Facility Class IV
Dear Mr. Lamberth:
Division personnel have reviewed and approved your application for a renewal of the subject
permit. Accordingly, we are forwarding the attached NPDES discharge 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 following changes have been incorporated into this renewal:
• 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.
The requirement to begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) Internet application has been added to your
NPDES permit. [See Special Condition A. (6)] For information on eDMR, registering for eDMR
and obtaining an eDMR user account, please visit the following web page:

Permit NC0046728
A. (3). CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 90%.
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 February, May, August and November.
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, DWR Form AT-3 (original) is to be sent to the
following address:
Attention: NC DENR / DWR / Environmental Sciences Section
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 Resources 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.

SUMMARY
The Town of Mooresville has applied for a renewal of the NPDES Wastewater permit. Recently, the
facility has been granted an interim expansion of the permitted flow from 5.5 MGD to 7.5 MGD for
their Rocky River WWTP. There are no industrial users discharging to the plant (previous models
conducted had high industrial input).
Dye Creek is listed on the 303(d) list based on biological impairment. Based on review of WET results,
the WWTP is not contributing to instream toxicity.
The FONSI for the expansion project has been released from the State Environmental Review
Clearinghouse on July 21, 2009. The permit limits for the expanded flow have been established in
accordance with the Speculative Effluent Limits Letter that was sent on February 20, 2006. The
expansion incorporated tertiary filters and UV disinfection, so the entire plant can operate at 5/1 limits
for BOD and ammonia -nitrogen.
INSTREAM MONITORING
The Mooresville - Rocky River WWTP is a member of the Yadkin Pee Dee River Basin Association, so
its instream monitoring requirements are waived. At this time, however, there are no coalition
monitoring stations in the vicinity of the discharge.
RPA
Reasonable potential analyses (RPA) was conducted for Cu, CN, Pb, Hg, and Zn. Only Cn has a
reasonable potential to exceed the water q»ality standards. Please see attached.

TOXICITY TESTING
Chronic P/F @ 90% at 5.5/7.5 MGD using Ceriodaphnia.
No change to the toxicity testing condition is recommended at this time. The facility passed all whole
effluent toxicity (WET) tests for during the last 5 years.
COMPLIANCE SUMMARY
A review of the facilities compliance data during the last 5 years identified three Notcied of Violation,
one for violationg a mercury limit, and two for violation BOD limit.
MERCURY EVALUATION
The mercury evaluation was conducted in accordance with the Permitting Guidelines for Statewide
Mercury TMDL.

WQBEL allowable concentration for this facility is 12.5 ng/L. All Annual average mercury
concentrations are below allowable. All maximum sampling results are below TBEL of 47 ng/L. Based
on the Permitting Guidelines for Statewide Mercury TMDL, the Mercury Minimization Plan will be
added to the permit. The limit and monitoring will be removed from the permit. The facility will
continue mercury monitoring through PPA.
PERMIT LIMITS
• BOD limits in the permit are based on the water quality model.
• DO limit in the permit is based on the water quality model.
• Ammonia limits in the permit are based on the water quality model. The Division uses ammonia
criteria that were developed by EPA: 1 mg/L - summer; 1.8 mg/L — winter.
• TSS limits in the permit are based on the requirements of the 40 CFR 133.102.
• Fecal Coliforms limits in the permit are based on the North Carolina water quality standards
[15A NCAC 2B .0200].
• pH limits limit in the permit are based on the North Carolina water quality standards [15A
NCAC 2B .0200].
• Cyanide limits in the permit are based on the results of the Reasonable potential Analysis.
SUMMARY OF PROPOSED CHANGES
• A weekly average effluent limit for Cyanide was removed from the permit and a new daily
maximum limit added to the permit to meet the requirements of 40 CFR 122.45 (d).
• Monitoring for Cyanide was reduced to Monthly based on the results of the Reasonable
Potential Analysis.
• Monitoring for Total Copper, Total Lead, and Total Zinc was reduced to Quarterly based on the
results of the Reasonable Potential Analysis.

• Based on the Permitting Guidelines for Statewide Mercury TMDL, the Mercury Minimization
Plan will be added to the permit (see A. (6.), and the limit and monitoring for Total Mercury will
be removed from the permit. The facility will continue mercury monitoring through PPA.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE
Draft Permit to Public Notice:
Permit Scheduled to Issue:
September 10, 2013 (est.)
November 4, 2013 (est.)
NPDES DIVISION CONTACT
If you have questions regarding any of the above information or on the attached permit, please contact
Sergei Chernikov at [phone].
CHANGES IN THE FINAL PERMIT:
• 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
perrnittees must submit DMRs electronically to the Environmental Protection Agency (EPA).
The Division anticipates that these regulations will be adopted and is beginning implementation.
The requirement to begin reporting discharge monitoring data electronically using the NC
DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been added to
the permit. [See Special Condition A. (7.)].
