Book excerpt: In conjunction with the 50th anniversary of the creation of the Environmental Protection Agency, this book brings together leading scholars and EPA veterans to provide a comprehensive assessment of the agency’s key decisions and actions in the various areas of its responsibility. Themes across all chapters include the role of rulemaking, negotiation/compromise, partisan polarization, judicial impacts, relations with the White House and Congress, public opinion, interest group pressures, environmental enforcement, environmental justice, risk assessment, and interagency conflict. As no other book on the market currently discusses EPA with this focus or scope, the authors have set out to provide a comprehensive analysis of the agency’s rich 50-year history for academics, students, professional, and the environmental community.
