Permit NC0000078
A. (3) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality
to Ceriodapbnia dubia at an effluent concentration of 12% at 13.0 MGD or 22% at 27.5 MGD.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
"North Carolina Ceriodapbnia 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: 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 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 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.
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.
Permit NC000007g
A. (4) AMMONIA NITROGEN CONDITION
This permit may be modified, or revoked and reissued to include NH3-N limitations and monitoring
requirements in the event monitoring conducted on the effluent indicate that NH3-N concentrations are
greater than 4.0 mg/L.
A. (5) DIOXIN MONITORING
Adequate sample volume shall be collected to perform the analysis. The total sample volume shall be
collected and preserved in accordance with Part II, Section C Monitoring and Records. The sample shall be
analyzed in accordance with the appropriate method of analysis specified in Analytical Procedures and
Quality Assurance for Multimedia Analysis of Polychlorinated Dibenzo-para-dioxins and Polychlorinated
Dibenzofurans by High Resolution Gas Chromatography/High Resolution Mass Spectrometry, EPA, 1987
(EPA Method 1613), or another equivalent analytical protocol approved by DWQ. A single sample may be
analyzed to determine compliance with the daily maximum effluent limitation. Alternatively, a sample
volume may be collected to enable the sample to be split (duplicate analysis). If the analysis of either split
sample is below the detection limit, the quantity, for the purposes of compliance evaluation, is considered to
be zero. If both splits are positive, the results of the two analyses shall be averaged to determine compliance
with the daily maximum effluent limitation. If the measurement is below detection limits, the quantity for
the purposes of compliance evaluation is considered to be zero. The detection limit using these methods
for the purpose of compliance evaluation is considered to be 10 picograms per liter. The dioxin isomer to
be monitored and limited by this permit is 2, 3, 7, 8, TCDD.
Fish tissue analysis will be performed, as a minimum, at one station established upstream of the discharge
and at two stations downstream in accordance with the Division's approved monitoring plan. The
monitoring plan is an enforceable part of this permit. All dioxin data collected pursuant to this monitoring
requirement will be reported within three months after collection.
The Permittee shall perform fish tissue analyses for TCDD and TCDF tri-annually (once every 3 years). If
the data from annual fish tissue analysis indicates there are no dioxin concerns, an alternative schedule may
be granted.
A. (6) MERCURY FISH TISSUE SAMPLING
The Permittee shall conduct fish tissue sampling for Mercury on a tri-annual basis (once every 3 years). The
Division's Environmental Sciences Section shall approve the fish -tissue sampling plan prior to
commencement of sampling.
A. (7) CHANGE OF OWNERSHIP
a. Within sixty days after a change in ownership, the following shall be submitted to the
Division:
1 proof of the change in ownership;
2. a request to transfer the permit to the Purchaser of the facility;
3. a completed and signed EPA Form 1; and
4. a statement indicating whether any physical alterations or additions to the permitted facility are
planned which meet the notice requirements of Part II E.2 of this permit.
[If no changes are planned, the Division shall transfer the permit to the Purchaser as a minor
modification. If any physical alterations or additions to the permitted facility are planned which meet the
notice requirements of Part II E.2, the Purchaser shall provide the following additional information]
Permit NC0000078
5. A new application for the modified discharge, completed and submitted by the new owner of
the facility
6. A request for a major modification of permit NC0000078.
7. Fee payment for a major permit modification.
8. A complete flow justification for the proposed discharge and an Engineering Alternatives
Analysis (EAA).
When all of the above actions are completed, the Division shall provide a modified permit appropriate for
the proposed discharge or set of discharges.
b. During the next permit renewal, the Permittee shall submit a complete flow justification for
the proposed discharge and an Engineering Alternatives Analysis (EAA).
A. (8) DAM INTEGRITY
The Permittee shall inspect the ASB dam annually. The permittee shall provide proper maintenance of the
