UST Program - Petitions Regarding UST Cleanup


A petition is a request from an aggrieved person for the State Water Board to review any action or failure to act by a regulatory agency that may be improper or inappropriate. There are different filing procedures depending on which type of petition is most appropriate to file. Where should petitions be sent?

  1. Petitions for Closure of UST Case (RWQCB or LOP Agency)
    Any underground storage tank or residential tank owner or operator or other responsible party who believes that corrective action has been satisfactorily implemented, but who has not been granted closure, may petition the State Water Board for review of the case.
  • For instructions on how to file a closure petition, link to our Closure Petition Fact Sheet.
  • To view a list of State Water Board closure petition decisions, link to Closure Orders.
  • Additional details regarding the closure petition process can be found in Article 6 of Chapter 18 of the Petroleum Underground Storage Tank Cleanup Fund Regulations.
Closure petitions should be mailed, faxed or filed in person to:

Although not required for you to file a closure petition, the submittal of the following information is helpful:

  • Information about repair, removal and installation of USTs and associated components.
  • Information on the water quality specific to the site and the surrounding area.
  • A narrative and graphic representation of site conditions which explain the dynamics of the local hydrogeology and contaminant distribution and migration.
  1. Non-Closure Petitions Involving Regional Board Oversight of UST Cases
    For matters not involving closure, an aggrieved person may petition the State Water Board in matters involving a Regional Board’s actions or failure to act. For more nformation and details about how to file one of these water quality petitions, review information on the State Board's water quality petitions web page.

  2. Non-closure Petitions Involving Local Oversight Program (LOP) Agency Oversight of UST Cases
    For matters not involving closure, an aggrieved person may petition the State Water Board in matters involving LOP agency’s actions or failure to act. There are 20 LOP Agencies. For more information and details about how to file one of these petitions, review Resolution No. 88-23 for filing LOP petitions.

    Non-closure Petitions involving Local Oversight Program (LOP) Agency Oversight of UST Cases should be mailed, faxed or filed in person to:

      State Water Resources Control Board
      Office of Chief Counsel
      1001 "I" Street, 22nd Floor

      FAX: (916) 341-5199
      ATTN: Lori Brock, Staff Counsel (916) 341-5185

    Actions or decisions made by local agencies not participating in the Local Oversight Program are not subject to review by the State Water Board.
