Comparison: State vs. Federal

Rules. California requires dischargers to comply with both the federal technology-based effluent limitations and the state's waste discharge requirements. Dischargers should follow the federal regulations to request a variance from technology-based effluent limitations or pretreatment standards. California's waste discharge requirements are determined on a case-by-case basis. For more information about the federal requirements, see the national section WASTEWATER VARIANCES.

The federal program, the National Pollutant Discharge Elimination System (NPDES), is also implemented by the RWQCBs, subject to EPA review. See the state section NPDES PERMITS for more information.

Administration and enforcement. Cal/EPA's SWRCB shares responsibility with California's RWQCBs for the administration and enforcement of the state's wastewater discharge regulations, including for NPDES permits. The RWQCBs are responsible for the day-to-day operation of the state's discharge permitting program, including requests for any revisions of wastewater discharge requirements.
