The Society of American Military Engineers (SAME) Denver Post and Philadelphia Post along with the US Environmental Protection Agency (EPA) are hosting a series of webinars based on talks given at recent Design and Construction Issues at Hazardous Waste Sites (DCHWS) Symposiums. The mission of the DCHWS symposiums is to facilitate an interactive engagement between professionals from government and the private sector related to relevant and topical issues affecting applications of engineering and science associated with cleaning up hazardous waste sites. The symposiums also serve as a platform to facilitate the exchange of information, encourage dialogue, share experiences, and build and enhance communication among design and construction professionals. This presentation will highlight work at the BICC Cables Site, a former cable manufacturing facility whose operation led to contamination of on-site soil and sediment by polychlorinated biphenyls (PCBs), has been the subject of remediation efforts since 2005. The impacted sediment could not be efficiently and safely removed by dredging as a result of horizontal and vertical spatial limitations, safety concerns, and the heavy debris content. Therefore, an engineering control was required to contain and treat the PCB impacted sediment. In addition to the engineering challenges posed by the site conditions, the need to work within the waters of the Hudson River created an extremely complex regulatory context. The presentation will discussion a Multi-Layer Sediment Cover System (SCS) engineering control which was designed and implemented to contain and treat the PCB-impacted sediment under the 29,500-square-foot EPRI Building in the Hudson River. In addition, SCS Remote Sensing System load cells with fiber optic cables were installed to monitor long-term movement and integrity of the SCS. Proactive stakeholder engagement was necessary to navigate the project through the two-year permitting process by leading numerous design presentations and negotiation sessions with the five regulatory agencies. Routinely adjusting the installation approach and construction schedule were also necessitated by the nature of working in a dynamic water body.
