Asbestos Survey, Fort Hood, Texas September 1997

1.0 INTRODUCTION

Radian International LLC, under contract with the United States Army Corps of Engineers

(USACE), Contract DACA56-94-D-0015, performed a facility-wide asbestos survey at Fort

Hood, Texas, to meet the following project objectives:

Identify and locate, to the extent possible, all friable and non-friable suspect asbestos-containing materials (SACM);

Evaluate the condition of the SACM, collecting sufficient data to perform a risk assessment and to prioritize materials for appropriate response actions;

Collect and analyze bulk material samples in order to quantify, in metric units, SACM which contain greater than 1% asbestos;

Identify and quantify material which is presumed to contain asbestos;

Conduct risk assessments for all asbestos-containing materials (ACM) and presumed

ACM (PACM);

Conduct air monitoring where necessary according to risk assessment models; and

Prepare an Operations and Maintenance (O&M) program (under separate cover) for all

ACM and PACM.

The survey included base buildings and approximately 10% of the family housing buildings at

Fort Hood. Mr. Emmet Gray, Directorate of Public Works, is the post contact for this project.

This report presents the findings from the asbestos survey at Building 29019.

1.1 Physical Inspections

Survey teams visually inspected the accessible areas of the interior and exterior of each building, including interior and exterior rooms, mechanical spaces, storage areas, crawl spaces, attics, and roofs, to identify appropriate homogeneous areas (i.e., unique SACM or PACM). A reasonable effort was made by the survey team to gain access to inaccessible areas. If access could not be gained, the survey team made assumptions regarding the presence and quantity of SACM based on the visual inspection of the remainder of the building and interviews with the building occupants.

The following steps were taken to complete physical inspections.

1. Obtain a copy of the building floor plan.

2. Perform an initial building walk-through.

a) Note fire doors/walls on the floor plan.

b) Identify homogeneous areas.

c) Identify locations of friable and non-friable SACM and PACM. PACM is defined as SACM which could be visually identified but which were inaccessible for sampling, or were not sampled at the client’s request.

d) Note the type, estimated quantity, description, friability, and physical damage of each SACM and PACM. Mark location(s) of SACM and PACM on the floor plan and take one color photograph of each homogeneous area to show materials and conditions present at the time of the survey.

e) Define the bulk sample locations.

1.2 Bulk Sampling and Analysis

Homogeneous materials were categorized by the survey teams as surfacing materials, thermal systems insulation (TSI), or miscellaneous materials. Building age, use, and size were taken into consideration, along with building materials, when determining sample locations. Three bulk samples were obtained from each SACM within each building surveyed. Homogeneous areas categorized as PACM were not sampled. Where applicable, bulk samples were collected from all material layers (e.g., roofing and flooring materials). Samples were collected by cutting, scraping, and/or coring. The following procedures were used during bulk sample collection:

1. Mark sample locations on the floor plan using a unique identification number.

2. Record SACM sample information on a field data sheet, including:

a) Building number and room number/area description;

b) Typical occupancy and population;

c) SACM description (e.g., pipe insulation, 9x9 brown floor tile, etc.);

d) Estimated quantity of SACM (i.e., area or length);

e) Friability;

f) Physical damage;

g) Potential for damage or disturbance during maintenance;

h) Potential cause of damage or disturbance; and

i) Unique sample identification number.

3. Take one color photograph from each homogeneous area to show materials and conditions present at the time of the survey.

4. Repair any damage caused by sampling using sealants and methods approved by the

Contracting Officer’s Representative (COR).

Samples were analyzed by RJ Lee Group, Inc. laboratory in Houston, Texas, using polarized light microscopy (PLM) coupled with dispersion staining (DS) in accordance with the Environmental

Protection Agency (EPA)-approved method USEPA 600/R-93/116: “Method for Determination of Asbestos in Bulk Building Samples.” In accordance with the Scope of Work dated 20 August

1996, point-counting was not performed. In order to meet quality assurance/quality control

(QA/QC) requirements, triplicate samples were collected from 5% of the sample locations for the overall project. Two of the samples, the normal and duplicate samples, were analyzed by the RJ

Lee Group laboratory. The third sample is the QA sample that was sent to the USACE

Southwestern Division Laboratory (SWD) in Dallas, Texas.

1.3 Sample Numbering Scheme

Unique identification numbers were assigned to each sample using the following numbering scheme:

aaaaa-b-c-xd, where:

aaaaa identifies the five-digit building number;

b identifies the subdivision within that building;

c identifies the homogeneous area;

x identifies the sample type, where:

0 = normal sample

8 = field duplicate (QC sample)

9 = QA sample d identifies the sample number (1,2, or 3)

[Note: “b-c” represents the unique homogeneous area identification (ID) for a particular building. When necessary, “e” is used by the laboratory to identify additional layers of material not separated in the field (e.g., tile and mastic associated with flooring materials.)]

2.0 FACILITY DESCRIPTION

Building 29019, encompassing an area of 31,698 sq ft, is an Enlisted Barracks (without dining area) built in 1975. A building floor plan is presented in Appendix B.

3.0 DISCUSSION OF RESULTS

Building 29019 was inspected during December 1996. During this inspection, 5 homogeneous areas were identified and 12 normal samples were collected. Table 3-1 presents a summary of

ACM and PACM identified during the survey of Building 29019. Appendix A contains a detailed table of homogeneous area descriptions for all SACM and PACM, and PLM analytical results for samples collected in Building 29019. Sample and photograph locations are presented in the Building 29019 floor plan (see Appendix B). Table B-1 contains information regarding inspector, risk assessor, and laboratory licenses for this building survey. Appendix C contains representative photographs of each ACM and PACM identified in Building 29019.

m2 = Square meter

Homogeneous areas 1-B and 1-D were identified as containing ACM or PACM. The risk assessment and abatement cost estimates for these materials are further discussed in Sections 4 and 5. All areas of this building were accessible to the field inspection team. Interior and incoming electrical wiring appeared to be non-ACM.

No field duplicate (QC) samples were collected from materials in this building.

4.0 RISK ASSESSMENT

A risk assessment was conducted for each homogeneous area containing ACM or PACM identified within the building using a modified version of the Air Force Guidance for Rating and

Assessing Damage and Exposure (GRADE) evaluation system. This system employs an algorithm that assists the risk assessor in assigning priorities to various situations identified during the inspection. The GRADE system divides the risk into two categories: damage/risk factors (D) and exposure factors (E). These factors are summed and placed in the following equation:

R = 12.0324 - [(0.1683 x D) + (0.1693 x E)].

Table 4-1 was used to establish a priority rating for each homogeneous area, based on the risk rating or “R” value.

Table 4-1

Priority Rating Table for Recommended Response Actions

Risk Rating (R) Priority Recommended Response Action

R < 6 1 Immediate removal/repair

6 R < 8 2 Planned removal/repair; place in O&M program in interim 1

8 R < 10 3 Place in O&M program

R 10 4 No action required; place in O&M program as a precaution 1 If material is repaired, it will remain in the O&M program until it is removed.

O&M = Operations and maintenance

R = Risk Rating

Risk assessments for the homogeneous areas identified as ACM or PACM in Building 29019 are provided in Table 4-2. Appendix D contains a summary of field observations used to determine damage/risk factors (D) and exposure factors (E). The methodology used to determine these factors is also provided in Appendix D. No air sampling was required in this building based on risk assessment models.

5.0 ABATEMENT COST ESTIMATES

Abatement cost estimates are based on professional experience and costs from 1996 Fort Hood asbestos abatement contracts. Cost estimates were developed using the unit costs for abatement of the general category of material and the estimated area of identified ACM determined during the survey. Unit rates for abatement include labor, materials, equipment, overhead, insurance, and profit. Abatement unit rates do not include costs for design, air sampling, materials replacement, or off-site disposal. Total costs do not include contract administration costs.

Cost estimates were developed using the assumption that all materials within a building would be abated concurrently. In addition, costs are based on the assumption that all ACM which is friable or which has the potential to become friable during demolition will require removal. Detailed cost estimates for abatement, replacement, and repair of ACM in Building 29019 are presented in

Tables 5-1 and 5-2.

RISK ASSESSMENT METHODOLOGY AND DATA FOR BUILDING 29019

Asbestos Survey, Fort Hood, Texas D-1 September 1997

Appendix D

Risk Assessment Data and Methodology identified within the building using a modified version of the Air Force Guideline for

Rating and Assessing Damage and Exposure (GRADE) evaluation system. This system employs an algorithm that assists the risk assessor in assigning priorities to various situations identified during the inspection. The GRADE system divides the risk into two categories: damage/risk factors (D), and exposure factors (E). These factors are summed and used in the following equation:

R = 12.0324 - [(0.1683 x D) + (0.1693 x E)];

Where D = the sum of the values for the following damage/risk observations:

Material type

Potential for contact

Physical damage

Water damage

Potential for damage by repair/maintenance activities

Asbestos content;

And E = the sum of the values for the following exposure observations:

Area of damaged material

Material friability

Population

Activity/vibration

Ventilation

Air movement

Floors

Walls

Barriers

A further breakdown of the values for the subunits under each category is provided in

Tables D-1 and D-2. Summaries of the inspection observations for damage/risk and exposure for the ACM and PACM in Building 29019 are presented in Tables D-3 and D-

2. Perform an initial building walk-through.

a) Note fire doors/walls on the floor plan.

b) Identify homogeneous areas.

c) Identify locations of friable and non-friable SACM and PACM. PACM is defined as SACM which could be visually identified but which were inaccessible for sampling, or were not sampled at the client’s request.

d) Note the type, estimated quantity, description, friability, and physical damage of each SACM and PACM. Mark location(s) of SACM and PACM on the floor plan and take one color photograph of each homogeneous area to show materials and consideration, along with building materials, when determining sample locations. Three bulk samples were obtained from each SACM within each building surveyed. Homogeneous areas categorized as PACM were not sampled. Where applicable, bulk samples were collected from all material layers (e.g., roofing and flooring materials). Samples were collected by cutting, scraping, and/or coring. The following procedures were used during bulk sample collection:

1. Mark sample locations on the floor plan using a unique identification number.

2. Record SACM sample information on a field data sheet, including:

a) Building number and room number/area description;

b) Typical occupancy and population;

c) SACM description (e.g., pipe insulation, 9x9 brown floor tile, etc.);

d) Estimated quantity of SACM (i.e., area or length);

e) Friability;

f) Physical damage;

g) Potential for damage or disturbance during maintenance;

h) Potential cause of damage or disturbance; and

i) Unique sample identification number.

3. Take one color photograph from each homogeneous area to show materials and conditions present at the time of the survey.

Samples were analyzed by RJ Lee Group, Inc. laboratory in Houston, Texas, using polarized light microscopy (PLM) coupled with dispersion staining (DS) in accordance with the Environmental Protection Agency (EPA)-approved method USEPA 600/R-93/116: “Method for

Determination of Asbestos in Bulk Building Samples.” In accordance with the Scope of Work dated 20 August 1996, point-counting was not performed. In order to meet quality assurance/quality control (QA/QC) requirements, triplicate samples were collected from 5% of the sample locations for the overall project. Two of the samples, the normal and duplicate samples, were analyzed by the RJ Lee Group laboratory. The third sample is the QA sample that was sent to the USACE Southwestern Division Laboratory (SWD) in Dallas, Texas.

Building 29020, encompassing an area of 42,264 sq ft, is an Enlisted Barracks (without Dining) built in 1975. A building floor plan is presented in Appendix B.

Building 29020 was inspected during January 1997. During this inspection, 5 homogeneous

ACM and PACM identified during the survey of Building 29020. Appendix A contains a detailed table of homogeneous area descriptions for all SACM and PACM, and PLM analytical results for samples collected in Building 29020. Sample and photograph locations are presented in the Building 29020 floor plan (see Appendix B). Table B-1 contains information regarding representative photographs of each ACM and PACM identified in Building 29020.

1-D Textured ceiling materials 3930 m2 None None ACM 1 A complete list of homogeneous areas and detailed analytical results are presented in Appendix A. Sample and photograph locations are shown on the building floor plan in Appendix B. Photographs are shown in Appendix C.

Homogeneous areas 1-A, 1-B, 1-C, and 1-D were identified as containing ACM or PACM. The risk assessment and abatement cost estimates for these materials are further discussed in Sections 4 and 5. All areas of this building were accessible to the inspection team. No interior or incoming electrical wiring was observed during the building inspection.

A field duplicate (QC) sample was collected at location 29020-1-C-01. The QC sample and normal sample yielded different asbestos results, but these are a result of different layers being found in each sample. The results of analysis for the QC sample indicated asbestos levels less than 1% (non-detect) in the brown paper and white plaster. The white plaster analyzed in the normal sample (29020-1-C-01) also did not have asbestos levels greater than 1 percent. Brown paper was not found in the normal sample, but brown paper was found in the sample collected at

29020-1-C-03. Analytical results for the brown paper in this sample also did not have asbestos levels greater than 1 percent.

The normal sample (29020-1-C-01) also had tan paint and white joint compound, which was not analyzed in the QC sample. The tan paint did not have asbestos levels greater than 1 percent, but the white joint compound had asbestos levels of 5 percent. These results are consistent with the analytical results for the other samples collected from this homogeneous area.
