Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility discharges to stream with 7Q10/30Q2 = 0. Removal of discharge is recommended in
three years or new limits (page 2) will apply at that time. Facility must submit an engineering
report within 12 months of the effective date of this permit showing no alternative to surface water
discharge. instream monitoring has been done for this facility. If this facility is to be closed
within the year instream monitoring would not be necessary, however, if there is to be continued
discharge for a longer period technical support strongly recommends instream monitoring.

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.

INS TREAM MONITORING REQUIREMENTS
Upstream Location: 50 feet above the discharge point
Downstream Location: 30 feet below the discharge point
Parameters: Temperature, DO, Conductivity, Fecal Coliform
Special instream monitoring locations or monitoring frequencies:
MISCELLANEOUS )i \I FORMATION & 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? 0 4,3 ._i1 C
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.
