Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
This permit should be renewed with a fecal coliform limit of 200/100m1 and a chlorine limit of 28
µg/l. Facility does not exist and does not have an ATC. Ammonia limits should also be put in the
permit.

Limits Changes Due To: Parameter(s) Affected
Change in 7Q10 data
Change in stream classification
Relocation of discharge
Change in wasteflow
Other (ammonia toxicity) x NH3
Instream data
New regulations/standards/procedures x fecal
New facility information
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

MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Adequacy of Existing Treatment IPA -Pa c )'hj h J it o t- 6 ee r 4 0: f
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) (Y or N)
(If yes, then attach schematic, toxics spreadsheet, copy of model, or, if not modeled, then old
