Date Key Statement
10-25-01 NYCDEP described benchmarks and guidelines used to evaluate
environmental conditions in a letter to Lower Manhattan residents dated
October 25. In regard to cleaning indoor spaces the letter stated:
“If more than 1 percent asbestos was found and testing and cleaning was
necessary, it had to be performed by certified personnel.” In addition, the
statement indicated landlords should not reopen any building until a
competent professional had properly inspected their building. The City’s
Asbestos Abatement Program requires that building owners file a written
notification with the NYCDEP for asbestos abatement projects that do not
require plan or permit approval from the City’s Buildings Department.
NYCDEP officials told us this notification applied to buildings owners who
found more than 1 percent asbestos in bulk dust in their buildings (see
Appendix Q for a copy of the instructions).
NYCDEP officials told us they did not conduct a certification program, nor did they have
authority to conduct such a program, to determine the level of compliance with their instructions
regarding the testing and cleaning of asbestos inside buildings, unless a complaint was made or
an asbestos notification was filed with the City. Beginning in September 2001, they said they
began visually inspecting the exteriors of over 1,000 buildings and identified 323 buildings with
visible dust. NYCDEP documentation indicated that 101 of these 323 building exteriors were
subsequently cleaned by the building owners. NYCDEP officials told us that the remaining
owners stated they could not afford to clean their buildings, and these buildings were cleaned
by NYCDEP with funding provided by FEMA
To determine the extent of indoor contamination in Lower Manhattan residences, the
NYCDOH and ATSDR initiated an indoor air study in November 2001. The sampling phase
was completed in December 2001, preliminary results were released to the public in February
2002, and the final report was issued by ATSDR in September 2002.
EPA’s Initial Response
An EPA Situation Report for September 27-29, 2001, noted that a projected future action
was to “finalize sampling plan for residential buildings.” However, EPA’s Situation Report for
September 30 contained the following entry regarding indoor contamination:
Residential sampling/reoccupation: On 9/30/01, EPA spoke to
US Public Health Service and NYSDOH (New York State
Department ofHealth) who have been discussing issue with
NYCDOH NYC will not be requesting State or Federal assistance
