Final Clearance Air Monitorinq Services
Date: April 19, 2017
Project: Abatement of ACM cement asbestos board panels from two
window panel work areas at The Meadows Reception Center, Aspen,
Colorado 81611.
Contractor: Prestige Environmental Services, Aurora, Colorado
Air Monitoring Description:
Phase Con provided final clearance air monitoring services at the project
site listed above on April 19, 2017. Air samples were situated inside the
enclosure so as to be representative of the entire work space. Air
samples were obtained utilizing aggressive sampling methods to aid in
ensuring that any fibrous material left in the enclosure would be
entrained in the air during the sampling period.
Abatement Description:
Abatement of ACM cement asbestos board panels from two window
panel work areas.
Comments and Recommendations:
PCM analysis of the final clearance air samples revealed airborne fiber
levels inside the containment area(s) 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 re;- ul)ied under non -abatement conditions.
