The State Authorization Tracking System (StATS) is an information management system designed to document the progress of each state and territory in establishing and maintaining RCRA-authorized hazardous waste management programs. StATS tracks the status of each state with regard to changes made to the federal hazardous waste regulations. The pages listed at the website show state authorization and adoption information for RCRA Subtitle C hazardous waste rules. Adoption information is based on data received from EPA regional offices. Currently, state authorization and adoption percentages are based on the required rules promulgated through RCRA Cluster XXII. Published federal register notices are the only legal mechanism by which EPA grants authorization to the states. If any of the information contained in the StATS database conflicts with information stated in the Federal Register, the Federal Register information will take precedence. We strongly recommend that the regulated community contact their state government office for hazardous waste regulatory information.
