Toxics Cleanup Program

Underground Storage Tanks (USTs)

Ecology currently regulates more than 11,000 active tanks on approximately 4,000 different properties, including gas stations, industries, commercial properties, and governmental entities.  The agency works to ensure these tanks are installed, managed, and monitored in a manner that prevents releases into the environment.  To do so, the agency conducts compliance inspections on about 800 sites per year (most sites have multiple tanks) and provides technical assistance to tank owners.

Federal Energy Policy Act of 2005


The United States Congress (House and Senate) passed and President Bush signed into law the Energy Policy Act of 2005.  Among many other things, this federal law placed new underground storage tanks (USTs) requirements on the U.S. Environmental Protection Agency and/or the states.  Some of the new requirements include: conducting routine compliance inspections of USTs; developing an UST operator training program; implementing a delivery prohibition process; requiring secondary containment  for new or replacement UST components (double walled tanks and piping and under dispenser containment sumps; and providing reports to EPA and the public.

Two New UST Cathodic Protection Evaluation Checklists;

  1. Galvanic Cathodic Protection Evaluation Checklist ECY 070-339 (October 2008)
  2. Impressed Current Cathodic Protection Evaluation Checklist  ECY 070-340 (December 2008)

These Microsoft WORD files provide two new Cathodic Protection Evaluation Checklists for your use.  These checklists are for the use of UST Cathodic Protection (CP) Service Providers who test the adequacy of existing systems (also known as CP Testers) and for those who design the retrofit and repair of existing systems (also known as CP experts).  Ecology recommends service providers begin using these two new forms rather than the single existing checklist from 2003, found at: http://www.ecy.wa.gov/biblio/ecy07070.html.  Ecology will begin incorporating the use of the new Cathodic Protection Checklists starting in November 2008.  Following the six month incorporation period, the old checklist will no longer be accepted by Ecology.  If you have questions or comments about these two new checklists, please contact Arthur Buchan with Ecology’s Northwest Regional Office at abuc461@ecy.wa.gov or at (425)649-7149.  Please note that these forms are “fillable” on line, and the forms can be downloaded for future use.  Additionally they are password protected to prevent form changes by the user.  If the form is filled out electronically, it must be printed, signed, and mailed to Ecology.  If you would prefer triplicate paper copies of these forms, please send a request with your contact information to Ann McNeely at amcn461@ecy.wa.gov.  Of course, you can also print the form, complete the checklist with a pen, sign it, make copies and mail the original to Department of Ecology, Toxics Cleanup Program, P O Box 47600, Olympia, WA  98504-7600. 

Inspection Overview (.pdf 1,128 kb) Updated  May 12, 2004

This Adobe Acrobat pdf file provides an overview in words and pictures of what Ecology inspectors look for during UST inspections. Also serves as a user-friendly overview of UST requirements. This overview was created in powerpoint, and then converted to pdf format for easy accessibility.

Detailed UST Site Inspection Guidance Document Added
October 2004 (.pdf)

This guidance document is intended to provide information needed by underground storage tank (UST) owners, tank service providers, and government agencies involved in preventing releases from USTs. This document explains each item on the attached UST Site Inspection checklist, which is used by inspectors, while conducting UST site inspections.

Electronic Data

  • Facility Site on the Web
    The Facility/Site Identification System contains key information for each facility/site that is currently, or has been, of interest to Ecology, including underground storage tanks (UST) and leaking underground storage tanks (LUST) .  The system allows users to dynamically query the database based on specific criteria (e.g. county, city, facility site, site id, Standard Industrial Classification codes, etc.).
