California AB1313 mandates stormwater permits for commercial, industrial, and institutional sites with significant impervious surfaces.

California AB1313 requires the State Water Resources Control Board to establish a statewide National Pollutant Discharge Elimination System (NPDES) order for commercial, industrial, and institutional sites with five or more acres of impervious surfaces. This order aims to address water quality impairments caused by stormwater discharges, which contain elevated levels of pollutants such as lead, copper, zinc, and sediments. The legislation mandates multiple compliance options, including incentivizing green infrastructure for stormwater capture and use.
