On June 19, 2017, the Connecticut Department of Energy and Environmental Protection (CTDEEP) issued a notice of intent to revise its State Implementation Plan (SIP) to comply with the 2008 National Ambient Air Quality Standards (NAAQS) for Ozone. The revision fulfills CTDEEP's requirements to address an attainment demonstration for the Connecticut portion of the New York - Northern New Jersey - Long Island, (NY-NJ-CT) Nonattainment Area. The Connecticut portion consists of the southwest state counties Fairfield, New Haven and Middlesex. Specifically, the proposed SIP revision describes the national, regional and local control measures to be implemented to reduce emissions, and assesses the likelihood of achieving the moderate non-attainment classification for this region. CTDEEP demonstrates that, with the proposed measures, the Southwest Connecticut Nonattainment area is likely to attain the 1997 ozone NAAQS but won't be able to attain the 2008 ozone NAAQS by the July 20, 2018 deadline. This is primarily due to the inability of the U.S. Environmental Protection Agency (EPA) to implement measures to reduce the interstate transport of ozone forming emissions, and the inability of upwind states to reduce their state generated emissions.

Comments on the proposed SIP revision may be submitted to the CTDEEP by 4:30 PM on July 25, 2017 via email or mail. Emailed comments should be sent to kathleen.knight@ct.gov. Comments sent via standard mail should be addressed to: Kathleen Knight, Connecticut Department of Energy and Environmental Protection, Bureau of Air Management, 5th Floor, 79 Elm Street, Hartford, Connecticut 06106. The CTDEEP will also hold a public hearing at CTDEEP's office at 10:00 AM on July 25, 2017.

Additional details regarding the proposed SIP revision and public hearing can be found on CTDEEP's website.
