Dear Ms. Betah

assurance for the above referenced project. This service was conducted on December 3

Analysis of the air samples was performed using Phase Contrast Microscopy NIOSH

proficient for asbestos air test analysis. All final air tests were below 0.01 f/cc.
The asbestos containing materials were removed and the project was successfully
completed as per all applicable New York City, State, and Federal laws, rules, and
regulations.
