Notice of project change
MassDOT filed a Notice of Project Change (NPC) with the Massachusetts Environmental Policy Act (MEPA) Office on August 1, 2022. The purpose of the NPC is to update the status of the Project in the state environmental review process to align with the advancements made to the project since publication of the 2017 Draft Environmental Impact Report (EIR). The NPC provides a preliminary analysis of environmental effects associated with the Throat Area options. It also responds to the Secretary's Certificate and public comments received on the 2017 Draft EIR.
The NPC is available to download from the MEPA database. Search using the project file #15278
