Subject: Issuance of NPDES Permit NC0026000
Tabor City WWTP, Grade III
Off Hwy 701 Bypass
Columbus County
Your Honor:
The Division of Water Quality (the Division) hereby issues the attached NPDES permit for the subject
facility. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and
the Memorandum pf Agreement between North Carolina and the U.S. Environmental Protection Agency
dated October 15, 2007, or as subsequently amended.
Increased Monitoring for Fecal Coliform.— I response to your comments on the draft permit (received
January 19, 2010), the Division concurs with your proposal to sample fecal conform on Monday through
Thursday (4 samples per week), with an additional fifth sample to be collected on Fridays during any
"abnormal rainfall" condition. We applaud your willingness to sample all five (5) samples, as required,
during peak -flow hours (between 09:00 and 14:00). Please note that the Division defines high -flow
conditions on Fridays as "any influent flow exceeding permitted 1.1 MGD." Therefore, we have adjusted
your permit accordingly and revised the effluent -page footnote. After one year you may request the
Division to review monitoring and make adjustments, as warranted [see permit Section A. (1.)].
Permit Special Conditions A. (3.) — As observed during DWQ's onsite inspections, the influent pumping
station (a 3-pump system) cycles "on and off' automatically, adding pumps in response to progressively
higher flows. However, more than one pump overwhelms the WWTP headworks causing raw sewerage
overflow and spills to the receiving -stream environment. High influent flow may be diverted to the new
EQ basin only if an operator is present to manually divert the flow. Your Operator in Responsible
Charge (ORC) confirmed that the Pump Station is beyond her job responsibilities.
DWQ will require your further review of this influent pump station with a holistic regard to the WWTP
from headworks to outfall. We therefore have retained permit Special Conditions A. (3.) requiring your
findings and recommendations to solve overflow issues at the plant headworks. Please note that you are not
required to implement, but provide findings and recommendations for modifications and/or operational
adjustments within 90 days of the permit effective date. Your report may include, but is not limited to, an
Engineering Analysis of pipe -sizing, concrete fixtures, grit chamber, and bar screen, specifically addressing
the impact of peak flows routed via the influent pumping station.
Permit Special Condition A. (4.) — Also, please be reminded that you must address immediately the
maintenance issues at your tertiary deep -sand filter system, likewise complying with this Special Conditions
within 90 days of the permit effective date.

UV Disinfection - Total Residual Chlorine (TRC) — The Division notes that your installation and repairs \
to the Ultraviolet (UV) disinfection system have been only moderately successful in complying with the
fecal coliform permit limit, and you have resorted to alternate disinfection using a backup gaseous chlorine.
You may wish to reevaluate this inadequate UV operation. The Division has therefore retained the TRC
limit, anticipating continued use, and added a footnote to the effluent monitoring table, Section A. (1.).
However, because of difficulties quantifying TRC in a wastewater matrix, TRC values reported below 50
ug/L will be considered compliant with this permit, per statewide policy governing chlorine.
Collection System Evaluation and Remediation Plan — Within 30 months of the permit effective date,
Tabor City shall design, fund, and implement a Sewer Collection System Evaluation and Remediation Plan.
This Plan shall present methods to evaluate stormwater inflow and infiltration (UI), present findings, and
implement studies and remediation schedules, as needed. Tabor City must report to the Division on
conditions and progress by means of a Quarterly Progress Report to be submitted no later than the end of
each calendar quarter, beginning with the period following the permit effective date. Failure to meet this
Special Condition will constitute a violation of this permit and will subject you to civil penalty assessment.
Finally, please be advised that you must report any sanitary sewer spill or overflow to the Wilmington
Regional Office. Failure to report a wastewater loss to the environment constitutes a violation of your NPDES
permit, and any unreported spill will subject you to civil penalty assessment.
If any parts, measurement frequencies, or sampling requirements contained in this permit are unacceptable,
you have the right to an adjudicatory hearing, upon written request submitted within thirty (30) days after
receiving this letter. Your request must take the form of a written petition conforming to Chapter 150B of
the North Carolina General Statutes, and you must file it with the office of Administrative Hearings, 6714
Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is made, this permit shall
be final and binding.
This permit is not transferable except after notifying the Division of Water Quality. The Division may
require modification, or revocation and re -issuance of this permit. Please note that this permit does not
affect your legal obligation to obtain other permits required by the Division of Water Quality, the Division
of Land Resources, the Coastal Area Management Act, or other federal or local governments.
If you have questions, or if we can be of further service, please contact Joe Corporon at

Permit NC0026000
A. (2) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 90 %.
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, March, June, September, and
December. 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, DWQ Form AT-3 (original) is to be sent to the
following address:
Attention: NC DENR / DWQ / Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section 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 Section 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 Division 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 than 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/or 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 initial
monitoring.
Permit NC0026000
A. (3) MERCURY REOPENER.
The Division may re -open this permit to require mercury Ioad limitations, mercury minimization plans, and/or
source water characterization following completion of the Phase II Mercury TMDL for the Lumber and
Waccamaw River watersheds.
A. (4) HEADWORKS /PUMP STATION EVALUATION — SPECIAL CONDITION
Data suggest that peak flows overwhelm the WWTP headworks. Therefore, within 90 days of the permit
effective date, the Permittee shall provide an Engineering Analysis of the WWTP headworks design (pipe -sizing,
concrete fixtures, grit chamber, and bar screen) and operation specifically addressing the impact of peak flows
routed via the influent pumping station. This report shall include findings and recommendations for additions
and/or operational adjustments.
A. (5) TERTIARY SAND FILTERS — SPECIAL CONDITION
Considering that the Permittee received an Authorization to Construct permit and a Clean Water Management
Trust Fund grant (CWMTF 1997A-117) for a tertiary deep -filter system, the Permittee shall, within 90 days of
the permit effective date, bring these existing tertiary filters online for daily operation. Failure to meet this
Special Condition will constitute a violation of this permit for "failure to properly maintain and operate" a
permitted facility, and will subject the Permittee to civil penalty assessment.
A. (6) INFLOW AND INFILTRATION STUDY — SPECIAL CONDITION
Within 30 months of the permit effective date, the Permittee shall design, fund, and implement a Sewer Collection
System Evaluation and Remediation Plan. This Plan shall present methods to evaluate stormwater inflow and
infiltration (UI), present findings, and implement studies and remediation schedules, as needed.
The Pennittee shall report to the Division on conditions and progress by means of a Quarterly Progress
Report to be submitted no later than the end of each calendar quarter, beginning with the period following the
permit effective date. Failure to meet this Special Condition will constitute a violation of this permit and will
subject the Permittee to civil penalty assessment.
Permit NC0026000
A. (7) ANNUAL PRIORITY POLLUNT ANALYSES
The Permittee shall perform effluent Priority Pollutant (PPA) scans in accordance with 40 CFR Part 136 for all
parameters listed in the attached table. The Permittee shall sample approximately annually except to provide
seasonal variation. Unless otherwise indicated, metals shall be analyzed as "total recoverable."

05Feb2010
Joe R. Corpo • 11 NPDES East
DWQ C- tr• Office received comments on the Draft Permit from the Permittee on 19Jun2010
and, a i er . scussion with Linda Willis and Kipp Glazier of the Wilmington Regional Office
(W . O) offers the following summations for this renewal:
Fecal Coliform Sampling — The Permittee requests to sample four (4) times a week —
not five (5), as proposed in the draft permit, because a Friday sample requires them to pay
for Lab results on Saturday, an additional expense. They propose to sample Monday
through Thursday providing four (4) samples per week, and collect a fifth sample only
during storm -flow conditions on Friday. DWQ agrees that this proposal is adequate for
this Grade III facility, but has defined "storm -flow conditions" as any Friday when the
influent wastewater flow rate exceeds the permitted 1.1 MGD. Moreover, the Permittee
has volunteered to collect all fecal coliform samples during peak flow between 09:00 and
14:00 hrs. The permit final will so stipulate.
• Minor Corrections to the Draft Permit — The Permittee notes that the Supplement to
Cover Sheet incorrectly lists two clarifiers operated in series noting that they are often
used in parallel. However, because plumbing provides the option to use either way, DWQ
has modified the permit final to read "(may be operated in parallel or in series)." Also,
the draft incorrectly described the chlorine disinfection system as "liquid" chlorination -
this has been corrected to read "gaseous" chlorine.
• Special Condition A. (3.) - Additional Evaluation of the WWTP Headworks — The
Permittee has questioned the need for additional evaluation of the WWTP headworks.
They argue that they paid a consultant recently to evaluate the WWTP and build the
upstream pumping station and DWQ approved this design. After additional review, the
WaRO notes that the Authorization to Construct permit for the pumping station did not
include a holistic evaluation of its affects on the existing WWTP. As observed during
DWQ's onsite inspections, the pumping station (a 3-pump system) cycles on
automatically, adding pumps in response to progressively higher flow conditions.
However, more than one pump overwhelms the WWTP headworks causing raw sewerage
to overflow and spill to the receiving -stream environment. High influent flow may only
be diverted to the new EQ basin if an operator is present to manually divert the flow.
Therefore, the Division feels strongly that this system needs a holistic reevaluation from
headworks to outfall and will continue to require permit Special Condition A. (3.) — no
changes to the permit final. This issue will be addressed in the Permit Final cover letter.

DAVID E. MINCEY
MITCHELL WARD
TRENT BURROUGHS
Thank you for your letter dated December 16`h in which you discussed the NPDES permit proposed for the
Tabor City Wastewater Treatment Plant. In that letter you gave Tabor City the chance to provide comment
and/or corrections to the draft. Thank you for that opportunity, and please consider this letter as our
comments to the materials we have received.
One of the most important issues that we would like to bring to your attention is the proposed issue
concerning Fecal Coliform testing. The Town of Tabor City understands from your draft that you wish to
have our Fecal Coliform test samples increased to five (5) times per week. This would be not feasible for us.
This would require the laboratory to do their analysis on the weekends for the Friday sample. Our Lab is not
opened on weekends. Instead, the Town of Tabor requests four (4) per week Fecal Coliform testing. These
four (4) samples would be collected during peak wastewater influent flow (between 9:00 A. M. and 2:00 P.
M.) Attached is our SOP for NPDES permit sampling. It was revised on December 1, 2009. It addresses
special Fecal Coliform sampling for abnormal rainfall and pending storm flow conditions. We look forward
to your revision of our new permit away from five (5) times per week sampling for Fecal Coliform.
The other comments that we make to the materials sent to us are less severe. For example, on the first page
of the cover letter dated December 16th, it states that the Town of Tabor City has a backup liquid chlorine
system. This is incorrect. The Town of Tabor City has always used gaseous chlorine.
In the "Supplement To Permit Cover Letter" it states that two (2) clarifiers, operated in series. This should
read "operate in parallel". The cover letter also stated that the town is being required to analyze "unsolved
overflow issues at the plant head works." We question why this data is needed at this time. Recently the
town implemented a complete renovation of the Wastewater Treatment Plant and the plans and specifications
for these improvements were approved by the engineering staff of the State of North Carolina. We are
merely operating pumps and head works improvements that have already been analyzed by your engineers.
We trust that these comments are helpful and will be an improvement to the permit that is about to be issued
to our Wastewater Treatment Plant. Should you have any questions, please feel free to contact me at your
earliest convenience.
Respectfully,

3. Treatment Plant Classification: Class III
4. Important SOC, JOC or Compliance Schedule Dates: See comments in Part III.
Part III. Evaluation and Recommendations:
1. This facility is on the EPA's Watch List for mercury violations.
RO Recommendation: The Town of Tabor City needs to determine the cause of the mercury
violations and implement a plan to eliminate all potential sources until the source has been
identified. A compliance schedule (recommend 3 months) to research and identify the source is
requested.
2. The Town received a Clean Water Management Trust Fund grant (1997A-117) for $570,000.00
to add a tertiary filtration process (deep sand beds) to the wastewater treatment system, prior to
chlorination. The Town has the filters in place but has failed to maintain the filters and they are
currently not being used.
RO Recommendation: Provide a 3 month compliance schedule requiring the Town to; (1)
refurbish the tertiary filters for daily operation and (2) build a safe access to the filters because
the access ladder is slippery and dangerous for both the operator and the inspectors. Their
operator is not physically able to climb the ladder to the tertiary filter platform. The facility now
uses UV disinfection, therefore the filters are needed to ensure better effluent quality.
3. WiRO is concerned that the influent lift station pumps overwhelm the headworks at the plant
during high flows.
RO Recommendation: The RO requests a 90-day compliance schedule for engineering analyses
of the headworks. The analyses should provide wastewater elevations through the headworks
(grit chamber and bar screen) during peak flow and when the back up pump is operating.
4. The UV disinfection unit is not capable of disinfecting the effluent during plant upsets and high
flows as a result of rain events.
RO Recommendation: DWQ is requesting a backup disinfection system be required to provide
adequate disinfection during high flow situations and upset conditions. Please include TRC
limits when back up disinfection is being used.
5. WiRO would like to resolve sampling issues at this facility via the NPDES Permit sampling
requirements. Any questions concerning this request, please contact Kipp Glazier at 910-796-
7272.
RO Recommendation: Require fecal coliform monitoring 4 times per week (regardless of
whether the tertiary filters are operable) with at least 33% of the samples taken between 9:00 AM
and 1:00 PM. Require monitoring for all parameters on any day in which an upset is occurring.
6. The ORC does not notify the Region when they are experiencing upsets, when they are
bypassing one of their two clarifiers, when they are not using their filters and when they
experience an overflow at the headworks or from their sanitary sewer collection system.
RO Recommendation: Please remind the Town in the cover letter that the standard conditions
in the NPDES Permit requires their notification to this office in the event of any of the above
situations and failure to do so is a violation of their NPDES Permit.
WiRO appreciates both the site visit by permit writer, Joe Corporon, and the opportunity to
comment. WiRO supports renewal of the permit provided the permit reissuance is in accordance
with the Lumber River Basin Plan permitting strategy and no adverse public comments are received.
We appreciate any effort to include the recommendations provided.

FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES Permit NC0026000
INTRODUCTION
Town of Tabor City Wastewater Treatment Plant (WWTP), herein called Tabor City or the Permittee,
requires a National Pollutant Discharge Elimination System (NPDES) permit to dispose treated
wastewater to the surface waters of the state. The permittee's 5-year NPDES permit expired August 31,
2009 and they have requested renewal from the Division of Water Quality (the Division). This Fact Sheet
summarizes background information and rationale used by the Division's NPDES Program to determine
permit limits and monitoring conditions.
Facility Description. The Tabor City WWTP (Table 1) is a 1.1 MGD publicly owned treatment works
(POTW) utilizing a Grade III activated sludge wastewater treatment facility to treat domestic wastewater
only (no longer services industry). The Tabor City treatment system utilizes: an influent pumping station;
Parshall flume; mechanical bar screen; mechanical grit removal; dual -train activated sludge extended -
aeration lagoons with mechanical surface aerators; one equalization basin (1.7 MGD); dual clarifiers
operated in series; four each, Waterlink Super deep -sand filters (currently bypassed); UV disinfection
with back-up gas chlorine / sulfur -dioxide feed system; chlorine contact basin; aerated sludge -holding
basin; effluent sampler; ultrasonic flow meter; and a back-up power generator.

FACILITY RECORDS REVIEW
Waste Load Allocation (WLA). The Division prepared the last WLA for the receiving stream in June
1994 and developed effluent limits and monitoring requirements considering an in -stream waste
concentration (IWC) of 90 % at 1.1 MGD, considering zero -flow stream conditions. The Division views
these limits and monitoring requirements appropriate for renewal except as outlined below (see
Permitting Approach Summary).
Verifying Existing Stream Conditions. This facility discharges under zero -flow stream conditions to
an unnamed tributary of Grissett Swamp [Stream Index No. 15- 17-1-(5)], a Class C Swamp waterbody
located within the Lumber River Basin. While not formally listed as "impaired" [not on the Division
303(d) list], Grissett Swamp contributes as one of 11 drainages within the Lumber River Basin with fish
advisories for mercury
Pretreatment. During the previous permit cycle, the Division reviewed Tabor City's need to implement
a Long Term Management Plan (LTMP) or pretreatment program. The Permittee currently has no
significant industrial users (see NPDES Application, Form 2A) and has yet to develop an LTMP.
Authorization to Construct (ATC). In March of 2007, the Permittee received an ATC permit
(NC0026000AO 1) to install modifications and new components summarized as:
• lined flow -equalization basin (1.4 MGD HDPE);
• new pumps (influent pump station immediately upstream of the headworks);
• two (2) new aeration basins (with new aerators); demo the old basins;
• new deep -sand tertiary filter system
• new UV disinfection system, and
• new sludge -loading station
The Division received notice on August 20, 2008 that the above work was completed (DWQ's Engineer's
Certification Form signed August 15, 2008 by Bill Lester Jr., P.E.).
Compliance. Tabor City is currently on EPA's Watch List for mercury violations. The Permittee also
received EPA's Administrative Order CWA-04-2010-4751 (308/309 letter) dated October 15, 2009
based on a "show cause" meeting held January 7, 2009 to discus permit violations. Tabor City's
compliance history shows "significant non-compliance" for the last half of 2007 and the first half of 2008.
Violations include multiple permit limit violations for mercury; limit exceedences for ammonia nitrogen
(NH3 as N) Weekly and Monthly Averages; violations for Total Residual Chlorine Daily Maximum; and
violations of BOD 5-day Monthly Average limits.
This administrative order (AO) required the Permittee to submit a Mercury Minimization Plan for
approval and conduct mercury sampling, analysis of the aeration chamber Mixed Liquor Suspended
Solids (MLSS), and reporting — preliminary sampling to commence no later than seven (7) days from
date the AO was received by the Permittee. Finally, the AO requires compliance to the NPDES permit by
July 31, 2010.

Correspondence and Site Visits
Renewal Application and Attachments. The current permit expired on August 31, 2009, and the
Division received the Permittee's timely request for permit renewal (Standard Form 2A) on January 26,
2009 through its consultant, Hobbs, Upchurch & Associates, P.A. The application included the required
additional Priority Pollutant Analysis (PPA) data for 2005, 2007 and 2008 (no parameters detected), and
the three each second -species Whole Effluent Toxicity (WET) tests (030ct08, 23Jun08, and 28Ju108).
Site Visit / Staff Report — Wilmington Regional Office (WiRO). Linda Willis (WiRO), Joe Corporon
and Bob Guerra of DWQ's Central Office, conducted a facility inspection on August 5, 2009. At the time
of this inspection, the "Interim" ORC reported that Tabor City was having difficulty securing and
retaining adequately trained personnel (ORC and backup ORC) to effectively operate this facility. She
volunteered that she needs assistance to adjust system operations (to lift greats and manhole covers, to
turn valves and divert flow; to access sand filters; and to clean bar screens). WiRO recommends permit
renew in accordance with the basin plan, but notes the following specific issues, potentially to be
addressed by permit Special Condition:
Influent Pump Station — Upon inspection, Staff found the influent pump station (immediately upstream
from the headworks) "in alarm." The Operator in Responsible Charge (ORC) called the city's "pump
man" because the pump station was not included in her responsibilities. The "pump man" verified that at
high flow, the pump -system switch configuration will not run on AUTO without overflowing the WWTP
plant headworks (designed and installed by Hobbs -Upchurch). Therefore during periods of high influent
(almost anytime it rains), the pump -station operator must remain onsite to manually divert flow. He
volunteered that for 6 days previous to the site visit, he remained onsite to manually divert second- or
third -pump flow to the EQ basin due to daily thunder storms. For recommended solutions to this problem,
see Renewal Summary — Permit Special Conditions.
Headworks —Inspection of the headworks showed signs of raw sewage overflow, unreported. Staff took
photos of water -erosion trails leading downhill from flush -mounted concrete boxes suggesting loss of
untreated sewage to the environment. Influent piping to the headworks and terminating concrete
structures appear undersized, too small to handle the influent pump -station if more than one of three
available pumps operates at the same time. For recommended solutions to this problem, see Renewal
Summary — Permit Special Conditions.
UV System Disinfection — Installed in the chlorine -contact chamber (Hobbs -Upchurch), the UV
disinfection system floods from upstream, if forced by headworks over -pumping. High rainfall backing
up from the river may also flood the disinfection system. Past flood events have shorted out the UV
system requiring replacement of both bulbs and electronics. Repair efforts have included raising the walls
of the chlorine -contact chamber by two cinder blocks (-16 inches). As repaired however, the UV system
still does not adequately disinfect, and the Permittee has resorted to backup chlorination in order to meet
fecal coliform limits. The Division suspects that UV disinfection has been rendered effective either, by
deepening the trough under the UV bulbs (reducing UV penetration), and/or by inadequate tertiary
filtration. For permitting recommendations, see Renewal Summary — Permit Special Conditions.
New Sand -Filter System — During the previous permit cycle, the Permittee installed a new multi -story
tertiary deep -sand filter system specifically invested to produce effluent suitable for UV disinfection.
However, do to this lack of routine maintenance this treatment component is currently bypassed resulting
in wastewater inadequately treated for final UV disinfection. Consequently, the Permittee has resorted to
back-up disinfection using chlorine. For recommendations, see Renewal Summary — Permit Special
Conditions.

PERMIT RENEWAL APPROACH
DMR Instream and Effluent Flow Data Review. The Division reviewed 30 months of DMRs
(January 2007 through July 2007) noting annual flow averages of 0.490 MGD (2007), 0.355 MGD
(2008), 0.377 MGD (2009). These flows together average 0.407 MGD or about 37% of permitted
capacity over this time period.
Whole Effluent Toxicity (WET) Testing. The Division reviewed Tabor City's quarterly WET test
records from January 2005 through March 2009 (17 quarterly tests and 4 monthly follow-up tests). Tabor
City failed its WET test in September of 2005 and 2006, and again in December 2007 — each episode
followed by monthly testing. In each case toxicity was resolved after the second monthly test. No
violations have been reported since December 2007.
Toxicant Chronic and Acute Impact — Pollutants of Concern (POCs). To establish POCs, the Division
reviewed the permit application, discharge monitoring reports (Jan 2007 through July 2009), and the Basin
Plan. The Division then used the standard Reasonable Potential Analysis (RPA) to calculate a maximum
predicted concentration for each POC, copper, mercury and zinc. Each maximum was then compared to the
POC's freshwater Chronic Standard (Table 2) and also to its Final Acute Value (%2 FAV) for freshwater
(Table 3).
If by the above method, a POC showed reasonable potential to exceed its %2 FAV, the Division inserted a
permit limit as a Daily Maximum to protect the receiving stream against acute toxic affects. Similarly, if the
maximum exceeded the chronic standard, a Weekly Average limit was added to the permit.

RENEWAL SUMMARY
Receiving -Stream Monitoring No changes recommended.
Effluent Monitoring For Renewal:
Because the Permittee may need backup disinfection, the Division has retained the TRC
limit and included the following footnote:
"Total Residual Chlorine (TRC) shall be monitored only if chlorine is used to disinfect.
Because of difficulties quantifying TRC in a wastewater matrix, the Division will consider
all TRC values reported below 50 µg/L to be compliant with this permit."
Additional Requirements and Special Conditions.
Disinfection
Mercury
Headworks
Tertiary Sand Filters
Sewer Collection System
Data suggest the UV disinfection system is not viable during plant upsets
or during high rain events. In such cases the Permittee must
revert to chlorination and dechlorination. Therefore, compliance
to a Total Residual Chlorine limit will remain in the permit.
Mercury limits remain in the permit; A Mercury Minimization Plan is in
progress addressing source evaluation, sampling, reporting, and
final compliance with the permit (EPA's Administrative Order
CWA-04-2010-4751); no additional action required.
Data suggest that peak flows overwhelm the WWTP headworks. The
permit cover letter shall remind the Permittee that failure to
report a sanitary sewer overflow is a permit violation liable to
penalty assessment. Furthermore, within 90 days of the permit
effective date, the Permittee shall provide an Engineering
Analysis of the WWTP headworks design (pipe -sizing, concrete
fixtures, grit chamber, and bar screen); headworks operation
shall specifically address the impact of peak flows routed via the
influent pumping station. This report shall include findings and
recommendations for hardware mediation and/or operational
adjustments [see Special Condition A. (4.)].
The Permittee shall refurbish the tertiary deep -sand filters, providing
regular, routine inspection and maintenance, and bring filters
online for continuous operation within 90 days of the Permit
effective date [see Special Condition A. (5.)]. Failure to meet
this deadline is permit violation liable to penalty assessment.
DWQ has correlated storm events with inordinately high flow at the
WWTP suggesting that this facility suffers from stormwater
inflow and infiltration (1/1). Therefore the Division has added a
Special Condition requiring a Collection System Evaluation and
Remediation Plan to fund, study, and implement remediation.
This plan requires progress reports to the Division before the end
of each calendar quarter, and remediation to be completed within
thirty (30) months of the permit effective date [see Special
Condition A. (5.)].

NPDES Permit NC0026000

Increased Sampling
WiRO has documented fecal coliform effluent concentrations in
violation of the permit limits despite self -monitoring indicating
"pass" at the current frequency. DWQ shall therefore increase
the monitoring frequency for Fecal Coliform from 3/Week to
1/Day [see A. (1.)] requiring a minimum of three (3) samples
collected during peak influent flow (9:00 hrs — 14:00 hrs). This
Special Condition shall continue for six (6) months from the
permit effective date, after which time the Permittee may petition
DWQ to alter the monitoring conditions, as data warrants.
