Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Limits for expanded flows are based on no net increase in loading for oxygen consuming wastes.
Chlorine and Fecal Coliform limits were changed according to SOP. Instream data is very limited
in this area. Any new evidence indicating water quality problems in this subbasin may affect future
limits for this facility as they are implemented in the Basinwide Management Plan.

Parameter(s) Affected
BOD, NH3N, Chlorine
Fecal Coliform
_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.

INSTREAM MONITORING REQUIREMENTS
Upstream Location: SR 1301 Bridge
Downstream Location: NC 11 Bridge
Parameters: Temperature, DO, Fecal Coliform, Conductivity
Special instream monitoring locations or monitoring frequencies:
MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Adequacy of Existing Treatment
Has the facility demonstrated 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) N (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.
