摘要

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the Commonwealth of Pennsylvania's (Pennsylvania) State Implementation Plan (SIP). The revisions consist of an update to the SIP-approved Motor Vehicle Emissions Budgets (MVEBs) for nitrogen oxides (NO X ) and volatile organic compounds (VOCs), and an updated point source inventory for NO X and VOCs for the 1997 8-Hour Ozone National Ambient Air Quality Standard (NAAQS) SIP for Lancaster County (hereafter referred to as the "Lancaster Maintenance Area"). EPA's approval of the updated MVEBs makes them available for transportation conformity purposes. EPA is approving these revisions to the MVEBs and point source inventory in accordance with the requirements of the Clean Air Act (CAA).
