Approval and Promulgation of Air Quality Implementation Plans; VA; Redesignation of the City of Fredericksburg, Spotsylvania County, and Stafford County Ozone Nonattainment Area to Attainment and Approval of the Area's Maintenance Plan

Zusammenfassung

EPA is proposing to approve a redesignation request and a State Implementation Plan (SIP) revision submitted by the Commonwealth of Virginia. Virginia is requesting that the city of Fredericksburg, Spotsylvania County, and Stafford County (the Fredericksburg Nonattainment Area) be redesignated as attainment for the eight-hour ozone national ambient air quality standard (NAAQS). The Commonwealth's SIP revision establishes a maintenance plan for the Fredericksburg Nonattainment Area that provides requirements for continued attainment of the eight-hour ozone NAAQS for the next 10 years. EPA is proposing approval of the redesignation request and revision to the Virginia SIP in accordance with the requirements of the Clean Air Act (CAA).
