ACUTE TOXICITY TESTING REQUIREMENT
Daphnid 48 hr - Monitoring for Episodic Events
The permittee shall conduct FIVE acute toxicity tests 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 pulex or Ceriodanhnia 48 hour static test, using
effluent collected as a single grab sample. Effluent samples for self -monitoring purposes must be
obtained below all waste treatment. Sampling and subsequent testing will occur during the first five
discrete discharge events after the effective date of this permit.
The parameter code for this test if using Daphnia nulex is TAA3D. The parameter code for this test
if using Ceriodaohnia is TAA3B. All toxicity testing results required as part of this permit
condition will be entered on the Effluent Discharge 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 pemut 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.
Failure to submit suitable test results will constitute a failure of permit condition.

(QRTRLY)
The effluent ' harge shall at no time exhibit chronic t xicity using test procedures outlined in:
1.) The North lina Ceriodaphnia chronic efflu t bioassay procedure (North Carolina Chronic
Bioassay Proced - Revised *February 1987) o subsequent versions.
The effluent concentrati at which there may no observable inhibition of reproduction or
significant mortality is (defined as tie tment two in the North Carolina procedure
document). The permit h ]der all perf, agarrerly monitoring using this procedure to establish
compliance with the permit condin • Th first test will be performed after thirty days from
issuance of this permit during the t of t1Aa, , M' . < p Ir (, . Effluent
sampling for this testing shall be perf at the NPDES permitted final effluent discharge below
all treatment processes.
All toxicity testing results requited part of thi m it condition will be entered on the Effluent
Discharge Monitoring Form (MR- for the mont in which it was performed, using the parameter
code TGP3B. Additionally, DE Form AT-1 (origi al) is to be sent to the following address:

permit may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to ach' ve test conditions as specified in the cited document, such as minimum
