Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Update of the Motor Vehicle Emissions Budgets for the Lancaster 1997 8-Hour Ozone Maintenance Area

Résumé

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Commonwealth of Pennsylvania's (Pennsylvania) State Implementation Plan (SIP). One revision consists of an update to the SIP-approved Motor Vehicle Emissions Budgets (MVEBs) for nitrogen oxides (NO X ) and volatile organic compounds (VOCs) for the 1997 8-Hour Ozone National Ambient Air Quality Standard (NAAQS) SIP for Lancaster County (also referred to as the "Lancaster Maintenance Area"). The other SIP revision updates the point source inventory for NO X and VOCs. In the Final Rules section of this Federal Register, EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this action, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period.
