    The Fresno Metropolitan Flood Control District (FMFCD) operates the Regional Stormwater Management Basin System, which consists of storm drains, retention/detention basins, pump stations, and outfalls, to handle stormwater runoff and non-stormwater discharges in the FMFCD service area, which include the City of Fresno, the City of Clovis and parts of the County of Fresno.


    On May 31, 2013, the Central Valley Regional Water Quality Control Board (Regional Water Board) issued a National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) Permit (CAS0083500, Order No. R5-2013-0080), referred to as the MS4 Permit, which regulates stormwater and non-stormwater discharges from the MS4 Permit area to Waters of the United States.


    As part of the MS4 Permit, each Permittee (FMFCD, City of Fresno, City of Clovis, County of Fresno and CSU Fresno) is required to incorporate into its CEQA process, procedures for considering potential stormwater quality impacts and providing for appropriate mitigation when preparing and reviewing CEQA documents.


    The procedures require consideration of the following:

    • Potential impact of project construction on stormwater runoff.
    • Potential impact of project post-construction activity on stormwater runoff.
    • Potential for discharge of stormwater from areas from material storage, vehicle or equipment fueling, vehicle or equipment maintenance (including washing), waste handling, hazardous materials handling or storage, delivery areas or loading docks, or other outdoor work areas.
    • Potential for discharge of stormwater to impair the beneficial uses of the receiving waters or areas that provide water quality benefit.
    • Potential for the discharge of stormwater to cause significant harm on the biological integrity of the waterways and water bodies.
    • Potential for significant changes in the flow velocity or volume of stormwater runoff that can cause environmental harm.
    • Potential for significant increases in erosion of the project site or surrounding areas.


    FMFCD has prepared the 2016 Guidance for
    Addressing Stormwater Quality for CEQA Review
    to comply with these requirements. Use this document when you are reviewing and preparing CEQA documents.


    If you have any questions feel free to contact me. Thank you.
