Subject: Issuance of Renewal Permit.
NPDES Permit NC0086550
Town of Fairmont WWTP
Class III
Robeson County
Dear Mr. Proctor:
Dee Freeman
Secretary
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 the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as
subsequently amended).
With the Lumber River being impaired for mercury, the EPA did not support the proposed draft
permit mercury monitoring removal and mercury compliance limits assessment. As an alternative, EPA
proposed provisional limits with the option for the permittee to petition for re-evaluation after obtaining 12
data points. This provisional condition allows for changes to mercury monitoring and limits without opening
the permit. Consequently, mercury monitoring, effluent and upstream, with a provisional condition was
added to the final permit. Be aware the permittee is required to petition the Division to initiate the re-
evaluation process, and must submit his request no later than August 1, 2011 after 12 consecutive
monthly mercury data points have been obtained.
Summary of Changes in Renewal Permit from Existing Permit
1) Mercury monitoring and limits have been revised with the addition of provisional conditions. To
comply with EPA criteria and to allow the permittee to petition for re-evaluation, mercury
monitoring was increased to monthly pending re-evaluation. After 24 months from the effective
date of the permit if the applicable limits are not removed they become effective. If the limits
are removed then mercury monitoring can be reduced to quarterly.
2) instream monitoring Special Condition has been revised to remove instream monitoring, except
for mercury, with reopener conditions. With no stream impairment other than mercury, lack of
effective downstream sample locations, and the availability of existing ambient monitoring
stations justify no instream monitoring at this time. The Division can require future instream
monitoring without reopening the permit.

Footnotes:
1. The monthly average effluent BOD5 and Total Suspended Solids concentrations shall not exceed 15
percent of the respective monthly average influent value (85% removal).
2. Total Residual Chlorine compliance is required for chlorine or chlorine derivative used for
disinfection. The Division shall consider all effluent TRC values reported below 50 ug/L to be in
compliance with the permit. However, the Permittee shall continue to record and submit all values
reported by a North Carolina certified laboratory (including field certified), even if these values fall
below 50 ug/L.
3. Total Mercury compliance limits are provisional as defined in special condition A. (5.). If prior to
November 1, 2011 the Division has not removed the imposed limits then the compliance limits
become effective November 1, 2011.
4. Upstream = boat ramp/public access US Highway 74.
5. Chronic Toxicity (Ceriodaphnia ) P/F at 2.2%; February, May, August, and November. See Special
Condition A.(2.) of this permit. Quarterly sampling shall be conducted at the same time as metal and
other effluent parameters sampling is conducted.
'6. See Condition A.(3.) of this permit.
There shall be no discharge of floating solids or visible foam in other than trace amounts.
Permit NC0086550
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 2.2 %.
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 February, May, August, and November.. 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 11 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 pad of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed. If reporting
pass/fail results using the parameter code TGP3B, DWQ Form AT-1 (original) is sent to the below
address. If reporting Chronic Value results using the parameter code THP3B, 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 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.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of
such monitoring shall be included in the calculation and reporting of the data submitted on the
DMR and all AT Forms submitted.
NOTE: Failure toachieve 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. (4.) INSTREAM MONITORING REOEPNER'
At the discretion of DWQ and in the event that either:
1. This segment of the Lumber River becomes impaired for a pollutant, known or suspected
to be present in the effluent discharge, or
2. There is an impact to the Lumber River Basin requiring data to define the impact, or
3. There are changes in the State Lumber River Ambient Monitoring programs at Broadman
and Fair Bluff, then
instream monitoring can be imposed without reopening the permit. Locations, sampling
frequency, pollutants, and any other conditions will be reviewed with the permittee.
A. (5.) CONDITIONAL MONITORING FOR MERCURY
After the first 12 consecutive monitoring data values have been submitted on DMRs, the Permittee
can petition the Division to (1) re-evaluate the mercury chronic compliance limits, (2) determine
the reasonable potential for the effluent to exceed the applicable mercury compliance limits, and
if no reasonable potential is shown (3) remove the limit and reduce the measurement frequency to
quarterly. If the Permittee petitions the Division and a new compliance limit is determined then the
new compliance limit will be applied in the permit. These modifications can be done by letter from
the Division without having to reopen the permit. Provisional Limits for. Mercury take effect 24
months from the effective date of this permit if not removed.

BACKGROUND
The Town of Fairmont operates a regional 1.75 MGD wastewater treatment facility that
serves a potential population of 5,100. Several separate community collection systems
discharge into this system. In August 2008 Fairmont received approval for a pretreatment
program for one industrial source, Hager, Inc requiring 5% of the facility treatment capacity.
Hager, Inc. is covered under 40 CFR 468 and will require pretreatment monitoring of
chromium, copper, lead, nickel, zinc, and oil and grease.
Discharge from the industry did not begin until March 2009, has not been a consistent flow
source, and was not part of any data evaluation conducted because of no availability of data.
The Fairmont WWTP discharges treated wastewater to Lumber River, a class C, Swamp
water in the Lumber River Basin
Untreated domestic waste is introduced to the plant headworks via a common line from
several offsite pump stations. The influent flow is screened through a mechanical bar
screen, passes through the influent meter flume, and through a grit removal system. The
influent composite sample is collected adjacent to the influent meter flume.
The wastewater then enters a rapid mix channel, mixed with recycled sludge, and flows into
two (2) parallel aeration basin with influent gates to control the incoming flow to each basin.
Several blowers provide the air for the basins. From the basins the flows combine and then
flow into two (2) parallel clarifiers with influent gates to control the incoming flow to each
clarifier. Each clarifier discharges into its own chlorine contact chamber where chlorination
followed by dechlorination is applied. The treated wastewater exist each chamber through a
metering weir. Both weirs have totalizer that are added together to calculate the effluent
flow reported on the DMR.
The two treated wastewater stream combine and flow down a cascade post aeration flume.
An effluent composite sampler collects samples at the bottom of the cascade flume. From
the flume the treated wastewater flows to a collection sump where controlled effluent
pump(s) feed a 12 inch pressured line that discharges into the Lumber River. The discharge
point is submerged below the river water level.
€ act Sheet
NPDES NC0086550
Page Iof4
Sludge is wasted to the gravity thickener which diverts the solids to two (2) aerobic
digesters. From the digesters the sludge can either be sent to two (2) sludge holding tanks
or pumped directly to the sludge loadout station. Sludge can also be pumped from the
holding tanks to the loadout station. A contract service is used to dispose of the sludge. The
contacted service may further dewater the sludge on site, recycling the waste water back to
the facility.
HISTORY
There were no significant compliance violations or concerns during the current permit cycle
other than more recent pretreatment program documentation issues.
The Lumber River is impaired for mercury and a TMDL was performed in 2000. A revised
TMDL is pending. The current permit utilizes a reopener condition to address mercury
issues.
It was noted that the downstream sample location had been moved to the closest available
access point which was 9.7 miles downstream from the outfall. The upstream sample point
had been moved to a safer, more accessible location, adjacent to the permit designated
location.
PERMITTING STRATEGY
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 February 2007 to
January 2009 and from the 3 PPA submitted with the renewal application. Evaluations were
conducted for arsenic, beryllium, cadmium, chromium, copper, cyanide, lead, mercury,
nickel, total phenols, selenium, silver, and zinc. All of this data was collected prior to the
introduction of any industrial influent source.
Results suggest reasonable potent/a/ for the facility to discharge copper and zinc above
water quality standards (WQS). Only three silver readings were available, all below the
measurement detection limit, < 10 pg/L. All three metals are action level parameters. All
chronic toxicity tests to date were passed. Quarterly monitoring of copper and zinc will
continue.
Mercury data using IWC suggest reasonable potent/al for the facility not to discharge in
excess of the WQS. However, EPA has stated with mercury impairment of the receiving
stream the discharge chronic mercury WQS limits have to be based on no /WC being
available. When the /WC is removed then the reasonable potential for the not to discharge
Mercury monitoring will be removed to exceed the WQS is shown. To meet EPA
recommendations a provisional mercury limit with 24 month activation after the effective
date of the permit will be imposed. To assist in evaluating future mercury limits, upstream
mercury monitoring was added and is part of the provisional mercury condition. Additional
Future mercury impacts will be evaluated using the required PPA data. The Test Method
1631E is required.
An additional calculation to determine the impact of the industrial source on the RPA for
chromium, copper, lead, and zinc were conducted. For chromium, lead, and nickel excess
WQS capacities are available and should provide significant load capacities for the new
industrial source. The PERS will require quarterly monitoring of these metals plus others and
can be used in future RPA evaluations.
Data review
DMRs were reviewed for theperiod of February 2007 to January 2009. No industrial influent
was received during this period. DMR data is summarized in Table I:

Whole Effluent Toxicity
The permit requires quarterly chronic toxicity testing as a limit using ceriodapbnia dubia, at
2.2% effluent concentration. The facility has passed all its toxicity tests submitted to date.
The second species chronic tests submitted with the application resulted in a ChV value of >
8.8 %. Will continue quarterly chronic toxicity testing as a limit.
Priority Pollutant Analysis
The results of 3 PPA were submitted with the permit renewal application. See RPA Analysis
for results. Will continue to require submittal of PPA annually. Add as item on the effluent
page.
Instream Sample Locations and Data Impact
Temperature, Dissolved Oxygen, and Fecal Coliform are measured routinely at designated
points located on the Lumber River upstream and downstream from the discharge. The
downstream point was relocated to a point .9.7 miles downstream from the discharge
because of accessibility issues. The upstream point was relocated several hundred feet
further upstream to a more accessible location. The February 2007 through January 2009
data was reviewed and as suspected no impact was noted.
The possibility of moving the downstream point to a location Tess than 2 miles from the
discharge was discussed with the permittee and the region but no alternative was available.
Additional discussions with the ambient monitoring unit were conducted to determine the
significance of the data. Currently there is ambient monitoring on the Lumber River in the
same location as the Fairmont WWTP upstream and 18 miles downstream. There are no
other permitted discharges in this segment of the Lumber River.
As long as the ambient monitoring stations are maintained, and this river segment is not
impaired for any parameter that is discharged by Fairmont WWTP, instream monitoring is
removed. A reopener condition will be added. Currently, mercury monitoring at the
upstream location is required and is part of the mercury provisional condition.
Effluent Limitations and Monitoring Requirements
Flow, BOD, TSS, fecal coliform, pH, ammonia as nitrogen, DO, TRC, 85% removal of TSS and
BOD compliance limits and monitoring will continue in this permit.
To stay in compliance with Division standards the quarterly chronic toxicity monitoring/limit
will continue in the permit.
Effluent Monitoring Requirements
Copper and zinc are action level parameter and will continue to be monitored in this permit.
Mercury RPA indicates no impact of mercury on WQS. Mercury monitoring will be removed
from thispermit conducted based on the mercury provisional condition.
