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.
