NYC 9/11 Public Portal Document
Mr Rajappan Radhakrishnan — NYC DEP
133-135 Greenwich Street Variance Request
Airtek Project 05-0701— June 9, 2005
• Operable windows will be articulated, wet wiped, HEPA-vacuumed, and
encapsulated.
Following 2nd and 3rd cleanings and the settling periods, final air testing will be
conducted by TEM. Upon successful clearance air testing, the building will be
turned over to the demolition contractor for conventional demolition.
Phase III — Exterior In-Place ACM:
In-place ACM has been identified as follows:
1. Roof Flashing — 35 sf
2. Bulkhead Tar —10 sf
These materials will be abated last in the decontamination sequence. For detailed
information on the asbestos survey conducted, please refer to the Airtek Asbestos
Survey Report dated May 31, 2005 (Attached).
Structural Framing:
Due to the impossibility of removing structural framing without the risk of
building collapse, all structural framing will be wet-wiped, HEPA vacuumed, and
. encapsulated with penetrating encapsulant. As a part of the conventional
demolition that will follow the decontamination, these materials will be
characterized for asbestos content and RCRA characteristics, and will be disposed
of as appropriate based on the test results.
Thank you for your time and consideration,
Sincerely,
Michael Porter
