| E7-21866 | Approval and Promulgation of Air Quality Implementation Plans; West Virginia; 110(a)(1) 8-Hour Ozone Maintenance Plan and Amendments to the 1-Hour Ozone Maintenance Plan | Proposed Rule | EPA is proposing to approve State Implementation Plan (SIP) revisions submitted by West Virginia. These revisions pertain to: the maintenance plan prepared by West Virginia to maintain the 8-hour national ambient air quality standard (NAAQS) for ozone in Greenbrier County, which is designated attainment for the ozone NAAQS; and two amendments to the existing 1-hour ozone maintenance plan, which include (a) removal of the obligation to submit a maintenance plan for the 1- hour NAAQS eight years after approval of the initial 1-hour maintenance plan, and (b) removal of the State's obligation to implement contingency measures upon a violation of the 1-hour NAAQS. The purpose of this proposed approval is to ensure Federal enforceability of the state air program plan and to maintain consistency between the State- adopted plan and the approved SIP. This action is being taken under the Clean Air Act (CAA). | 2007-11-07 | 2007 | 11 | https://www.federalregister.gov/documents/2007/11/07/E7-21866/approval-and-promulgation-of-air-quality-implementation-plans-west-virginia-110a1-8-hour-ozone | https://www.govinfo.gov/content/pkg/FR-2007-11-07/pdf/E7-21866.pdf | Environmental Protection Agency | 145 | EPA is proposing to approve State Implementation Plan (SIP) revisions submitted by West Virginia.
