This letter report has been prepared based on our discussions with representatives of MLA Engineering, PLLC; data collected during our previous observation of excavations that were conducted in the vicinity of the project site; our familiarity with geologic conditions within the vicinity of the project site; and our experience on similar projects. Authorization to provide the geotechnical engineering services described herein was provided by Mr. Chris Keuss of the Port on October 31, 2007. PROJECT BACKGROUND Buildings Number 4 and 5 at the Harbor Square complex in Edmonds, Washington have experienced differential settlement. At Building Number 4 (180 West Dayton Street), the differential settlement has caused cracks to form in the concrete tilt -up panels that comprise the west side of this building. At Building Number 5 (170 West Dayton Street), the northeast corner of the building has settled at a rate greater than the remainder of the building. We understand that a total of 12 helical piles will be used to stabilize the shallow foundations that support these two buildings. We also understand that the helical piles, each of which will have a minimum axial capacity of 20 kips and a minimum length of 20 feet (ft), will be contractor designed. SITE HISTORY In 1994, GeoEngineers, Inc., on behalf of Union Oil Company of California (Unocal), developed a historical summary for the area that is now occupied by the Harbor Square complex (GeoEngineers 1994). According to the 1994 report, some of the activities conducted at the site include,the following: ENVIRONMENTAL ( GEOTECHNICAL I NATURAL RESOURCES 130 2nd Avenue South • Edmonds, WA 98020 • (425) 77&M7 • fax (425) 778-6409 • wwwJandat inc.com SEATTLE • SPOKANE • TACOMA • PORTLAND • 1924 to 1940s: Unocal operated a fuel storage and distribution facility (Union Oil Dayton Street Depot) in the northern portion of the site. In later years, Unocal leased portions of the site to several entities. • 1948 to 1963: General American Transportation Company (GATX) operated a rail car cleaning and maintenance facility in the northern and western portions of the site. • 1958 to 1968: Joplin Paving Company operated an asphalt batch plant in the eastern portion of the site. Lease provisions included disposal of asphalt and hot mix residuals outside of the lease area but within current site boundaries. • Early 1960s: The eastern and southern portions of the site were filled with dredged sand and gravel from the construction of the Port marina and possibly other sources. • 1968 to 1978: Site use unknown. • 1978: The Port purchased the property and leased it to Harbor Square Associates (HSA). • 1983: The Port leased the property to HSA and HSA began phased development of the existing Harbor Square complex. Several improvements/expansions have occurred since the initial development, notably to the hotel and health and tennis club in the eastern portion of the site. Between 2004 and 2005, the Port conducted remedial activities at three areas within the Harbor Square complex located near the 120, 170, 180, and 190 West Dayton Street buildings. The remedial activities were conducted to address the removal and disposal of petroleum contaminated soils and debris. In areas of the site where the impacted soil extends beneath the above -described buildings, the impacted soil was left in place directly beneath and immediately adjacent to the building footprints. . GEOLOGIC SETTING General geologic information for the project area was obtained from the DRAFT Composite Geologic Map of the Sno-King Area, Central Puget Lowland, Washington (Booth et al. 2004), published by the Seattle -Area Geologic Mapping Project (SGMP) at the University of Washington and the United States Geological Survey (USGS). According to this geologic map, near -surface deposits at the project site consist of wetland deposits. Further east of the project site, near -surface soils consist of pre -Frasier deposits. Soils defined as pre -Frasier deposits generally exhibit relatively high shear strength as a result of being glacially over -ridden. South of the project site, an extensive wetland area is present (locally called the Union Oil Marsh). We are aware from our other work in the Port of Edmonds area that the wetland area was originally much larger and that fill has been placed in most of the Port of Edmonds area to create the current topography. Although the near surface soils in the project area are mapped as wetland deposits, 12/13/07 \\Edmdata\projects\173\030\FlIeRm1Rk9dgs 4 and 5 Geo t.tr.doc LANDAU ASSOCIATES 2 fill associated with the previous filling of the wetlands to establish existing site grades is present across the site. ANTICIPATED SUBSURFACE SOIL CONDITIONS Based on our knowledge of subsurface conditions in other nearby areas of the Port of Edmonds and the results of field exploration programs and remedial activities that we previously observed in the project area, the area in the vicinity of Buildings Number 4 and 5 is interpreted to be underlain by a sequence of fill, beach/wetland deposits, and pre-Vashon age glacial outwash deposits. The fill in the project area is anticipated to generally consist of brown, loose to medium dense, gravelly, fine to coarse sand. In the vicinity of Buildings Number 4 and 5, we estimate that the fill extends to depths of about 8 to 10 ft below the ground surface (BGS). From our previous experience with fill in the Port of Edmonds area, we know that in areas the fill contains debris, including, but not limited to, numerous railroad ties, other assorted wood debris, large pieces of asphalt and concrete, sections of metal and concrete pipes (some containing petroleum product), automobile parts, construction rubble, and miscellaneous refuse. Beach/wetland deposits, generally consisting of gray, medium dense, fine to medium sand with occasional gravel and wood fragments, are anticipated beneath the fill. In areas, the beach/wetland deposits contain a layer of peat that is up to about 3 ft thick. In the vicinity of Buildings Number 4 and 5, we estimate that the beach/wetland deposits extend to depths of about 13 to 15 ft BGS. Pre-Vashon glacial outwash deposits are expected beneath the beach/wetland deposits. The glacial outwash deposits in the project area generally consist of very dense, gray, gravelly, fine to coarse sand; fine to coarse sand with gravel; and fine to medium sand. Borings that we previously completed in the Port of Edmonds area, some of which have extended up to about 40 ft BGS, did not fully penetrate the glacial outwash deposits. ANTICIPATED GROUNDWATER CONDITIONS Based on our knowledge of subsurface conditions in other nearby areas of the Port of Edmonds and the results of field exploration programs and remedial activities that we previously observed in the project area, we anticipate that the depth to groundwater in the vicinity of Buildings Number 4 and 5 is generally about 7 to 8 ft BGS; however, in certain areas of the site and/or during certain times of the year, the groundwater table may be located within about 2 ft of the ground surface. Furthermore, it is anticipated that groundwater conditions will vary depending on local subsurface conditions, the weather, tidal fluctuations, and other factors. 12/13/07 \\Edmdata\projects\173\030\Fi1eRm\R\81dgs 4 and 5 Geo Ltr.doc LANDAU AssocIATES 3 ENVIRONMENTAL CONSIDERATIONS It is possible that petroleum contaminated soils and debris that were not previously cleaned up could be encountered during construction of the proposed project. Consequently, the contractor should exercise due caution when excavating existing soil to minimize the health hazard posed to all onsite project participants. LIQUEFACTION POTENTIAL The Pacific Northwest is seismically active and the project site could be subject to ground shaking from a moderate to major earthquake. Based on Landau Associates' site investigation for a nearby project (Landau Associates 1995), the near -surface soil at the site are considered to be potentially liquefiable. Liquefaction is defined as a significant rise in pore water pressure within a saturated soil mass caused by earthquake -induced cyclic shaking. The shear strength of liquefiable soil is reduced during large and/or long -duration earthquakes as the soil consistency approaches that of a semi -solid slurry, which can result in reduction of foundation support and ground settlement. Deposits of loose, granular soil below the water table are most susceptible to liquefaction. Our assessment of liquefaction potential at this site considered the results of other borings within the Port of Edmonds area that have encountered the fill and beach/wetland deposits. The available groundwater information suggests that the base of the fill and the underlying beach/wetland deposits are below the groundwater table. The results of the previous borings within the Port of Edmonds area indicate that the density of the soil at the base of the fill and the beach deposits vary from loose to medium dense. Previous liquefaction analyses for nearby projects (Landau Associates 2007) indicate that looser portions of the fill and beach/wetland deposits below the groundwater table could potentially be subject to liquefaction during a large seismic event, while other portions may be dense enough to resist liquefaction. In our opinion, a sufficient thickness of soil is present above the water table to preclude the potential for shallow foundation failure due to liquefaction. However, this situation could lead to localized zones of liquefaction during a large seismic event, which could result in differential ground settlement. FOUNDATION SUPPORT RECOMMENDATIONS Helical piles may be used to stabilize and lift the portions of the foundations of Buildings Number 4 and 5 that have settled. The installation process is accomplished by securing special brackets to the existing concrete foundation and then screwing a steel pile into the soil through each bracket. If necessary, hydraulic jacks can be used at each bracket to lift the existing foundation back into place. 12/13/07 \\Edmdata\projects\173\030\Fi1eRm\R8dgs 4 and 5 Geo Urdoc LANDAU ASSOCIATES 4 Helical piles can be installed in limited access/low headroom conditions and do not require excavation of soil or removal and disposal of spoils. Helical piles are typically contractor designed using established installation torque to pile capacity relationships. For this project, the design may assume the following soil profile in the following table for the purpose of designing helical plies. Depth (ft) Geologic Unit Density Soil Description 0 to 10 Fill Loose to Medium Dense Gravelly, fine to coarse sand (with debris) Fine to medium sand with occasional 10 to 15 BeachNVeband Deposits Medium Dense gravel and wood fragments, and peat layers up to about 3 ft thick Gravelly, fine to coarse sand; fine to 15 to 40 ft Glacial Outwash Very Dense coarse sand with gravel; and fine to medium sand It should be recognized that the actual subsurface conditions at the project site may be different from those described above. This is particularly the case because project -specific borings were not performed. As a result, the actual lengths of the helical piles may vary depending on the actual subsurface conditions encountered during construction. We therefore recommend structuring the contract documents to allow for pile length adjustments. CONSTRUCTABILITY ISSUES The contractor should be made aware that previous excavations in the vicinity of Buildings Number 4 and 5 encountered numerous railroad ties, other assorted wood debris, large pieces of asphalt and concrete, sections of metal and concrete pipes (some containing petroleum product), automobile parts, construction rubble, and miscellaneous refuse. As a result, the contractor should be prepared for the possibility of encountering obstructions during the installation of the helical piles. If obstructions are encountered during the installation of helical piles, the contractor should either remove the obstruction or modify the location of the helical pile. If it is necessary to modify the location of a helical pile to avoid an obstruction, the project structural engineer should identify the new location. In addition, we recommend adding language to the contract documents that discusses how obstructions, if encountered, will be handled and paid for. REVIEW OF DOCUMENTS AND CONSTRUCTION OBSERVATIONS We recommend that Landau Associates be retained to review the geotechnical-related portions of the project plans and specifications to determine if they are consistent with the recommendations 12/13/07\\Edmdata\proiects\173\030\ReRm\R0dgs 4 and 5 Geo Ltr.doc LANDAU ASSOCIATES 5 presented in this report. We also recommend that monitoring, testing, and consultation be provided during construction to confirm that the conditions encountered are consistent with those anticipated, to provide expedient recommendations should conditions be revealed during construction that differ from those anticipated, and to evaluate whether geotechnical-related construction activities comply with project plans and specifications, and the recommendations contained in this letter report. USE OF THIS LETTER REPORT Landau Associates prepared this letter report for the exclusive use of the Port of Edmonds and their design consultants for specific application to the design of the proposed Harbor Square Buildings Number 4 and 5 Stabilization and Repair project in Edmonds, Washington. Use of this letter report by others or for another project is at the user's sole risk. Within the limitations of scope, schedule, and budget, our services have been conducted in accordance with generally accepted practices of the geotechnical engineering profession; no other warranty, express or implied, is made as to the professional advice included in this letter report. The conclusions and recommendations contained in this letter report are based in part upon the subsurface data we obtained from explorations completed for nearby projects and subsurface information we gathered when the Port conducted remedial activities in the vicinity of Buildings Number 4 and 5. There may be some variation in subsurface soil and groundwater conditions at the project site, and the nature and extent of the variations may not become evident until construction. Accordingly, a contingency for unanticipated conditions should be included in the construction budget and schedule. If variations in subsurface conditions are encountered during construction, Landau Associates should be notified for review of the recommendations of this letter report and revision of such if necessary. If there is a substantial lapse of time between submission of this letter report and the start of construction, or if conditions change due to construction operations at or adjacent to the project site, we recommend that we review this letter report to determine the applicability of the conclusions and recommendations contained herein. 12/13/07 1\Edmdata\projecis\173\030\FileRm\R\&dgs 4 and 5 Geo lh.doc LANDAU AssoctATEs 6 We appreciate the opportunity to provide geotechnical services on this project and look forward to assisting you during the construction phase of the project.

The site is located in Edmonds, Washington (Figure 1). ' During the period from August 2004 to February 2005, Landau Associates conducted a remedial action consisting of the excavation and offsite removal of petroleum -impacted soils, debris, and free - phase petroleum hydrocarbons (Landau Associates 2005). Petroleum -impacted soils, debris, and free - phase petroleum hydrocarbons were observed in the sidewall of the excavation that bordered the ' Edmonds Marsh at a depth of approximately 7 to 8 ft below ground surface (BGS). In addition, petroleum -impacted soil was observed in the sidewall at the southeastern extent of Remediation Area I at a depth of approximately 6 ft BGS. Further excavation in to the Edmonds Marsh was not conducted due to the potential for water in the marsh to drain into the excavation and further excavation to the southeast of Remediation Area I was not conducted to limit disruptions to nearby businesses. ' Landau Associates plans to conduct additional subsurface assessment to determine the extent to 1 �r 1 1 which the petroleum impacts and free -phase petroleum hydrocarbons at the southern border of Remediation Area I extend out into the marsh and to attempt to determine the nature and extent of subsurface petroleum impacts to the southeast of Remediation Area I. The assessment is expected to include the advancement of approximately six soil borings in the marsh. Figure 2 shows potential soil boring locations that are located on the Port of Edmonds (Port) property. Site access has not been granted by the City of Edmonds (City) to conduct additional assessment on property owned by the City. Soil boring locations will be limited to the "dry" areas of the marsh. Actual soil boring locations and number of samples may be adjusted, based on field conditions (i.e., surface water elevation in the marsh and soil saturation) and the extent of petroleum impacts (if encountered). It is expected that a minimum of 5 and a maximum of 10 samples will be collected for laboratory analysis. Further assessment (in the form of the collection of additional samples) may be needed if 10 samples are not sufficient to delineate the extent of the free product. If more than 10 samples are required to assess the extent of free product in the marsh, these samples may be collected during a separate sampling event after the Port reaches an agreement with the Washington State Department of Ecology to determine who should be responsible for collecting additional data in the marsh and, if necessary, after access is granted by the City to conduct assessment activities on City property. The additional assessment to the southeast of Remediation Area I will be conducted by completing a series of "test trenches" for the purpose of collecting soil samples (Figure 3). Test trenches 07/25/05 SAWPR0M173\025\015\Edmonds Marsh_SAP-Final.doc 1-1 LANDAu AssoCIATES are being used instead of soil borings due to the somewhat discontinuous nature of the petroleum impacts observed during the August 2004 to February 2005 remedial action. Based on the conditions observed during trenching activities -and analytical results of verification soil samples, excavation of the test trench assessment area may immediately follow trenching activities. The assessment activities will occur after necessary permits are acquired and the marsh is sufficiently dry to allow for personnel and sampling equipment to enter the area. The remainder of this document presents sample collection procedures (Section 2.0), field procedures (Section 3.0), a tentative schedule (Section 4.0), and references (Section 5.0). The project Health and Safety Plan is presented as Appendix A. 0725/05 S:\WPROQ173\02Wl5\EdrriondsMarsh_SAP-Final.doc 1-2 LANDAu ASSOCIATES 7 11 11 0 17, 2.0 SAMPLE LOCATIONS AND ANALYSIS Proposed sample collection locations are shown on Figure 2 (Edmonds Marsh) and on Figure 3 (southeast of Remediation Area I). In conjunction with the preparation of the SAP, Landau Associates will schedule a private utility locate contractor for the site to identify potential subsurface utilities that may be located within the planned assessment area. Following the location of subsurface utilities, Landau Associates will identify sampling locations in the Edmonds Marsh using survey stakes and test trenches located southeast of Remediation Area I using spray paint. Sample locations in the test trenches southeast of Remediation Area I will be determined in the field. The number of samples to be collected and the chemical analyses to be performed on each sample are described below. 2.1 EXPLORATION LOCATION AND SAMPLE COLLECTION 2.1.1 EDMONDS MARSH If possible, a hand auger will be used to collect soil samples for laboratory analysis. If soil samples cannot effectively be collected using a hand auger (i.e., too great of a vacuum is induced preventing the successful extraction of the hand auger from the marsh soils), then a small direct -push (i.e., jackhammer) unit will be used to drive direct -push probe rods into the soil. Soil borings will extend to approximately 3 to 10 ft BGS, depending on subsurface conditions encountered in the field. The final locations of the borings may be adjusted in the field, based on conditions in the marsh. The advancement of all borings will be monitored and recorded by a Landau Associates field representative. A record of the soil and groundwater conditions will be maintained in a boring log. The boring log will show sampling depths, sampling methods, sample recoveries, soil types, stratifications, any evidence of contamination observed during drilling, and other information pertinent to the investigation. Each boring log will also identify the name of the drilling company and operator(s), the type of drilling equipment, starting and finishing dates for drilling, boring number, and boring location. Soil types will be described in accordance with the Unified Soil Classification System (USCS). Field analysis of volatile organic compounds (VOCs) in the composite samples will be completed using a photoionization detector (PID). We anticipate that one soil sample from each boring will be selected for laboratory analysis, based on field screening results and physical evidence. Boring locations will be surveyed to establish their horizontal position using differential global positioning system (DGPS) equipment. 1 07/25/05 S:\WPR0C073\025\015\Edmonds Marsh SAP-Final.doc 2-1 LANDAu AssocIATES 2.1.2 SOUTHEAST OF REMEDIATION AREA I Landau Associates personnel will collect soil samples from the sidewalls and base of test trenches. Test trenches will extend to approximately 8 to 12 ft BGS, depending on subsurface conditions encountered in the field. The final locations of the trenches may be adjusted in the field. The excavation of all test trenches will be monitored and recorded by- a Landau Associates field representative. All field activities, including soil removal and soil sampling, will be documented and managed by project oversight personnel in appropriate forms and in field notebooks. A record of the soil and groundwater conditions will be maintained in field notebooks. The field notebook will show sampling depths, soil types, stratifications, any evidence of contamination observed during drilling, and other information pertinent to the investigation. Soil types will be described in accordance with the USCS. Field analysis of VOCs in the soil samples will be completed using a PID. In addition, stockpile characterization samples will be collected from the excavated soil stockpiles. Stockpile characterization samples will be collected to verify that petroleum hydrocarbon concentrations are in the excavated soil, if excavated soil is to be disposed off site, and to justify disposal methods for the impacted material. 2.2 ANALYTICAL TESTING METHODS For purposes of this SAP, we have anticipated that a maximum of 15 samples will be collected from the Edmonds Marsh investigation and 30 samples will be collected from the test trenches southeast of Remediation Area I. Samples will be analyzed by the laboratory for gasoline -range total petroleum hydrocarbons (TPH-G) using Method NWTPH-Gx; benzene, toluene, ethylbenzene, and total xylenes (BTEX) using U.S. Environmental Protection Agency (EPA) Method 8021; and diesel- and lube oil -range total petroleum hydrocarbons (TPH-D and TPH-O) using Method NWTPH-Dx. A sample collection and analysis summary is presented in Table 1. Samples will be delivered to CCI Laboratories located in Everett, Washington for laboratory analysis. 0725/05 S:\WPROC\173\025\015\Edmonds Marsh_SAP-RnW.doc 2-2 LANDAU ASSOCIATES ' 1 3.0 FIELD PROCEDURES ' 3.1 SAMPLE DESIGNATION Designations of samples collected from exploration locations in the Edmonds Marsh will be preceded with the prefix "HA" for hand auger or "DP" for direct -push, and numerically sequenced. Designations of samples collected from each hand auger exploration will receive a suffix denoting the top ' of the 1-ft depth interval from which it was collected. For example, HA-3-7 will represent the sample collected from hand auger exploration number 3 beginning at a depth of 7 to 8 ft BGS. Samples collected from each direct -push exploration will receive a suffix denoting the top of the 2-ft depth interval from which it was collected. For example, DP-2-4 will represent the sample collected from direct -push ' exploration number 2 beginning at a depth of 4 to 6 ft BGS. Samples collected from a test trench will be identified using the following naming convention: Example: LAI-SW3-TT1-4 LAI: Landau Associates, Inc. I SW3: Sample is the 3rd sidewall sample collected in the test trench ("Floor" similarly used for samples collected from the base of the trench). I TT1: Sample collected from test trench 1. 4: The depth (in feet) at which the sample was collected. 3.2 SAMPLING PROCEDURES ' Samples will be selected for chemical analyses based on field screening results (i.e., PID, olfactory, and visual observation). If field screening results indicate no obvious signs of contamination, ' then the sample interval directly above the water table may be selected for analysis. Samples will be collected directly from a hand auger head, a direct -push sample sleeve, or a backhoe bucket using a decontaminated stainless steel spoon. The samples will then be placed directly into laboratory -supplied containers. Each jar will be labeled as described in Section 3.1 of this report. The specific sample ' collection equipment is described below: 3.2.1 EDMONDS MARSH The hand augers to be used at the site will consist of a 3/a-inch diameter metal rod with an open- ended metal cylinder auger head attached to the bottom and a metal handle attached to the top. The auger will be advanced or extracted by rotating the handle clockwise and counterclockwise, respectively. The direct -push samplers to be used at the site will consist of an outer cylindrical steel casing (approximately 1 0725/05 S:\WPROC\173\025\015\Edmonds Marsh_SAP-Final.doc 3-1 LANDAU ASSOCIATES 2 inches in diameter) with a dedicated polyethylene sample sleeve inside. The sampler will be advanced into soils using a jackhammer or roto-hammer and extracted with a small, portable hydraulic jack. The footprint of the jack will be approximately 1.5 ft by 1.5 ft. Supports (i.e., 2-inch by 4-inch lumber) will be used to prevent the jack from sinking into the marsh while the sampler section is being retrieved. The sleeve will be extracted from the sampler once the sampler section is retrieved from the boring. The contents of the hand auger head or direct -push sample sleeve will be field -screened for VOCs using a PID. The resulting PID reading, soil descriptions, and drilling observations will be recorded by the Landau Associates field personnel on a boring log. 3.2.2 SOUTHEAST OF REMEDIATION AREA I Soil samples will be collected from approximately 0 to 6 inches into the sidewall and base at each sample location using a stainless steel spoon or hand auger, or from the excavator bucket when gaining access to sample locations could be a personal safety hazard. If soil is collected from the excavator bucket, care will be taken to collect the sample from the least disturbed soil not in direct contact with the excavator bucket. Approximately one soil sample will be collected per every 50 linear ft of sidewall and one at the base of each trench. Actual sample locations may vary depending on field conditions encountered. The final sample collection locations will be recorded on a map prepared by personnel collecting the soil samples. Samples will be field screened for VOCs using a PID. The resulting PID reading, soil descriptions, and drilling observations will be recorded by the Landau Associates field personnel in a field notebook. A City active water supply main extends southeast to northwest through the investigation area that -the test trenches will be excavated, as seen on Figure 3. Excavation of test trenches near the water main may become a safety hazard due to the high pressure in the water main. During the August 2004 to February 2005 remedial action, construction personnel installed isolation valves at two points along the water main to isolate a portion of the water main. Prior to test trenching, this portion of the water main will be isolated to allow for future excavation without disruption of the potable water supply. 3.3 GLOBAL POSITIONING SURVEY Sample locations will be surveyed to establish their horizontal position using the Global Positioning System. 0725/05 SAWPROM171025\015\Edmonds Marsh SAP•Final.doc 3-2 LANDAU ASSOCIATES 3.4 SAMPLE LABELING, SHIPPING, AND CHAIN -OF -CUSTODY ' Sample container labels will be completed immediately before or immediately following sample collection. Container labels will include the following information: ' • Project name • Project number ' • Sample identification • Initials of the person collecting the sample • Date and time of collection • Analysis requested. Samples will be transported to the designated analytical laboratory using the following procedures: ' • Samples will be placed on ice in a sealed cooler immediately after collection • Each sample container will be individually packed in bubble wrap when placed in the cooler ' • The samples will be sent by courier to the analytical laboratory Y b Landau Associates • All samples submitted for analysis will be accompanied by a Chain -of -Custody form. ' 3.5 EQUIPMENT DECONTAMINATION ' 3.5.1 EDMONDS MARSH All sampling equipment will be fully decontaminated before use and in between sample collections. If direct -push drilling methods are necessary, hydrocarbon absorbent drip pads will -be placed ' in areas where there could be potential drips of hydrocarbons. Landau Associates and drilling personnel will have a spill kit at the site in the event of a discharge of hydraulic fluid, oil, or fuel. Sampling equipment (spoons and bowls) will be placed into 5-gal buckets directly after use. These buckets will be transported out -of the marsh by Landau Associates personnel where wet ' decontamination methods will be used to minimize the possibility of cross -contamination. Down -the - hole drilling equipment (augers or probes with soil sampling sleeves) will also be transported out of the ' marsh and decontaminated using wet decontamination methods prior to each sample interval. Wet decontamination procedures are as follows: ' • Wash equipment with Alconox/tap water solution. (If heavy -oil free product is encountered, an initial hexane/methanol rinse may be used to remove the residuals from the equipment.) ' 07/25/05 SAWPROO\77M025\015\Edmonds Marsh_SAP-Final.doc 3-3 LANDAU ASSOCIATES • Rinse with tap water 0 Rinse with de -ionized water • Repeat entire procedure or any parts of the procedure as necessary • Disposable gloves will be changed between each sampling location. 3.5.2 AREA SOUTHEAST OF REMEDIATION AREA I Prior to commencement of trenching activities, work zones will be established to designate areas for specific tasks. The work zones will include: the exclusion zone, the contamination reduction zone (which encompasses an equipment decontamination zone and a personnel decontamination zone), and the support zone. Preliminary identification of these various zones is indicated on Figure 3. The exclusion zone will include the area encompassing the proposed test trenches and the contamination reduction zone, as indicated on Figure 3. Only site personnel with proper training and equipped in appropriate personal protective equipment will be permitted to enter the exclusion zone after reviewing and signing the health and safety plan (HASP) prepared by Landau Associates (Appendix A). The exclusion zone will be demarcated with caution tape during trenching activities. The support zone will consist of the remainder of the site used for ingress and egress for the site and will remain accessible to the public during the removal action. 3.6 RESIDUALS MANAGEMENT Soil and water generated during the sample collection and any decontamination processes will be contained in 5-gal buckets then transferred to 55-gal drums. Drums will be temporarily stored on Port property pending analytical results. Landau Associates will arrange for the disposal of generated waste water and soil. Disposable clothing and equipment will be placed in plastic bags and disposed as solid waste in an appropriate solid waste facility. Residual soils will be characterized by the analytical results of soil samples. 0725/05 SAWPR=173\025\015\Edmonds Marsh SAP-Final.doo 3-4 LANDAU ASSOCIATES I 4.0 SCHEDULE Sampling activities in the Edmonds Marsh and trenching activities in the area southeast of Remediation Area I are scheduled to occur, if site conditions allow, in summer 2005; however, this schedule is subject to change based on the weather. Potential flooding in the marsh could prevent successful access to the marsh and recovery of soil samples. Additionally, a high groundwater table in the surrounding subsurface could cause significant difficulties to excavating test trenches and to the recovery of soil samples. 0725/05 SAWPROM171025015\Edmonds Marsh SAP-Final.doc 4-1 LANDAU ASSOCIATES 5.0 REFERENCE Landau Associates. 2005.
