The Sierra Club New York City Group objects strongly to the privatization
and expansion of the Westchester County Airport, and we urge you to do all
in your power to prevent it.

Expansion of the airport would put New York City drinking water at great
risk. Stormwater from the airport flows into the Kensico Reservoir, which
supplies 90% of the water in NYC and much of Westchester. Over 9 million
people get their drinking water from the reservoir, which is not filtered
before it is delivered to taps. Airport expansion would vastly increase the
likelihood of pollution of the reservoir, including both jet fuel and
deicing chemicals,  and privatization would decrease the accountability of
the airport.

This grave risk to the environment and to the health of New Yorkers must not
be allowed to go forward.
