Dear Mr. Noland:
Division personnel have reviewed and approved your application for renewal of the subject
permit. Accordingly, we are forwarding the attached NPDES discharge permit. This pertnit 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 permit renewal:
• The effluent was evaluated in accordance with the Monitoring Frequency Reduction Review
Guidance. The facility has met the requirements of the guidance for BOD, TSS, ammonia
nitrogen, and fecal coliforms. Therefore, monitoring for these parameters will be reduced to
2/Week.
• A special condition Permit Re -Opener was deleted.
• The special condition A. (9.) Effluent Pollutant Scan was updated.
• A new footnote wording for the total residual chlorine limit has been added.
• The effluent page for 16 MGD flow was removed.
• The quarterly monitoring for zinc, copper, and silver was removed based on the results of
the Reasonable Potential Analysis.
The Division cannot grant your request to eliminate monitoring for mercury. The NPDES
Permitting policy for implementation of the Statewide Mercury TMDL requires to determine if the facility

A. (4.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)- for 21 MGD
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 4.6%.
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:

Dear Mr. Chernikov:

DENR-WATER QUALITY
POINT SOURCE RANCH
The Public Works Commission of the City of Fayetteville is in receipt of the draft NPDES Permit, which
was sent to public notice on July 17, 2012. We would like to submit the following comments.
1. Mercury monitoring
PWC objects to the quarterly mercury monitoring requirement. All of our mercury data is non -detect and
accordingly, there is no basis for a limit or quarterly monitoring. We specifically object to any effort by
DWQ to assign one-half the detection level to our effluent results. This is unprincipled and technically
and legally incorrect. There may be merit to running statistical analysis on data sets that contain both
detect and non -detect values; however that is not the case for a data set with all non -detectable results.
Additionally, PWC should be given the benefit of the significant available dilution. We disagree that any
blanket statewide impaired waters listing for mercury trumps the normal mixing zone rules. We are not
aware of any such provision in any State or Federal statutes or regulations.
Moreover, the quarterly mercury monitoring requirement is inconsistent with DWQ's Mercury Permitting
Strategy, which will be implemented when the mercury TMDL is adopted. We understand that the
TMDL is scheduled for consideration at the September EMC meeting. PWC requests that issuance of this
permit be delayed until after the TMDL and Permitting Strategy are adopted and that prior to issuance the
permit be modified consistent with the Permitting Strategy.
2. Frequency of Monitoring
PWC requested reduced monitoring for CBOD, TSS, ammonia, fecal coliform and Whole Effluent
Toxicity (WET). Your cover letter states "The monitoring frequencies for these parameters are
established by 15A NCAC 2B.0500". While this is true, 15A NCAC 2B.0508(b) also states "If it is
demonstrated to the satisfaction of the Director that any of the tests and measurements, sampling points,
BUILDING COMMUNITY CONNECTIONS SINCE 1905

v 4
or frequency of sampling requirements, as required in this rule for a particular SIC group, are not
applicable to the discharge of a particular water pollution control facility, or if it can be demonstrated that
the objectives of this Section can be achieved by other acceptable means, then such requirements may be
waived or modified to the extent that the Director determines to be appropriate."
In discussions with Jeff Poupart and Chuck Wakild, DWQ agreed that this language allows DWQ to
implement reduced monitoring frequencies. DWQ has committed to implementing reduced monitoring
for facilities that demonstrated exemplary compliance histories. DWQ committed to developing criterion
for determining which facilities would qualify for reduced monitoring by June 2012. This deadline was
not met and currently the NC Water Quality Association and DWQ are scheduled to meet on August 23,
2012 to develop this criterion.
In our permit renewal application, PWC provided data that demonstrated there is no significant difference
in 5 day per week sampling verses 1 day per week sampling and no significant difference which day of
the week the samples are collected. Two or three times per week sampling is more than sufficient to
demonstrate compliance at this facility for CBOD, TSS, ammonia, and fecal coliform.
During the last permit cycle PWC has run 22 aquatic toxicity tests with only one failure, which was an
anomaly. One failure out of 22 tests is well within the expected variability rate for WET testing. At the
current permitted flow of 21 MGD, this facility has an instream waste concentration of 4.6 percent. The
average influent flow is 13.66 MGD, of which 99.9 percent is domestic. The historical WET testing
clearly demonstrates that this facility's discharge is not toxic and there is no basis for continued quarterly
monitoring.
Finally, the continued requirement to run daily CBOD, TSS, ammonia, and fecal coliform and quarterly
WET testing is an unnecessary and inefficient use of resources. PWC is confident that this facility will
qualify for reduced monitoring once the criterion are adopted and requests that issuance of the permit be
delayed until the criterion are in place. At a minimum, we request that a clause be added that will
automatically afford reduced monitoring once DWQ's updated monitoring guidelines are adopted.
Thank you for consideration of these comments.
Sincerely,

Cape Fear Monitoring Coalition, and all its in -stream monitoring is conditionally waived for
the duration of its membership in the Coalition. Rockfish Creek has 2 significant industrial
users and a full-scale pretreatment program. The permit will continue to require PWC to
implement its pretreatment program.
REASONABLE POTENTIAL ANALYSIS (RPA)
The RPA was conducted for arsenic, copper, cyanide, cadmium, chromium, lead, mercury,
molybdenum, nickel, silver, selenium, phenol, and zinc. Please see attached.

January, April, July, and October.
The permittee has been consistently passing WET tests during the last permit term with one
exception. The facility failed WET test in April of 2008, the subsequent tests conducted in
May and April of the same year passed.
COMPLIANCE REVIEW
DMR records indicated the facility had good compliance history from January 2006 through
December 2011 reporting period. Facility had only two CBOD5 limit exceedances in April
2006 and July 2008.
INSTREAM DATA REVIEW
Coalition instream monitoring data was reviewed for the period beginning April 2009
through April 2012. Instream monitoring is required for dissolved oxygen, conductivity, and
temperature. Monitoring is conditionally waived based on the participation in the Cape Fear
River Basin Monitoring Coalition. The analysis of DO and temperature indicates that the
facility has a very small impact on the receiving stream (Coalition Instream Monitoring Data
attached).
PROPOSED CHANGES
• The special condition A. (10.) was updated.
• A new footnote wording for the total residual chlorine limit has been added.
• The effluent page for 16 MGD flow was removed.
• The quarterly mercury monitoring was added based on the results of the
Reasonable Potential Analysis.
• The quarterly mercury monitoring for zinc, copper, and silver was removed
based on the results of the Reasonable Potential Analysis.
