Short Description

A receiving water study was conducted on October 18-19, 1988, for the Okanogan Wastewater Treatment Plant (WTP) which discharges to the Okanogan River. Thorough, rapid mixing was observed. Fecal coliform bacteria exceeded the water quality standard both above and below the WTP following a brief rain event on October 18 (0.2 inch). Water quality close to the outfall was much improved compared to 1977 in terms of total residual chlorine (TRC), specific conductance, and temperature. Recommendations include establishing a dilution zone 300 feet or 10% of the length of the dilution zone, and establishing a permit limit for TRC of 0.7 mg/L.
