2. The Total Residual. Chlorine (TRC) monitoring and limit requirements apply only if chlorine or chlorine
derivative is used for. disinfection. The Division shall consider all effluent TRC values reported below 50
µg/L to be in compliance with the permit. However, the permittee shall continue to record and submit all
values reported by a North Carolina certified lab (including field certified), even.if.these values fall below 50
µg/L. Again, only applicable if chlorine is used..
3. The temperature of the effluent shall not cause an increase in temperature of the receiving stream of more
than 2.8°C. In no case shall the temperature of the effluent cause the ambient water temperature to exceed.
32°C. .
4. The daily average Dissolved Oxygen effluent concentration shall not be less than 5.0 mg/L.
5. Samples collected must be analyzed by EPA_Method 1631.
6. Chronic Toxicity (Ceriodaphnia) P/F at 67%: January, April, July, October (see. Part I. A. (3) below).
There shall be no.discharge of floating solids or visible foam in other than trace amounts.

A. (2) MERCURY REOPENER
The Division may re -open this permit to require mercury load limits, mercury minimization
plans, and/or. source water characterization following completion of the Phase.2 Mercury
TMDLs for the Lumber and Waccamaw River watersheds.
A. (3) CHRONIC. TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 67%.
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 & 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:
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 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 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.
Permit NC0035904
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.
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.
