The West Virginia Department of Environmental Protection (WVDEP) is requesting that the West Virginia portion of the Parkersburg-Marietta, WV-OH fine particulate matter (PM<INF>2.5</INF>) nonattainment area (Parkersburg-Marietta Area or Area) be redesignated as attainment for the 1997 annual PM<INF>2.5</INF> national ambient air quality standard (NAAQS). The Parkersburg-Marietta Area is comprised of Wood County and a portion of Pleasants County in West Virginia (West Virginia portion of the Area); and Washington County in Ohio. In this rulemaking action, EPA is proposing to approve the PM<INF>2.5</INF> redesignation request for the West Virginia portion of the Parkersburg- Marietta Area. EPA is also proposing to approve the maintenance plan SIP revision that the State submitted in conjunction with its redesignation request. The maintenance plan provides for continued attainment of the 1997 annual PM<INF>2.5</INF> NAAQS for 10 years after redesignation of the West Virginia portion of the Area. The maintenance plan includes an insignificance determination for the on-road motor vehicle contribution of PM<INF>2.5</INF>, nitrogen oxides (NO<INF>X</INF>), and sulfur dioxide (SO<INF>2</INF>) for the West Virginia portion of the Area for purposes of transportation conformity. EPA is proposing to find that West Virginia's insignificance determination for transportation conformity is adequate.\1\ EPA is also proposing to find that the Area continues to attain the standard. This action to propose approval of the 1997 annual PM<INF>2.5</INF> NAAQS redesignation request, maintenance plan, and insignificance determination for transportation conformity for the West Virginia portion of the Area is based on EPA's determination that the Area has met the criteria for redesignation to attainment specified in the Clean Air Act (CAA). EPA is taking separate action to propose redesignation of the Ohio portion of the Parkersburg-Marietta Area. --------------------------------------------------------------------------- | 2012-12-11 | 2012 | 12 | https://www.federalregister.gov/documents/2012/12/11/2012-29865/approval-and-promulgation-of-air-quality-implementation-plans-west-virginia-redesignation-of-the | https://www.govinfo.gov/content/pkg/FR-2012-12-11/pdf/2012-29865.pdf | Environmental Protection Agency | 145 | EPA is proposing to approve a redesignation request and State Implementation Plan (SIP) revision submitted by the State of West Virginia.
