Dear Mr. Peeler:
The Division of Water Quality (Division) personnel have reviewed and approved your request for permit modification,
to include the following changes:
• Interim effluent sheets for 3.5 MGD and 4.5 MGD have been added, in addition to the original permit for 6.0
MGD. The interim effluent sheets provide for total antimony effluent limits of 85.0 ug/1 at 3.5 MGD and 67.4
ug/1 at 4.5 MGD, which are based on a 7Q10 flow of 77 cfs and a water quality criterion of 5.6 ug/l for water
supply waters. All other permit conditions remain unchanged.
• A new Special Condition A(8)- Annual Flow Reporting- has been added to require reporting of annual average
flow data, and contacting the Division of Water Quality upon transition to the next phased effluent sheet.
Transition will be required upon annual average flows exceeding 90% of permitted flow.
This permit modification will become effective on December 1, 2012.
This permit modification 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. If any parts, measurement frequencies, or sampling requirements contained in this
permit modification are unacceptable, you have the right to an adjudicatory hearing upon written request 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 must be filed with the Office of Administrative Hearings, 6714 Mail Service
Center, Raleigh, North Carolina 27699-6714. Unless such demand is made, this permit remains final and binding.

Permit No. NC0025496
SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (4). COLOR MONITORING REQUIREMENT
The permittee will conduct color monitoring of instream stations (upstream, downstream) on a monthly basis
during summer season (April -October). Effluent samples will be collected monthly for color on a year-round
basis. Color samples will be analyzed for ADMI color at natural pH. Effluent samples will consist of 24-
hour composites, while instream samples will be collected as grabs. Samples will be analyzed by a state
certified laboratory.
If data show that water quality standards for color are being violated by the discharge permitted by the terms
of this permit, then the Director may reopen this permit for the purpose of imposing additional requirements
pursuant to 15A NCAC 2H.0114. Alternatively, if future conditions change and color is no longer a
component of the influent wastestream, then the permittee may request a permit modification to remove color
monitoring requirements.
A. (5). 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 11 %.
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: Environmental Sciences Section
North Carolina Division of
Water Quality
1621 Mail Service Center
Raleigh, North Carolina 27699-1621

Permit No. NC0025496
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.
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 (6.) EFFLUENT POLLUTANT SCAN
The Permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed below. One
scan must be performed in each of the following years: 2012, 2013, and 2014. Analytical methods shall be in
accordance with 40 CFR Part 136 and shall be sufficiently sensitive to determine whether parameters are present
in concentrations greater than applicable standards and criteria. Samples should be collected with one quarterly
toxicity test each year, and must represent seasonal variation [i.e., do not sample in the same quarter every year].
Unless otherwise indicated, metals shall be analyzed as "total recoverable."

Subject: RE: NC0025496- Proposed Mod
Karrie-Jo: this permit was issued just 6 months ago, so I don't plan to redo RPA for this simple mod request (interim flow
sheets). Regarding mercury, we don't have an EPA -approved mercury TMDL yet as far as I'm aware, and Jeff mentioned
that once TMDL is approved, we would have some stakeholder involvement before proceeding forward with any new
MMP requirement. Thus I don't want to sit on this mod request pending mercury issues to play out down the road.

Subject: Re: NC0025496- Proposed Mod
Since this is a modification, I think you should also include the recommendations in r to include a
mercury minimization plan and to include an RP analysis based on background conce . If the facility
does not yet have any background data, then I suggest you assume there is no assimilative capacity when calculating a

Facility is currently permitted at 6 MGD. Facility requested permit modification to
incorporate interim flow sheets of 3.5 MGD and 4.5 MGD, with antimony limits applicable to
those flows. Utilizing mass balance approach with 7Q10 dilution and antimony water quality
criterion of 5.6 ug/1 (Water supply), an antimony limit of 85.0 ug/1 (at 3.5 MGD) and 67.4
MGD (at 4.5 MGD) were calculated as follows:
WQS x Dilution Factor (based on 7Q10 flow) = WQBEL limit
5.6 ug/I x 15.19 = 85.0 ug/1 (at 3.5 MGD design flow)
5.6 ug/1 x 12.04 = 67.4 ug/1 (at 4.5 MGD desin flow)
No other changes to permit limits/monitoring are proposed. A Special Condition A(8)-
Annual Flow Reporting- has been added to trigger reporting/notification by Permittee.
Transition to next phased effluent sheet is based on reaching 90% of permitted flow.

The City of Lincolnton requests a minor amendment of our NPDES Permit for
antimony. The WWTP currently has a discharge limit for antimony of 52ug/I at
6 mgd. The City would like to amend our existing Permit to have a tier discharge
limit at 3.5 mgd, 4.0 mgd, 5.0 mgd, and retain the current limit for antimony of 52
ug/I at 6 mgd.
We trust this meets with your approval. If there are questions, please do not
hesitate to call. Thanks for your assistance.
Sincerely,
Stephen H. Peeler, Director
Public Works & Utilities
