Definitions

Asbestos-Containing Material (ACM): The United States Environmental Protection Agency (EPA) has defined an ACM to be any substance containing greater than one percent asbestos by weight.

According to the EPA’s definition, friable asbestos is considered hazardous and refers to materials which can be crushed, pulverized, or reduced to powder by hand pressure when dry. Non-friable asbestos can be rendered friable by such actions as sanding, sawing, drilling, or breaking into pieces.

1.0 Purpose and Scope of Services

This report presents the results of the CONVERSE CONSULTANTS (CONVERSE) Asbestos Demolition Survey completed for the Holbrook Warehouse Facility located near Holbrook Junction in Douglas County, Nevada. The purpose of the survey was to identify accessible friable and non-friable asbestos-containing materials (ACMs) that may require abatement prior to the demolition of the structures.

2.0 Sampling Methodology

Prior to sampling, CONVERSE visually surveyed the interior and exterior of the structures for suspect asbestos-containing materials and homogeneous areas. Homogeneous areas refer to areas in which similar application, age, and appearance of building materials exist.

Our sampling methodology followed the general guidelines for bulk asbestos sampling as presented in Section 40, Part 763 (AHERA) of the Code of Federal Regulations (CFR) and extended to public buildings by ASHARA in 1994. Our visual survey was performed to classify each suspect building material by location and condition in order to establish homogeneous areas for bulk sample collection. Suspect materials were divided into friable and non-friable materials. Asbestos Containing Materials (ACM) were classified in one of the following EPA categories:

CONVERSE Project No. 15-23612-01 2

Category I (Non Friable) – gaskets, resilient floor covering, and asphalt roof products

Category II (Non Friable – non friable materials not listed as Category I Regulated asbestos containing material that is friable or could become friable during demolition

The site is developed with two structures. An approximate 1,200 square foot one–story, metal framed structure on a slab-on grade foundation, with taped/textured drywall walls and ceilings and flooring included 9” x 9” vinyl floor tile in the west room (the warehouse floor is concrete). The second building is a 36 square foot shed (originally a pump house). The structure is a one story building with taped/textured drywall walls and a gravel floor (there may be some concrete under the gravel). Both building exteriors are covered in transite panels, including the roof.

Following the visual portion of the survey, a total of 12 bulk samples were collected from areas representing the homogeneous use of suspect building materials. A summary of these samples is presented on the Survey Data Sheet in Appendix B.

In general, bulk samples were obtained by (1) adequately wetting the sample area with a water and surfactant mixture and (2) placing bulk pieces of the building materials into labeled plastic bags. Where possible, bulk samples were obtained to the depth of the affected area. Bulk samples were transferred to an analytical laboratory with continuous chain-of-custody documentation.

CONVERSE collected bulk samples consisting of the following suspect materials:

Wall Surfacing Joint Compound Drywall 9x9 Vinyl Floor Floor Tile Mastic Window Putty Transite Wall and Roof Panels

The laboratory analytical report, chain of custody documentation, sample location diagram, and photo page are provided in Appendix B of this report.

3.0 Discussion of Survey Results

The 12 bulk samples collected from the Property of suspect homogeneous materials were submitted to the CONVERSE asbestos lab located in Reno, Nevada for analysis by Polarized Light Microscopy (PLM). The asbestos samples were analyzed for asbestos

CONVERSE Project No. 15-23612-01 3 content by EPA Test Method 600/R-93/116. The CONVERSE asbestos lab is accredited by the U.S. Department of Commerce, National Institute of Standards and Technology (NIST), under the National Voluntary Laboratory Accreditation Program (NVLAP) for bulk asbestos analysis. For quality assurance purposes, ten percent (10%) of all samples received are subjected to duplicate, replicate or round-robin reanalysis. Per regulations, all layers of a sample must be analyzed as a separate material. A summary of the materials identified to be ACMs and the analytical results is presented in the following table.

4.0 Conclusions and Recommendations

Prior to the demolition activities, the following ACMs will need to be abated:

Table 1 – ACMs & Analytical Results

ACM Quantity Comments

Surfacing Joint Compound

≈ 4,000 s.f.

This material appeared to be typical to walls and ceilings in both structures. There are also pieces of the surfacing material on the gravel floor of the shed. This material will require removal during abatement activities.

9“ x 9” White with Gray, Vinyl Floor Tile and Mastic

≈ 210 s.f. This material appeared to be typical to west room in warehouse building.

Transite (Roof and Wall Panels) ≈ 2,900 s.f.

This material appeared to be on exterior walls and roofs.

Asbestos abatement must be performed by a State of Nevada licensed asbestos abatement contractor using 40-hour asbestos trained workers and appropriate wet methods and engineering controls. All asbestos abatement workers must have current asbestos training documentation, current medical exams and releases, and current fit tests for the use of personal protective equipment (PPE). The asbestos abatement contractor shall be responsible for estimating and verifying quantities of ACMs to be abated. The asbestos abatement contractor shall also be responsible for providing notification to EPA Region 9, Nevada OSHA and other pertinent governing agencies.

Transite water and sewer lines may be present at the property, which may be uncovered during the demolition process. This material may be disconnected at existing joints or snap cut by certified water department personnel if removal is required and disposed of as construction debris. However, if the material is crumbled, pulverized, or reduced to powder during demolition, the material becomes friable and would be covered by the asbestos “National Emission Standards for Hazardous Air Pollutants (NESHAPS)” regulations.

Friable materials such as the wall and ceiling surfacing must be disposed of as hazardous asbestos waste. Non-friable ACMs, such as the 9” x 9” vinyl floor tile and transite, may be disposed of as non-hazardous, asbestos-containing waste.

In addition, CONVERSE recommends that asbestos abatement activities be monitored by a NV-OSHA certified third party consultant that will document the asbestos abatement contractor’s use of 40-hour asbestos trained workers, engineering controls and work practices, perform visual inspections for the completeness of the abatement work, perform final air clearance testing for re-occupancy (if required) and monitor proper waste handling, transport and disposal of waste materials.
