The Leaking Underground Storage Tank Cleanup Program provides oversight for cleanup activities at UST sites with recorded releases.
If you need to report a LUST incident, you MUST complete the 20-Day Report Form within the first 20-days from the known release, followed by a 45-Day report.
You will need to submit a Cost Recovery Agreement in the Your DEQ Online Portal.
Failure to complete these steps will result in referral for enforcement actions.
Cost Recovery Agreement
Cost Recovery Agreements are submitted through YDO. More information can be found on the DEQ Cost Recovery Agreement page.
LUST Reports - Responsible Party Submittals
These reports may be submitted by the Responsible Party directly or by a consultant on behalf of the responsible party. More information on is available in the LUST Cleanup Manual and the LUST Info Packet.
After you have stopped the release, taken all emergency measures, and reported the release to DEQ, you must:
- Remove product from the tank and piping as needed;
- Keep product from spreading;
- Take initial soil and/or water samples;
- Sample for vapors or fumes if necessary;
- Prevent any hazards that may result from the removal of product, contaminated soils and backfill; and
- Check whether free product is present. If free product is found, you must remove as much of it as possible, following OAR 340-122-0235.
After taking the above measures, submit a report summarizing these actions to the appropriate DEQ regional office. This report is due within twenty (20) days after the release has been confirmed, or within another reasonable period of time approved by DEQ.
Within forty-five (45) days after confirming the release, or within another reasonable period of time approved by DEQ, you must submit a report summarizing the site characterization. Include a description of the nature and quantity of the release as well as how much product was recovered. Also include a detailed site plan drawn to scale identifying adjacent properties, buildings, tanks and excavations, and all groundwater wells. Data from all soil and groundwater samples collected during the initial site check and the site characterization should also be included in this report. There is not a form for this report, the report is submitted to your Cleanup Project Manager.
Vapor Intrusion Guidance
The 2025 revision is the first update since DEQ's 2010 Vapor Intrusion Guidance. It includes substantial revisions to align with current science, standards of practice, and the U.S. Environmental Protection Agency's vapor intrusion screening levels. The revisions reflect internal and external review and feedback, including listening sessions and an informal public review period from March to June 2024. The revised guidance will improve DEQ's ability to protect people in Oregon, especially those most at risk, from health risks associated with vapor intrusion.
Please refer to the Vapor Intrusion Guidance Page for more information.
