EXECUTIVE SUMMARY

This report summarizes the results of the suspect materials inspection performed by Tetra Tech, Inc.

(Tetra Tech) under Contract Number FA3002-07-D-0016, Task Order Number 3055. The property inspected is known as Building 820 which is located on Columbus Air Force Base (AFB), Mississippi.

Robert Carmody, a licensed Mississippi Asbestos Inspector, assisted by Ralph Everhart conducted the suspect materials inspection for the presence of asbestos on 18 January 2012. Mr. Carmody and Mr.

Everhart are United States Environmental Protection Agency (U.S. EPA) certified asbestos inspectors.

The Scope of Work consisted of performing a bulk sample collection of suspect materials and subsequent laboratory analysis for the presence of asbestos. Samples were analyzed utilizing the Dispersion Staining Method by Polarized-Light Microscopy. Samples with results two percent or below, based on the Dispersion Staining Method, were further analyzed using the Point Counting Method by Polarized-Light Microscopy at CA Labs, L.L.C., Baton Rouge, Louisiana.

The inspection was a mix of destructive and non-destructive sampling protocols as walls and ceilings were penetrated, floor surfacing components were sampled but not penetrated, and the roof was not disturbed. The investigation was conducted in accordance with the Occupational Safety and Health Administration and U.S. EPA guidelines for asbestos as well as other applicable federal and state regulations.

Laboratory results indicate the materials listed in Table ES-1 are asbestos-containing. Detailed descriptions of the asbestos results are presented in Table 3-1, Non-Friable Asbestos-Containing Materials, Table 3-2, Friable Asbestos-Containing Material, and Table 3-3, Non-Regulated Materials.

1.0 INTRODUCTION

This report documents the asbestos sampling conducted in Building 820 at Columbus Air Force Base (AFB), Mississippi. The sampling was conducted by Tetra Tech, Inc., (Tetra Tech) on 18 January 2012.

This report provides the sampling methodology, analytical results, and recommendations for managing asbestos at this facility.

Robert Carmody, a licensed Mississippi Asbestos Inspector, assisted by Ralph Everhart conducted the suspect materials inspection for the presence of asbestos on 18 January 2012. Mr. Carmody and Mr.

Everhart are United States Environmental Protection Agency (U.S. EPA) certified asbestos inspectors.

Copies of their certifications are provided in Appendix A. The Scope of Work consisted of performing a bulk sample collection of suspect materials and subsequent laboratory analysis for the presence of asbestos.

2.0 SAMPLING METHODOLOGY

This section describes the methodology used to conduct the survey. Information is provided on how sample locations were identified, how the hazard potential for asbestos-containing material (ACM) was classified, and the procedures used for sample collection and analysis.

2.1 IDENTIFYING SAMPLING LOCATIONS

Homogenous areas within the facility were identified during the visual inspection. Samples of suspect materials were collected for each homogenous area. A homogeneous area consists of an area of surfacing material, thermal system insulation (TSI) material, or other miscellaneous material that is uniform in color and texture1. A homogeneous area, as defined in this Survey Report, may occur in one or more locations within a building. The floor plan of the building is provided in Appendix B. The floor plan provides historical asbestos sampling data and results from this asbestos sampling event. Sampling locations, material types, and analytical results are depicted on the drawing.

2.2 DECISION TREE METHODOLOGY AND HAZARD RANKING

The process for classifying the hazard potential for ACM is displayed in the decision tree format shown in Appendix C, Asbestos Hazard Assessment Decision Tree and Hazard Ranking. The assessment method used considers the type, accessibility, and condition of the ACM. The assessment is based on the following factors: (1) the likelihood of increased disturbance due to accessibility; (2) the potential for future disturbance of previously damaged ACM; and (3) the probability that damaged ACM will release fibers when disturbed. Based on the condition and potential for disturbance of the material at the time of the inspection, the ACM is given an exposure hazard ranking from 1 to 7. Low numbers indicate a potentially high risk for exposure and thus a high abatement priority; high numbers represent relatively low asbestos exposure hazards.

2.3 SAMPLE COLLECTION, HANDLING, AND ANALYSIS

Bulk sampling of suspect ACM was conducted by personnel accredited under the Asbestos Hazard Emergency Response Act, the U.S. EPA Model Accreditation Program for Asbestos Building Inspectors.

Whenever possible, material for bulk samples was taken from inconspicuous locations. Practical

1 According to the Asbestos Hazard Emergency Response Act, Title 15 United States Code, Section 2651, 40 Code of Federal Regulations 763.

Page 2 Asbestos Analytical Data Report, Building 820 Columbus AFB, Mississippi precautions were used in collecting samples to ensure the safety of the survey personnel, nearby facility personnel, and occupants/users of the facility. Personal protective equipment such as half-face respirators with high-efficiency particulate air filters were worn as appropriate.

Specific procedures for conducting the sampling and analysis included the following:

Sampling was performed in a manner to ensure asbestos fibers were not released. This included wetting the surface of the suspect material to be sampled with surfactant amended water. Samples were collected by lifting off small pieces with a chisel, coring out a section, or cutting a piece off with a knife. All samples were placed in labeled, sealable canisters for delivery to the laboratory for analysis.

Tetra Tech personnel worked in conjunction with Columbus AFB personnel to collect data needed to complete on-going survey work. A combined minimum of three samples were collected per homogeneous area in accordance with Occupational Safety and Health Administration asbestos inspection requirements.

Samples were collected using carpenter knives and/or other sampling tools. The tools were thoroughly decontaminated after collecting each sample to prevent cross-contamination. Materials used for decontamination were bagged and disposed of properly. All bulk samples were carefully collected and inspected after collection to verify they contained all layers or substrates of suspect materials.

Bulk samples were individually placed in labeled, sealable canisters and delivered to CA Labs, L.L.C. (CA Labs), Baton Rouge, Louisiana.

Chain-of-custody forms were completed for all collected samples. Copies of chain-of-custody documents are provided in Appendix D.

The survey team repaired all suspect ACM disturbed for sampling purposes as appropriate. Very minor building maintenance activities, such as limited caulking, were required. To the extent practicable, inconspicuous locations were used as sampling sites since the building is occupied.

All bulk samples were analyzed by Polarized-Light Microscopy using the Dispersion Staining Method in accordance with the EPA Interim Method for the Determination of Asbestos in Bulk Insulation Samples, EPA 600/M4-82-020.

Samples with results two percent or below, based on the Dispersion Staining Method were further analyzed using the Point Counting Method by Polarized-Light Microscopy.

The percent asbestos is derived by calculating the percentage of asbestos points out of the 400 to 1000 fields counted.

Laboratory Accreditation. CA Labs met the accreditation and participation requirements specified in the Statement of Work for this project. All sample analysis was performed by CA Labs personnel. The laboratory is accredited under the National Voluntary Laboratory Accreditation Program (NVLAP) for bulk sample analysis for asbestos. Laboratory certifications are provided in Appendix E.

Chain-of-Custody Procedures. During the assessment, all bulk samples were recorded on the chain-of-custody form. Each sample was placed in a sealable container and labeled (with sample number and

Asbestos Analytical Data Report, Building 820 Page 3 Columbus AFB, Mississippi location) using a permanent marker. The inspectors inserted the samples collected each day in a re-sealable bag with the chain-of-custody form accompanying shipment to the laboratory. Survey team personnel were responsible for maintaining sample security and controlling sample integrity, except when the samples were in transit to the laboratory or in the custody of the laboratory. Prior to shipment, a copy of the chain-of-custody form was made for the project file. Copies of chain-of-custody forms are provided in Appendix D.

2.4 ASBESTOS LIMITING ASSUMPTIONS

In the event of future sample collection, all samples should be collected by an U.S. EPA certified asbestos building inspector and analyzed by an NVLAP accredited laboratory. If the condition of the material is such that it can be reduced to powder by hand pressure, the materials must be classified as friable.

3.0 RESULTS

Thirteen homogeneous areas were sampled and three samples were collected from each area. Asbestos-containing materials were detected in multiple homogeneous sampling areas in the inspected facility.

Positive analytical results are provided in Table 3-1, Non-Friable Asbestos-Containing Materials, and Table 3-2, Friable Asbestos-Containing Materials. Sampled materials that tested negative for asbestos are listed in Table 3-3, Non-Regulated Materials. Appendix B, Floor Plan, provides historical asbestos sampling data and results from this asbestos sampling event. Analytical results are provided in Appendix F, Asbestos Laboratory Analytical Data, and the data is summarized in this section. Photographs of the facility and sample areas are provided in Appendix G, Photographs of Facility.

3.1 POSITIVE ASBESTOS BULK SAMPLE RESULTS

4.0 CONCLUSIONS/RECOMMENDATIONS

The ACMs in Building 820 are in good condition and are not damaged. These materials may remain in the occupied facility as long as they are periodically monitored for friability and damage in accordance with the Columbus AFB Asbestos Management Plan. The plan should meet the requirements outlined in

Asbestos Analytical Data Report, Building 820 Page 5 Columbus AFB, Mississippi

U.S. EPA document 20T-2003, Managing Asbestos in Place: A Building Owner’s Guide to Operations and Maintenance Programs for Asbestos-Containing Materials.

4.1 MATERIALS ASSUMED POSITIVE FOR ASBESTOS

Tetra Tech recommends that prior to renovation, demolition, or disturbance of any kind, any materials that are assumed positive for asbestos and that will be impacted by the work should be sampled by a U.S.

EPA accredited asbestos inspector. The samples collected should be sent to an NVLAP and Texas accredited laboratory for analysis using generally accepted work and shipping practices. Until such a time that an actual determination of the composition can be made, it is lawful to treat the material as containing asbestos without laboratory analysis.

4.2 ASBESTOS-CONTAINING MATERIALS

The friable and non-friable materials found in the building are in good condition; thus, these materials may remain at the facility. Do note, however, that material now considered non-friable can, under certain instances, be rendered friable. The asbestos-containing materials should be periodically monitored for friability and damage and should be addressed in the Operations and Maintenance (O&M) Plan. The O&M Plan should address the proper management of the asbestos-containing material to include the following:

Training requirements;

Procedures for re-inspections;

Exposure assessments;

Notification requirements;

Labeling;

Record keeping;

Periodic ACM surveillance;

Repairing damaged material;

Delegation of a competent person to oversee the program;

Employee protection and medical surveillance programs;

Work practices for maintenance activities;

Specialized cleaning procedures; and

Emergency response procedures.

4.2.1 Facility Renovation

If renovation activities are planned, Tetra Tech recommends abatement activities be performed by a State of Mississippi Department of Environmental Quality licensed asbestos abatement company in accordance with all applicable federal, state, and local regulations. The abatement procedures should consist of the following:

Removal of ACM;

Notifying proper authorities;

Precautions against exposure;

Disposal of ACM waste;

Labeling;

Record keeping;

Third party oversight; and

Air monitoring.

Page 6 Asbestos Analytical Data Report, Building 820 Columbus AFB, Mississippi

4.2.2 Facility Demolition

Prior to demolition activities, the following actions are required:

Removal of all ACM that will potentially become friable during demolition activities;

Notification of contractors regarding the location of all ACM prior to any demolition activities;

Testing of any assumed ACM that may be potentially disturbed; and

Proper disposal of all ACM.

LDEQ

A "trace asbestos" will be reported if the analyst observes far less than 1% asbestos. CA Labs defines "trace asbestos" as a few fibers detected by the analyst in several preparations and will indicate as such under these circumstances.

Quantification of <1% will actually be reported as <=1% (allowable variance close to 1% is high). Such results are ideal for point counting, and the technique is mandatory for friable samples (NESHAP, Nov. 1990 and clarification letter 8 May 1991) under 1% percent asbestos and the "trace asbestos". In order to make all initial PLM reports issued from CA Labs NESHAP compliant, all <1% asbestos results (except floor tiles) will be point counted at no additional charge.

CA Labs is accredited by NVLAP for selected test methods for bulk asbestos fiber analysis (PLM) and airborne fiber analysis (TEM). All analysts have a college degree in a natural science (geology, biology, or environmental science) or are recognized by a state professional board in one these disciplines .Extensive in-house training programs are used to augment education background of the analyst. The group leader of polarized light has received supplemental McCrone Research training for asbestos identification. This report is not covered by the scope of AIHA accreditation.

Baton Rouge NVLAP Lab Code 200772-0 TEM/PLM TDH 30-0370

Summary of polarizing light microscopy (PLM / Stereomicroscopy bulk asbestos analysis) using the methods described in 40CFR Part 763 Appendix E to Subpart E (Interim and EPA 600 / R-93 / 116 (Improved). The sample is first viewed with the aid of stereomicroscopy. Numerous liquid slide preparations are created for analysis under the polarized microscope where identifications and quantifications are preformed. Calibrated liquid refractive oils are used as liquid mouting medium. These oils are used for identification (dispersion staining). A calibrated visual estimation is reported, should any asbestiform mineral be present. Other techniques such as acid washing are used in conjugation with refractive oils for detection of smaller quantities of asbestos. All asbestos percentages are based on calibrated visual estimation traceable to NIST standards for regulated of asbestos.

Traceability to measurement and calibration is achieved by using known amounts and types of asbestos from standards where analyst and laboratory accuracy are measured. As little as 0.001% asbestos can be detected in favorable samples, while detection in unfavorable samples may approach the detection limit of 0.50% (well above the laboratory definition of trace).

Vermiculite containing samples may have trace amounts of actinolite-tremolite, where not found be PLM should be analyzed using TEM methods and / or water separation techniques. Suspected actinolite/vermiculite presence will be indicated through the sample comment section of this report.

Fibrous talc containing samples may even contain a related asbestos fiber known as anthophyllite. Under certain conditions the same fiber may actually contain both talc and anthophyllite (a phenomenon called intergrowth). Again, TEM detection methods are recommended. CA Labs PLM report comments will denote suspected amounts of asbestiform anthophyllite with talc, where further analysis is recommended.

Some samples (floor tiles, surfacings, etc.) may contain fibers too small to be delectable by PLM analysis and should be analyzed by TEM bulk protocols.
