This report summarizes the tank removal and assessment conducted on November 5 and 6, 2008. Site Description The subject property, which is also addressed as 4208 South 116th Street, is located at the northeast corner of the intersection of 42nd Avenue South and South 116th Street in a mixed commercial and residential neighborhood in Tukwila, Washington. The site is zoned commercial and consists of an irregular-shaped parcel approximately 0.3 acres in size which is situated approximately 80 feet east-northeast of a 90 -degree elbow of the Duwamish River. The site surface is nearly horizontal, and is occupied by a 1930 - vintage, 2,400 square foot single -story wood -frame structure. The structure houses Riverside Interiors showroom and offices (a flooring and carpet sales and installation business). Two small wood -frame structures used as storage space and a residence are situated just to the east of the Riverside Interiors building. The remainder of the property is used for driveway and parking areas. The area west of the site structure consists of a concrete -paved parking lot, and northern portions of the site consist of unpaved driveway and parking areas. The location of the site is indicated on the Vicinity Map, Figure 1, and the Site Plan, Figure 2 attached to this report. The layout of the underground storage tanks (USTs) in relationship to the Riverside Interiors building, as well as soil sampling locations, are depicted on the Exploration Map, Figure 3. The subject site had two (2) unregistered out -of -use underground storage tanks (USTs) including 576 -gallon capacity (Tank T1) and 288 -gallon capacity (Tank T2) steel - constructed, single-wall tanks, both of which were reportedly installed in 1930. The tanks were used to store leaded gasoline for Standard Oil Products brand gasoline sales for the store which formerly occupied the site. Assessor records on file with the Washington State Archives (see Appendix B, King County Assessor Records) indicate that the Riverside Interiors portion of the site was originally occupied by Bill Goldsmith's PSQ Store and gas station which was constructed in 1930. The exact length of time that the tank systems were in use is not known, however the gasoline sales and store had ceased operations by 1957, giving way to a cabinet shop and paint store. Riverside Interiors December 16, 2008 JN 08-01 Other portions of the site were occupied by two single-family residences constructed in 1908 and 1920 (on Lots 1 and 5 respectively) which were torn down by 1968. A small 1908 -vintage single -story structure which is still currently present east of the Riverside Interiors building served as a snack bar and barber shop in the past, and more recently as an apartment unit. Referring to Figure 2, Site Plan, the underground storage tanks for the store were located below the current concrete -surfaced parking lot several feet west of the Riverside Interiors building. Referring to historical assessor information in Appendix B, the fuel dispensers were located in a concrete single -island configuration that had dimensions of 2 feet in width and 12 feet in length. According to Mr. Decker (property owner), the dispensers and island had been removed at an unknown date prior to his purchase of the site. Surrounding properties consists of: North: City of Tukwila "Sweeney" fire station East: Several single family residences, with a Burlington Northern Railroad Corridor and Interstate 5 further to the east South: South 116`s Street, with a residential 4-plex further to the south West: 42nd Avenue South, with a steep embankment, vacant residential -zoned parcels owned by the City of Tukwila, and the Duwamish River further to the west. Topographically, the site is situated approximately 20 feet above sea level. Based upon topography and local drainage patterns, shallow groundwater is inferred to flow from the east toward the west (i.e. toward the Duwamish River) at a depth of approximately 20 feet below the ground surface. No groundwater was encountered during tank removal activities to the maximum explored depth of approximately 10 feet below the ground surface. Tank Removal Global Diving and Salvage (Global) was retained by the site owner, Mr. Dean Decker, to conduct the removal of two (2) USTs at the site. Global obtained a tank -removal permit from the City of Tukwila Fire Department, and scheduled a fire inspector to inspect the site and tanks prior to tank removal. On November 5, 2008, the concrete pad overlying the tanks was cut, broken, and removed. The concrete was transported via truck to LaFarge's West Marginal Way site for recycling. A backhoe was used to excavate soils down to the tops of the tanks to expose the tanks for inspection and access to investigate for the presence of fluids (if any) within the tanks. The tanks were sounded with a dip stick and found to be dry and empty.

Results of laboratory testing of the soil samples indicate that gasoline -range TPH, BTEX VOCs, total lead, and diesel -range TPH and heavy -oil range TPH were either not detected at the method reporting limits shown or were detected at trace concentrations only (i.e., at concentrations far less than the WDOE Method A cleanup levels). Based upon the results of field observations and screening as confirmed by laboratory testing, it would appear that successful closure by removal of the two (2) USTs was completed, that soils proximal to the tank systems are compatible with current WDOE method A cleanup levels, and that no further actions at the site with respect to the tank systems are warranted at this time. As previously discussed, WDOE tank closure assessment forms and documents are attached to this report as Appendix A, King County Assessor documents are attached as Appendix B, analytical laboratory testing reports are attached as Appendix C, and site photographs are attached as Appendix D. It has been my pleasure to assist you with this tank closure project. If I can be of further assistance, please don't hesitate to contact me. James R.

Soils were transferred directly into 4 -ounce sampling jars and 40 milliliter VOA vials, then immediately labeled and placed into zip -lock plastic bags and a cooler maintained at or below 4 degrees centigrade. Samples were maintained in this condition during transport to the project analytical laboratory. All soil samples were analyzed for gasoline -range total petroleum hydrocarbons (TPH) and the gasoline -associated volatile organic compounds (VOCs) benzene, toluene, ethylbenzene, and xylenes (BTEX) using gas chromatography by WDOE Method NWTPH-Gx and EPA Method 8021B. Four (4) selected samples were analyzed for diesel and heavy -oil range TPH by WDOE Method NWTPH-DX and three selected soil samples were analyzed for total lead by EPA Method 200.8. Laboratory Testing Results Friedman and Bruya, Inc., Seattle, Washington, a WDOE-accredited analytical laboratory, conducted soils testing by the methods discussed in the previous report section.

Riverside Interiors December 16, 2008 JN 08-01 On November 6, 2008, the tanks were conditioned to prevent explosion by a marine chemist from Sound Testing, Inc. The tanks were inerted by introducing carbon dioxide to displace oxygen until the tank atmospheres contained less than 6 percent oxygen (verified with an oxygen meter). The site and tanks were inspected by a City of Tukwila Fire Department inspector, and Global was authorized to proceed with removal of the tanks. The tanks were removed from their respective tank -hold excavations using a backhoe and chain, and were placed on the ground for inspection. Holes were cut in the tank tops to allow visual examination of the interior surfaces of the tanks. The tanks were then loaded onto a truck, secured, and transported to Seattle Iron and Metals Corporation for scrapping and recycling. Tank conditioning and recycling documents are included in Appendix A of this report. Both tanks T1 and T2 were of single-wall, steel construction and were cylindrical in shape. Tank Ti had dimensions of 42 inches in diameter and 8 feet in length, equating to approximately 576 gallons in capacity. Tank T2 had dimensions of 42 inches in diameter and 4 feet in length, with an approximate capacity of 288 gallons. As previously discussed, neither tank contained any liquids, although weak gasoline vapors were noted emanating from both tanks. The Tank Ti interior surfaces were moderately rusted, but Tank T2 interior surfaces were relatively unimpacted by rust or corrosion, and the factory stamp "USSP [US Steel Posco], San Francisco" was easily read. Exterior surfaces of the tanks exhibited visual evidence of a moderate degree of rust and/or corrosion, however no holes were found during close inspection of the tanks following removal. No evidence which might otherwise suggest release of gasoline or other petroleum substances was detected or noted during field screening of soils during or after tank removal using visual, olfactory, and photo -ionization detector (PID) vapor screening methodologies. Soils within the tank -hold excavation consisted of slightly moist, brown -to -gray colored fine -textured sand with occasional rounded gravel up to approximately one and one-half inch in diameter. No groundwater or groundwater seeps were present within the tank - hold excavations during or after removal of the tanks. Prior to tank removal, the concrete pad was cut and opened up to dimensions of approximately 20 feet square (see Figure 3). Prior to removal, the top of the tanks were approximately 32 inches below the concrete surface, and the tank inverts (bottoms) were approximately 74 inches (6 feet, 2 inches) below the concrete surface. The fuel -dispenser supply line ports were situated at the top of the west ends of the tanks. No tank fill or vent piping was present within the areas excavated and explored. Photographs of the site, excavation, tank removal, and backfilling activities are included with this report as Appendix D. Soil Sampling and Laboratory Testing Soils were sampled in accordance with WDOE sampling protocols for tank removal assessment where no evidence of a release is observed or detected during field screening efforts.

A1— More than one compound of similar molecule structure was identified with equal probablility. 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 this range fell outside of acceptance criteria. The value reported is an estimate. c - The presence of the analyte indicated may be due to carryover from previous sample injections. d - The sample was diluted. Detection limits may be raised due to dilution. ds - The sample was diluted. Detection limits are raised due to dilution and surrogate recoveries may not be meaningful. dv - Insufficient sample was available to achieve normal reporting limits and limits are raised accordingly. fb - The analyte indicated was found in the method blank. The result should be considered an estimate. 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. The variability is attributed to sample inhomogeneity. ht - The sample was extracted outside of holding time. Results should be considered estimates. ip - Recovery fell outside of normal control limits. Compounds in the sample matrix interfered with the quantitation of the analyte. j — The result is below normal reporting limits. 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 analyte result in the laboratory control sample is out of control limits. The reported concentration should be considered an estimate. jr - The rpd result in laboratory control sample associated with the analyte is 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 compound indicated 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 in a container not approved by the method. The value reported should be considered an estimate. pr — The sample was received with incorrect preservation. The value reported should be considered an estimate. ve - The value reported exceeded the calibration range established for the analyte. The reported concentration should be considered an estimate. vo - The value reported fell outside the control limits established for this analyte. x - The pattern of peaks present is not indicative of diesel. y - The pattern of peaks present is not indicative of motor oil. 9 Photo 15: Final compaction of fill.
