MEPA Environmental Review

The Massachusetts Environmental Policy Act (MEPArequires state agencies to study the environmental consequences of their actions (such as issuing a permit) and take measures to avoid, minimize, and/or mitigate any environmental damage. MEPA review occurs in advance of permitting but is not a permitting process itself.

MEPA requires an analysis of the overall environmental consequences of the project as well as a public review. The MEPA environmental review will include a description of project alternatives and an analysis of the project’s impacts on air quality, noise, traffic, greenhouse gas, resiliency, and other subjects as directed by the MEPA Office.

The MEPA process itself does not determine whether a project is environmentally beneficial or whether a particular permit should be issued. Those decisions are left to the permitting agencies.
