Environmental Change examines the impact of hundreds of federal court decisions on the policies and administration of the EPA since its inception in 1970. Having surveyed over 2,000 federal court decisions, Rosemary O'Leary presents case studies of five important policy areas: water quality, pesticides, toxic substances, air quality, and hazardous wastes. Compliance with court orders, O'Leary discovered, has become one of the EPA's top priorities, at times overshadowing congressional mandates and the authority of EPA administrators. For an agency often caught between the White House and Congressional agendas, the competing interests of industry and environmental groups, and turf battles with other federal agencies, O'Leary argues, judicial decision making is crucial in the public policy process. Environmental Change offers valuable information in the fields of public policy and environmental law.
