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

Attainment Demonstrations for the 2008 Ozone NAAQS

Attainment demonstrations are required by the Clean Air Act (CAA) for areas classified as moderate nonattainment or above. While both areas were originally designated as marginal nonattainment based on monitored ozone levels, these designations underestimated the significant persistence of the ozone problem and the areas were unable to attain the standard by the marginal deadline and were thereby reclassified by the EPA to moderate on June 3, 2016, and again reclassified to serious nonattainment on August 23, 2019.

Statewide SIP Revisions for the Redesignation to Serious Nonattainment
This revision builds on the earlier SIPs below to fulfill the requirements for the reclassifications to serious nonattainment. Consideration is given for Greater Connecticut's Clean Data Determination, on July 13, 2020, indicating attainment of the standards in that area.

New York -N. New Jersey- Long Island, NY-NJ-CT Attainment Demonstration
This revision addresses the Connecticut portion of the New York-N. New Jersey-Long Island, NY-NJ-CT Nonattainment area (Southwest Connecticut: Fairfield, New Haven and Middlesex Counties). Specifically, DEEP is submitting the following to meet the requirement of an Attainment Demonstration under the moderate classification for the 2008 ozone standard and to address the 1997 ozone standard State Implementation Plan (SIP) call. The plan demonstrates that Connecticut has addressed the requirements as outlined under the Clean Air Act (CAA) for an area such as Southwest Connecticut. However, it also demonstrates that Connecticut is overwhelmingly impacted by out of state emissions. In fact, the worst observed air quality in Connecticut is 95% due to emissions other than Connecticut's sources. Therefore, the problem of ozone in Southwest Connecticut is only solvable if upwind states fully address their obligations under the Good Neighbor provisions of the CAA, which to date, they have failed to do so.  
 
Final Submission, August 8, 2017 :
Public Hearing will be held July 25, 2017. All written comments must be received by July 25, 2017. See the Notice below for more details.
Greater Connecticut Attainment Demonstration
On January 17, 2017 DEEP submitted the the clean air plan, to demonstrate how Greater Connecticut will come into compliance with the 2008 national air quality standard for ozone, to the Environmental Protection Agency. This plan was developed to meet the requirements set out in the federal Clean Air Act, including a commitment to further reducing air pollution in Connecticut and adopting Motor Vehicle Emissions Budgets. All documents are in PDF format unless otherwise indicated.
