•
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. 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 & 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.

Good morning Mr. Corporon.
The City of Hickory is contract operator and manager for the City of Claremont for this facility.
I have tried calling a couple of times now to ask a few questions about the Draft permit prior to submitting official
comments. As I shared on my voicemails, the Draft permit calls for daily fecal sampling versus the previous permitted
weekly sampling. There have been no fecal permit violations and I can not find a reasonable potential for anticipated
impacts. I have discussed this with the Regional Office and they agreed that this seems to be an oversight in the permit
draft. Can you review this and verify that this is the intention or not as a permit condition modification? As you are aware,
to implement a daily regime of fecal sampling would be very costly for the overall operations of the facility. Currently the
weekly sample is drawn in concert with all the other weekly sampling and analyzed at the City of Hickory Regional
Laboratory. To switch this condition to a daily sample would require Lab staff to drive to the facility and sample for fecal
solely. This is both cost prohibitive and inefficient in our overall operations. Also, the existing permit and rightfully so the
Draft contains the comminutor as a treatment process. We are interested in exploring the potential for eliminating this
piece of equipment from the permitted treatment processes. This piece of equipment has been problematic in the past
and truly serves no beneficial process to the treatment facility. We would like to discuss the potential for removing this
process from the permit.
Please let me know at your earliest convenience about these matters or when would be good to call and discuss.
We truly appreciate all the work the Division is doing and appreciate your assistance with review of these issues.
The cover letter gives us till March 18 to provide comment, however we would like to go ahead and wrap these few
comments up if you feel this would be helpful.
Respectfully

COMPLIANCE REVIEW
Division Records and Permittee's Renewal Application. Claremont North began operation in
1974 when the plant's permitted capacity was 0.060 MGD. This last permit expired on July 31, 2010
and the Division received prompt documentation to renew (Short Form 2A) on February 2, 2010. The
Permittee has transferred daily operations to the City of Hickory (David Greer, ORC) who requested
the Division to remove from the permit all reference to influent comminutors because they have
discontinued using them. This request is reflected in the permit final.
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 Creek [Stream Segment 11-
76-4], a Class WS-IV stream within the Catawba River Basin. Mull Creek is not "impaired"
according to the Division's list of impaired water [303(d) list, 2010 DRAFT].
Discharge Monitoring Report (DMRs) and Effluent Data Review. The Division reviewed
effluent data as submitted, recorded and reported by the Basinwide Management System (BIMS) for
the compliance period January 2007 through September 2010. DMR data appear regular, thorough,
and complete. Monthly effluent flows for this time period averaged 0.59 MGD (-60 % of permitted
flow) with a high of 0.171 MGD in 1,765 reports.
Effluent Total Residual Chlorine (TRC). A Daily Maximum TRC limit of 28 µg/L was added to the
previous permit. A note has been added for renewal explaining that values reported less than 50 ug/L
shall be considered compliant with the permit, in accord with statewide policy for chlorine (see
footnote for TRC, section A. (1.).
Whole Effluent Toxicity (WET) Testing. The Division reviewed quarterly Whole Effluent Toxicity
records from January 2001 through July 2010 (36 quarterly tests). The Permittee passed all quarterly
toxicity tests.
Notices of Violation (NOVs) and Penalty Assessment. The Division examined compliance records
from March 2006 through December 2010. This facility received no violations or penalty assessments
since December 2007.
Pretreatment Compliance. Currently, this facility does not have Significant Industrial Users (SIUs).
Therefore, 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 2004 through June 2005),
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 (%2 FAV) for freshwater (Table
3). If, by this method, a POC shows reasonable potential to exceed its % FAV, the Division includes a
permit limit as a Daily Maximum to protect the receiving stream against acute toxic affects. Similarly, if
the maximum exceeds the chronic standard, a Weekly Average limit is added to the permit.
Fact Sheet 2011
Complex Expedited Renewal - Permit NC0032662
Page 2

This facility's POCs, as defined above, include copper and zinc. The Division regulates copper and zinc
as "action level" parameters, therefore these POCs will not receive permit limits in the absence of
significant failures in Whole Effluent Toxicity (WET) testing.

RENEWAL SUMMARY
Effluent Monitoring
Copper and zinc both show "reasonable potential" for acute toxicity; Zinc also show
reasonable potential to exceed its chronic standard. Therefore, monitoring of both parameters
will continue — no permit limits, in accordance with statewide policy for "action level"
parameters. The Division has added a footnote for TRC — "...any value below 50 µg/L will
be compliant...," in accordance with statewide policy.

City of Claremont North WWTP
Claremont, North Carolina
Dear Ms. Sprinkle:
The City of Clarmeont's North 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].
