Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility should choose between new NH3 limits or a toxicity test. Fecal limit changed to 200/100
ml. A narrative limit for temperature should be added to the permits page.

Limits Changes Due To:
Change in 7Q10 data
Change in stream classification
Relocation of discharge
Change in wasteflow
Other (onsite toxicity study, interaction, etc.)
Instream data
New regulations/standards/procedures x Chlorine, fecal, NH3
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.
Parameter(s) Affected
OR
No parameters are water quality limited, but this discharge may affect future allocations.

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) (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.
