GZA provided demolition support to Gramercy USA for demolition of the 1960s-era Microstrainer Building at the Jerome Park Reservoir. The building was constructed of reinforced concrete floors, walls and roof with CMU interior walls. It comprises a below grade superstructure and an above-ground superstructure; components of which were known to be coated with a dried paint film that contained polychlorinated biphenyls (PCBs) in excess of 50 parts per million (PPM).
Challenge
GZA was asked to provide services in support of Gramercy’s Remedial Action Work Plan (RAP) to address environmental remediation, demolition, worker protection, and waste management.
Solution
GZA prepared a combined PCB and Lead Safe Work Plan—addressing worker protection practices and spread of lead and potential PCB contamination from surfaces with PCB concentrations less than 50 PPM—and PCB and Lead Management Plan—to address work procedures and equipment used during the disturbance, removal, handling and disposal of lead and PCBs from surfaces with concentrations greater than 50 PPM. The combined plan included procedures to conduct worker exposure monitoring and maintain clean/hygienic work areas; Safety Data Sheets for chemical products used; medical clearance, worker training and respirator fit-test information; task hazard analysis for activities with potential to disturb PCB-containing materials; a schedule and layout for key areas; information pertaining to collection, handling and disposal of PCB-containing and lead materials, equipment decontamination, emissions monitoring and control; identification of federal, state, and local permits required for recycling facilities and waste haulers accepting and transporting the PCB and lead waste.
Benefit
GZA’s input was critical to the contractor’s safe and successful implementation of the RAP.
