Subject: FINAL -- NPDES Permit No. NC0032662
Claremont North WWTP

Catawba County
Dear Mr. McGinnis:
Responding to your renewal request, received January 4, 2000, the Division of Water Quality
(the Division) hereby transmits your final NPDES Permit.
As part of renewal, the Division conducted EPA -recommended statistical analyses on this
facility's effluent data to determine the "reasonable potential" for identified metals to exceed North
Carolina Water Quality Stream Standards. These and other analyses have prompted the following
changes:
Deleting from Permit:
• The permittee shall no longer sample effluent for cadmium, lead, or nickel. The
permittee shall continue to evaluate these metals under the Long Term Management
Plan.
• Conductivity -- due to the difficulties interpreting these data, the Division no longer
requires monitoring for receiving -stream conductivity.
Adding to Permit:
• Because there is "reasonable potential" for copper and zinc in this facility's effluent to
exceed Water Quality Stream Standards, the monitoring frequency for these two
parameters shall be increased from Monthly to 2/Month. All other parameters and
monitoring requirements remain unchanged.

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 13%.
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.

FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES Permit No. NC0032662
INTRODUCTION
City of Claremont / Claremont North WWTP (also herein referred to as 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 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 (superscripted numbers in order of appearance, See References).
FACILITY RECORDS REVIEW
Facility Description. The City of Claremont / Claremont North WWTP (Table 1) is a 0.100 MGD
Publicly Owned Treatment Works (POTW) utilizing a parallel dual -train wastewater treatment
system consisting of a 0.040 MGD train and a 0.060 MGD train, both discharging to Outfall 001 1'2.
Although the industrial influent to this plant represents approximately 19% (0.012 MGD) of current
effluent, there are currently no Significant Industrial Users (SIUs) I.

Page I

Division records date from 1974 when the plant's permitted capacity was 0.060 MGD. The previous
permit expired on June 30, 2000 and the Division received appropriate documentation to renew (Short
Form A) on January 4, 200014.
Waste Load Allocation (WLA). The Division prepared the last WLA in March 1995 and developed
effluent limits and monitoring considering an in -stream waste concentration (IWC) of 13 %. 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 Mull Creekl's, a Class WS-IV
stream within the Catawba River Basins. Mull Creek is not "impaired" [not 303(d) listed]6.
COMPLIANCE REVIEW
Pretreatment Compliance. In January 1999 the Division recognized two (2) Significant
Industrial Users (SIUs) contributing to this facility8. This is no longer true. This facility now
receives approximately 0.012 MGD (19%) industrial influent, but there is currently no SIU
discharging to Claremont North WWTP1.
Notices of Violation (NOVs). The Division has issued no NOVs for this facility within the last two
years.
Whole Effluent Toxicity (WET) Test. Quarterly monitoring results for Whole Effluent Toxicity
(WET) indicates "pass" for the last 22 quarters (August 1996 through September 2000)9'10.
Instream and Effluent Data Review. The Division reviewed over 32 months (1998 through
September 2000) of Discharge Monitoring Reports (DMR) data. Reports appear regular, thorough,
and complete. Total flow for this time period averages about 0.063 MGD (- 63 % of permitted
capacity)l°.
Instream Dissolved Oxygen and Temperature. Instream dissolved oxygen (DO) and temperaturedata
appear reasonable and seasonally appropriate. All DO values are compliant with the Stream Standard
minimum of 5 mg/L.
Instream Fecal Coliform. Weekly fecal coliform counts appear similar upstream to downstream.
Although counts range widely on any given day, the Division found similar values comparing
upstream to downstream data suggesting little or no correlation to facility discharge. Year 2000
monthly counts averaged 328 colonies per 100 ml (upstream) and 335 colonies per 100 ml
(downstream) with peaks ranging from >1540 upstream and >1720 downstream. Year 1999 data
indicate generally lower peaks and averages, but similar correlative conditions upstream to
downstream. The Division noted with some concern that the permittee regularly reports higher -value
counts using "greater -than" values instead of actual numbers of colonies.
Effluent Chlorine. Based on 33 months of data (1998 through September 2000) Total Residual
Chlorine (TRC) concentrations in effluent are moderate. They average less than 600 µg/L monthly,
and during the year 2000, less than 400 µg/L monthly.
Fact Sheet
Renewal -- NPDES NC0032662
Page 2

Reasonable Potential Analysis (RPA). The Division conducted EPA -recommended RPA analyses
on 32 months of data10 to determine the reasonable potential for identified toxicants to exceed Water
Quality Standards. The Division compiled five parameters of concern 4' 11 listed in the previous permit
and pretreatment LTMP documents including cadmium (Cd), copper (Cu), lead (Pb), nickel (Ni), and
zinc (Zn). Results suggest no "reasonable potential" for Cd, Pb, or Ni to exceed Water Quality
Standards. Furthermore, because these parameters are monitored under the Long Term Monitoring
Plan (LTMP), they will be removed from the Effluent Limitations and Monitoring Requirements
page.
Lastly, data suggest "reasonable potential" for state action -level parameters Cu and Zn. Because Cu
and Zn have North Carolina State Action Levels only, they are to be monitored only at a frequency
of 2/month (see below).
CORRESPONDENCE
Staff Report. Mooresville Regional Office (MRO) prepared a Staff Report dated May 22, 2000.
MRO staff found the facility "...in good operational condition..." and recommended that this permit
be reissued, as requested by the permittee2.
Facility Inspections. Mooresville Regional Office (MRO) described facility permit compliance as
"satisfactory" and within permit limits. Site inspectors in 1999 recorded minor "deficiencies" only
and issued no Notices of Violation. The Division requested the permittee to correct the following
deficiencies: 1) a 12- to 16- inch sludge mat observed at the bottom of the chlorine contact chamber;
and 2) intermittently inadequate flow -limit monitoring and reporting 12,13.
