In November 1995, five federal agencies—the U.S. Army Corps of Engineers (the Corps), the U.S. Environmental Protection Agency (EPA), the Natural Resources Conservation Service, the U.S. Fish and Wildlife Service (FWS), and the National Oceanic and Atmospheric Administration—issued joint guidance concerning wetland mitigation banking. The guidance's chief virtue is its detailed explanation of the approval process for the establishment and operation of mitigation banks. Its chief flaw, however, flows from the complexity of this approval process.

Earlier this year in KFC Western, Inc. v. Meghrig, the U.S. Court of Appeals for the Ninth Circuit ruled that private parties may obtain restitution of the costs of cleaning up contaminated property under §7002(a)(1)(B) of the Resource Conservation and Recovery Act (RCRA). The Ninth Circuit's ruling in KFC Western opened the way for private parties to use the RCRA citizen suit provision to recover their costs of investigating, studying, and cleaning up contaminated property from responsible parties.
