What is MEPA?

Established as state law in the late 1970s, the Massachusetts Environmental Policy Act (MEPA) is a uniform system of environmental impact review with the intent to reduce the potential for harm to the environment from certain development and transportation projects.

The intent of MEPA review is to inform project applicants and state agencies of potential adverse environmental impacts while a proposal is still in the planning stages. The developer and all relevant state agencies are required to identify any aspects of a proposed project that may necessitate additional description or analysis prior to the issuance of a Certificate and Section 61 Findings by the Executive Office of Energy and Environmental Affairs.

MEPA also requires developing enforceable mitigation commitments, which will become permit conditions for the project. As part of the public review process, MAPC submits comment letters for projects considered to be of significant regional impact.
