    If the UST system is regulated through another program, the developer should consult the agency responsible for regulated the program. If the UST system is completely exempt, the developer does not need to complete this process.

    18-WA-a.4 to 18-WA-a.5 – Has the WSDE Delegated the UST Program Responsibilities to a Qualified City, Town or County

    The WSDE has the authority and encourages the delegation of the UST program to a qualified city, town, or county. WAC 173-360-500. In addition, a fire protection district or political subdivision may enter into an agreement with the city, town, or county to assume all or a portion of the delegated responsibilities. If the WSDE has delegated the UST program to a qualified local authority, the developer should consult the appropriate local authority for the UST process.

    18-WA-a.6 – Underground Storage Tank 30-Day Notice Form

    To apply for a UST permit for a new UST system or a previously unreported UST system, the developer must complete a 30-Day Notice Form and submit the form with payment of the applicable annual fee at least thirty days and not more than ninety days before installing the UST system. WAC 173-360-200. The developer may use the form to provide notice for more than one UST system at the same site, but UST systems installed at separate sites must file a separate notice for each site. The 30-Day Notice Form includes:

    • Information about the owner of the UST system;
    • Information about the site of the UST system;
    • Information about the UST system, including substance stored, capacity, and project start date; and
    • Information about the service provider(s) installing the UST system.

    Developers seeking to install a UST system sooner than the 30 day requirement should contact the WSDE for a waiver.

    18-WA-a.7 – Review 30-Day Notice Form

    The WSDE will review the 30-Day Notice Form for compliance with WAC 173-360-130. UST systems are eligible for a UST permit if the following conditions are met:

    • The UST is not known by the owner or operator to be leaking; and
    • All annual state tank fees and local environmentally sensitive area tank fees have been remitted.

    18-WA-a.8 to 18-WA-a.9 – Does the WSDE approve the 30-Day Notice Form

    If the WSDE approves the 30-Day Notice Form, the WSDE issues an Underground Storage Tank System Permit, which allows for the developer to install the UST. If the 30-Day Notice Form lacks required information, the WSDE will request the additional information.

    18-WA-a.10 – Begin UST System Installation

    Within 90 days after receiving the Underground Storage Tank System Permit the developer must have a Washington licensed UST installer install the UST system. The date stamped on the approved 30-Day Notice Form constitutes the beginning of the 90 day period in which the installation must begin.

    18-WA-a.11 – Business License and UST Addendum

    The developer must complete the Business License Application and Underground Storage Tank Addendum and submit the forms to the Washington State Department of Revenue (WSDR). The developer must complete the Business License Application regardless if the developer already holds a business license. If the developer holds a business license, the application will serve the purpose of adding an endorsement to the current business license. In addition, the developer must complete the Underground Storage Tank Addendum and submit the form upon installation of the UST system. The Underground Storage Tank Addendum includes an installer certification section, whereby the certified UST installer must sign the form certifying that the installation of the new UST system listed on the form was in compliance with all applicable regulations, codes, and standards and that a certified supervisor was on site during all required installation activities.
