Limited Hazardous Materials Survey – AKS Architecture NOAA Hangar 32 i

EXECUTIVE SUMMARY

AKS Architecture has contracted EHS-International, Inc. (EHSI), a hazardous materials and industrial hygiene consulting firm, to conduct a Limited Hazardous Materials Survey of AKS NOAA Hangar 32 located at 7600 Sand Point Way NE, Seattle, Washington (Site). EHSI understands that the survey will be used in project planning for upcoming renovation of the Site.

The limited hazardous materials survey included asbestos-containing materials (ACM); regulated-metals-containing paint (RCRA-8); polychlorinated biphenyl (PCB)-containing paint, light ballasts, and bulk materials; mercury-containing fluorescent light tubes, freezers/fridges, and thermostats; and other regulated materials. This survey was performed in accordance with federal, state, and local regulatory requirements. Each regulated material included in the survey is summarized below.

Previous Reports

EHSI reviewed the following reports in preparation for this survey:

• Raven Services Corporation – Asbestos Management Report, 1/20/98

• Unknown – NOAA WRC ACBM Location CAD Interior 2/24/20

• Ahtna Global, LLC – Good Faith Survey, Hangar 32 Reroofing, 3/17/21

Asbestos-Containing Building Materials

EHSI collected one hundred eighty-nine (189) bulk samples of suspect ACM at the Site along with an additional ten (10) quality assurance samples. Many of those samples were found to contain asbestos, while other materials that could not be sampled were assumed to contain asbestos. Several of the materials sampled that do not contain asbestos are adhered to ACM and must also be assumed to be contaminated with asbestos in the event those materials are removed or disturbed during demolition.

Specific sample locations of the suspect materials can be referenced in sample location figures SL-1 through SL-6.

The following summary of ACMs and assumed ACMs were identified by EHSI sampling.

• 2,500 Square Feet (SF) – ACM Vinyl asbestos tile (VAT) (multiple sizes/colors) on ACM mastic (black) on concrete throughout

• 3,700 SF – ACM VAT (tan/gray/green) with ACM mastic (black) beneath various non-ACM carpet flooring and non-ACM mastic on concrete throughout

• 3,725 SF – ACM Black Mastic beneath various non-ACM carpets/tiles, on concrete throughout

• 8,750 SF – Flat Transite Panels on walls interior of hangar

• 7,500 SF – Corrugated Transite Panels on exterior of hangar (quantity not given in cost estimate)

• 11,200 SF – Joint Compound on Gypsum Wallboard (GWB), with white paint (<1%)

• 1,650 SF – White Skim Coat on corner joints of door/window frames

• 16,000 Lineal Feet (LF) – White/brown window frame glazing around edges of windowpanes on exterior

• 3,000 LF – White window edge frame caulking, between windows/doors and transite on exterior

• 1,500 LF – ACM Thermal System Insulation (TSI) on piping 8” or less

• 150 SF – ACM black countertops, resting atop tan metals shelves

• 1 EA - 12” Diameter– ACM black steam tank gasket ii

• 54 LF – ACM brown window frame caulking, inside windows in two locations

• 20 EA – ACM white window glazing, interior in one room

• 68 LF – ACM yellow toilet caulking, present in restrooms

• 4 EA – ACM electrical panels with Cement Asbestos Board (CAB) backer and interior components

• 20 EA – ACM electrical junction boxes with Cement Asbestos Board (CAB) backer and interior components (multiple sizes throughout)

Hazardous Metals-Containing Paint

EHSI completed a limited HMCP assessment of the proposed work area and specific materials expected to be impacted through the collection and analysis of eleven (11) paint chip samples. Detectable levels of

Arsenic (As), Barium (Ba), Cadmium (Cd), Chromium (Cr), Mercury (Hg), and Lead (Pb) were found in the paint chip samples analyzed as a part of this limited hazardous building material survey.

The US Occupational Safety and Health Administration (OSHA) requires employers to conduct a hazard assessment and take appropriate worker protection precautions whenever building materials are disturbed that have detectable quantities of hazardous metals. EHSI recommends that the provided paint chip sample results be used in conjunction with other applicable (e.g., air monitoring) data to evaluate the potential for elevated occupation lead and RCRA 8 metal exposures during demolition activities.

Polychlorinated Biphenyl Light Ballasts, Mercury, and Other Regulated Materials

As part of our survey for regulated materials, EHSI quantified the number of light ballasts and prepared an inventory of other installed regulated materials that may classify as universal hazardous wastes or other regulated wastes. These materials included PCB-containing paint, mercury-containing items such as fluorescent light tubes, high-intensity discharge lighting, thermostats, and switches. All identified magnetic ballasts are assumed to contain PCBs. A similar assumption applies to mercury potentially present within fluorescent lamps and fluorescent light fixtures. Generally, it is not necessary to sample these materials because their presence within the building represents a future cost for disposal of the facility’s installed contents.

The following regulated materials were identified at throughout Site described below:

• Potential mercury-containing fluorescent light tubes: 110 EA

• Potential PCB-containing light ballasts: 45 EA

• Stand-Alone refrigerator freezer or chest freezer with CFC units: 3 EA

• Walk-In freezers/coolers with CFC units: 2 EA

• Mercury-containing Thermostats: 10 EA

• PCB-containing paint: Throughout (see tables for exact paint colors) iii

INTRODUCTION

AKS Architecture has contracted EHS-International, Inc. (EHSI), a hazardous materials and industrial hygiene consulting firm, to conduct a Limited Hazardous Materials Survey of AKS NOAA Hangar 32 located at 7600 Sand Point Way NE, Seattle, Washington (Site). EHSI understands that the survey will be used in project planning for upcoming renovation of the Site.

The limited hazardous materials survey included asbestos-containing materials (ACM); regulated-metals-containing paint (RCRA-8); polychlorinated biphenyl (PCB)-containing paint, light ballasts, and bulk materials; mercury-containing fluorescent light tubes, freezers/fridges, and thermostats; and other regulated materials. This survey was performed in accordance with federal, state, and local regulatory requirements. Each regulated material included in the survey is summarized below.

1.1 Scope of Work

The scope of services for the limited hazardous materials survey included the following tasks:

• Collect bulk suspect ACM samples as necessary to identify ACM within the Site building. Where bulk sampling or access is not possible, review available historical drawings and make inventory assumptions to the likely quantities of ACM that can be assumed.

• Collect limited LCP chip samples of common color paints on representative building components and have them analyzed for lead.

• Inventory universal wastes such as potential PCB-containing lighting ballasts; mercury-containing fluorescent light tubes; high pressure sodium lamps; mercury-containing fluorescent light tubes, switches, and thermostats.

• Prepare a summary report documenting the findings of the survey and provide tables summarizing hazardous materials, analytical data, comments and recommendations for handling and control.

1.2 Building Description

The following is a listing of the areas (units) that are found at the Site and are further shown on Figure SL, overall site plan.

• North Lean-To

• Center Hangar

• South Lean-To

Both Lean-To’s are four (4) stories high, with the third and fourth floors being primarily comprised of a stairwell and a single room at each corner of the building. The South Lean-To has a gross square footage of approximately 11,200 square feet. The North Lean-To is nearly identical in structure except for an additional interior, for a gross total of 17,600 square feet. Between both Lean-To’s is the Center Hangar, a mostly open area containing several storage structures and various operational machinery, with a gross square footage of 73,600 square feet.

1.3 Limitations

The conclusions of the report are professional opinions based solely upon visual site observations, and interpretations of sample analyses as described in this report. The opinions presented herein apply to conditions existing at the time of the investigation, and interpretation of current regulations pertaining to

ACMs. Therefore, opinions and recommendations provided herein might not apply to future conditions that may exist at the Site. Current applicable regulations should always be verified prior to any work involving asbestos or other regulated materials. This survey is not intended to be used as an abatement design document. All existing conditions, quantities, and locations should be verified prior to abatement.

ACM may be located within areas that were not accessible during this survey. The survey did not include an investigation of potentially buried piping within or in the vicinity of the structures.

The purpose of the limited hazardous material survey is to reasonably test for evidence of asbestos and other hazardous materials in suspect or randomly selected materials at a facility. It should be noted that no survey can be comprehensive or exhaustive enough to eliminate the possibility that ACM present at the Site may not be detected during the survey. Therefore, the completion of this or any survey for ACM or other hazardous materials should not be considered a warranty or guarantee that these materials do not exist, even if they are not detected through a survey.

The survey did not include sampling of the following materials or locations at the Site due to limited access:

• Materials associated with energized electrical equipment (e.g., wiring and panel boards) and transformers

• Buried piping

• Gaskets or packing materials in closed equipment

• Built-up roofing system

Due to the age of the buildings on the Site, it is possible that materials associated with the above-noted structures/systems may be asbestos-containing. If suspect materials are determined to be present within the above-noted systems, the materials should be considered as presumed ACMs until proven otherwise by sampling and laboratory analysis.

METHODOLOGY

Information concerning the Site was obtained from site inspections conducted by EHSI employees including Mr. Sunny Joshi and Mr. Matt Macfarlane. Copies of their AHERA building inspector certifications are included in Appendix A. This section describes the sampling methodology and applicable asbestos regulations.

2.1 Asbestos Survey Methodology

A visual inspection of accessible areas was conducted to identify suspect ACM and assumed ACM. The asbestos survey was performed by AHERA-certified building inspectors in accordance with a sampling protocol appropriate for the demolition of the Site building. The sampling protocol was developed in accordance with the following:

• U. S. Environmental Protection Agency (EPA) Asbestos Regulation within the Toxic Substances Control Act (40 Code of Federal Regulation [CFR] 763)

• Puget Sound Clean Air Agency (PSCAA) Asbestos Control Standards (Regulation III, Article 4), and

• Washington State Department of Labor and Industries Asbestos, Tremolite, Anthophyllite, and Actinolite Regulation (WAC 296-62-077).

The sampling plan included, at a minimum, the collection and analysis of samples as follows:

• Thermal system insulation (TSI): EHSI collected a minimum of three samples in a distributive manner from each homogeneous sampling area not presumed to contain asbestos. At least one bulk sample of patched TSI was collected from each homogenous area, if the patch was less than 6 square feet in area.

• Surfacing material: EHSI collected a minimum of three samples in a distributive manner from each homogenous area that was 1,000 square feet or less in area. A minimum of five samples were collected from each homogenous area that was more than 1,000 square feet but less than or equal to 5,000 square feet in area. A minimum of seven samples were collected from each homogenous area that was more than 5,000 square feet in area.

• Miscellaneous material: EHSI collected bulk samples of suspect ACM in a distributive manner as deemed sufficient by the AHERA-certified building inspector. At least one sample was collected of each suspect miscellaneous material not presumed to contain asbestos.

• Non-suspect materials: According to 40 CFR 763-86(4), where the accredited inspector has deemed the material to be fiberglass, foam glass, rubber, or other recognized non-ACM, sampling is not required.

Samples were collected by carefully removing small portions of the suspect material with a sharp knife or other hand tool suitable for the material being sampled. The sampling instrument was wiped with a clean moist cloth to decontaminate the tool and minimize the potential release of asbestos fibers or cross-contamination of subsequent samples. Once collected, each bulk sample was sealed in a new clean plastic bag to eliminate the possibility of cross-contamination, labeled with the sample name, and shipped to the analytical laboratory under standard chain-of-custody protocols. Bulk ACM sample locations are illustrated in Figures SL-1 through SL-22.

2.1.1 Sample Documentation

A unique sample identification system was employed for bulk samples of suspect ACMs collected during the survey that includes the project number, and sample sequence number.

Example: 11527-A - 001QA

Data pertinent to each sample (e.g., date, sample name, material description, and material category) was recorded on a field data sheet. The material determination of friability was made by the AHERA-certified building inspector in the field. Details regarding the bulk samples of suspect ACMs and their friability are summarized in Table 1.

2.1.2 Laboratory Analysis

As specified in 40 CFR 763.87, each sample was analyzed using polarized light microscopy (PLM) with dispersion staining in accordance with EPA Method 600/R-93/116. Samples were analyzed for asbestos

EHSI Project Number Sample Sequence Number

“QA” added on designated quality assurance samples only

Unit Name content by Seattle Asbestos Test, LLC (SAT) in Seattle, Washington. SAT participates in the National

Institute for Standards and Technology National Voluntary Laboratory Accreditation Plan (NVLAP). Only materials containing greater than 1% total asbestos were classified as “asbestos-containing” based on

EPA, state, and local regulations.

Split samples were collected from some same locations for the purposes of quality assurance (QA) and sent to a separate laboratory for analysis. QA samples were submitted to NVL Laboratories, Inc. (NVL) in

Seattle, Washington. NVL is also a NVLAP-accredited laboratory.

Laboratory analytical reports and chain-of-custody forms are provided in Appendix B. Laboratory certifications are provided in Appendix C.

2.2 RCRA Metals Survey

EHSI collected bulk samples to determine the RCRA Metals content of interior and exterior painted coatings. Once collected, each bulk sample was sealed in an unadulterated plastic bag to eliminate the possibility of cross-contamination. “Chain-of-Custody” tracking was followed to maintain sample integrity during handling and data reporting at EHSI and the analytical laboratory. The bulk samples were taken for a representative number of LBP and LCM and were sent to NVL located in Seattle, Washington, an accredited laboratory.

2.2.1 Sample Documentation

A unique sample identification system was employed for paint chip samples that included the project number, chemical abbreviation for lead, and sample sequence number.

The paint chip samples were analyzed in accordance with EPA Method 3051/7000B by NVL. NVL participates in the National Environmental Laboratory Accreditation Program and employs American

Industrial Hygiene Association quality control procedures.

A summary of bulk lead paint results is provided in Table 10. Laboratory analytical reports and chain-of-custody forms are provided in Appendix B. Laboratory certifications are provided in Appendix C.

2.3 PCB Survey

The PCB survey consisted of EHSI collecting a minimal number of representative suspect samples. EHSI collected twelve (11) samples during the limited hazardous building material survey. Mortar samples were obtained by using a chisel to break off a corner of BMU or CMU with mortar. Approximately ½ cubic inch of mortar was removed for each sample. Samples were then placed into 2-ounce, puncture-proof, polyethylene bags, labeled with sample name, and placed in a box for shipping to the analytical laboratory

2.4 Visual Survey of PCBs, Mercury, and Other Regulated Materials

Verifying the presence or absence of PCBs, mercury, or other regulated materials by laboratory analysis, was beyond the scope of this survey. The survey did include visual identification and determination of quantities of potentially PCB-containing fluorescent light ballasts or transformers. All the ballasts were assumed to contain PCBs. A similar assumption applies to mercury potentially present within fluorescent lamps in fluorescent light fixtures, high intensity discharge (HID) lamps, and thermostats.

3.2 RCRA-8 (Total Metals and TCLP)

EHSI collected eleven (11) paint chip samples from the Site. Analysis of the paint chip samples shows detectable levels of Arsenic, Barium, Cadmium, Chromium, Mercury, and Lead. The paint chip analytical results are included in Tables 2 and 4. A copy of the laboratory analytical report and chain-of-custody form for RCRA/TCLP bulk samples are included in Appendix B.

3.3 PCB’s

EHSI collected twelve (11) paint chip samples from the Site. Analysis of the paint samples shows results below the limit of detection to detectable levels of 15.4 mg/Kg. The summary of PCB analytical results is included in Table 3.

A copy of the laboratory analytical report and chain-of-custody form for PCB samples are included in

Appendix B.

3.4 PCBs, Mercury, and Other Regulated Materials

A tabulated summary of fluorescent light ballasts, mercury-containing light tubes, HID lamps, fire alarm control panels with Lead-acid batteries, and thermostats are provided in Table 5.

CONCLUSIONS AND RECOMMENDATIONS

A copy of this report must be provided to any contractor bidding and/or conducting work at the Site. The contractor must also have a copy of this report during demolition activities at the Site. Conclusions and recommendations for each regulated material category are summarized below.

4.1 Asbestos-Containing Materials

ACMs were identified at AKS NOAA Hangar 32. An asbestos abatement contractor licensed in accordance with WAC 296-62-077 and PSCAA Regulation III, Article 4 must remove all asbestos-containing and asbestos contaminated building materials prior to demolition.

The contractor should also use caution when performing demolition activities within the project areas even after asbestos abatement activities have been conducted. Concealed materials may be encountered during a renovation or demolition project. ACM may be located between walls, in pipe chases, between pipe flanges or other inaccessible areas.

If additional suspect building materials not identified specifically in this report as either ACM or non-

ACM are identified during demolition activities, they should be treated as ACM until sampled by an

AHERA-certified building inspector and proven to not contain asbestos through laboratory analysis.

4.2 Lead Paint

Based on sampling results, EHSI recommends treating all painted surfaces as having paint with detectable concentrations of lead. The Washington State Department of Commerce defines LCP as coatings with a concentration of lead greater than or equal to 0.5 percent by weight. However, the U.S.

Department of Labor and the Washington State Department of Labor and Industries require that the

Washington State Construction Standards for Lead (WAC 296-155-176) be followed during “new construction, alteration, repair, or renovation of structures, substrates, or portions thereof that contain lead, or materials containing lead.” These standards consider any detectable concentration of lead to be a potential hazard during construction activities.

The Washington State Department of Labor and Industries considers any detectable concentration of lead to be a potential hazard during construction activities. Based on the limited testing of painted surfaces completed by EHSI, EHSI recommends assuming all painted surfaces in the project area contain at least detectable levels of lead. Most of the paint coatings were found to be in good condition. EHSI recommends that the contractor use precautions and follow applicable health and safety guidelines when removing materials during asbestos abatement activities, building renovation, or demolition.

For work on building components containing lead or other heavy metals, which may result in personnel exposures, the contractor must assess the hazard. Based on the assessment, and previous similar work and exposure monitoring results, the contractor may have to provide any or all the following for employees per WAC 296-155-176:

• Respiratory protection.

• Protective clothing.

• Clean change areas.

• Clean handwashing facilities.

• Biological monitoring to consist of blood sampling and analysis for lead and zinc protoporphyrin levels; and

• Hazard communication training.

Initial employee exposure monitoring must be conducted for each separate task involving the handling of LCP-coated building materials. If 8-hour time-weighted average exposures exceed the action level of

30 micrograms per cubic meter, the contractor must continue to conduct periodic air monitoring at specified intervals, and institute medical surveillance and comprehensive training programs. If the OSHA

8-hour time-weighted average permissible exposure limit of 50 micrograms per cubic meter of lead is exceeded, more stringent and additional requirements become effective, such as engineering controls, respiratory protection, regulated work areas and warning signs in lead work areas.

The general contractor performing demolition work should be informed of the presence of lead in the project area. All personnel impacting LCP (or other lead-containing materials) should be provided additional training concerning the health effects of lead, proper work methods, appropriate use of personal protective equipment, and regulations governing lead exposures. Air monitoring to assess lead exposures should be performed for all personnel involved in the demolition process where LCP may be removed.

4.3 PCBs, Mercury, and Other Regulated Materials

4.3.1 Polychlorinated Biphenyl Light Ballasts

The Washington State Dangerous Waste Regulation, WAC 173-303, designates that discarded transformers, capacitors, or bushings containing PCBs at concentrations of 2 parts per million or greater be treated as a PCB-containing material. Light ballasts fall under this regulation. Previous regulations dictated that any material with less than 50 parts per million of PCBs could be labeled as a non-PCB-containing material. Because of this regulatory change, EHSI recommends that all light ballasts be tracked, removed, handled, and disposed of in an appropriate manner. Ballasts with a label stating, “NO

PCB” (or something similar) shall be packaged for recycling by an approved recycling facility.

4.3.2 Mercury

Many fluorescent light tubes, HID lamps, thermostats, and switches contain mercury that is harmful to the environment and human health. The EPA and Washington State Department of Ecology have placed these materials in a special category of dangerous waste known as universal waste. Some of the requirements included within the Standards for Universal Waste Management (WAC 173-303-573) include:

• Immediately place lamps showing evidence of leakage, damage, etc. into a container following removal.

• Containerize in closed, structurally sound, compatible containers. Cardboard containers may be used for inside storage only.

• Labeling container as follows: “Waste Lamps,” or “Universal Waste Lamps”.

• Track the length of time since waste lamp generation. Acceptable methods of proof include date on label, inventory system, etc.

• Respond immediately to potential releases. If determined to be a release, contain, and determine if it designates as a dangerous waste.

• Disposal of universal waste as general or construction debris is not permitted.

• The crushing of fluorescent light tubes on-site is not allowed. In addition, measures should be taken to prevent breakage of fluorescent light tubes while the light tubes are in transit to their destination.

• Provide training to employees on the proper handling and emergency procedures for universal waste lamps.

• Track shipments of universal waste lamps with records (invoice, manifest, etc.) kept for a minimum of 3 years.
