Connecticut's PM 2.5 Demonstration - Final Submission

Annual Fine Particulate Matter (PM 2.5) Attainment Demonstration
Final SIP Submitted to EPA November 18, 2008

Background and information on the PM2.5 Demonstration SIP:

The documents below present the Connecticut Department of Energy and Environmental Protection’s (CT DEEP) state implementation plan (SIP) for attaining the 1997 annual National Ambient Air Quality Standard (NAAQS) for fine particulate matter (PM2.5). This PM2.5 NAAQS Attainment Demonstration has two major components:  (1) a description of the national, regional and local control measures that have been or will be implemented to reduce emissions contributing to PM2.5 in future years; and (2) air quality modeling and other analyses of air quality and meteorological data to assess the likelihood of reaching PM2.5 attainment by the mandated 2010 attainment deadline.  Results of the analyses described in this attainment demonstration lead CT DEEP to conclude that attainment in the New York-New Jersey-Connecticut nonattainment area will be achieved by the April 2010 attainment date.  Air quality modeling of future emissions, grown and controlled to 2009, plus other evidence of forthcoming emission reductions indicate that the previously non-attaining air quality levels in New York City and northern New Jersey will achieve compliance by the April 2010 attainment date.   All Connecticut monitors continue to measure compliance with the annual PM2.5  NAAQS, with monitored PM2.5 levels in Connecticut exhibiting a general downward trend from 2001 through 2007 as a result of control program implementation.

Control Measure Appendix:

The U.S. Environmental Protection Agency (EPA) noted that some of the post-2002 control measures identified in the Connecticut 1997 Annual PM2.5 NAAQS Attainment Demonstration are not approved in the state implementation plan (SIP). In response, the Connecticut Department of Energy and Environmental Protection (CT DEEP) is submitting the following four control measures into the SIP as measures producing directionally correct emissions reductions in support of attainment of the 1997 annual PM2.5 NAAQS:

  • Control of sulfur dioxide emissions from power plants and other large stationary sources, Section 22a-174-19a of the Regulations of Connecticut State Agencies (RCSA) (submitted in part);
  • VOC reductions from the manufacture and use of adhesives and sealants, RCSA Section 22a-174-44;
  • Outdoor wood burning furnace restrictions, Section 22a-174k of the Connecticut General Statutes and
  • General Permit to Construct and/or Operate a New or Existing Distributed Generation Resource.

Although the emissions reductions anticipated from the last three of these measures are not quantified for the purposes of the 1997 Annual PM2.5 NAAQS Attainment Demonstration, CT DEEP notes that the VOC emissions reductions of RCSA section 22a-174-44 were included in the attainment modeling and quantified for the purposes of the Connecticut 8-Hour Ozone Attainment Demonstration, which was submitted to EPA on February 1, 2008.
With regard to RCSA section 22a-174-19a, CT DEEP is requesting approval only for portions of the regulation. A version of the regulation is submitted with strikeout font to indicate those portions of the regulation that CT DEEP is not submitting for approval.
