MassDEP

Comprehensive Plan Approval and PSD

The Massachusetts Department of Environmental Protection (MassDEP) issues a written Major Comprehensive Plan Approval (MCPA) once it has determined that the upgraded plant will comply with state and federal air quality regulations and state noise policy.

In addition, MassDEP administers the federal Prevention of Significant Deterioration (PSD) permitting program, which ensures that the project complies with EPA New Source Review (NSR) regulations (as part of the 1977 Clean Air Act Amendments).

The MassDEP process includes a period of public review and comment. Information about the MassDEP public review meeting dates and locations are provided below and will be posted in local news publications.
