W., SUITE 200 LYNNWOOD, WA 98036-5957 at TEL.425-774-0106 FAX.425-774-2714 E-MAIL hwa@hongwest.com MAR 181999 CITY OF RLoVTON Engineering Dept. This report presents the results of the HWA GeoSciences Inc. (HWA) soil/sediment sampling at the SW 27`h Street Culvert Replacement project in Renton, Washington. INTRODUCTION King plans to replace two existing arch culverts at SW 27 h Street with a box culvert. This work will involve the removal of approximately 50 cubic yards of soil and sediment during construction. Soil and sediment contamination has been documented in other nearby culverts. SCOPE OF WORK The scope of work for the environmental site investigation was designed to investigate the potential presence of soil or sediment contamination that may present liability issues, health and safety concerns during construction, delay or affect construction, or require additional investigation or remediation costs. The scope of work is summarized below: • Collect one composite sample of soil/sediment to be removed • Submit sample to analytical laboratory for analysis • Prepare letter report with results and recommendations for disposal • Provide assistance with construction bid documents for contaminated soil/sediment disposal Sampling HWA collected four grab samples, two at each end (upstream and downstream) of the culverts, and homogenized these into one composite sample, S-1. Figure 1 shows the location of the site. Figure 2 shows the sample locations. HWA uses a stainless steel GEOLOGY GEOENVIRONMENTAL SERVICES HYDROGEOLOGY GEOTECHNICAL ENGINEERING TESTING & INSPECTION March 15, 1999 HWA Project No. 98032-300 hand auger to collect the samples. The samples were collected at depths of 0-12 inches below the sediment surface, under two to four feet of flowing water. Samples were composited in a stainless steel bowl prior to placing in precleaned, labeled glass jars. All sampling and compositing equipment was decontaminated prior to use with detergent solution, potable water, and deionized water. The HWA geologist logged the samples and recorded field observations regarding the presence of contamination or other notable characteristics. Samples were also field screened for organic vapors by headspace analysis using a photoionization detector (PID). The samples consisted of wet, dark brown, sandy silt with organics. No PID readings above background, were recorded, and no other indications of contamination were noted. Samples were submitted to OnSite Environmental, Inc., Redmond, Washington, for the following analyses: Analysis Method ----------------------------------------------------------------------------------------------- Total Petroleum Hydrocarbons (TPH) WTPH-D extended Volatile organic compounds (VOCs) SW846 #8260 Semivolatile organic compounds (SVOCs) SW846 #8270 Pesticides, Polychlorinated biphenyls (PCBs) SW846 #8081 Priority pollutant Metals: SW846 #6000/7000 series (antimony, arsenic, beryllium, cadmium, chromium, copper, lead, mercury, nickel, selenium, silver, thallium, and zinc) Results Table 1 summarizes the analytical results.

Bold indicates exceedance of Method A or B cleanup level * No other method -listed SVOCs or metals were detected above reporting limits (see Appendix A for list of compounds analyzed) DISCUSSION Sample results were compared with Model Toxics Control Act (MTCA) Cleanup Regulation soil cleanup levels to evaluate disposal options for excavated materials. Analysis of compliance with sediment standards was not part of this scope of work. The sample collected does not appear to exceed any Dangerous Waste Criteria for the compounds analyzed. The composite sample collected contained several SVOCs and one metal (cadmium) above MTCA method A and B cleanup levels. The SVOCs detected above MTCA cleanup levels are carcinogenic polynuclear aromatic hydrocarbons (cPAHs). TPH-as-Oil in one or more of the individual grab samples may also have 98032rpl.DOC 3 HWA GEOSCIENCES INC. March 15, 1999 HWA Project No. 98032-300 exceeded the Method A soil cleanup level, based on the elevated concentration detected in the composite sample. RECOMMENDATIONS Petroleum, SVOC, and metals contaminated soil or sediment may be encountered during project excavation and earthwork. Construction bid documents (plans and specifications) should include all analytical results and provisions for contaminated soil handling, treatment/disposal, and health and safety requirements. Several treatment and disposal options are available, including: Off -site landfill disposal at a licensed facility Off -site thermal treatment and disposaUrecycling at a licensed facility Thermal treatment may not be suitable for saturated soils, but small volumes are generally accepted at these facilities. Additional sampling during or after excavation to confirm these results and limit the volume requiring treatment or disposal may not be cost effective for the small total anticipated volume to be excavated (50 cubic yards). In addition, disposal options may still be limited for soil with contaminants below clean up levels. MTCA clean up levels are used in this report for reference only, and normally apply to soils being excavated for the purpose of remediation. Criteria for unrestricted use or disposal of soils may be lower than the cleanup levels shown. For example, soils with some contaminant concentrations above detection limits but below cleanup levels should not be used as fill near surface or ground water, and may not be accepted at fill sites. Prospective fill site owners should be notified of the results of this study and any additional testing information available at that time. Reporting Requirements Pursuant to MTCA regulations (Chapter 173-340-300 WAC), the property owner or operator may be required to notify Ecology within 90 days of discovery that an uncontrolled release of a hazardous substance was discovered. This report may be used for reporting purposes.

March 15, 1999 HWA Project No. 98032-300 Health and Safety We recommend that appropriate health and safety measures be taken during excavation or dewatering in areas where contaminated soils or ground water may be present. These measures may include, but are not limited to, preparation of a site specific health and safety plan, air monitoring, protective and decontamination measures, worker training, certification, and medical monitoring. We recommend an industrial hygienist or health and safety specialist be consulted to determine the applicability of these requirements. LIMITATIONS The conclusions expressed by HWA are based solely on material referenced in this report. Observations were made under the conditions stated.

DATA QUALIFIERS AND ABBREVIATIONS A - Due to high sample concentration, the amount spiked is insufficient for meaningful MS/MSD recovery data. B - The analyte indicated was also found in the blank sample. C - The duplicate RPD is outside control limits due to high result variability when analyte concentrations are within five times the quantitation limit. D - Data from 1: dilution. E - The value reported exceeds the quantitation range, and is an estimate. F - Surrogate recovery data is not available due to the high concentration of coeluting target compounds. G - Insufficient sample quantity for duplicate analysis. J - The value reported was below the practical quantitation limit. The value is an estimate. K - Sample duplicate RPD is outside control limits due to sample inhomogeniety. The sample was re - extracted and re -analyzed with similar results. M - Predominantly range hydrocarbons present in the sample. N - Hydrocarbons in the gasoline range (C7-toluene) are present in the sample. O - Hydrocarbons in the heavy oil range (>C24) are present in the sample. P - Hydrocarbons in the diesel range (C12-C24) are present in the sample which are elevating the oil result. Q - The RPD of the results between the two columns is greater than 25. R - Hydrocarbons outside the defined gasoline range are present in the sample; NWTPH-Dx recommended. S - Surrogate recovery data is not available due to the necessary dilution of the sample. T - The sample chromatogram is not similar to a typical U - Matrix Spike/Matrix Spike Duplicate RPD are outside control limits due to matrix effects. V - Matrix Spike/Matrix Spike Duplicate recoveries are outside control limits due to matrix effects. X - Sample underwent silica gel cleanup procedures. Y - Sample underwent acid cleanup procedures. Z - Interferences were present which prevented the quantitation of the analyte below the detection limit reported.
