Massachusetts Environmental Policy Act Office (MEPA)

The MEPA Office is part of the Executive Office of Energy and Environmental Affairs (EEA).  We provide meaningful opportunities for public review of the potential environmental impacts of projects for which agency action is required.  We serve the general public, state agencies, municipalities, and project proponents.

MEPA does not discriminate on the basis of race, color, national origin, disability, age, sex, income, ethnicity, class, handicap, religious creed or belief, gender identity, sexual orientation, genetic information, English language proficiency or ancestry in administration of its programs or activities. 

On behalf of the Secretary of EEA, the MEPA Office conducts reviews of environmental impacts of development projects and other activities that require one or more agency actions. The MEPA Office is responsible for the day-to-day administration of the MEPA review process, including to:

• solicit comments from the general public and reviewing agencies
• represent the Secretary at public consultation session on projects
• coordinate project review with proponents, consultants, and interested agencies and citizens, and
• make recommendations to the Secretary regarding the adequacy of environmental documentation submitted for a project.
