Demolition of 115 River Road Building

115 River Road Building

Soil remediation at the Quanta Resources Superfund Site has been suspended pending demolition of the 115 River Road Building (not including the pier building). This update provides an overview of the demolition.

The 115 River Road Building is a two-three story former industrial building extending from the Hudson River to River Road. It was constructed over time as a series of nine structures that appear to be one building. Honeywell is overseeing the demolition of this property.

Demolition is planned in sections, working east to west, from the Hudson River toward River Road.

NorthStar, the abatement contractor, has certified that asbestos and waste have been completely removed.

Only the building itself will be demolished. All sub-surface areas will be left in place and will be addressed when soil remediation resumes.

Air Monitoring During Demolition

Demolition will generate dust, which will be controlled using tools that spray water to the demolition area.

Although not required by local, state, or federal ordinances, a community air monitoring plan, approved by the United States Environmental Protection Agency, will be implemented during demolition.

Eight “real-time” fixed air monitors at the perimeter will measure dust with “alert” and “action” levels. The placement of the monitors provide coverage for wind coming from any direction.

Action Levels: Air quality parameters are established at 150 μg/m3 based on a 24-hour average exposure using the National Ambient Air Quality Standard. For this project a more conservative action level of 150 μg/m3 over a 15-minute average will be used.

Alert Levels: An early warning level (100 μg/m3) over a 15-minute period.

If Alert Levels are met, additional water will be applied; if Action Levels are met work will stop until the dust is reduced.

Results of air monitoring for dust during demolition, which began on September 12, 2018, can be found on the interactive map below. In addition, dust suppression techniques are being implemented during demolition.

Building Demolition

Demolition will be completed in accordance with all applicable laws and ordinances, and with required state and Borough of Edgewater permits and inspections. It will be done by the property owner and includes the following:

  • Rodent abatement and control - Demolition activities will potentially disturb existing rodent populations. A licensed exterminator will be responsible for removing rodents before, during, and after demolition. Honeywell has directed the contractor to exceed its standard practices to maximize rodent control.
  • Utility disconnection and relocation, as needed (water, sewer, gas, electric, and communications)
  • Dust Control - Demolition will generate dust. Dust will be controlled using tools that spray water, tools equipped with local exhaust ventilation, and by spraying the demolition area with water.
  • Fencing - Fencing will be installed around the demolition area to manage access.
  • Stormwater management
  • Soil erosion and sediment control
  • Flood control


September - Demolition will move from east to west, from the river to the road.

Demolition is expected to take approximately three months.
