## Abstract

EPA is taking direct final action to approve revisions to the Commonwealth of Virginia State Implementation Plan (SIP). The revisions add the primary and secondary lead standards of 0.15 micrograms per cubic meter ([mu]g/m\3\), related reference conditions, and update the list of appendices under "Documents Incorporated by Reference." Virginia's SIP revisions for the national ambient air quality standards (NAAQS) for lead are consistent with the Federal lead standards. This action is being taken under the Clean Air Act (CAA).
