EXECUTIVE SUMMARY

In July 2019, Myounghee Noh & Associates, L.L.C. (MNA), was retained by Jacobs, to conduct a targeted hazardous material survey at Building 51109 located on Andersen Air Force Base, Guam. Targeted were those areas anticipated to be disturbed during the planned construction of an addition to the existing Missile Assembly Shop (Building 51109).

The objective of the survey was to identify the presence, extent, and conditions of hazardous materials in and on the building in the areas anticipated to be disturbed, so that the information can be incorporated in the design.

On 14 May 2020, MNA, with field support from Unitek Environmental Guam, conducted this hazardous material survey and identified 14 suspect building materials. Based on sampling and analysis of 30 asbestos/bulk and eight lead/paint chip samples, MNA provides the following summary:

One asbestos-containing material (ACM), off-white sealant on concrete wall.

No lead-containing paint (LCP) were found in the project area.

No suspected arsenic-containing material were observed in the project area.

Based on the visual survey and sampling and analysis of suspect bulk materials and paints, special hazard control measures are warranted for work involving asbestos. These control measures are briefly described in Section 8 Recommendations for Renovation and Construction Work. General dust and runoff controls and environmental protection are also warranted.

Contractors must verify, prior to bidding, the location and volumes of potentially hazardous materials and determine the appropriate dust and hazard control measures based on the area and material to be disturbed. Quantities of materials provided in this report are based on visual approximations only during the survey and should not be used for bidding purposes.

Analytical results provided in this report do not meet the requirements for waste characterizations.

Contractor must coordinate with permitted landfills for required waste characterizations.

Any ACM disturbance exceeding 3 square feet or 3 linear feet of friable ACM or generating 0.5 cubic feet of ACM debris is considered a regulated activity. Contractors are required to comply with 29 CFR 1926.1101(k)(3)(i) to identify the presence, location, and quantity of ACM before any work is begun.

1.0 INTRODUCTION

Myounghee Noh & Associates, L.L.C. (MNA), under an agreement with Jacobs Government Services Company, conducted a targeted hazardous material survey for the MCAF P- 3001/AJJY203001, APSI-Standoff Weapons Complex, MSA 2, Building 51109, located on Andersen Air Force Base, Guam. Unitek Environmental Guam was a subcontractor to MNA to support the field survey due to the 2020 COVID-19 pandemic travel restrictions. The survey was conducted in support of the planned building modification project. Targeted were those areas anticipated to be disturbed by the renovation and construction work, including hazardous building materials due to the suspected presence of asbestos, lead, or arsenic (Table 1):

Table 1. Anticipated Design Scope of Work Room Work Anticipated Building 51109

Construction of an addition to the building, including access and transportation pavements, grading and drainage improvements, and supporting utility infrastructure.

2.0 SAMPLING AND SURVEY METHODS

On 14 May 2020, a State of Arizona-certified building inspector, Brad Wolfe of Unitek Environmental Guam conducted the hazardous material survey on behalf of MNA. The inspector performed a visual assessment of the project site, identified materials suspected of containing asbestos, lead, or arsenic, and collected samples of these materials. Inspector certifications are presented in Appendix A.

2.1 Identifying Homogeneous Materials

The inspector identified building materials with the same appearance, color, and substrate as homogeneous materials. Interior homogeneous materials are considered unique per building and building floor, while exterior building materials are considered unique per structure. Building materials with the same characteristics (appearance, color, and substrate), as an identified homogeneous material, should be considered to possess the same hazard characteristics, unless specifically identified as otherwise in the report. As an example, if cream paint on concrete is found to be lead-based paint (LCP), then all identical cream paint on concrete in the survey area should be treated as LCP. Table 2 provides an overview of sampling and a summary of hazardous materials identified.

2.2 Building Material Sampling

Bulk and paint samples were collected using a decontaminated chisel, razor, or hammer in a manner that minimized airborne dust. The inspector collected triplicate samples for asbestos and duplicate samples for lead. No suspected arsenic-containing building materials were identified.

Samples were placed in sealable plastic bags, labeled with a unique identification number, and recorded on a chain-of-custody. For each sample, the date, sample appearance, analyte, and sample location were recorded on a field data form. All samples were transported under chain-of-custody to Hawaii Analytical Laboratory in Honolulu, Hawaii.

3.0 LABORATORY INFORMATION

Hawaii Analytical Laboratory analyzed the asbestos samples by polarized light microscopy using the Environmental Protection Agency (EPA) Method 600/R-93/116 and the lead samples by flame atomic absorption spectroscopy using the EPA Method 7082m. Hawaii Analytical Laboratory, Honolulu, is certified by:

National Voluntary Laboratory Accreditation Program (NVLAP), certification 200655-0 State of Hawaii Department of Health (HDOH), certification L-14-002 American Industrial Hygienist Association (AIHA) Environmental Lead Laboratory

Accreditation Program (ELLAP), certification 101812

4.0 ASBESTOS RESULTS

Materials determined to contain greater than, or equal to, 1% asbestos are considered regulated asbestos-containing material (ACM) under the National Emission Standards for Hazardous Air Pollutants (NESHAP) as specified in 40 Code of Federal Regulations (CFR) Part 61 Subpart M.

The U.S. Occupational Safety and Health Administration (OSHA) Asbestos General Industry and Construction Standards also define ACM as 1% asbestos or more by volume under 29 CFR

1910.1001 and 29 CFR 1926.1101, respectively. However, any measurable levels of asbestos fibers are considered to be a health concern, in an uncontrolled work environment.

2735_1 4 Myounghee Noh & Associates, L.L.C.

Ten homogeneous materials suspected of containing asbestos were identified and sampled, generating 30 samples for analysis. One ACM, off-white sealant on concrete, was confirmed in the survey area, with a result of 2% chrysotile asbestos (Table 3).

The suspected ACM descriptions and identifiers are provided in Appendix B. Sample and hazardous material location drawings are provided in Appendix C. Photographs of suspected materials are presented in Appendix D. Laboratory analytical reports, chain-of-custody, and field data forms are provided in Appendix E.

5.0 LEAD RESULTS

The U.S. Department of Housing and Urban Development (HUD) and the EPA define paint containing 5,000 milligrams per kilogram (mg/kg), or 0.5% by weight, or more of lead to be lead-based paint (LBP). Paint containing any measurable concentration of lead is considered to be LCP and a health concern. When lead is detected in a multi-layer sample, it is assumed that all layers represented by the sample contain lead at the same concentration.

2735_1 5 Myounghee Noh & Associates, L.L.C.

Four suspected lead paints were identified and sampled, generating eight paint chip samples.

Laboratory analytical results indicated no measurable levels of lead. Therefore, it is concluded that no lead paints are present in the project area.

Suspected LCP descriptions and identifiers are provided in Appendix B. Sample location drawings are in Appendix C. Photographs of suspected LCP are presented in Appendix D. Laboratory analytical reports, chain-of-custody, and field data forms are provided in Appendix E.

6.0 ARSENIC RESULTS

The disturbance of arsenic-containing materials is regulated by the OSHA Inorganic Arsenic General Industry Standard under 29 CFR 1910.1018.

No suspected arsenic-containing materials were observed; therefore, no samples were collected during this survey.

7.0 SUMMARY OF SURVEY RESULTS

A targeted hazardous material survey was conducted at Building 51109, on Andersen Air Force Base, Guam. The survey was conducted in support of the planned building modification project (design scope in Table 1).

Based on the analysis of 30 asbestos-suspected samples and eight lead-suspected samples, MNA provides the following summary:

8.0 RECOMMENDATIONS FOR RENOVATION AND CONSTRUCTION WORK

It is required that properly trained employees perform demolition and construction work that disturbs hazardous materials, in a manner protective of the site workers, facility users, and the environment. The following recommendations address OSHA and other applicable federal requirements. These recommendations provide guidance for the management of hazardous building materials and control of occupational and environmental hazards associated with operations, maintenance, renovation, and demolition. These recommendations are based on

2735_1 6 Myounghee Noh & Associates, L.L.C.

information gathered during the hazardous materials survey. These recommendations are not intended to constitute a formal work plan but are intended to provide a starting point for the development of a work plan.

8.1 Asbestos-Containing Materials

Employees involved in demolition and construction activities that disturb asbestos must conduct work in accordance with 29 CFR 1926.1101, the OSHA Asbestos Construction Standard. Work practices that would trigger these requirements include, but are not limited to, repair, maintenance, or renovation of structures containing asbestos, as well as removal or encapsulation of materials containing asbestos. For each project, the contractor must determine the appropriate safety measures based on the area to be disturbed, the type, volume, and condition of asbestos materials.

Applicable work practice guidelines involving the disturbance of asbestos materials are summarized, but are not limited to:

Employees must anticipate hazards and utilize appropriate engineering controls and personal protective equipment (PPE).

Employers must provide and require the use of appropriate PPE for any employee exposed to airborne concentrations of asbestos that exceed OSHA regulatory limits, or for which a required negative exposure assessment is not produced (29 CFR 1926.1101[i][1]).

Employees must utilize respiratory protection until the initial exposure monitoring assessment documents safe working levels of airborne asbestos (29 CFR 1926.1101[f] and [h]). Additional periodic exposure monitoring may be required.

An initial exposure monitoring assessment should be carried out when workers are disturbing asbestos to ensure that they are not exposed to airborne asbestos concentrations greater than the Permissible Exposure Limit (PEL) of 0.1 fibers per cubic centimeter (f/cc) of air as an 8-hour time-weighted average (TWA), and the Excursion Limit of 1.0 f/cc over a 30-minute sampling period.

The work site must be maintained as a controlled regulated area and supervised by a competent person at all times.

Employees must implement stringent dust control procedures to prevent asbestos in any airborne or settled dust.

Employees must clean the work area thoroughly using wet methods and a high-efficiency particulate air (HEPA) vacuum. Dry sweeping or air blowing of asbestos-containing debris and dust must be avoided.

Waste and dust containing asbestos must be collected separately from other construction debris. Workers must conduct prompt and controlled clean up and disposal of asbestos wastes and debris in leak-tight containers.

Asbestos-containing waste must be wet, packaged, labeled, stored, and disposed of in accordance with applicable regulations.

2735_1 7 Myounghee Noh & Associates, L.L.C.

Visually inspect the work area to ensure that all asbestos-containing debris and dust has been properly removed.

Conduct clearance in accordance with contract specifications.

8.2 Lead-Containing Paints

Based on the sampling and analysis of four suspected lead paints in Building 51109, no LCP were identified in the project area during this survey. Therefore, no special lead control measures are provided; however, Contractors must review the Safety Data Sheet of the existing paint coatings to determine all appropriate demolition or renovation procedures, and design and implement engineering controls to prevent any releases of the potential contaminants in the paint coatings.

10.3 Arsenic-Containing Materials

No suspected arsenic-containing materials were identified in the project areas during this survey.

Therefore, no special arsenic control measures are provided.

9.0 LIMITATIONS

Industry standard effort was made to identify suspected hazardous building materials during the survey at the project area. However, this does not imply a guarantee that all suspected building materials and hazardous materials were identified by this assessment because certain building materials and/or surfaces may be hidden by walls, flooring/concrete slab, partitions, other building components, or existing equipment or furniture. If any previously unforeseen suspected materials become known, such as any hazardous chemicals in the lead-free paint coatings, additional assessment may be required prior to the planned building modification project.

Material quantities provided in this report are based on visual approximations taken at the time of the survey only and should not be used for bidding purpose. It is the Contractor’s responsibility to verify the material quantities and volume of waste prior to bidding.

Analytical results provided in this report do not meet the requirements for waste characterizations.

Contractor must coordinate with permitted landfills for required waste characterizations.

Any ACM disturbance exceeding 3 square feet or 3 linear feet of friable ACM or generating 0.5 cubic feet of ACM debris is considered a regulated activity. Contractors are required to comply with 29 CFR 1926.1101(k)(3)(i) to identify the presence, location, and quantity of ACM before any work is begun.
