Bill > AB1313

This bill requires the State Water Resources Control Board to establish a statewide National Pollutant Discharge Elimination System (NPDES) permit for commercial, industrial, and institutional properties with 5 or more acres of impervious surface (like parking lots, shopping centers, and industrial work areas). The bill recognizes that urban stormwater runoff is a major source of water pollution, containing harmful pollutants such as heavy metals, sediments, and nutrients that can damage water quality and aquatic habitats. The state board must publish a draft of this statewide order for public comment by December 31, 2028, or 18 months after the reissuance of a specific existing industrial stormwater permit. The bill also requires the board to establish rules for offsite compliance agreements between permittees and local municipalities, allowing for collaborative stormwater capture and use strategies. The NPDES order must provide multiple compliance options for businesses, including incentives for green infrastructure and onsite or offsite stormwater management. Importantly, the bill aims to streamline water quality regulation by ensuring that a facility is subject to only one stormwater NPDES order, with all applicable effluent limitations incorporated into this single, comprehensive permit.
