Subject: NPDES Permit Issuance
Permit No. NC0032662
North DW'TP
Catawba County
Class II Facility
Dear Ms. Renbarger:
Donald R. van der Vaart
Secretary
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES permit. 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 October 15, 2007 (or
as subsequently amended).
The final permit contains the following changes from the draft permit transmitted on September 23,
2015:
• The treatment facility description was updated to reflect existing equipment.
The final permit contains the following changes from your previous permit:
• As a result of a Reasonable Potential Analysis monitoring for total copper and total zinc
were reduced from monthly to quarterly. DMR data shows that these parameters don't have
reasonable potential to exceed the action level standards and the predicted maximum
concentration is greater than 50 % of the allowable concentration.
• Limits for ammonia were added to the effluent requirements. The Division is implementing
ammonia limits on permits that did not have limits in previous permits. In accordance with
an agreement with the EPA the Division must use the ammonia criteria of 1 mg/1 to
determine ammonia limits. The calculated limits in your permit are 6 mg/1 monthly average
and 18 mg/1 weekly average.
• According to the Statewide Mercury TMDL implementation guidance you will be required
to sample for mercury once during the permit cycle. See Special Condition A.(4).

• A special condition was added to the permit with requirements to rescind the permit when
connection to the McLin Creek WWTP is completed. See Special Condition A. (5).
• A special condition was added to the draft permit to address the Environmental Protection
Agency's (EPA's) pending requirement for you to provide electronically -submitted
Discharge Monitoring Reports (eDMRs). The Division intends to fully implement the
eDMR program as soon as practicable. See Condition A.(3) in permit. For information on
eDMR, registering for eDMR and obtaining an eDMR user account, please visit the
following web page:
http: / /portal.ncdenr.org/web/wq/admin /bog/ipu/edmr.
For information on EPA's proposed NPDES Electronic Reporting Rule, please visit the
following web site:
http://`vw\v2.epa.gov/compliance/proposed-npdes-electronic-reporting-rule.
If any parts, measurement frequencies or sampling requirements contained in this permit axe
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless
such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Resources or
any other Federal, State, or Local governmental permits that may be required.

Permit NC0032662
The Permittee shall discharge no floating solids or foam visible in other than trace amounts.
A. (2) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) [G.S. 143-215.1(b)]
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 December 2010, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised- December 2010) or subsequent versions. The tests will be performed during the months of
January, April, July, and October. These months signify the first month of each three-month
toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained
during representative effluent discharge and 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 -December 2010) 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,
DWR Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1623 Mail Service Center
Raleigh, North Carolina 27699-1623
Completed Aquatic Toxicity Test Forms shall be filed with the Water 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 Water 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. Assessment of toxicity compliance is based
on the toxicity testing quarter, which is the three month time interval that begins on the first day of the
Page 4 of 8

Permit NC0032662
month in which toxicity testing is required by this permit and continues until the final day of the third
month.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Resources 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. (3) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS [G.S. 143-
215.1(b)]
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees must
submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates
that these regulations will be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.)
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)

Beginning no later than 270 days from the effective date of this permit, the permittee shall begin
reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the
state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
Page 5 of 8

• Permit NC0032662
may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1,
2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to
the mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the date
the facility would be required under this permit to begin using eDMR. Temporary waivers shall be
valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
electronically to the Division unless the permittee re -applies for and is granted a new temporary
waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic
reporting requirements is found on the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following
the commencement of discharge.
2. Signatory Requirements (Supplements Section B. (11.) (b) and supersedes Section B. (11.)
LM

SUMMARY
The City of Claremont owns the North WWTP, a 0.10 MGD wastewater treatment plant operated by the
Town of Hickory. The treatment system consists of two treatment trains. One train is 0.04 MGD with a
coarse bar screen, aeration basin (diffused aeration), final clarifier, and sludge holding tank. The second train
is 0.060 MGD with coarse bar screen, aeration basin (mechanical and diffused aeration), final clarifier, and
aerated sludge holding tank. Both trains share the influent flow splitter, gas chlorination, chlorine contact
chamber, gas dechlorination, and flow measurement. The City is planning to connect this facility to the
McLin Creek WWTP and decommission the treatment system. An EAA for the expansion of the McLin
Creek WWTP was submitted to the Division on August 2015 and it includes the connection of the North
WWTP to McLin Creek WWTP.
RECEIVING STREAM
This facility discharges to Mull Creek in the Catawba River Basin, classified WS-IV waters in Sub -basin 03-08-
32, HUC 03050101. Mull Creek is not listed as impaired in the NC 2014 303(d) list.
DMR AND COMPLIANCE REVIEW
Notices of Violations (NOV) were issued for the following limits exceedances: BOD weekly average in
February 2013, January 2015, and February 2015, BOD monthly average in February 2013 and February
2015; TSS monthly average in February 2015, and monthly flow in May 2011. DMR were reviewed for the
period of January 2011 to June 2015. Data are summarized in Table 1.

Mercury Evaluation:
There is no data for mercury, as a minor facility no monitoring for mercury is required in the permit.
According to the implementation guidance for the Statewide Mercury TMDL the permit will have a special
condition requiring one sample during the permit cycle.
Aquatic Toxicity Testing:
Permit requires chronic toxicity, ceriodaphnia dubia, 13 %. The facility passed 18 out of 19 toxicity tests for the
period of January 2011 to July 2015. They failed one test in October 2014.
Reasonable Potential Analysis:
A reasonable potential analysis was completed for copper and zinc. These parameters don't show reasonable
potential to exceed the action level standards but the predicted concentration is higher than 50% of the
allowable concentration therefore monitoring frequency will be reduced to quarterly.
Instream Monitoring:
The permit requires instream monitoring for DO and temperature. Reported values show similar trends for
upstream and downstream locations and are within water quality standards.
LIMITS AND MONITORING REOUIREMENTS:
Current conditions, as well as the basis for the limits are summarized in Table 2.

2. Added a requirement to monitor mercury once during the permit cycle.
3. Added a special condition to require that the permittee rescinds the permit when the connection to
the McLin Creek WWTP is completed.
4. A special condition was added with requirements for submittal of electronic DMRs.

The City of Claremont'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 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 any further information is needed, please feel free to contact me at [phone]
