Environmental Protection Agency August 8, 2017 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is approving a portion of the State Implementation Plan (SIP) revision submitted by Mississippi, through the Mississippi Department of Environmental Quality (MDEQ), Office of Pollution Control, on June 7, 2016. Specifically, this action approves the portion of the SIP revision making changes to Mississippi's Prevention of Significant Deterioration (PSD) program by modifying the incorporation by reference (IBR) date for the Federal PSD regulations promulgated by EPA. By changing this date, approval of the SIP revision modifies the existing Greenhouse Gas (GHG) PSD permitting program and incorporates PSD provisions related to the 1997, 2006, and 2012 fine particulate matter (PM2.5) and 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS). This action is being taken pursuant to the Clean Air Act (CAA or Act) and its implementing regulations.

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.

The Environmental Protection Agency (EPA) is taking final action to approve portions of the State Implementation Plan (SIP) submission, submitted on February 8, 2016, by the Commonwealth of Kentucky, through the Energy and Environment Cabinet, Department for Environmental Protection, through the Kentucky Division for Air Quality (KDAQ), to demonstrate that the State meets the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2012 Annual Fine Particulate Matter (PM2.5) national ambient air quality standard (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an ``infrastructure'' SIP. KDAQ certified that the Kentucky SIP contains provisions that ensure the 2012 Annual PM2.5 NAAQS is implemented, enforced, and maintained in Kentucky. EPA has determined that portions of Kentucky's SIP satisfy certain infrastructure elements for the 2012 Annual PM2.5 NAAQS.
