Attn. Arlene Anderson Re: Independence Plaza North (IPN) 310 Greenwich Street, Carpet Removal

Dear Ms. Anderson:

As you knov., in October 2001, II'N Management contracted with Commercial Lab Enterprises to conduct air tests for the presence of asbestos in our public corridors and to use the TEM protocol to analyze the samples. One floor, the 32nd floor corridor at the 310 Greenwich Street building, initially showed the presence of asbestos on 10.19.01. The area was HEPA vacuumed and the walls washed down. Subsequent re-testing and TEM analysis conducted on 10.24.01 revealed that there was no airborne asbestos in the corridor. Copies of the complete test results were sent to your Agency, the NYC Department of Health and the Independence Plaza North Tenant Association (IPNTA).

In August 2002, the IPNTA contracted with its own testing firm to conduct asbestos testing and analysis of the 32nd floor carpet. The results, which were sent to Commissioner Ward of your Agency on 12.15.02 (courtesy copy enclosed), indicated the presence of 1.3 million asbestos structures per square centimeter in the carpet (not airborne).

Although the DEP is completely responsible for the proper cleaning and testing of the building's common areas, Management is concerned about the huge discrepancy between our tests and analysis results (utilizing TEM technology), and the IPNTA tests/analysis, using the ultrasonification methodology.

Acccordingh-, Management respectfully requests that the DEP test and analyze the airborne particles in the 32nd floor hallway prior to removing the corridor carpet. If your tests indicate the presence of asbestos in excess of the permissible level, please confirm that the carpet will be removed in accordance with DEP's protocols for ACM.

V ry truly yours,

Deborah Dolan Manager
