In two major Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) opinions, United States v. Atlantic Research, Inc. and Burlington Northern & Santa Fe R.R. v. United States, the U.S. Supreme Court provided long-sought guidance for parties litigating hazardous waste cleanup issues under CERCLA.

On May 4, 2009, the U.S. Supreme Court handed down its decision in Burlington Northern & Santa Fe Railway Co. v. United States. The decision is of major significance with respect to two areas of Superfund jurisprudence--"arranger" liability, and divisibility or apportionment of harm. This Article is concerned only with the latter issue and, moreover, only with one specific element of that issue.

This past May, the U.S. Supreme Court for the first time addressed two issues that the U.S. Congress left open in the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). These issues are: (1) the scope of "generator" or "arranger" liability under the language of CERCLA §107(a)(3); and (2) the circumstances under which a liable party under §1073 may be held jointly and severally liable. Rejecting the position of the U.S.

There can be no sustainable development without sustainable transportation. It is an essential component not only because transportation is a prerequisite to development in general but also because transportation, especially our use of motorized vehicles, contributes substantially to a wide range of environmental problems, including energy waste, global warming, degradation of air and water, noise, ecosystem loss and fragmentation, and desecration of the landscape. Our nation's environmental quality will be sustainable only if we pursue transportation in a sustainable way.

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.

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.

If we want to think about changes in local sustainability over the last 10 years, perhaps the best place to start is with Al Gore. In 1992, just before the Rio Earth Summit and before he was to be tapped as a vice presidential candidate, then-Senator Gore published a treatise on the environment called Earth in the Balance.
