Ready to File?

This page contains useful resources when filing with the MEPA Office.

To assist you in preparing your MEPA filing, the MEPA office has created the guides below for filing an Environmental Notification Form (ENF), Notice of Project Change (NPC) and Environmental Impact Report (EIR). You can also find a link to the MEPA filing forms, schedule a pre-filing meeting, and view MEPA Regulations and MEPA Policies and Guidance on this page. A link to the MEPA Environmental Justice page with resources for MEPA filers is also found below.

MEPA Online Filing (Required)

You must now file your ENF, NPC and EIR online. Effective July 1, 2025, online filing is mandatory for the ENF, NPC and EIR. Filings made by email will be rejected; however, online distribution of filings is still required. If you need assistance with using our online system, you can send an email to mepa@mass.gov.
