The Clean Air Act remains one of the most significant and complex pieces of environmental legislation in the country's history. Since its inception, the Clean Air Act has arguably had a greater impact on the lives of Americans than any other environmental statute, and it promises to continue this trend as new legal developments expand its reach. Now fully revised and updated, The Clean Air Act Handbook is an established, comprehensive, and practical examination of the statute and the EPA's implementing regulations and policy guidance. It provides a broad and balanced perspective on all pertinent issues relating to the CAA. It brings together the experience and knowledge of private and public sector Clean Air Act practitioners, including those in law firms, industry, environmental groups, and the U.S. EPA. An ideal reference source for the experienced practitioner as well as a tool for the more general environmental lawyer, The Clean Air Act Handbook covers the entire statute, not just the more recent amendments. This current edition considers the controversial U.S. Supreme Court's Massachusetts v. EPA ruling and the resulting expansion of scope of the statute, including the EPA's expansive new regulatory initiatives aimed at regulating greenhouse gas (GHG) emissions. Topics include: Setting and meeting national ambient air quality standards Transportation and conformity requirements in state implementation plans The new source review program Regulation of hazardous air pollutants Ongoing regulation of mobile sources and of fuels and fuel additives Title IV and the acid rain program Interstate transport of air pollution The CAA and global climate change The Title V operating permit program and how to manage the permit Implementation of CAA programs by American Indian tribes Civil and criminal enforcement Rulemaking and judicial review
