Petroleum-Contaminated Soil Treatment

If you are treating petroleum contaminated soil from an UST release on your property (on-site) or beyond your property's boundary (off-site), you must obtain a Solid Waste Letter of Authorization (SWLA) permit from DEQ. The SWLA permit application requires a Soil Treatment Plan. Off-site treatment also requires a Land Use Compatibility Statement.

Questions, call DEQ at (503) 229-5733 (toll free in Oregon at 1-800-742-7878), or check out the Underground Storage Tank Program Web site.
