Asbestos / Lead Survey Macrotec Project # 13580 Creech Air Force Base – Bldg. 95 Page 2

INTRODUCTION

Macrotec Consulting performed an inspection for Asbestos-Containing Building Materials and Lead Based Paint on June 27th 2013. The inspection was conducted for the project defined as: Demolition of building 95 at Creech Air Force Base in Indian Springs, 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 renovation 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. IMP0901, and a certified lead inspector, License No. NV-I-125427-1 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:

Nevada OSHA - NAC 618.960 OSHA’s “Criteria to rebut the designation of installed material as PACM

(Presumed Asbestos Containing Material)”, 1926.1101(k)(5).

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.

Lead

Macrotec collected X-Ray Fluorescence (XRF) readings to identify the presence and content level of lead above the action level (1.0 mg/cm2). The sampling for this project was collected in compliance with the U.S. Department of Housing and Urban Development (HUD) and the Environmental Protection Agencies (EPA) regulatory requirements.

SITE DESCRIPTION

The subject site is a one story concrete building that was once used for a electric vault but is now a office and storage building.

Creech Air Force Base – Bldg. 95 Page 3

Macrotec’s inspection was limited to this location only.

COLLECTION METHODOLOGY

Asbestos

An initial walk through of the subject site was conducted to identify homogeneous suspect materials containing asbestos and 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 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.

Asbestos 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.

Lead

Painted surfaces were then tested using an X-Ray Fluorescence (XRF) analyzer.

The XRF was a Niton XLp 300A paint analyzer serial #26948. The instrument was calibrated to the manufactures specifications before the inspection, every four hours, and after the inspection was finished, verified against the National Institute of Standards and Testing (NIST) Standard Reference Material (SRM) 2573 lead. The analyzer was in control at all times of the NIST SRM lead standard.

Interior and exterior XRF readings were taken on determined surfaces on each building component in each room equivalent. The HUD definition of lead based paint is lead equal to or greater than 1.0 mg/cm2. All results above this level are considered positive and all results found below this level are considered negative.

Creech Air Force Base – Bldg. 95 Page 4

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 painted surfaces were tested using an X-Ray Fluorescence (XRF) analyzer. The XRF was used in accordance with chapter seven of the Guidelines of the Evaluation and Control of Lead Based Paint Hazards in Housing published by HUD

SAMPLE ASSESSMENT

Asbestos

Macrotec’s inspection of the subject site found Eight (8) separate suspect asbestos building materials, of which a total of Ten (10) 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.

8 Transite Pipe This material is in the wire holes, protruding from the west wall in the

Front Room Bunker and presumed to be in various other locations below 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.

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

Creech Air Force Base – Bldg. 95 Page 5

Lead

Macrotec collected FiftySix (56) XRF paint readings within the subject site.

Some painted surfaces were found to be leaded (painted materials and/or surfaces above the HUD action level of 1.0 mg/cm2). OSHA regulations require the implementation of worker protection if there is a potential that paint with any amount of lead in it will be disturbed during demolition or renovation activities.

See Appendix B for a listing of materials that contain lead above the HUD action level and above the “Limit of Detection” (LOD). See Appendix D.1 for a listing of all the painted surfaces, XRF readings, and XRF reading locations and results for this project.

RECOMMENDATIONS

Asbestos

US EPA and Nevada Department of Industrial Relations regulations require the removal of all regulated asbestos-containing materials (RACM) prior to any renovation or demolition that could impact or disturb RACM. In accordance with these regulations Macrotec recommends:

Hiring a Certified Asbestos Consultant to develop a project specification based on this investigation and any other additional findings.

Hiring a Nevada licensed Asbestos Abatement Contractor to remove all asbestos materials, which are either regulated or may become regulated during the course of renovation and/or demolition activities.

Hiring a Certified Asbestos Consultant to monitor the removal activities and to provide final clearance inspection reports.

Macrotec recommends the removal of all ACM (in the manner described above) whenever feasible.

Lead

US EPA OSHA regulations require the implementation of worker protection if there is a potential that paint with lead in it will be disturbed during renovation activities. In accordance with these regulations Macrotec recommends:

Creech Air Force Base – Bldg. 95 Page 6

Hiring an EPA Licensed Lead Consultant to develop a project specification based on this investigation and any other additional findings.

Hiring an EPA Licensed Lead Abatement Contractor to stabilize and/or remove all regulated lead painted materials.

Hiring an EPA Licensed Lead Consultant to monitor the removal activities and provide final clearance inspection reports.

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.
