Editors' Summary: Until recently, the regulation of chemical carcinogens and the regulation of radiological carcinogens developed independently. Different governmental agencies operating under different statutory directives were responsible for addressing the dangers from these carcinogens. As a result, different policies and practices were developed. This Article explores these differences and the record on resolving them. It first examines the history of federal regulation of chemical and radiological carcinogens and summarizes EPA's approach to risk assessments for them.

Editors' Summary: This Article addresses the effect of the U.S. Constitution's Takings Clause on the government's authority to protect environmental resources. An earlier Article, published in the May 1994 of ELR, analyzed bases for government regulation provided by limitations inherent in the property right itself. In contrast, this Article focuses on an emerging doctrine of sustainable use, rooted in background principles of nuisance law and the government's complementary police power.

Editors' Summary: Environmental regulation has come under increasing attack from those who argue that governmental limitations on property use violate constitutional restrictions on regulatory takings of property. The author addresses this controversy by focusing on the background limitations on owners' rights that are inherent in property law itself, as opposed to the external controls that government may impose under the doctrines of police power and nuisance.

Is an intentional temporary deprivation of the use of land not a "temporary taking"? This proposition was asserted by a panel of the U.S. Court of Appeals for the Ninth Circuit in Tahoe-Sierra Preservation Council, Inc. v. Tahoe Regional Planning Agency. The Ninth Circuit denied en banc review, despite a strong dissent by Judge Alex Kozinski. Perhaps because it had never explicated the meaning of "temporary taking," and perhaps in part because its interest was kindled by the Kozinski dissent, the U.S. Supreme Court recently granted certiorari. The question is limited to:

Editors' Summary: Property owners often respond to solid and hazardous waste contamination of their properties by cleaning up the contamination and then seeking reimbursement of cleanup costs from responsible parties under federal and state hazardous waste laws. RCRA is one such law; however, RCRA §7002 does not explicitly provide for recovery of damages. A court faced with a RCRA §7002 citizen suit to recover cleanup costs must imply a private cause of action for damages. This Article addresses the availability of a private cause of action for damages under RCRA §7002.

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.

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.
