• Welcome to the MEPA Website

    Welcome to the new Massachusetts Environmental Policy Act (MEPA) Website. We hope you find that our new homepage is easy to navigate in order to obtain information on projects that are either currently under review by the MEPA Office or have been reviewed in the past. In the coming months, we will be introducing an electronic filing system for the submission of environmental review documents, electronic submission of comments for projects under review, and on-line review of project files.
