Subject: Asbestos Air Clearance Report
617 E. Cooper Avenue, Aspen, CO (Units 207 and 208)
To Whom It May Concern:
The following is the project completion report for the work areas located at 617 E. Cooper Avenue,
Aspen, CO (Units 207 and 208). The purpose of this report is to document this remediation project
was completed, and indoor asbestos amplification was not occurring in the work area.
The project remediation permit request was approved by CDPHE, the permit number had
not been received from CDPHE at the time of the clearance.
The remediation work areas (living area)were visually inspected in order to confirm the scope of
work was properly followed and completed. The containments were also visually inspected to
verify breaches and/or defects were not present.
An Industrial Hygienist for Earth Energy Environment (E3) performed the remediation project
completion inspection and testing procedures.
Phase Contrast Microscopy (PCM) samples were collected in accordance with the National
Institute for Occupational Safety and Health (NIOSH) method 7400 using cassettes (standard 3
piece, 25 mm dia., 0.8 urn MCE filter) purchased from Zefon International, Inc. Asbestos
concentrations in the containment were calculated as airborne fibers per cubic centimeter of air
(F/cc). Samples were read by an analysist working under Laboratory IHPAT Certification
No. 221103 (Proficient).

*BRL denotes "Below Reporting Limits". The PCM Colorado Department of Public Health and Environment
(CDPHE)clearance standard is 0.01 F/cc.
The PCM clearance air sample results were all below the CDPHE regulation 8 clearance standard
of 0.01 F/cc. Based on the information presented above, E3 concludes that the containment area
has passed the air clearance testing as of April 20th at 7:00 pm. The containment may be
removed, and the work area may be reoccupied after build back.
Thank you for allowing E3 the opportunity to provide environmental services to you. If you have
questions or require additional information, please contact me at (303) 902-5851.
