Phase II of the Redevelopment of the Former Modern Electroplating Facility
Weston & Sampson was retained by the Boston Public Facilities Department (PFD) as the environmental consultant as part of Phase II of the redevelopment of the former Modern Electroplating Facility in Roxbury, Massachusetts. Weston & Sampson was hired to manage Massachusetts Contingency Plan (MCP) activities, contaminated soil and groundwater during construction, and design and provide oversight services for a vapor barrier and sub-slab depressurization system beneath the new police station.
The new police station was constructed at a site that was regulated under the MCP due to the presence of metals, cyanide, and chlorinated Volatile Organic Compounds (VOCs) in soil and groundwater. The release of oil and hazardous materials is attributed to operations at a former electroplating facility at the property.
Weston & Sampson conducted environmental consulting services and MCP response actions during design and construction, including:
- Preparation of soil and groundwater management plans and specifications for public bid.
- Design of vapor barrier and sub-slab depressurization system to mitigate potential vapor intrusion issues.
- Preparation of MCP documents to include Release Abatement Measure (RAM) Plan, Status Reports, and RAM Completion Report to manage contaminated soil and groundwater during construction.
- Construction oversight during soil excavation, dewatering activities, and installation of the vapor barrier and sub-slab depressurization system.
- Management of the removal, on-site reuse, and off-site recycling/disposal of over 20,000 tons of excavated material, including review and approval of disposal documentation and recycling/disposal facilities.
- Numerous meetings with Massachusetts Department of Environmental Protection (MA DEP) and correspondence with Environmental Protection Agency (EPA) to manage soil classified as F-Listed Hazardous Waste due to chlorinated VOC contamination.
- Weston & Sampson developed soil management strategies with MA DEP to minimize disposal costs.
- Obtained Beneficial Use Determination (BUD) permit from MA DEP to reuse coated brick and concrete from the demolished electroplating facility as backfill on-site to reduce construction costs and support LEED® certification for the new Police Station building.
