Dear Mr. Weaver

i OORESVILLE REGIOid,AL OFFICE
The City of Dings 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 s6lid 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 cortsideration in the above ratters. if you need additional
information, please call 704-734-4525.
Sincerely,

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. All 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 EA for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods. If test summaries are
available that contain all of the information requested below, they may be submitted in place of Part E.

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. All 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 EA for previously submitted information. If EPA methods were not used, report the reasons for using alternate
methods. If test summaries. are available that contain all of the information requested below, they may be submitted in place of Part E.

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. All 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 EA for previously submitted information. If EPA methods were not used, report the reasons for using alternate
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

Subject: r "Draft NPDES Permit
Permit NCO020737
Pilot Creek WWTP
Cleveland County
Dear Mr. Downey:
Enclosed with this letter is a copy of the draft NPDES permit for your facility. I
encourage you to review the draft carefully to ensure thorough understanding of the
information, conditions, and requirements it contains.
The following changes have been made to your new permit:
• Updated monthly average ammonia limits have been added to your permit. These
limits are based on summer and winter low flow conditions and the instream waste
concentration (IWC) of your effluent during those times. The calculated limit for the
summer is 2.6 mg/L and the winter limit is 8.9 mg/L.
• Weekly average ammonia limits of 7.8 mg/L (summer) and 26.7 mg/L (winter) have
been placed in your permit. This is based on a new North Carolina ammonia policy
that requires that a weekly average limit based on a 3:1 ratio with the monthly
average limit be implemented in all municipal permits.
• An annual pollutant scan has been added to your permit. By performing this scan
concurrent with your toxicity test (at different times of the year), you will be able to
collect sufficient data for the new renewal application required by the
Environmental Protection Agency (EPA).
• Monitoring for chromium, cyanide, fluoride, lead, and mercury has been eliminated.
A reasonable potential analysis of effluent data from your facility indicates that the
Pilot Creek WWTP effluent does not show the potential to exceed water quality
criteria for any of the above parameters. You are still required to monitor these
parameters through your pretreatment Long Term Monitoring Plan.
• The limits for cadmium have been changed to reflect current North Carolina and
federal water quality criteria. The daily maximum limit is now 15 µg/L and the
weekly average limit is 6.1 µg/L.
• Monitoring for nickel has been reduced to monthly. A reasonable potential analysis
of effluent data from your facility indicates that the Pilot Creek WWTP effluent does
not show the potential to exceed water quality criteria for nickel. Given the
relationship between effluent toxicity and the presence of nickel in your effluent,
this parameter cannot be eliminated from your permit, but monitoring has been
reduced.
Please remember than beginning next month, you will be required to monitor for
mercury using EPA Method 1631. You should have already received a letter from the
Division to this effect. A copy is available on the NPDES website at:

There shall be no discharge of floating solids or visible foam in other than trace amounts.

FA(2-)CHRONIC TONICITY PERMIT LIMIT (QUARTERLY) Permit NC0020737
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 33%.
The permit holder shall perform at a minimum, guarterlu 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 TGP313 for the pass/fail results and THP313 for the Chronic Value. Additionally, DWQ Form AT-3
(original) is to be sent to the following address:
Attention:North Carolina Division of Water (,duality
Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental 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
Environmental Sciences Branch at the address cited above.
Should the Permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened
and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later than
the last day of the month following the month of the initial monitoring.

BACKGROUND
DENR/DWQ
FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES No. NCO020737
The Pilot Creek WWTP is a Class IV facility with a permitted flow of 6.0 MGD. The plant treats
wastewater from residential, commercial and industrial sources. The permit was originally
issued on January 22, 1999 and expired on August 31, 2003. The Permittee submitted EPA
Form 2A on February 26, 2003 in order to request renewal of the permit.
Prior to renewal, the City lost a major industry, Anvil, and this has severely reduced the flow
through the plant. Excess flow, which was previously sent to the City of Gastonia's Crowders
Creek WWTP, will now be treated at the Pilot Creek facility. The City has a full pretreatment
Long Term Monitoring Plan (LTMP) which will continue to be implemented in the coming
permit term.
The facility has experienced a number of compliance problems in the last permit term, primarily
for toxicity failures.
Instream Monitoring, Verification of Existing Conditions and DMR Data Review
This facility discharges to Buffalo Creek in subbasin 043-08-05 of the Broad River Basin.
Buffalo Creek is classified C waters at the point of discharge and is not on the 2002-303(d) list.
Kings Mountain is required to sample upstream and downstream of the discharge for dissolved
oxygen, temperature, fecal coliform, and conductivity. Plots of these data, which were culled
from Discharge Monitoring Reports (DMRs) dating from January 2001-July 2003, are attached
to this fact sheet. Little difference was noted between upstream and downstream values for
dissolved oxygen, temperature, and fecal coliform. Moreover, all of the instream values for
dissolved oxygen were above the stream standard of 5.0 mg/L and the majority of the fecal
coliform values were below 200 cfu/100 mL. There was a noticeable difference between the
upstream and downstream conductivity values.
Effluent DMR data from January 2001 through May 2003 were reviewed. Data for conventional
parameters are summarized in Table 1. For the most part, the Permittee maintained compliance
with the permit limits for those parameters.

A review of the metals (from both the DMRs and Pretreatment data) data was also performed.
These are discussed in the Reasonable Potential Analysis section.
Correspondence
The Mooresville Regional Office (MRO) conducted several site visits during this permit term to
evaluate compliance. Notices of Violation (NOVs) were issued in conjunction with some of
these inspections for permit limit violations. In all, twenty-one NOVs have been issued to the
City of Kings Mountain since March 1999. Twenty of these were issued at least in part due to a
toxicity violation or late submittal of toxicity results. One was for late submittal of the annual
fees. Miscellaneous violations of lead, cadmium and TSS limits were associated with two
NOVs.
As a result of the consistent toxicity failures, Kings Mountain fell under the first phase of the
action level policy in 2000. A Toxicity Identification Evaluation was submitted to the MRO.
The Permittee concluded that nickel was the cause of the effluent toxicity based on tests
employing EDTA for chelation. The City was then planning on pursuing source reduction, in
part by working with its SIUs.
PERMITTING STRATEGY
Waste Load Allocation (WLA)
The Division prepared the last WLA for the previous permit renewal. The previous and current
effluent limits were based on guidelines and water quality standards. The Division has judged
previous parameters and limits to be appropriate for renewal with some exceptions. Changes to
toxicant monitoring are discussed in the Reasonable Potential Analysis section, with the
exception of ammonia.
The previous permit contains a summer limit for ammonia that appears to be based on the results
of Level B model. When assessing ammonia with respect to instream toxicity, however, it is
evident that both summer and winter limits are necessary. Based on the Instream Waste
Concentration (IWC), a summer monthly average limit of 2.6 mg/L and a winter monthly
average limit of 8.9 mg/L should be implemented. Moreover, weekly average ammonia limits
based on a 3:1 ratio with the monthly average (but no higher than 35.0 mg/L) will be
implemented in this permit. This is a new statewide policy that resulted from EPA requirements.
The resulting summer weekly average limit will be 7.8 mg/L and the winter limit will be 26.7
mg/L.
Fact :She:
NPDES NCC 0207.7 Rentae, m

In addition, an annual pollutant scan will be added such that the Permittee can collect the
necessary data required by EPA Form 2A throughout the permit term. This condition is now
standard on all major municipal permits in North Carolina.
Reasonable Potential Analysis (RPA)
The Division conducted EPA -recommended analyses to determine the reasonable potential for
toxicants to be discharged by this facility, based on DMR data from January 2000-May 2003.
Calculations included parameters listed in the previous permit and pre-treatment documents to
include: arsenic, cadmium, chloride, chromium, cyanide, fluoride, lead, mercury, nickel,
selenium, silver, copper, and zinc.
Results suggest no reasonable potential for the facility to discharge arsenic, chromium, cyanide,
fluoride, lead, mercury, nickel, silver, and selenium. Monitoring for chromium, cyanide, lead,
mercury, and fluoride, currently performed through the NPDES permit, may be eliminated from
the permit, as they are required parameters to be monitored through the Pretreatment Long Term
Monitoring Plan (LTMP). Nickel monitoring will be maintained, but reduced to monthly, due to
its association with toxicity problems.
Effluent from the facility did demonstrate reasonable potential to exceed water quality criteria for
cadmium, zinc and copper. All limits and monitoring associated with these parameters in the
current permit will be carried over into this permit term. A daily maximum limit for cadmium of
15 µg/L will be added to the permit.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies, the following will be incorporated into the permit:
• New monthly and weekly average ammonia limits (both summer and winter)
• Annual pollutant scan
• Elimination of the chromium, cyanide, fluoride, lead, and mercury monitoring requirements
(Permittee will continue to monitor these parameters through the LTMP).
• Addition of daily maximum limit for cadmium
• Reduction of nickel monitoring to monthly
New Weekly Average and Daily Maximum limits are derived from the latest NC/EPA policies
considering'/a FA Vs and allowable concentrations based on reasonable potential.

• 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
5t' 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 pg/L based on the
protection of the aquatic life.

• The daily maximum limit for As has been reduced to 184.2 }ig/ 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.)]

In reference the NOV 40 CFR 503, all sludge generated at our
plant for the period in question, and to date, was removed by
Cleveland Container Service, Inc. and incorporated into their
solid waste landfill.
However, we wish to retain the permit (WQ0005065) for our
dedicated sludge landfill so we are not at the mercy of
contract removal companies, and have room to negotiate.
Due to the required distance from property lines, we have
very little usable space in our landfill and plane to reserve
that for emergencies, but the contractors do not have to be
informed of this fact.
We hope this satisfies the requirements of the NOV. If there
are additional questions or need for further information,

Subject: Final NPDES Permit
Permit No. NCO020737
Pilot Creek WWTP
Cleveland County
In accordance with the application for a discharge permit received on June 26, 1998, the Division is
forwarding herewith the subject NPDES permit. This permit is issued pursuant to the requirements of
North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina
and the U.S. Environmental Protection Agency dated December 6, 1983., and as subsequently amended.
Please note the following changes from the previous permit (as indicated in the draft) have been finalized:
Monitoring frequencies for Total Nitrogen and Total Phosphorus were changed from monthly to
quarterly (per revised 2B .0500 regulations for Broad River Basin).
Toxicity language has been updated.
Limits for cyanide, chromium, and nickel were removed, and monitoring frequencies for these
parameters were reduced from weekly to 2/month (per Division policy for Class IV facilities). Based
on a statistical analysis of past data for the reasonable potential to exceed water quality standards
(Reasonable Potential Analysis), limits for these parameters are not necessary during this permit
cycle.
Mercury Limit. and Monitoring
In response to comments in your renewal letter dated June 26, 1998, mercury monitoring could not be
eliminated from this permit. A Reasonable Potential Analysis of mercury data from this facility
demonstrated the potential for a water quality standard violation in the stream, and so a limit is included
for the next permit cycle. The North Carolina water quality standard for mercury is 0.012 µg/l, from
which the daily maximum limit for this facility's flow capacity is derived (0.04 µg/1). We cannot
multiply this number by "10" to obtain a different limit, as the value would not be based on any standard.
Should analysis of mercury data indicate a limit is no longer necessary at the next renewal, the limit may
be removed at that time.
Because the mercury limit for this facility must reflect the water quality standard, this limit cannot be
adjusted because the quantitation limit is ,higher. Please note, however, that the quantitation limit for
mercury is specified on the effluent page as 0.2 µg/l. If measured levels of mercury are below 0.2 µg/l,
these levels will be considered zero for compliance purposes.
In the past, other North Carolina facilities having problems with unexplained mercury "hits" have begun
taking duplicate and triplicate samples to ensure confidence in the data collected. If multiple samples are
analyzed, the average of those results should be reported. In addition, clean sampling techniques help
reduce risk of sample contamination.

mercury adopted by North Carolina (listed in NCAC T15A: 2B .0200) is established to protect aquatic
life and is based on the chronic effectsof this metal. Not only does mercury interfere with healthy
aquatic life, but once it is discharged into the environment, mercury readily forms the compound methyl -
mercury and will accumulate in fish tissue. Humans may consume mercury -contaminated fish and
potentially suffer adverse health effects.
In response to your comments regarding mercury limits in South Carolina, South Carolina's Department
of Health and Environmental Control (SCDHEC) communicated to us that theiraquatic life standards for
mercury in fresh water are 0.012 µg/1 and 2.4 µg/l (protecting for chronic and acute effects, respectively).
Although North Carolina differs in how it assigns mercury monitoring and limits in permits, South
Carolina similarly considers its own standards when imposing any limits on discharges.
At present, over 25 facilities in North Carolina have mercury limits in their NPDES permits. Virtually all
municipalities with pretreatment programs in North Carolina and several industries where mercury is a
pollutant of concern are required to monitor for mercury. There are currently three (3) significant
industrial users (SIUs) that discharge to the Pilot Creek WWTP that possibly have mercury in their waste
flow. This means that mercury is a pollutant of concern at this facility, and monitoring must remain in
the permit; otherwise, no data would exist for the Division to determine whether or not a limit is
necessary in the future.
SummerlWinter Months
The summer and winter month intervals in this permit are established through general statute, based on
temperature trends across the State and are the same for every facility with seasonal differences in
monitoring and/or limits. Since these requirements are adopted by rule, only a legal variance can change
them in your permit. In response to your comment, the month of April is already considered a summer
month in North Carolina NPDES permits.
Also, for future reference, please feel free to cross out Centigrade units and write in Fahrenheit units
when filling out the renewal application. We will consider this change when updating our renewal forms.
If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30)
days following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative
Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such demand is made,
this decision shall be final and binding.
Please take note that this permit is not transferable. Part II, E. 4. addresses the requirements to be
followed in case of change in ownership or control of this discharge. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Land Resources or any
other Federal or Local governmental permit that may be required.

AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A.(2). CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in the "North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised November 1995, or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is
33.0% (defined as treatment two in the procedure document). The permit holder shall perform quarterly monitoring
using this procedure to establish compliance with the permit condition. The tests will be performed during the M071DIS
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.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B. Additionally,
DWQ Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of Water Quality
4401 Reedy Creek Road
Raleigh, North Carolina 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the
permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility
name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the
comment area of the form. The report shall be submitted to the Environmental Sciences Branch at the address cited
above.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will begin
immediately until such time that a single test is passed. Upon passing, this monthly test requirement will revert to
quarterly in the months specified above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly monitoring
will begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water
Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include
alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid
test and will require immediate follow-up.testing to be completed no later than the last day of the month following the
month of the initial monitoring.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority
The Director of the Division of Water Quality.
2. DEM or "the Division"
Means the Division of Water Quality, Department of Environment, Health and Natural Resources.
3. EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC
1251, et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge' is defined as the total mass of all daily discharges sampled
and/or measured during a calendar month on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found
each day of the month and then dividing this sum by the number of days the tests were
reported. The, limitation is identified as "Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured
during such week. It is, therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the week and then dividing this sum by the number of days the
tests were reported. This limitation is identified as "Weekly Average' in Part 1. of the permit.
c. The "maximum daily discharge' is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average annual discharge' is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. This
limitation is defined as "Annual Average" in Part I of the permit.

Part II
Page 2 of 14
6. Concentration Measurement
a . The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average monthly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar month. This
limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of the
daily concentration values). The daily concentration value is equal to the concentration of a
composite sample or in, the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average weekly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum .Daily Concentration". It is identified as "Daily
Maximum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily discharges
sampled and/or measured during such year (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day . The average yearly count for fecal coliform bacteria is the
geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as "Annual Average" under "Other Limits" in Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of
dissolved oxygen required to be available in the effluent prior to discharge averaged over a
calendar day. If only one dissolved oxygen sample is taken over a calendar day, the sample is
considered to be the "daily average concentration" for the discharge. It is identified as "daily
average" in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through March,
April through June, July through September, and October through December.

Part II t

7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged
monthly. It is determined as the arithmetic mean of the total daily flows recorded during the
calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when
both the sample and flow will be representative of the total discharge.
c. A "continuous flow measurement is a measure of discharge flow from the facility which occurs
continually without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for
infrequent maintenance activities on the flow device.
8. TyRes of Samples
a. Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge
and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow
recorder and totalizer, and the present gallon interval between sample collection fixed at
no greater than 1 /24 of the expected total daily flow at the treatment system, or
(3) a single, continuous sample collected over a 24 hour period proportional to the rate of flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time of
greater than 24 hours. In such cases, effluent grab samples may be collected at time intervals
evenly spaced over the 24 hour period which are equal in number of hours to the detention time
of the system in number of days. However, in no case may the time interval between effluent
grab samples be greater than six (6) hours nor the number of samples less than four (4) during a
24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken manually. Grab samples must ' be
representative of the discharge or the receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual
values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the
individual values where N is equal to the number of individual values. The geometric mean is
equivalent to the antilog of the arithmetic mean of the logarithms of the individual values.
For purposes of calculating the geometric mean, values of zero (0) shall be considered to be one
(1).
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration
times its respective flow divided by the summation of the respective flows.

Part II
Page 4 of 14
10. Calendar Day
A calendar day is defined as the period from midnight of one day until midnight of the next day.
However, for purposes of this permit, any consecutive 24-hour• period that reasonably represents
the calendar day may be used for sampling.
11. Hazardous Substance
A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to Section
311 of the Clean Water Act.

a. Definitions
(1) 'Bypass" means the -known diversion of waste streams from any portion of a treatment
facility including the collection system, which is not a designed or established or operating
mode for the facility.
(2) "Severe property damage" means substantial physical damage to property, damage to the
treatment facilities which causes them to become inoperable, or substantial and permanent
loss of natural resources which can reasonably be expected to occur in the absence of a
bypass. Severe property damage does not mean economic loss caused by delays in
production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient operation. These
bypasses are not subject to the provisions of Paragraphs c. and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall
submit prior notice, if possible at least ten days before the date of the bypass; including an
evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
required in Part II, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against
a permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliarytreatment
facilities, retention of untreated wastes or maintenance during normal periods of
equipment downtime. This condition is not satisfied if adequate backup equipment should
have been installed in the exercise of reasonable engineering judgment to prevent a bypass
which occurred during normal periods of equipment downtime or preventive maintenance;
and
(0 The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three

caused by operational error, improperly designed treatment facilities, inadequate treatment
facilities, lack of preventive maintenance, or careless'or improper operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with such
technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs, or other relevant evidence that:
(1) An upset occurred and that the permittee can identify the cause(s) of the upset;
(2) The permittee facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this permit.
(4) The permittee complied with any remedial measures required under Part 11, B. 2. of this
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has
the burden of proof.

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 TGP313 for the pass/fail results and THP313 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

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 NCO020737
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)]

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 122.216)(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

MOORESVILLE REGIONAL OFFICE
Good morning Ori,
For some reason the email I sent yesterday, in regard to the incident that took place, did not send. So here is a
description of what happened.
Around 12:00p.m. on Wednesday, June 21st, 2017, a operator error occurred which caused an overload in our #3
system. Operators were ask to begin taking down system #4 for cleaning. During this time the operator did not put the
'cap' on the basin outfall, this allowed flow to. continue into the clarifier where we were pumping from and into basin #3.
This resulted in an overload on the #3 system. Causing solids to wash out of the final clarifier (#3), into the chlorine
contact chamber. After inspection of the outfall into Buffalo Creek, this did not appear to upset the creek.
Around 12:45/1:00pm, #3 system was shut down to stop flow, #4 system was put back into operation. No solids were
washing out at this point. Disciplinary actions have been taken against the operator due to neglect. Operators are fully
aware of the importance in monitoring all systems during an event such as this. I can assure you this will not take place
again.
Attached is the picture that was taken as soon as I got off the phone with you. If you have any questions, feel free to
give me a call.
Sincerely,
