The Environmental Protection Agency (EPA or Agency) today is granting a petition submitted by Tyco Printed Circuit Group, Melbourne Division, Melbourne, Florida, (Tyco), formerly Advanced Quick Circuits, L.P., to exclude (or "delist") a certain hazardous waste from the list of hazardous wastes under RCRA regulation. Tyco generates the petitioned waste by treating liquid waste from Tyco's printed circuit board manufacturing processes. The waste so generated is a wastewater treatment sludge that meets the definition of F006. Based on careful analyses of the waste-specific information provided by the petitioner, the Agency has concluded that Tyco's petitioned waste will not adversely affect human health and the environment. This action responds to Tyco's petition to delist this waste on a "generator-specific" basis from the hazardous waste lists, and to public comments on the proposed rule. In response to comments received on the proposed rule, the delisting levels in this final rule are based, in part, on the EPACML model, rather than the generic levels for high temperature metal recovery residues. In accordance with the conditions specified in this final rule, the petitioned waste is excluded from the requirements of hazardous waste regulations under Subtitle C of the Resource Conservation and Recovery Act (RCRA).
