Background

The DEP with assistance from representatives of the NYS DOL and US EPA performed follow-up site visits at buildings in the vicinity of the World Trade Center. The visual assessments disclosed the presence of various amounts of debris with various dispersal patterns at the building exteriors. The majority of buildings had isolated areas of debris specifically at the perimeter of the roofs, at the base of parapet walls, and in gutters. Debris was also visible at horizontal surfaces on some of the building facades. For some buildings, building facades facing the street were cleaned while the facades at the rear remained dirty.

The observed debris was characteristic of the debris from the impact of September 11, 2001. The debris appears to have reformed into a dense mass (caked). During the DEP follow-up visits, samples of the debris were collected from various roofs. The uneven dispersal identified above was also evident in the sample collection. Samples collected from various buildings indicated that some of the d'’bris was asbestos-containing material (ACM). Based on these results and the most stringent assessment and evaluation, this material is assumed to be ACM and shall be cleaned by NYS DOL licensed contractors with DEP and NYSDOL certified workers.
