Permit NC0020737
5. Whole Effluent Toxicity shall be measured by the Chronic Toxicity (P/F) test using Ceriodaphnia dubia
at 33%. Testing shall be conducted in January, April, July and October (see Part A. (2.)). Toxicant
sampling shall coincide with toxicity testing.
6. Instream samples shall be collected three times per week during the months of June -September and
once per week during the remaining months of the year.
7. No later than 270 days from the effective date of this permit, begin submitting discharge
monitoring reports electronically using NC DWR's eDMR application system. See Special
Condition A. (5.).
8. The annual average limit becomes effective January 1, 2019. The facility shall use method
1631E.
There shall be .no discharge of floating solids or visible foam in other than trace amounts.
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
[ 15A NCAC 02B .0200 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 33.0 %.
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 II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions. The tests will be performed during the months of
January, April, July, and October. 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
Procedure" (Revised -February 1998) or subsequent versions.
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 II 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, DWR
Form AT-3 (original) is to be sent to the following address:
Attention: NC DENR / DWR / Water Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Branch 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 Water Sciences Branch at the
Page 4 of 8

Permit NC0020737
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 Resources indicate
potential impacts to the receiving stream, this permit may be re -opened and modified to include
alternate monitoring requirements or limits. If the Permittee monitors any pollutant more frequently
then required by this permit, the results of such monitoring shall be included in the calculation &
reporting of the data submitted on the DMR & all AT Forms submitted.
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 month of the initial monitoring.
A. (3.) EFFLUENT POLLUTANT SCAN
[G.S. 143-215.1(B)]
The Permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed below. One
scan must be performed in each of the following years: 2016, 2017, and 2018. Analytical methods shall be
in accordance with 40 CFR Part 136 and shall be sufficiently sensitive to determine whether parameters are
present in concentrations greater than applicable standards and criteria. Samples should be collected with
one quarterly toxicity test each year, and must represent seasonal variation [i.e., do not sample in the same
quarter every year]. Unless otherwise indicated, metals shall be analyzed as "total recoverable."

Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that Municipal
facilities that are subject to the Effluent Pollutant Scan requirements listed above are also subject to
additional toxicity testing requirements specified in Federal Regulation 40 CFR 122.21(j)(5). The US EPA
requires four (4) toxicity tests for a test organism other than the test species currently required in this
permit. The multiple species tests should be conducted either quarterly for a 12-month period prior to
submittal of the permit renewal application, or four tests performed at least annually in the four and one
half year period prior to the application. These tests shall be performed for acute or chronic toxicity,
whichever is specified in this permit. The multiple species toxicity test results shall be filed with the
Aquatic Toxicology Branch at the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the
additional toxicity tests and reporting requirements. Results should also be summarized in Part E
(Toxicity Testing Data) of EPA Municipal Application Form 2A, when submitting the permit renewal
application to the NPDES Permitting Unit.
A. (4.) MERCURY MINIMIZATION PLAN (MMP)
[G.S. 143-215.1(b)]
The permittee shall develop and implement a mercury minimization plan during this permit term. The
MMP shall be developed within 180 days of the NPDES Permit Effective Date, and shall be available for
inspection on -site. A sample MMP was developed through a stakeholder review process and has been
placed on the Division website for guidance (http://portal.ncdenr.org/web/wq/swp/ps/npdes, under
Model Mercury Minimization Plan). The MMP should place emphasis on identification of mercury
contributors and goals for reduction. Results shall be summarized and submitted with the next permit
renewal. Performance of the Mercury Minimization Plan will meet the requirements of the TMDL (Total
Maximum Daily Load) for mercury approved by USEPA on October 12, 2012, unless and until a Waste
Load Allocation specific to this facility is developed and this NPDES permit is amended to require further
actions to address the Waste Load Allocation.
A. (5.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
specify that, if a state does not establish a system to receive such submittals, then permittees must.

reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR),
permittees will be required to submit all discharge monitoring data to the state electronically using
eDMR and will be required to complete the eDMR submission by printing, signing, and submitting
one signed original and a copy of the computer printed eDMR to the following address:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3) or alternative
forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address
above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be submitted
in writing to the Division for written approval at least sixty (60) days prior to the date the facility
would be required under this permit to begin using eDMR. Temporary waivers shall be valid for
twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted electronically
to the Division unless the permittee re -applies for and is granted a new temporary waiver by the
Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr
Regardless of the submission method, the first DMR is due on the last day of the month following the
issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.

BACKGROUND
The Pilot Creek Wastewater Treatment Plant (WWTP) is a 6.0 MGD treatment facility serving
13,500 residents of Kings Mountain. The facility discharges municipal wastewater (domestic
and industrial) and has a full pretreatment program with seven (7) non -categorical Significant
Industrial Users. The Division will continue to implement the pretreatment program in the
coming permit term.
The Town's treatment system consists of: dual screw pumps, a mechanical bar screens,
Parshall flume with recorder, three aeration basins, three secondary clarifiers, chlorine contact
basins, caustic feed system, dechlorination facilities, aerobic digesters, 2 sludge drying beds,
and a belt press.
PERMIT LIMITATIONS

• BOD winter limits in the permit are based on the requirements of the 40 CFR 133.102.
• TSS limits in the permit are based on the requirements of the 40 CFR 133.102.
• Ammonia limits in the permit are based on the water quality model. The Division uses
ammonia criteria that were developed by EPA: 1 mg/L - summer; 1.8 mg/L — winter.
• DO limit in the permit is based on the water quality model.
• TRC limit in the permit is based on the North Carolina water quality standards [15A
NCAC 2B .0200].
• pH limit in the permit is based on the North Carolina water quality standards [15A
NCAC 2B .0200].

• Cyanide limits in the permit are based on the results of the Reasonable Potential
Analysis.
• Thallium limits in the permit are based on the results of the Reasonable Potential
Analysis.
• Arsenic limits in the permit are based on the results of the Reasonable Potential
Analysis.
• Zinc and Copper limits in the permit are based on the results of the Reasonable
Potential Analysis and compliance issues with the Whole Effluent Toxicity Test.
TOXICITY TESTING
Current Requirement: Chronic Ceriodaphnia Quarterly P/F @ 33%
Testing during the months of January, April, July and October.
The City has had problems passing its whole effluent toxicity tests during the last 5 years. A
toxicity reduction evaluation was performed in Jan. 2006 and it was determined that high
levels of zinc was causing the toxicity problems (please see attached).
DWQ requires that the quarterly chronic Ceriodaphnia toxicity tests @ 33% and limits
for Cu and Zn be continued in the renewed permit.
COMPLIANCE SUMMARY
Overall, the facility has experienced numerous compliance issues, please see attached. Most
violations were for limit excursions for pH, Cd, and Zn. The compliance has significantly
improved in 2013 and 2014, there were no limit violations during these years.
INSTREAM MONITORING
Upstream site: Above effluent discharge
Downstream site: NCSR 1103
A review of temperature, DO, pH and conductivity data showed that most of the time water
quality standards were met for temperature and DO. Over the past 3 years there have been
several instances of low pH values both upstream and downstream of the Kings Mountain
discharge.
REASONABLE POTENTIAL ANALYSYS (RPA) RESULTS
Reasonable potential analyses were conducted for CN, As, Cd, chlorides, Cr, Cu, Ni, Zn, and Tl,
please see attached.
The Division also considered data for other parameters of concern in the renewal application.
The majority of the parameters were not detected in the discharge and the rest were below
state water quality standards/EPA criteria.
MERCURY EVALUATION
The mercury evaluation was conducted in accordance with the Permitting Guidelines for
Statewide Mercury TMDL. WQBEL allowable concentration for this facility is 36.5 ng/ L. The
maximum detected mercury concentration during the last 5 years was 46 ng/L, which exceed
allowable concentration, but below TBEL of 47 ng/L. Based on the Permitting Guidelines for
Statewide Mercury TMDL, the annual average WQBEL limit of 36.5 ng/L and Mercury
Minimization Plan will be added to the permit. A- new mercury limit will become effective in the
5th year of the permit. The monitoring frequency will established as Quarterly.
SUMMARY OF PROPOSED CHANGES
• Based on the Permitting Guidelines for Statewide Mercury TMDL, the annual average
WQBEL limit of 36.5 ng/L will be added to the permit. A new mercury limit will become
effective in the 5th year of the permit. The monitoring frequency will be established as
Quarterly.
• Based on the Permitting Guidelines for Statewide Mercury TMDL, the Mercury
Minimization Plan special condition will be added to the permit (Please see A. (4.)).
• The monthly average limit for As has been reduced to 152.2 lig/ L based on the
protection of the aquatic life.
Fact Sheet
NPDES NC0020737 Renewal
Page 2

• The daily maximum limit for As has been reduced to 184.2 pg/L based on the
protection of the human health.
• Monitoring for As has been reduced to monthly based on the statistical analysis of the
effluent data.
• Limits and monitoring for Cd have been eliminated based on the statistical analysis of
the effluent data.
• Monitoring for chlorides has been reduced to quarterly based on the statistical analysis
of the effluent data.
• Monitoring for CN has been reduced to monthly based on the statistical analysis of the
effluent data.
• Monitoring for Cu and Zn has been reduced to monthly based on the statistical analysis
of the effluent data.
• The daily maximum limit for CN has been increased to 59.1 based on the protection of
the aquatic life.
• Daily maximum and monthly average limits for Tl have been added to the permit based
on the statistical analysis of the effluent data.
• Limits for Cu and Zn were reduced based on the statistical analysis of the effluent data.
• Proposed federal regulations require electronic submittal of all discharge monitoring
reports (DMRs) and specify that, if a state does not establish a system to receive such
submittals, then permittees must submit DMRs electronically to the Environmental
Protection Agency (EPA). The Division anticipates that these regulations will be adopted
and is beginning implementation.
The requirement to begin reporting discharge monitoring data electronically using the
NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been
added to the permit. [See Special Condition A. (5.)]

Jim- I don't know all the details, but there is a proposal to DWR that would reduce instream flow in Buffalo Creek from
12 cfs to 8.2 cfs (32% reduction), and they are asking whether this would impact wasteload allocation. Jim- please take
lead on this- look at current NH3 limit, and what that limit would be reduced to with the lower 7Q10 based on NH3
toxicity. What would be the change in IWC? This effort would probably take a few hours at most.
Jackie- how would you approach this request?
I'll set up a meeting for us during week of March 18 to discuss. Hannah is seeking feedback by 3/29. Thanks.

Subject: RE: Buffalo Creek/7Q10/WWTP
All,
My apologies but in transferring notes I flipped the 6, so the 7Q10 for the Pilot Creek WWTP NPDES is 19 cfs not 16 cfs.
Ratioing the 7Q10 value of 12 cfs from the dam down to the WWTP yields an estimated 7010 of 20.4 cfs (12 cfs / 68.1
mi2 = 0.1762 cfs/mi2; 0.1762 cfs/mi2 x 116 mi2 = 20.4 cfs).
Ratioing the 7Q10 value of 8.2 cfs from the dam down to the WWTP yields an estimated 7Q10 of 13.9 cfs (8.2 cfs / 68.1
mi2 = 0.1204 cfs/mi2; 0.1204 cfs/mi2 x 116 mi2 = 13.9 cfs).
Ratioing the 7Q10 value of 19 cfs at the WWTP up to the dam yields an estimated 7Q10 of 9.3 cfs (19 cfs / 116 mi2 =
0.1637 cfs/mi2; 0.1637 cfs/mi2 x 68.1 mi2 = 11.1 cfs).
DWQ should let DWR know if a reduction in the 7010 from 12 to 8.2 cfs will significantly impact the assimilative capacity
of Buffalo Creek.
Sorry for the error. Again, let me know if you have any additional questions.

Subject: RE: Buffalo Creek/7Q10/WWTP
Hannah,
As stated in the flow study report accompanying the EA, there is no gaging on Buffalo Creek , so the consultant created a
synthesized flow record based on existing flow records at 4 near -by USGS gages.
Based on the consultants (HDR) synthesized record, HDR determined that the 7010 at the dam was 8.2 cfs. The current
flow requirement from Moss Dam is 12 cfs, which is the 7q10 value estimated in the 70's.
There are 2 NPDES permits belonging to King's Mountain for discharge into Buffalo Creek below Moss Dam: Ellison WTP
(NC0079740), immediately below the dam, and Pilot Creek WWTP (NC0020737), just downstream of the Muddy Fork
tributary confluence.
The drainage area at the dam is 68.1 mil and 116 mil at Hwy 74, which is just downstream of the WWTP discharge. The
drainage area for Muddy Fork is 45.1 mi2.
2

.The Dam Safety rules [15A NCAC 02K .0502(6)] only allow a flow requirement of no more than the 7Q10 in the lowest
tier release from a dam.
Ratioing the 7Q10 value of 12 cfs from the dam down to the WWTP yields an estimated 7Q10 of 20.4 cfs (12 cfs / 68.1
mi2 = 0.1762 cfs/mil; 0.1762 cfs/mi2 x 116 mil = 20.4 cfs).
Ratioing the 7Q10 value of 8.2 cfs from the dam down to the WWTP yields an estimated 7Q10 of 13.9 cfs (8.2 cfs / 68.1
mi2 = 0.1204 cfs/mi2; 0.1204 cfs/mi2 x 116 mi2 = 13.9 cfs).
Ratioing the 7Q10 value of 16 cfs at the WWTP up to the dam yields an estimated 7Q10 of 9.3 cfs (16 cfs / 116 mi2 =
0.1379 cfs/mi2; 0.1379 cfs/mi2 x 68.1 mi2 = 9.3 csf).
DWQ should let DWR know if a reduction in the 7Q10 from 12 to 8.2 cfs (or 9.3 to 8.2 cfs) will significantly impact the
assimilative capacity of Buffalo Creek.
I've included some excerpts from emails during DWR's instream flow study below. I can find no evidence that Jim
consulted with DWQ during the modeling effort.
If you need to discuss further, please let me know.
Thanks.

Chris, Fred and Steve:
I've attached a spreadsheet with two flow regime options for Moss Lake, based
on the time series analyses to date. The tier 2 and tier 3 flows and triggers are
just a first cut/best guess and we will need to get model output from HDR for
the tiered approach to evaluate habitat effects. This will give them something
to evaluate from the water supply yield perspective.
Note that for the flat minimum approach I used 8.2 cfs — the 7Q10 using
unregulated flows produced by HDR modeling. However, the existing 12 cfs
minimum is supposedly based on the 7Q10 (back when the dam was
built). Before setting the bottom tier at a lower 7Q10 we will need to consult
with DWQ regarding downstream waste assimilation.
Let me know if you have any comments. I would like to send this to HDR by next
Tuesday, 2/8
Thanks

Jim,
I want to seek clarification on two points before producing the
data and passing it onto you for inclusion in your model. It is
mentioned in your email that the minimum passing flow
requirement for the dam at Moss Lake is 12 CFS however, in
previous discussion it was relayed to us that this number is a
minimum flow requirement for the WWTP plant several miles
downstream of the dam. We had been previously modeling
minimum releases out of the dam at approximately 8.9 CFS or
the 7Q10 for the synthetic inflow hydrograph. The 8.9 CFS plus
yield from the additional drainage Buffalo Creek picks up on the
way downstream should meet the 12 CFS passing flow
requirement at the WWTP.

Re: NPDES Permit # NC 0020737
Dear Mr. Weaver
The City of Kings Mountain does desire to renew the above referenced permit for
operation of our Pilot Creek WWTP.
This facility is a 6MGD Activated Sludge treatment unit. Solids handling
information is enclosed.
Since the last renewal of our NPDES permit we have made two (2) changes at Pilot
Creek Wastewater Treatment Facility:
1) We added a caustic feed system. This system was installed at the splitter
box. We began feeding caustic in our basin for pH control.
2) We replaced our manual bar screen with a mechanical bar screen to better
assist with solid removal.
Concerning the requirement for 24-hour manned operation of our wastewater
treatment plant, our plant is not now manned continuously by a certified operator.
We do have what we believe, and our past experience has proven adequate
measures in place to protect both the plant and the environment.
We hereby apply for a waiver of this rule and submit information which we believe
will demonstrate the adequacy of our system to prevent our having to add a
minimum of four persons to our staff to act as watchmen.
Thank you for your consideration in the above matters. If you need additional
information, please call 704-734-4525.
Sincerely,
Dennis R. Wells, Water Resources Director

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the facility's
discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are required to have
one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two species), or
the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results show no appreciable
toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include information on combined sewer
overflows in this section. AU information reported must be based on data collected through analysis conducted using 40 CFR Part 136 methods. In
addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC requirements for standard methods for
analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test conducted
during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a toxicity reduction
evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information requested in
question E.4 for previously submitted information. If EPA methods were not used, report the reasons for using altemate methods. If test summaries are
available that contain all of the information requested below, they may be submitted in place of Part E.
If no biomonitoring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to complete.
