Regulatory Submittal Part I — Work Plan Fiterman Hall — 30 West Broadway, New York. New York Airtek Project 05-0867 — January 10, 2006

6.4 Operation IV - In Place ACM:

In-place ACM has been identified as follows:

Flooring materials Interior Facade Vapor Barrier Stair Bulkhead Window Caulk Spandrel Flashing

Per the requirements of the NYSDOL, these materials will be abated last in the decontamination sequence. As such, care will be taken to protect these materials from disturbance and/or damage during the gut-strip phase. ACM pipe insulation, if encountered, will be removed by NYS DOL Glovebag Procedures. For detailed information on the asbestos survey conducted, please refer to the Environmental Characterization Report, submitted under separate cover.

Flooring Materials:

Many areas of the Building have multiple layers of hard floor covering, including vinyl-asbestos floor tile. As all Remediation Phase gut-strip activities will be conducted in full-containment, for purposes of this project all hard floor covering materials will be treated as ACM and abated as a part of Operation IV - In-Place ACM.

Interior Facade Vapor Barrier:

The interior of the building facade, below the ribbon window system and behind the perimeter HVAC convector units, is coated with an ACM mastic vapor barrier. This material will be abated during the gut-strip operation of the Remediation Phase.

Stair Bulkhead Window Caulk:

Stair bulkheads at the roof level have older windows that contain ACM caulk. This material will be abated under a NYS DOL Variance at the commencement of the Deconstruction Phase.

Roof Membrane:

ACM roofing has been identified in one isolated location of the 14th floor setback roof. All other roofing and flashing materials have been confirmed non-ACM. This one section of roof will be abated as ACM at the commencement of the Deconstruction Phase.

Spandrel Flashing:
