1.0 INTRODUCTION

1.1 Site DescriptionThe project site is located in a parking lot adjoining 1210 West Marine View Drive in Everett, Washington(the Property). The Property is bordered to the north by several warehouse-style buildings occupied by various companies serving the nearby marina with services including diesel engine maintenance, parts manufacturing, boat sales; to the east by West Marine Drive; to the south by a boat yard; and to the west by a parking lot.

The site is located along the Everett waterfront, east of Port Gardner. The former shoreline was located about 200 feet to the east, and the site and surrounding area were filled over the years to create the current waterfront topography. The site and vicinity have a history of industrial land uses dating back to the 1800s.

The Property consists of a small portion of the North Marina Ameron/Hulbert Site, which is part of the PortofEverett’sWaterfrontPlaceRedevelopment project. The Port has previously completed extensive environmental investigations across the entire North Marina Ameron/Hulbert Site, including on the Property. Based on the results of these studies, the potentially liable parties (Port of Everett, Ameron International, and the Hulbert family) have entered into an Agreed Order with Ecology to clean up the North Marina Ameron/Hulbert Site.

According to a Remedial Investigation/Feasibility Study (RI/FS) prepared by Landau Associates in 2014, contaminants of concern (COC) at the overall North Marina Ameron/Hulbert Site consist of carcinogenic polycyclic aromatic hydrocarbons (cPAH), antimony, arsenic, copper, lead, and total petroleum hydrocarbons (TPH) in soil; and copper, arsenic, TPH, 1-1-dichloroethylene, and bis(2-ethylhexyl)phthalate in groundwater.

1.2 Project Information

The project consists of constructing a new single-bank substation. The proposed configuration of the substation is illustrated on the Site and Exploration Plan, Figure 1. Improvements at the site are expected to include:

• The construction of transmission line dead end towers, a circuit switcher, a neutral reactor, and a 12.5 kV switch.

• A new metal-clad switchgear enclosure and slab and a new slab-supported transformer with a perimeter oil containment slab and associated piping.

• The existing site grade is approximately elevation 14 feet, and the substation yard grade is expected to be approximately 2 feet higher.

• Underground electrical conduits will be installed, as well as below-grade pre-cast concrete vaults;• Stormwater will be collected and routed to existing storm sewers which will direct water off-site.• Access to the substation will be provided by an asphalt-paved driveway at the north.

Construction of the substation will require asphalt removal and subsurface work to construct foundations

for new equipment and installation of utilities. This work may necessitate the removal and off-site disposal of some of the fill soil that underlies the project site, and disposal of construction dewatering effluent.

1.3 Project ObjectivesThe objectives of this project are to characterize the fill soil beneath the project site for potential off-site disposal, to characterize groundwater for potential dewatering activities, and to characterize both soil and groundwater in regard to potential construction worker exposure during earthwork phases of construction.

1.4 Standard of CareThe analytical results within this report are based on samples collected from the indicated locations at the time of sample collection, and should not be construed as a warranty of the subsurface conditions throughout the site or at other times. No environmental investigation can wholly eliminate uncertainty regarding the potential for recognized environmental conditions in connection with a property. This environmental investigation is intended to reduce, but not eliminate, uncertainty regarding the existence of recognized environmental conditions. Within the limitations of scope, schedule and budget for our work, we warrant that our work has been done in accordance with our proposal and generally accepted environmental assessment practices followed in this area at the time the report was prepared. No other warranty, express or implied, is made.

1.5 RelianceThis report has been prepared for the exclusive use of Snohomish County PUD No. 1 and any authorization for use or reliance by any other party (except a governmental entity having jurisdiction over the site) is prohibited without the express written authorization of Snohomish County PUD No. 1 and ZGA.

2.0 METHODOLOGYThis Site Characterization included completion of the following tasks:

1. Advance six direct-push explorations.2. Soil and groundwater sampling.3. Analytical laboratory testing.4. Report preparation, including interpretation of the analytical results relative to cleanup levels

defined in the Model Toxics Control Act (WAC 173-340).

Each of these investigation activities is summarized below.

2.1 Subsurface ExplorationField activities were conducted on April 5, 2017 by Evelyn Conrado, a staff geologist with ZGA, under the supervision of Jon Einarsen, a licensed geologist with ZGA. The approximate location of the explorations in relation to the pertinent structures and general site boundaries are indicated in Figure 1 (Appendix A).Six direct-push soil explorations (GP-1 to GP-6) were advanced. The direct-push sampling device was supplied and operated by Standard Environmental Probe.

The device utilized a direct-push sampler equipped with disposable PVC sample sleeves. Throughout the drilling operation, soil samples were obtained from four-foot long sample intervals using a lined steel sampler driven into the ground using a percussion hammer. The steel sampling tube was extracted from the hole and the liners were removed and split open. Direct-push explorations GP-1 and GP-2 were

advanced to depths of approximately 22 feet below the ground surface (bgs). Exploration GP-5 and GP-6 were advanced to depths of approximately 20 feet bgs. Explorations GP-3 was advanced to a depth of 24 feet bgs, and GP-4 was advanced to a depth of 23 feet bgs. An effort was made to sample soil continuously from the ground surface to the total depth of each exploration, but sample recovery varied in each exploration.

A field log of each direct-push exploration was maintained, including the thickness and depth of each soil unit encountered and the approximate depth to the uppermost water table. Soil samples were observed to document soil lithology, color, and moisture content. Soils were logged in general accordance with American Society for Testing and Materials (ASTM) Practice Designation D-2488, Standard Practice for Description of Soils (Visual-Manual Procedure). Exploration logs are included in Appendix B of this report.

2.2 Soil SamplingSoil samples retained for chemical analysis and asbestos-containing materials from the direct-push explorations were collected at depths ranging from approximately 4 feet to 24 feet bgs (Table 1). These consisted of 14 fill soil samples and four native soil samples. All soil samples were extracted by hand from the direct-push sample liner using disposable gloves and placed directly into laboratory supplied glassware. Samples designated for the analysis of gasoline were preserved in accordance with EPA Method 5035B.

Each sample container was labeled with the site name, date, time, exploration number, sample number, and sampling personnel. Sample containers were placed in a chilled cooler immediately after sampling, and subsequently transported to the analytical laboratory by ZGA under chain-of-custody procedures.

Investigation-derived waste (IDW, consisting of soil cuttings, temporary monitoring well development water, and equipment cleaning water) generated during the field activities was placed in Department of Transportation (DOT) approved steel drums, closed and appropriately labeled with project-specific information and accumulation date. It is our understanding that the Port of Everett will dispose of the IDW.

2.3 Groundwater SamplingA temporary piezometer was placed into GP-1 and left undisturbed for approximately six hours in an effort to reduce turbidity. The piezometer was subsequently developed with a peristaltic pump until the discharging groundwater was visually clear. Approximately 20 gallons of well development water was placed in a DOT approved steel drum, closed and appropriately labeled with project-specific information and initial accumulation date. A groundwater sample was collected with a peristaltic pump utilizing low flow techniques. The intake of the polyethylene tubing was set approximately one foot below the top of the water table. Discharge from the pump was directed into sample containers supplied by the laboratory.The sample for dissolved metals was field filtered using a 0.45 micron filter.

2.4 Analytical Laboratory TestingEighteen soil samples were submitted for chemical analysis. Soil samples were analyzed by ALS Laboratories of Everett, a Washington State accredited laboratory, as described below:

• Gasoline range hydrocarbons using Northwest Method NWTPH-GX.• Diesel and extended range hydrocarbons using Northwest Method NWTPH-DX using silica gel to

remove the presence of naturally occurring organic constituents.• Metals (arsenic, lead, copper, and antimony) using EPA Method 6020.• Polycyclic aromatic hydrocarbons (PAH) using EPA Method 8270 SIM.

One groundwater sample was analyzed by ALS Laboratories of Everett as described below:

• Gasoline range hydrocarbons using Northwest Method NWTPH-GX.• Diesel and extended range hydrocarbons using Northwest Method NWTPH-DX using silica gel.• Volatile organic compounds using EPA Method 8260.• Semi-volatile organic compounds using EPA Method 8270.• Polycyclic aromatic hydrocarbons (PAH) using EPA Method 8270 SIM.• Polychlorinated biphenyls (PCB) using EPA Method 8082.• Total and dissolved RCRA 8 metals (mercury, arsenic, barium, cadmium, chromium, lead,

selenium, and silver) and copper and antimony using EPA Method 200.8.

Eighteen soil samples were additionally analyzed for the presence of identifiable asbestos fibers using polarized light microscopy (PLM) in accordance with the EPA 600/R-93-116 test method by NVL Labs of Seattle, Washington.

The executed chain-of-custody forms and laboratory analytical certificates are provided in Appendix C. All analyses were completed using standard turnaround times. Data packages were checked for completeness immediately upon receipt from the laboratory to ensure that data and QA/QC information requested were present. Data quality was assessed by considering holding times, surrogate recovery, method blanks, matrix spike and matrix spike duplicate recovery, and detection limits.

3.0 LIMITED SITE ASSESSMENT RESULTS

3.1 Subsurface ConditionsDetailed lithologic descriptions are presented on the soil boring logs included in Appendix B and are additionally described in our Geotechnical Investigation (submitted under separate cover). In general, subsurface conditions consisted of a heterogeneous mixture of fill soils to depths ranging from about 16to 20 feet beneath the ground surface. The fill soils generally consist of gray sand, silty sand and sandy siltwith varying amounts gravel mixed with shell fragments and black, fine wood fragments. Native soil consisting of gray or brown sand with a trace to some gravel was encountered beneath the fill in all six explorations.

Groundwater was encountered in each of the direct-push borings at depths of about 3 to 3½ feet at the time of probing.

3.2 Analytical Laboratory ResultsThe analytical results for soil presented in Table 1 are compared to Method A cleanup levels defined in the Model Toxics Control Act (MTCA, WAC 173-340). Analytes with no Method A cleanup levels arecompared to the most stringent Method B cleanup levels. Complete laboratory reports and chains-of-custody are included in Appendix C. Additional discussion and interpretation of analytical results relative

to applicable cleanup levels are included in Section 4.

Laboratory analytical methods have a lowest detectable concentration of an analyte in a sample that can be reported with confidence. This value is referred to as a practical quantification limit (PQL) and is determined by the sample medium, the method of analysis, the technology available for analysis, interference from high levels of other contaminants, and the laboratory’s confidence in the process.Samples with concentrations of analytes that do not exceed PQLs are referred to as non-detect (ND).

Soil QualityEighteen soil samples were collected and analyzed. These included 14 samples of fill soil and four samples of the underlying native sand. Asbestos was not detected in any of the samples. Total petroleum hydrocarbons were not detected in any of the samples, except as noted below:

• Diesel-range and oil-range TPH were detected at concentrations of 31 mg/kg and 160 mg/kg, respectively, in Sample GP5-1, collected at depth of approximately 4 feet. These concentrations are below the Method A cleanup levels established for diesel and oil (2,000 mg/kg).

Polycyclic aromatic hydrocarbons (PAH) were not detected, except as noted below:

• Naphthalene, 2-Methylnaphthalene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, chrysene, and/or pyrene were reported in very low concentrations in samples in GP5-2, GP6-1, GP6-2, and GP6-3. None of the reported concentrations exceeded the most stringent MTCA Method B cleanup level (groundwater protection).

In particular, it should be noted that carcinogenic PAH (cPAH) were not detected in any of the soil samples, except that chrysene was reported at a concentration of 0.021 mg/kg in one sample. The most stringent cleanup level for chrysene is the Method B cleanup level for groundwater protection under saturated conditions, established at 4.77 mg/kg.

Arsenic and lead were detected in every soil sample, but in concentrations below the MTCA Method A cleanup level. Copper was also detected in every sample, and exceeded the Method B cleanup level for groundwater protection in 7 of 18 samples. The reported concentrations for copper do not exceed the Method B cleanup level for direct contact, established at 3,200 mg/kg. As described below, copper was not detected above the PQL in groundwater. Antimony was not detected above the laboratory PQL in any soil sample.

The PQL for antimony (0.50 mg/kg) in soil exceeds the most stringent MTCA Method B cleanup level for groundwater protection (0.272 mg/kg), but does not exceed the Method B cleanup level for direct contact (32 mg/kg). As described below, antimony was not detected above the PQL in groundwater.

Groundwater QualityOne groundwater sample was collected from GP-1 using low flow techniques. Total petroleum hydrocarbons, semi-volatile organic compounds, volatile organic compounds, and PCBs were not detected above the PQL in the sample.

A single PAH (acenaphthene) was reported at a concentration of 0.053 ug/L, which is below the Method B cleanup level established at 960 ug/L. No other PAH were detected above the PQL.

Total and dissolved mercury, cadmium, chromium, lead, selenium, silver, copper, and antimony were not detected above the laboratory PQL. Total and dissolved barium were reported at concentrations of 16 ug/L and 14 ug/L, respectively, which is below the Method B cleanup level for groundwater (2,000 ug/L). Total and dissolved arsenic were reported at concentrations of 8.6 and 8.0 ug/L, which exceeds the Method A cleanup level for groundwater (5 ug/L).

We also reviewed the Water Quality Standards for Surface Waters of the State of Washington (WAC 173-201A, August 1, 2016). The most stringent fresh water and marine water quality standards for arsenic are 190 ug/L and 36 ug/l, both of which exceed the concentration of arsenic measured in our study. A surface water quality standard for barium is not defined in WAC 173-201A.

3.3 Quality Assurance/Quality Control ResultsThe analytical results for the current investigation were checked for completeness immediately upon receipt from the laboratory to ensure that data and QA/QC information requested were present. Data quality was assessed by considering hold times, surrogate recovery, method blanks, matrix spike and matrix spike duplicate (MS/MSD) recovery, and detection limits. QA/QC review was completed using guidance described in USEPA Contract Laboratory Program National Functional Guidelines for Superfund Organic Methods Data Review (Draft Final, USEPA, 2005). Our evaluation assumes that the QA/QC is correct as reported by the laboratory, and merely provides an interpretation of the QA/QC results.

Hold Times. All analyses were completed within specified hold times.

Surrogate Recoveries. All surrogate recoveries were within laboratory limits.

Method Blanks. Analytes were not detected in any of the laboratory method blanks.

MS/MSD Results. MS and MSD recoveries were all within laboratory limits, and Relative Percent Differences (RPDs) between MS and MSD recoveries were all within laboratory limits.

Laboratory Reporting Limits. Reporting limits were below relevant MTCA cleanup levels, except as noted below:

• The PQL for antimony (0.50 mg/kg) in soil exceeds the most stringent MTCA Method B cleanup level for groundwater protection (0.272 mg/kg), but does not exceed the Method B cleanup level for direct contact (32 mg/kg). Antimony was not detected above the PQL in groundwater.

Based upon our interpretation of quality control information provided by the laboratories, it is our opinion that the overall dataset is useable as qualified for the purposes of this Phase II Environmental Site Assessment.

4.0 FINDINGS AND DISCUSSIONZGA completed a Site Characterization for the Port Gardner Substation for the purpose of characterizing the underlying fill soil and groundwater for off-site disposal and for worker health and safety. Six direct-push explorations were advanced to depths of 20 to 24 feet. In general, subsurface conditions consisted of a heterogeneous mixture of fill soils to depths ranging from about 16 to 20 feet beneath the ground surface. The fill soils generally consist of gray sand, silty sand and sandy silt with varying amounts gravel mixed with shell fragments and black, fine wood fragments. Native soil consisting of gray or brown sand with a trace to some gravel was encountered beneath the fill in all six explorations. Groundwater was encountered in each of the direct-push explorations at depths of about 3 to 3½ feet at the time of probing.

Fourteen fill soil samples and four native soil samples were collected and analyzed for asbestos, TPH, PAH and metals (antimony, arsenic, lead, and copper). Asbestos was not detected in any of the soil samples. Diesel-range and oil-range TPH was detected in only one of 18 soil samples, in concentrations below the Method A cleanup levels. Very low concentrations of certain PAH were reported in 4 of 18 soil samples, but in concentrations below the most stringent Method B cleanup levels. Arsenic and lead were reported in concentrations below the Method A cleanup level in all soil samples. Copper was reported in concentrations exceeding the most stringent Method B cleanup level (groundwater protection) in 7 of 18 soil samples, but the concentration of copper did not exceed the Method B cleanup level for direct contact in any of the soil samples. Antimony was not detected in any of the soil samples.

One groundwater sample was collected and analyzed for TPH, PAH, semi-volatile organic compounds(semi-VOC), volatile organic compounds (VOC), PCBs, the RCRA 8 Metals (mercury, arsenic, barium, cadmium, chromium, lead, selenium, and silver) and copper and antimony. TPH, semi-VOC, VOC, PCBs, mercury, cadmium, chromium, lead, selenium, silver, copper and antimony were not detected above the laboratory PQL. Barium was reported at concentrations below the Method B cleanup level. Arsenic was reported at concentrations slightly above the Method A cleanup level.

A Soil and Groundwater Management Plan (SGMP) has been prepared for the Ameron/Hulbert Site by Landau Associates (2017) as part of the overall cleanup efforts at the Site. The purpose of the Plan is to help guide soil and groundwater management during construction and other intrusive activities at the Site, of which the Property comprises a small part. According to the SGMP:

“The requirements thatapply to intrusiveactivities throughout theSite,excluding thedesignated Soil Management Areas (described below), consist of the following:

• All intrusive activities that have the potential to contact contaminated soil will be performed under a Health and Safety Plan that addresses all applicable state and federal requirements.

• Imported material for use as backfill shall meet Site cleanup levels (CULs), which can be exhibited by a quality report either provided by the source or obtained by the Port.

• Information will be submitted to Ecology from the property owner, or in coordination with the property owner if the work was conducted by a third party, documenting the intrusive activities, presenting all environmental data, summarizing post-intrusive activity environmental conditions, and identifying any changes proposed to the restrictive covenant as a result of the intrusive activities.

Excavated soil shall be handled according to the following requirements:

• Excavated soil that does not contain previously encountered contaminated materials described in Section 4.0 (of the SMGP), or other visual or olfactory indications of potential contamination, may be replaced in the excavation or reused subject to the limitations in the following bullets.

• Excavated material that exhibits any of the conditions of previously encountered contaminated material described in Section 4.0 (of the SMGP), or exhibits other indications of potential contamination (e.g., discoloration, odor), shall be stockpiled separately from unaffected soil and tested to determine appropriate management requirements.

• No excavated soil is to be reused at locations outside of the Site without adequate testing to confirm that the soil does not exceed any MTCA soil CULs.

• Any soil removed from the Site must also meet all other applicable regulations, including the Solid Waste Handling Standards (WAC 173-350).

• Any soil that is tested and exceeds the Site CULs or other applicable criteria must be properlydisposedofatanoffsitepermitteddisposalfacility.”

The SGMP and the RI/FS prepared by Landau (2014, 2017) identify several Soil Management Areas (SMAs) at the Site,includingsome“isolated”SMs. These include an isolated SMA identified as SMA M-1a, which is located on or immediately proximal to the Property. According to the SGMP (page 5-7):

“The location of SMA M-1a is shown on Figure 7. A maximum detected cPAH Toxic Equivalency Quotient concentration of 1.01 mg/kg exceeded the Site CUL along the northern sidewall of an interim action excavation extending to approximately 2 feet bgs conducted south of the Ameron office building. The extent of contamination was bounded in all directions by previous investigations, as shown on Figure 7 and this exceedance appears to be an isolated occurrence.”

These results are generally consistent with our (ZGA) findings, except that cPAH were not detected orwhere detected (chrysene in one sample) was below the Site CULs.

According to the SGMP (page 5-6):

“Soil within the isolated SMAs needs to be properly characterized and managed and, if determined to be contaminated, properly disposed of at an off-site permitted disposal facility. Because soil CUL exceedances were infrequent and/or the concentrations were relatively low, soil characterization may demonstrate that soil within these SMAs do not require management as contaminated soil. Soil characterization can be limited to visual screening for signs of potential contamination if the soil is planned for reuse within the Site. Analytical testing is required if visual screening indicates potential contamination, or if soil is to be reused or disposed of outside of the Site.”

In our opinion, the sampling and analysis described in Section 3 of this Site Characterization report is sufficient to characterize the Property in accordance with the SGMP.

In regard to groundwater, the SGMP states that:

“TherestrictivecovenantfortheSiterequiresthatgroundwaternotbeusedforpotablewater purposes and that any groundwater extracted for construction dewatering or other non-potable purposes be managed, treated, and discharged in conformance with this Plan. Groundwater extracted for purposes other than construction dewatering is not addressed in this Plan and would require review and approval by Ecology.

Groundwater sampling and testing in advance of construction dewatering would be required to determine management requirements. If testing demonstrates that groundwater does not exceed any of the Site CULs, extracted groundwater could be infiltrated on site, if appropriate, or it could be discharged to the City of Everett sanitary or stormwater sewer systems, subject to obtaining a temporary discharge permit from the City. Alternatively, the contractor could select other means of disposing of extracted groundwater, subject to local, state, and federal regulations.

If groundwater is determined to contain concentrations exceeding Site groundwater CULs, as presented in Table 1, it cannot be infiltrated on site. The groundwater would need to be discharged to the City of Everett sanitary sewer, subject to obtaining a temporary discharge permit, or managed by other means that comply with local, state, andfederalregulations.”

5.0 RECOMMENDATIONSIn general, construction at the Property should be completed in accordance with the SGMP. In accordance with the SGMP, soil to be exported from the site should be stockpiled and analyzed for Site COC prior to off-site disposition. According to Landau (2014) COC in soil at the overall North Marina Ameron/Hulbert Site consist of carcinogenic polycyclic aromatic hydrocarbons (cPAH), antimony, arsenic, copper, lead, and total petroleum hydrocarbons (TPH).

The only CUL exceeded in our groundwater sample was for arsenic, detected at a total metals concentration of 8.6 ug/L. The arsenic CUL is 5 ug/L. The City of Everett waste water limit for arsenic is 500 ug/L (Everett Municipal Code 14.40.080). The most stringent fresh water and marine water quality standards for arsenic are 190 ug/L and 36 ug/l (WAC 173-201A). Based on these parameters, it is our opinion that construction dewatering effluent can likely be discharged to the City of Everett sanitary seweror stormwater sewer. A permit may be needed, and the groundwater may need to be treated for turbidity and analyzed for Site COC prior to discharge. According to Landau (2014), COC in groundwater at the overall North Marina Ameron/Hulbert Site consist of copper, arsenic, TPH, 1-1-dichloroethylene, and bis(2-ethylhexyl) phthalate in groundwater.

Based on the results for arsenic in groundwater at the Property, and because other COC that exceed human health direct contact cleanup levels have been identified elsewhere on the North Marina Ameron/Hulbert Site, it is our opinion that the earthwork contractor will need to prepare a site Health and Safety Plan (HASP) to satisfy the requirements as set forth in 29 CFR 1910.120 and Chapter 296-843 WAC intended to ensure safe work practices. This HASP should also apply to all subcontractors during excavation and shoring when working on the Property. The earthwork contractor should make available an appropriate number of employees who satisfy the requirements as set forth in the contractor-specific Health and Safety Plan. In particular, a select number of the contractors’workforceshould be responsible

Dear Mr. Einarsen ,

Enclosed please find test results for the 18 sample(s) submitted to our laboratory for analysis on4/6/2017.

Examination of these samples was conducted for the presence of identifiable asbestos fibers usingpolarized light microscopy (PLM) with dispersion staining in accordance with both EPA 600/M4-82-020,Interim Method for the Determination of Asbestos in Bulk Insulation Samples and EPA 600/R-93/116Method for the Determination of Asbestos in Bulk Building Materials.

For samples containing more than one separable layer of materials, the report will include findings foreach layer (labeled Layer 1 and Layer 2, etc. for each individual layer). The asbestos concentration inthe sample is determined by calibrated visual estimation.

For those samples with asbestos concentrations between 1 and 10 percent based on visual estimation,the EPA recommends a procedure known as point counting (NESHAPS, 40 CFR Part 61). Pointcounting is a statistically more accurate means of quantification for samples with low concentrations ofasbestos.

The detection limit for the calibrated visual estimation is <1%, 400 point counts is 0.25% and 1000 pointcounts is 0.1%

Samples are archived for two weeks following analysis. Samples that are not retrieved by the client arediscarded after two weeks.

Thank you for using our laboratory services. Please do not hesitate to call if there is anything further wecan assist you with.

Sincerely,

Enc.: Sample Results
