NYC DEP WTC Program overview and components, n.d.

NYC 9/11 Public Portal Document

• DEP’s Exterior Clean Up Program was developed with funding from FEMA to clean up exterior surfaces of buildings that still had WTC debris. DEP staff developed scopes of work for the clean up and air monitoring. The Exterior Clean Up Program was initiated on June 3, 2002.

• Three abatement contractors, chosen through the City’s procurement process, conducted the exterior cleaning of building surfaces under DEP’s direction and oversight. A third party air-monitoring firm, also chosen through the City’s procurement process, performed air sampling during clean up activities. The clean up work included installing barriers, collecting all bulk debris, HEPA vacuuming and wet wiping surfaces, and a final wash down of the included surfaces. Water collection barriers were set up and collected water was filtered when necessary.

• DEP contractors completed work removing potentially hazardous dust and debris that accumulated on the roofs, windows and facades of downtown buildings following the WTC collapse. DEP contractors cleaned the surfaces of 221 building, or more than 3.6 million square feet of exterior building space, during the 10-month long project.

• DEP has inspected 1,073 buildings in and around Lower Manhattan. The following are the results of these inspections;

Buildings without debris on exterior surfaces 750 Buildings with exterior debris 323 Buildings cleaned by building owners and re-inspected by DEP 102 Buildings cleaned by DEP contractors 221

Unoccupied Building Clean Up Program

• DEP’s Unoccupied Building Clean Up Program was developed with funding from FEMA to clean up unoccupied buildings that still had WTC debris. Two buildings, 125 Cedar Street and 114 Liberty Street, were identified. DEP staff developed Scopes of Work for the clean up and air monitoring. The Scopes of Work were given to the building owners and the tenants.

• Several inspections with tenants and owners were conducted by DEP to hear the concerns of all involved and ultimately to explain the Scopes of Work with each tenant/owner concerning their individual apartments.
