Project: Ambient air monitoring inside a residential unit.
Client/Site Address: David Wilkins, 600 E. Main Street, Unit 309,
Aspen, Colorado
Air Monitoring Description
Phase Con provided ambient air monitoring services at the project site
listed above on November 15, 2018. Air samples were situated inside
the unit so as to be representative of the entire space. Air samples were
obtained and analyzed following the NIOSH 7400 Method, 'A' Rules for
PCM analysis. This method determines airborne fiber content which
meets the counting criteria for potential asbestos fibers and may include
asbestos fibers as well as any airborne particulate which meets the
counting criteria. This is the standard state regulatory method for
determining compliance with the Maximum Allowable Asbestos Level
(MAAL) in all public access spaces.
Comments and Recommendations:
PCM analysis of the ambient air samples inside the residential unit
revealed airborne fiber levels to be less than the Colorado State
Maximum Allowable Asbestos Level (MAAL) and the EPA clearance level
of 0.010 fibers per cubic centimeter of air; therefore, the area(s) may
be o�occupi�nder nop_7abatement conditions.
