Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
The previous WLA for Oakboro was performed for their exisitng discharge on Long Creek and for
the possible relocation to the Rocky River.
Compliance data indicate no violations. The facility has had only 1 toxicity failure since 1991.
Instream data indicate D.O.'s < 5 mg/1 up and downstream on Long Creek.
Permit renewal does not indicate that Oakboro wants an expansion to 1 MGD with the relocation
(they had requested a speculative in the past for this).
Carolina Solite discharges on the Rocky River near the proposed Oakboro discharge. Oakboro
will not be given total allowable metals limits due to the proximity of the Carolina Solite discharge.
TSB recommends that the facility retain the metals limits allowed on Long Creek even when
Oakboro relocates to the Rocky River. The facility should receive the less stringent toxicity testing
requirement on the Rocky River due to dilution.
No NH3-N/tox choice will be required since the facility has been passing its toxicity testing
requirement.
The ongoing study of the Rocky River may require minimum treatment limits for any discharges to
the River in the future. This may require more stringent BOD5, NH3-N and nutrient limits.

Elevated effluent levels
Parameter(s) Affected
Cd-observed value below detection
and no pretreatment limits, Pb,Cr
(no pretreatment requirements, but
some elevated observed values),
Hg, As
Ni, CN
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.
OR
No parameters are water quality limited, but this discharge may affect future allocations.

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

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 effluent concentration at which there may be no observable inhibition of reproduction or significant mortality
is _t % (definedas treatment two in the North Carolina procedure document). The permit holder shall perform
Quarter& monitoring using this procedure to establish compliance with the permit condition. The first test will be
performed after thirty days from the effective date of this permit during the months of
1u� 1 6e.T . 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
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 wells alldose/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.
