SEGALE ASPHALT PLANT TUKWILA, WASHINGTON FOR M.A. SEGALE, INC. INTRODUCTION / 37a' S / This report summarizes the results of our observations during the removal of four USTs (underground storage tanks) at the site of the M. A. Segale Asphalt Plant in Tukwila, Washington. The site is located at 18501 Southcenter Parkway and is shown on the Vicinity Map, Figure 1. One 20,000 -gallon diesel storage tank, one 10,000 -gallon diesel storage tank, one 500 -gallon waste oil tank and one 500 -gallon heating oil tank were removed from the locations shown in Figure 2 between May 14 and May 20, 1991. The heating oil tank is not a regulated UST based on current Ecology (Washington State Department of Ecology) standards; however, the heating oil tank was removed as part of the waste oil tank excavation. No new tanks or facilities were installed. PURPOSE AND SCOPE The purpose of our geoenvironmental services was to observe and evaluate subsurface soil conditions in the UST excavations and to assist the contractor during removal of the USTs. Our scope of services completed includes the following. 1. Observe and document UST removal and soil cleanup activities, including the condition of the USTs (pitting, cracking, etc.) at the time of removal. 2. Field screen the soils to determine the location and relative severity of any soil contamination. 3. Advise the contractor regarding areas of soil contamination that require excavation and temporary stockpiling of contaminated soil. 4. Sample and test soils from the base and sides of the excavations completed for removal of the diesel tanks to_ evaluate the potential presence of hydrocarbon -contaminated soils. Geo Engineers 5. Sample and test soils from the base and sides of the excavation completed for removal of the waste oil tank excavation to evaluate the potential presence of hydrocarbon- and/or solvent-contaminated soils. 6. Provide technical liaison with the local fire department and/or Ecology. REMEDIAL ACTIVITIES GENERAL Segale (M.A. Segale, Inc.) excavated and removed the 20,000 -gallon steel diesel UST, the 10,000 -gallon steel diesel UST and the 350 -gallon steel waste oil UST at the site on May 14, 1991. The 500 -gallon steel heating oil UST was excavated and removed by Segale on May 20, 1991. A representative from our staff observed the tank removal operations on May 14 but was not present when the heating oil UST was removed on May 20. Mr. Kevin Hoskins, a licensed tank decommissioning supervisor employed by Joe Hall Construction Company, also observed the May 14 UST removal operations. A representative from our staff obtained soil samples from the limits of the UST excavations and the resulting soil stockpiles. A total of 43 soil samples were obtained from the excavations and soil stockpiles for chemical analysis. Two water samples were obtained from the 20,000 -gallon diesel tank excavation for chemical analysis. Field screening techniques and chemical analytical data were used to delineate the limits of the excavation. Field screening, ground water and soil sampling techniques are described in Appendix A. The former locations of the USTs, soil sampling locations and the approximated limits of the excavations are shown in Figure 2. A summary of field screening and soil chemical analytical results are presented in Tables 1 through 5. Laboratory reports are presented in Appendix B. SOIL AND GROUND WATER CLEANUP CRITERIA Ecology has adopted soil and ground water cleanup guidelines for petroleum contaminants at fuel storage sites under the MTCA (Model Toxics Control Act). MTCA Method A cleanup levels for ground water and soil are Geo, Engineers Compound TPH (gasoline) TPH (diesel) TPH (other) Benzene Ethylbenzene Toluene Total Xylenes Notes: "mg/kg" "pg/i" MTCA (4/28/91) Soil Ground water 100 mg/kg 1 mg/1 200 mg/kg 1 mg/1 200 mg/kg 1 mg/1 0.5 mg/kg 5 pg/1 20 mg/kg 30 pg/1 40 mg/kg 40 pg/1 20 mg/kg 20 pg/i signifies "milligrams per kilogram" signifies "micrograms per liter" DIESEL UST EXCAVATION NO. 1 Minor evidence of pitting and rusting was observed on the 20,000 -gallon diesel UST during tank removal operations. Petroleum staining was observed on soils exposed in the lower walls of the excavation and beneath the tank following removal. No holes were observed in the UST prior to removal. However, during excavation the tank was dented and ruptured. Product was not observed leaking from the ruptured tank during the removal operation. The UST excavation extended to a depth of approximately 11 to 12 feet. Ground water was encountered at a depth of approximately 10 feet below existing grade in the excavation. Backfill surrounding the tanks consisted of approximately 2 feet of gravel and sand overlying 8 feet of sand and silt. Native soil consisting of fine to medium sand with silt and occasional fine gravel was observed in the walls and base of the excavation. Eight soil samples (D-1 through D-5 and D-11 through D-13) were obtained from the initial limits of the excavation. The soil samples were analyzed for fuel hydrocarbons by modified EPA Method 8015. As mentioned in the discussion for DIESEL UST EXCAVATION NO. 2, observations and field screening indicated the potential presence of gasoline contaminated soils in that excavation. Soil sample D-11, located along the north wall of diesel UST excavation No. 1, was also analyzed for BETX (benzene, ethylbenz- ene, toluene and xylenes) by EPA Method 8020. A summary of the field screening and soil chemical analytical results is presented in Table 1. Fuel hydrocarbons and/or BETX were not detected in soil samples obtained from the east wall (D-1), west wall (D-2), south wall (D-3) and base (D-4 and D-5) of the excavation. Fuel hydrocarbons were detected at 3 Engineers concentrations greater than MTCA cleanup levels in soil samples obtained from the north wall (D-11), northwest base (D-12) and southwest base (D-13). Additional soil was removed from the north wall of the excavation and soil sample D-18 was obtained for chemical analysis of fuel hydrocarbons. Fuel hydrocarbons were detected at concentrations less than MTCA cleanup levels in soil sample D-18. Additional soil was removed from the northwest and southwest base of the excavation and soil samples D-16 and D-17 were obtained for chemical analyses of fuel hydrocarbons. Fuel hydrocarbons were detected at concentrations greater than MTCA cleanup levels in soil sample D-17 and less than MTCA cleanup levels in soil sample D-16. Additional soil was removed from the northwest corner of the excavation and soil sample D-20 was obtained. Fuel hydrocarbons were detected at concentrations less than MTCA cleanup levels in D-20. Soil removed from the excavation during UST removal operations was temporarily stockpiled on-site. Two water samples (D-15 and D-19) were obtained from the excavation for chemical analysis of fuel hydrocarbons. D-15 was also submitted for chemical analysis of BETX. Water sample D-15 was obtained on May 16, 1991. Fuel hydrocarbons, quantified as diesel, were detected at a concentration (5 mg/1) greater than MTCA cleanup levels in water sample D-15. BETX was detected at concentrations less than MTCA cleanup levels in water sample D-15. Northwest EnviroService, Inc. pumped water from the excavation on May 31, 1991. Water sample D-19 was obtained after approximately 40 gallons were pumped from the excavation. Fuel hydrocarbons were not detected in water sample D-19. Chemical analytical results for water samples D-15 and D-19 are presented in Appendix B. DIESEL UST EXCAVATION NO. 2 Minor evidence of pitting and rusting was observed on the 10,000 -gallon diesel UST during removal operations. No petroleum staining was apparent on the soils beneath the tank. No holes were observed in the UST during the tank removal procedure. The excavation extended to a depth of approximately 10 to 11 feet. Ground water was not encountered in the excavation. Backfill surrounding the tank consisted of approximately 2 feet of silty sand with gravel overlying approximately 6 feet of sand with silt. Native soil consisting of silt with sand was observed in the walls and base of the excavation. 4 Geo./Engineers Five soil samples (D-6 to D-10) were obtained from the initial limits of the excavation and submitted for chemical analysis of fuel hydrocarbons. Observations and field screening in the vicinity of soil sample D-7 indicated the potential presence of gasoline contaminated soils. The owner of the tanks (Segale) indicated that they have only stored diesel in the tanks; however, a previous owner may have stored gasoline in this particular tank. Analytical results indicated fuel hydrocarbons were not detected in soil samples D-6, and D-8 through D-10. Fuel hydrocarbons were detected at concentrations exceeding MTCA cleanup levels in soil sample D-7 obtained from the north wall of the excavation. Additional soil was removed from the north wall and soil sample D-14 was obtained. Soil sample D-14 was also analyzed for BETX. Fuel hydrocarbons and BETX were detected at concentra- tions less than MTCA cleanup levels in D-14. A summary of the field screening and soil chemical analytical results is presented in Table 2. Soil removed from the 10,000 -gallon diesel tank excavation was temporarily stockpiled on-site. WASTE OIL UST EXCAVATION Minor evidence of rusting was observed on the 350 -gallon waste oil UST during tank removal operations. No staining was observed on soils exposed in the lower walls of the excavation or beneath the tank. No holes, pitting or corrosion were observed in the UST prior to excavation. The tank was dented but not ruptured during the removal process. The UST excavation extended to a depth of approximately 6 feet. Ground water was not encountered in the excavation. Backfill surrounding the tank consisted of approximately 2 feet of gravel and sand overlying approximately 4 feet of sand with silt. Native soil consisting of grey silt with varying amounts of fine to medium sand was observed in the walls and bottom of the excavation. Five soil samples (W0-1 through WO -5) were obtained from the initial limits of the waste oil tank excavation and analyzed for TPH (total petroleum hydrocarbons) by EPA Method 418.1. TPH was detected at concentra- tions greater than MTCA cleanup levels in the soil samples obtained from the east wall (W0-2), north wall (WO -3), and west wall (WO -4) of the excavation. TPH was detected at concentrations less than MTCA cleanup levels in soil samples obtained from the south wall (WO -5) and base (W0-1) of the excavation. Additional soil was removed from the west and east walls of the Geo Engineers excavation and soil samples WO -6 and WO -7 were obtained. TPH was detected at concentrations less than MTCA cleanup levels in soil samples W0-6 and W0-7. The north wall of the waste oil excavation was removed during the excavation of the heating oil tank. Soil sample WO -1 was also analyzed for volatile organic compounds by EPA Methods 8010 and 8020, total metal (chromium, copper, lead and zinc) by EPA Method 6010 and PCBs (polychlorinated biphenyls) by Method 8080. Volatile organic compounds, total metals and PCBs either were not detected or were detected at concentrations less than MTCA cleanup levels in soil sample WO -1. Laboratory results of soil samples obtained from the waste oil excavation are summarized in Table 3. Soil removed from the waste oil tank excavation was temporarily stockpiled on-site. HEATING OIL UST EXCAVATION A GeoEngineers representative did not observed the removal of the 500 -gallon heating oil UST. The UST was reported to be in good condition with no apparent holes according to a M.A. Segale representative. The UST excavation extended to a depth of approximately 6 feet. Ground water was not encountered in the excavation. Backfill surrounding the tank consisted of approximately 2 feet of gravel and sand overlying approximately 4 feet of sand with silt. Native soil consisting of grey silt with varying amounts of sand was observed in the walls and base of the excavation. Four samples (H0-1 through HO -4) were taken from the limits of the heating oil tank excavation and analyzed for TPH. TPH was detected at concentrations less than MTCA cleanup levels in the soil samples. A summary of the chemical analytical data is presented in Table 4. Soil removed from the heating oil tank excavation was temporarily stockpiled on-site. SOIL. DISPOSAL GENERAL A total of 310 y3 (cubic yards) of soil was removed from the three UST excavations and stored on-site in three soil stockpiles. Fourteen composite soil samples were obtained from the soil stockpiles for chemical analyses of one or more of the following compounds: BETX, fuel hydrocarbons, TPH, TCLP metals and PCBs. A summary of soil chemical analytical data is shown in Table 5. Laboratory data sheets are presented in Appendix B. 6 SGeoEngineers Composite soil samples were obtained from the three soil stockpiles to segregate clean soil from contaminated soil. Chemical analytical data indicated that concentrations of BETX and/or fuel hydrocarbons were less than MTCA cleanup levels in soil samples SP -1-1, SP -1-2, SP -2-2, SP -2-5, SP -3-2 and SP -3-3 obtained from diesel UST soil stockpiles. Approximately 180 y3 of clean soil was separated from the diesel soil stockpiles based on the chemical analytical results. Fuel hydrocarbons and/or TPH were detected at concentrations greater than MTCA cleanup levels in the remaining soil samples obtained from diesel soil stockpiles and in soil samples SP -4-4 and SP -4-1/2 obtained from the heating/waste oil soil stockpile (Table 5). Composite soil samples (SP -4-1, SP -4-2 and SP -4-3) were obtained from the heating/waste oil soil stockpile and submitted for chemical analyses of volatile organic compounds and PCBs. Trichloroethene was detected at a concentrations greater than MTCA cleanup levels in soil sample SP -4-1. The remaining volatile organic compounds either were not detected or were detected at concentrations less than MTCA cleanup levels in soil sample SP -4-1. Volatile organic compounds either were not detected or were detected at concentrations less than MTCA cleanup levels in soil sample SP -4-2. PCBs were not detected in soil sample SP -4-3. Composite soil samples SP -4-1 and SP -4-2 were combined by the analytical laboratory and the resulting composite soil sample SP -4-1/2 was analyzed for TCLP metals by EPA Method 6010 and 7471 (for mercury). TCLP metals either were not detected or were detected at concentrations less than MTCA cleanup levels in SP -4-1/2. GeoEngineers requested written permission from Rich Mullen of Parametrix, Inc. on behalf of Segale for disposal of the remaining 130 y3 contaminated soil at the Olympic View Landfill in Kitsap County. A copy of our letter is included in Appendix C. Laboratory reports which were attached to the original letter are included in Appendix B. Approximately 140 y3 of soil were transported to Olympic View Landfill on August 27, 1991.. CONCLUSIONS Based on the results of our field observations and analytical testing, it is our opinion that actions to mitigate subsurface petroleum -related soil contamination in the vicinity of the former diesel, heating and waste oil USTs at the M. A. Segale Asphalt Plant located in Tukwila, Washington have 7 • Geo Engineers been completed successfully. The resulting excavations were backfilled with clean imported fill soil. Laboratory analysis of soil samples obtained at the final limits of the excavations indicate that the concentrations of petroleum -related compounds are less than MTCA Method A cleanup levels.

The primary function of the company is to manufacture and sell fluid applied rubber coatings for use as an architectural waterproofing membrane. The building construction, including the lower exterior office is of 6" concrete tilt -up walls. The production area consists of 5 bays, two of which are explosion proof manufacturing areas and the remaining 3 are warehousing areas. The original construction in 1968 was 13,700 square feet of warehouse and manufacturing in bays #1, #2 and #3 along with 6,220 square feet of office area. Bay #4, with 8,175 square feet was added in 1972. In 1984, Bay #5 was constructed with a square footage of 7,739 square feet along with a second level wood framed office area of 6,160 square feet. All areas are fire protected with a sprinkler system. Bay #1 is utilized for the storage of finished or manufactured goods. Bay #2 is used for storage of raw materials, packaging and non-flammable finished goods. Bays #3 and #4 are production bays with a limited amount of storage in the larger Bay #4. Bay #5 is a raw materials warehouse dedicated to non-flammable materials; largely packaging and empty containers. In 1968, a tank farm with eleven tanks was installed having a total capacity of 56,000 gallons. These tanks are used for flammable solvents. In 1972, three additional tanks were installed with a total capacity of 25,000 gallons. These latter three tanks are used largely for resins, some of which contain solvent. A combination of factors have reduced the requirement of storage for solvents. Among these factors are: changing technology utilizing high solids or 100% solids coating, water based latex coatings, and increasing regulation nationally on the amount of solvent that can be evaporated into the atmosphere. Primary among these regulations is the California Air Resources Board Regulations for Volatile Organic Content of architectural coatings. Gaco Western's office area includes accounting, purchasing, and general offices on the lower level and administrative sales offices on the upper level. P.O.
