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/l BOD5, 2 mg/l NH3, 6 mg/l dissolved oxygen, and
17 ug/l 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 effluent limitations
within a specified time schedule.

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 BOD5, 2 mg/1 NH3-N, 6 mg/1 DO, and 17 µg/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 effluent limitations within a specified time specified time
schedule.
Central Care has had 1 BOD5 and 2 Fecal coliform violations in the past year.
The facility has had no instances of "no flow" up or downstream. D.O.'s are greater than 5 mg/l.

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.
X.
X_ No parameters are water quality limited, but this discharge may affect future allocations.

INSTREAM MONITORING REQUIREMENTS
Upstream Location: at least 100 ft upstream

MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Adequacy of Existing Treatment
Has the facility dem9a�gtrated the ability to meet the proposed ne�v limits with existing tre tment
facilities? Yes l/ No �ssu�e'
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? _N (Y or N) If yes, explain with attachments.
