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 12011.

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 12011, encompassing an area of 6136 sq ft, is a Battalion Headquarters Building built in 1966. A building floor plan is presented in Appendix B.

3.0 DISCUSSION OF RESULTS

Building 12011 was inspected during November 1996, and was reinspected during March 1997 for additional mastic samples. During these inspections, 12 homogeneous areas were identified and 33 normal samples were collected. Table 3-1 presents a summary of ACM and PACM identified during the survey of Building 12011. Appendix A contains a detailed table of homogeneous area descriptions for all SACM and PACM, and PLM analytical results for samples collected in Building 12011. Sample and photograph locations are presented in the Building 12011 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 12011.

2 This homogenous area was inaccessible to the inspection team.

m2 = Square meter

Homogeneous areas 1-A, 1-B, 1-D, and 1-K 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. Homogeneous area 1-K was inaccessible to the inspection team. Interior and incoming electrical wiring appeared to be non-ACM.

A field duplicate (QC) sample was collected at location 12011-1-H-01. The results of analysis for the QC sample indicated asbestos levels less than 1% (non-detect). These results are consistent with the normal sample, which also indicated that asbestos was not measured above 1 percent.

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 12011 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 and/or PACM 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 and/or PACM 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 and/or PACM in Building 12011 are presented in Tables 5-1 and 5-2.

RISK ASSESSMENT METHODOLOGY AND DATA FOR BUILDING 12011

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

Appendix D Risk Assessment Methodology and Data

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 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 E : Lead-Based Paint Hazard Survey Building 12011-Interior & Exterior Painted Surfaces Fort Hood Army Base Fort Hood, Texas C E I Project Number: 9609

Clean Environments, Inc. conducted a lead-based paint survey on the interior surfaces of the referenced building, February 10, 2012. The survey was conducted by Mr. Ray Keeble, DSHS Certification JVs 206-0816 of Clean Environments, Inc., Lead Firm, DSHS Certification Ne 211-0096.

Lead samples were collected according to the sampling protocol stipulated in DSHS, Texas Environmental Lead Reduction Rules, and Department of Housing and Urban Development (HUD), Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing ("HUD Guidelines").

LEAD-BASED PAINT BACKGROUND

A lead-based paint hazard is a condition in which exposure to lead from lead-contaminated dust, lead-contaminated soil, or deteriorated lead-based paint would have an adverse effect on human health (as established by the U.S. Environmental Protection Agency (EPA) Administrator under Title IV of the Toxic Substances Control Act).

Lead-basedpaint is described as any paint, varnish, shellac, or other surface coating that contains lead equal to or greater than 1.0 milligram per centimeter squared (mg/cm2) as measured by XRF or laboratory analysis, or 0.5percent by weight [5,000 microgram per gram (pg/g), 5,000parts per million (ppm), or 5,000 milligram per kilogram (mg/kg)] as measured by laboratory analysis.

The common route of exposure to lead in paint is the ingestion of lead-bearing dust that is generated by the paint when it deteriorates, chalks, or is disturbed through demolition or renovation or even abrasion from the opening and closing of windows.

The severity of the health effects of lead contamination problems is only now being fully realized.

Lead in the body can cause serious damage to the central and peripheral nervous system, the cardiovascular system, and the kidneys. Children are especially vulnerable and susceptible to lead poisoning. Even low levels, persisting during childhood, are known to slow a child's normal development and cause learning and behavioral problems. The ASTDR and numerous other investigative agencies report long-lasting impacts on intelligence, motor control, hearing, and emotional development of children who have levels of lead in the body that are not associated with obvious symptoms.

Once in the body, from ingestion or inhalation, lead is distributed via the bloodstream to red blood cells, soft tissue, and bone. Lead in the body is eliminated very slowly by the kidneys and gastrointestinal tract; much smaller amounts are lost through perspiration. Lead serves no useful purpose in the body. It is a poison which binds with the chemicals that aid biological reactions throughout the body, particularly in the blood-forming system, the brain and nerves, and the kidneys, interfering with the synthesis of many body chemicals. The resulting damage from lead poisoning may be permanent, and in some cases fatal.

Chronic lead poisoning may result after lead has accumulated in the body over time, mostly in the bone. Long after exposure has ceased, some physiological event such as illness or pregnancy may release this stored lead form the bone and produce adverse health effects such as impaired hemoglobin synthesis, alteration in the central and peripheral nervous systems, hypertension, effects on the male and female reproduction systems, and damage to the developing fetus (lead freely crosses the placenta).

Exposure to lead is characterized either by the concentration of lead in the material (air water, food, dust, soil, or paint) to which people are exposed in the environment, or by the concentration of lead in whole blood, usually expressed in micrograms of lead per deciliter of blood (u.g/dl). The present level of concern for children is blood lead levels of 10 ug/dl. The Center for Disease Control (CDC) has a multi-tier prevention system to prevent this level of lead in children.

The Texas Department of Health, Texas Environmental Lead Reduction Rules, May 1998 does not require that the lead-based paint be abated from commercial or industrial buildings because such buildings are not considered target housing (pre-1978 with children 0 to 6 years old). However, 29 CFR 1926.62, Lead Exposure in Construction Final Rule (OSHA regulations), and the Texas Administrative Code (TAC) rules for waste classification and disposal, do apply. TAC 335.504, The Procedure for Hazardous Waste Determination, identifies lead waste in four classes — Hazardous, Class I , Class 2, and Class 3. This TAC section refers to 40 CFR 261 Subpart C defining "Characteristics of Hazardous Waste" and Subpart D listing hazardous wastes. TAC 335.505, .506, .507, define waste determination of Class 1, 2, 3 waste respectively.

The renovation/remodeling Contractor must be notified of the presence of lead-based paint in commercial or industrial buildings in order to adequately protect workers. Worker protection, to include medical surveillance and EPA training, is a Contractor, not Building Owner, responsibility.

The Building Owner, however, is responsible for waste stream determinations and disposal of the lead-based paint wastes. It is suggested that the lead-based painted substrates or scrapped paint chips be separated from other construction debris and a Toxicity Leaching Probability Characteristic (TCLP) laboratory procedure be performed on the lead-based paint waste to determine proper disposal.

Al l debris must be disposed in accordance with the requirements of 40 CFR 260,261,262,264,268.

Al l debris that is classified as hazardous, must be transported in accordance with 40 CFR 263. The Landfill must be registered/licensed with the State or EPA to accept lead hazardous wastes, as well as the transporters.

FINDINGS

The above referenced building is scheduled for renovation/demolition. Al l interior & exterior painted surfaces were tested for lead based paint (LBP).

The Innovx Spectrum Analyzer was used to collect XRF assays from components in the specified areas of the building. Positive results were noted at reading of 1.0 mg/cm2. Negative results were noted at readings of less than 1.0 mg/cm2. Inconclusive results were noted i f the numerical results that followed the greater than symbol were less than 1.0 mg/cm2. No inconclusive results were then resolved through K shell analysis.

The following areas tested positive for lead-based paint.
