• Gentlemen:
ALC Environmental Incorporated (ALC) 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. Every apartment in the building
was assessed by our inspectors for dust and debris. Any area where visible dust and
debris was found. ALC's inspectors took a bulk sample, which was then sent to a third
party independent laboratory for analysis. In most cases there was insufficient debris to
sample and a visual assessment only was performed. Additionally, air sampling was
performed using TEM Methodology on every floor in the building.
Twelve (12) initial background air samples were collected and analyzed at building 400.
Twelve (12) samples were analyzed via phase contrast microscopy (PCM) and two (2)
were analyzed via Transmission Electron Microscopy (TEM). All were below the
permissible limits.
Based on EPA Guidelines, we collected one hundred fifty-eight (158) bulk samples and
analyzed them via Polarized Light Microscopy (PLM) Methodology. One (1) sample
collected from one apartment was found to be slightly above the regulatory limits of I %.
Zero (0) were found to be above the regulatory limits upon further analysis at a second
laboratory for quality control purposes. However, certified asbestos abatement
contractors hired independently by the owner, were used to clean the specific apartment
and the areas were cleared by ALC via TEM air sampling. All air samples were found
to be well below the permissible limits and the tenants where this cleaning took
place have been notified of the clearance.
ALC then collected air samples on every floor in the building. The air sampling and
analysis was done utilizing applicable Federal, State and City Regulations pertaining to
asbestos to include Federal OSHA (29 CFR 1926.58) EPA NESHAPS (40 CFR PART
61), AND TSCA TITLE 11 AHERA/ASHARA (40 CFR PART 763) Asbestos
Regulations; the New York State Department of Labor Industrial Code Rule 56 and the
New York City Department of Environmental Protection Title 15 Asbestos Regulations.
