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

INSTREAM MONITORING REQUIREMENTS
Upstream Location: Southern Railway crossing of Belews Creek and East Belews Creek
Downstream Location: at Dam
Parameters: Temperature
Special instream monitoring locations or monitoring frequencies: Temperature at the Dam recorder

Has the facility demo strated 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 Condition
