Industrial Pretreatment Regulation
The Pretreatment Program includes Industrial Waste Inspectors, Laboratory Chemists and Field Technicians, whose primary goal is the protection of the treatment plant and sanitary sewer colletion system from industrial waste. By regulating the disposal of industrial wastewater into the sanitary sewer, the Pretreatment Program seeks to prevent the introduction of pollutants that could interfere with the operation of the Plant, cause damage to the sewer system, compromise public health or worker safety, or pass through the Plant to the Bay.
Industrial and commercial facilities are regulated through discharge permits, Best Management Practices (BMPs), and routine inspection and monitoring. On average, the Pretreatment Program has 50 active industrial wastewater discharge permits issued to Significant Industrial Users (SIUs). Discharge Permits contain specific requirements and limits for the concentration of pollutants in wastewater discharges. Additionally, hundreds of commercial facilities are regulated through the application of BMPs tailored to specific activities commonly found in commercial businesses. When implemented, the BMPs reduce or eliminate the introduction of pollutants into the sanitary sewer.
