INTRODUCTION

Macrotec Consulting performed an inspection for Asbestos-Containing Building Materials and Lead Based Paint on July 8, 2011. The inspection was conducted for the project defined as: Demolition of building 433 at Nellis Air Force Base in Las Vegas, NV.

The intent of this inspection was to identify materials containing asbestos and lead based paint, within the subject site, that may be impacted during planned demolition activities. Macrotec’s inspection services were conducted at the request of Vince Bowers of the 99th Civil Engineering Squadron.

Dustin McAllister, a certified lead inspector, License No. NV-I-16781-1, and a Nevada Asbestos Abatement Consultant, License No.IM0961, and Jason McAllister, a Nevada Asbestos Abatement Consultant, License No. IM0901, conducted these services for Macrotec Consulting.

SCOPE OF SERVICES

Asbestos

Macrotec’s inspection services were conducted to identify the presence of any materials containing asbestos pursuant to the requirements of NAC 618.960 and in accordance with the inspection requirements of the EPA’s: 40 CFR Part 61 National Emission Standard for Hazardous Air Pollutants (NESHAP).

These regulations outline inspection and abatement requirements for materials containing asbestos, prior to renovation and/or demolition activities.

Lead

Macrotec collected paint chip samples to identify the presence and content level of lead for compliance with the Occupational Safety and Health Administration’s (OSHA) and the Environmental Protection Agencies (EPA) regulatory requirements pertaining to worker protection and waste disposal.

SITE DESCRIPTION

The subject site was the interior and exterior of a one-story building.

Macrotec’s inspection was limited to the location within the site planned for demolition as described above.

Nellis Air Force Base – Bldg. 433 Page 3

SAMPLE COLLECTION METHODOLOGY

An initial walk through of the subject site was conducted to identify homogeneous suspect materials containing asbestos and/or lead based paint, and their respective locations. This information was then used to develop a sample collection strategy.

Samples were collected by pre-wetting sample areas with water, then cutting or scraping the sample from the substrate with an appropriate sampling tool.

Whenever possible, samples were collected from areas previously damaged or deteriorating. To avoid potential contamination due to unknown asbestos and/or lead based paint content; no building systems, components, or structures were demolished to obtain samples of potentially hidden materials containing asbestos.

Each suspect bulk sample was sealed in its own zip lock plastic container and labeled with a unique identification number. Sampling tools were individually cleaned before and after each sample was collected to avoid sample cross contamination. Decontamination was accomplished using single use, pre-moistened cloths.

Samples were recorded on Macrotec’s chain-of-custody form. This form accompanied the samples to Triangle Enivronmental Service Center, Inc.

(TESC), located in Moseley, Virginia. The National Voluntary Laboratory Accreditation Program (NVLAP) accredits TESC for analysis of bulk building material samples for asbestos. The American Industrial Hygiene Association (AIHA) accredits Schneider Laboratories Inc. in Richmond Virginia, for analysis of paint chip samples for lead.

SAMPLE ANALYSIS METHODOLOGY

Asbestos

Suspect asbestos samples were subjected to analysis by polarized light microscopy (PLM). Bulk sample analysis was conducted in accordance with the EPA’s “Test Method for the Determination of Asbestos in Bulk Building Materials, EPA/600/R-93/116, 1993.

Lead

To determine lead content, the samples were submitted for analysis. Suspect paint chip samples were subjected to analysis in accordance with the EPA’s Method SW846-7420.

SAMPLE ASSESSMENT

Asbestos

Macrotec’s inspection of the subject site found Fifteen (15) separate suspect asbestos building materials, of which a total of Nineteen (19) samples were collected and submitted for analysis.

The following table summarizes the materials that were found to be asbestos containing, the locations where the material is located, the material’s friability and its NESHAP classification.

Material Number

Material Description

Material Locations

Material Friability

NESHAP

6 Gray Roof Penetration Mastic This material is on the penetrations on the roof.

Non- Friable

Category I

10 12x12 Floor Tile This material is located on the interior floor of the building.

Non- Friable

Category I1

11 & 15 Black Floor Mastic This material is beneath the floor tile and sheet flooring throughout the building

Non- Friable

Category II

See Appendix A for a listing of the materials, material locations, samples, sample locations and results for this project.

Lead

Macrotec collected Twenty One (21) paint samples of the predominate paint colors within the subject site.

Although none of the painted surfaces were found to be lead based paint (results above 5,000 parts per million), Nellis AFB may have further regulations for the handling of materials with paint over 600 parts per million. Those results are listed in the following table, which summarizes the locations of the painted surface and laboratory result.

Painted Surface Description

Material Locations

Lab Result (Parts / Million)

Brown Wood Fascia This material is located around the exterior perimeter of the building.

1,092

Brown Wood Soffit This material is located around the exterior perimeter of the building.

Brown Metal Flashing This material is located around the exterior perimeter of the building.

White/Green Ceramic Wall Tile This material is located in the restroom. 1,342

Category I nonfriable asbestos-containing material means asbestos containing packings, gaskets, resilient floor covering, and asphalt roofing products containing more than 1% asbestos as determined by Polarized Light Microscopy (PLM).

Category II non-friable asbestos-containing material means any material, excluding Category I, containing more than 1 percent asbestos.

RECOMMENDATIONS

Asbestos

No asbestos containing materials were identified in this investigation. If suspect materials are found during renovation activities outside what was identified in this report, stop work immediately until further testing can be completed.

Lead

None of the paints sampled in this investigation were found to be a lead based paint (above 5,000 parts per million). Please be advised that Nellis AFB may have further regulations for the handling of materials with paint over 600 parts per million. If suspect materials are found during renovation activities outside what was identified in this report, stop work immediately until further testing can be completed.

INSPECTION LIMITATIONS

The information contained in this report is limited to those areas and suspect materials found to be visually accessible through reasonable means.

Macrotec conducted a non-destructive survey. No demolition of building materials was conducted to determine the presence of asbestos in wall cavities, chases or other inaccessible areas. Macrotec cannot warrant that these areas do not contain asbestos in locations other than those noted in this report, however, a good faith effort was made to conduct a comprehensive survey.

• Macrotec accepts no liability for additional materials or under reporting of asbestos materials that exist below other floor coverings.

• This report is not represented as, nor is it intended to be, an asbestos abatement scope of work or project specification.

• If suspect materials are discovered during future demolition operations, cease all general work activities which could impact the discovered suspect materials, until confirmation sampling can be conducted.
