Massachusetts Environmental Policy Act Office (MEPA)

The MEPA review process provides meaningful opportunities for public review of potential environmental impacts of certain projects for which certain actions by state agencies are required. It requires state agencies to study the environmental impacts of projects requiring state permitting, financial assistance or land disposition, and to use all feasible measures to avoid, minimize, and mitigate damage to the environment or, to the extent damage to the environment cannot be avoided, to minimize and mitigate damage to the environment to the maximum extent practicable.

Who we serve

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 state agency action is required.  We serve the general public, state agencies, municipalities, and project proponents.


Until further notice, the MEPA Office will operate remotely and project submittals and other correspondence will continue to be accepted during this time. Additional information regarding submission of MEPA filings, site visits, pre-filing meetings, and other inquiries is provided below.

Submitting MEPA Filings (revised 5/20)

In light of current events, electronic submittals to both the MEPA Office and other state agencies will be permitted. Electronic submittals that are sent to by 5:00 PM on the submittal deadline will be accepted for publication in the next edition of the Environmental Monitor.  Please note that a filing will not be published in the Environmental Monitor unless it is complete upon submission.

An electronic copy of the complete submittal (including all attachments) should be sent concurrently to the MEPA Office ( and to the required distribution list.  Please use the following Electronic Distribution List (revised 12/09/2020) for state agencies. To facilitate review, you may be requested to provide a courtesy hard copy of a project submittal to the MEPA Analyst and/or may be requested to provide a hard copy to the MEPA Office for inclusion in the project file at a future date.  

The electronic submittal should be sent to MEPA and state agencies using a file share service. The entire electronic submittal, including appendices and site plans, must be accessible and legible. Additionally, please ensure the submittal meets the following criteria:

  • The link to download the electronic submittal must be accessible by others (not just the direct recipient).
  • All electronic submittals over 50 pages must include bookmarks or an electronic table of contents that provides direct links to each of the sections and appendices. Alternatively, each section and appendix should be provided as a separate file.
  • Permissions must be set to allow for the electronic document to be downloaded from a file sharing website without requiring an individual to create an account. This provision does not apply to secure FTP file sharing websites.

Due to volume restrictions of the email system, please do not directly send the electronic submittal as a PDF.  Please be prepared to provide copies of electronic submittals in an alternative format (such as reduced file sizes or zip files) to anyone requesting to receive them.

Site Visits

All site visits will be conducted remotely until further notice. The MEPA Office will minimize remote site visits for projects, but will continue to hold remote site visits for larger projects or those garnering public attention. The Proponent will be expected to describe the site and share existing conditions photos and site plans in addition to providing an overview of the proposed project.  The Proponent will be responsible for providing a call-in/weblink to host the remote consultation session with the capability to share files (i.e., “screen share” capability) and host at least 25 participants through a telephonic or video dial-in feature. If the Proponent is unable to host a remote site visit, it should consult with the MEPA Office about alternative methods.

Information regarding the consultation session (including the date/time, call-in number, and weblink) will be posted in the Site Visit section of the Environmental Monitor.
