the dust and debris emanating from the collapse and the ensuing fires created
environmental concerns for the public that have persisted more than a year after
the disaster.
Airborne dust from the collapse of the towers blanketed Lower Manhattan and
was blown or dispersed into many of the surrounding office buildings, schools,
and residences. One person described the aftermath in Lower Manhattan as
“looking like a blizzard” had hit. However, this blizzard did not deposit snow,
but instead a complex mixture of building debris and combustion by-products.
This mixture included, among other substances, asbestos, lead, glass fibers, and
concrete dust.
In addition to the initial dispersion of
dust and debris, fires at the site
created various emissions of
potentially harmful pollutants. These
fires were not officially declared
extinguished until December 19,
2001, and debris continued to
smolder and fires flared up for weeks
after that. Emissions resulting from
these fires included particulate
matter, various metals,
polychlorinated biphenyls (PCBs),
volatile organic compounds (VOCs),
polycyclic aromatic hydrocarbons
(PAHs), and dioxin.

President signed a major disaster
declaration for the five counties of
New York City to provide assistance
to New York State, thus activating
the Federal Response Plan (FRP).
The FRP establishes the process and
structure for the Federal Government
to provide assistance to local
agencies when responding to the
consequences of any major disaster
or emergency declared under the
Robert T. Stafford Disaster Relief
and Emergency Assistance Act, as
amended (42 U.S.C. § 5121, et seq.).
