Air Quality Designations for the 2008 Ozone National Ambient Air Quality Standards - Final Rule (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Air Quality Designations for the 2008 Ozone National Ambient Air Quality Standards - Final Rule (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 This rule establishes initial air quality designations for most areas in the United States, including areas of Indian country, for the 2008 primary and secondary national ambient air quality standards (NAAQS) for ozone. The designations for several counties in Illinois, Indiana, and Wisconsin that the EPA is considering for inclusion in the Chicago nonattainment area will be designated in a subsequent action, no later than May 31, 2012. Areas designated as nonattainment are also being classified by operation of law according to the severity of their air quality problems. The classification categories are Marginal, Moderate, Serious, Severe, and Extreme. The EPA is establishing the air quality thresholds that define the classifications in a separate rule that the EPA is signing and publishing in the Federal Register on the same schedule as these designations. In accordance with that separate rule, six nonattainment areas in California are being reclassified to a higher classification.

Air Quality Designations for the 2008 Lead (Pb) National Ambient Air Quality Standards - Final Rule (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Air Quality Designations for the 2008 Lead (Pb) National Ambient Air Quality Standards - Final Rule (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 This rule establishes air quality designations for certain areas in the United States for the 2008 lead (Pb) National Ambient Air Quality Standards (NAAQS). Based on air quality monitoring data, EPA is issuing this rule to identify areas that do not meet the 2008 Pb NAAQS and areas that contribute to Pb air pollution in a nearby area that does not meet the Pb NAAQS. EPA is deferring designation for all other areas of the United States, including Indian country, pending collection and review of additional data from recently deployed Pb monitors. The Clean Air Act (CAA) requires areas designated nonattainment by this rule to undertake certain planning and pollution control activities to attain the standards as quickly as reasonably possible.

Air Quality Designations - 2012 Primary Annual Fine Particle National Ambient Air Quality Standards (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Air Quality Designations - 2012 Primary Annual Fine Particle National Ambient Air Quality Standards (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 This rule establishes air quality designations for most areas in the United States (U.S.), including areas of Indian country, for the 2012 primary annual fine particle (PM 2.5) National Ambient Air Quality Standards (NAAQS). Through these designations, the Environmental Protection Agency (EPA) is identifying as "nonattainment" those areas that are violating the 2012 PM 2.5 NAAQS based on quality-assured, certified air quality monitoring data from 2011 to 2013 or those areas that are contributing to a violation of the NAAQS in a nearby area. The EPA is initially classifying all nonattainment areas as Moderate. Also, through this final rule, the EPA is designating several areas as "unclassifiable" where the EPA cannot determine based on available information whether the area is meeting or not meeting the NAAQS or where the EPA has not determined whether the area contributes to a nearby violation. Additionally, the EPA is deferring initial area designations for several areas where the EPA cannot determine using available data whether the areas are meeting or are not meeting the NAAQS, but for which forthcoming data will likely result in complete and valid data needed to determine a designation. The EPA will assess these data as they become available and promulgate initial area designations for the deferred areas through a separate rulemaking action. The EPA is designating as "unclassifiable/attainment" all remaining areas of the country.

Implementation of the 2008 National Ambient Air Quality Standards for Ozone - Nonattainment Area Classifications Approach (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Implementation of the 2008 National Ambient Air Quality Standards for Ozone - Nonattainment Area Classifications Approach (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 In this final rule, the EPA is establishing the air quality thresholds that define the classifications assigned to all nonattainment areas for the 2008 ozone national ambient air quality standards (NAAQS) (the "2008 ozone NAAQS") which were promulgated on March 12, 2008. The EPA is also granting reclassification for selected nonattainment areas that voluntarily reclassified under the 1997 ozone NAAQS. This rule also establishes December 31 of each relevant calendar year as the attainment date for all nonattainment area classification categories. Finally, this rule provides for the revocation of the 1997 ozone NAAQS for transportation conformity purposes to occur 1 year after the effective date of designations for the 2008 ozone NAAQS.

National Ambient Air Quality Standards for Ozone (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the National Ambient Air Quality Standards for Ozone (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 Based on its review of the air quality criteria for ozone (O 3) and related photochemical oxidants and national ambient air quality standards (NAAQS) for O 3, the Environmental Protection Agency (EPA) is revising the primary and secondary NAAQS for O 3 to provide requisite protection of public health and welfare, respectively. The EPA is revising the levels of both standards to 0.070 parts per million (ppm), and retaining their indicators (O 3), forms (fourth-highest daily maximum, averaged across three consecutive years) and averaging times (eight hours). The EPA is making corresponding revisions in data handling conventions for O 3 and changes to the Air Quality Index (AQI); revising regulations for the prevention of significant deterioration (PSD) program to add a transition provision for certain applications; and establishing exceptional events schedules and providing information related to implementing the revised standards. The EPA is also revising the O 3 monitoring seasons, the Federal Reference Method (FRM) for monitoring O 3 in the ambient air, Federal Equivalent Method (FEM) analyzer performance requirements, and the Photochemical Assessment Monitoring Stations (PAMS) network. Along with exceptional events schedules related to implementing the revised O 3 standards, the EPA is applying this same schedule approach to other future new or revised NAAQS and removing obsolete regulatory language for expired exceptional events deadlines. The EPA is making minor changes to the procedures and time periods for evaluating potential FRMs and equivalent methods, including making the requirements for nitrogen dioxide (NO 2) consistent with the requirements for O 3, and removing an obsolete requirement for the annual submission of Product Manufacturing Checklists by manufacturers of FRMs and FEMs for monitors of fine and coarse particulate matter.

Additional Air Quality Designations for the 2006 24-Hour Fine Particle National Ambient Air Quality Standards, 110(k)(6) Correction (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Additional Air Quality Designations for the 2006 24-Hour Fine Particle National Ambient Air Quality Standards, 110(k)(6) Correction (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 On November 13, 2009, EPA promulgated air quality designations nationwide for all but three areas for the 2006 24-hour fine particle (PM 2.5) National Ambient Air Quality Standards (NAAQS). This rule takes several additional actions related to the 2006 24-hour PM 2.5 NAAQS designations. It establishes the initial PM 2.5 air quality designations for three areas (Pinal County, Arizona; Plumas County, California; and Shasta County, California) and their respective surrounding counties that EPA deferred in the November 13, 2009 promulgated designations. Plumas and Shasta counties and their surrounding counties are being designated "unclassifiable/attainment," while a portion of Pinal County is being designated as "nonattainment." This action also includes a 110(k)(6) error correction (affecting Ravalli, Montana) and a technical correction (affecting Knoxville, Tennessee) related to the 2006 24-hour PM 2.5 NAAQS designations. Finally, in this action, EPA announces its decision to retain the current designation of unclassifiable/attainment for Harris County, Texas and Pinal County, Arizona for the 1997 annual PM 2.5 NAAQS.
