Editors' Summary: Congress first addressed the problem of leaking underground storage tanks (USTs) in 1984, by enacting Subtitle I of RCRA. The UST regulatory program addresses, inter alia, corrosion protection, reporting, corrective action, and financial responsibility. In this Article, the author provides an overview of the federal UST program. The author outlines the program's significant elements and explores specific regulations in the context of the technical problems they are intended to address, giving particular attention to how, to what, and to whom the regulations apply.

Water policy in the United States has been significantly influenced in recent years by a number of high-profile environmental and water use conflicts, including disputes relating to California's Bay Delta, Florida's Everglades, the management of the Colorado River system, the Columbia/Snake system, and the Klamath and Trinity River Basins. For a variety of legal, institutional, and financial reasons, the federal government has played a major role in all of these matters, typically in partnership with state and local stakeholders.

 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.

One of the most fundamental tenets of toxicology is that "the dose determines the poison." This simple phrase provides the basis for the belief that all agents—chemicals and physical phenomena that are capable of producing some effect—have the potential to cause toxicity. Whether toxicity actually occurs is principally a matter of dose: the greater the exposure to a given agent, the more pronounced or severe the response of a cell or organism.
