Oregon Department of Environmental Quality - Underground Storage Tank Program INTRODUCTION This manual contains guidance on using the Department of Environmental Quality (DEQ, or Department) underground storage tank (UST) cleanup rules. These rules, which include Oregon Administrative Rule (OAR) 340- 122-0205 through 340-122-0360, describe the actions you (the responsible party) must take if petroleum products leak from your regulated UST, and define the procedures and standards for cleaning up the released product. This document contains: • General Information on the UST program including information on reporting releases of petroleum products from USTs, contacting DEQ UST regional staff, permit requirements, cost recovery, etc.; • UST Cleanup Rules with revisions adopted in November, 1998, along with a flowchart, outline and an explanation of each of the rules; • UST Cleanup Guidance on topics such as writing reports, analytical requirements, use of institutional controls, options for handling soil piles, etc.; and • Forms Used for UST Cleanup Projects including copies of the release report form, decommissioning/change-in- service forms, soil matrix checklist and scoresheet; and • References and Additional Guidance containing a list of documents from DEQ, EPA, and other sources, including the internet address where each can be obtained, that you may find useful for UST cleanup projects. Note on Heating Oil Tanks: This UST Cleanup Manual does not apply to underground heating oil tank cleanups except as specified in OAR Chapter 340, Division 177. The Division 177 rules were updated in February 2000 to include provisions for voluntary decommissioning of underground heating oil tanks. In 1999, the Oregon Legislature changed the heating oil tank program significantly by having contractors, rather than DEQ, certify cleanups and decommissionings. If you have questions about heating oil tanks, please leave a message on the UST Program Helpline, 1-800-742-7878 (toll free in Oregon). You may also wish to refer to the heating oil tank rules and guidance documents that can be found on the UST Program web site (see address below). This manual will be updated as new guidance becomes available. We invite you to visit our web site frequently to look for updates and other guidance documents and forms relevant to the UST Cleanup and Compliance Program.
