Under MassDEP's Waste Site Cleanup Program, the cleanup of oil and hazardous material disposal sites may consider the current and likely future use of the property. If a cleanup is based on anything less than "unrestricted use", then the closure must include an enforceable Activity and Use Limitation ("AUL") that specifies the allowable and prohibited use of the property.
