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 *February 1987) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is qg % (defined as treatment two in the North Carolina procedure
document). The permit holder shall perform quarterly monitoring using this procedure to establish
compliance with the permit condition. The first test will be performed after thirty days from
issuance of this permit during the months of filar Jun Sep Dec. . Effluent
sampling for this Testing shall be performed at the 1TIPD'ES permitted final effluent discharge below
all treatment processes.
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: 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 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.

RECOMMENDATIONS
1 ) The CMUD-McAlpine WWTP should continue quarterly performance of the seven
day Ceriodaphnia dubia pass/fail
at the facility's IWC of 99.527-
reproduction suppression toxicity test
Thn .siihject
should have toxicity limits included.
2.) The facility should submit to DEM a
.., 'T.on isudrice,
written toxicity reduction plan with
a proposed schedule of attaining compliance.
3.) Sources of elevated levels of copper, lead, and zinc should be located
and discharge of these constituents reduced.
i 4.) The source of lindane should be located and discharge of this constituent
reduced to acceptable levels.
5.) Treatment efficiency should be maximized for the decrease of ammonia
concentrations in the effluent.
6.) Effluent metal concentrations should be analyzed as both dissolved and
total levels in an effort to address whether the concentrations detected
may be biologically available. Alternatively, effluent fractionation
toxicity testing procedures may be able to determine whether metals may
be contributing to toxicity.
