CHRONIC TOXICITY TESTING REQUIREMENT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests,
using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentratioaat which there may be no observable inhibition of reproduction or
significant mortality is 1 • % (defined as treatment two in the North Carolina procedure
document). The permit holder shall perform quarter1v monitoring using this procedure to establish
compliance with the permit condition. The first test will be perfonved after thirty days from
issuance of this permit during the months of TC n 1` J v l O 0 tK . Effluent
sampling for this testing shall be performed at the NPtDE ermittedfinal effluent discharge below
all treatment processes. p g
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 TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences 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 chemicaVphysical 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 single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement 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 noncompliance with monitoring requirements.

Biocide - Betz C-77, C-78-BCDMH additive. Form 101 attached - Ref. letter
R. Paul Wilms to J D. Henderson 10/2/87 expressed concern for
carryover of residual chlorine from this additive. Recommended
testing was conducted. Following two months testing (results
attached) meeting was held with DEM, at which time DEM
indicated further testing was not necessary due to low chlorine
carryover and the additive was approved for use. Ref. letter dtd.
