VERTEX was retained by a national, multi-family housing developer to provide full-scale environmental services for redevelopment of a former city hall and police station, constructed circa 1975, and a former church, constructed circa 1934, into a multi-family housing complex.
As part of environmental Due Diligence activities completed at the site, VERTEX completed a Phase I Environmental Site Assessment (ESA), a Phase II Limited Subsurface Investigation (LSI), and Pre-Demolition Survey. During the Phase I ESA, VERTEX identified the historical presence of on-site coal storage, two automotive repair facilities, shops (including an upholsterer, carpet cleaner, and dry cleaner), evidence of building fires, and historical and current evidence of four underground storage tanks (USTs). To assess these concerns, VERTEX completed a Phase II LSI which included the collection of soil and groundwater samples at select locations of the site. The results of the Phase II LSI identified polynuclear aromatic hydrocarbon (PAH)-impacted soil under the parking garage at the police station, which require response actions under the Massachusetts Contingency Plan (MCP). The results of the Pre-Demolition Survey identified significant asbestos-containing building materials (ACM) within the church building as well as ACM and polychlorinated biphenyl (PCB) caulking in the city hall and police station buildings.
As part of redevelopment activities, the city hall, police station, and church buildings will be demolished. VERTEX has prepared hazardous materials design specifications for the removal of ACM and PCB caulking. VERTEX will provide environmental monitoring during demolitions, including the implementation of a community air monitoring program and asbestos monitoring. Additionally, VERTEX will conduct a PCB sampling program in accordance with USEPA 40 CFR Part 761 Subparts N and O.
During demolition activities, VERTEX will also provide Licensed Site Professional (LSP) services under the MCP to remediate the PAH-impacted soil located under the police station garage. Specifically, VERTEX prepare a Release Abatement Measure (RAM) Plan and a Soil Management Plan and will oversee excavation activities and conduct disposal characterization sampling for the PAH-impacted soil. VERTEX will prepare disposal facility acceptance letters, LSP Opinion Letters, and associated waste manifest forms. VERTEX will also oversee the removal of on-site USTs from the site. The goal of the project is to file a Permanent Solution Statement with the MassDEP indicating a condition of No Significant Risk has been achieved and an activity and use limitation (AUL) is not required. Additionally, VERTEX will work with client to determine eligible costs of remediation under the Massachusetts Brownfield Tax Credit Program.
