More than 140 facilities across Massachusetts are subject to federal Title V Operating Permit requirements (to learn more, see: About the Massachusetts Operating Permit Program). These facilities are listed alphabetically by community on the table below. Each entry includes:

  • City or Town where the facility is located; and
  • Facility name linked to current Operating Permit (OP) or draft/proposed initial OP or renewal, including public comment period information, if applicable. 

The permit document also provides the facility's Regulated Object (RO) Account Number (a unique identification number MassDEP assigns to a specific regulated waste stream within a facility), Air Quality (AQ) Identification Number (a unique federal identification number assigned to a source of air pollution), and North American Industry Classification System (NAICS) code(s) for primary business(es). Highlighted text in a document indicates amendments or modifications since the operating permit was originally issued.

Note: An Operating Permit remains valid beyond the expiration date indicated and until MassDEP issues a determination provided the facility has submitted a complete and timely application for renewal.
