| Objectives | The City of Alturas owns and operates a wastewater collection, treatment, and disposal system, and provides sewerage service within the city limits. The treatment plant is in Section 14, Township 42 North, Range 12 East of the Mt. Diablo Point 001, to the Pit River, a water of the United States, immediately downstream of the confluence of the North and South Forks. The existing treatment system consists of an inlet screen, inlet Parshall flume, grit removal, comminutor, primary clarifier, aerobic sludge digester, fixed bed trickling filter, secondary clarifier, chlorine contact chamber, dechlorination, outlet Pashall flume and outfall structure. The Discharger was issued Cease and Desist (C&D) Order No. R5-2003-0128 on 5 September 2003, which required the City of Alturas to cease and desist discharging waste in violation of Waste Discharge Requirements Order No. 5-00-123 (NPDES No. CA0078921). Specifically the Order required the City to submit a report identifying the selected alternative to either upgrading or replacing the treatment plant. The City has been approved for Small Communities Grant funding and has submitted a plan through their engineering consultant for upgrading the plant which includes: new grinder for headworks, replacement of trickling filter media, replacement of trickling filter pumps and pump drives, addition of secondary clarifier, modification of Pashall flume, new chlorine contact chamber, new concrete sludge drying beds, upgrade of collection system pump stations, slip lining of approximately 2,400 ft of sewer line and modification of chlorination controls. |
