Editors' Summary: For the past quarter century, the Clean Water Act has primarily relied on technological standards to abate point source pollution and achieve national clean water goals. Water quality standards lay largely dormant until the 1990s, when they were activated by citizen suits demanding implementation of §303(d) of the Act—the abatement of pollution discharges based on total maximum daily loads.

Editors' Summary: The Clean Water Act is undergoing a dramatic shift toward water quality-based regulation. Leading the charge, and taking their share of opposing fire, are the long-dormant provisions of §303(d) calling for the development of total maximum daily loads (TMDLs) for impaired waters. Earlier Articles in this series described the legislative and regulatory history of TMDLs, the litigation surrounding them, and the Administration's current efforts to redesign the program. This final Article attempts to step back and assess the potential of the TMDL program.

The U.S. Environmental Protection Agency (EPA) is in the process of redesigning the Clean Water Act's (CWA's) total maximum daily load (TMDL) program. Section 303 of the Act requires states and, if necessary, EPA to: (1) identify waters that do not meet water quality standards; (2) establish the TMDLs for pollutants discharged into these waters that will achieve these standards; and (3) incorporate these loads into state planning. These are of course the classic steps of ambient-based water quality management.

When the 103d Congress convened on January 5, 1993, many observers believed that it would make up for the dismal environmental record of its predecessor. The 102d Congress had tried and failed to reauthorize the Federal Water Pollution Control Act (FWPCA), the Endangered Species Act (ESA), and the Resource Conservation and Recovery Act (RCRA). Its attempt to elevate the U.S. Environmental Protection Agency (EPA) to a cabinet-level department had been blocked in the House of Representatives, and its attempt to reform the General Mining Law of 1872 had been blocked in both houses.

Editors' Summary: Until recently, the regulation of chemical carcinogens and the regulation of radiological carcinogens developed independently. Different governmental agencies operating under different statutory directives were responsible for addressing the dangers from these carcinogens. As a result, different policies and practices were developed. This Article explores these differences and the record on resolving them. It first examines the history of federal regulation of chemical and radiological carcinogens and summarizes EPA's approach to risk assessments for them.

Editors' Summary: Since 1910, the federal government has played a role in regulating pesticides. At first, the motive was to fight fraud, but as pesticides became more sophisticated and as environmental concerns grew, the government's regulatory efforts became more comprehensive. Now, near the dawn of bioengineered pesticides, with society confronting and reevaluating environmental risks, and with agencies facing fiscal challenges, pesticide regulation continues to evolve. It is a field of concern to the pesticide industry, of course, but in U.S.

Offshore areas are under pressure to industrialize for renewable energy. To plan for offshore wind development, Rhode Island engaged in a marine spatial planning process that resulted in the Ocean Special Area Management Plan (O-SAMP), a regulatory invention of the Coastal Zone Management Act. Notably, the Rhode Island O-SAMP maps and plans for uses in federal waters beyond the three-mile line dividing state and fedeal jurisdiction, as well as within the state's territorial sea, posing a challenge to the boundaries of offshore federalism.
