The product contains data compiled by the Biennial Reporting System (BRS) for the 'National Biennial RCRA Hazardous Waste Report (Based on 1997 data).' The data were collected by states using the '1997 National Hazardous Waste Report Instructions and Forms' (EPA Form 8700-13-A/B), or the state's equivalent information source. Data submitted by states prior to December 31, 1997 are included. Data for reports protected by RCRA Confidential Business Information (CBI) claims are not included. These data are preliminary and will be replaced by the final data. The data contain information describing the RCRA wastes generated and/or managed during 1997 by RCRA Treatment, Storage and Disposal Facilities (TSDFs) and RCRA Large Quantity Generators (LQGs). Data are reported by sites meeting the LQG and/or TSDF definitions. Sites are identified by their EPA/RCRA identification number. Response codes match those of the '1997 Hazardous Waste Report: Instructions and Forms' (EPA Form 8700-13-A/B).
