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 9 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase II
Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed
during the months of January, April, July, and October. Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then
multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North
Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
.The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no
detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction
or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the `North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent
versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1)
for the months in which tests were performed. 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 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 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.

FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES Permit NC0081370
INTRODUCTION
City of Claremont / McLin Creek WWTP (also herein referred to as the Permittee or McLin Creek)
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 has expired 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 Unit to determine
permit limits and conditions.
FACILITY RECORDS REVIEW
Facility Description. McLin Creek WWTP (Table 1) is a 0.300 MGD Publicly Owned Treatment
Works (POTW) utilizing a parallel dual -train activated sludge wastewater treatment system consisting
of a 0.040 MGD train and a 0.060 MGD train, both discharging through Outfall 001. Although flow
is permitted < 0.500 MGD, this facility is Class III (nutrient reduction processes required). McLin
Creek WWTP has no Significant Industrial Users (SIUs).

CORRESPONDENCE
Staff Report. Mooresville Regional Office (MRO) conducted an annual facility inspection and
generated a Staff Report dated November 16, 2009. B. Dee Browder, Engineer (MRO) recommends
that the NPDES Program renew the permit in accordance with the basin plan. They also note that the
City of Claremont has transferred the operation and management of the McLin WWTP by agreement
to City of Hickory, and Hickory began operating the plant in July 2009. This is confirmed by the
Permittee's renewal application.
Intent to Connect to Regional System. Claremont has applied to the Clean Water Management
Trust Fund for financial aid to connect both the McLin Creek WWTP and the Claremont North
WWTP to the regional Hickory WWTP. If funded, this financial aid will cover an estimated 80% of
project costs. Upon connection, Claremont intends to request rescission of both these permits
(NC0081370 and NC0032662).
COMPLIANCE REVIEW
Division Records and Permittee's Renewal Application. McLin Creek WWTP began operation on
June 26, 1995. This last permit expired on July 31, 2010 and the Division received prompt
documentation to renew (Form 2A) on October 1, 2009.
Waste Load Allocation (WLA). The Division prepared the last WLA in January 1995 and
developed effluent limits and monitoring considering an in -stream waste concentration (IWC) of 9 %.
The Division judges these limits and monitoring requirements to be appropriate for this renewal with
the exception of the additions and deletions listed below (see PERMITTING APPROACH SUMMARY).
Verifying Existing Stream Conditions. This facility discharges to McLin Creek I11-76-5-(0.3)], a
Class C stream within the Catawba River Basin. McLin Creek is not listed as an "impaired"
waterbody [not 303(d) listed].
DMR In -stream and Effluent Data Review. DMRs appear regular, thorough, and complete. The
Division reviewed 58 months of DMRs (January 2006 through October 2010). The Division compiled
flow averages for 2006 (0.151 MGD) and 2010 (0.164 MGD), noting that effluent flows consistently
approximate 55% of permitted capacity over the previous permit cycle.
Effluent Total Residual Chlorine (TRC). The permittee currently chlorinates and de -chlorinates its
effluent restricted by a Weekly Average TRC limit of 28 µg/L. A footnote has been added to the
effluent page providing compliance for all values reported below 50 ug/L, in accord with the
statewide policy for TRC.
Whole Effluent Toxicity (WET) Testing. The Division reviewed quarterly Whole Effluent Toxicity
records from January 2006 through July 2010 (19 quarterly tests). The Permittee passed all quarterly
toxicity tests (see attached documentation).
Notices of Violation (NOVs) and Penalty Assessment. The Division examined compliance records
from January 2006 through July 2010. This facility received more than several violations and civil
penalty assessments for BODS, ammonia nitrogen and fecal coliform (see attached compliance and
enforcement report sorted by year).
Fact Sheet 2011
Renewal -- NPDES NC0081370
Page 2

Pretreatment Compliance. Claremont McLin Creek currently services no Significant Industrial
Users (SIUs). Therefore, as of this renewal this NPDES permit does not require a Long
Term Management Plan (LTMP) or pretreatment program as specified by federal regulations 40 CFR
403 and Title 15A NCAC 2H.0900 of state regulations.
Toxicant Chronic and Acute Impact — Pollutants of Concern (POCs). To establish POCs, the
Division reviewed the permit application, discharge monitoring reports (Jan 2002 through July 2005) and
the Basin Plan. The Division used EPA's standard Reasonable Potential Analysis (RPA) to calculate a
maximum predicted concentration for each POC. Each maximum was then compared to the POC's
freshwater Chronic Standard (Table 2) and to the Final Acute Value (Y2 FAV) for freshwater (Table 3).
If by the above method, a POC showed reasonable potential to exceed its %2 FAV, the Division included 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. Findings
are summarized below (see Renewal Summary, Table 4). POCs for this renewal include the metals
copper, mercury, silver, and zinc.

PART IV - EVALUATION AND RECOMMENDATIONS
The permittee, has requested reissuance of the subject permit.
The MRO is becoming aware of more contract operations associated with both collection
systems and receiving WWTPs. Claremont has entered into a contract with the City of Hickory to
operate the WWTP. Because of the increasing number of NPDES Permits and the variety of
scenarios that MRO sees associated with agreements, contracts, or other methods of negotiation of
operation of these facilities we recommend that the contract operations entity be named in some
portion or attached document associated with the permit evaluated and that official notice be
required if this contract becomes nonviable for any reason.
It is recommended that the permit be renewed, pending a final review and concurrence of the
draft permit when it becomes avy

Sludge Management Practices - Composting ID # WQ0004563
City of Claremont McLin Creek WWTP
Claremont, North Carolina
Dear Ms. Sprinkle:
The City of Clarmeont's McLin Creek Wastewater Treatment Plant processes all of its
sludge by composting. Sludge is removed from the aeration basins and placed in a
digester to reduce the amount of volatile solids and to allow the sludge to thicken.
Supernate is decanted and returned to the head of the plant. The thickened solids are
taken to the Hickory Regional Compost Facility in Newton, NC, for further processing
into compost material. During the composting process, the sludge is stabilized
sufficiently to meet all vector attraction and pathogen reduction requirements. Once
dry, the cured compost is distributed to various entities to be used as a soil amendment.
If additional information is needed, please feel free to contact me at [phone].
