In Environmental Federalism Part 1: The History of Overfiling Under RCRA, the CWA, and the CAA Prior to Harmon, Smithfield, and CLEAN, the history of judicial and administrative decisions relating to overfiling under the Resource Conservation and Recovery Act (RCRA), the Clean Water Act (CWA), and the Clean Air Act (CAA) was analyzed. The history showed that the U.S. Environmental Protection Agency (EPA), with limited exceptions, generally was understood to have overfiling authority under RCRA, the CWA, and the CAA. The limited exceptions focused on two situations.

In the span of just a few years, the U.S. Supreme Court has brought the venerable constitutional concept of federalism back to life with a vengeance. In the 1999 Term alone, the Rehnquist Court struck down three federal laws for violating basic principles of federalism and narrowly construed a fourth to avoid any conflict with those precepts.

Editors' Summary: In recent years, vindication of private-property rights has been the rallying cry of various citizen groups and politicians who believe that certain regulatory restrictions—especially environmental protection measures—have "gone too far" and that the Fifth Amendment is an insufficient safeguard of private-property rights.

On June 29, 2001, the last day of the October 2000 term, the U.S. Supreme Court granted certiorari to consider "whether the [Ninth Circuit] Court of Appeals properly determined that a temporary moratorium on land development does not constitute a taking of property requiring compensation under the Takings Clause of the [U.S.] Constitution?" The case, Tahoe-Sierra Preservation Council, Inc. v. Tahoe Regional Planning Agency, provides the Court with an opportunity to clarify its opinions in First English Evangelical Lutheran Church of Glendale v.

Editors' Summary: Pfiesteria piscicida, a sometimes toxic microorganism, is responsible for the death of millions of fish in Delaware, Maryland, North Carolina, and Virginia. Although the problem of Pfiesteria-related fish kills is associated with the Mid-Atlantic region, other toxic microorganisms have threatened fish and marine wildlife throughout the world. Scientists attribute this "global epidemic" of toxic microbes to excessive nutrient loading from nonpoint sources of pollution.

Editors' Summary: On June 29, 1998, EPA published its PCB Mega Rule, a comprehensive revision of TSCA regulations that govern the remediation and disposal of PCB-contaminated material. The PCB Mega Rule affords the regulated community the option of remediating such material under self-implementing provisions or developing risk-based site-specific remedial measures that generally require Agency approval.

Editors' Summary: After TSCA was enacted in 1976, some commentators described it as the most powerful of all the environmental laws. Congress intended it to provide for the comprehensive and direct control of commercial chemicals' potential health or environmental effects in a true cradle-to-grave tracking system. Indeed, it was the single law addressing toxic substances that could cover all areas of environmental regulation, supplementing sections of existing toxic substances laws. In the 17 years since its enactment, however, TSCA has not fulfilled these goals or expectations.

Editors' Summary: During congressional debate on CERCLA reauthorization, attention has focused on the role of states in executing the Act. Some observers of these debates have questioned the constitutionality of delegating EPA cleanup and enforcement authorities to states. In contrast, this Article argues that such delegation is permissible under the U.S. Constitution and constitutional jurisprudence. The author asserts that under the Appointments Clause, the delegation of CERCLA authorities to states would not usurp Executive Branch functions.

Editor's Summary: The exact contours of wetlands jurisdiction has been in dispute ever since the U.S. Supreme Court's decision in Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers. Today, the Court has been given the chance to clarify this area of law as it faces two cases dealing with wetlands jurisdiction. In Rapanos v. United States, the Court must decide whether CWA jurisdiction extends to a series of wetlands that do not abut a navigable-in-fact water. And in Carabell v. U.S.
