On January 15, 2013, the Environmental Protection Agency (EPA) published a final rule revising the National Ambient Air Quality Standard (NAAQS) for particulate matter (PM). The revised air quality standards were completed pursuant to the Clean Air Act (CAA) and, in part, in response to a court order and consent agreement. Based on its review of scientific studies available since the agency's previous review in 2006, EPA determined that evidence continued to show associations between particulates in ambient air and numerous significant health problems, including aggravated asthma, chronic bronchitis, nonfatal heart attacks, and premature death. Populations shown to be most at risk include children, older adults, and those with heart and lung disease, and those of lower socioeconomic status. EPA's review of and revisions to the PM NAAQS have generated considerable debate and oversight in Congress. The January 2013 revisions change the existing (2006) annual health-based ("primary") standard for "fine" particulate matter 2.5 micrometers or less in diameter (or PM2.5), lowering the allowable average concentration of PM2.5 in the air from the current level of 15 micrograms per cubic meter ( g/m3) to a limit of 12 g/m3. The annual PM2.5 NAAQS is set so as to address human health effects from chronic exposures to the pollutants. The existing "24-hour primary standard" for PM2.5 that was reduced from 65 g/m3 to 35 g/m3 in 2006 was retained, as was the existing standard for larger, but still inhalable, "coarse" particles less than 10 micrometers in diameter, or PM10. As it did in 2006, EPA set "secondary" standards that provide protection against "welfare" (nonhealth) effects, such as ecological effects and material deterioration, identical to the primary standards. EPA revised the Regulatory Impact Analysis (RIA) accompanying its June 2012 proposed rule in part in response to comments received regarding the agency's cost and benefit estimates. In its December 2012 RIA, EPA estimated that the potential "quantifiable" health benefits (2010 $) associated with attaining the PM standard would range from $4.0 billion to $9.1 billion, and costs (2010 $) would range from $53.0 million to $353.0 million. Some stakeholders and some Members continue to express concerns that cost impacts would be more significant than those estimated by EPA for those areas out of compliance with the new standards. EPA's revisions to the PM NAAQS do not directly regulate emissions from specific sources, or compel installation of any pollution control equipment or measures, but indirectly could affect operations at industrial facilities and other sources throughout the United States. Revising PM NAAQS starts a process that includes a determination of areas in each state that exceed the standard and must, therefore, reduce pollutant concentrations to achieve it. Following determinations of these "nonattainment" areas based on multiple years of monitoring data and other factors, state and local governments must develop (or revise) State Implementation Plans (SIPs) outlining measures to attain the standard. These include promulgation of new regulations by states, and the issuance of revised air permits. The process typically takes several years. As per statutory scheduling requirements, on December 18, 2014, EPA classified 14 areas as "Moderate" nonattainment for the revised 2013 primary annual PM2.5 standard. The areas include 38 counties or portions of counties in six states-California, Idaho, Indiana, Kentucky, Ohio, and Pennsylvania. EPA also deferred the designation period for 11 other areas by up to one year, and designated all other areas as "unclassifiable" or as "unclassifiable/attainment." CAA section 188(c) requires Moderate areas to achieve attainment as expeditiously as practicable, but no later than six years after the effective date of final area designation.

The President makes appointments to positions within the federal government, either using the authorities granted to the President alone or with the advice and consent of the Senate. This report identifies all nominations that were submitted to the Senate for full-time positions in 40 organizations in the executive branch (27 independent agencies, 6 agencies in the Executive Office of the President EOP], and 7 multilateral organizations) and 4 agencies in the legislative branch. It excludes appointments to executive departments and to regulatory and other boards and commissions, which are covered in other reports. Information for each agency is presented in tables. The tables include full-time positions confirmed by the Senate, pay levels for these positions, and appointment action within each independent agency. Additional summary information across all agencies covered in the report appears in the appendix. During the 112th Congress, the President submitted 34 nominations to the Senate for full-time positions in independent agencies, agencies in the EOP, multilateral agencies, and legislative branch agencies. Of these 34 nominations, 27 were confirmed, 1 was withdrawn, and 6 were returned to him in accordance with Senate rules. For those nominations that were confirmed, a mean (average) of 142.7 days elapsed between nomination and confirmation. The median number of days elapsed was 112.0. The President made one recess appointment to a full-time position in an independent agency during the 112th Congress. Information for this report was compiled using the Senate nominations database of the Legislative Information System (LIS) at http: //www.lis.gov/nomis/, the Congressional Record (daily edition), the Weekly Compilation of Presidential Documents, telephone discussions with agency officials, agency websites, the United States Code, and the 2012 Plum Book (United States Government Policy and Supporting Positions)
