The Superfund tax, which funded the program, expired 1995 and has not been renewed.
Critics argue that Superfund needs a complete overhaul and many bills have emerged to that effect.
Program supporters admit that specific sections need amendment, including the Superfund trust fund, brownfields sections, and issues of liability and clean-up standards. Congressional dispute, mainly down party lines, has divided bills into those for a comprehensive Superfund reform, and those concerned with sections of the statute. Congressional Research Service Reports provide in depth summary of the Superfund situation can also be found at the National Council for Science and the Environment website. The purpose of S. 2700, the Brownfields Revitalization and Environmental Restoration Act of 2000, is to promote the cleanup and reuse of brownfields, to provide financial assistance for brownfields revitalization, and to enhance state response programs. One explanation for the continued freeze on Superfund reform legislation came out on July 1, 2000.
