The document below is the “Treatability Studies Sample Exclusion Rule.” The rule conditionally exempts small scale treatability studies from Resource Conservation and Recovery Act (RCRA) Subtitle C regulation. EPA updated the rule in 1994, and the principal change to the existing rule was to increase the quantity of contaminated media which are conditionally exempt from Subtitle C regulation, when used in conducting treatability studies.You may need a PDF reader to view some of the files on this page.
