Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Approval of Revision to the 1990 Baseyear Inventory for Rockwell Heavy Vehicles, Inc.

EPA is taking direct final action to approve a revision to the Commonwealth of Pennsylvania State Implementation Plan (SIP) submitted by the Pennsylvania Department of Environmental Protection (PADEP) on April 8, 1998. This revision consists of including the carbon monoxide (CO), volatile organic compounds (VOC) and nitrogen oxides (NO<INF>X</INF>) emissions from Rockwell Heavy Vehicles, Inc., New Castle Forge Plant, in Lawrence County (Rockwell) in the point source portion of Pennsylvania's 1990 baseyear emission inventory. The intended effect of this action is to grant approval of the revision to the 1990 baseyear inventory and in so doing to render Rockwell's emissions eligible for consideration as emission reduction credits (ERCs) in accordance with the Pennsylvania SIP.
