ACUTE TOXICITY TESTING REQUIREMENT(QRTRLY)
Daphnid 48 hr-LC50
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined as
definitive 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 pulex 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 at no time in any two consecutive toxicity
tests be less than. 11%. Effluent samples for self-monitoring purposes must be obtained during
representative F:_luent discharge below all waste treatment.The first test will be perfolmed after
thirty days from issuance of this permit during the months of 3'. l Sof t►-t
The parameter code for this test if using Daphnia pulex 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 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:
