ALC Environmental Incorporated (ALC) (License #00-0358) has been retained to
perform bulk sampling, visual assessments & air monitoring according to the EPA
Protocol to determine the presence of asbestos at the above referenced project.
Based on EPA Guidelines, we collected a bulk sample from this apartment and analyzed
it via Polarized Light Microscopy (PLM) Methodology. One (1) sample collected from
this apartment was found to be slightly above the regulatory limits of 1% by weight. (See

Approved Asbestos Abatement Inc. (License #99-1184), a certified asbestos abatement
contractor hired independently by the owner, was used to clean this specific apartment.
Upon completion of the asbestos clean up procedures, a visual inspection was conducted
in this specific apartment unit. No visible asbestos containing material (acm) or debris
was observed, ALC then performed final air clearance sampling.
The areas were cleared by ALC via Transmission Electron Microscopy (TEM)
Methodology. The results indicated that the work areas achieved the acceptance
criteria well below <70 structures per mm2 set by the above regulations.
The air sampling and analysis were done utilizing applicable Federal, State and City
Regulations pertaining to asbestos to include Federal OSHA (29 CFR 1926.58) EPA
