Department of Environmental Protection’s Exterior Clean-up Program
• DEP performed inspections of exterior building surfaces. The inspections included the examination
of roofs, facades, alleys, fire escapes and ledges for the presence of visible debris fi-om the collapse
of the World Trade Center (WTC).
• Buildings with visible accumulations of debris were identified.
• Building owners/managers were directed to have the material tested and cleaned up appropriately.
• Follow-up inspections were performed based on owner/manager written response.
• The Exterior Clean Up Program was developed (with funding from the Federal Emergency
Management Agency - FEMA) to clean up exterior surfaces that still had WTC debris.
• The Exterior Clean Up Program was initiated on 6/3/02, and is still in progress
• Building owners/managers whose properties were identified as having WTC debris were sent license
agreements to allow work to proceed.
• Three abatement contractors, chosen through the City’s procurement process, are cleaning exterior
building surfaces under DEP’s direction and oversight.
• A third party air-monitoring firm, also chosen through the City’s procurement process, performs air
sampling during clean-up activities.
• The clean-up work includes installing barriers, collecting all bulk debris, HEPA vacuuming and wet
wiping surfaces, and a final wash down of the included surfaces. Water collection barriers are set up
when necessary. Collected water is filtered.
• To date, the DEP has not received license agreements from all building owners/managers. Staff
continues to contact building owners regarding the program and return of the agreement.
The projected completion date of the Exterior Clean Up Program is 10/31/02.
• Orders to abate will be issued to building owners when necessary. Building owners refusing to take
advantage of the program will be mandated to pay for an appropriate clean up.
• The DEP Help Center continues to take information from individuals wishing to report visible debris
on exterior surfaces. The Help Center is at (718) DEP-HELP and operates 7 days a week, 24-hours a
day.
