The purpose of The National Biennial RCRA Hazardous Waste Report (Based on 2001 Data) is to communicate the initial findings of EPA's 2001 hazardous waste reporting data collection efforts to the public, government agencies, and the regulated community. The Report consists of three volumes of data: - The National Analysis data presents a detailed look at waste-handling practices in the States, and largest facilities nationally, including (1) the quantity of waste generated, managed, shipped and received, and interstate shipments and receipts and (2) the number of generators and managing facilities, - The State Detail Analysis data is a detailed look at each State's waste handling practices, including overall totals for generation, management, shipments and receipts, as well as totals for the largest fifty facilities, and - The List of Reported RCRA Sites identifies every hazardous waste facility in the United States that submitted a hazardous waste report in 2001.
