wallboard at North of Nell Condominiums, Unit 3E, Aspen, Colorado.
Contractor: Prestige Environmental Services, Aurora, Colorado
Air Monitoring Description:
Phase Con provided final clearance air monitoring services at the project
site listed above on May 8, 2018. Air samples were situated inside the
enclosure so as to be representative of the entire work space. Air
samples were obtained utilized 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 ceiling texture by demolition of the ceiling wallboard.
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-occupiefl under non -abatement conditions.
