Wheelabrator Millbury Facility: FAQ

Where is Wheelabrator Millbury Facility?

Who owns Wheelabrator Millbury Facility?

Project companies are commonly registered as an LLC carrying the plant's name, so a search for "Wheelabrator Millbury Facility LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
