Re: Revision to the Connecticut State Implementation Plan - 

Submittal of the Connecticut Low Emissions Vehicle Program as an Additional Control 

Strategy for the 8-Hour Ozone Attainment Demonstration 

Dear Mr. Conroy, 

Pursuant to 40 CFR 51, Appendix V, Section 2.1(a), I am submitting an original and two 

copies of this letter and supporting materials on behalf of the State of Connecticut Department of 

Environmental Protection (CT DEP) to request that your agency approve the enclosed material 

as a revision to the Connecticut State Implementation Plan (SIP) for air quality. This proposed 

SIP revision consists of the Connecticut Low Emissions Vehicle Program (CT LEV), as adopted 

in 2004, and subsequently amended in 2005 and 2009. The CT LEV program is cited as a 

weight-of-evidence measure in the 8-Hour Ozone Attainment Demonstration that Connecticut 

submitted to the United States Environmental Protection Agency as a proposed SIP revision on 

February 1, 2008. 

The CT LEV requirements were adopted on December 4, 2004, and amended on 

December 22, 2005 and August 4, 2009, each time in accordance with all required state and 

federal procedures for public participation in satisfaction of the requirements of 40 CFR 51, 

Appendix V, Section 2. To demonstrate such compliance, a certified copy of the regulation for 

each rulemaking is enclosed along with the public notice, certification of public hearing, and 

hearing reports, which include summaries of the comments received and a description of any 

changes made during the course of each rulemaking process. 

The materials necessary for your agency to process this SIP revision are attached . Please 

contact Tracy Babbidge at (860) 424-3027, if you have any questions or need any additional 

information. Thank you for your assistance in this matter . 

Yours truly,
