Boston Convention Center Remediation Project

MT was contracted by the Boston Redevelopment Authority to conduct fast tracked contaminated material treatment/disposal for the future Boston Convention & Exhibition Center. The site was located in a heavily populated industrial/urban area of South Boston and involved daily, intensive interaction with USEPA and Mass DEP regulators.

The primary contaminants at the site were PCBs, lead, and solvents. Prior to conducting demolition work, MT characterized, categorized, consolidated and disposed of several unknown drums. MT then segregated, thermally treated, and disposed of 6000 tons of contaminated soils and debris, including performing TCLP Lead stabilization. MT also mobilized our Water Treatment Systems to treat ponded waters and dewatered liquids.

At several stages during the project, community concerns prompted Mass DEP and EPA to request additional data and air quality management. MT worked closely with the regulators to develop a timely response which satisfied all parties involved.

To help achieve the highly accelerated, City-imposed schedule, MT used rail cars that were site accessible, worked weekends, and operated the thermal system 24 hours a day. In addition, to work within the limited available land area, MT conducted several site activities simultaneously, under very tight spatial constraints. In choosing on-site thermal treatment, the client saved $6.5 million in transport/treatment costs.

"MT's ability to explain technical aspects of the project… was critical in gaining and maintaining the confidence of both Mass DEP and EPA… From the beginning to the completion of the project, MT's performance was excellent."
