Challenge
This 20-acre brownfield site straddled two townships, comprised two parcels separated by a railroad line, was adjacent to wetlands, and had been used for chemical manufacture and storage for 85 years. GZA was retained to close this complex New Jersey Industrial Site Recovery Act (ISRA) case which had been initiated prior to our clients’ involvement.
Solution
GZA’s broad range of services began with due diligence and have included a Phase I Environmental Site Assessment (including groundwater investigation and monitoring well installation), Brownfield Designation Services (including a remediation cost estimate), site/civil work, a Redevelopment Plan, extensive permitting with numerous entities, geotechnical investigation, a wetlands survey, a pre-demolition asbestos-containing materials (ACM) survey and Hazardous Materials Inventory (HMI), environmental support during construction (including assessment of excavated soils for disposal and remediation), UST removal, and a Remedial Action Workplan. GZA closed out one ISRA case and established soil institutional controls, allowing development to proceed. Both parcels were redeveloped as freezer facilities.
GZA subsequently completed surface water, sediment, porewater, and toxicity sampling to evaluate potential historical impacts to the adjacent tributary from the former chemical manufacturer. Evaluation of potential surface water and sediment impacts is on-going.
Benefit
GZA’s multi-disciplinary team developed effective solutions for the client at every stage of the property transaction and development and continues to effectively address regulatory and compliance obligations at the site.
