COMMENTS
These are existing limits for both wasteflows, except for revisions of
the NH3-N limit and the fecal coliform limit.
; For the current flow
of 0.1 MGD, the Region should give the facility the choice of the NH3
limits or toxicity testing. Both are not required. Upon expansion to
0.2 MGD, the NH3 limits should apply.
Downstream monitoring site has been moved to get farther away
from the discharge. Current downstream site is only 100 feet downstream.
Recommend instream monitoring of temperature, DO, fecal coliform, and
conductivity. '}'i.3ad n pia al(ogrs 47,2,4) iru.-easao+'••c-eese

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 concentration at which there may be no observable inhibition of reproduction or
significant mortality is 38 % (defined as treatment two in the North Carolina procedure
document). The permit holder shall perform guar. terly 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 Ate Tit , oc1-, Ian . 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 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 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.

Q✓ect,
These are the existing limits for a 0.2 MGD discharge. Facility expanded
before the reclassification of the receiving waters to ORW.
Metals limits and monitoring, and the toxicity requirement were added
as a result of a recent pretreatment headworks analysis. Data indicate
there may be a problem instream with each of the above metals. Recommend
effluent monitoring for these parameters be implemented as soon as
possible. Downstream monitoring site has been moved to get farther away
from the discharge. Current downstream site is only 100 feet downstream.
Recommend instream monitoring of temperature, DO, fecal coliform, and
conductivity.
