NYC DEP Completes Downtown Cleanup
In October [DATE], the New York City Department of Environmental Protection (DEP)
officially wrapped up a five-month [CHECK] effort to remove potentially hazardous dust and
debris that had accumulated on the roofs, windows and facades of downtown buildings following
the World Trade Center (WTC) collapse. The project was both a feat of labor and logistics with
DEP crews working around the clock and making every accommodation possible to minimize
the disruption to area residents, businesses and institutions as they cleaned more than 1.8 million
[CONFIRM] square feet of exterior building space.
Beginning last winter [MONTH?], the DEP set about inspecting buildings in the area for exterior
residue containing more than 1 percent of asbestos, the threshold amount set by the U.S.
Environmental Protection Agency, the U.S. Department of Labor, New York State and the DEP.
In tests conducted on a small sample of downtown buildings in close proximity to the WTC site.
40 percent tested positive for asbestos contamination, prompting the DEP to commence a
comprehensive inspection of the more than one thousand buildings in the area.
“There was a great degree of anxiety among people in Lower Manhattan,” said Robert Avaltroni,
deputy commissioner of the DEP. “We felt that we needed to act quickly to relieve that anxiety
in order to help people who live and work in the area move forward with their lives.”
When the full inspection was complete, the DEP found the problem to be somewhat smaller than
preliminary tests had suggested. Of the 1.072 buildings the DEP inspected, 315 - less than 30
percent - tested positive for asbestos contamination and were earmarked for cleaning.
