Hazardous Waste Management System; Identification and Listing of Hazardous Waste Proposed Exclusion

Riepilogo

The EPA (also, "the Agency" or "we" in this preamble) is proposing to grant a petition to exclude or "delist" wastewater treatment sludge from conversion coating on aluminum generated by the Ford Motor Company (Ford) Kansas City Assembly Plant (KCAP) in Claycomo, Missouri from the requirements of hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA). This proposed exclusion, if finalized, conditionally excludes the petitioned waste from the requirements of hazardous waste regulations under RCRA. This petition was evaluated in a manner similar to the expedited process developed as a special project in conjunction with the Michigan Department of Environmental Quality (MDEQ) for delisting similar wastes generated by a similar manufacturing process. See 76 FR 10341, March 7, 2002. Based on an evaluation of waste-specific information provided by Ford, we have tentatively concluded that the petitioned waste from KCAP is nonhazardous with respect to the original listing criteria and that there are no other factors which would cause the waste to be hazardous. This exclusion, if finalized, would be valid only when the sludge is disposed of in a Subtitle D landf
