What is a Draft Environmental Impact Report (DEIR)?
A DEIR is a state-level document that contains a description and detailed review of a proposed project. It outlines potential benefits and possible adverse environmental effects, possible changes or mitigation that can reduce adverse effects, and possible alternatives or a set of alternatives. It is prepared under regulations established by the Massachusetts Environmental Policy Act administered by the Commonwealth of Massachusetts Executive Office of Energy & Environmental Affairs. After public review of the Draft EIR, any comments are addressed in a Final Environmental Impact Report.
