Editors' Summary: The recently completed 105th Congress provided the nation with a legacy of unparalleled legislative inactivity. Few, if any, of the legislative initiatives earmarked as priorities passed as bitter partisan debate ruled on Capitol Hill. This Comment analyzes how such partisanship and subsequent congressional lethargy created the environmental successes, controversies, and failures of the 105th Congress.

Over the past several years, considerable public and private efforts in this country have been directed at reducing the risk of cancer that human exposure to high levels of radon gas poses. These efforts appear to have succeeded in raising public awareness of radon and in increasing testing for radon. For the most part, however, these efforts have been directed toward homeowners and have not addressed the problem of radon in residential rental properties. Yet, in 1989, nearly 34 million homes—over one-third of all housing units in the country—were rental units.

Although the 104th Congress did not begin officially until January 4, 1995, its significance was apparent as soon as the polls closed on November 8, 1994. When the votes were tallied, Republicans had acquired majorities in both the Senate and the House for the first time in 40 years. And they were quick to proclaim the beginning of a revolution in congressional lawmaking.

Editors' Summary: It has become regular practice for federal legislators to insert into annual appropriations bills riders having little to do with the appropriations process. Last year, under the sponsorship of the Senate Majority and Minority Leaders, a bill that would have exempted recyclers from CERCLA "arranger" and "transporter" liability was almost enacted as a rider to the omnibus appropriations bill for fiscal year 1999. This Dialogue examines that rider and the changes it would have wrought to CERCLA.

Editors' Summary: One of the most important legal tools in the effort to remediate the nation's contaminated sites is state law that applies to such cleanups. In 1989, the Environmental Law Institute (ELI) conducted a study of this law, and last year, it completed its most recent update of that study. In this Article, two ELI Senior Attorneys discuss the results of that update as it concerns two key aspects of site remediation—voluntary and brownfield cleanup programs.

In the past few years, owners of contaminated land, seeking to supplement possible causes of action under the Comprehensive Environmental, Response, Compensation, and Liability Act (CERCLA) and under state common law and state statutes, increasingly have looked to §7002(a)(1)(B) of the Resource Conservation and Recovery Act (RCRA) to shift responsibility for remediation costs to former owners or operators.

A more substantive precautionary principle of international law is evolving as new treaties articulate new measures of precaution in different contexts. Although there is considerable controversy over how to articulate or define a precautionary "principle" of law, the goal is to ensure that the mere lack of scientific knowledge about risks cannot justify a failure to take appropriate precautions. Where we have sufficient evidence of risk, we often take precautions, despite a lack of certainty about those risks.

In a recent article reviewing the U.S. Supreme Court's environmental decisions over the last 30 years (1969-1999), Professor Richard Lazarus argues that "the Justices have never fully appreciated environmental law as a distinct area of law."¹

The 1999 National Nuclear Security Administration Act (NNSA Act) threatens to reverse 20 years of reforms and court decisions intended to bring the U.S. Department of Energy (DOE) into compliance with environmental laws and regulations. The NNSA Act, enacted in the wake of allegations of spying at Los Alamos nuclear weapons laboratory in New Mexico, established a semi-autonomous agency within DOE—the National Nuclear Security Administration (NNSA). The NNSA operates nine laboratories and facilities within the U.S. nuclear weapons complex.

The Resource Conservation and Recovery Act (RCRA), the Clean Water Act (CWA), and the Clean Air Act (CAA) represent federal regulatory regimes for protecting the environment. Although each statute initially places administrative responsibility in the hands of the U.S. Environmental Protection Agency (EPA), each encourages states, to varying degrees, to take primary responsibility for implementing the statutory regime.
