Environmental Protection Agency (EPA) is granting a petition submitted by Lockheed Martin Aeronautics Company to exclude (or delist) the sludge from its wastewater treatment plant generated by Lockheed Martin Aeronautics Company in Fort Worth, Texas from the lists of hazardous wastes. This final rule responds to the petition submitted by Lockheed Martin Aeronautics Company to delist F019 sludge generated from the facility's wastewater treatment plant. After careful analysis and use of the Delisting Risk Assessment Software (DRAS), EPA has concluded the petitioned waste is not hazardous waste. This exclusion applies to 90 cubic yards per year of the F019 sludge. Accordingly, this final rule excludes the petitioned waste from the requirements of hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA) when it is disposed in a Subtitle D Landfill.
