Hazardous Building Materials Assessment
City of Edmonds — 9309 Bowdoin Way, Edmonds, WA 98020
EXECUTIVE SUMMARY
The City of Edmonds retained DH Environmental, Inc. (DH Environmental) to conduct a hazardous building materials
assessment for the building located at 9309 Bowdoin Way in Edmonds, WA. DH Environmental provided one AHERA
accredited building inspector to conduct the assessment on May 4th, 2023. The scope of the services included
assessing the building for hazardous building materials in anticipation of the forthcoming renovation.
DH Environmental assessed the building for the following hazardous building materials:
■ Asbestos -containing materials (ACM);
■ Lead -based paints (LBP)
■ Polychlorinated Biphenyls (PCBs)
■ Other hazardous building materials (household hazardous waste and refrigerant gases)
Nineteen (19) bulk samples of suspect asbestos -containing materials were collected and analyzed using polarized
light microscopy (PLM). Five (5) of the samples were found to contain asbestos greater than 1%. Building materials
that contain greater than 1% asbestos are considered "Asbestos Containing Materials" by regulatory definition.
Ninety-two (92) locations in the building were analyzed using an X-ray fluorescence analyzer (XRF). Thirty-five (35)
of the locations were found to contain lead above the Federal lead -based paint concentration criteria of 1 mg/cm'.
Other hazardous materials such as household hazardous waste, one refrigerator and one freezer were identified
during the inspection and are inventoried in the report.
One sample of suspected PCB containing paint were collected and analyzed for PCBs by EPA Method 8082. The
sample was below the regulatory limit of 50 mg/kg for PCBs.

Hazardous Building Materials Assessment
City of Edmonds — 9309 Bowdoin Way, Edmonds, WA 98020
1.0 INTRODUCTION
The City of Edmonds retained DH Environmental, Inc. (DH Environmental) to conduct a hazardous building materials
assessment of the building located at 9309 Bowdoin Way in Edmonds, WA. DH Environmental provided two AHERA
accredited building inspectors to conduct the assessment on May 4th, 2023.
1.1 Scope of Services
The scope of the services included assessing parts of the home and outbuilding for hazardous building materials in
anticipation of a forthcoming demolition in accordance with 40 CFR 763, Puget Sound Clean Air Agency Regulation
III, Article 4.02(a), and the Washington State Dangerous Waste Regulations (WAC 173-303).
DH Environmental assessed the building for the following hazardous building materials:
■ Asbestos -containing materials (ACM)
■ Lead -based paints (LBP)
■ Polychlorinated Biphenyls (PCBs)
■ Other hazardous building materials:
• refrigerant gases (CFCs)
• household hazardous waste
1.2 Assessment Objective
The objective of this hazardous building materials assessment is to assist the City of Edmonds with communicating
the presence of hazardous building materials and the presence, location, and quantity of ACM to employees,
vendors, and contractors working in the project area. In addition, this assessment is meant to satisfy the
requirements for an asbestos survey for the Puget Sound Clean Air Agency (PSCAA) and a good faith inspection as
required by Washington State Department of Labor and Industries' Division of Occupational Safety and Health
(DOSH) regulations prior to building demolition or renovation. Regulations require that a complete copy of this
assessment be kept in a conspicuous location on -site at all times during activities that may impact known and
suspect ACM.

3.0 ASBESTOS CONTAINING MATERIALS ASSESSMENT
3.1 Applicable ACM Regulations
The Washington State Department of Labor and Industries' Division of Occupational Safety and Health (DOSH) and
the Puget Sound Clean Air Agency regulate building materials that contain more than 1 percent asbestos as ACM
for protection of human health and the environment.
DOSH regulates worker exposure to airborne asbestos fibers during general work activities and construction and
demolition activities (WAC 296-62-077). Worker exposure to airborne asbestos fibers must be below the
Permissible Exposure Level (PEL) of an 8-hour time -weighted average (8-hr TWA) of 0.1 fiber per cubic centimeter
(f/cc) of air. DOSH regulations establish engineering controls and work practices that are designed to mitigate
workers exposure to asbestos in the workplace.
The Puget Sound Clean Air Agency (PSCAA) regulates the release of airborne asbestos fibers in King County and
surrounding areas. Specifically, PSCAA under Article IV, Regulation III regulates emissions of asbestos during
building renovation and demolition projects. This regulation requires that an asbestos survey be conducted prior
to demolition, that PSCAA be notified prior to commencing with demolition activities, that ACM be removed prior
to demolition, and that asbestos -containing waste materials be properly removed and disposed of in a manner
that prevents the release of airborne asbestos fibers. In addition, the United States Environmental Protection
Agency (USEPA) requires asbestos abatement workers and supervisors to be trained and certified in accordance
with 40 CFR 763 Subpart E, Appendix C. DOSH has analogous training requirements for abatement workers in WAC
296-65. The EPA and DOSH training and certification requirements apply to abatement work for buildings at the
subject property.
3.2 Sampling Methodology
The ACM sampling methodology conducted for this assessment was conducted in accordance with Puget Sound
Clean Air Agency Guidance Document 66-149, Asbestos Survey Guidance Rev. 2., as well as related AHERA
Protocols. A site walk was conducted with the Owner's Project Engineer prior to conducting the assessment.
All areas of the interior and exterior were investigated thoroughly looking for suspected ACM. Destructive sampling
was needed in some areas to help identify building material components (e.g., insulation that was found behind
the walls). Where appropriate, suspect ACM was grouped as homogenous if the materials were similar in
appearance.
Samples were collected, containerized, and delivered to NVL Environmental Laboratories in Seattle, WA following
standard chain of custody procedures. Suspect ACM samples were analyzed per EPA Method 600/R93/116 by
Polarized Light Microscopy (PLM) analysis. NVL is a National Voluntary Laboratory Accreditation Program (NVLAP)
— certified laboratory, certification number 102063-0 (see attachment 4).

City of Edmonds — 9309 Bowdoin Way, Edmonds, WA 98020
4.0 LEAD BASED PAINT (LBP) ASSESSMENT
4.1 Applicable LBP Regulations
DOSH regulates exposure of workers in general industry (WAC 96-62-07521) and construction workers (WAC 296-
155-176) to lead in the workplace. The regulations provide engineering controls and work practices to minimize
worker exposures. These regulations are applicable to renovation/demolition activities that have the potential to
expose workers to airborne concentrations of lead at or above the 8-hr time weighted average (TWA) action level
of 30 micrograms per cubic meter (ug/m3) of air. Workers must not be exposed to lead at concentrations greater
than the permissible exposure limit (PEL) of 50 ug/m3 for an 8-hr TWA. Employers are responsible for determining
whether their employees will be exposed to lead. A negative exposure assessment is required, consisting of
modeling or air monitoring to verify that workers are not being exposed above the action level. If an exposure
assessment cannot be conducted for demolition activities, workers coming into contact with deteriorated paint and
paint dust should wear a half -face respirator with a particulate cartridge, coveralls or similar full -body work clothing,
gloves, safety glasses, and shoes or disposable shoe coverlets. If the negative exposure assessment reveals that
workers are exposed to lead dust above the PEL, the requirements of WAC 296-62-07521 must be implemented,
including training, air monitoring, and medical surveillance.
The USEPA regulates LBP activities in residential target housing (40 CFR 745, Subpart Q. These regulations include
both training and certification requirements for persons involved in LBP activities in target housing, as well as work
practice standards for conducting LBP inspections, risk assessments, and abatement activities. The regulations
under 40 CFR 745, Subpart L do not apply to LBP activities to be conducted on the subject property.
The USEPA and Washington State requires generators of solid waste to determine whether their waste is a
dangerous waste for proper accumulation, transportation, and disposal. For demolition debris -related waste that
potentially contains lead or other heavy metals, a representative sample(s) of the debris must be analyzed by the
Toxicity Characteristic Leachate Procedure (TCLP) in accordance with WAC 173-303-090. Solid wastes containing
leachable lead detected at a concentration of 5 mg/L or greater must be accumulated, stored, transported and
disposed of as dangerous waste. Scrap metal that will be recycled is exempt from regulation as a Dangerous Waste
in accordance with WAC 173-303-071(ff).
4.2 LBP Sampling Methodology
The testing of suspected lead painted surfaces was conducted by portable XRF lead -based paint analyzer. XRF
instruments expose a building component to electromagnetic radiation in the form of X-rays or gamma radiation.
In response to radiation, each element, including lead, emits energy at a fixed and characteristic level. Emission of
characteristic x-rays is called "X-Ray Fluorescence," or XRF. The energy released is measured by the instrument's
fluorescence detector and displayed, all of the inconclusive ranges and/or thresholds are based on 1.0 mg/cm'. The
lead -based paint inspection is in accordance with the methodologies set forth by the U.S. Department of Housing
and Urban Development (HUD), and manufacturer's guidelines.
Locations of the areas tested are shown in Figure 2.

5.0 POLYCHLORINATED BIPHENYLS (PCBs) ASSESSMENT
5.1 Applicable PCB Regulations
Common PCB building materials include caulking, paint and adhesives. Current regulations require the removal of
building materials containing PCBs if found with concentrations of 50 parts per million (ppm) or greater.
Reinforcing this regulatory interpretation, EPA's current policy is clearly stated on the agency's website under a
page titled Current Best Practices for PCBs in Caulk Fact Sheet - Removal and Clean -Up of PCBs in Caulk and PCB -
Contaminated Soil and Building Material' . The website states the following: "Caulk containing PCBs at
concentrations > 50 ppm is not authorized for use and must be removed and properly disposed. When disposed,
the caulk must be managed as PCB bulk product waste, defined at 40 CFR §761.3. Regulations governing the
cleanup and disposal of PCB bulk product waste are provided at 40 CFR §761.62. PCB -containing caulk or caulk
coated building material containing PCBs at concentrations > 50 ppm must be removed unless otherwise approved
by EPA under a risk -based disposal approval issued under 40 CFR § 761.62(c)."
PCBs are also contained within the fluorescent lamp capacitors and interior potting material of old, magnetic
lighting fixtures. The capacitor regulates the amount of electricity flowing into the lighting fixture, and the potting
material insulates the FLB and reduces the "humming" noise. Because all PCB -containing fluorescent light ballasts
currently in use have exceeded their designated life span, they are susceptible to leaking or rupturing. This may
lead to increased exposure to building occupants. Residues from these sources are difficult and costly to clean up.
Additionally, intact PCB -containing fluorescent light ballasts may emit small amounts of PCBs into the air during
normal use of the lighting fixtures.
EPA recommends all PCB -containing fluorescent light ballasts be removed from lighting fixtures. The fluorescent
light ballasts and capacitors are regulated in concentrations greater than 50 mg/kg by the USEPA, and at
concentrations greater than 2 mg/kg by the Washington State Department of Ecology. In accordance with 40 CFR
761.2, "any person must assume that a capacitor manufactured prior to July 2, 1979, whose PCB concentration is
not established contains >_500 ppm PCBs. Any person may assume that a capacitor manufactured afterJuly 2, 1979,
is non -PCB (i.e., <50 ppm PCBs). If the date of manufacture is unknown, any person must assume the capacitor
contains >_500 ppm PCBs. Any person may assume that a capacitor marked at the time of manufacture with the
statement "No PCBs" in accordance with § 761.40(g) is non -PCB."
5.2 PCB Sampling Methodology / Findings
Fluorescent lights were observed during the assessment but were not able to be accessed to verify that light ballasts
say, "no PCBs". Careful inspection of each ballast in the building should be conducted upon removal to ensure
proper management of the ballasts. If any of the ballasts do not contain the words "no PCBs" and were

manufactured before July 2, 1979, they must be assumed to contain PCBs unless sampling confirms they do not. In
addition, employers must inform their employees of PCB hazards in accordance with WAC 296-800-170.
5.3 PCB Sampling Results
One sample of suspected PCB containing caulking was collected and analyzed for PCBs by EPA Method 8082. The
sample was below the regulatory limit of 50 mg/kg for classification as PCB Bulk Product Waste. The location of the
sample collection is shown in Figure 2. Table 3 below shows the results of the PCB sample.

Hazardous Building Materials Assessment
City of Edmonds — 9309 Bowdoin Way, Edmonds, WA 98020
6.0 OTHER HAZARDOUS BUILDING MATERIALS ASSESSMENT
A visual inspection was conducted to inventory other hazardous building materials. Other hazardous building
materials assessed included universal waste, refrigerant gases, propane cylinders, and fire extinguishers.
6.1 Universal Waste
Universal waste is a category of dangerous waste that allows all businesses to handle several common types of
dangerous waste under simplified rules. Managing these materials as universal waste means that they are not
counted toward your generator status or reported on your Dangerous Waste Annual Report. In Washington State,
five categories of waste can be managed as universal waste:
■ Batteries;
■ Lights, lamps, light bulbs, and light tubes;
■ Mercury -containing thermometers;
■ Mercury -containing thermostats;
■ Mercury -containing switches and relays.
If any of these materials are identified for disposal for the demolition or renovation project, the materials should
be removed, packaged, and recycled as universal waste.
6.2 Refrigerant Gases
Section 608 of the Federal Clean Air Act prohibits individuals from intentionally venting refrigerants into the
atmosphere while disposing of refrigeration/AC equipment. "De minimis" quantities of refrigerant released in the
course of making good faith attempts to recapture and recycle or safely dispose of refrigerant are not subject to
this prohibition (40 CFR 82.154[a][2]). To implement the venting prohibition, Section 608 specifies evacuation level
requirements (40 CFR 82.156) and refrigerant recovery equipment requirements (40 CFR 82.158) for both small
appliances and other refrigeration/AC equipment. When demolishing or renovating a structure, the following
equipment should be assessed to determine the need for evacuation, recovery, or disposal by a licensed technician:
Small Appliances
A small appliance is defined as any appliance that is fully manufactured, charged, and hermetically sealed in a
factory with five pounds or less of a CFC or HCFC refrigerant, including the following:
■ Refrigerators and freezers (designed for home, commercial, or consumer use);
■ Medical or industrial research refrigeration equipment;
■ Room air conditioners (including window air conditioners and packaged terminal air heat pumps);
■ Under-the-counter ice makers;
■ Vending machines; and
■ Drinking water coolers.

City of Edmonds — 9309 Bowdoin Way, Edmonds, WA 98020
All Other Equipment
All other equipment refers to all appliances except for small appliances, motor vehicle air conditioners (MVACs),
and MVAC-like appliances. Specifically, this equipment includes:
■ Chillers;
■ Industrial refrigeration equipment (not including research equipment);
■ Refrigerant fire suppression systems;
■ Commercial refrigeration equipment; and
■ Cold storage equipment.
6.3 Fire Extinguishers
Dry chemical and liquid fire extinguishers may designate as dangerous waste if they are disposed of as solid waste.
Fire extinguishers should be removed from service prior to demolishing or renovating the area where the fire
extinguishers are mounted or stored. If the fire extinguishers cannot be recycled or reused, they must be designated
and disposed of accordingly.
6.4 Radioactive Exit Signs and Smoke Alarms
Many exit signs and smoke alarms contain low-level radioactive sources that should be managed in accordance
with Nuclear Regulatory Commission Regulations. Accredited mail -in programs are available to recycle these
materials. Radioactive exit signs and smoke alarms should be identified for removal and recycling or disposal prior
to renovation or demolition of the building or affected area.
6.5 Summary of Other Hazardous Building Materials
This hazardous building materials assessment identified fluorescent light tubes, high intensity discharge lamps,
refrigerant gases, mercury thermostats, propane tanks, and fire extinguishers that should be removed and reused,
recycled, or disposed of prior to the renovation project. No radioactive exit signs or smoke alarms were identified.

7.0 CONCLUSIONS AND RECOMMENDATIONS
7.1 Asbestos Containing Materials
ACM was detected in some of the areas where the work was understood to be conducted. Therefore, we
recommend that this work should be considered an "Asbestos Project" as defined in the Puget Sound Clean Air
Agency Regulation 3, or WAC 296-62-07701.
7.2 Lead Based Paint
Lead paint was detected in some of the building materials sampled. Therefore, we recommend implementation of
engineering and work practice controls to reduce and maintain employee exposure to lead to or below the
permissible exposure limitz to the extent that such controls are feasible in accordance with WAC 296-155-17611.
7.3 Polychlorinated Biphenyls
One (1) sample of suspected PCB containing caulking was collected and analyzed for PCBs by EPA Method 8082.
The sample was below the regulatory limit of 50 mg/kg for PCBs.
7.3 Other Hazardous Building Materials
Household hazardous waste was collected throughout the property and stored in the outbuilding. We recommend
that the City of Edmonds should coordinate with Snohomish County to drop off the waste at one of their household
hazardous waste collection locations.
Z WAC 296-155-17607 (1): You must ensure that no employee is exposed to lead at concentrations greater than 50
micrograms per cubic meter of air (50 µg/m3) averaged over an 8-hour period.

8.0 LIMITATIONS
This report presents the results of the hazardous building materials assessment conducted for the City of Edmonds
at 9309 Bowdoin Way in Edmonds, WA. The assessment was conducted with the objective of identifying hazardous
building materials in anticipation of demolition in accordance with certain regulations requiring such identification.
For example, 40 CFR 763, along with Puget Sound Clean Air Agency Regulation III, Article 4.02(a), requires an
"Asbestos Survey" before the renovation or demolition of a building. In addition, the Washington State Dangerous
Waste Regulations (WAC 173-303) requires identification and designation of solid waste prior to disposal. This
includes suspect lead -based paint and building materials.
Our assessment has considered risks pertaining to asbestos, lead in paint, polychlorinated biphenyls universal
waste, and other hazardous building materials discussed in Section 6 of this document. Our assessment is limited
to only those locations and materials assessed. This assessment was not designed to identify all potential concerns
or to eliminate all risks associated with renovation, demolition, construction, waste disposal, or transferring of
property title. Evaluation of other risks not specifically described in the Scope of Work have not been included. For
example, the following risks were not assessed: structural integrity, engineering loads, electrical, mechanical, radon
gas, slope stability, building settlement, and evaluation of toxic and hazardous substances in, or in contact with, soil
and groundwater. No warranty, expressed or implied, is made. DH Environmental has performed the services set
forth in the Scope of Work in accordance with generally accepted practices in the same or similar localities, related
to the nature of the work accomplished, at the time the services were performed.
The hazardous building materials assessment presented in this report represents the conditions and materials
observed on the dates we conducted the sampling and visually inspected the building. This assessment report is
intended for the exclusive use of the City of Edmonds for specific application to the referenced property. This
assessment does not replace or should be used in lieu of professionally developed construction or demolition plans,
specifications, or bidding documents. This report is not a legal opinion.

RE: Bulk Asbestos Fiber Analysis; NVL Batch # 2307219.00
Client Project: 9309
Location: City of Edmonds
Dear Mr. Johnson,
NVL
INDUSTRIAL HYGIENE SERVICES
LABORATORY I MANAGEMENT - TRAINING
Enclosed please find test results for the 19 sample(s) submitted to our laboratory for analysis on
5/4/2023.
Examination of these samples was conducted for the presence of identifiable asbestos fibers using
polarized light microscopy (PLM) with dispersion staining in accordance with U. S. EPA 40 CFR
Appendix E to Subpart E of Part 763, Interim Method for the Determination of Asbestos in Bulk
Insulation Samples and EPA 600/R-93/116, Method for the Determination of Asbestos in Bulk Building
Materials.
For samples containing more than one separable layer of materials, the report will include findings for
each layer (labeled Layer 1 and Layer 2, etc. for each individual layer). The asbestos concentration in
the sample is determined by calibrated visual estimation.
For those samples with asbestos concentrations between 1 and 10 percent based on visual estimation,
the EPA recommends a procedure known as point counting (NESHAPS, 40 CFR Part 61). Point
counting is a statistically more accurate means of quantification for samples with low concentrations of
asbestos.
The detection limit for the calibrated visual estimation is <1 %, 400 point counts is 0.25% and 1000 point
counts is 0.1 %
Samples are archived for two weeks following analysis. Samples that are not retrieved by the client are
discarded after two weeks.
Thank you for using our laboratory services. Please do not hesitate to call if there is anything further we
can assist you with.
Sincerely,
Nick Ly, Technical Director
