Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Two wasteloads were requested for this facility - one for a design flow of 0.1 MGD and one for a
design flow of 0.2 MGD. Since this discharge is into ORW waters, no additional loading will be
allowed when the facility increases flows above 0.1 MGD. A toxicity test will be required at flows
le s than 0.1 MGD, but this requirement will be dropped in lieu of ammonia limits above this flow.

Parameter(s) Affected

x Parameter(s) are water quality limited. For some parameters, the available load capacity of
the immediate receiving water will be consumed. This may affect future water quality based
effluent limitations for additional dischargers within this portion of the watershed.

CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity 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 e uent concentration at which there may be no observable inhibition of reproduction or significant mortality
is o (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
pe ormed Ater thirty days from the effective date of this permit during the months of
4. Jull> CYO ,l&1 . Effluent sampling for this testing shall be performed at the NPDES
ed 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
4401 Reedy Creek Road
Raleigh, N.C. 27607
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.

PART IV - EVALUATION AND RECOMMENDATIONS The existing
facility is designed for 0.10 MGD, the permit allows expansion to
0.20 MGD. The ORW basin plan requires that the additional 0.10
MGD not result in any increase in pollutant discharge above those
allowed for the original 0.10 MGD facility.
Additional construction for the second 0.1 MGD should include
provisions for ammonia reduction.
The facility is in good condition. Permit renewal is appropriate.
