AB-1313: Statewide Stormwater Permit Rules

This bill requires the state water board to create a single permit rule for large commercial, industrial, and institutional properties that manage stormwater runoff.

What This Bill Does

  • Requires the State Water Resources Control Board to make specific findings before creating a new statewide order.
  • Establishes rules for facilities with at least 5 acres of impervious surface that are significant contributors of pollutants to federally protected waters, as determined by the state board.
  • Regulates stormwater and authorized nonstormwater discharges from these properties.
  • Sets a deadline to publish a draft rule for public comment by December 31, 2028, or within 18 months after a specified statewide permit is reissued.
  • Requires the board to establish rules for agreements between property owners and local cities to capture and use stormwater offsite.

Who It Names or Affects

  • The State Water Resources Control Board
  • Commercial properties with at least 5 acres of impervious surface that are significant contributors of pollutants
  • Industrial facilities meeting the size requirement that are significant contributors of pollutants
  • Institutional sites meeting the size requirement that are significant contributors of pollutants

Terms To Know

NPDES order
A permit rule under federal and state law that controls what waste can be discharged into water.
Impervious surface
Hard ground like concrete or asphalt where rain cannot soak in, causing it to run off as stormwater.

Limits and Unknowns

  • The bill does not list the specific pollutants that will be regulated.
  • It is unclear which properties are considered 'significant contributors' until the state board makes a determination.
  • The final rules for offsite agreements depend on future negotiations between property owners and local cities.
