The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the Connecticut Department of Energy and Environmental Protection (CT DEEP) to (1) remove State Order 7002B issued to Dow Chemical USA (Dow) in Gales Ferry on May 25, 1982, from the Connecticut SIP, (2) remove State Order 8027 issued to Pratt & Whitney Division of United Technologies Corporation (Pratt & Whitney) in North Haven on March 22, 1989, from the Connecticut SIP, and (3) add Consent Order 8381 issued to Thames Shipyard and Repair Company (Thames Shipyard) in New London, CT on December 3, 2021, to the Connecticut SIP. State Orders 8027 and 7002B addressed reasonably available control technology (RACT) for volatile organic compound (VOC) emissions and sulfur fuel content limits for Pratt & Whitney and Dow, respectively. EPA is approving the Thames Shipyard Order into Connecticut's SIP to ensure RACT requirements with respect to VOC emissions from shipbuilding and repair operations continue to be implemented at Thames Shipyard. This action is being taken in accordance with the Clean Air Act.
