More than four decades after it was enacted, the Clean Air Act remains one of the most signficant and sweeping pieces of environmental legislation in the country's history. Now fully revised and updated, The Clean Air Act Handbook is an established, comprehensive examination of the statute and the EPA's implementing regulations and policy guidance. Since the last edition, the Clean Air Act has evolved into the tool for achieving the regulation of greenhouse gas emissions that cause climate change. The important yet controversial U.S. Supreme Court 2007 decision in Massachusetts v. EPA has resulted in the single largest expansion of the scope of the statute in history, making the need for an updated edition of this comprehensive manual greater than ever. The Clean Air Act Handbook provides a broad and balanced perspective on all pertinent issues relating to the CAA. It brings together the experience and knowledge of 31 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 explains how the act's history informs much of the changes that occurred in the amendments and allows those changes to be seen in context. Each chapter is followed by detailed citations to the statute, cases, regulations, legislative history and EPA guidance. The Handbook includes a current list of EPA web sites containing information on Clean Air Act issues and a list of all regional office web site addresses. The book also includes a general glossary of acronyms and related terms as well as a comprehensive index.
