1.0 INTRODUCTION 1.1 Subject Property Description
The subject property is located at 1200 Lake Washington Boulevard North in Renton, King County, Washington (Figure 1). The subject property consists of tax parcel numbers 334450-0006 and 082305-9056 with a reported total area of approximately 2.86 acres (see Figure 2). The subject property is currently being developed with a 5-story Marriott Residence Inn hotel. 1.2 Subject Property Background / Prior Environmental Assessments Phase I Environmental Site Assessment (Adapt, April 2014) Adapt prepared a Phase I Environmental Site Assessment (ESA) for the subject property in April 2014. The Phase I ESA indicated that a historic gasoline station was located along the western portion of the subject property from approximately 1920 through the 1950s/1960s. The operational end date for the historic gasoline was not determined based on the historical information that was readily available. The reviewed archived King County tax assessment
records included a photograph of the historic gasoline station and a diagram of the layout of the
station (see Appendix B and Figure 3).
Limited Phase II Screen (Adapt, April 2014)
Adapt conducted a Limited Phase II Screen in the inferred area of a historical gas station
located on the subject property. This screen included a survey around the area by Ground
Penetrating Radar (GPR) to potentially discover relic USTs or other pertinent subsurface
features. One “GPR anomaly” was revealed. Using a Geoprobe, five borings were advanced
around this anomaly, especially to the west, northwest, and south (see Figure 4). The
maximum depth explored was approximately 10 feet below ground surface (bgs). Groundwater
grab samples were collected in three of the borings, and submitted to the analytical laboratory
for analysis for gasoline, diesel, and heavy oil range total petroleum hydrocarbons, benzene, toluene, ethylbenzene, xylenes (BTEX), and lead. The groundwater sample from only one of the borings exhibited TPH concentrations above laboratory reporting limits. In particular, this exhibited: gasoline-range TPH at 160 parts per billion (ppb), below the pertinent State of Washington Department of Ecology Model Toxics Control Act (MTCA) Method A Soil Cleanup Level for Unrestricted Land Uses (CUL) of 1,000 ppb (with no lead detected); diesel-range TPH at 120 ppb, below the Method A cleanup level of 500 ppb (this result was flagged as not representing the fuel standard used for quantitation); and ethylbenzene at a concentration of 2.5 ppb, well below the Method A CUL of 700 ppb. UST Subsurface Assessment (Adapt, September 2014) On September 22, 2014, Langseth Environmental Services (Langseth) provided the necessary
excavation equipment and personnel to complete test pit excavations in the location of the
inferred UST-like GPR anomaly identified during the Limited Phase II Screen previously
completed by Adapt. One (1) gasoline UST was encountered at a depth of approximately 3 feet
below ground surface (bgs) in the immediate vicinity of the UST-like GPR anomaly. The
gasoline UST was approximately 92 inches in length and approximately 38 inches in diameter
(approximately 450 gallons). Three (3) soil samples were collected from possible contaminated
soils encountered during the excavation activities. The analytical results for the three (3) soil
samples collected indicated detected concentrations for the following compounds: gasoline
range TPH varied from 3 to 1,400 parts-per-million (ppm); benzene varied from 1.1 to 2.3 ppm,

toluene varied from 4.7 to 15 ppm; ethylbenzene varied from 3.1 to 11 ppm; total xylenes varied
from 0.075 to 62 ppm; and lead varied from 4.39 to 60.6 ppm (see Table 1).
UST Removal / Site Assessment (Adapt, September 2014) The UST decommissioning and removal work was completed on October 16, 2014. Adapt determined that a UST of approximately 450 gallon capacity was present on the subject property, as well as a small priming tank (see photographs in Appendix C). Sampling revealed that soils immediately around the UST had gasoline range TPH and BTEX contamination above Method A CULs. The UST was pumped of its contents, inerted, and removed, and the priming tank was removed. These tanks were reportedly transported off-site for disposal. The resulting pit was over-excavated until the field screening with a Photo-Ionization Detector (PID) showed low readings from soils remaining. Confirmation soil samples, taken from the four sidewalls and the bottom of the excavation, yielded no concentrations above laboratory reporting limits of gasoline range TPH and BTEX. Lead in the samples was below Method A CULs (see Table 1). The bottom sample was, also, analyzed for n-hexane and naphthalenes. This sample revealed no concentrations of these analytes above laboratory reporting limits. The contaminated soil
was taken off-site for disposal. The excavation was backfilled.
Adapt’s UST removal report concludes as follows:
“The results of the soil sampling activities performed after completion of the UST removal
activities indicated no detectable concentrations of petroleum hydrocarbons and only relatively low
levels of lead (at concentrations below Ecology Method A soil cleanup levels) along the bottom
and sidewalls of the UST removal excavation. As such, it is Adapt’s professional opinion that no
further soil excavation is warranted at this time.” Adapt’s review of regulatory agency information revealed that State of Washington Department of Ecology issued a No Further Action determination on February 25, 2015 based on Adapt’s report.
2.0 EXCAVATION ACTIVITIES IN 2018
2.1 Fire Hydrant Connection Trench
Temporary Soil Stockpile Sampling
Adapt was notified by Cary Fisher with Western International that soil exhibiting petroleum odors
was encountered during excavation work completed on August 20, 2018 associated with a fire
hydrant connection to a water main located beneath Lake Washington Boulevard North in the City
of Renton right-of-way (ROW). The impacted soil from this trench was temporarily stockpiled directly east of the trench location (see Figure 4). Personnel from Earth Solutions NW reportedly collected two (2) soil samples from this stockpile on August 20, 2018 and submitted these samples to OnSite Environmental Inc. for analytical testing. Laboratory testing of two soil samples collected from this area (identified as samples “1” and “2” indicated that gasoline range TPH had been detected at concentrations above the Method A Soil CUL for Unrestricted Land Uses (CUL) of 100 parts-per-million (ppm) (see Table 2). Motor oil range TPH and ethylbenzene were also detected in these two soil samples, but the detected concentrations were below their respective Method A Soil CULs.

Excavation Sidewall and Bottom Sampling
On September 12, 2018, Adapt personnel collected soil samples from the sidewalls and bottom of the trench excavation completed for the fire hydrant connection in the City of Renton ROW (see Figure 4). A shovel was used to expose new sidewall soils just prior to sampling and the bucket of an excavator was used to expose new bottom soils just prior to sampling to ensure that “fresh” samples were obtained for analytical testing (in accordance with Section 6.8.3 Soil Characterization – Sampling Excavation Margins of State of Washington Department of Ecology’s Guidance for Remediation of Petroleum Contaminated Sites, Publication No. 10-09-057, dated June 2016). Discrete soil samples for volatile compounds were collected in compliance with EPA Method 5035A. Samples were collected using a Power Stop Handle and Easy Draw Syringe. The syringe was pushed into the soil to obtain an approximately 5-gram soil sample. The soil sample was then placed in an empty 40 ml glass vial with a Teflon® lined lid with septum. Discrete soil samples from non-volatile compounds were collected using a gloved hand and transferred to a clean 4-ounce glass jar with a Teflon® lined lid. The jars were filled minimizing
headspace. All collected samples were immediately stored at 4 degrees C and transported to
Friedman & Bruya’s laboratory in Seattle, Washington for the following analyses under Adapt’s
chain-of-custody procedures:
• Gasoline range TPH by State of Washington Department of Ecology Method NWTPH-
Gx with BTEX by EPA Method 8021B.
• Lead by EPA Method 200.8.
Gasoline range TPH was detected at a concentration above the Method A Soil CUL along the
northern side of the fire hydrant connection excavation (sample ROW-6). The analytical testing
results also indicated gasoline range TPH were detected in samples ROW-5:4’ but the detected
concentration was below the Method A Soil CUL of 100 ppm. Ethylbenzene was detected in samples ROW-5:4' and ROW-6:4’; xylenes were detected in samples ROW-5:4' and ROW-6:4’; and toluene was detected in samples ROW-6:4’; but all of these detected concentrations were below their respective Method A Soil CULs. Gasoline range TPH and BTEX were not detected in any of the other soil samples collected from the fire hydrant connection trench excavation. Lead was detected at concentrations varying from 2.44 to 4.03 ppm in the collected samples, but these detected concentrations were below the Method A Soil CUL of 250 ppm. A summary of the soil analytical testing results is presented in Table 2 and a copy of the analytical laboratory report is presented in Appendix C.

2.2 Storm Sewer Trench
Excavation Sidewall and Bottom Sampling On August 28-29, 2018 and September 12, 2018, Adapt personnel collected soil samples from the sidewalls and bottom of the trench excavation completed for a new storm sewer line located in the City of Renton ROW (see Figure 4). The soil samples from the storm sewer trench were collected with the bucket of an excavator, with the actual discrete samples collected from soils that had not contacted the sides of the bucket (in accordance with Section 6.8.3 Soil Characterization – Sampling Excavation Margins of State of Washington Department of Ecology’s Guidance for Remediation of Petroleum Contaminated Sites, Publication No. 10-09-057, dated June 2016). Discrete soil samples for volatile compounds were collected in compliance with EPA Method 5035A. Samples were collected using a Power Stop Handle and Easy Draw Syringe. The syringe was pushed into the soil to obtain an approximately 5-gram soil sample. The soil sample was then placed in an empty 40 ml glass vial with a Teflon® lined lid with septum. Discrete soil samples from non-volatile compounds were collected using a gloved hand and
transferred to a clean 4-ounce glass jar with a Teflon® lined lid. The jars were filled minimizing
headspace. All collected samples were immediately stored at 4 degrees C and transported to
Friedman & Bruya’s laboratory in Seattle, Washington for the following analyses under Adapt’s
chain-of-custody procedures:
• Gasoline range TPH by State of Washington Department of Ecology Method NWTPH-
Gx with BTEX by EPA Method 8021B.
• Lead by EPA Method 200.8.
The analytical testing results for these samples indicated gasoline range TPH were detected in
samples ROW-1:5’, ROW-2:5’, ROW-3:5’, ROW-8:5’, and ROW-8:6’, but all of the detected
concentrations were below the Method A Soil CUL of 100 ppm. Ethylbenzene was detected in samples SS-3:5’, ROW-1:5’, ROW-2:5’, ROW-3:5”, ROW-8:5’, and ROW-8:6’; xylenes were detected in samples SS-3:5’, ROW-1:5’, ROW-2:5’, and ROW-8:6’; and toluene was detected in samples ROW-1:5” and ROW-8:6’; but of these detected concentrations were below their respective Method A Soil CULs. Gasoline range TPH and BTEX were not detected in any of the other soil samples collected from the storm sewer trench excavation. Lead was detected at concentrations varying from 2.96 to 4.83 ppm in the collected samples, but these detected concentrations were below the Method A Soil CUL of 250 ppm. A summary of the soil analytical testing results is presented in Table 3 and a copy of the analytical laboratory report is presented in Appendix C. 2.3 Combined Soil Stockpile
Soil excavated from the fire hydrant connection trench was initially stockpiled directly east of this
trench location. However, due to access issues associated with excavation of the storm sewer
trench, this stockpile was moved further to the east and placed on a plastic liner (see Figure 4 for
location). Soils with possible petroleum odors excavated from the storm sewer trench were added
to this stockpile. On August 29, 2018, Adapt personnel collected two soil samples (Stockpile-01
and Stockpile-02) from the combined soil stockpile that consisted of soil removed from the fire
hydrant and storm sewer trench excavations. The stockpile soil samples were collected through
the use of a gloved hand and were collected at a depth of approximately 6 to 12 inches into the
stockpile to obtain “fresh” samples for analytical testing. After completion of the soil sampling

work, this stockpile was covered with a plastic liner and a wood berm was constructed around the
perimeter of the stockpile.
Discrete soil samples for volatile compounds were collected in compliance with EPA Method 5035A. Samples were collected using a Power Stop Handle and Easy Draw Syringe. The syringe was pushed into the soil to obtain an approximately 5-gram soil sample. The soil sample was then placed in an empty 40 ml glass vial with a Teflon® lined lid with septum. Discrete soil samples from non-volatile compounds were collected using a gloved hand and transferred to a clean 4-ounce glass jar with a Teflon® lined lid. The jars were filled minimizing headspace. All collected samples were immediately stored at 4 degrees C and transported to Friedman & Bruya’s laboratory in Seattle, Washington for the following analyses under Adapt’s chain-of-custody procedures: • Gasoline range TPH by State of Washington Department of Ecology Method NWTPH-Gx.
• Diesel and motor oil range TPH by State of Washington Department of Ecology Method
NWTPH-Dx.
• Volatile organic compounds (VOCs) by EPA Method 8260.
• Lead by EPA Method 200.8.
Gasoline range TPH was detected in samples Stockpile-01 (120 ppm) and Stockpile-02 (420
ppm), which are both above the Method A Soil CUL of 100 ppm. Diesel range TPH was detected
in sample Stockpile-02 (170 ppm), but this detected concentration is below the Method A Soil CUL
of 2,000 ppm. Multiple gasoline associated VOC analytes and lead were detected in samples
Stockpile-01 and Stockpile-02, but the detected concentrations were below their respective
Method A and Method B Soil CULs (see Table 4).
The stockpiled soil was loaded into dump trucks and transported to Cadman’s facility in Everett, Washington for thermal treatment on September 7, 2018. 3.0 CONCLUSIONS AND RECOMMENDATIONS Review of historical documents indicates that a gasoline station was located near the western portion of the subject property from approximately 1920 through the 1950s/1960s. This former gasoline station reportedly utilized one pump island with two dispensers that appeared to be located near the west end of the location of the relic 450 gallon UST and small primer tank (less than 5 gallons in size) that were removed in 2014. No remnants of the pump island, dispensers, or relic fuel lines were observed during the UST removal activities completed in 2014 or during the trench excavation work completed in 2018. The soil sampling completed during removal of the relic gasoline UST on the subject property in 2014 did not indicate any detectable concentrations of either gasoline range TPH or BTEX and State of Washington Department of Ecology issued a No Further Action determination for the subject property on
February 25, 2015 based on the findings of the UST removal and assessment work.
Review of the soil sampling completed along the sidewalls and bottom of the sanitary sewer
trench and fire hydrant connection trench excavations, located within the City of Renton ROW,
indicates the following: no detectable concentrations of gasoline range TPH were detected in
the soil samples collected from the east side of the storm sewer trench (subject property side of
the ROW); soil samples collected from the western side of the storm sewer trench exhibited

gasoline range TPH concentrations varying from 10 to 81 ppm; and gasoline range TPH was
detected in soil from the fire hydrant connection excavation at concentrations varying from 940
to 1,000 ppm. These sampling results suggest the petroleum impacted soils in this area is likely associated with an off-site release or impacted relic fill materials located within the City of Renton ROW as the observed gasoline range TPH concentrations increase moving away from the location of the historical on-site gasoline station to the west and southwest. Typically, contaminant concentrations decrease with an increase in the distance from the source area due to natural degradation, dilution, and dispersion processes. If the contamination in the City of Renton ROW had originated from the subject property, we expect to see higher contaminant concentrations along the eastern storm sewer trench sidewall (subject property side of the ROW) and lower contaminant concentrations along the western storm sewer trench sidewall and fire hydrant connection excavation sidewalls. Based on the depth and number of underground utilities located within the City of Renton ROW, it is likely that an undocumented contaminant release from an off-site historic contaminant source or historic placement of contaminated fill is
responsible for the contamination recently documented in the City of Renton ROW located west
of the subject property.
4.0 LIMITATIONS
Information contained in this report is based upon site characterization, field observations, and
the laboratory analyses completed for this study. Conclusions presented are professional
opinions based upon our interpretation of the analytical laboratory test results, as well as our
experience and observations during the field activities. The field oversight and sampling, as
well as the analytical scope were completed within the subject property and proposal
constraints. Adapt’s observations and the analytical data are limited to the vicinity of each
sampling location and do not necessarily reflect conditions across the subject property. No other warranty, express or implied is made. In the event that additional information regarding either the subject property or surrounding properties becomes known, or changes to existing conditions occurs, the conclusions in this report should be reviewed, and if necessary, revised to reflect the updated information. Project specific limitations are presented in the appropriate sections of this report. Given that our assessment was limited and peripheral to the potential source areas, it is possible that a release(s) may have occurred that was (were) not observed during our assessment. If future subsurface work encounters stained, odorous, or otherwise contaminated soils, it would be prudent to manage such soils as contaminated soils, which may include additional analytical testing and off-site treatment or disposal. If future subsurface work encounters subsurface features of potential environmental impact, it would be prudent to assess and treat such subsurface features according to applicable regulations.
This report has been prepared for the exclusive use of Western International and their agents
for specific application to the subject property. Use or reliance upon this report by a third is at
their own risk. Adapt does not make any representation or warranty, express or implied, to

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 compound 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. Compounds in the sample matrix interfered with the quantitation of the analyte.
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 compound 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. Compounds in the sample matrix interfered with the quantitation of the analyte.
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.

CASE NARRATIVE
This case narrative encompasses samples received on August 29, 2018 by Friedman &
Bruya, Inc. from the Adapt Engineering Residence Inn Property WA18-19710-ENV
project. Samples were logged in under the laboratory ID’s listed below.
Laboratory ID Adapt Engineering
808648 -01 Stockpile-01
808648 -02 Stockpile-02
Methylene chloride was detected in the 8260C analysis of samples Stockpile-01 and
Stockpile-02. The data were flagged as due to laboratory contamination.
Several compounds in the 8260C laboratory control sample exceeded the acceptance
criteria. The analytes were not detected in the samples, therefore the data were
acceptable.
All other quality control requirements were acceptable.

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 compound 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. Compounds in the sample matrix interfered with the quantitation of the analyte.
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.
