August 3, 2005 Mr. Chris D'Alimonte New York City Department of Education Division of School Facilities 44-36 Vernon Boulevard Long Island City, NY 11101 Re: 90 & 100 Trinity Place (HS of Economics & Finance) Possible Air Infiltration from the Decontamination & Destruction of 133-135 Greenwich Street and 21-23 Thames Street Dear Mr. D'Alimonte: A thorough inspection of the subject structures and the adjacent structures has been conducted on July 6, 2005. Communicating openings, air intakes, and other potential pathways of contamination have been identified for inclusion in the decontamination design. Facility managers for the adjacent structures have been contacted so that engineering controls may be implemented to protect occupants. Of particular concern are air intakes of the school building directly to the east of the project site. These concerns have been addressed cooperatively with the Department of Education. The Copper Group's Asbestos Contractor will apply a hard barrier (plywood) over the existing 7"' floor fresh air intake louver on the West side of 100 Trinity, anchor it to the masonry, and then apply two layers of 6-mil polyethylene sheeting over the hard barrier. Since the fresh air intake louver will be covered, three (3) windows, in areas not occupied by students, on the 8`" floor (i.e. kitchen), will be opened to allow fresh air to penetrate the 8`" floor. The air from the opened windows on the 8`" floor will go thru a dropped ceiling which is the return air plenum for the 7`" floor MER with ducts that lead directly to the two (2) units. This will supply adequate make-up fresh air to the two units. The Copper Group's Mechanical Contractor will blank off the two fresh air intake ducts attached to the fresh air intake louver (approximately 12" x 6" each) on the 6`" floor (Exterior Fresh Air Louver on Thames Street is inaccessible) of 90 Trinity. It is the understanding that the HVAC unit in question is not in operation (has not been in operation for at least three years), and will not be put back into operation. Therefore, no make air is required. The Copper Group's Mechanical Contractor will also provide a temporary extension to the fresh air intake duct (100 Trinity) and extend it towards Cedar Street over the Auditorium Roof. If you have any questions or require further clarification, please do not hesitate to contact me. Sincerely, Airtek Environmental Corp. ~~ 2/4C Po'z `P.JL Michael Porter, Senior Project Manager Cc: Chanan Rozenbaum, The Copper Group 05-0701
