Emergency Burn Ban In Effect 10/26/24 - An emergency burn ban is now in effect for all Connecticut State Parks, Forests, and Wildlife Management areas, prohibiting the use of all outdoor grills, firepits, and campfires, and the kindling and use of flame outdoors. DEEP and local agencies are working to contain several active fires across the state. Please avoid all affected State Parks and Forests, as well as the blue-blazed Mattabesett Trail. The Enduro Trail in Voluntown and portions of North Stonington within the Pachaug State Forest are closed at this time. Please note that today's forest fire danger report remains at an 'extreme' level. More information about the current fire danger, burn ban and recommended safety measures can be found here

Revision to
Connecticut's State Implementation Plan
8-Hour Ozone Attainment Demonstration
(for the 1997 NAAQS)
  
This page presents the Connecticut Department of Energy and Environmental Protection’s (CT DEEP) air quality state implementation plan (SIP) revision for attaining the 1997 federal 8-hour National Ambient Air Quality Standard (NAAQS) for ground-level ozone, and related DEEP/EPA correspondence. The plan describes the national, regional and local control measures to be implemented to reduce emissions and uses air quality modeling and other analyses of air quality and meteorological data to assess the likelihood of reaching attainment in Connecticut by the 2010 attainment deadline.
