Services:

ASBESTOS/LEAD SURVEYS

Environmental Planning & Management, Inc. (EPM) conducted a survey of the areas associated with demolition of the Tappan Zee Bridge for suspected asbestos, lead paint, and PCB containing materials and collected bulk samples for lab analysis.

Areas of investigation included the NYS trooper barracks, movable barrier building, toll utility building, toll plaza, and a limited survey at both abutments of the bridge. Additional Hazardous Materials investigations included an asbestos survey at the Hot House west abutment under the Tappan Zee (on the Nyack side).

LEAD SURVEYS

EPM also performed supplemental sampling and analysis of paint from metal members of Span 179 of the existing Tappan Zee Bridge.

EPM performed a lead paint and asbestos containing materials (ACM) survey of the west abutment utility/electrical vault and Pier 1, and at the east abutment and east spans from Bent 198 to just beyond Bent 191.

ABATEMENT MONITORING

EPM provided asbestos project/air monitoring services during ongoing demolition activities.

UST REMOVAL

EPM documented the removal of one underground gasoline storage tank located at the former New York State Thruway Authority Maintenance Garage / Police Trooper Barracks. EPM was onsite to observe the tank removal procedures and to collect post excavation end point soil samples for laboratory analysis.

WASTE STREAM SAMPLING

EPM sampled demolition waste originating from Rockland Moveable Barrier Building to help characterize waste for disposal and recycling.

COMMUNITY AIR MONITORING (CAMP)

EPM performed Community Air Monitoring during excavation activity for construction of a chain link fence within the boundaries of the Tarrytown MGP Brownfield Site. The air monitoring was performed in general accordance with the Community Air Monitoring Plan (CAMP) requirements included in The Site Management Plan (SMP), Tarrytown Former MGP Site, Haley & Aldrich of New York. The CAMP monitoring was performed for the purpose of protecting the downwind community from exposure to potential airborne contaminants migrating from the work zone during installation of the chain link fence.

Challenge:

Containment of hazardous materials being abated over water.

Solution:

Strict inspection during raising of containment to ensure no weak spots or openings exist. Using extra poly sheathing as necessary to reinforce containment. Ensuring that all waste generated is securely bagged before removal from regulated work area.
