monitoring schedule, and requested guidance on what
procedures Siemens Westinghouse should follow to correct this deficiency.
It is our understanding as a result of this conversation, Siemens Westinghouse will continue to
sample the remaining representative storm event as outlined in Section B of the monitoring
schedule, and in addition, will sample representative storm events of the first two quarters of the
fifth year of the permit term.
Siemens Westinghouse requests conformation from the Division of Water Quality, in writing, that
the revised monitoring schedule outlined above is acceptable.
Please contact me at [phone] if you have any questions. Thank you for your assistance in
this matter.

Your facility is currently covered for stormwater discharge under NPDES Permit NCS000021. This permit expires
on September 30, 2004. [forth Carolina Administrative Code (15A NCAC 2H.0105(e)) requires that an
application for permit renewal be filed at least 180 days prior to expiration of the current permit. In order to assure
your continued coverage under your permit, you must apply to the Division of Water Quality (DWQ) for renewal
of your permit. To make this renewal process easier, we are informing you in advance that your permit will be
expiring. Enclosed you will find an individual permit renewal application form, supplemental information request,

requested information by April 3, 2004 in order for the permit to be renewed by September 30, 2004.
Failure to request renewal by April 3, 2004 may result in a civil assessment of at least $500.00. Larger penalties
may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility without
