Final Reports

IEA Project No. 0801196 Phase No.: 1 Response Start Date: April 2, 2008 Response Completion Date: April 2, 2008 Location: Room 209 Type of Containment: Critical Barrier Material Description

Material Type Asbestos Content Amount Response Action 9” x 9” Vinyl Floor Tile & Mastic Assumed 315 square feet Removal Response Stages I. Pre-Abatement Activities

Baseline cleaning was performed prior to construction of protective barriers. (This cleaning was conducted in compliance with Section 763.9 of AHERA.)

Critical barriers were used to lock out all ventilation systems, doors, windows, permanent fixtures and any other openings.

Polyethylene “splash guards” were constructed along all walls. A one (1)-stage decontamination unit was constructed contiguous to the work area. A one (1)-stage bag-out was constructed. Warning signs were posted at all access points.

II. Abatement Activities

The containment area was 2,889 cubic feet. Negative air pressure was established within the work area. This was accomplished with one (1) HEPA unit(s) rated at 2,000 cubic feet per minute. A visual inspection was made of the enclosure prior to removal to verify its integrity and evaluate the direction of

air flow. All applicable posting requirements were met. Entrance to and exit from the work area was observed to ensure that the appropriate personal protective

equipment was worn and decontamination procedures were followed. Visual monitoring of work practices was accomplished by observation from inside the enclosure during removal

and cleanup. The asbestos-containing material was saturated with amended water prior to removal from the substrate. All removal was completed in a nonfriable manner. The removed asbestos-containing material was immediately placed into appropriately labeled disposal bags

and/or drums before it was allowed to dry. All debris was cleaned up at the end of each shift. Periodic inspections were conducted for damage or penetration of the barriers in order to maintain the integrity of

the containment area. HEPA-filtered pressure differential unit(s) were inspected for proper functioning and cleanliness of pre-filters. Asbestos-containing mastic (adhesive) was removed using chemical solvents in a nonfriable manner.

III. Decontamination & Disposal

A final cleaning was conducted using HEPA-filtered vacuums and wet methods. All asbestos-containing material and contaminated debris was properly sealed in double 6-mil labeled bags or in

sealed drums. One (1) bag and three (3) barrels of containerized debris were decontaminated, removed from the enclosure and

stored in a locked storage area. A final inspection was conducted of the containment area on April 2, 2008, by Michael Altermatt. All surfaces were checked to ensure that no dust and/or debris remained. After final inspection, the floor surface was scrubbed with a one percent (1%) liquid Tide and water solution.

IV. Air Quality

A. Outside the Enclosure

No air sampling was conducted during the nonfriable removal of asbestos-containing materials (not required).

B. Clearance Sampling

No clearance air sampling was conducted after the nonfriable removal of asbestos-containing material (not

required). V. Project Closeout

After the non-friable removal was complete or clearance air was achieved, the temporary enclosure barriers were removed and disposed of as asbestos-contaminated debris.

All equipment and materials were removed from the area. An inspection was conducted of the area for damages and a punch list was compiled. The contractor is

responsible for addressing all punch list items prior to receiving final payment.
