1.0 INTRODUCTION
Ecocon, Inc (ECI) has completed the arsenic and lead investigation for the property known as: King County
Parcels: 042104-9012 & 042104-9221 which is located at the intersection of Pacific Highway/WA-99 &
South 304th Street in Federal Way, Washington (Property/ Subject Property) (Figure 1, Appendix A).
The purpose of this investigation was to identify and delineate potential arsenic and lead contamination
the guidance of the Department of Ecology (Ecology) concerning arsenic (As) and lead (Pb) resulting from
the former Asarco Tacoma Smelter Site (Ecology Publication number 12-09-086).
1.1 Subject Property Location / Description
The Subject Property is located at the intersection of Pacific Highway/WA-99 & South 304th Street in
Federal Way, Washington (King County parcel numbers 042104-9012 & 042104-9221) and is bounded by:
• SmartCare Daycare and Residential housing to the north;
• Pacific Highway/WA-99 to the west;
• South 304th St to the south; and
• Residential neighborhoods to the east.
The greater vicinity is occupied by primarily residential developments. According to research conducted
by ECI, the Subject Property falls into the Moderate Zone (20-100ppm As/Pb) of contamination produced
by the Asarco Tacoma Smelter.
1.2 Previous Environmental Investigations and Remedial Actions
1.2.1 Arsenic & Lead Soil Screening – Ecocon, Inc – April,2019
In April 2019 ECI mobilized to the Subject Property and completed a limited environmental screening
focused on potential As and Pb impacted soils. This investigation was conducted as a screening only and
was not in accordance with Ecology Remedies Guidance “Sampling & Cleanup of Arsenic & Lead
Contaminated Soils, Publication 12-09-086.
Ten sample locations were selected, and a total of 14 samples were collected which included 10 surface
soil samples collected between 0 to 6” below ground surface (bgs), and 4 samples of forest duff (the leaves
and decomposing matter which rests on the forest floor). Samples were analyzed by Friedman & Bruya of
Seattle, Washington. Of the samples analyzed, none were above MTCA method A Cleanup levels (CULs)
for As (CUL = 20 ppm) or Pb (CUL = 250 ppm). However, the analytical results revealed that each of the
samples contained concentrations below the cleanup level of both As and Pb.
1.4 Regulatory Compliance and Cleanup Standards
Regulatory compliance for this project is based on the Washington Administrative Code (WAC) 173-340 –
Model Toxic Control Act (MTCA) - RCW Chapter 70.105D, implemented by the Washington State
Department of Ecology. Pursuant to Chapter 70.105D RCW, Ecology has established cleanup standards
and requirements for cleanup actions. The rules establishing these standards and requirements were
developed by Ecology in consultation with the Science Advisory Board (established under the Act) and

with representatives from local government, citizen, environmental, and business groups. The rules were
first published in February 1991, with amendments in January 1996, February 2001, and October 2007.
Sampling procedures and sampling requirements are detailed in the Ecology publications 12-09-086
(Asarco Tacoma Smelter Site Final Interim Action Plan for the Tacoma Smelter Plume) and 12-09-086A
(Tacoma Smelter Plume Model Remedies Guidance - Sampling and cleanup of arsenic and lead
contaminated soils).
The COCs and the respective CULs are shown in the table below:

2.0 SAMPLE COLLECTION
2.1 Pre-Sample Collection Activities
Sampling activities were completed as outlined in Ecology guidance 12-09-086A. This guidance document
recommends the following steps to determine the number and location of samples needed:
• Characterize the Site,
• Divide the Site into decision units,
• Choose the number of samples based on the chart provided (Table 3 in Section 2.1.3),
• Determine sample locations, and
• Determine sample depths
2.1.1 Site Characterization
The Subject Property is currently forested, but the intended use of the Property is development into
multifamily residential. The intended use of the Property means that the number of sample locations will
be based on “Residential, Parks, Commercial”.
2.1.2 Decision Units
A decision unit is an area of a property expected to have a different pattern of soil contamination than
other areas. It may also be defined as an area of the property with a different use (such as open land and
playgrounds). At this time, ECI has not been made aware of any special areas set aside for playgrounds,

gardens, unforested land, or graded areas of the Property which may have triggered the need for
additional decision units. For this Property, only one decision unit is required.
2.1.3 Number of Samples
The number of samples required by Ecology is based on the size of a decision unit and the intended land
use of the property. The table below details the number of sample locations required according to the
size and use of a property:
Table 2: Minimum Number of Sample Locations per Decision Unit
Sampling Area Residential, Parks, Commercial
Samples needed Forest and Open land samples needed
Acres Arsenic >100 ppm Arsenic 20-100
ppm Arsenic >100 ppm Arsenic 20-100

>100 120 + 1 per 5
acres 90 + 1 per 5 acres 70 + 1 per 10
acres
60 + 1 per 10
acres
Because the intended use of the Property is residential, the size of the decision unit (entire Property) is
closest to 20 acres in size, and the Property has been identified by Ecology as within the 20-100 ppm area,
the number of sample locations required is 64. For each decision unit, an additional 25% of samples are
required at depths between 6 and 12 inches. Because forest duff is present at the Subject Property, six
forest duff samples are also required, which can be analyzed as a single composite sample. ECI previously
collected 10 soil samples from 10 discrete locations which may be used to offset the number needed for
completion of the current investigation.
The total number of samples collected from the remaining 54 required sample locations was 70 (69
discreet samples and 1 forest duff composite sample).
2.1.4 Sample Locations
Sample locations were laid out in a grid evenly spaced throughout the Property. Each grid was
approximately 120 ft x 120 ft in length or 14,700 sq ft. Grid layout and sample locations are presented in
Figure 3 in Appendix A.
2.2 Sample Collection
On June 11th and 12th, 2019, ECI environmental professionals mobilized to the site and collected a total of
69 soil samples and 6 forest duff samples. Samples were collected using properly decontaminated
stainless steel sampling equipment and transferred into clean resealable sample bags. Forest duff samples
were collected in six locations and combined into a composite sample. New nitrile gloves were used during

sample collection and changed between samples tand sampling equipment was decontaminated using a
mixture of deionized water and tri-sodium phosphate (TSOP) to reduce the possibility of cross-
contamination. Samples were transferred under industry standard chain of custody protocol to Friedman
& Bruya of Seattle, Washington on June 13th, 2019.
Sample locations and quantity were determined based on Ecology Guidance Document 12-09-086A.
Sample locations and grid layout are presented in Figure 3, Appendix A.
3.0 LABORATORY ANALYSIS
Soil samples were analyzed for total arsenic and total lead by EPA Method 200.8 and 6020B respectively.
Analytical results of sample F8-0-6” revealed a result above the maximum 40 mg/kg arsenic. None of the
samples exceed the maximum concentration of 500 mg/kg lead cleanup level. The average arsenic and
lead were 14.1 and 41.4 respectively, below the 20 mg/kg arsenic and 250 mg/kg lead cleanup levels.
Sample results are detailed in Table 3 below:

4.0 SUMMARY AND RECCOMENDATIONS
4.1 Summary
On June 11th and June 12th, 2019 ECI professionals collected a total of 69 soil samples and one forest duff
sample from the Subject Property. The purpose of this sampling event was to fulfill testing requirements
set forth in Ecology Publication 12-09-086A which concerns areas affected by the Tacoma Smelter Plume.
The results of the analysis performed on the samples indicates that the average concentrations for Pb and
As for the Subject Property are below the concentration indicated by 12-09-086A which would trigger a
cleanup action. However, one sample (F8-0-6”) was found to be above the maximum allowed
concentration for a discreet soil sample for As, which triggers a cleanup in that area of the Subject
property.
4.2 Recommendations
Based on the results of this investigation, further action is necessary in the area with elevated levels of
arsenic and/or lead (grid area F8). Ecology’s guidance provides two permanent remediation options for
sites with elevated lead and/or arsenic concentrations. They are: 1) Excavation and Removal and 2) Soil
Mixing. Depending on the grade and fill specifications for the planned development, mixing may be the
most appropriate and cost-effective option. Details regarding how this remedy should be implemented
are provided in excerpts from the Ecology Guidance Publication in the tables below:

ECI recommends the Subject Property be entered into the Ecology Voluntary Cleanup Program (VCP). This
process will provide Ecology with the necessary information to provide a No Further Action determination
following corrective actions. Grid area F8, measuring approximately 50 feet by 50 feet or approximately
2500 square feet. In order to move forward with corrective action, a work plan will need to be developed
and reviewed by Ecology. This is typically competed as port of the VCP process. Once approved, corrective
action can be competed. This process is expected to take between 60 and 90 days. Should the corrective
action work move forward, a Project Schedule of Values will be prepared. Corrective action costs are
anticipated to range between $20,000 and $30,000. This cost estimate dependent on the depth of
excavation and confirmation (post remediation) sample results.
ECI appreciates the opportunity to provide environmental consulting services on this project. Should you
have any questions, please contact our office at (253) 238-9270.
5.0 QUALIFICATIONS OF THIS REPORT
Some clients, design professionals and contractors may not recognize that the geoscience practices
(geotechnical engineering, geology, and environmental science) are far less exact than other engineering
and natural science disciplines. This lack of understanding can create unrealistic expectations that could
lead to disappointments, claims and disputes. EcoCon Inc. includes these explanatory “limitations”
provisions in our reports to help reduce such risks. Please confer with EcoCon if you are unclear how these
“Report Limitations and Guidelines for Use” apply to your project or Site.
5.1 Use of this Report by Others
Our report was prepared for the exclusive use of American Classic Homes and designated agent/ensigns.
This report may be provided to regulatory agencies for review if requested or required. No other party
may rely on the product of our services unless we agree in advance to such reliance in writing. This is to
provide our firm with reasonable protection against open-ended liability claims by third parties with
whom there would otherwise be no contractual limits to their actions. Within the limitations of scope,
schedule and budget, our services have been executed in accordance with our Agreement with
Exhibit 17

Porters/ARS and generally accepted environmental practices in this area at the time this report was
prepared.
This report has been prepared for subsurface investigation activities at the Subject Property. EcoCon
considered a number of unique, project-specific factors when establishing the scope of services for this
project and report. No one except Porters/ARS and designated agent/ensigns should rely on this
environmental report without first conferring with ECI. This report should not be applied for any purpose
or project except the one originally contemplated.
Unless EcoCon specifically indicates otherwise, do not rely on this report if it was:
• Not prepared for you,
• Not prepared for your project,
• Not prepared for the specific site explored, or
• Completed before important site changes were made.
If important changes are made after the date of this report, EcoCon Inc. should be given the opportunity
to review our interpretations and recommendations and provide written modifications or confirmation,
as appropriate.
5.2 Uncertainty May Remain after Completion of Site Investigation and Remedial Activities
The investigation and remediation activities completed in a portion of a site cannot wholly eliminate
uncertainty regarding the potential for contamination in connection with the entire property. Our
interpretation of subsurface conditions in this study is based on field observations and chemical analytical
data from the locations sampled. It is always possible that contamination exists in areas that were not
explored, sampled, or analyzed.
5.3 Subsurface Conditions Can Change
This environmental report is based on conditions that existed at the time the study was performed. The
findings and conclusions of this report may be affected by the passage of time, by manmade events such
as construction on or adjacent to the Site, by new releases of hazardous substances, or by natural events
such as floods, earthquakes, slope instability or groundwater fluctuations. Always contact EcoCon before
applying this report to determine if it is still applicable.
5.4 Soil and Groundwater End Use
The cleanup levels referenced in this report are Site- and situation-specific and could change with time
due to regulatory or Site changes. The cleanup levels may not be applicable for other sites or for other on-
site uses of the affected media (soil and/or groundwater).
Note that hazardous substances may be present in some of the Site soil and/or groundwater at detectable
concentrations that are less than the referenced cleanup levels. Because these cleanup levels can change,
EcoCon should be contacted to evaluate the potential for associated environmental liabilities prior to the
export of soil or groundwater from the Subject Site or reuse of the affected media on the Site. We cannot
be responsible for potential environmental liability arising out of the transfer of soil and/or groundwater
from the Subject Site to another location or its reuse on the Site in instances that we were not aware of
or could not control.

5.5 Most Environmental Findings Are Professional Opinions
Our interpretations of subsurface conditions are based on field observations and chemical analytical data
from the locations sampled at the Site. Site exploration identifies subsurface conditions only at those
points where subsurface tests are conducted, or samples are taken. EcoCon Inc. reviewed field and
laboratory data and then applied our professional judgment to render an opinion about subsurface
conditions throughout the Site. Actual subsurface conditions may differ – sometimes significantly – from
those indicated in this report. Our report, conclusions and interpretations should not be construed as a
warranty of the subsurface conditions.

Data Qualifiers & Definitions a - The analyte was detected at a level less than five times the reporting limit. The RPD results may not provide reliable information on the variability of the analysis.
b - The analyte was spiked at a level that was less than five times that present in the sample. Matrix spike recoveries may not be meaningful.
ca - The calibration results for the analyte were outside of acceptance criteria. The value reported is an estimate.
c - The presence of the analyte may be due to carryover from previous sample injections.
cf - The sample was centrifuged prior to analysis.
d - The sample was diluted. Detection limits were raised and surrogate recoveries may not be meaningful.
dv - Insufficient sample volume was available to achieve normal reporting limits.
f - The sample was laboratory filtered prior to analysis.
fb - The analyte was detected in the method blank.
fc - The analyte is a common laboratory and field contaminant.
hr - The sample and duplicate were reextracted and reanalyzed. RPD results were still outside of control limits. Variability is attributed to sample inhomogeneity.
hs - Headspace was present in the container used for analysis.
ht – The analysis was performed outside the method or client-specified holding time requirement.
ip - Recovery fell outside of control limits due to sample matrix effects.
j - The analyte concentration is reported below the lowest calibration standard. The value reported is an estimate.
J - The internal standard associated with the analyte is out of control limits. The reported concentration is an estimate.
jl - The laboratory control sample(s) percent recovery and/or RPD were out of control limits. The reported concentration should be considered an estimate. js - The surrogate associated with the analyte is out of control limits. The reported concentration should be considered an estimate.
lc - The presence of the analyte is likely due to laboratory contamination.
L - The reported concentration was generated from a library search.
nm - The analyte was not detected in one or more of the duplicate analyses. Therefore, calculation of the RPD is not applicable.
pc - The sample was received with incorrect preservation or in a container not approved by the method. The value reported should be considered an estimate. ve - The analyte response exceeded the valid instrument calibration range. The value reported is an estimate.
vo - The value reported fell outside the control limits established for this analyte.
x - The sample chromatographic pattern does not resemble the fuel standard used for quantitation.

Data Qualifiers & Definitions a - The analyte was detected at a level less than five times the reporting limit. The RPD results may not provide reliable information on the variability of the analysis.
b - The analyte was spiked at a level that was less than five times that present in the sample. Matrix spike recoveries may not be meaningful.
ca - The calibration results for the analyte were outside of acceptance criteria. The value reported is an estimate.
c - The presence of the analyte may be due to carryover from previous sample injections.
cf - The sample was centrifuged prior to analysis.
d - The sample was diluted. Detection limits were raised and surrogate recoveries may not be meaningful.
dv - Insufficient sample volume was available to achieve normal reporting limits.
f - The sample was laboratory filtered prior to analysis.
fb - The analyte was detected in the method blank.
fc - The analyte is a common laboratory and field contaminant.
hr - The sample and duplicate were reextracted and reanalyzed. RPD results were still outside of control limits. Variability is attributed to sample inhomogeneity.
hs - Headspace was present in the container used for analysis.
ht – The analysis was performed outside the method or client-specified holding time requirement.
ip - Recovery fell outside of control limits due to sample matrix effects.
j - The analyte concentration is reported below the lowest calibration standard. The value reported is an estimate.
J - The internal standard associated with the analyte is out of control limits. The reported concentration is an estimate.
jl - The laboratory control sample(s) percent recovery and/or RPD were out of control limits. The reported concentration should be considered an estimate. js - The surrogate associated with the analyte is out of control limits. The reported concentration should be considered an estimate.
lc - The presence of the analyte is likely due to laboratory contamination.
L - The reported concentration was generated from a library search.
nm - The analyte was not detected in one or more of the duplicate analyses. Therefore, calculation of the RPD is not applicable.
pc - The sample was received with incorrect preservation or in a container not approved by the method. The value reported should be considered an estimate. ve - The analyte response exceeded the valid instrument calibration range. The value reported is an estimate.
vo - The value reported fell outside the control limits established for this analyte.
x - The sample chromatographic pattern does not resemble the fuel standard used for quantitation.
