(State Implementation Plan Revision Advisory Committee)

Clean Air Logo The stakeholder process is important to DEEP as part of the continual refinement of control strategies and regulation development. DEEP often solicits advice from in-state stakeholders through the State Implementation Plan Revision Committee (SIPRAC). SIPRAC is the Air Bureau's standing advisory committee on Connecticut's implementation of the Clean Air Act. Originally established in 1972, SIPRAC was designed to provide an open forum for information exchange and discussion on the Air Bureau's programs, proposed regulations and status of efforts to achieve and maintain air quality standards in the State.

Meeting Schedule

Connecticut SIPRAC meetings are held the second Thursday of every-other month and are listed on the DEEP Calendar of Events. Meetings are typically held in the Gina McCarthy Auditorium at the DEEP Headquarters, 79 Elm St Hartford, CT 06106 and offered through webinar access. However, meetings are now webinar only as access to DEEP’s offices is restricted due to COVID-19.
