Dear Mr. Miller:

At the request of the Dormitory Authority State of New York, Professional Service Industries, Inc ('PSI) has been directed to performed periodic environmental testing at the subject facility. The first round of testing was performed on September 28 and September 29, 2001. Results of all air and surface testing for asbestos, lead, silica, and dust at that time were below the established regulatory or guideline levels for the selected analyte.

Due to accessibility issues PSI has been unable to return to the facility for subsequent testing uni December 15 and December 17, 2001. Frequent periodic testing will be performed on the site u •I further notice. PSI is working with $MCC facilities personnel to ensure Rill access to the site

Monitoring performed on 12/15 and 12117 includes testing for airborne asbestos, airborne silica, respirable dust, selected airborne mera's and Total Volatile Organic Compounds

Preliminary testing results follow.

Monitoring Asbestos in Air PSI collected 8 representative air samples from the Trailers at the West Side Highway location. In addition, I sample was collected from within the Gymnasium (north building) and Theater I (scutb building) as these areas were subject to use by emergency/rescue workers. Samples were collected and analyzed by Transmission Electron Microscopy in accordance with EPA 40 CFR Part 763 Final Rue (AI-RA) .JRA regulations establish the post abatement air clearance criteria for asbestos abatement projects performed within schools (Grades K-12). The AHERA post asbestos abatement clearance criteria is defined as an airborne asbestos fiber concentration less than 70 structures per millimeter squared (<70 s/rnm2). The samples collected are not intended to be post abatement clearance samples, and the results have been compared to the established AHERA criteria for the purposes of referencing an established regulatory Iimit.

Laboratory analysis found no asbestos fibers present in any of the samples collected. Refer to Table I for analytical results
