The U.S. Environmental Protection Agency Office of Solid Waste (OSW) is responsible for implementing and maintaining the RCRAInfo database. This database stores RCRA Subtitle C hazardous waste information including handler, permit, corrective action, compliance monitoring and enforcement, and biennial report. DPRA’s support to OSW for the RCRAInfo system includes development of on-line help, designing and implementing national reports, responding to ad-hoc report requests, assuring data quality, and independently testing the RCRAInfo application. DPRA’s strong knowledge of RCRA assists in identifying data anomalies, providing meaningful reports, and developing useful documentation.
