Subject: NPDES Draft Permit
Permit No. NC0050105
Rockfish Creek WRF
Cumberland County
Facility Class IV
Dear Mr. Noland:
Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very
carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains following significant changes from your current permit:
• 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. -
• A mercury TMDL re -opener was added to address upcoming implementation of the TMDL.
The Division is unable to grant your request to reduce the monitoring frequency for CBOD, TSS, NH3-N,
Fecal Coliform, and Whole Effluent Toxicity. The monitoring frequencies for these parameters are
established by 15A NCAC 2B .0500..
Please submit any comments to me no later than thirty days following the public notice date. Comments
should be sent to the address listed at the bottom of this page. If no adverse comments are received from

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:
Attention: Environmental Sciences Section
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 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 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.
A. (5.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)- for 24 MGD
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 5%.

The Permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed below. One scan
must be performed in each of the following years: 2013, 2014, and 2015. Analytical methods shall be in
accordance with 40 CFR Part 136 and shall be sufficiently sensitive to determine whether parameters are present in
concentrations greater than applicable standards and criteria. Samples should be collected with one quarterly toxicity
test each year, and must represent seasonal variation [i.e. do not sample in the same quarter every year]. Unless
