Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Renewal per basin plan. Last WLA 5/89. Town has received ATC for 1.0 MGD. Since a toxicity
test required, no ammonia limits will be required at this time (summer allowable is 12 mg/1).
Renew with existing limits.
This WLA is a resubmittal.

Parameter(s) Affected
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.
X'
No parameters are water quality limited, but this discharge may affect future allocations.

MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Adequacy of Existing �Treatment
Has the facility dem nstrated the ability to meet the proposed new limits with existing treatment
facilities? Yes No
If no, which parameters cannot be met?
Would a "phasing in" of the new limits be appropriate? Yes No
If yes, please provide a schedule (and basis for that schedule) with the regional
office recommendations:
If no, why not?
Special Instructions or Conditions
Wasteload sent to EPA? (Major) (Y or N)
(If yes, then attach schematic, toxics spreadsheet, copy of model, or, if not modeled, then old
assumptions that were made, and description of how it fits into basinwide plan)
Additional Information attached? (Y or N) If yes, explain with attachments.

CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
(**Chronic Toxicity (Ceriodaphnia) ChV at.�%,Jkly, rM,.jut., ocT , See Part,21, Condition H .)
The effluent discharge shall at no time exhibit 48 hour acute toxicity as lethality in an
effluent concentration of --�, % nor measure a quarterly arithmetic average chronic value
less than this same percentage of waste. The chronic value will be determined using the
geometric mean of the highest concentration having no statistically detectable impairment of
reproduction or survival and the lowest concentration that does have a statistically
detectable impairment of reproduction or survival. The presence of 48 hour acute toxicity
will be determined using Fisher's Exact Test at 48 hours from test initiation. Collection
methods, exposure regimes, and further statistical methods are defined in: The North
Carolina Phase H Chronic Whole Effluent Toxicity Test Procedure (July, 1991) or
subsequent versions.
The permit holder shall perform at a minimum, quarterly monitoring using these procedures
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 J AN u -r
Effluent sampling for this testing shall be performed at the NPDES pernutted final effluent
discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter measures 48 hour acute
toxicity or a chronic value less than that specified above, then multiple concentration testing
shall be performed, at a minimum, in each of the two following months.
All toxicity testing results required as part of this permit condition will be entered on the
Effluent Discharge Monitoring Form (MR-1) for the months in which tests were
performed, using the parameter code THP3B for the Chronic Value and TGA3B for the 48
hour Acute Toxicity measure (Pass/Fail). Additionally, DEM Form AT-3 (original) is to be
sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, NC 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 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.
