Thermal Treatment Projects

Boston Convention Center Remediation Project
Maxymillian Technologies (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 EPA and MA Department of Environmental Protection (MA DEP) regulators. This site cleanup was part of a public sector, highly fast-tracked brownfields project that had never before been attempted in New England.

This site was formally operated as a recycling facility that handled transformers and scrap metal. The primary contaminants were Polychlorinated Biphenyls (PCBs), lead, and solvents. Prior to conducting demolition work, MT characterized, categorized, consolidated and disposed of several unknown drums.

MT segregated, thermally treated, and disposed of 6000 tons of contaminated soils and debris. This involved TCLP Lead stabilization of soil and debris. MT also mobilized their Water Treatment System to treat ponded waters and dewatering liquids. The site was restored for future use after placing a temporary soil containment cap. On-site soil treatment with MT's thermal system, and soil stabilization measures saved the client over $6.5 million in hauling/treatment costs.

At several stages during the project, community concerns prompted MA 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.

MT maintained a highly accelerated, City-imposed schedule to meet Convention Center deadlines, that was initially considered unrealistic - even to the Owner. To successfully achieve this 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. MT's successful project completion reinforced a 30-year company reputation of highly responsive and reliable service.

"From the beginning to the completion of the project, MT's performance was excellent…The performance of Maxymillian's staff was outstanding. Due to the nature of the project, both EPA and MA DEP were both actively involved. This required MT's staff to submit plans and interact with regulatory personnel. MT's ability to explain technical aspects of the project in conjunction with providing updates on operational and monitoring activities was critical in gaining and maintaining the confidence of both MA DEP and EPA."

Remedial Site Operations:
  • Site clearance (i.e. clearing and grubbing the site vegetation).
  • Removed and treated ponded surface water.
  • Segregation and off-site disposal of 6000 tons of contaminated soils and debris.
  • Thermal treatment of several thousand tons of contaminated soil using the Indirect Desorption System (IDS).
  • TCLP Lead stabilization process of soil and debris.
  • Water treatment using system of: filter press, Rosedale filters, polymer bed, and liquid phase carbon treatment.
  • Direct rail transport of treated soil and debris to rail served disposal facilities.
  • Placed a temporary soil containment cap.
  • Restored site for future Convention Center activities.
