Determination of Attainment of the1-Hour Ozone National Ambient Air Quality Standard in the Southeast Desert Nonattainment Area in California
The Environmental Protection Agency (EPA) is proposing to determine that the Southeast Desert nonattainment area has attained the 1-hour ozone National Ambient Air Quality Standard. This proposed determination is based on complete, quality-assured, and certified data for the most recent three-year period (2011-2013).
Air Quality Designations for the 2010 Sulfur Dioxide (SO2
The Environmental Protection Agency (EPA) is providing notice that it has responded to two petitions for reconsideration of a rule published in the Federal Register on August 5, 2013, that promulgated the initial air quality designations for the 2010 Primary SO2 National Ambient Air Quality Standard (NAAQS) for certain areas in the United States. The rule is titled ``Air Quality Designations for the 2010 Sulfur Dioxide (SO2) Primary National Ambient Air Quality Standard.'' One petition was submitted by the Treasure State Resource Industry Association and Yellowstone County, and the other petition was submitted by the Montana Sulphur and Chemical Company (the Petitioners). The EPA carefully considered these petitions and supporting information, along with information contained in the rulemaking docket, in reaching decisions on these petitions. The EPA denied the petitions for reconsideration in separate letters to the Petitioners dated August 14, 2014. The letters explain the EPA's reasons for the denials. One of the Petitioners also requested that the EPA stay the effectiveness of the designations rule, pending reconsideration. Because the EPA denied the reconsideration requests, the EPA also denied the stay request.
Adequacy Status of Motor Vehicle Emissions Budgets in Submitted Fine Particulate Maintenance Plan for Yuba City-Marysville; California
The Environmental Protection Agency (EPA) is notifying the public that the Agency has found that the motor vehicle emissions budgets (MVEBs) for fine particulate (PM2.5) for the years 2017 and 2024 in the Yuba City-Marysville PM2.5 Nonattainment Area Redesignation Request and Maintenance Plan (April 1, 2013) (``Yuba City-Marysville PM2.5 Plan'') are adequate for transportation conformity purposes. The Yuba City-Marysville PM2.5 Plan was submitted to EPA on May 23, 2013 by the California Air Resources Board (CARB) as a revision to the California State Implementation Plan (SIP) and includes a maintenance plan for the 2006 24-hour PM2.5 national ambient air quality standard. Upon the effective date of this notice of adequacy, the Sacramento Area Council of Governments and the U.S. Department of Transportation must use the MVEBs for future conformity determinations.
Approval and Promulgation of Implementation Plans; Florida; Infrastructure Requirement (Visibility) for the 1997 and 2006 PM, and 2008 8-Hour Ozone NAAQS
On April 18, 2008, and September 23, 2009, the Environmental Protection Agency (EPA) received state implementation plan (SIP) submissions from the State of Florida, through the Florida Department of Environmental Protection (FDEP), regarding the infrastructure elements for the 1997 annual Fine Particulate Matter (PM2.5) National Ambient Air Quality Standards (NAAQS) and 2006 24-hour PM2.5 NAAQS, respectively. On October 31, 2012, EPA received a SIP submission from FDEP regarding the infrastructure elements for the 2008 8-hour ozone NAAQS. Additionally, on October 22, 2013, FDEP supplemented the three aforementioned infrastructure SIP submissions. The Clean Air Act (CAA or Act) requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA. These plans are commonly referred to as ``infrastructure'' SIPs. Specifically, EPA is taking final action to approve the submissions for Florida as they relate to the 1997 annual and 2006 24-hour PM2.5 and 2008 8-hour ozone NAAQS infrastructure SIP requirements to protect visibility in other states. All other applicable infrastructure requirements for these NAAQS have been addressed in separate rulemakings. EPA is approving the elements of these infrastructure SIP submissions, as supplemented on October 22, 2013, as they relate to the protection of visibility in other states.
