ACUTE TOXICITY TESTING REQUIREMENT (QRTRLY)
Daphnid 48 hr - LC50
The pemuttee shall conduct acute toxicity tests on a 0jarter basis 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 vulex or Ceriodaphnia
48 hour static test, using effluent collected as a 24 hour composite. The LC50 of this effluent
using the previously stated methodology may not at any time be less than ` z/ %. Effluent samples
for self -monitoring purposes must be obtained during representative effluent discharge below all
waste treatment. The first test will be performed Ater thirty days from issuance of this permit
during the months of r it TU
w , s-t.j2 ,fie C,
The parameter code for this test if using Daphnia pulex is TAA3D. The parameter code for this test
if using Ccriodaphnia is TAA3B. 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 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 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.
