October 25, ZOUt Dear Residents of Lower Manhattan;

Since September 11*, the U-S. Environmental Protection Agency (LPA), NYC Department of Environmental Protection (U£P), NYC Oeparfment of Health (DOH), wd the Occuputionsl Safety and Health Administration (OSHA), 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. The.se agencies consider the amount of time a person is exposed to a particular pollutant and where—a school, workplace or home—tn creating these criteria.

The following is a description of some of the benchmarks, standards and guidelines these agencies arc using to evaluate eavironxnental conditions m the aftermath of the World Trade Center disaster.

EPA is requiring the strictest protective standard under /LHERA, the .Asbestos Hazard Emergency Response Act, for asbestos in outdoor and indoor areas. (This standard is used to determine whether children may reenter s school building after asbestos has been removed or abated.) To be as protective as possible, EPA, together with NYCDE? and all the other health and environmenul 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 exterior areas with HEPA vacuums and wetwashing. NYCDEP and EPA have both conducted tuts in exterior spaces and all exterior areas of Lower Manhattan that were eluted passed their strict protective standards before being opened again tn the public.
