Permit NC0028835

A. (4) CHRONIC TOXICITY PERMIT LIMIT (Quarterly – 3 MGD)

The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to 

Ceriodaphnia dubia at an effluent concentration of 0.41%.

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: 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.

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 (Quarterly – 5 MGD)

The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to 

Ceriodaphnia dubia at an effluent concentration of 0.51%.

“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.
