Air Plan Approvals, Idaho: Logan Utah/Idaho PM2.5
The Environmental Protection Agency (EPA) is proposing to approve 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 proposing to approve Idaho's attainment demonstration and approve Idaho's 2014 Motor Vehicle Emissions Budgets (MVEBs) as early progress budgets. Additionally, the EPA is proposing to conditionally approve 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 our final action.
Air Plan Approval; Delaware; Infrastructure Requirements for the 2012 Fine Particulate Matter Standard
The Environmental Protection Agency (EPA) is proposing to approve portions of a state implementation plan (SIP) revision submittal from the State of Delaware pursuant to the Clean Air Act (CAA). Whenever new or revised national ambient air quality standards (NAAQS) are promulgated, the CAA requires states to submit a plan for the implementation, maintenance, and enforcement of such NAAQS. The plan is required to address basic program elements, including, but not limited to, regulatory structure, monitoring, modeling, legal authority, and adequate resources necessary to assure attainment and maintenance of the standards. These elements are referred to as infrastructure requirements. Delaware made a SIP submittal to address the infrastructure requirements for the 2012 fine particulate matter (PM2.5) NAAQS. This action proposes to approve portions of this submittal pursuant to section 110 of the CAA. EPA is not proposing any action on the portion of the submittal which addresses interstate transport of emissions and intends to take later separate action on this portion.
Air Plan Approval; Arizona; Stationary Sources; New Source Review
The Environmental Protection Agency (EPA) is proposing approval of regulatory revisions to the Arizona Department of Environmental Quality (ADEQ) portion of the applicable state implementation plan (SIP) for the State of Arizona. These revisions are primarily intended to make corrections to ADEQ's SIP-approved rules for the issuance of New Source Review (NSR) permits for stationary sources, with a focus on preconstruction permit requirements under the Clean Air Act (CAA or Act) for major sources and major modifications. On November 2, 2015, we took final action on a SIP submittal from ADEQ that significantly updated ADEQ's SIP-approved NSR permitting program. However, that action identified several deficiencies in ADEQ's program that needed to be corrected. This proposed action will correct a substantial portion of the deficiencies we identified in that 2015 action. We are seeking comment on our proposed action and plan to follow with a final action.
Determination To Defer Sanctions; Arizona Department of Environmental Quality
The EPA is making an interim final determination to defer imposition of sanctions based on a proposed determination, published elsewhere in this Federal Register, that the State of Arizona (State) has submitted rules that satisfy the requirements of part D of the Clean Air Act (CAA or Act) permitting program for areas under the jurisdiction of the Arizona Department of Environmental Quality (ADEQ).
