ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QRT�RLY)
AW. 70 -
The permittee shall conduct acute toxicity tests on a ay= basis using protocols defined in the North Carolina
Procedure Document entitled "Pass/Fail Methodology For Detaining Acute Toxicity In A Single Effluent
Concentration." The monitoring shall be performed as a F�ead�nnow (Pimephales promelas 24 hour static
test, using effluent collected as a 24 hour composite. The effluent concentration at which there may be at no time
% (defined as treatment two in the North Carolina procedure document). Effluent
significant acute mortality is 90
samples for self-monitoring purposes must be obtained during representative effluent discharge below all waste
treatment.afirst test ' ®gerfjeed after thirty days from the effective date of this permit during the
months of `d ��-- bb
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR -1) for the month in which it was performed, using the parameter code TGE6C.
Additionally, DEM Form AT -2 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from either these monitoring requirements or tests performed by the North Carolina Division
of Environmental Management 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 and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.
