The government use of compulsory purchase and land use control powers appears to be increasing worldwide as competition for useable and livable space increases. The need for large and relatively undeveloped space for agriculture and conservation purposes often competes with the need for shelter and the commercial and industrial development accompanying such development for employment, product production and distribution, and other largely urban uses.

Editors' Summary: Property rights advocates implicitly complained in Babbitt v. Sweet Home Chapter of Communities for a Great Oregon that a Fish and Wildlife Service regulation that aimed to protect endangered and threatened species by defining "harm" to include habitat modification impinged on their rights as private landowners by asking them to share with the government responsibility for protecting such species. The U.S. Supreme Court upheld the regulation as reasonable given the relevant language of the Endangered Species Act.

The bedrock notion that courts should, in the overwhelming majority of cases, defer to lawmakers is currently under attack in the nation's courts, commentary, and classrooms. Leading the way are several U.S. Supreme Court Justices who, in cases involving the U.S. Commerce Clause, Takings Clause, and §5 of the Fourteenth Amendment of the U.S. Constitution, are much more willing than their immediate predecessors to second-guess the motives and tactics of elected and appointed officials at all levels of government.

Editors' Summary: Although most talk in terms of wildlife protection seems to focus on the operation of the ESA, there are a host of other federal and state laws designed to protect wildlife from the impacts of resource-development projects—before the species become threatened or endangered.

One of the most prominent issues in the Congressional debate over reauthorization of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund) has been how to reduce "transaction costs" while at the same time fairly and expeditiously resolving liability disputes. This Dialogue asks: Would the allocation procedures proposed in last year's Superfund reauthorization bills meet those sometimes conflicting goals?

Earlier this year in KFC Western, Inc. v. Meghrig, the U.S. Court of Appeals for the Ninth Circuit ruled that private parties may obtain restitution of the costs of cleaning up contaminated property under §7002(a)(1)(B) of the Resource Conservation and Recovery Act (RCRA). The Ninth Circuit's ruling in KFC Western opened the way for private parties to use the RCRA citizen suit provision to recover their costs of investigating, studying, and cleaning up contaminated property from responsible parties.

It is said that nothing is constant except change. For industry trying to keep up with its environmental obligations, perhaps the more appropriate saying would be that nothing is constant except regulatory uncertainty. Under President Barack Obama, the U.S. Environmental Protection Agency (EPA) has pursued wide-sweeping regulatory initiatives under virtually every major environmental statute. These include the Agency's groundbreaking efforts to monitor and regulate mobile and stationary sources of greenhouse gases under the Clean Air Act.

Offshore areas are under pressure to industrialize for renewable energy. To plan for offshore wind development, Rhode Island engaged in a marine spatial planning process that resulted in the Ocean Special Area Management Plan (O-SAMP), a regulatory invention of the Coastal Zone Management Act. Notably, the Rhode Island O-SAMP maps and plans for uses in federal waters beyond the three-mile line dividing state and fedeal jurisdiction, as well as within the state's territorial sea, posing a challenge to the boundaries of offshore federalism.
