Interagency Agreement
Indoor Air Quality/Interior Cleaning of Residences
1. Purpose
The U. S. Environmental Protection Agency (EPA) will develop, manage and implement a
program to address the concerns of residents in Lower Manhattan regarding the impacts of the
World Trade Center (WTC) collapse on indoor air quality. This program will include the
offering of indoor sampling and interior cleaning of apartments in a specific area of Lower
Manhattan. EPA will provide oversight and management of cleanup and sampling contractors to
insure that activities are done as specified and to the satisfaction of the public. An extensive
Community Outreach Program will also be implemented. All requests and information obtained
during the implementation of this program will be managed through the development and
maintenance of a comprehensive database.
IL Authority
FEMA and EPA have entered into this Agreement pursuant to the Robert T. Stafford Disaster
Relief and Emergency Assistance Act (“Stafford Act”), 42 U.S.C. §§5121 et seq.; Executive
Order 12148, as amended, and 44 C.F.R. Part 206. The EPA shall provide oversight to cleaning
and sampling contractors to insure residences are satisfactorily cleaned to an acceptable standard.
III. Scope of Work
EPA, through close coordination with FEMA and state and city partners, will implement a
program to sample and clean residences in a specific area of Lower Manhattan. Those residential
spaces located south and/or west of Canal, Allen and Pike Streets will be eligible for cleaning
and sampling. It is estimated that up to 31,000 residences are located in this area.
Support for the cleaning and sampling of residences and the operation of a Hotline for residents
to request cleaning and sampling is being provided through contractors hired by New York City.
Contract language will enable EPA staff to manage and direct these contractors. EPA will also
be responsible for the management of all data generated during implementation of this program,
develop and maintain a website with frequent updates on its progress and implementation of an
extensive community outreach program which will be essential to the program’s success.
A risk assessment will be conducted using data generated from this program, the background
study and the residential cleaning study. Risk assessment is a key part of three interrelated
components of the indoor clean-up program. It will be used in the pilot cleaning program to
evaluate potential hazards associated with various cleaning methods. Risk assessment methods
are used to evaluate the pre-cleaning wipe samples as well as post cleaning air samples in the
main residential remediation program. It is also a critical part of the background study in that
clearance levels for apartments are a function of both risk-based and background levels.
