E2PM has been involved with this project from initial due diligence through the preparation of remedial designs for remediation, and most recently remediation contractor bid evaluation and selection. The former Van Leer Chocolate Company site is located in Jersey City, Hudson County, New Jersey. The site consists of two parcels – the north parcel (4.2 acres) and the south parcel (3.7 acres). Historical manufacturing activities at the site included the production of weed control products, paints, lacquers, brick seal, soap and chocolate. The Van Leer Corporation began manufacturing chocolate at the site in 1949.
Sixteen Areas of Concern (AOC) have been identified for the site, including historic fill, fuel oil underground storage tanks (USTs), a vertical waste oil UST, on-site groundwater, south parcel arsenic contamination, a New Jersey Transit Right-of-Way (ROW) and a City of Jersey City pump station. Specific contaminants observed on the north parcel exceeding applicable NJDEP standards include VOCs in soil and metals, VOCs and SVOCs in groundwater. Specific contaminants observed on the south parcel exceeding applicable NJDEP standards include metals, VOCs and SVOCs in both soil and groundwater. The south parcel, where the majority of remedial activities are proposed, is located within the Jersey Avenue Redevelopment Plan Area (RPA).
E2PM has assisted in evaluating the remedial measures of elevated arsenic contamination, with consideration on redevelopment plans for excavation, shoring, dewatering and construction of subsurface foundations. E2PM has supported our client (the Hudson Brownstone Company) on financial funding opportunities, Brownfield Cost Reimbursement, proposed engineering cap designs, and the development of a soil management plan that formed the basis of remediation bid specifications distributed to prospective bidders.
Site contamination requires carefully coordinated Health & Safety and construction management plans, strict dust controls, avoidance of public utilities during excavation and construction, and understanding of architecture and engineering controls to prevent worker, future resident and public contact with site contaminants.
The proposed, NJDEP-approved remedial approach for the site includes on-site treatment (stabilization) and off-site disposal of the arsenic-impacted soils, as well as appropriate engineering and institutional controls. The approved remedial approach specifically requires the excavation of arsenic-impacted soils above a site-specific cleanup standard, to a depth of 16 feet, disposal of hazardous and non-hazardous soils off-site, dust controls during excavation, installation of engineering controls (i.e. cap installation), and establishment of a Deed Notice and a site-wide CEA. Remedial activities are expected to begin in late 2016.
