Phase 2 of the Final Rule To Implement the 8-Hour Ozone National Ambient Air Quality Standard - Notice of Reconsideration (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Phase 2 of the Final Rule To Implement the 8-Hour Ozone National Ambient Air Quality Standard - Notice of Reconsideration (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 On December 19, 2006, EPA published, as a proposed rule, a notice of reconsideration for several aspects of the November 29, 2005, Phase 2 of the final rule to implement the 8-hour ozone national ambient air quality standard (NAAQS). These issues relate to nitrogen oxide (NO X) reasonably available control technology (RACT) for electric generating units (EGUs) in Clean Air Interstate Rule (CAIR) states and to certain new source review (NSR) provisions. The notice of reconsideration was published as a result of a petition for reconsideration which had been submitted by the Natural Resources Defense Council. In this action, EPA summarizes and responds to comments received in response to the notice of reconsideration, and EPA announces its final actions taken in response to these comments.

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.

The social cost of carbon (SC-CO2) is an economic metric intended to provide a comprehensive estimate of the net damages - that is, the monetized value of the net impacts, both negative and positive - from the global climate change that results from a small (1-metric ton) increase in carbon-dioxide (CO2) emissions. Under Executive Orders regarding regulatory impact analysis and as required by a court ruling, the U.S. government has since 2008 used estimates of the SC-CO2 in federal rulemakings to value the costs and benefits associated with changes in CO2 emissions. In 2010, the Interagency Working Group on the Social Cost of Greenhouse Gases (IWG) developed a methodology for estimating the SC-CO2 across a range of assumptions about future socioeconomic and physical earth systems. Valuing Climate Changes examines potential approaches, along with their relative merits and challenges, for a comprehensive update to the current methodology. This publication also recommends near- and longer-term research priorities to ensure that the SC- CO2 estimates reflect the best available science.

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.

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.
