Approval and Promulgation of Air Quality Implementation Plans; Connecticut; Revisions to State Plan for Municipal Waste Combustors and Incorporation of Regulation Into State Implementation Plan for Ozone

Résumé

The EPA is approving revisions to Connecticut's State Plan for Municipal Waste Combustors (MWC) submitted by the Connecticut Department of Environmental Protection (DEP) on November 28, 2000 and October 15, 2001. The MWC State Plan implements and enforces provisions at least as protective as the EPA's Emission Guidelines (EGs) applicable to existing MWC units with capacity to combust more than 250 tons per day of municipal solid waste. Further, the EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Connecticut on October 15, 2001. This is a SIP-strengthening revision that incorporates the nitrogen oxide limits and related regulatory provisions of Connecticut's adopted Regulation Section 22a-174-38, Municipal Waste Combustors, into the SIP to further reduce emissions of nitrogen oxides (NO X ) from MWC units. The EPA proposed approval of these revisions on August 24, 2001, and received no comments during the public comment period which ended September 24, 2001. These actions are being taken under the Clean Air Act.
