Subject: Issuance of NPDES Permit No. NC0081370
Claremont — McLin Creek WWTP
B&B Road (SR 1728)
Catawba County
Dear Ms. Bumgarner:
The Division of Water Quality (the Division) hereby issues this final permit for the subject facility.
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 May 9, 1994, or as subsequently amended.
Grade II verses Grade III. Previous permits for this facility, including the proposed draft permit,
reflect a Grade III WWTP classification. While the as -built treatment system includes tertiary filters,
the Division understands that discharge conditions do not warrant nutrient removal, i.e., Total
Nitrogen and Total Phosphorus permit limits do not appear in the permit.
The Division has therefore reclassified the subject WWTP from Grade III to Grade II, considering
permitted flow less than 0.500 MGD. Correspondingly, monitoring frequencies for this final issuance
have been relaxed from 3/Week to Weekly for many effluent parameters and also for receiving -stream
monitoring, as appropriate for Grade II treatment works.
Concerning Mercury. Per your request, the Division has revisited mercury data. The Division
notes that and feels that the mercury concentration reported as 2.7 ug/L or 2,700 ng/L (November
2004) constitutes a statistical outlier. We feel this data point does not accurately represent site
conditions. Without this outlier, mercury data suggest no reasonable potential to exceed the water -
quality standard. Therefore, the mercury limit included in the draft permit has been removed, and
this final issuance reflects mercury monitoring only — no permit limit.
Concerning Total Residual Chlorine (TRC). Since your last permit renewal; the Division has adopted
a stream standard for chlorine. The Division has therefore added a TRC limit of 28 µg/L to your permit,
in keeping with other NPDES permits statewide. Please note that you may need to acquire additional
instrumentation, equipment, and/or services adequate to monitor and control chlorine at this

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 notice 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.

SUPPLEMENT OT EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
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, 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 Branch
North Carolina Division of
Water Quality
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch 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 Branch 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.

Mercury — After revisiting mercury data, the Division decided that the
November 2004 hit (reported as 2.7 ug/L = 2,700 ng/L) does not represent
actual site conditions. It is out best professional judgment (BPJ) that this
report is a data outlier.
Considering test method EPA 1631 data, the new maximum predicted is
0.1196 ug/L while the maximum allowable is 0.1410 ug/L. Therefore, mercury
data show no reasonable potential to exceed the water -quality standard, and
the mercury limit placed in the draft permit has been removed prior to
issuance.
Treatment Plant Grade II verses Grade III. Previous permits for this facility
(including the renewal draft) reflect a Grade III classification. The Division drafted
this permit as a Grade III WWTP based on Grade II flow plus the inclusion of tertiary
filters in the treatment system. However, the Permittee does not have Total Nitrogen
and Total Phosphorus limits in the permit, and therefore is not required to remove
nutrients.
The Division has therefore reclassified this facility from Grade III to Grade II.
Correspondingly, monitoring frequencies for this final issuance reflect Weekly
monitoring for many effluent parameters. Receiving -steam monitoring has likewise
been relaxed to Weekly, as appropriate for Grade II treatment works. A note has been
added to the final permit issuance cover letter.

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. This document also contains references to information sources relevant
to this permit renewal.
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 <0.500 MGD, this facility is Class III (nutrient reduction processes required). Influent from a
single Significant Industrial User (SIU) represents <1 % (0.001 MGD) of the total discharge.

CORRESPONDENCE
Staff Report. Fayetteville Regional Office (FRO) conducted an annual facility inspection and Samar
Bou-Ghazale, P.E., prepared a Staff Report dated May 6, 2005. The FRO staff found the facility in
good condition and in compliance with the permit, recommending that the NPDES Program renew
the permit in accordance with the basin plan.
The Division contacted the Permittee August 30, 2005 to correct the effluent database and the
Permittee complied on August 31, 2005 (see RPA concerning mercury).
COMPLIANCE REVIEW
Division Records and Permittee's Renewal Application. McLin Creek WWTP began operation
officially with its first permit effective on June 26, 1995. This last permit expired on July 31, 2005
and the Division received prompt documentation to renew (Short Form A) on January 31, 2005.
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 [11-76-5-(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 27 months of DMRs (January 2002 through March 2005). The Division compiled
27 consecutive monthly flow averages for an overall average of 0.167 MGD, noting that effluent
flows approximate 56% of permitted capacity.
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. No changes recommended.
Whole Effluent Toxicity (WET) Testing. The Division reviewed quarterly Whole Effluent Toxicity
records from January 2001 through April 2005 (14 quarterly tests). The Permittee passed all quarterly
toxicity tests.
Notices of Violation (NOVs) and Penalty Assessment. The Division examined compliance records
from January 2003 through July 2005. This facility received no violation assessments, and during this
time period was sited for three "missing signature" violations only.

Pretreatment Compliance. This NPDES permit requires the permittee to implement 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. The Permittee's LTMP (modified with a
Short Term Management Plan (STMP) has been approved by the Division and related influent
parameters were considered during the Reasonable Potential Analysis. Claremont McLin Creek
currently services only one Significant Industrial User (SIU) with a permitted influent totaling <1,000
GPD (<1 %) of the permitted discharge.
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),
pretreatment data, and the Basin Plan. The Division then used the 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 also to its Final Acute Value ('/z 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).

** Mercury database includes both Methods EPA 245.1 and EPA 1631 (14 sample events) because both
analytical methods detected mercury. The receiving stream is not "impaired" for mercury [not 303d listed],
therefore the permit limit considers dilution by the receiving stream.

Thanks for keeping me in the loop! The Fact Sheet says one SIU of <1,000 gpd77992979 My records
show the WWTP has 2 SIUs that are are permitted to discharge a combined total flow of 0.102 MGD.
These are Pierre Foods at 0.027 MGD and Draka Comteq - 0.075 MGD. Draka might not have been
reflected in the POTW's application as they are new (replaced Alcatel from several years ago). But if
the application really says that Pierre is <1,000 gpd, let me know!
