Stormwater permits are a type of TPDES general water quality permit for stormwater runoff from construction sites, industrial facilities, and publicly owned and operated storm sewers. There are several types of general permits:

A Stormwater Pollution Prevention Plan (SWPPP) is a site-specific, written document that Identifies potential sources of stormwater pollution, describes practices to reduce pollutants in stormwater discharges and identifies procedures the operator will implement to comply with the terms and conditions of a stormwater general permit.
