This report covers the results of testing performed on January 31th and February 1, 2002.
Monitoring performed on 1/31/02 and 02/01/02 included testing for Airborne Asbestos, Asbestos in Dust, Lead Surface Sampling, Airborne Silica, Respirable Dust, Total Dust and total Volatile Organic Compounds (VOC).
At the time samples were collected, Trailer windows were closed and }{EPA air filtration units were operating.
Based on the methodologies described in this report, this assessment revealed that, at the time of testing, measured parameters were within recommended guidelines.
Testing results follow.
Monitoring Asbestos in Air PSI collected 16 representative air samples from alternate floors from within the North and South Buildings and 8 representative air samples from each of eight of the Trailers on February 2 , 2001. Samples were collected and analyzed by Transmission Electron Microscopy in accordance with Environmental Protection Agency (EPA) 40 CFR Part 763 Final Rule - Asbestos Hazard Emergency Response Act (AHERA). AHERA regulations establish the post abatement air clearance criteria for asbestos abatement projects performed within schools (Grades K-12).

The samples collected are not intended to be post abatement clearance samples, and the results have
