The Environmental Protection Agency (EPA) today is granting a petition submitted by Aluminum Company of America (Alcoa), Pittsburgh, Pennsylvania, to exclude (or ``delist'') certain solid wastes generated by its wastewater treatment plant from the lists of hazardous wastes contained in subpart D of 40 CFR part 261. EPA has concluded that the petitioned waste is not a hazardous waste when disposed of in a subtitle D landfill. This exclusion applies only to the 16,772 cubic yards of wastewater treatment plant (WWTP) sludge present in the Stolle landfill. Today's action conditionally excludes the petitioned waste from the requirements of the hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA) only if the waste remains in place or, if excavated, it is disposed of in a subtitle D landfill which is permitted, licensed, or registered by a State to manage industrial solid waste.
