Note: Maine DEP uses a decision tree approach to establish remediation standards. Four categories of sites are Baseline 1 (BL-1), Baseline 2 (BL-2), Intermediate (IN), and Stringent (ST), depending upon geologic vulnerability of site and availability of public water. * Remediation of groundwater is required at ST sites only. The State of Maine plans to reassess its Maximum Exposure Guidelines (MEGs) on which the cleanup levels for Total Gasoline and Total Fuel Oil are based.

A list of approved instruments and their set points is available from DEP. ** ST and IN sites only; BL-1 sites require only removal of free product and product-saturated soils. BL-2 sites may be remediated to 500-1000mg/kg, measured by field/headspace *** ST and IN sites only; BL-1 sites require only removal of free product and product-saturated soils. BL-2 sites may be cleaned to 200-400mg/kg, measured by field/headspace Contact: Fred Lavallee, Maine Department of Environmental Protection, 207-287-7677 E-mail: [email protected]
