February 15, 2008 Mr. Max Boone ConocoPhillips Company 1230 W. Washington St., Suite 212 Tempe, Arizona 85281 RE: Due Diligence Site Assessment Report ConocoPhillips Site No. 2705492 21208 68th Avenue South

Kent, Washington ATC Project No. 34.75118.3328

Dear Mr. Boone:

ATC Associates Inc. (ATC) on behalf of ConocoPhillips Company (ConocoPhillips) presents the results of a Due Diligence Site Assessment conducted at the above-referenced site. The purpose of the investigation was to generate a baseline assessment of property conditions at the time of property transfer. The data reported herein was collected on behalf of ConocoPhillips, in general accordance with the Site-Specific Scope of Work (SOW) prepared by Shaw Environmental & Infrastructure, Inc. (Shaw) dated November 2, 2007 (Appendix A, attached). The data reported herein was not requested or required by a regulatory agency.

Activities included in the SOW performed are outlined below:

• Preparation of a site specific Health and Safety Plan (HASP); • Securing permits, if applicable, from the local permitting agency; • Collection of post-purge groundwater samples for laboratory analysis from

existing on-site monitor wells MW-1, MW-4, MW-5, MW-6, MW-7, TW-1 and TW-3 (a sample was not collected from monitor well TW-4 as it was unable to be opened);

• Waste profiling and disposal coordination (still underway); and • Preparation of a report summarizing due diligence assessment activities.

SITE DESCRIPTION

The site is an active service station located at 21208 68th Avenue South in Kent, Washington. The site’s current underground storage tank (UST) system configuration includes three fuel USTs and four dispenser islands. Limited background information is included in the SOW prepared by Shaw (Appendix A).

BASELINE SITE ASSESSMENT

Field Activities

On January 9, 2008, ATC personnel gauged and collected groundwater samples from existing on-site monitor wells MW-1, MW-4, MW-5, MW-6, MW-7, TW-1 and TW-3 shown on the attached Figure 1, Site Plan. Depth to groundwater in the wells ranged from 7.58 feet (MW-7) to 8.43 feet (MW-1 and MW-4) below the top of the well casing. One to three volumes of groundwater were purged from each monitoring well using a battery-operated pump during which time temperature, pH, and electrical conductivity were monitored to verify that groundwater conditions had stabilized prior to sample collection. Groundwater samples were then collected using disposable polyethylene bailers and transferred from the bailers into sample containers provided by the analytical laboratory. Groundwater sampling observations were recorded and are included as Appendix B, attached.

Laboratory Analytical Procedures

Groundwater samples collected during field activities were shipped under chain-of-custody (COC) protocol to Lancaster Laboratories, Inc. (Lancaster) in Lancaster, Pennsylvania. Lancaster is certified through the State of Washington Department of Ecology. Groundwater samples collected from monitor wells MW-1, MW-4, MW-5, MW-6, MW-7, TW-1 and TW-3 were analyzed for fuel oxygenates and halogenated volatile organic compounds (HVOC; including benzene, toluene, ethylbenzene and total xylenes [BTEX]) using Environmental Protection Agency (EPA) Method 8260B. Each sample selected was also analyzed for gasoline-, diesel- and heavy range organic-petroleum hydrocarbons using Northwest Total Petroleum Hydrocarbons (NWTPH) Modified method (NWTPH-Gx [C8 to C12], NWTPH-Dx DRO [C12 to C24] and NWTPH-Dx HRO [C>24 to C40], respectively). Additionally, the groundwater samples were analyzed for lead using EPA Method 6020. Laboratory analytical data for groundwater samples analyzed as part of this assessment are summarized in attached Table 1, Summary of Groundwater Analytical Data. The laboratory analytical report and COC document are provided as Appendix C, attached.

Waste Disposal

Investigation derived waste (IDW) generated during the field operations has been temporarily stored onsite pending characterization and disposal. A copy of the waste manifest(s) will be provided under separate cover once the IDW has been profiled and transported to an appropriate disposal facility.

FINDINGS

As shown in Table 1, laboratory analytical results for the groundwater samples selected for analysis indicate the following:

• Benzene was detected at a concentration of 150 micrograms per liter (μg/L) in the groundwater sample collected from monitor well TW-1.

ConocoPhillips Site No. 2705492 February 15, 2008 Page 3

2705492 Report

• Toluene was detected at a concentration of 17 μg/L in the groundwater sample collected from monitor well TW-1.

• Ethylbenzene was detected at a concentration of 87 μg/L in the groundwater sample collected from monitor well TW-1.

• Total xylenes were detected at a concentration of 195 μg/L in the groundwater sample collected from monitor well TW-1.

• Chlorobenzene was detected at a concentration of 1 J μg/L in the groundwater sample collected from monitor well TW-1.

• 1,2 – Dichlorobenzene was detected at a concentration of 2 J μg/L in the groundwater sample collected from monitor well TW-1.

• t-Butyl alcohol was detected at a concentration of 13 J μg/L in the groundwater sample collected from monitor well MW-4.

• NWTPH-Gx was detected at concentrations of 69 J μg/L, 88 J μg/L and 2,200 μg/L in the groundwater samples collected from monitor wells MW-1, MW-4 and TW-1, respectively.

• NWTPH-Dx DRO was detected at concentrations of 230 J μg/L and 370 J μg/L in the groundwater samples collected from monitor wells MW-4 and TW-1, respectively.

• Lead was detected at concentrations of 0.29 J μg/L, 1.5 μg/L and 1.7 μg/L in the groundwater samples collected from monitor wells MW-4, TW-1 and TW-3, respectively.

• No other analytes were detected in excess of their respective laboratory method detection limit (MDL) in any of the groundwater samples submitted for analysis.

It should be noted that the “J” notation after the analyte value indicates an estimated concentration between the laboratory MDL and the limit of quantitation.

Quality Control Summary

Client Name: ConocoPhillips Group Number: 1073037Reported: 01/23/08 at 08:49 AM

*- Outside of specification**-This limit was used in the evaluation of the final result for the blank(1) The result for one or both determinations was less than five times the LOQ.(2) The unspiked result was more than four times the spike added.

Matrix QC may not be reported if site-specific QC samples were notsubmitted. In these situations, to demonstrate precision and accuracy ata batch level, a LCS/LCSD was performed, unless otherwise specified in themethod.

Lancaster LaboratoriesExplanation of Symbols and Abbreviations

The following defines common symbols and abbreviations used in reporting technical data:

N.D. none detected BMQL Below Minimum Quantitation LevelTNTC Too Numerous To Count MPN Most Probable Number

IU International Units CP Units cobalt-chloroplatinate unitsumhos/cm micromhos/cm NTU nephelometric turbidity units

C degrees Celsius F degrees FahrenheitCal (diet) calories lb. pound(s)

meq milliequivalents kg kilogram(s)g gram(s) mg milligram(s)

ug microgram(s) l liter(s)ml milliliter(s) ul microliter(s)m3 cubic meter(s) fib >5 um/ml fibers greater than 5 microns in length per ml

< less than – The number following the sign is the limit of quantitation, the smallest amount of analyte which canbe reliably determined using this specific test.

> greater than

ppm parts per million – One ppm is equivalent to one milligram per kilogram (mg/kg), or one gram per million grams.For aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/l), because one liter ofwater has a weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter ofgas per liter of gas.

ppb parts per billion

Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weightbasis concentration to approximate the value present in a similar sample without moisture.
