NYC 9/11 Public Portal Document r

Timing of the Longer Term Actions: Initial Actions have been initiated by agency staffs. Actions listed here could begin by June 1 and continue through February 2003.

1, Sampling to Determine Background Levels of Potential Contaminants

Program: EPA will sample residences in areas of NYC unaffected by WTC-related debris to establish what may be considered pre-existing levels of potential contaminants. It is likely that this sampling will occur north of 78'^ Street or whatever the appropriate designation is based upon improbability of any impacts from the WTC collapse and fire. This will assist EPA, ATSDR NYSDOH and NYCDOH in evaluating how the potential contaminants from the WTC disaster relate to pre-existing conditions.

Implementation: EPA will primarily conduct this project. NYCDOH will be responsible for assisting obtaining access to background locations a” j preparing notifications of results to residents. Monitoring will be done by contractors obtained through an OSWER contract. Analysis will be done by the same EPA - HQs contracts as the pilot cleaning effort. Seven potential indicators of concern have been identified, and air and debris/dust samples will be taken.

2. Creating a Data System with Existing Information Collected by NYC from the Private Sector on Environmental Testing Results and Clean Up Activity

Program: NYC has received information on clean up actions and air monitoring, possibly more, fi’om the building owners of a significant portion of the buildings in Lower Manhattan. Other information may also be available on building status. Making all such data available in an organized and readily accessible way will enhance ability to assess potential concerns related to indoor air environment.

Future Possible Action as Follow up to Above Action Plan

Identifying the Need for any further Potential Clean Up or Testing Support for Lower Manhattan

Objective: Be prepared to establish any necessary further Action Plan items for clean up or testing or infc.mation on clean up techniques which may emerge out of the various data collection, analysis and organizational efforts. Program : Unknown at this time. Must await results of above efforts.
