The activities described in this report were conducted in July 2006. The Washington State Department of Ecology (Ecology) UST site number is. 4488. The site is shown relative to surrounding features in the Vicinity Map, Figure 1. The excavation sample locations are shown in Figure 2. SITE CONDITIONS The surface of the site is relatively level and has an approximate elevation of 130 feet above mean sea level. The site is located on the southeast corner of Tukwila Parkway and Andover Park E. Christensen Road borders the property to the east and a business park borders the property to the south. The site consists of a lot formerly occupied by a convenience store and a gasoline service station. The site is currently owned by Shell Oil Product US. SITE GEOLOGY AND HYDROLOGY Soil conditions observed in the excavation generally consisted of brown and gray fine sand with silt and occasional gravel. Pea -gravel backfill was observed surrounding the USTs. Groundwater was not encountered during excavation activities to a depth of fourteen feet below ground surface (bgs). PURPOSE AND SCOPE Our scope of services for the UST removal and closure is presented below. The purpose of our study was to close the tank in accordance with Ecology's "Guidance for Site Checks and Site Assessments for Underground Storage Tanks." GeoEngineers' specific scope of services completed for each task follows. UST AND HYDRAULIC HOIST SYSTEM REMOVAL AND CLOSURE 1. Observed and documented the removal of six USTs, associated product piping and dispensers and two hoists. 2. Obtained soil samples in general accordance with Washington Administrative Code (WAC) 173-340 from the UST excavations. 3. Field screened soil encountered during excavation activities using visual, sheen and headspace vapor methods (using a photoionization detector [PID]) for the presence of petroleum hydrocarbons and volatile organic compounds. 4. Submitted selected soil samples from the UST excavation for analyses of compounds listed in Tables 1, 2 and 3. 5. Submitted a Site Check/Site Assessment Checklist for USTs to Ecology (attached). File No. 9876-098-02 August 2, 2006 Page 1 GEOENGINEERS� UST AND HYDRAULIC REMOVAL AND CLOSURE GENERAL Cowlitz Clean Sweep, Inc. (CCS) inerted the tanks on the morning of July 5, 2006 in preparation for removal. CCS excavated and removed the USTs on July 5, 6 and 10, 2006. A representative of GeoEngineers, who is registered with Ecology to perform UST site checks and site assessments, was present to observe UST removal operations and document the conditions of the tanks. A GeoEngineers' representative was also on site during UST removal to visually observe the soils encountered and field screen soil samples obtained from the limits of the excavation and soil stockpile. Selected samples from the excavation were submitted for chemical analytical testing. Soil Sampling activities were conducted in general accordance with Ecology's "Guidance for Remediation of Petroleum Contaminated Soils." UST REMOVAL The three double walled fiberglass 10,000 -gallon gasoline USTs and one diesel UST were removed. The tops of the USTs were buried approximately 4 feet below ground surface (bgs). The diameter of the USTs was approximately 8 feet. The heating oil UST was a double walled fiberglass, 1,000 -gallon tank. The top of the heating oil UST was buried approximately 2 feet bgs. The diameter of the UST was approximately 5 feet. The waste oil UST was a double walled fiberglass, 500 -gallon tank. The top of the waste oil UST was buried approximately 2 feet bgs. The diameter of the UST was approximately 4 feet. The USTs were observed to be in good condition, with no cracks or leaking observed. The fiberglass product lines from the gasoline and diesel fuel tanks to the east wall of the associated UST excavation generally appeared to be in good condition. The Underground Storage Tank Site Check/Site Assessment Checklist is provided in Appendix A. The excavation to remove the gasoline and diesel fuel USTs was completed at a depth of approximately 14 feet bgs. The excavation to remove the heating oil UST was completed to a depth of approximately 9 feet bgs, and the excavation to remove the waste oil UST was completed to a depth of approximately 8 feet bgs. Native soil observed in the walls of the excavations generally consisted of brown fine sand with silt and occasional gravel. Groundwater was not observed during UST excavation activities. UST EXCAVATION SOIL SAMPLING Twenty-six discrete soil samples were obtained from the limits of the UST and dispenser excavations on July 5, 6 and 10, 2006. Field screening results did not indicate the likely presence of hydrocarbons in any samples from the UST excavations. Contaminants of concern either were not detected or were detected at concentrations less than the MTCA Method A cleanup levels in the soil samples with three exceptions. Concentrations of benzene in samples EX -3-14.0 (obtained from the base of the north gasoline UST), EX -8-12.0 (obtained from the NW sidewall of the gasoline and diesel UST excavation) and EX -14-3.0 (obtained from the base of the NE dispenser) exceed the MTCA Method A Cleanup level of 0.03 milligrams per kilogram (mg/kg). Field screening methods are described in Attachment B. Chemical analytical results are summarized in Table 1 through 3. Laboratory reports and our review of the laboratory quality control data are presented in Appendix C. File No. 9876-098-02 August 2, 2006 Page 2 GEOENGINEERS HYDRAULIC HOIST EXCAVATION The excavations to remove two hydraulic hoists were completed to a depth of approximately 10 feet bgs. Native soil observed in the walls of the excavations generally consisted of brown and gray fine sand with silt. One sample (EX -15-10.0) was obtained from the base of the north hoist excavation and one sample (EX -16-10.0) was obtained from the base of the south hoist excavation. Contaminants of concern were either not detected or were detected at a concentration less than the associated MTCA cleanup levels in each of the samples. UST AND HYDRAULIC HOIST EXCAVATION BACKFILLING The excavation was backfilled by CCS. Pea gravel that had been excavated from the UST excavations and stockpiled on-site and imported pit run were used as backfill in the excavations. GeoEngineers did not observe the backfilling activities. SUMMARY Six USTs and two hydraulic hoists were excavated and removed from the site in July 2006. Contaminants of concern either were not detected or were detected at concentrations less than the MTCA Method A cleanup levels in soil samples obtained from the limits of the excavations with three exceptions. Concentrations of benzene exceed MTCA Method A Cleanup levels in soil remaining beneath the location of the former northeast fuel dispenser, the northwest sidewall of the UST excavation and beneath the former location of the northernmost gasoline UST. LIMITATIONS We have prepared this report for use by Shell Oil Products US and its authorized agents. The information contained herein is not applicable to other sites. Our interpretations of subsurface conditions are based on GeoEngineers' field observations and chemical analytical data for soil samples from relatively widely - spread sampling locations at the site. It is possible that petroleum hydrocarbons exist beneath portions of the site that were not explored, sampled or analyzed.

GEOENGINEERS APPENDIX B FIELD METHODS APPENDIX B FIELD METHODS SAMPLE COLLECTION AND HANDLING Soil excavation was performed at the former Shell service station by Saybr Contractors, Inc. of Tacoma, Washington, on June 2006. A trackhoe was used to excavate soil. Soil samples obtained from the excavation were obtained by two different methods. The first method used a disposable plastic syringe to collect approximately 13 grams of soil from the excavation side walls or trackhoe bucket. This soil was then placed in a 40 ml vial which contained a methanol preservative provided by the analytical laboratory. The second method used a stainless steel trowel to collect soil and placed it in a 4 -oz laboratory prepared jar, filled to minimize headspace. The samples were placed in an iced cooler pending transport to the analytical laboratory. Each sample that was submitted for analysis was identified by a unique sample designation that corresponded to its mapped sample location and depth. Chain -of -custody procedures were followed in transporting the samples to the laboratory. Equipment used to obtain soil samples was decontaminated (trowel) prior to each use using a Liqui-Nox® solution and a distilled water rinse. FIELD SCREENING OF Sott SAMPLES A representative from our staff field screened soil samples obtained from the remedial excavation. Field screening results are used as a general guideline to delineate areas with possible petroleum hydrocarbon concentrations. In addition, screening results are used to aid in the selection of soil samples for chemical analysis. The screening methods used include (1) visual screening, (2) water sheen screening and (3) headspace vapor screening. Visual screening consists of inspecting the soil for stains indicative of petroleum hydrocarbons. Visual screening is generally more effective when hydrocarbons are heavier, such as motor oil, or when hydrocarbon concentrations are high. Water sheen screening and headspace vapor screening are more sensitive methods that have been effective in detecting contamination at concentrations less than regulatory cleanup levels. However, field screening results are site-specific. The effectiveness of field screening varies with temperature, moisture content, organic content, soil type and age of contaminant. The presence or absence of a sheen or headspace vapors does not necessarily indicate the presence or absence of petroleum hydrocarbons. Water sheen screening involves placing soil in water and observing the water surface for signs of sheen. Sheen screening may detect both volatile and nonvolatile petroleum hydrocarbons. Sheen classifications are as follows: No Sheen (NS) Slight Sheen (SS) Moderate Sheen (MS) Heavy Sheen (HS) No visible sheen on water surface. Light, colorless, dull sheen; spread is irregular, not rapid; sheen dissipates rapidly. Natural organic matter in the soil may produce a slight sheen. Light to heavy sheen; may have some color/iridescence; spread is irregular to flowing, may be rapid; few remaining areas of no sheen on water surface. Heavy sheen with color/iridescence; spread is rapid; entire water surface may be covered with sheen. File No. 9876-098-02 August 2, 2006 Page B-1 GEOENGINEERLO Headspace vapor screening may identify volatile petroleum hydrocarbon compounds and involves placing a soil sample in a plastic sample bag. Air is captured in the bag and the bag is shaken to expose the soil to the air trapped in the bag. The probe of a MicroTIP® photoionization detector is inserted in the bag, the MicroTIP® then measures the concentration of volatile organic vapors present within the sample bag headspace. The MicroTIP® measures photoionizable vapor concentrations in parts per million (ppm) and is calibrated to isobutylene. The MicroTIP® is designed to quantify concentrations up to 3,000 ppm. A lower threshold of significance of 0 ppm was used in this application. File No. 9876-098-02 August 2, 2006 Page B-2 GEOENGINEERLO GEOENGINEERS APPENDIX C CHEMICAL ANALYTICAL PROGRAM APPENDIX C CHEMICAL ANALYTICAL PROGRAM ANALYTICAL METHODS Chain -of -custody procedures were followed during the transport of the field samples to the analytical laboratory. The samples were held in cold storage pending extraction and/or analysis. The analytical results, analytical methods reference and laboratory quality control records are included in this appendix. The analytical results are also summarized in the text and tables of this report. ANALYTICAL DATA REVIEW The laboratory maintains an intemal quality assurance program as documented in its laboratory quality assurance manual. The laboratory uses a combination of blanks, surrogate recoveries, duplicates, matrix spike recoveries, matrix spike duplicate recoveries, blank spike recoveries and blank spike duplicate recoveries to evaluate the validity of the analytical results. The laboratory also uses data quality goals for individual chemicals or groups of chemicals based on the long-term performance of the test methods. The data quality goals were included in the laboratory reports. The laboratory compared each group of samples with the existing data quality goals and noted any exceptions in the laboratory report. The laboratory quality control and data quality exceptions documented by the laboratory were reviewed by GeoEngineers using the applicable data validation guidelines from the following documents: "Laboratory Data Validation Functional Guidelines for Evaluating Inorganic Analyses" dated July 1988 (EPA document number EPA540/R94/083) and "USEPA Contract Laboratory Program National Functional Guidelines for Organic Data Review" dated February 1994 (EPA document number EPA540/R94/012). ANALYTICAL DATA REVIEW SUMMARY Based on our data quality review, it is our opinion that the analytical data are of acceptable quality for their intended use.

Please refer to the sample chromatogram. J - Estimated value. P-03 - Greater than 40% difference between two dissimilar columns. After evaluation, the lower result has been reported. Q-02 - The spike recovery for this QC sample is outside of NCA established control limits due to sample matrix interference. Q-07 - The RPD value for this QC sample is above the established control limit. Review of associated QC indicates the high RPD does not represent an out -of -control condition for the batch. Q -4I - This analyte had a high bias in the associated calibration verification standard. RP -4 Due to the low levels of analyte in the sample, the duplicate RPD calculation does not provide useful information. Laboratory Reporting Conventions: DET Analyte DETECTED at or above the Reporting Limit. Qualitative Analyses only. ND Analyte NOT DETECTED at or above the reporting limit (MDL or MRL, as appropriate). NR/NA Not Reported / Not Available dry Sample results reported on a Dry Weight Basis. Results and Reporting Limits have been corrected for Percent Dry Weight. Sample results and reporting limits reported on a Wet Weight Basis (as received). Results with neither 'wet' nor 'dry' are reported on a Wet Weight Basis. RPD RELATIVE PERCENT DIFFERENCE (RPDs calculated using Results, not Percent Recoveries). MRL - METHOD REPORTING LIMIT. Reporting Level at, or above, the lowest level standard of the Calibration Table. MDL* METHOD DETECTION LIMIT. Reporting Level at, or above, the statistically derived limit based on 40CFR, Part 136, Appendix B. *MDLs are listed on the report only if the data has been evaluated below the MRL. Results between the MDL and MRL are reported as Estimated Results. Dil Dilutions are calculated based on deviations from the standard dilution performed for an analysis, and may not represent the dilution found on the analytical raw data. Reporting limits (MDLs and MRL5) are adjusted based on variations in sample preparation amounts, analytical dilutions and percent solids, where applicable. wet Reporting Limits Electronic - Electronic Signature added in accordance with TestAmerica's Electronic Reporting and Electronic Signatures Policy.

ENVIRONMENTAL SERVICES ARE PERFORMED FOR SPECIFIC PURPOSES, PERSONS AND PROJECTS This report has been prepared for the exclusive use of Shell Oil Products US, their authorized agents and regulatory agencies. This report is not intended for use by others, and the information contained herein is not applicable to other sites. GeoEngineers structures our services to meet the specific needs of our clients. For example, an environmental site assessment study conducted for a property owner may not fulfill the needs of a prospective purchaser of the same property. Because each environmental study is unique, each environmental report is unique, prepared solely for the specific client and project site. No one except Shell should rely on this environmental report without first conferring with GeoEngineers. This report should not be applied for any purpose or project except the one originally contemplated. THIS ENVIRONMENTAL REPORT IS BASED ON A UNIQUE SET OF PROJECT -SPECIFIC FACTORS This report has been prepared for UST removal and excavation activities at the former Shell Service Station site. GeoEngineers considered a number of unique, project -specific factors when establishing the scope of services for this project and report. Unless GeoEngineers 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 project changes were made. If important changes are made after the date of this report, GeoEngineers should be given the opportunity to review our interpretations and recommendations and provide written modifications or confirmation, as appropriate. RELIANCE CONDITIONS FOR THIRD PARTIES Our report was prepared for the exclusive use of our Client. 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 the Client and generally accepted environmental practices in this area at the time this report was prepared. ENVIRONMENTAL REGULATIONS ARE ALWAYS EVOLVING Some substances may be present in the site vicinity in quantities or under conditions that may have led, or may lead, to contamination of the subject site, but are not included in current local, state or federal Developed based on material provided by ASFE, Professional Firms Practicing in the Geosciences; www.asfe.org. File No. 9876-098-01 August 2. 2006 Page D-1 GEOENGINEERS� regulatory definitions of hazardous substances or do not otherwise present current potential liability. GeoEngineers cannot be responsible if the standards for appropriate inquiry, or regulatory definitions of hazardous substance, change or if more stringent environmental standards are developed in the future. UNCERTAINTY MAY REMAIN AFTER COMPLETION OF REMEDIAL ACTIVITIES Remediation activity completed in a portion of a site cannot wholly eliminate uncertainty regarding the potential for contamination in connection with a property. Our interpretation of subsurface conditions in this study is based on field observations and chemical analytical data from widely -spaced sampling locations. It is always possible that contamination exists in areas that were not explored, sampled or analyzed. 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 GeoEngineers before applying this report to determine if it is still applicable. SOIL AND GROUNDWATER END USE The cleanup levels referenced in this report are site- and situation -specific. 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. GeoEngineers should be contacted prior to the export of soil or groundwater from the subject site or reuse of the affected media on site to evaluate the potential for associated environmental liabilities. 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 site in instances that we were not aware of or could not control. MOST ENVIRONMENTAL FINDINGS ARE PROFESSIONAL OPINIONS Our interpretations of subsurface conditions are based on field observations and chemical analytical data from widely spaced sampling locations at the site. Site exploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken. GeoEngineers 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. READ THESE PROVISIONS CLOSELY 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. GeoEngineers includes these explanatory "limitations" provisions in our reports to help reduce such risks. Please confer with GeoEngineers if you are unclear how these "Report Limitations and Guidelines for Use" apply to your project or site. File No. 9876-098-02 August 2. 2006 Page D-2 GEOENGINEERS_..0. GEOTECHNICAL, GEOLOGIC AND GEOENVIRONMENTAL REPORTS SHOULD NOT BE INTERCHANGED The equipment, techniques and personnel used to perform an environmental study differ significantly from those used to perform a geotechnical or geologic study and vice versa. For that reason, a geotechnical engineering or geologic report does not usually relate any environmental findings, conclusions or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Similarly, environmental reports are not used to address geotechnical or geologic concerns regarding a specific project. BIOLOGICAL POLLUTANTS GeoEngineers' Scope of Work specifically excludes the investigation, detection, prevention or assessment of the presence of Biological Pollutants. Accordingly, this report does not include any interpretations, recommendations, findings, or conclusions regarding the detecting, assessing, preventing or abating of Biological Pollutants and no conclusions or inferences should be drawn regarding Biological Pollutants, as they may relate to this project. The term "Biological Pollutants" includes, but is not limited to, molds, fungi, spores, bacteria, and viruses, and/or any of their byproducts. If Shell desires these specialized services, they should be obtained from a consultant who offers services in this specialized field.
