Approval and Promulgation of Air Quality Implementation Plans; Connecticut; Approval of Several NOX Emission Trading Orders as Single Source SIP Revisions

EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Connecticut. This revision establishes a mechanism to create and use emission trading credits for nitrogen oxides ( NO<INF>X</INF>) at electric generating facilities currently owned by Wisvest in Bridgeport and New Haven, Connecticut. This revision also approves retrospectively credits created at these facilities between April 16, 2000 and April 30, 2000. These credits can be used by facilities to comply with the NO<INF>X</INF> emission limits required by Connecticut regulation 22a-174-22 (Control of Nitrogen Oxides). The revision also approves annual emission credits at Wisvest's power plant Bridgeport Harbor Station (unit no. 2). These annual credits can be used by facilities to offset any NO<INF>X</INF> emission increases due to new construction or plant modification subject to EPA's nonattainment new source review program. Lastly, this revision changes the expiration date from December 1999 to December 2000 of previously issued Orders to four municipal waste incinerators. The intended effect of this action is this SIP revision in accordance with the Clean Air Act.
