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. 3 MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS A_dtuacv 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? n *Instream monitoring for fecal coliform Upstream site:100 ft upstream of outfall Downstream site:100 ft, downstream of outfall 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?
