• In January/February of this year DEP, with assistance from EPA and State DOL, surveyed 452 building exteriors in the downtown area (Hudson River to Pearl Street and Chambers Street to Rector Place and Beaver Street). Approximately 211 buildings were identified as having varying amounts of debris on the exterior which was congealed and appeared to be residual debris from the WTC. • In addition, DEP sent specific information regarding the survey results to those 211 buildings identified as having debris on the exterior and requested that the owners assess the debris and conduct a cleanup based on the assessment. • In January/February, DEP sent letters to all 452 building owners in that area requesting information regarding assessments and cleanup procedures conducted by owners both indoor and outdoor. • Asa result of our mailing to the 452 buildings, DEP has received 269 responses from building owners, with the following results for asbestos in indoor spaces:

Please note, building owners have supplied data on other contaminants but DEP has not yet been able to collate them.

To date, DEP has verified 12 buildings in which an additional exterior cleanup was conducted. This is still ongoing. • In March, DEP sampled 44 of the exterior of buildings identified as having debris and found that 22 tested positive for asbestos.
