Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Tennessee; Redesignation of the Knoxville 2008 8-Hour Ozone Nonattainment Area to Attainment
The Environmental Protection Agency (EPA) is taking four separate final actions related to a state implementation plan (SIP) revision submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), Division of Air Pollution Control, on November 14, 2014, for the Knoxville, Tennessee 8-hour ozone nonattainment area (hereinafter referred to as the ``Knoxville Area'' or ``Area''). The Knoxville Area includes a portion of Anderson County as well as Blount and Knox Counties in their entireties. EPA is approving the base year emissions inventory for the 2008 8-hour ozone national ambient air quality standards (NAAQS) for the Knoxville Area; determining that the Knoxville Area is attaining the 2008 8-hour ozone NAAQS; approving into the SIP the State's plan for maintaining attainment of the 2008 8-hour ozone NAAQS in the Area, including the 2011 and 2026 motor vehicle emission budgets (MVEBs) for nitrogen oxides (NOX) and volatile organic compounds (VOC); and redesignating the Area to attainment for the 2008 8-hour ozone NAAQS. EPA is also finding the 2011 and 2026 MVEBs for NOX and VOC for the Knoxville Area adequate for the purposes of transportation conformity.
Notice of Receipt of Requests for Amendments To Terminate Uses in Certain Pesticide Registrations; Correction
EPA issued a notice in the Federal Register of June 10, 2015, concerning amendments to terminate uses in certain pesticide registrations. This document corrects errors in the sections titled ``DATES'' and ``What action is the agency taking?''.
Revisions to the California State Implementation Plan, South Coast Air Quality Management District
The Environmental Protection Agency (EPA) is taking action to approve a revision to the South Coast Air Quality Management District (SCAQMD) portion of the California State Implementation Plan (SIP). This revision concerns volatile organic compound (VOC) emissions from Large Confined Animal Facilities. We are approving a local rule to regulate these emission sources under the Clean Air Act (CAA or the Act).
Findings of Failure To Submit a Section 110 State Implementation Plan for Interstate Transport for the 2008 National Ambient Air Quality Standards for Ozone
The Environmental Protection Agency (EPA) is taking final action finding that 24 states have failed to submit infrastructure State Implementation Plans (SIPs) to satisfy certain interstate transport requirements of the Clean Air Act (CAA) with respect to the 2008 8-hour ozone national ambient air quality standard (NAAQS). Specifically, these requirements pertain to significant contribution to nonattainment, or interference with maintenance, of the 2008 8-hour ozone NAAQS in other states. These findings of failure to submit establish a 2-year deadline for the EPA to promulgate a Federal Implementation Plan (FIP) to address the interstate transport SIP requirements pertaining to significant contribution to nonattainment and interference with maintenance unless, prior to the EPA promulgating a FIP, the state submits, and the EPA approves, a SIP that meets these requirements.
Approval and Promulgation of Air Quality Implementation Plans; Maryland; Preconstruction Requirements-Nonattainment New Source Review
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted on August 22, 2013 by the Maryland Department of the Environment (MDE) on behalf of the State of Maryland. This revision pertains to Maryland's major nonattainment New Source Review (NSR) program, notably preconstruction permitting requirements for sources of fine particulate matter (PM2.5). This action is being taken under the Clean Air Act (CAA).
Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles-Phase 2
EPA and NHTSA, on behalf of the Department of Transportation, are each proposing rules to establish a comprehensive Phase 2 Heavy- Duty (HD) National Program that will reduce greenhouse gas (GHG) emissions and fuel consumption for new on-road heavy-duty vehicles. This technology-advancing program would phase in over the long-term, beginning in the 2018 model year and culminating in standards for model year 2027, responding to the President's directive on February 18, 2014, to develop new standards that will take us well into the next decade. NHTSA's proposed fuel consumption standards and EPA's proposed carbon dioxide (CO2) emission standards are tailored to each of four regulatory categories of heavy-duty vehicles: Combination tractors; trailers used in combination with those tractors; heavy-duty pickup trucks and vans; and vocational vehicles. The proposal also includes separate standards for the engines that power combination tractors and vocational vehicles. Certain proposed requirements for control of GHG emissions are exclusive to EPA programs. These include EPA's proposed hydrofluorocarbon standards to control leakage from air conditioning systems in vocational vehicles, and EPA's proposed nitrous oxide (N2O) and methane (CH4) standards for heavy-duty engines. Additionally, NHTSA is addressing misalignment in the Phase 1 standards between EPA and NHTSA to ensure there are no differences in compliance standards between the agencies. In an effort to promote efficiency, the agencies are also proposing to amend their rules to modify reporting requirements, such as the method by which manufacturers submit pre-model, mid-model, and supplemental reports. EPA's proposed HD Phase 2 GHG emission standards are authorized under the Clean Air Act and NHTSA's proposed HD Phase 2 fuel consumption standards authorized under the Energy Independence and Security Act of 2007. These standards would begin with model year 2018 for trailers under EPA standards and 2021 for all of the other heavy-duty vehicle and engine categories. The agencies estimate that the combined standards would reduce CO2 emissions by approximately 1 billion metric tons and save 1.8 billion barrels of oil over the life of vehicles and engines sold during the Phase 2 program, providing over $200 billion in net societal benefits. As noted, the proposal also includes certain EPA-specific provisions relating to control of emissions of pollutants other than GHGs. EPA is seeking comment on non- GHG emission standards relating to the use of auxiliary power units installed in tractors. In addition, EPA is proposing to clarify the classification of natural gas engines and other gaseous-fueled heavy- duty engines, and is proposing closed crankcase standards for emissions of all pollutants from natural gas heavy-duty engines. EPA is also proposing technical amendments to EPA rules that apply to emissions of non-GHG pollutants from light-duty motor vehicles, marine diesel engines, and other nonroad engines and equipment. Finally, EPA is proposing to require that rebuilt engines installed in new incomplete vehicles meet the emission standards applicable in the year of assembly, including all applicable standards for criteria pollutants.
