NYC 9/11 Public Portal Document

1. INTRODUCTION:
The United States Environmental Protection Agency (USEPA) has been tasked to evaluate the
effectiveness of various cleaning procedures that may have been utilized in cleaning residential living
spaces located in the immediate vicinity of ground zero that are contaminated with dust and debris from
the World Trade Center (WTC) attack. The study will involve implementing various vacuuming and
cleaning techniques in separate apartments to determine their effectiveness. Comprehensive sampling
for Contaminants of Potential Concern (COPC) will be conducted throughout the study to determine
which method of cleaning is most effective at dust control. The building located at 110 Liberty Street
has been selected for the study. The location of the building in relation to ground zero is shown on
Figure 1.
1.1 BACKGROUND INFORMATION
The building at 110 Liberty Street is 5 stories with 12 residental and 6 commercial spaces and has been
unoccupied since 9/11. It is owned by David M. Baldwin Realty Co., Inc. The building is situated
between Liberty and Cedar Steets and has a co-address of 113-117 Cedar Street.
The collapse of the WTC severly impacted all spaces in the building with deposition of dust and debris.
Windows of residential and commercial spaces facing the WTC were blown out as were the sky lights
located in the ceilings of the three, 5”’ floor dwellings. The building was professionally cleaned shortly
after the collapse of the WTC. The cleanup was limited to all residential spaces, the basement and the
roof. None of the commercial spaces, except for unit 3A were cleaned. Two of the commercial spaces
(Unit 1 and Unit 2) are presently covered with inches of dust. All of the residential rental spaces
contain dust of various degrees due to redeposition of dust generated from the work effort at ground
zero.
The rental spaces range in size from 1,000 to 1,300 square feet. The residential spaces are of open
design and include a kitchen, bathroom and sleeping area. Commercial spaces identified as Unit 1, Unit
2 and Dwelling 3A were used as a Chiropractors office, a retail mattress showroom and offices of
Baldwin Realty, respectively. Each space is heated by an individual hot water base board system.
Window or roof mounted air conditioners are present in the residential space, central systems are
present in the commercial space (Unit 1 and Unit 2). Rental spaces are accessible from Liberty or
Cedar Streets through common hallways, floors are accessible via an elevator and stairs. The building is
presently without electricity and service is not expected to be restored until mid June. Each fioor has a
trash compactor room and a utility room. A laundry room is located on the 2"^ floor. The basement
contains the building trash compactor, elevator shaft, electric meter rooms, preparation and storage
areas for the Chinese restaurant, and a hair salon.
The study will be conducted on 12 residential and 3 commercial spaces. The two restaurants and hair
