Dear Ms. Grzyb,
As town manager and the responsible party for the Tabor City WWTP(NPDES #NC0026000,)I herein
request the renewal of our plant's NPDES discharge permit.The plant has not been modified since the
last renewal but repairs to the existing equipment are imminent. We will soon repair the piping associated
with one clarifier to increase its efficiency in solids removal but treatment capacity and functioning of the
plant will remain the same.
Attached are signed originals and the required copies of the completed NPDES application Form 2A with
exhibits, and a statement from our sludge handlers.
Please contact me with any further requirements you may have.
Thank you

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 E.4 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 E.4 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.

Subject: Issuance of NPDES Permit Renewal
Permit No. NC0026000
Town of Tabor City WWTP
Columbus County
Facility Class III
Dear Mr. Leonard:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued
pursuant to the requirements of North Carolina General Statute 143-215.1 and Memorandum of
Agreement between North Carolina and the U.S. Environmental Protection Agency dated October
15, 2007 (or as subsequently amended).
No changes were made to the draft permit sent to you on July 15, 2015. The final permit
authorizes the Town of Tabor City to discharge wastewater from Tabor City WWTP to an unnamed
tributary of Grissett Swamp, a class C Swamp water in the Lumber River Basin. The permit
includes discharge limitations/ or monitoring for flow, BOD5, ammonia nitrogen, total suspended
solids (TSS), dissolved oxygen, pH, temperature, total residual chlorine, fecal coliform, total
nitrogen,total phosphorus, mercury, copper, and zinc.
As identified previously, the renewal permit contains the following significant changes from
your current permit:
• 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
your NPDES permit. [See Special Condition A.(5.)]
For information on eDMR, registering for eDMR and obtaining an eDMR user account, please
visit the following web page: http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr.
For information on EPA's proposed NPDES Electronic Reporting Rule, please visit the
following web site: http://www2.epa.gov/compliance/proposed-npdes-electronic-reporting-rule.
The Division recognizes that the Town is currently submitting eDMRs. This requirement is
being inserted into all NPDES permits and should be considered a formality.
• Effluent sampling data for total copper and zinc showed reasonable potential to violate NC
Water Quality Standards (WQSs). Copper and zinc are action level parameters and limits are
1601 Mail Service Center,Raleigh,North Carolina 27699-1601
Phone:[phone] Internet:www.ncdenr.gov
An Equal Opportunity 1 Affirmative Action Employer—Made in part by recycled paper

applied in conjunction with toxicity test results. Since this facility is passing its toxicity tests,
limitations for copper and zinc were not put in the permit. However, monitoring was maintained
in the permit at a reduced monitoring frequency of quarterly to coincide with toxicity testing
requirements.
• In accordance with the 2012 Mercury TMDL NPDES Guidance, mercury data from January
2010 through May 2015 was evaluated. In 2014, the annual average mercury concentration was
above both the Water Quality Based Effluent Limitation (WQBEL) of 12 ng/L and the
Technology Based Effluent Limitation (TBEL) of 47 ng/L. Between 2010 and May 2015 the
WQBEL of 12 ng/L was exceeded 13 times and the TBEL was exceeded 2 times. The mercury
limit of 12 ng/L will be maintained in the permit renewal at a sampling frequency of monthly.
This facility has shown significantly high concentrations of mercury in its effluent with 97% of
the 281 samples taken between 2010 and May 2015 greater than 1 ng/L. As a result, a Mercury
Minimization Plan (MMP) requirement has been added to this permit renewal. See section
A.(4.). Please note that 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 Division suspects the operation and maintenance problems at the WWTP result in poor
solids removal and solids buildup in the chlorine contact tank. It is likely that the mercury
violations are due to poor plant operations and maintenance. Therefore, as required by EPA in
the Administrative Orders (AO) issued to the Town of Tabor City in 2009, total mercury(as Hg,
measured in ng/L) testing shall be performed for the following wastewater categories: influent,
effluent, and Mixed Liquor Suspended Solids (MLSS) in an aeration chamber. This requirement
is listed in Section A. (1.) of the draft permit and in the MMP special condition A.(4.). The
Town of Tabor City should take mitigative measures to prevent the discharge of mercury and
track the mercury concentrations contained in the plant.
• The Mercury Reopener Special Condition in the existing permit was removed.
• In accordance with an agreement with EPA Region IV, wasteload allocations for ammonia-
nitrogen are based on a summer criterion of 1 mg/L and a winter criterion of 1.8 mg/L. Since
the WWTP is provided no dilution from the receiving stream, the monthly average effluent
limits determined for the Tabor City WWTP are 1 mg/L in the summer and 1.8 mg/L in the
winter. Using a 3:1 ratio the weekly average limits for NH3-N will be 3 mg/L in the summer
and 5.4 mg/L in the winter. These revised ammonia-nitrogen limitations were inserted into the
permit renewal. See section A. (1.). A review of effluent data during the period of 2010 through
2014 shows the WWTP is able to meet these limitations.
• According to the Tabor City WWTP updated components list, the deep-sand tertiary filtration
system has been inactive since 2013. The existing special condition A. (5.) has been removed
from the permit.
• Existing special conditions A. (4.)and A. (6.) have been removed from the permit.
• A Special Condition requiring a Facility Assessment and Corrective Action Plan has been added
to the permit. No later than 7 months after the effective date of this permit, the Permittee shall
submit to the Division of Water Resources a Facility Assessment and Corrective Action Plan as
described in special condition A. (6.).

• Some of the wording has changed in Special Condition A. (2.), Chronic Toxicity Permit Limit,
please review each paragraph carefully.
• Special Condition A.(3.) has been modified to include the specific three years in which the
Effluent Pollutant Scans shall be performed (2016, 2017, and 2018). In addition, at the end of
the Special Condition, 2nd species Toxicity Testing Requirements for municipal permit
renewals per Federal Regulations [40 CFR 122.21(j)(5)] have been added.
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 (6714 Mail Service Center, Raleigh,North Carolina 27699-6714). Unless
such demand is made,this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the
legal requirements to obtain other permits which may be required by the Division of Water
Resources or any other Federal, State, or Local governmental permits that may be required.
If you have questions concerning this permit,please contact Yang Song by e-mail

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(jx5). 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
1623 Mail Service Center
Raleigh,North Carolina 27699-1623

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
1623 Mail Service Center
Raleigh,North Carolina 27699-1623
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 of MMP implementation 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.
In addition to mercury effluent monitoring,total mercury(as Hg,measured in ng/L)testing shall be performed at the
Wastewater Treatment Plant influent and on the Mixed Liquor Suspended Solids(MLSS)in an aeration chamber.
Testing shall be performed monthly and all samples(influent,effluent,and MLSS)taken at the same locations for
consistency. Sampling and lab testing procedures shall be consistent with permit requirements and EPA accepted test
methods for testing mercury in wastewater.Testing shall commence within the month that this permit becomes
effective.After three years from the effective date of this permit, if the Permittee has demonstrated consistent
compliance with the mercury limitation,the Permittee may request the Division to review and adjust mercury sampling
requirements.A summary of all mercury sampling results(influent,effluent,MLSS), along with a discussion on the
concentrations documented throughout the plant and the steps taken to reduce mercury in the effluent, shall be included
with the MMP implementation results and submitted with the next permit renewal.
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 submit DMRs electronically to the
Environmental Protection Agency(EPA). The Division anticipates that these regulations will be adopted and is
beginning implementation in late 2013.

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/ipuiedmr
Regardless of the submission method,the first DMR is due on the last day of the month following the issuance of the

BACKGROUND
Tabor City Wastewater Treatment Plant(WWTP)serves a population of about 4,429 people. It does not
have a Pretreatment Program and no Significant or Categorical Industrial Facilities were identified in the
renewal application.The Permittee's 5-year NPDES permit expired August 31,2014 and has been
administratively continued.The application for permit renewal(Form 2A)was received on March 3,
2014.
The Tabor City WWTP is a 1.1 MGD publicly owned treatment works(POTW)utilizing a Grade III
activated sludge wastewater treatment facility to treat domestic wastewater with some wastewaters from
small commercial industry. The WWTP utilizes: a triplex influent pumping station,Parshall flume,
mechanical bar screen,manual bar screen,grit remover,"aerated"sludge holding basin,side-stream
emergency surge basin, one extended-aeration activated sludge basin with mechanical surface aerators
(low basin),one contact stabilization activated sludge basin with mechanical surface aerators(upper
basin),two secondary clarifiers(may be operated in parallel or in series), influent and effluent samplers,
gaseous chlorine/sulfur-dioxide feed system,chlorine contact basin,influent and effluent ultrasonic flow
meter, and a back-up power generator. The Land Application Permit WQ0001936 for the Town of Tabor
City is still valid;however,currently the City uses McGill Environmental Systems to handle dewatered
biosolids from the WWTP for processing at the McGill Sampson Composting Facility under permit
WQ00006816.

Waste Load Allocation(WLA)
The Division prepared the last WLA model for the receiving stream in June 1994. The permit effluent
limits for BOD5(5 mg/L in the summer period and 10 mg/L in the winter period)at 1.1 MGD were based
on this WLA.
Current Effluent Characteristics
The Tabor CityWWTP's average flow was 0.51 MGD duringthe calendaryear of 2014,which represents
g p
46%of the permitted flow.Monthly average flows ranged from 0.37 to 0.66 MGD.

EVALUATION OF COMPLIANCE DATA
DMR Review
Discharge Monitoring Reports(DMRs)have been reviewed for the period of January 2010 through
December 2014.The facility had multiple permit limit violations for mercury,total residual chlorine,
fecal coliform,and ammonia-nitrogen. See Table 2 for details.

Mercury
On October 15,2009,EPA issued an Administrative Order to the Town of Tabor City requiring them to
develop a Mercury Minimization Plan and to come into compliance with effluent limits by July 31,2010.
In the following years,compliance with the mercury limitation improved with no violations in 2011,one
in 2012,and none in 2013.The Division approved the removal of the UV equipment in June 2013,but it
was noted during inspections on 7/17/14 and 8/7/14 that the equipment was still in place.This is
significant since Tabor City WWTP attributed all three of the mercury limit violations that occurred in
Oct.2014 to bulb breakage in the UV system. No explanations were offered by the Town for the other
Fact Sheet—Tabor City 2015 Renewal

three exceedances noted in 2014.The mercury concentrations reported for these three weekly average
violations are as follows: 1/18/14, 14.8 ng/L; 5/24/14, 14.7 ng/L; 12/20/14,2320 ng/L.These
exceedances are very high and the violations continued after the UV system was removed in Nov. 2014
and replaced with chlorine disinfection. In 2015,two mercury weekly average violations were reported as
follows: 5/9/15,38.1 ng/L;5/16/15, 14.3 ng/L.
Total Residual Chlorine
It should also be noted that Tabor City WWTP was on EPA's watch list for total residual chlorine
violations in 2010. However,the Permittee has been in compliance with its total residual chlorine limit
since Jan. 2011.
Fecal Coliform and ammonia-nitrogen
The exceedance of the fecal coliform weekly average limit in July 2013 was reported as due to solids
buildup in the contact chamber.The violation of the ammonia-nitrogen monthly average in Dec.2010
was stated as being caused by unusually cold temperatures.
Inspections
The WiRO conducted three(3)routine compliance inspections with two(2)additional follow-up
compliance inspections since the existing permit was issued on March 1,2010.These inspections found
the facility to be marginal or unreliable. The inspections performed in July and Aug.of 2014 listed
numerous operation and maintenance issues. See Table 3 for details.
Table 3.Issues from WiRO Staff Report
a. Diversion to the side-stream surge basin of high flows
Operation b. Operational issues in clarifier 1 (upper train)
c. Aeration for aerated sludge holding basin is not adequate
d. Sampling protocol is questionable
a. Solids build-up in chlorine contact chamber
Maintenance b. Sludge hauling records
c. No annual performance reports
d. No collection system evaluation reports and inadequate quarterly reports
Existing permit special conditions
Special condition A.(4.)required the submittal of a Headworks/Pump Station Evaluation,within 90 days
of the 2010 permit's effective date. It appears no submittal was received from the Town on this matter.
Special condition A.(5.)required the Permittee to bring the Tertiary Sand Filters online within 90 days of
the 2010 permit's effective date. The filtration system has been inactive since 2013.
Special condition A. (6.)required the submittal of a Sewer Collection System Evaluation and
Remediation Plan along with Quarterly Progress reports. The Town of Tabor City claims an Evaluation
was submitted but the Regional Office has no record of receiving such an Evaluation. In addition,the
Regional staffs have stated that the Quarterly Progress reports are insufficient. Upon further
investigation,the initial phase of a Sanitary Sewer Evaluation Study was performed by Hobbs,Upchurch
&Associates(titled: Inflow and Infiltration Analysis, 1/4/13) for the Town of Tabor City;however,the
evaluation did not include gathering data to determine high priority areas and it did not establish a
rehabilitation plan to remedy the surge problems. A Complex Enforcement case has been developed by
the Central and Regional Office Staff to address violations and hopefully initiate actions needed to
remedy issues outlined above.
Note,that in May 2012, due to a heavy rain, 3,600 gallons of untreated sewerage escaped from a manhole
near the end of Burns Street in Tabor City during a six-hour period.

ToxicityTesting
g
Since January 2010 the facility has passed 23 of 25 chronic toxicity tests and 3 of 4 fathead minnow
second species tests.
EVALUATION OF INSTREAM DATA
Instream monitoring data from January 2012 through December 2014 was reviewed.The facility samples
temperature and dissolved oxygen upstream and downstream of its discharge. Upstream and downstream
samples showed no temperature increase that exceeded the 2.8°C water quality standard. The discharge
did not appear to have any impact on temperature. Due to swampy conditions,there were 153 upstream
samples and 64 downstream samples showing DO concentrations below the minimum instantaneous
value of 4 mg/l. Among the 64 downstream low DO values,58 occasions coincide with low DO values
upstream. Additionally,the WWTP had no permit limitation violations for DO and BOD5 during the
period of 2011 through 2014. It appears that the WWTP discharge had minimal impact on downstream
DO. See attachment titled Tabor City WWTP Upstream and Downstream Monitoring Summary.
REASONABLE POTENTIAL(RP)ANALYSIS AND EFFLUENT POLLUTANT SCANS
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 2012 through December 2014.
Reasonable potential analyses were conducted for copper and zinc. See attached RPA results and data.
• Copper and Zinc—the maximum predicted values for total copper and total zinc demonstrated a
reasonable potential to exceed both the chronic and acute allowable concentrations. Both
parameters have action level standards and are reviewed in conjunction with toxicity testing
results. The facility has passed 23 of 25 toxicity tests since January 2010; therefore, no limits for
copper and zinc were added but monitoring was maintained in the permit with the monitoring
frequency reduced to quarterly.
Effluent pollutant scans were performed in the 3`a quarter of 2011, the 4th quarter of 2012, and the 4th
quarter of 2013. Data from these three annual effluent pollutant scans was evaluated and chloroform,
dichlorobromomethane, and total phenolic compounds were detected in addition to copper and zinc.None
of the metals detected were greater than the concentrations analyzed in the RPA discussed above.
Chloroform and dichlorobromomethane were detected at levels less than the HH standard. Total phenolic
compounds were detected at a level less than the NC Aesthetic WQS.
AMMONIA-NITROGEN
In accordance with an agreement with EPA Region IV, wasteload allocations for ammonia-nitrogen are
based on a summer criterion of 1 mg/L and a winter criterion of 1.8 mg/L. Since the WWTP is provided
no dilution from the receiving stream, the monthly average effluent limits determined for the Tabor City
WWTP are 1 mg/L in the summer and 1.8 mg/L in the winter. Using a 3:1 ratio the weekly average limits
for NH3-N will be 3 mg/L in the summer and 5.4 mg/L in the winter. These revised ammonia-nitrogen
limitations were inserted into the permit renewal. A review of effluent data during the period of 2010
through 2014 shows the WWTP is able to meet these limitations.
MERCURY TMDL EVALUATION
In accordance with the 2012 Mercury TMDL NPDES Guidance,mercury data from January 2010 through
May 2015 was evaluated. In 2014, the annual average mercury concentration was above both the Water
Quality Based Effluent Limitation (WQBEL) of 12 ng/L and the Technology Based Effluent Limitation
(TBEL) of 47 ng/L. See Table 4. Between 2010 and May 2015 the WQBEL of 12 ng/L was exceeded 13
times and the TBEL was exceeded 2 times.The mercury limit of 12 ng/L will be maintained in the permit
renewal at a sampling frequency of monthly.
Fact Sheet—Tabor City 2015 Renewal
NPDES Permit NC0026000
Page 4

This facility has shown significantly high concentrations of mercury in its effluent with 97% of the 281
samples taken between 2010 and May 2015 greater than 1 ng/L.As a result,a Mercury Minimization Plan
(MMP)requirement has been added to this permit renewal. See section A.(4.). Please note that 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 Division suspects the operation and maintenance problems at the WWTP result in poor solids
removal and solids buildup in the chlorine contact tank. It is likely that the mercury violations are due to
poor plant operations and maintenance. Therefore, as required by EPA in the Administrative Orders(AO)
issued to the Town of Tabor City in 2009, total mercury (as Hg, measured in ng/L) testing shall be
performed for the following wastewater categories: influent, effluent, and Mixed Liquor Suspended
Solids(MLSS)in an aeration chamber.This requirement is listed in Section A. (1.)of the draft permit and
in the MMP special condition A.(4.). The Town of Tabor City should take mitigative measures to prevent
the discharge of mercury and track the mercury concentrations contained in the plant.

ADDENDUM TO FACT SHEET(SEPTEMBER 16,2015)
A meeting between Municipal Engineering Services Company,P.A. (Michael McAllister etc.)and NC
DEQ/DWR Wastewater Branch(Julie Grzyb etc.)was held on August 6,2015.Mr. Michael McAllister
stated that Municipal Engineering was working with Tabor City to solve their operation and maintenance
issues. It was told that Tabor City is planning to have a full hydraulic analysis on their facility,which
could contribute to the special condition of Facility Assessment and Corrective Action Plan. Meanwhile,
' Municipal Engineering is preparing funding applications for Town of Tabor City.

In the meeting,Municipal Engineering expressed concerns about the requirements and actual workload of
MMP.The Division staffs explained the requirements and necessity of MMP for Tabor City WWTP.A
summary of influent mercury sampling results from October 2014 to January 2015 was provided by the
Division.This report showed several high mercury concentration samples from dentist office manhole as
well as Atlantic Printing manhole. In addition,the Division showed the willingness to further discuss
MMP implementation. However,no formal comments were received from Tabor City or Municipal
Engineering before the public notice due date.
