ACUTE TOXICITY TESTING REQUIREMENT(QRTRLY)
Fathead Minnow 24 hr- No Significant Mortality
The permittee shall conduct acute toxicity tests on a Quarterly basis using protocols defined in the
North Carolina Procedure Document entitled "Pass/Fail Methodology For Determining Acute
Toxicity In A Single Effluent Concentration". The monitoring shall be performed as a Fathead
Minnow (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 significant acute mortality
is 90% (defined as treatment two in the North Carolina rocedure document). Effluent samples for
P P
self-monitoringpurposes must be obtained duringrepresentative effluent discharge below all waste
g
treatment. The first test will be performed after thirty days from issuance of this permit during the
months of Apr , `V.Q Oct, Sties
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: Technical Services Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
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 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 a failure of permit condition.
