L Introduction
On September 2" 2010, Mr. Mike Lococo of GeoStat conducted a final visual inspection and
final air clearance test at 816 Forrest Road, Vail, CO at the request of Mr. Alex Mintling of
Plumb Kendall Construction (PKC). Hudspeth removed Asbestos Containing Material (ACM)
from the spill on the first floor of the building. The final inspection and clearances of the work
area were performed in accordance with the applicable regulations upon completion of the
asbestos removal. The final inspection and clearances consisted of a final visual inspection of
the work area and the collection and analysis of final clearance air samples from within the work
area. Mr. Lococo is a Project Manager certified in the State of Colorado, and has an EPA
accreditation number 13438.
II. Final Visual Inspection
Upon completion of asbestos removal activities, a final visual inspection of the work area is
required by the applicable regulations. A certified AMS must visually inspect the work area for
any dust or debris remaining in the area. If any such dust or debris is noted by the inspector, the
abatement contractor is required to re -clean the work area until such time that the inspecting
AMS does not observe any dust or debris in the work area.
The final visual inspection of the site was conducted by Mr. Lococo on September 2 2010.
It was determined that the abatement contractor had properly cleaned the work area completely of
all dust and debris. No further cleaning was required by the inspecting AMS (see Appendix A).
III. Final Clearance Air Monitoring
Final clearance air samples must be collected from the work area after completion of a final
visual inspection and prior to tear -down of the containment structure. Analysis of each these
samples must show airborne asbestos fiber concentrations of less than or equal to 0.01 f /cc. If
concentrations exceed this limit, the abatement contractor must re -clean the work area and a
second set of final clearance air samples must be collected and analyzed. This process is repeated
until the analytical results of the final clearance air samples meet the regulatory standard. Only
upon successfully completion of the final clearance air monitoring process may an asbestos
abatement project be considered complete, and tear -down of the containment structure can
commence. The final clearance air sampling was completed by Mr. Lococo of GeoStat, a
certified AMS.
IV. Final Clearance Air Monitoring Sa nip] ing Methodology
Final air clearance samples were collected using constant flow high - volume air sampling pumps,
25 min air sampling cassettes, flexible tubing and adjustable sampling stands. The sampling
cassettes were attached to one end of the flexible tubing and placed on the stands approximately
forty-eight (48) inches above the floor. The opposite ends of the flexible tubing were attached
to the air sampling pumps. Each pump was activated and operated at a flow rate of
approximately ten liters per minute (10 LPM) for a period of approximately one hundred thirty
(120) minutes. Aggressive air sampling techniques as well as box fans, as described in 40 CFR
