Pollution Prevention - Permission to Discharge
California's Water Boards administer the National Pollutant Discharge Elimination System (NPDES) program, managing point source wastewater discharges to surface waters in the State of California.
Discharge permits protect drinking water supplies as per the national Clean Water Act and in California, the Porter-Cologne Water Quality Control Act.
From the California Water Boards, "Wastewater is water that contains waste from residential, commercial, and industrial processes. Municipal wastewater contains sewage, gray water (e.g., water from sinks and showers), and sometimes industrial wastewater from small industries. Large industries, such as refineries, also generate wastewater and discharge separately from municipal wastewater. Some wastewater discharges are exempt from federal NPDES requirements, but California law may still apply. For example, under California law, we require waste discharge requirements (WDRs) for discharges to land that could potentially affect groundwater. Therefore, we issue WDRs for wastewater recycled for reuse and wastewater discharged to land, including on-site treatment systems."
WTCal.us reports matters concerning discharges potentially impacting drinking water sources alongside flood and bluegreen algae blooms by watershed area and drainage basin. Flooding carries land-applied contaminants to the waterways, as such these events are plotted together as observed. Understanding the National Pollutant Discharge Elimination System (NPDES), Land Application System (LAS), Pretreatment permits, Sludge Management Plans, and/or Industrial Pretreatment Programs is an important facet of the work.
When discharge permits are not followed, whether intentionally or accidentally, the US EPA can step into an enforcement role to assist the State. See an example of a metal finishing company in violation of the Clean Water Act by way of breaching the discharge permit terms, here.
