The Environmental Protection Agency (EPA) is proposing to redesignate the West Silver Valley, Idaho nonattainment area to attainment for the 2012 annual fine particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS). EPA is also proposing to approve a maintenance plan for the area demonstrating continued compliance with the NAAQS through 2031, which the Idaho Department of Environmental Quality (IDEQ) submitted along with the redesignation request on June 2, 2020, for inclusion into the Idaho State Implementation Plan (SIP). Additionally, EPA is proposing to approve the 2031 motor vehicle emissions budgets included in Idaho's maintenance plan for PM<INF>2.5</INF>, nitrogen oxides (NO<INF>X</INF>) and volatile organic compounds (VOCs). EPA is proposing this action pursuant to the Clean Air Act (CAA or the Act).
