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.

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 2015 Ozone 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 for the 2015 Ozone National Ambient Air Quality Standards (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 most areas of Indian country, for the 2015 primary and secondary national ambient air quality standards (NAAQS) for ozone. In this action, the Environmental Protection Agency (EPA) is designating 2,646 counties, including Indian Country located in those counties, two separate areas of Indian Country, and five territories as Attainment/Unclassifiable and three counties as Unclassifiable.

Implementation of 1997 8-Hour Ozone National Ambient Air Quality Standard - Portion of Phase 2 Re. Reasonable Further Progress Emissions Reductions (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Implementation of 1997 8-Hour Ozone National Ambient Air Quality Standard - Portion of Phase 2 Re. Reasonable Further Progress Emissions Reductions (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is taking final action to revise a portion of its Phase 2 implementation rule for the 8-hour ozone National Ambient Air Quality Standard (NAAQS or standard) for which the Agency had sought a voluntary remand from the U.S. Circuit Court of Appeals for the District of Columbia Circuit. The Court granted EPA's request by remanding and vacating that portion of the rule. Specifically, this rule addresses an interpretation that allowed certain credits toward reasonable further progress (RFP) for the 8-hour standard from emissions reductions outside the nonattainment area.

Cross-State Air Pollution Rule Update for the 2008 Ozone National Ambient Air Quality Standards (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Cross-State Air Pollution Rule Update for the 2008 Ozone National Ambient Air Quality Standards (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The Environmental Protection Agency (EPA) published the original Cross-State Air Pollution Rule (original CSAPR) on August 8, 2011, to address interstate transport of ozone pollution under the 1997 ozone National Ambient Air Quality Standards (NAAQS) and interstate transport of fine particulate matter (PM 2.5) pollution under the 1997 and 2006 PM 2.5 NAAQS. The EPA is finalizing this Cross-State Air Pollution Rule Update (CSAPR Update) to address interstate transport of ozone pollution with respect to the 2008 ozone NAAQS. This final rule will benefit human health and welfare by reducing ground-level ozone pollution. In particular, it will reduce ozone season emissions of oxides of nitrogen (NO X) in 22 eastern states that can be transported downwind as NO X or, after transformation in the atmosphere, as ozone, and can negatively affect air quality and public health in downwind areas.

Final Rule to Implement the 1997 8-Hour Ozone National Ambient Air Quality Standard - Classification of Areas That Were Initially Classified (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Final Rule to Implement the 1997 8-Hour Ozone National Ambient Air Quality Standard - Classification of Areas That Were Initially Classified (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The EPA is revising the rules for implementing the 1997 8-hour ozone national ambient air quality standards (NAAQS) to address certain limited portions of the rules vacated by the U.S. Court of Appeals for the District of Columbia Circuit. This final rule assigns Clean Air Act (CAA or Act) classifications and associated state planning and control requirements to selected ozone nonattainment areas. This final rule also addresses three vacated provisions of the 1997 8-hour NAAQS-Phase 1 Implementation Rule (April 30, 2004) that provided exemptions from the anti-backsliding requirements relating to nonattainment area New Source Review (NSR), CAA section 185 penalty fees, and contingency measures, as these three requirements applied for the 1-hour standard. This rule also reinstates the 1-hour contingency measures as applicable requirements that must be retained until the area attains the 1997 8-hour ozone standard. Finally, this rule deletes an obsolete provision that stayed the EPA's authority to revoke the 1-hour ozone standard pending the Agency's issuance of a final rule that revises or reinstates its revocation authority and considers and addresses certain other issues. That rule has now been issued.
