Editors' Summary: More than most areas of law, Congress looms large over environmental law. Federal environmental statutes, and the appropriations that fund them, serve as the central vein from which most areas of environmental law branch out. The 101st Congress in 1989 and 1990 was one of the most environmentally active congresses in two decades. From the Clean Air Act to the Oil Pollution Act to more criminal investigators at EPA, Congress strengthened environmental laws in a host of areas. At the same time, most of the laws are not self-implementing, and the stage is set for continued struggles in the months ahead. This Comment traces the accomplishments of the 101st Congress. First, it recounts events chronologically, from January 1989 through adjournment in October 1990. Then, it analyzes the results by subject in key environmental areas. Finally, it looks ahead to 1991, suggesting likely issues for the 102nd Congress.
