| Objectives | The Discharger owns and operates a sanitary sewer collection system and the Facility, a publicly owned treatment works (POTW). To comply with the CDO, the Facility upgraded the wastewater treatment system descrived in Order No. 5-01-180 with an interim tertiary treatment system. The interim tertiary treatment system consists of headworks with a parshall flume and manual bar screen, two mechanically aerated treatment ponds in series, chlorination, coagulation, sedimentatin, filtration, dechlorination, and a 69 million gallon storage reservoir. The Facility ceased discharging wastewater to the land. Domestic wastewater and collected seepage from the storage reservoir is trated in the interim tertiary treatment system and discharged through Discharge Point No. 001 to unnamed tributary to Smuthers Ravine, a water of the United States and a tributary to the North Folk of the American River via Bunch Canyon, within the Sacramento River Watershed. |
