Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
The facility discharges into a stream with 7Q10/30Q2=0 cfs. Removal of the discharge will be
required if a more environmentally sound alternative is available. An engineering report evaluating
alternatives to discharge is due 180 days prior to permit expiration along with the permit renewal
application. As part of the report, the cost of constructing a treatment facility to meet limits of 5
mg/1 BODS, 2 mg/1 NH3, 6 mg/1 dissolved oxygen, and 17 ug/1 chlorine must also be included if
there are no alternatives to a surface discharge. Upon review of the results of the engineering
report, the Division may reopen and modify this NPDES permit to require removal of the
discharge, modified treatment designs, and/or revised efflue t li��tatigns within a specified time
schedule. Fecal limit should be changed to 200/100 ml. /" `r 51,70t40.7e /e4_,e-rckK o/ci47?1 .

Limits Changes Due To: Parameter(s) Affected
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 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
No parameters are water quality limited, but this discharge may affect future allocations.

MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Adequacy of Existing Treatment
Has the facility demgrfstrated the ability to meet the proposed new limits with existing treatment
facilities? Yes r 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?
