Dispose of all lead- contaminated soil and associated waste in compliance with federal, State, and local requirements. All samples must show that the soil meets the requirements in Paragraph 1.02B for work to be accepted by the Contracting Officer Representative.

3.3.2 Cleanup

Maintain surfaces of the lead control area free of accumulations of lead. Restrict the spread of dust and soil; keep waste from being distributed over work area. Do not remove the lead control area and warning signs prior to the Contracting Officer Representative's Representative approval.

3.4 TRANSPORTATION AND DISPOSAL

Furnish labor, materials, and equipment necessary to store, transport, and dispose of lead contaminated material in accordance with Federal, State, and local requirements. Prepare and maintain waste shipment records and manifests required by the Resource Conservation and Recovery Act (RCRA), U.S. Federal Department of Transportation (DOT), and State transportation department.

Prepare hazardous waste manifests for each shipment of hazardous waste shipped offsite. Manifests shall be completed using instructions in 40 CFR 262, Subpart B and any applicable state or local law or regulation. Submit manifests and waste profiles to Contracting Officer Representative for review and approval. Prepare land disposal restriction notifications as required by 40 CFR 268 or any applicable state or local law or regulation for each shipment of hazardous waste. Submit notifications with the manifest to the Contracting Officer Representative for review and approval.

3.4.2 Disposal

1. All material shall be disposed in accordance with all laws and provisions and all federal, State or local regulations.

2. Ensure all waste is properly characterized based on TCLP analysis of the excavated material. Testing frequency will be in accordance with disposal facility requirements.

4. Contractor is responsible for segregation of waste as required by the disposal facility. Collect lead- contaminated waste, scrap, debris, bags, containers, equipment, and lead-contaminated clothing that may produce airborne concentrations of lead particles. Label the containers in accordance with 29 CFR 1926.62 and 40 CFR 261.

5. Dispose of lead-contaminated material classified as hazardous waste at an EPA approved hazardous waste treatment, storage, or disposal facility off Government property.

6. Store waste materials in U.S. Department of Transportation (49 CFR 178) approved 55 gallon drums or approved sealed containers. Properly label each drum or container to identify the type of waste (49 CFR

172) and the date the drum or container was filled. For hazardous waste, the collection drum or container requires marking/labeling in accordance with 40 CFR 262 during the accumulation/collection timeframe. Until waste is characterized, handle all excavated soil as a hazardous waste. The Contracting Officer Representative or an authorized representative will assign an area for interim storage of waste-containing drums or containers. Do not store hazardous waste drums in interim storage longer than 90 calendar days from the date affixed to each drum.

7. Handle, store, transport, and dispose lead-contaminated soil waste in accordance with 40 CFR 260, 40 CFR 261, 40 CFR 262, 40 CFR 263, 40 CFR 264, and 40 CFR 265. Comply with land disposal restriction notification requirements as required by 40 CFR 268.
