Survey Summary
On January 28, 2020, Kimberly Riche and Jason Carlson of Med-Tox Northwest
(MTNW) conducted a hazardous building materials (HBM) survey of Lakehaven
Administrative Building located at 31531 1st Avenue South, in Federal Way,
Washington. The survey included asbestos, lead, heavy metals, and polychlorinated
biphenyls (PCB). The building was unoccupied during the survey. There were
limitations on the destructive nature of the survey investigation.
This survey consisted of a visual inspection, touching of suspect materials and sample
collection with analysis. No previous HBM surveys were available as part of the survey.
As required by Washington Administrative Code (WAC) 296-62-077 and Puget Sound
Clean Air Agency (PSCAA), building inspectors certified under the Asbestos Hazard
Emergency Response Act (AHERA) and employed by MTNW conducted the asbestos
portion of the survey. A copy of the inspectors’ AHERA building inspector and
Washington Department of Commerce (WDOC) Lead Risk Assessor certificates are
included in Appendix A.
Building Information
General and Structural
Lakehaven Center Building (modular) building is one-story structure that is
approximately 2,160 square feet in size. The building was originally constructed in
1985.
The interior of the building includes offices, conference rooms, bathrooms, electrical
room, server room, and storage room.
Heating and Mechanical:
Heating is provided by forced air heating, ventilation, and air conditioning (HVAC) with
duct work throughout the ceiling. The HVAC ducts for the heating system are insulated
with foil, mastic, and yellow fiberglass insulation. The pipes that were observed were
un-insulated. There was no access to the crawl space at the time of the survey.
Walls/ceiling
The walls consist of wallpaper, untextured (GWB) gypsum wall board system, and wall
panels. The ceilings consist of acoustical ceiling tiles (ACT).
Hazardous Building Materials Survey — Lakehaven Center Building
February 2020 2 Helix Design Group, Inc.
Flooring Systems:
There are multiple flooring types observed to be affixed to the wood substate. These
flooring materials include sheet vinyl flooring (SVF) and carpet.
Asbestos Summary
The AHERA regulation, 40 Code of Federal Regulations (CFR) 763, is the primary
governing regulation when performing asbestos surveys. This regulation was originally
enacted for school buildings but has since been applied to public and commercial
buildings by the Asbestos School Hazard Abatement Reauthorization Act (ASHARA) in
1994 and by the Occupational Safety and Health Administration’s (OSHA) worker
protection regulations in 1995, specifically 29 CFR 1926.1101(k).
PSCAA also requires compliance with AHERA’s survey and sampling requirements.
This applies to any renovation or demolition activities where suspect asbestos-
containing material (ACM) may be disturbed. PSCAA is a local agency that receives
statutory authority from the Environmental Protection Agency (EPA) to enforce
environmental regulations.
AHERA divides suspect ACM into three categories; “surfacing materials” (i.e., sprayed
fireproofing, popcorn ceiling texture, etc.), “thermal system insulation” (TSI) (i.e., pipe or
building insulation, etc.), and “miscellaneous materials” (i.e., flooring material, roofing,
construction mastics, etc.). For a complete listing of suspect materials sampled, see
Appendix B.
Sampling locations are indicated on the drawing in Appendix D. Table 1 below lists
asbestos-containing materials identified as part of this survey.

Lead-Based Paint Summary
Lead was commonly used in most paint products until 1978, when it was banned from
residential paints at concentrations greater than 600 parts per million (ppm); however,
commercial applications with lead are still utilized and available. Lead is poisonous to
the human body and presents a potential health hazard during any kind of disturbance
(such as maintenance, including grinding, welding, and cutting) and if improperly
disposed, where lead can enter drinking water supplies.
EPA defines lead-based paint (LBP) as a concentration of 1.0 milligrams per centimeter
squared (mg/cm2) or greater by x-ray fluorescence (XRF) or 0.5 percent by weight (%
wt.) or greater by total lead analysis; equivalent to 5,000 milligrams per kilogram
(mg/kg). This EPA action level triggers requirements for protection of the environment,
Hazardous Building Materials Survey — Lakehaven Center Building

maintenance workers, and building occupants in child occupied facilities as defined by
40 CFR 745. Additionally, building components exceeding EPA lead levels may cause
demolition waste streams to fail waste designation sampling performed for compliance
with WAC 173-303 Dangerous Waste Regulations.
Washington Industrial Safety and Health Act (WISHA) worker protection regulations
have not defined a minimum concentration for regulating lead and has clarified that lead
at any detectable concentration shall be considered regulated by WAC 296-155-176,
Lead. Paint sample results can be expressed in mg/kg (same as ppm), % wt. or
mg/cm2 by area depending on the type of analytical method used. Any positive result,
regardless of the reporting method by the laboratory, will require compliance with WAC
296-155-176.
Lead in Painted Surfaces
Interior and exterior painted surfaces were collected and analyzed for LBP using bulk
sample collection and chemical analysis. A total of four paint chip samples were
collected. Analytical results are provided in Table 3.

GWB = gypsum wallboard, % wt. = percent by weight.
Waste Designation Survey
Waste designation sampling has been performed for the building demolition, including
Toxicity Characterization Leaching Procedure (TCLP) analytical sampling of affected
building components. The TCLP procedure is used to simulate the transfer of lead from
lead-containing waste into the ground water system upon co-disposal of the lead-
containing waste and municipal solid waste in unlined solid waste landfills. The TCLP
attempts to simulate rain or ground water leaching, or both, of lead from the buried
waste. In order for the procedure to yield an accurate predictor of the subsurface (in-
ground) leaching process, a representative sample of the volume of the waste must be
selected and submitted for leaching and analysis. The result of the sampling, leaching,
and analysis process is used to determine the waste handling and disposal protocols to
be followed and to document compliance with applicable laws, regulations, and
requirements. WAC 173-303 Dangerous Waste Regulations defines hazardous waste
as it relates to lead by toxicity as 5.0 milligrams per Liter (mg/L) by TCLP.
Hazardous Building Materials Survey — Lakehaven Center Building
February 2020 7 Helix Design Group, Inc.
A visual inspection of the survey area was conducted to separate the major components
of the structures to be demolished into the following categories:
•Recyclables. It is anticipated that many of the metal items (i.e., metal
piping, tanks, door frames, doors, handrails, flashing, aluminum window
frames, etc.) and un-painted clean concrete materials in the survey area
will be recycled or reused. These items were not tested for waste pre-
designation. Additionally, glass is recyclable and not included in the waste
designation survey.
•Potential Wastes. Items that are not likely to be recycled were sampled
and tested for waste pre-designation. Samples of other building finish
materials likely to be landfill disposed were collected, composited and
submitted for TCLP testing.
•Assumed hazardous waste. None.
The sample tested for waste designation did not include metal, glass or concrete.
One composited sample was collected from the site and tested by TCLP analysis for
Resource Conservation and Recovery Act (RCRA) metals – Arsenic, Barium, Cadmium,
Chromium, Lead, Selenium, Silver and Mercury. The result for the sample is presented
in Table 4:

The TCLP sample collected from the Lakehaven Center Building was determined to
have leachable heavy metals less than the regulated levels for the RCRA 8 metals.
Demolition waste from this structure can be disposed of as general construction debris.
WAC 173-303 Dangerous Waste Regulations defines hazardous waste as it relates to
heavy metal by toxicity. The following identifies the regulatory limits for the tested
heavy metals.

Other Hazardous Building Materials
Chlorofluorocarbons
MTNW inspected the building for cooling systems with potential chlorofluorocarbons
(CFCs); there were no CFCs observed.
PCB Light Ballasts and Fluorescent Light Tubes
Older fluorescent light ballasts have small capacitors that may contain high
concentrations of PCBs. Nearly all ballasts manufactured before 1979 contain PCBs.
All ballasts manufactured after July 1, 1978 that do not contain PCBs are required to be
clearly marked "No PCBs". Unmarked ballasts or ballasts without a date code should
be assumed to be PCB ballasts. PCBs are toxic chemicals according to the EPA.
While there is only a small amount, about one ounce, of PCBs in each light ballast
capacitor, there are a large number of ballasts in the United States. A "No PCB" label
means there are less than 50 ppm PCBs however, in the state of Washington PCB in
oils are regulated at 2 ppm (WAC 173-303-9904). Ballasts manufactured after 1978/79
may contain a PCB replacement called Di (2-ethylhexyl) phthalate (DEHP), a probable
human carcinogen. DEHP, a clear, odorless, synthetic compound, is often used as a
plasticizer. By 1985, most manufacturers had stopped using DEHP in ballasts for 4-foot
fixtures but continued to use it for most 8-foot and high intensity discharge fixtures until
1991. In any case, ballasts should not be disassembled for disposal but collected and
sent to a treatment, storage or disposal facility certified by the state/EPA for disposal of
PCBs and/or DEHP.
There were fluorescent light fixtures observed. Table 5 provides a summary of these
items in the building:

Note: This table is not to be used without the complete survey document including appendices for additional
information.
Typically, there is one ballast for every two-light tubes in a fluorescent light fixture;
accordingly, there are 20 ballasts in the light fixtures requiring recycling or PCB
hazardous waste disposal. There are also 40 light tubes and 2 exit signs that will need
to be recycled during demolition.
PCB in Caulking and Paint
PCBs were used in paint and caulk formulations as drying oils (resins) and plasticizers
or softening agents (liquids). Wood, concrete, gypsum wallboard and metal may have
painted surfaces containing PCBs.
PCBs were tested in representative paints and caulking from the interior and exterior of
the building. Table 6 below provides a summary of PCB sample results.

Laboratory Analytical Methods
Asbestos-Containing Materials
Bulk samples were analyzed by Polarized Light Microscopy (PLM) dispersion staining
EPA Method 600/R-93/116 by Seattle Asbestos Test (SAT). SAT is accredited through
the National Voluntary Laboratory Accreditation Program (NVLAP) of the U. S.
Department of Commerce. This accreditation does not constitute endorsement, but
rather a finding of laboratory competence. The NVLAP participant number is 200768-0
(certification in Appendix E). Copies of the laboratory analytical reports are provided in
Appendix F.
Lead-Based Paint
Bulk paint chip samples were submitted to EMSL Analytical, Inc. (EMSL) for analysis
using atomic absorption spectroscopy (AAS) to determine the presence and percentage
of lead. Procedures for analyzing metals are found in the American Society of Testing
and Materials (ASTM) D-3335-78 and EPA Method Manual SW-846, Method 6010.
EMSL used SW 846-7000B, an equivalent analytical method.
Analytical results for paint chips are provided in Appendix G. EMSL’s laboratory
certification is attached in Appendix H.
PCBs
Bulk PCB samples were submitted to On-Site Environmental, Inc., for analysis using
gas chromatography (GC) equipped with electron capture detectors (ECD). Samples
were analyzed using EPA Method SW-846 8082A. Analytical results are provided in
Appendix H. On-Site Environmental, Inc. laboratory certification is attached in

Comments and Recommendations
Asbestos-Containing Materials
MTNW recommends, and state law requires, that all asbestos materials identified in
Table 1 that will be impacted be removed prior to renovation or demolition activities.
Med-Tox Northwest recommends that this survey report be placed on-site during
renovation and/or selective demolition and copies provided to the contractor(s) bidding
and performing work. WISHA, OSHA and PSCAA require that the report be on-site and
available for review during the entire project duration.
Lakehaven Center Building was occupied at the time of the survey and destructive
investigation was not conducted at the request of the client. Additional destructive
investigation will be required prior to demolition.
1.Electrical systems were not sampled due to power being live. Prior to any
activity that will impact the electrical system, sample and verify that asbestos is
not present in wiring.
2.All pipes observed were bare of insulation, so it is not anticipated that hidden
pipes will be insulated. During the course of demolition, if pipe or pipe fitting
insulation suspected of containing ACM is made visible, the material must be
sampled by an AHERA building inspector prior to being disturbed.
3. The building doors and door frames were not sampled due to voiding the fire
rating. Prior to any activity that will impact the doors, sample the doors and door
frames to determine if suspect fire protection is located inside.
4.There was no access to the crawl space at the time of the survey.
Med-Tox Northwest recommends requesting unit pricing from abatement contractors
during the bidding process to adjust pricing depending on actual quantities verified in
the field.
Lead-Based Paint
For lead, any percentage of lead in the material should be an assumed risk to human
health. All painted surfaces should be assumed to contain at least trace levels of lead
in paint, therefore requiring compliance with WAC 296-155-176 during any disturbance
Hazardous Building Materials Survey — Lakehaven Center Building
February 2020 12 Helix Design Group, Inc.
of painted surfaces. The WISHA criteria are used to determine if materials are
hazardous during a demolition.
There were four bulk samples collected for lead analysis. All of the samples analyzed
were determined to have less than the detection limit for lead.
The TCLP sample collected from the Lakehaven Center Building was determined to
have leachable heavy metals less than the regulated levels for the RCRA 8 metals.
Demolition waste from this structure can be disposed of as general construction debris.
PCB
During demolition, the asbestos abatement contractor should be tasked with dismantling
light fixtures, checking for PCB-free labels, and recycling the light tubes. Ballasts
without PCB-free labels are considered PCB-containing and must be disposed as a
hazardous waste; all other light ballasts can be recycled. Additionally, light tubes can
be recycled as a universal waste for minimal cost.
Other Hazardous Building Materials
Fluorescent light tubes contain mercury and can be recycled as a universal waste for
minimal cost. Lighted exit signs with emergency lights should be collected and
recycled/disposed of appropriately.

Limitations
A good faith effort has been made to identify ACM, LBP, and other HBM in preparation
for the renovation or building demolition at Lakehaven Center Building. The building
was unoccupied during the survey, additional destructive investigation and sampling
may be required depending on inaccessible building systems.
Sampling was performed consistent with the level of care and skill ordinarily exercised
by professionals currently practicing under similar conditions in the area. No other
warranty, expressed or implied, is made.

This report pertains to the samples analyzed in accordance with the chain of custody,
and is intended only for the use of the individual or company to whom it is addressed.
Data Qualifiers and Abbreviations A - Due to a high sample concentration, the amount spiked is insufficient for meaningful MS/MSD recovery data. B - The analyte indicated was also found in the blank sample. C - The duplicate RPD is outside control limits due to high result variability when analyte concentrations are within five times the quantitation limit. E - The value reported exceeds the quantitation range and is an estimate. F - Surrogate recovery data is not available due to the high concentration of coeluting target compounds. H - The analyte indicated is a common laboratory solvent and may have been introduced during sample preparation, and be impacting the sample result. I - Compound recovery is outside of the control limits. J - The value reported was below the practical quantitation limit. The value is an estimate. K - Sample duplicate RPD is outside control limits due to sample inhomogeneity. The sample was re-extracted and re-analyzed with similar results. L - The RPD is outside of the control limits. M - Hydrocarbons in the gasoline range are impacting the diesel range result. M1 - Hydrocarbons in the gasoline range (toluene-naphthalene) are present in the sample. N - Hydrocarbons in the lube oil range are impacting the diesel range result. N1 - Hydrocarbons in diesel range are impacting lube oil range results. O - Hydrocarbons indicative of heavier fuels are present in the sample and are impacting the gasoline result. P - The RPD of the detected concentrations between the two columns is greater than 40. Q - Surrogate recovery is outside of the control limits. S - Surrogate recovery data is not available due to the necessary dilution of the sample. T - The sample chromatogram is not similar to a typical ____________. U - The analyte was analyzed for, but was not detected above the reported sample quantitation limit. U1 - The practical quantitation limit is elevated due to interferences present in the sample. V - Matrix Spike/Matrix Spike Duplicate recoveries are outside control limits due to matrix effects. W - Matrix Spike/Matrix Spike Duplicate RPD are outside control limits due to matrix effects. X - Sample extract treated with a mercury cleanup procedure.
X1- Sample extract treated with a sulfuric acid/silica gel cleanup procedure.
Y - The calibration verification for this analyte exceeded the 20% drift specified in methods 8260 & 8270, and
therefore the reported result should be considered an estimate. The overall performance of the calibration
verification standard met the acceptance criteria of the method. Z - ND - Not Detected at PQL
PQL - Practical Quantitation Limit
