1.) The permittee shall conduct chronic toxicity tests on a quarterly
basis using protocols defined in E.P.A. Document 600/4-85/014
entitled "Short -Term Methods for Estimating the Chronic Toxicity
of Effluents and Receiving Waters to Freshwater Organisms". The
testing shall be performed as a Ceriodaphnia Survival and Repro-
duction Test. Effluent collection will be performed twice during
each test as 24 hour composite samples. Toxicity test exposure
using the first composite sample will include the first three full
days of testing. Exposure to the second composite sample will in-
clude the last four full days of testing. Effluent samples will
be taken immediately prior to disinfection, but below all other
treatment processes. "fie Chronic Value (ChV) must be greater than
ll.o X. There will be minimally five effluent concentrations and a
control exposure treatment. One effluent concentration shall equal
Oa X, which represents the instream waste concentration (I.W.C.)
during 7Q10 low flow conditions and daily permitted d4--:'1volume.

Note:- Failure to achieve test conditions as specified ins:the cited
document, such as minimum control organism survival and appropriate
environmental controls, shall constitute an invalid test and will re-
quire immediate retesting. Failure to submit suitable' teat results
will constitute a permit violation.
