Required by MassDEP under the 1998 Rule, these are plans that describe how municipal waste combustor operators will prevent discarded items that contain mercury from entering their facilities.

Material Separation Plans (MSPs) must be submitted to MassDEP at intervals the agency designates. Each facility develops its own plan in consultation with its commercial, industrial and municipal customers. Draft plans are submitted to MassDEP for review. The agency solicits public comment on these documents before approving them, attaching additional conditions, if necessary. Facilities then must implement their Material Separation Plans and submit annual progress reports to MassDEP.
