BGI has provided sampling, waste management, and environmental support services for this characterization, remediation, and decontamination and decommissing (D&D) of underground industrial waste lines, tanks, and underground structures for the Technical Area (TA) 21 Delta Prime Site Aggregate Area Delayed Sites project. Sampling scope included supporting the investigation of the soils beneath the footprint of Building 21-257 being demolished as part of this project. Sampling was conducted in accordance with the “Investigation Work Plan for Delta Prime Site Aggregate Area Delayed Sites, Revision 1” and the “DP Site Aggregate Area Building 21-257 Footprint Letter Work Plan”. Soils and tuff were sampled to determine if they were suitable for reuse (i.e., not hazardous waste and met residential soil screening levels and screening action levels). Samples were located using GPS. BGI’s Environmental Professional was on-site supporting operations to prevent and mitigate adverse environmental impacts and to ensure operations were in compliance with N3B’s requirements. He provided environmental protection/compliance training for new employees ensuring environmental requirements and goals were clear, and he conducted environmentally related pre-job briefings. He continuously evaluated the site for environmental protection/compliance related issues, interfaced with N3B environmental personnel and the Senior Technical Representative to resolve environmental issues, initiated measures to mitigate identified issues, and updated documents accordingly. He conducted and documented daily environmental inspections and ensured specific environmental controls were maintained throughout the project. BGI is preparing project reporting deliverables including the Final Project Closeout Report, Shipping Determination and Characterization Summary Report, and Integrated Work Completion Packages in addition to maintaining and organizing the project characterization analytical results database and project team training documentation database.
