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: Since 1910, the federal government has played a role in regulating pesticides. At first, the motive was to fight fraud, but as pesticides became more sophisticated and as environmental concerns grew, the government's regulatory efforts became more comprehensive. Now, near the dawn of bioengineered pesticides, with society confronting and reevaluating environmental risks, and with agencies facing fiscal challenges, pesticide regulation continues to evolve. It is a field of concern to the pesticide industry, of course, but in U.S.

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.

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.

Editors' Summary: In 1989, a National Research Council study concluded that contaminated sediments are "widespread in U.S. coastal waters" and have "potentially far-reaching consequences to both public health and the environment." A 1996 interim EPA report reached a similar conclusion. This concern over contaminated sediments is not new. It has manifested itself in a dizzying array of statutory and regulatory restrictions on the disposal of these sediments.
