One of the more daunting tasks facing environmental practitioners over the past decade or two has been the recovery of cleanup costs and related relief at sites contaminated with petroleum substances. Parties seeking relief face significant hurdles under the federal environmental statutes. The key federal environmental cost-recovery statute, the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) often provides little help because of its petroleum exclusion.

Buried deep within the several thousand page Omnibus Consolidated Appropriations Act signed by President Clinton in the waning days of the 104th Congress are the first significant amendments in a decade to the much-debated Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). CERCLA is the federal law that creates a broad class of parties potentially liable for expenses incurred in cleaning up sites contaminated with hazardous substances.

The federal courts are in agreement that an action by a potentially responsible party (PRP) against another PRP to recover privately incurred response costs is a claim for contribution in which the plaintiff is limited to the relief that is available under §113(f)(1) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

Editors' Summary: Environmental professionals continue to consider the implications of the 2006 U.S. Supreme Court landmark decision regarding CWA jurisdiction, Rapanos v. United States. In this Article, Matthew A. Axtell uses Justice William O. Douglas'travel description of Alaska's Last Lake as a hypothetical to test the potential impact of the 2001 SWANCC decision as well as Rapanos on the federal government's CWA authority in Alaska. He begins by analyzing the CWA regulatory regime that applied for many years to Alaskan tundra wetlands before SWANCC and Rapanos.
