Waste Discharge Program
- Municipal discharges include the discharge of waste water from municipal or quasi-municipal public sewer systems.
- Industrial discharges include the discharge of process water water, cooling water and other contaminated waters from industrial or commercial sources.
The wastewater discharge law requires that a license be obtained for the discharge of pollutants to a stream, river, wetland, or lake of the state, or to the ocean. Typical discharges include sanitary waste water and process water from industrial or commercial activities. A license is also required for the discharge of pollutants to groundwater, except for subsurface disposal systems installed under the State Plumbing Code.
