ACUTE TOXICITY TESTING REQUIREMENT
Daphnid 48 hr - Monitoring for Episodic Events
The pernuttee shall conduct FIVE acute toxicity tests using protocols defined in E.P.A.. Document
600/4-85/013 entitled "The Acute Toxicity of Effluents to Freshwater and Marine Organisms".
The monitoring shall be performed as a Daphnia Lp ilex or Ceriodaphnia 48 hour static test, using
effluent collected as a single grab sample. Effluent samples for self -monitoring purposes must be
obtained below all waste treatment. Sampling and subsequent testing will occur during the first five
discrete discharge events after the effective date of this permit. After monitoring of the first five
toxicity tests, the permittee will conduct one test annually, with the annual period beginning in
January of the next calendar year. The annual test requirement must be performed and reported by
June 30. If no discharge occurs by June 30, notification will be made to the Division by this date.
Toxicity testing will be performed on the next discharge event for the annual test requirement.
The parameter code for this test if using Daphnia tp ilex is TAA3D. The parameter code for this test
if using Ceriodaphnia is TAA3B. All toxicity testing results required as part of this permit
condition will be entered on the Effluent Discharge Form (MR-1) for the month in which it was
performed, using the appropriate parameter code. Additionally, DEM Form AT-1 (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 chenucal/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.
Failure to submit suitable test results will constitute a failure of permit condition.
