Air Plan Approvals, Idaho: Logan Utah/Idaho PM2.5

The Environmental Protection Agency (EPA) is approving revisions to Idaho's State Implementation Plan (SIP) submitted in 2012 and 2014 to address Clean Air Act (CAA) requirements for the Idaho portion of the Logan, Utah-Idaho fine particulate matter (PM2.5) nonattainment area (Logan UT-ID area). Based on newly available air quality monitoring data, the EPA is approving Idaho's attainment demonstration and approving Idaho's 2014 Motor Vehicle Emissions Budgets (MVEBs) as early progress budgets. Additionally, the EPA is conditionally approving Reasonable Further Progress (RFP), Quantitative Milestones (QMs), and revised MVEBs for the Idaho portion of the nonattainment area, based on Idaho's commitment to adopt and submit updates to these attainment plan elements within one year of the effective date of this final action.
