TOXICITY TESTING REQUIREMENT
The effluent discharge shall at no time exhibit chronic toxicity using
test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay proce-
dure (North Carolina Chronic Bioassay Procedure - Revised *February 1987) or
subsequent versions.
The effluent concentration at which there may be no observable inhibi-
tion of reproduction or significant mortality is RC( $ (defined as treatment
two in the North Carolina procedure document). The permit holder shall
perform rAp,6,A4 monitoring using this procedure to establish compliance
with the LliermitJondition. The first test will be performed within thirty
days from issuance of this permit. Effluent sampling for this testing shall
be performed at the NPDES 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 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 chemi-
cal/physical measurements performed in association with the toxicity tests,
as well as all dose/response data. Total residual chlorine must be measured
and reported if chlorine is employed for disinfection of the waste stream.
Should any test data from this monitoring requirement or tests per-
formed 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 docu-
ment, such as minimum control organism survival and appropriate environmen-
tal controls, shall constitute an invalid test and will require immediate
retesting. Failure to submit suitable test results will constitute a fail-
ure of permit condition.

SUBJECT:
City of Reidsville
(NCO024881)
A wasteload allocation request for the City of Reidsville (request
number 3812) has been circulated, however it has been brought to our atten-
tion that the limit for cyanide needs to be revised to 0.005 mg/l. Please
note and make any necessary revisions.
Also the City should be made aware that their next permit will likely
contain limits for not only cyanide but also chromium, nickel and lead.
Additional monitoring of the facility's effluent may also be required.
The permit limits should read as follows:
Summer
Winter
Qw:
5.0
5.0 MGD
BODS:
6
12 mg/1
NH3N:
2
4 mg/1
D.O.:

TSS:

PH:

Total Phosphorus:

2 mg/1
Cyanide:
0.005
0.005 mg/1
In addition the facility is responsible for a toxic testing requirement
(quarterly -chronic at 99%) and instream self- monitoring for D.O., tempera-
ture, conductivity and fecal coliformu rfe� at-ME-:t-3 and downstream at
