Q. Does the fact that you are doing a pilot cleaning project to assess cleaning methods
mean that you don’t think the advice given to apartment owners is sound?
EPA believes that the advice given to apartment owners is sound. In certain situations, where
apartments were not very dusty, wet mops and HEPA vacs are good ways to get rid of the dust
without allowing it to become airborne. For apartments with significant dust, EPA and
NYCDEP recommended professional cleaning, which would also mean methods designed to
prevent the dust from getting airborne. Because some residents have expressed concern about
the cleanup methods recommended by the city, EPA is doing this assessment to confirm the
effectiveness of the cleaning methods and, if necessary to make improvements or clarifications to
existing recommendations.
Q. What cleaning methods will you try?
A. We will clean using a variety of methods, ranging from wet mops and HEPA vacs to
professional level asbestos abatements. We will also test upholstery, furniture and carpets to see
what cleaning techniques work on these items.
Q. Why is EPA cleaning an unoccupied building, and not a building where people are
living and might be at risk?
A. EPA will chose a building that is unoccupied and has not been disturbed since September 11
because such a building will have the same conditions as many buildings did when they were
inititally cleaned. By using an undisturbed building, EPA can thoroughly test a number of
cleaning techniques and compare their effectiveness in a worst case scenarios.
Q. Have you chosen the building?
No. The city will provide EPA with a list of residential buildings that have not been cleaned or
re-occupied since Sept. 11. The list of options is likely to be very small. Access, structural
integrity, and proximity to the WTC site will be considered.
Q. When will you begin cleaning?
FEMA is working closely with the city to get the funding necessary to do the cleaning. Once the
funding is in place, EPA can begin the field work.
Q. How can I volunteer my apartment to be tested?
A. The New York City’s special hotline (212-221-8635) will take your requests.
