Contributions to Post-September 11* Recovery and Rebuilding
Exterior Building Clean-Up Program
• DEP performed inspections of exterior building surfaces, including the examination of roofs, facades, alleys,
fire escapes and ledges for the presence of visible debris from the collapse of the World Trade Center (WTC).
Buildings with visible accumulations of debris were identified, and building owners and managers were
directed to have the material tested and cleaned up appropriately. Follow-up inspections were performed based
on owner/manager written response.
• DEP’s Exterior Clean Up Program was developed with funding from the Federal Emergency Management
Agency 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. The projected completion date is 10/31/02.
• Building owners and 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. 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
4
exterior surfaces. The Help Center is at (718) DEP-HELP and operates 7 days a week, 24-hours a day.
• DEP has inspected 1,054 buildings in and around lower Manhattan. The following are the results of these
inspections;
Buildings without debris on exterior surfaces 747
Buildings with exterior debris 307
Buildings cleaned by building owners and
re-inspected by DEP, to date 70
License agreements received from building owners 152
Buildings cleaned by DEP contractors, to date 115
Support for EPA’s Residential Indoor Clean-Up Program
• DEP worked with the EPA to facilitate procurement for the EPA’s help line for Lower Manhattan residents to
request testing and cleaning of their apartments. The help line was opened on 6/3/02.
DEP has also worked with the EPA to develop scopes of work and procure contractors for the EPA’s indoor
clean-up program, which is scheduled to begin on 9/3/02.
Infrastructure Improvements and Repair
• DEP has worked closely with the Department of Design and Construction to investigate the condition of
existing sewers to recommend replacement, repair, or rehabilitation as necessary. DDC has performed the
work as per DEP requirements prior to the start of new utility or street work.
• DEP expanded the scope of work for a water main replacement project to include streets around and in the
vicinity of the WTC.
