Dear Residents of Lawer Manhattan;
Since Scplember 11*. Inc U.S. Environmental Protection Agency (EPAJ. NYC Department of
fcnvironir.entai Protection (D£P), NYC Department of Health (DOIIJ, and the Occupational Safety
and Health Administration have been taking samples of the air, dust, water, river sediments
and drinking water and analyzing them for the presence of pollutants. The samples are evaluated
against a variety of benchmarks, standards and guidelines established to protect public health under
various conditions. These agencies consider the amount of time a person is exposed to a particular
pollutant and where—a schooE workplace or home—in creating these criteria.
The following is s description of some of the benchmarks, standards and guidelines these agencies
are using to evaluate environmental condicons m the-aftermath of the World Trade Center disaster
Asbestos in the Air / in Open Spaces
EPA is requiring the strictest protective standard under AJiERA, the .Asbestos Hazard Emergency
Response Act, for asbestos in outdoor and indoor areas. (This standard is used to determine whether
children may reenter a school building after asbestos has been removed or abated.) To be as
protective as possible, EPA, together with NYCDEP and all the other health and environmental
agencies, are requiring school reentry standards in tests around the World Trade Center site.
NYCDEP, USEPA, and NYC Department of Sanitation worked to perform cleanups of all dust in
estorior areas with HEPA vacuums and wetwashing. NYCDEP and EP.A have both conducted
tests in exterior spaces and all exterior areas of Lower Manhattan that were closed passed
their strict protective standards before being opened again to the public.
Asbexias tn liust in 3uilcJines
If a .suDslaiicc contains more than 1% asbc.stos, :l is uonsidercu to be an "asbestos-conlaining
inaterial." There are Federal, State, and City regulations in place to ensure the proper handling and
disposal of asbe.suih-viHiiaining material. If a substance ecmaiiis 1% or less asbestos, lhc.se
regullttions do not apply
