SHASTA MILL WWTP - Pulp and Paper Wastewater Treatment Plant in Anderson, California

SHASTA MILL WWTP is a pulp and paper wastewater treatment plant located in Anderson, Shasta County, California. The facility is operational and treats process wastewater from the associated Shasta Mill, a pulp and paper production site. As a sector-specific treatment plant, it handles effluents typical of the pulp and paper industry, including organic loads and process chemicals. The plant operates under the regulatory framework of the United States Environmental Protection Agency (EPA), which enforces the Clean Water Act (CWA) through National Pollutant Discharge Elimination System (NPDES) permits. These permits set effluent limits for parameters such as biochemical oxygen demand (BOD), total suspended solids (TSS), and pH. Additionally, the facility may be subject to the Clean Air Act (CAA) for emissions from treatment processes and Resource Conservation and Recovery Act (RCRA) for sludge management. Pulp and paper mills are significant water users and wastewater generators. The SHASTA MILL WWTP plays a critical role in treating process water before discharge, reducing environmental impact on local water bodies. The plant's location in Anderson, California, places it within a region with diverse industrial activity and environmental oversight by state and federal agencies.

The plant is situated in Shasta County, California, an area with Mediterranean climate and proximity to the Sacramento River watershed. Pulp and paper wastewater treatment involves managing high organic loads, suspended solids, and potential chlorinated compounds. The facility's discharge must comply with stringent water quality standards to protect aquatic life and downstream uses. Community proximity to the plant necessitates effective odor and emission control measures.
