1.0 INTRODUCTION

This report presents the results of URS Corporation’s (URS) Limited Phase II Investigation conducted at the B-Box property (subject property) located in Seattle, Washington (Figure 1). The subject property, if acquired, is slated for redevelopment which will include demolition of the existing structures, and construction of a new Nordic Heritage Museum which will also include the adjacent property to the east. The investigation presented herein was performed to assess the soil and groundwater quality in areas of concern identified during URS’ Phase I Environmental Site Assessment (ESA) recently completed at the subject property. Information regarding the site background and the prior investigations are summarized below.

1.1 SITE DESCRIPTION AND TOPOGRAPHY

The subject property is located at 5400 28th Avenue NW in Seattle (Ballard), King County, Washington (Figure 1) and consists of two legal parcels comprising approximately 0.6-acres (Figure 2). The property is developed with two contiguous buildings totaling approximately 21,000 square feet (SF) which occupy the majority of the property. Directly south of the building is a paved area bounded by a fence.

The property is bounded on the north by NW Market Street beyond which is a former gas station; to the east by a contiguous building formerly occupied by Fenpro Industries; to the south by a rail line and to the west by 28th Avenue NW and the former Fentron Building Product Company (Fentron) window manufacturing facility. Land in the site vicinity consists primarily of industrial, light industrial and retail operations.

The site slopes gently to the south and ranges in elevation from approximately 30 to 28 feet above mean sea level (msl). The nearest perennial surface water feature is Salmon Bay located approximately 150 feet south of the subject property (Figure 1).

1.2 PREVIOUS INVESTIGATIONS

URS recently performed a Phase I ESA at the subject property as part of the acquisition due diligence. In addition, previous assessments of the Fenpro (2601 through 2633 NW Market Street) and Fentron (2801 NW Market St.) facilities (Figure 2) were reviewed and have included portions of the subject property. Environmental information pertaining to the subject property is summarized below.

1.2.1. URS 2009 Phase I Environmental Site Assessment

URS’ historical research indicated that the subject property was undeveloped (e.g., tidal flats associated with the Salmon Bay Waterway) prior to the early 1900’s and by the early 1920’s commercial development was noted and filling of the area was apparent. Various businesses (e.g., blacksmith and carpenter shop) occupied the site from 1940 through the 1960’s. In the late 1960’s, the subject property building was a part of the “Fentron Steel Works” associated with steel casting and then aluminum extruding window manufacturing operations. The subject property was referred to as the foundry building and was also listed as a Glass Storage and Aluminum Foundry with the names of “Fenpro” and “Walters and Wolff”. From the 1990’s through the present, the subject property has been leased to various tenants, including a machine shop and diesel engine repair and artist studios. A closed in place underground storage tank (UST) was identified in the northeastern corner of the subject property building (Figure 3).

I:\WM&RD\Robinson Company\Nordic Heritage Museum\NHM Phase I & II\Ph II ESA\B-Box\Report\Phase II Investigation Rpt.doc URS CORPORATION 2

The UST reportedly was a 5,000 gallon capacity tank storing bunker oil; however, it was also indicated to be a 10,000 gallon UST (SE&S, 1997). Four monitoring wells were noted south of this tank (Figure 3).

With regard to surrounding properties with the potential to have affected the subject property, three sites were identified during this assessment. The adjacent Fentron facility had documented impacts to soil and groundwater and is a listed contaminated site. A groundwater volatile organic compound (VOC) contamination plume which includes tetrachloroethene (PCE) and vinyl chloride has been documented to have migrated off site. The contiguous property to the east formerly occupied by Fenpro has been investigated and petroleum impacts to soils have been documented. A service station (former Texaco/Arco) north of the subject property (across NW Market Street) was decommissioned in 2008 and was a confirmed leaking UST site with known impacts to soil and groundwater.

Based on the findings of the Phase I ESA, the former industrial site uses (e.g., foundry and site filling) and the adjacent industrial operations/contaminated sites as well as the upgradient service station were considered recognized environmental conditions (RECs) which warranted further assessment of the subsurface conditions at the subject property.

1.2.2. Rodman 2003 Site Investigation Fenpro Property

This investigation included the entire Fenpro property. Two soil borings completed south of the subject property building (Figure 3) during a prior investigation (Rodman, 2000) were summarized in this report and two of the four monitoring wells located within the eastern half of the subject property building were sampled during this investigation. Ten soil borings were also completed east of the subject property. Historic information regarding the former site uses was not presented in this report and operations at the site were reported to include artist studios, offices, a small precision parts manufacturer, a machine shop, and warehousing businesses. Soil borings completed along the south side of the existing subject property building were field screened to a depth of 12 feet below ground surface (bgs) and reportedly did not identify evidence of petroleum hydrocarbon sheen or odor. The monitoring well samples reportedly did not detect diesel or oil-range petroleum hydrocarbons. Groundwater was noted at 8 to 9 feet bgs.

Prior soil boring data from investigations conducted in 2000 and 1997 at the Fenpro property was briefly summarized and only “low levels of hydrocarbons” were reportedly detected, the highest concentration being 260 milligrams per kilogram (mg/kg). This contamination was reported to be 1 to 2 inches bgs. The report concluded that field screening and analytical data “indicated there is no hydrocarbon or chemical contamination of concern at this site”.

1.2.3. Rodman 2000 Site Investigation Fenpro Property

This limited site investigation was prepared for Fenpro Limited Partnership to assess selected areas of the Fenpro production facility. The report indicated that approximately 30,000 SF of the 100,000 SF property was occupied by an aluminum extrusion business and the remainder of the site was occupied by a small boat manufacturer and office space. The aluminum extrusion business reportedly operated at the site for approximately 40 years. No significant quantities of chemical use nor spill or releases were reported. Six borings (B1 through B6) were completed and the report presented the results of prior soil analytical testing for Geoprobe borings and borings completed in 1997. Boring B3, located south of the aluminum extrusion press area had some field evidence of organic vapors, but the report indicated it was “probably created by non-volatile hydrocarbon materials in the backfill”. Based on the analytical results, it was concluded that no significant areas of contamination exist and the petroleum hydrocarbon contamination identified was below applicable cleanup levels.


1.2.4. SE&S 1997 Phase II Soil Assessment Report (Lot 4 through Lot 10) 2601 NW Market St.

Sound Environment & Safety (SE&S) conducted an assessment of the Fenpro property to evaluate the near surface environmental soil conditions along the south side of the site. This investigation was conducted east of the subject property. It was reported that the Fenpro facility designed and fabricated extruded aluminum products for at least the last 30 years. Historical use of cutting oils and diesel powered equipment were noted. The study included 19 soil boring locations and soil samples were field screened. A slight sheen was noted on some of the soil samples and the soil conditions noted consisted of surficial fill material 2 to 3 feet in thickness which included glass, brick and wood debris as well as a “foundry slag-like material” (e.g., black granular material). The fill was underlain by black to dark brown silty sand to 10 feet bgs. Groundwater was noted at approximately 4.5 to 6 feet bgs. Fifteen of the 26 soil analytical samples detected diesel or oil-range petroleum hydrocarbons exceeding 200 mg/kg, the former Washington Model Toxics Control Act (MTCA) Method A cleanup level. The highest diesel and oil-range petroleum hydrocarbon detections were noted in borings BH-2 (560 mg/kg) and GP-10 (980 mg/kg). Total petroleum hydrocarbons were detected in GP-4 at a concentration of 4,719 mg/kg. The report concluded that the soils did not exhibit typical characteristics of significant petroleum contamination and its presence was likely associated with the fill material used to raise the site grade. A possible source of the fill material was foundry slag generated at the adjoining properties to the west (Fentron facility).

1.2.5. Sweet-Edwards/EMCON 1989 Observation of Fentron Site Cleanup Final Report

This report documents the cleanup activities at the adjacent Fentron facility, which formerly included the western portion of the Fenpro property. A 10,000 gallon bunker oil UST was reported beneath the foundry on the subject property. This UST was reportedly cleaned and closed in place. During the cleanout of floor drains and catch basins some of the exterior catch basins detected elevated levels of metals (e.g., chromium, lead and zinc) and aromatic and chlorinated VOCs. However, the limited sampling of catch basins at the foundry did not detect significant levels of VOCs in water samples.

2.0 OBJECTIVES AND SCOPE

The primary objective of the Limited Phase II Investigation was to evaluate if the historic site operations and/or adjacent contaminated properties have affected the soil and groundwater quality at the subject property. To achieve these objectives, URS implemented the following scope of work:

• Advanced six soil borings (URS-B1 through URS-B6) at selected locations at the subject property using a limited access hydraulic push probe drill rig on July 29, 2009.

• Collection of soil samples from selected borings for chemical analysis for VOCs by EPA Method 8260B; gasoline-range petroleum hydrocarbons using Method NWTPH-Gasoline extended (Gx); diesel to heavy oil-range petroleum hydrocarbons (NWTPH-Dx); semi-VOCs including polycyclic aromatic hydrocarbons (PAHs), polychlorinated byphenols (PCBs) and RCRA-8 metals.

• Collection and analysis of groundwater samples from selected borings and three on-site monitoring wells (MW-T6-1, MW-T6-3, and MT-T6-4) for VOCs, diesel through gasoline-range petroleum hydrocarbons, and total metals (unfiltered).

• Preparation of this report presenting our findings and conclusions.


The following sections provide a description of the field procedures and specific approach utilized in this investigation.

3.0 METHODS OF INVESTIGATION

3.1 SAMPLING LOCATION RATIONALE

A total of six soil borings were drilled: two along the southern exterior of the property (URS-B1 and URS-B2) and four within the building (URS-B3 through URS-B6). The soil boring locations are shown on Figure 3 and the rationale for the boring locations is provided in Table 1.

3.2 DRILLING AND SAMPLING PROCEDURES

Prior to implementing the investigation, the One Call utility notification service was contacted to demark the public utilities to the property boundary. URS contracted Applied Professional Services, Inc. (APS) of North Bend, Washington, to complete a site-specific utility clearance within the property boundary. APS located existing utilities on the property and cleared the soil boring locations. URS also met with representatives of the Robinson Company and the property manager to scope out the proposed boring locations.

The drilling and sampling services were provided by Cascade Drilling of Woodinville, Washington and were completed on July 29, 2009. The borings were advanced using a hydraulic push probe (GeoProbe) limited access drilling rig. Soil samples were collected continuously and were screened using a photoionization detector (PID). The PID readings were recorded on the boring logs provided in Appendix A. Generally, the soil samples with the highest PID readings were selected for analysis. The soil samples were collected directly from acetate liners and placed into laboratory-supplied glassware. The sample glassware was placed into a cooler with ice and submitted to the laboratory under chain of custody protocol. All down-hole soil sampling equipment was decontaminated prior to use by washing with a dilute Alconox detergent solution and triple rinsed with tap water. Investigation derived waste was placed in a clearly labeled 55-gallon drum and left onsite pending laboratory analytical results.

3.3 ANALYTICAL METHODS AND APPLICABLE CLEANUP LEVELS

The soil and groundwater samples were submitted for analysis to Fremont Analytical, a Washington Department of Ecology (Ecology) accredited laboratory, located in Seattle, Washington. The soil and groundwater samples were analyzed for the parameters outlined in Table 1. The laboratory analytical report is provided in Appendix B. Groundwater grab samples were obtained from the borings through a 3/4-inch diameter temporary PVC well screen installed within the boreholes. The groundwater samples were collected from the upper portion of the saturated zone using a peristaltic pump. Monitoring well groundwater sampling was accomplished using low-flow groundwater sampling procedures in general conformance with U.S. Environmental Protection Agency (EPA) guidelines (EPA, 1996). Groundwater field parameters were recorded on groundwater sampling logs provided in Appendix C. The groundwater samples collected for metals analysis were not filtered, thus, the results represent total metal concentrations in the groundwater.

The soil and groundwater analytical data are summarized in Tables 2 and 3, respectively, along with their respective Ecology MTCA Method A and B cleanup levels. Based on the nature of the contamination

Based on the recent and prior investigations performed at the subject property and the adjacent Fenpro property, the site is underlain by fill material consisting of very loose to medium dense silty fine to coarse sand with various quantities of fine gravel, organic material (e.g., wood) and debris (e.g., glass, metal wire, slag, and brick fragments). The fill material varied in thickness from approximately 8 to 11 feet and the greatest thickness of filling appears to be in the southern portion of the subject property. Historical information indicated that this portion of the site was adjacent to the pre-development shoreline. Native soils underlying the fill material consisted of alluvium comprised of dark brown to gray silty fine sands and fine to medium sands with trace fine gravel. This material was encountered to the maximum depth explored during this investigation (20 feet bgs). Geotechnical borings completed adjacent to the east of the subject property noted alluvium to a depth of approximately 22 feet bgs (AES, 2008). The alluvium was underlain by glacial outwash deposits (Vashon Advance Outwash

Groundwater was encountered during drilling at depths ranging from approximately 8 feet (URS-B2) to 16.5 feet (URS-B5) bgs at the subject property. Static groundwater levels in the four monitoring wells situated beneath the northeastern corner of the building ranged from approximately 11.9 feet to 12.1 feet bgs. Static groundwater was measured at a depth of 6 feet bgs in the geotechnical piezometer (completed to 30 feet bgs) located near the southeastern corner of the subject property (AES, 2008). No site specific groundwater gradient information was available; however, based upon the topography and investigations conducted at th

The soil field screening results are provided on the boring logs in Appendix A. During field screening of soils, PID readings as high as 1,000 parts per million (ppmv) were noted in borings URS-B1 and URS-B2. Significant staining and odors were not apparent, although, a number of borings had slight odors in the soil samples collected near the groundwater table. As mentioned above, the fill material was noted to contain debris which included a gray to black slag-like material. The exact source of this slag material is not known, but it is plausible that this material m

Selected soil samples from the borings were submitted for analysis and the results are summarized in Table 2. Based on field screening results, the majority of the samples were collected within the site fill material. Gasoline and diesel-range petroleum hydrocarbons were not detected in the soil samples and only one boring (URS-B2) detected oil-range petroleum at a concentration (67 mg/kg) well below the MTCA Method A cleanup level of 2,000 mg/kg. PAHs were detected in a number of the soils samples and the highest concentrations were noted in borings URS-B5 and URS-B6. The total toxicity

• arsenic – 0.011 to 0.059 milligrams per liter (mg/L)

• barium –3.6 mg/L

PCBs were not detected in any of the soil samples. Low levels of VOCs were noted in the soil samples collected from borings URS-B2 and URS-B3. Benzene was the only VOC detected above the MTCA Method A cleanup level of 30 µg/kg. Benzene and toluene were detected at concentrations of 60 µg/kg and 40 µg/kg, respectively, in boring URS-B2 at a depth of 10 feet bgs. This sample was collected within the saturated zone. A shallower sample collected from this boring at 5 feet bgs did not detect benzene or toluene. Low concentrations of two chlorinated VOCs (1,1,1-trichloroethane [TCA] and 1,1-dichloroethane [DCA]) w

The groundwater analytical results are summarized in Table 3. Gasoline, diesel and oil-range petroleum hydrocarbons were not detected in any of the groundwater samples. VOCs were detected in the groundwater including: TCA, DCA, chloroethane, benzene, toluene and methyl tert-butyl ether (MTBE). TCA was detected in monitoring well samples MW-T6-1 (2.3 micrograms per liter [µg/L]) and MW-T6-4 (3.7 µg/L) at concentrations well below the MTCA Method A cleanup level of 200 µg/L. The common biodegradation products of TCA (DCA and chloroethane) were also detected in the monitoring well samples and none of these VOCs exceeded applicable cleanup levels. Very low concentrations of benzene (0.02 µg/L) were detected in boring URS-B5. MTBE, a common gasoline additive, was detected in all of the groundwater samples and ranged in concentration from 0.92 µg/L (URS-B6) to 140 µg/L (URS-B-5). Three of the boring groundwater sampling locations (U

4.3 CONCLUSIONS

Based on the findings of the limited subsurface investigation conducted at the B-Box Property located in Seattle, Washington, URS has drawn the following conclusions:

Soils

• Fill material was noted beneath the entire property and ranged in thickness from 8 to 11 feet. The fill material was very variable and contained debris including glass, wood and metal fragments as well as a slag-like material. The slag material may be associated with the former adjacent Fentron facility steel and aluminum foundry operations. Saturated soils were encountered during drilling at depths ranging from approximately 8 to 16.5 feet bgs. All of the soil samples chosen for chemical testing were collected within the site fill material and were within the unsaturated zone/above the groundwater table with the exception of the 10 foot sample from URS-B2.

• Soil sampling completed beneath the building did not identify petroleum affected soils with the exception of low concentrations at boring URS-B2 at a depth of 10 feet bgs. The shallower sample (5 feet bgs) from this location did not detect petroleum hydrocarbons. Benzene was detected (60 µg/kg) in the deeper sample from this boring at a concentration exceeding the MTCA Method A cleanup level. Toluene was also detected in this sample and the presence of these two compounds is generally associated with gasoline. Considering that this sample was collected in the saturated zone soils may indicate that groundwater impacts exist upgradient from this boring location (Figure 3).

• Low concentrations of the chlorinated solvent TCA and its common degradation products (DCA and chloroethane) were detected in the soil at boring URS-B3 located in the northeastern portion of the subject property building. This solvent is a commonly used degreaser and has been used in numerous products (e.g., cutting oils, lubricants, and woodstains/finishes).

• PAHs were detected in all of the soil samples, however, only two samples detected cPAHs exceeding the applicable cleanup level (URS-B5 and URS-B6). Due to the variable nature of the fill material, the detection of PAHs in the soils is not uncommon in the presence of wood debris (e.g., treated wood fragments) and where petroleum hydrocarbon use has been documented. PCBs were not detected in any of the soil samples.

• With the exception of cadmium, elevated metal concentrations were not evident in the soil samples. Arsenic, barium, chromium, lead, mercury and silver were detected in the soils. The presence of the slag material does not appear to have had a significant impact on soil metal concentrations based on the limited sampling conducted during this investigation.

• Although no specific sources of contamination were identified, it appears that the site fill material may be the source of the general low level contamination noted in the fill, with the exception of the chlorinated VOCs identified in the northeast corner of the subject property. Based on these findings and the presence of slag material in the fill, soils exhumed during the proposed property redevelopment will likely require disposal at a licensed landfill (e.g., Rabanco, Roosevelt Regional Landfill) or equivalent soil remediation facility (e.g., Cemex Everett, WA facility).

• Low concentrations of TCA and its degradation products (DCA and chloroethane) were detected in the groundwater in the northeastern portion of the subject property. These chlorinated VOCs were also identified in the soil sample (URS-B3) collected from this area.

• The common gasoline additive MTBE was detected in the groundwater across the entire property. MTBE concentrations exceeding the applicable cleanup level were noted in three (URS-B1, B4 and B5) of the eight groundwater samples. The highest concentrations were detected in the central portion of the property at boring URS-B5. Sources of gasoline contamination were not identified in the soils in this portion of the property or at upgradient boring locations. The former service station located on the north side of NW Market Street, which lies upgradient of the subject property, is a confirmed leaking UST site with impacts to soil and groundwater. Based on this information, it would appear that the service station property may be the source of MTBE in groundwater. Evidence of gasoline constituents in the soil (e.g., benzene an

5.0 RECOMMENDATIONS

URS advises that a file review be conducted at the Northwest Regional Office of Ecology to obtain available information regarding the upgradient service station to assess if groundwater quality in the area has been affected. We also advise that a contingency plan be developed to address soil removal and management during site redevelopment (e.g., foundation earthwork and soldier pile drilling). In addition, the contingency plan will provide the procedures to be employed in the event that new areas of contamination are identified or USTs are discovered during the construction earth work. URS understands that the proposed building may require excavation into the groundwater table. Thus, dewatering may be required and the safe management and treatment of construction dewatering would also be addressed in this plan.

August 2009 (https://fortress.wa.gov/ecy/clarc/reporting/CLARCReporting.aspx).a In soil, the cleanup level is 100 mg/kg if benzene is not present, and the total of ethylbenzene, toluene, and xylenes is less than 1% of the gasoline mixture. The

cleanup level for all other gasoline mixtures is 30 mg/kg.b Carcinogenic PAH (cPAH) cleanup levels under MTCA are based on the calculated total toxicity of the mixture using the Toxicity Equivalency Methodology in

WAC 173-340-708 (8). The mixture of cPAHs shall be considered a single hazardous substance and compared to the applicable MTCA Method B cleanup level for benzo(a)pyrene.

c TTEC - Total Toxicity Equivalent Concentration(B) - MTCA Method B cleanup level. MTCA Method A cleanup levels for these analytes have not been established.bgs - below ground surface(I) - MTCA cleanup level for industrial property. This level is provided for completeness and does not imply that the industrial screening level is the most

appropriate level to use for data comparison.

th, 2009

Dave: Enclosed are the analytical results for the Nordic Heritage Museum – B-Box soil & water samples submitted to Fremont Analytical on July 29

th 2009.

The samples were received in good condition – in the proper containers, properly sealed, labeled and within holding time. The soil samples were contained in 12 – 4oz soil jars with 24 – 40mL VOAs preserved with MeOH (Trip Blanks were included). The water samples were contained in 9 – 1L Ambers preserved with HCl, 24 – 40mL VOAs preserved with HCl (Trip Blanks were included) & 8 – 500mL HDPE bottles. The samples were received in a cooler wet ice, with a cooler temperature of 5.3°C, which is within the laboratory recommended cooler temperature range (<4°C - 10°C). The samples were analyzed and then stored in a refrigeration unit at the USEPA-recommended temperature of 4°C ± 2°C. There were no sample receipt issues to report. Examination of these samples was conducted for the presence of the following:

Volatile Organic Compounds in Soil & Water by EPA Method 8260B

Gasoline in Soil & Water by NWTPH-Gx

Diesel and Heavy Oil in Soil & Water by NWTPH-Dx/Dx Ext.

Semi-Volatile Organic Compounds in Soil by EPA Method 8270C

PCB's (Polychlorinated Biphenyls) in Soil by EPA 8082

Total Metals (RCRA-8) in Soil & Water by EPA Method 6020

pH by SM4500 H+B These applications were performed under Washington State Department of Ecology accreditation parameters. All appropriate Quality Assurance / Quality Control method parameters have been applied.

Laboratory Notation (EPA Method 8260B – Water, Sample ID: URS-B2-GW): The surrogate recovery for Toluene-d8 exceeded laboratory control limits. The other two surrogates were within range.

Laboratory Notation (EPA Method 6020 – Water, Sample ID: URS-B1-GW): The relative percent difference (RPD) between the sample and the sample duplicate exceeded laboratory control limits for Cadmium (Cd). The RPD values for the Matrix Spike (MS)/MS Duplicate for the same sample/analyte were within range.

Please contact the laboratory if you should have any questions about the results. Thank you for using Fremont Analytical! Sincerely,
