RCRA Cleanup Reforms (EPA 530-F-99-018). This Fact sheet was issued by the U.S. EPA Office of Solid Waste. Since 1984, EPA and authorized states have made considerable progress in implementing the Corrective Action requirements. Despite the progress made, states, environmental groups, and the regulated community have raised concerns, including: slow progress in achieving cleanup or other environmental results; an emphasis on process and reports over actual work in the field; unrealistic, impractical or overly conservative cleanup goals; and lack of meaningful public participation. Because of various reasons raised by many stakeholders, the Agency believes that it is time for a fundamental re-evaluation of its Corrective Action Program. This re-evaluation comes in the form of the RCRA Cleanup Reforms [July 1999, 4 pages]. View or download at http://www.epa.gov/epaoswer/osw/factsheet1.pdf .

The National Biennial RCRA Hazardous Waste Report (Based on 1997 Data). The United States Environmental Protection Agency (EPA), in partnership with the States, biennially collects information regarding the generation, management, and final disposition of hazardous wastes regulated under the Resource Conservation and Recovery Act of 1976 (RCRA), as amended. The purpose of The National Biennial RCRA Hazardous Waste Report (Based on 1997 Data) is to communicate the findings of EPA’s 1997 Biennial Reporting System (BRS) data collection efforts to the public, government agencies, and the regulated community. The Report consists of six volumes which include: Summary Report, National Analysis, State Summary Analysis, State Detail Analysis, List of Large Quantity Generators, and List of Treatment, Storage and Disposal Facilities. All of the volumes can be viewed or downloaded at http://www.epa.gov/epaoswer/hazwaste/data/br97/index.htm .

From Cleanup to Stewardship (DOE/EM-0466). This document, produced by the U.S. Department of Energy is a companion to its Paths to Closure. It provides information on DOE’s long term stewardship obligations and activities. Long term stewardship is expected to be required at more than 100 sites after DOE’s environmental management program completes disposal, stabilization and restoration operations to address hazardous was and contamination [October 1999, 102 pages].
