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 permit from DEQ. The SWLA permit application requires a Soil Treatment Plan. Off-site treatment also requires a Land Use Compatibility Statement.
