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. Rocky Neck State Park is also closed until further notice due to a brush fire. Please note that today's forest fire danger report remains at a 'very high' or 'extreme' level.

Asbestos Demolition and Renovation

40 CFR part 61, Subpart M, National Emission Standard for Hazardous Air Pollutants for Asbestos (Asbestos NESHAP) specifies demolition and renovation work practices involving asbestos and requires that building owners or operators notify the appropriate state or federal agency of potential asbestos hazards prior to demolition or renovation. On December 14, 2017, DEEP voluntarily and partially withdrew from the delegated authority to implement and enforce provisions of the Asbestos NESHAP. However, DEEP retains its delegation to implement and enforce the Asbestos NESHAP for Title V sources. Therefore, Title V sources must submit an Asbestos Demolition Notification to DEEP and non-Title V sources must submit a Notification of Demolition and Renovation to EPA. For more information refer to Asbestos National Emission Standards for Hazardous Air Pollutants (NESHAP) (EPA). Sources must also comply with the Connecticut Department of Public Health's Asbestos Program requirements.
