a. No discharge to waters of the state is permitted. All wastewater must receive a minimum of secondary treatment by facultative lagoons. Effluent disposal must consist of infiltration and evaporation through Outfall 001- infiltration cell, and must be managed and disposed of in a manner that will prevent a violation of the DEQ's Groundwater Quality Protection Rules (OAR 340-040).

b. The system may accept the following wastes generated within the boundaries of the collection system: domestic wastewaters entering the collection system or generated on National Forest System lands and hauled from National Forest System facilities within the boundary of the Umpqua National Forest, RV dump station-holding tank waste, and vault toilet waste.

c. The permittee may not accept hauled wastes which are generated from outside the collection system including but not limited to wastewater solids from another treatment facility, domestic septage and portable/chemical toilet wastes which are not generated on National Forest System facilities within the boundary of the Umpqua National Forest, grease trap wastes, landfill leachate, groundwater remediation wastewater, and commercial or industrial wastewater unless DEQ has approved a hauled waste management plan and given the permittee written approval.

d. No activities must be conducted that could cause an adverse impact on existing or potential beneficial uses of groundwater. All wastewater and process-related residuals must be managed and disposed in a manner that will prevent a violation of the Groundwater Quality Protection Rules (OAR 340-040).

Outfall 002 - Infiltration Cell Overflow

a. Overflows to waters of the state are prohibited. No discharge is allowed except in the case of overflow caused by excessive snow melt. Overflow from stand pipe at Outfall 002 shall be reported to DEQ on the monthly DEQ-approved discharge monitoring reports (DMRs).
