Building 2735 Roof, Ft. Sam Houston, TX Environmental, Health, and Safety Consulting August 2015

ASBESTOS INSPECTION

Roof Only

Ft. Sam Houston, Texas

The on-site consultation was performed by Matthew Louderback, under the overall direction of Ronald M. Bishop, MPH, CIH. Matt Louderback is a Texas Department of State Health Services (TDSHS) licensed Asbestos Inspector (60- 2816) and Lead Risk Assessor (2070871). Ron Bishop is a TDSHS licensed Asbestos Consultant, Lead Project Designer, and Mold Consultant as well as a Certified Industrial Hygienist, Certified Safety Executive, Registered Sanitarian, Diplomate in Environmental Health, Registered Environmental Professional and Environmental Manager, Certified Environmental and Safety Compliance Officer, and Green Consultant.

1.0. GENERAL.

1.1. Construction materials containing asbestos have been used extensively in buildings because it possesses excellent properties for fire-proofing, insulation, and condensation control. Asbestos may be found in: (1) cement products; (2) spray applied or trowel applied materials on ceiling, walls, and other surfaces; (3) insulation on pipes, boilers, tanks, ducts, and other equipment; (4) vinyl floor tiles; (5) roofing; (6) flooring coatings; and (7) other miscellaneous products.

1.2. Friable materials are those materials that when dry can be crumbled, pulverized, or reduced to powder by hand pressure. Material that contains more than one percent asbestos by weight is considered to be asbestos containing material. Some of these asbestos-containing building materials are not considered friable now, but could become friable if not properly managed and maintained under an asbestos management program.

1.3. The concern about exposure to asbestos in buildings is based on evidence linking various respiratory diseases with occupational exposure in the shipbuilding, mining, milling, and fabricating industries. The presence of asbestos in a building does not mean that there is a significant health risk to building occupants. As long as asbestos-containing materials remain in good condition and are not disturbed, exposure is unlikely. Through proper control of building operations and maintenance activities, disturbance or damage to asbestos-containing materials is minimized, thus limiting the building occupant's exposure to airborne asbestos fibers.

1.4. Building alterations and/or demolition require knowledge of what materials contain asbestos and if they will be removed or disturbed during the project. Under the Clean Air Act, EPA has issued a National Emission Standard for Asbestos (40 CFR 61.140 - 61.156). This Standard regulates reporting requirements, work practices, waste disposal, and emissions from facility modification and/or demolition operations. The Standard applies only to materials containing more than one percent asbestos. The State of Texas has adopted a set of regulations (25 TAC 295.31 - 295.70) known as "Texas Asbestos Health Protection Rules" which govern asbestos removal, encapsulation, or enclosure, including licensing and regulation, in all buildings of public occupancy or access. Any disturbance or removal of ACBM in the building or facilities is subject to this Texas Statute.

2.0. BACKGROUND.

2.1. AEHS, Inc. was contacted by Ft. Sam Houston personnel, concerning the need for an Asbestos Inspection at Building 2735.

2.2. The initial request was from Mr. Greg Belnap for the roof only.

3.0. SCOPE OF WORK.

3.1. The inspection of building 2735 roof was performed on 12 August 2015 and consisted of visual assessments to determine the presence of suspect ACBM. Bulk samples of suspect ACBM (materials which possibly contain asbestos, as determined by an accredited EPA AHERA Building Inspector/ Consultant) were collected. The visual inspection, bulk sampling, and inspection documentation was performed by Matthew Louderback [Asbestos Inspector (No. 60-2816)].

3.2. AEHS, Inc. is a TDSHS Licensed Asbestos Consultant Agency (No.10-0335), PCM Laboratory (No. 30-0295), and an Asbestos Training Provider (No. 00-0068).

3.3. The specific objectives of the survey were to:

• Perform a visual inspection and physical assessment following the Asbestos

Hazard Emergency Response Act (AHERA) protocol as a guideline to identify, quantify, and assess accessible friable and non-friable ACBM;

• Collect and analyze bulk samples of suspect material for asbestos content and identification by an American Industrial Hygiene Association Accredited Laboratory that is also licensed by the Texas Department of State Health Services;

• Ensure the technical quality of all work by using the AHERA protocol and a TDSHS licensed consultant and inspector for the inspection; and

• Ιssue a final report that includes findings, bulk sample locations, and confirmed asbestos-containing building materials.

4.0. DESCRIPTION.

4.1. Building 2735 consists of multiple offices and retail facilities.

4.2. Renovation will include re-roofing.

5.0. INVESTIGATIVE METHODS.

5.1. Visual Inspection.

5.1.1. Building materials were inspected and assessed using the methods presented in the federal AHERA regulations (40 CFR, Part 763) as a guideline. The procedures mandated are considered the industry standard and are applied to all surveys performed by AEHS, Inc.

5.1.2. The suspect ACBM consisted of, Building 2735: roof penetration mastic, roof parapet mastic, and roof core.

5.2. Bulk Sampling.

5.2.1. Bulk samples of all homogeneous materials from identified functional spaces containing suspect ACBM were collected. A homogeneous material is defined as a surfacing material, thermal system insulation, or miscellaneous material that is uniform in use, color and texture. Examples of homogeneous materials include:

• Pipe insulation produced by the same manufacturer and installed during the same time period;

• Floor or ceiling tile of identical size, color and/or pattern;

• Sprayed-on acoustical ceiling materials located in contiguous areas; and

• Trowelled on plaster of same texture and location.

5.2.2. A functional space is defined as any spatially distinct unit within a building that contains identifiable populations of current or previous building occupants. Examples of functional spaces include:

• Office areas;

• Storage (warehousing) areas; and

• Living quarters.

The functional space concept is helpful in determining the use and occupancy of building areas containing confirmed ACBM. Knowing the types of occupants and their use of an area also may influence the selection of an asbestos management option and/or corrective action. If multiple corrective actions are necessary, the occupancy and use of individual areas may also become important factors when establishing the priority, or ranking, of each corrective action.

5.2.3. Prior to obtaining the samples, all friable suspect material are sprayed with amended (surfactant added) water to minimize fiber release. Small pieces of the suspect material were sampled by cutting off a sufficient quantity of the wetted suspect material in an inconspicuous location and securing the sample in a plastic bag. Samples were extracted from the center of the wetted area. The tool used to collect the suspect sample was then cleaned to ensure no cross-contamination occurred between samples. A plastic bag was used to contain the samples of the suspect material and quickly sealed to prevent the escape of the material or the introduction of ACBM contamination from outside sources.

5.3. Bulk Sample Analysis.

5.3.1. All bulk samples collected during this survey were analyzed by Environmental

Hazards Services, Inc.’s Laboratory in Richmond, Virginia. Environmental Hazards Services laboratory is accredited under the National Institute of Standards and Technology’s National Voluntary Laboratory Accreditation Program (NVLAP) and the American Industrial Hygiene Association. Additionally, the laboratory is a TDSHS licensed (No. 30-0188) Asbestos Laboratory (Polarized Light Microscopy). Their address, telephone number, and quality assurance review are depicted on their laboratory reports.

5.3.2. All asbestos samples were analyzed using Polarized Light Microscopy/Dispersion Staining (PLM/DS) techniques in accordance with methodology approved by the U.S.

Environmental Protection Agency (EPA), method number 600/R-93/116. The percentage of asbestos present in the samples was determined on the basis of a visual area estimation as set forth in 40 CFR Part 763, Appendix A, Subpart F, Section 1.2 and 1.7.2.4. The lower limit of reliable detection for asbestos using the PLM/DS method is approximately 1% by volume.

5.3.2.1. The Environmental Protection Agency considers materials with greater than one percent (>1%) asbestos content to be asbestos containing. Therefore, when asbestos containing building material (ACBM) appear in this report, it should be interpreted as meaning the sample(s) taken contained greater than (>1%) asbestos and is considered a regulated material. However, material that contains equal to or less than one percent is not considered to be asbestos containing material. If the results of sampling indicate that the asbestos containing material is a trace or up to 10% asbestos, the results must be verified by polarized light microscopy point counting or presumed to be asbestos. For this survey, AEHS personnel used their experience with similar materials.

5.3.2.2. When “No Asbestos Detected” (NAD) appears in this report, it should be interpreted as meaning no asbestos was observed in the sample material above the reliable limit of detection for the PLM/DS method.

5.3.2.3. The Texas Department of State Health Services requires a minimum of three samples to be collected from each homogeneous area. In order for a material to be considered negative, all samples must be negative. On the other hand, if one of the three samples is positive, then the material is considered positive.

6.0. RESULTS OF INSPECTION.

6.1. Analytical Results. The analytical results from the inspection and chain of custody are at Appendix A. A total of nine (9) samples were collected which resulted in eight (8) analyses due to layering and first positive stop.

6.2. Summary Positive Asbestos Containing Building Materials.

6.2.1. Roof Penetration Mastic – 2% Chrysotile Asbestos, approximately 100 square feet.

6.3. Photographs. Photographs are located at Appendix B

7.0. ASSESSMENT.

7.1. Friable Asbestos Material. None.

7.2. Non-Friable Materials. Roof penetration mastic.

8.0. RECOMMENDATIONS.

8.1. Maintain a copy of this report with the project files.

8.2. Abate the asbestos containing roofing material prior to re-roofing.

8.3. The abatement fall under NESHAPS; therefore, air monitoring nor specifications are required.

8.4. A TDSHS notification is not required because the quantity is below the NESHAPS threshold..

8.5. The contractor must follow the specific roofing requirements outlined in 29 CFR 1926.1101(g)(ii).

9.0. COST ESTIMATES.

Abatement – $1000.00

ASBESTOS AND LEAD INSPECTIONS

Fort Sam Houston, Texas

This report is divided into two sections corresponding to the consulting performed. The on-site consultations were performed by Matthew E. Bishop, CHSP and Ronald M. Bishop, MPH, CIH. Matt Bishop is a Texas Department of State Health Services (TDSHS) licensed Asbestos Inspector/Management Planner and Lead Risk Assessor. Ron Bishop is a TDSHS licensed Asbestos Consultant, Lead Project Designer, and Mold Consultant as well as a Certified Industrial Hygienist, Certified Safety Executive, Registered Sanitarian, Diplomate in Environmental Health, and Registered Environmental Professional, Registered Environmental Manager, Certified Environmental and Safety Compliance Officer, and Green Consultant.

A. ASBESTOS INSPECTION

1.1. Construction materials containing asbestos have been used extensively in buildings because it possesses excellent properties for fire-proofing, insulation, and condensation control. Asbestos may be found in: (1) cement products; (2) spray applied or trowel applied materials on ceiling, walls, and other surfaces; (3) insulation on pipes, boilers, tanks, ducts, and other equipment; (4) vinyl floor tiles; (5) roofing; (6) flooring coatings; and (7) other miscellaneous products.

1.2. Friable materials are those materials that when dry can be crumbled, pulverized, or reduced to powder by hand pressure. Material that contains more than one percent asbestos by weight is considered to be asbestos containing material. Some of these asbestos-containing building materials are not considered friable now, but could become friable if not properly managed and maintained under an asbestos management program.

1.3. The concern about exposure to asbestos in buildings is based on evidence linking various respiratory diseases with occupational exposure in the shipbuilding, mining, milling, and fabricating industries. The presence of asbestos in a building does not mean that there is a significant health risk to building occupants. As long as asbestos-containing materials remain in good condition and are not disturbed, exposure is unlikely. Through proper control of building operations and maintenance activities, disturbance or damage to asbestos-containing materials is minimized, thus limiting the building occupant's exposure to airborne asbestos fibers.

1.4. Building alterations and/or demolition require knowledge of what materials contain asbestos and if they will be removed or disturbed during the project. Under the Clean Air Act, EPA has issued a National Emission Standard for Asbestos (40 CFR 61.140 - 61.156). This Standard regulates reporting requirements, work practices, waste disposal, and emissions from facility modification and/or demolition operations. The Standard applies only to materials containing more than one percent asbestos. The State of Texas has adopted a set of regulations (25 TAC 295.31 - 295.70) known as "Texas Asbestos Health Protection Rules" which govern asbestos removal, encapsulation, or enclosure, including licensing and regulation, in all buildings of public occupancy or access. Any disturbance or removal of ACBM in the building or facilities are subject to this Texas Statute.

2.0. BACKGROUND.

2.1. AEHS, Inc. was contacted by Ms. Leslie Armstrong, 502nd Civil Engineering Squadron, concerning the need for Asbestos and Lead Inspections of the Exterior of Building 2735, Fort Sam Houston Texas, Texas.

2.2. The Point of Contact was Mr. Jonathon Scoggins, 502nd Civil Engineering Squadron.

2.3. The structure consisted of offices and restrooms for vendor operations.

3.0. SCOPE OF WORK.

3.1. The inspections were performed on 19 July 2013 and consisted of visual assessments to determine the presence of suspect ACBM. Bulk samples of suspect ACBM (materials which possibly contain asbestos, as determined by an accredited EPA AHERA Building Inspector/Consultant) were collected. The visual inspection, bulk sampling, and inspection documentation was performed by Matthew J. Louderback [Asbestos Inspector - (No. 60- 2816)].

3.2. AEHS, Inc. is a TDSHS Licensed Asbestos Constant Agency (No.10-0335), PCM Laboratory (No. 30-0295), and Training Provider (No. 00-0068).

3.3. The specific objectives of the survey were to:

• Perform a visual inspection and physical assessment following the Asbestos

Hazard Emergency Response Act (AHERA) protocol as a guideline to identify, quantify, and assess accessible friable and non-friable ACBM;

• Collect and analyze bulk samples of suspect material for asbestos content and identification by an American Industrial Hygiene Association Accredited Laboratory that is also licensed by the Texas Department of State Health Services;

• Ensure the technical quality of all work by using the AHERA protocol and a TDSHS licensed consultant and inspector for the inspection.

• Ιssue a final report that includes findings, bulk sample locations, and confirmed asbestos-containing building materials.

4.0. DESCRIPTION.

4.1. The inspection was of exterior surface only.

4.2. The exterior consisted of metal and stucco building materials.

5.0. INVESTIGATIVE METHODS.

5.1. Visual Inspection.

5.1.1. Building materials were inspected and assessed using the methods presented in the federal AHERA regulations (40 CFR, Part 763) as a guideline. The procedures mandated are considered the industry standard and are applied to all surveys performed by

5.1.2. The suspect ACBM consisted of stucco substrate.

5.2. Bulk Sampling.

5.2.1. Bulk samples of all homogeneous materials from identified functional spaces containing suspect ACBM were collected. A homogeneous material is defined as a surfacing material, thermal system insulation, or miscellaneous material that is uniform in use, color and texture. Examples of homogeneous materials include:

• Pipe insulation produced by the same manufacturer and installed during the same time period;

• Floor or ceiling tile of identical size, color and/or pattern;

• Sprayed-on acoustical ceiling materials located in contiguous areas; and

• Trowelled on plaster of same texture and location.

5.2.2. A functional space is defined as any spatially distinct unit within a building that contains identifiable populations of current or previous building occupants. Examples of functional spaces include:

• Office areas;

• Storage (warehousing) areas; and

• Living quarters.

The functional space concept is helpful in determining the use and occupancy of building areas containing confirmed ACBM. Knowing the types of occupants and their use of an area also may influence the selection of an asbestos management option and/or corrective action. If multiple corrective actions are necessary, the occupancy and use of individual areas may also become important factors when establishing the priority, or ranking, of each corrective action.

5.2.3. Prior to obtaining the samples, all friable suspect material are sprayed with amended (surfactant added) water to minimize fiber release. Small pieces of the suspect material were sampled by cutting off a sufficient quantity of the wetted suspect material in an inconspicuous location and securing the sample in a plastic bag. Samples were extracted from the center of the wetted area. The tool used to collect the suspect sample was then cleaned to ensure no cross-contamination occurred between samples. A plastic bag was used to contain the samples of the suspect material and quickly sealed to prevent the escape of the material or the introduction of ACBM contamination from outside sources.

5.3. Bulk Sample Analysis.

5.3.1. All bulk samples collected during this survey were analyzed by Environmental

Hazards Services, Inc.’s Laboratory in Richmond, Virginia. Environmental Hazards Services laboratory is accredited under the National Institute of Standards and Technology’s National Voluntary Laboratory Accreditation Program (NVLAP) and the American Industrial Hygiene Association. Additionally, the laboratory is a TDSHS licensed (No. 30-0188) Asbestos Laboratory (Polarized Light Microscopy). Their address, telephone number, and quality assurance review are depicted on their laboratory reports.

5.3.2. All asbestos samples were analyzed using Polarized Light Microscopy/Dispersion Staining (PLM/DS) techniques in accordance with methodology approved by the U.S.

Environmental Protection Agency (EPA), method number 600/R-93/116. The percentage of asbestos present in the samples was determined on the basis of a visual area estimation as set forth in 40 CFR Part 763, Appendix A, Subpart F, Section 1.2 and 1.7.2.4. The lower limit of reliable detection for asbestos using the PLM/DS method is approximately 1% by volume.

5.3.2.1. The Environmental Protection Agency and the Texas Department of State Health Services considers materials with greater than one percent (>1%) asbestos content to be asbestos containing. Therefore, when asbestos containing building material (ACBM) appear in this report, it should be interpreted as meaning the sample(s) taken contained greater than (>1%) asbestos and is considered a regulated material. However, material that contains equal to or less than one percent is not considered to be asbestos containing material. If the results of sampling indicate that the asbestos containing material is a trace or up to 10% asbestos, the results must be verified by polarized light microscopy point counting or presumed to be asbestos. For this survey, AEHS personnel used their experience with similar materials.

5.3.2.2. When “No Asbestos Detected” (NAD) appears in this report, it should be interpreted as meaning no asbestos was observed in the sample material above the reliable limit of detection for the PLM/DS method.

5.3.2.3. The Texas Department of State Health Services requires a minimum of three samples to be collected from each homogeneous area. In order for a material to be considered negative, all samples must be negative. On the other hand, if one of the three samples is positive, then the material is considered positive.

6.0. RESULTS OF INSPECTION.

6.1. Three (3) samples were collected which resulted in three (3) analyses. All results indicated 2% Chrysotile Asbestos with the actual laboratory results are at Appendix A. The three samples were point counted with the results being below the standard of greater than 1% of asbestos containing material; therefore, the exterior can be considered to NOT be asbestos containing material by EPA and the TDSHS – see paragraph 5.3.2.1., above.

6.2. Photographs are at Appendix B.

7.0. ASSESSMENT.

7.1. Friable Asbestos Material. None.

7.2. Non-Friable Materials. None.

8.0. RECOMMENDATION. Maintain a copy of this report with the project files.

B. LEAD BASE PAINT

1.1. Background.

1.1.1. Inspections and risk assessments for lead base paint (LBP) hazards emerged in response to an insurance problem in the nation’s public housing programs after children in housing units throughout the nation were found to contain elevated blood lead levels.

When investigations pursued, the houses were found to contain LBP where deterioration was extensive and the children were ingesting the paint directly (chewing on the sills, etc.)

or indirectly by placing contaminated items into their mouths.

1.1.2. At the present time, many of the standards used in lead hazard assessments are not health-based standards. A limit that will not produce adverse health affects has not been established for lead content of paint, dust or in soil. This is due in part to differences in individual behavior, particularly with respect to hand-to-mouth activity. However, the limits that are established in the various standards will significantly reduce the health impacts. Also, these limits dictate requirements for action, if exceeded.

1.1.3. The reason lead base paint inspections are conducted for commercial facilities is to determine potential worker exposure and environmental insult during demolition and disposal of the wastes based on the lead content.

1.2. Standards. As indicated in the Table 1 below, there are various standards that currently define lead base paint. The applicable standards to this project include the OSHA requirements, for worker protection performing the renovation, and the environmental requirements for disposal of materials painted with lead base paint.

1.3. Lead Risk Assessment.

1.3.1. A Lead Risk Assessment is to determine, and then report on the existence, nature, severity, and location of lead base paint hazards in residential dwellings through on-site investigations. Normally, risk assessments determine the immediately available sources of lead in a dwelling and provides advice on long-term and/or short-term responses to any hazards found. In general, inspections measure lead base paint concentrations while risk assessments measure lead base paint hazards.

1.3.2. The specific differences between an Inspection and a Risk Assessment depicted in Table 2, below.

Table 2 Inspections/Risk Assessments

Inspections Risk Assessments

Measure the concentration of lead in the paint on a surface-by-surface basis

Measure the level of lead in dust and soil and deteriorated paint

Identify the presence of lead base paint on all components

Identity the location and nature of all lead base paint hazards (primary prevention)

Allow the owner to avoid treating paint that is not lead base paint

Consider information about past maintenance and management practices

Allow the owner to treat all lead hazards present

Limited Risk Assessment/Inspection A combination of the Inspection and Risk Assessment tailored to the specific renovations to be performed under the specifications.

2.0. APPROACH.

2.1. Limited Inspection. A limited lead base paint inspection was conducted on 19 July 2013 at the location as described in paragraphs 2 and 4 of the Asbestos Section.

2.2. Credentials.

2.2.1. The Limited Inspection was performed by Matthew E. Bishop. Matt is a TDSHS certified Lead Risk Assessor (No. 2070727), which includes Lead Inspector.

2.2.2. AEHS, Inc. is a TDSHS certified/licensed Lead Firm (No. 21100283) and Lead Training Provider (No. 20439)

2.3. Methodology. XRF measurements were taken at representative locations on interior painted surfaces in the area of concern. XRF Niton Model XLp 300A (Serial No. 10381) was used in the testing for lead base paint. Calibrations were performed prior to and after testing each building in accordance with Performance Characteristics Sheets (PCS). See Appendix C for a table of the results.

3.0. RESULTS.

3.1. Seven (7) measurements were made with the XRF for lead content in paint.

3.2. Results.

Exterior. None.

4.0. DISCUSSION/CONCLUSIONS.

4.1. The HUD/EPA guidance for target housing is 1 mg/cm2 while the Toxic Characteristic Leaching Procedure (TCLP) limit for lead is 5 parts per million (ppm).

4.2. The OSHA requirements, as promulgated in 29 CFR 1926.62 (Lead Standard for the Construction Industry), considers any amount of lead as lead containing paint; however, any measured surface below 0.1 mg/cm2 should be considered negative for lead base paint.

4.3. Based on the measured results, it is highly unlikely that the debris will exceed the TCLP limit; therefore, a TCLP of the debris is not required.

5.0. RECOMMENDATIONS.

5.1. Maintain a copy of this report with the project files.

5.2. Provide a copy of this report to the contractor/owner and inform them that if the porch roofs are going to be disturbed, the contractor performing the work must adhere to 29 CFR

1926.62 – Lead Exposure in the Construction Industry.
