Supplemental Environmental Projects

  • General Guidance
    • The State Water Resources Control Board (State Water Board), or Regional Water Boards, may allow a discharger to satisfy part of the monetary assessment imposed in an administrative civil liability (ACL) order by completing or funding one or more Supplemental Environmental Projects (SEPs). The State Water Board adopted a policy addressing SEPs on 3 February 2009 (SEP Policy). Interested parties can submit proposals for consideration by following the guidance provided in the SEP Policy. All projects submitted for consideration are subject to staff's review and a 30 day public comment period before they are formally accepted for inclusion on the list.

    • The State Water Board's SEP Policy supersedes the SEP Criteria adopted by the Central Valley Regional Water Quality Control Board (Central Valley Water Board) on 5 December 2008. Although the Central Valley Water Board's SEP Criteria is no longer the governing document, it has instructions for proposing projects that can still be used by interested parties to assist in developing a proposal.
