Property Information

Property Description

The Site is located at the northeast corner of the intersection of 15th Street and B Street in Washougal, Washington. The Site currently operates as an ARCO retail gasoline station and convenience store. Current facilities include four (4) 10,000-gallon, double-walled fiberglass gasoline underground storage tanks (USTs) and associated product piping on the north side of the Site, a canopy covering four dual dispenser pumps on the west side of the Site, and a second canopy covering two dual dispenser pumps on the southeast side of the Site. The entire Site is paved with asphalt or concrete with the exception of the station building, fuel dispensers, signage and landscaped areas.

Previous facilities included two 6,000-gallon and two 4,000-gallon single-walled steel gasoline USTs which were decommissioned by removal in January and February 1990 (Sweet Edwards/EMCON 1991). Current and former site configurations are presented in Figure 2. A legal description of the property is presented in Appendix B.

Property Zoning and Location

The property is located in a mixed commercial/residential area of Washougal, Washington. According to the most recent (2008) zoning map produced by the City of Washougal Community Development Department, the Site is located within an area zoned as Town Center Core (TCC), which provides for commercial and residential use.

The Site is bounded to the north by C Street and vacant property and to the east by residential properties. The Site is bounded to the south by B Street and a residential property across B Street and to the west by 15th Street and residential properties beyond 15th Street. The nearest surface water body, the Columbia River, is located approximately 0.17 mile south of the Site. The Washougal River is located approximately 0.45 mile northeast and 0.5 mile north of the Site.

Site Discovery and Definition

During UST decommissioning activities in January and February 1990, a small hole was reportedly observed in one of the gasoline USTs and petroleum-impacted soil was observed in the tank cavity (Sweet Edwards/EMCON 1991). Approximately 60 cubic yards of soil was excavated and placed in an on-site treatment gallery. Figure 2 shows

ARCO Facility No. 6008

the treatment gallery location. The Site was listed on the Ecology Leaking Underground Storage Tank (LUST) database in January 1990.

Property Ownership and Use

Past Ownership and Use

The property was previously owned by ARCO and was sold to the current owner in 2007 (Delta 2007). The property operated as a gasoline service station and convenience store. The following table summarizes former and current UST information:

Tank Installation Decommissioning Tank ID Content Volume Date Date 1 4,000 Gasoline Unknown 1990 2 4,000 Gasoline Unknown 1990 3 6,000 Gasoline Unknown 1990 4 6,000 Gasoline Unknown 1990 5 10,000 Gasoline 1990 Operational 6 10,000 Gasoline 1990 Operational 7 10,000 Gasoline 1990 Operational 8 10,000 Gasoline 1990 Operational

Current Ownership and Use

In 2007, ARCO sold the property to the current property owner, KTK Kanso, LLC. The property continues to operate as a retail gasoline station and currently utilizes four 10,000-gallon USTs located on the west-central portion of the property.

Future Ownership and Use

Future use of the property is anticipated to remain as a retail gasoline station. Additionally, the property is expected to be continued to be zoned for mixed residential and commercial use.

Area Drinking Water Sources

The public water supply for the City of Washougal is obtained from two sources. The primary production facility, located at 411 Third Street, began operations in 1942 with the installation of a public supply well. Four additional wells were installed to meet increased demands in 1947, 1954, 1983 and 2007 (City of Washougal 2009). Ecology well logs were located for the supply wells installed in 1954 and 2007. The 1954 well was drilled to a depth of 103 feet below ground surface (bgs), with a perforated casing between 84.5 and 98 feet bgs. The 2007 well was drilled to a depth of 100 feet and screened between 72 and 92 feet bgs. According to the well logs, clay or topsoil was encountered from the surface to approximately 3 feet bgs. Cobbles and boulders were generally encountered between 3 feet bgs and approximately 60 feet bgs. Gravels and sand with some cobbles were generally encountered between 60 feet bgs and 97 to 99 feet bgs. A layer of clay or gravel with clay was encountered at the terminus of each boring.

A secondary supply source is located at 2801 I Street, with one active well installed in 1931. The secondary source is primarily used in the summer months. City water is treated with chlorine as a precaution against bacteria and sodium hydroxide as a corrosion inhibitor prior to holding in reservoirs (City of Washougal 2009).

According to an EDR Geocheck Report (Inquiry #3057259.1s presented in Appendix C), there are 12 water wells and 1 public supply well located within 1 mile of the property. The nearest water wells were located ½ mile northeast and southeast of the property. The public supply well was located between ¼ and ½ mile northeast of the property. No water wells were found within ¼ mile of the Site. Based on the preceding information, groundwater beneath the Site is not used as a drinking water source and is not expected to be used as a potable water source in the future.

Area Sensitive and Environmental Receptors

According to an EDR Offsite Receptor Report (Inquiry #3057259.2s), there are no environmental receptors within 1 mile of the property. Five sensitive receptors are located within 1 mile of the property, including three daycare facilities (located 1/8 to ¼ mile, ¼ to ½ mile and ½ to 1 mile from the Site, respectively) and two health care facilities (located ½ to 1 mile from the property).

The EDR report did not indicate any environmental receptors within 1 mile of the property, or sensitive receptors within 1/8 mile of the property. Therefore, it is unlikely

Environmental Conditions

Physiographic Setting and Topography

The Site is situated in the Willamette-Puget Trough, which is bordered by the Cascade Range to the east and the Pacific Coast Range to the west (Mundorff 1960). The Site elevation is approximately 45 feet above mean sea level, and the topography of the immediate area is generally flat.

Geology and Hydrogeology

The Site is located in a geographic area known as the Fourth Plains, where Pleistocene-age alluvial deposits dominate the geology. The alluvial deposits form a layer ranging from a few feet to 200 feet in thickness. In regions where the alluvial beds are the thickest, groundwater drains out readily and the water table is deeper than in areas with thinner alluvial beds. The principal geologic formation in the region is the Troutdale formation, which consists primarily of sand and gravel in the upper member and silt and clay in the lower member (Mundorff 1960). The surface geology in the vicinity of the Site is predominantly glacial outwash from Montana and eastern Washington, according to the Washougal Public Works Department. These are generally referred to as “cataclysmic flood deposits” resulting from the collapse of ice dams at Lake Missoula during the Pleistocene epoch.

During the site investigation activities conducted in January 2011, three soil borings (SB-1 through SB-3) were advanced to a maximum depth of 40 feet bgs. Perched groundwater was encountered between approximately 32 and 35 feet bgs in boring SB-3. Groundwater was not encountered during previous site assessments. Lithology observed during drilling activities consisted of gravel and cobbles with sand and silt. A cross section location map and cross section illustrating lithology observed during subsurface investigation are presented in Figures 3 and 4, respectively. Boring logs are provided in Appendix D.

Surface Waters

Annual average rainfall is approximately 45 inches in the Site vicinity (WRCC 2011). Surface water at the Site is limited to runoff from precipitation. The Site is paved with the exception of relatively small landscaped areas, therefore it is likely that infiltration of surface water into the groundwater table is limited. Surface water, floodplains, wetlands and area of sediment deposition are not present at or adjacent to the Site. Therefore,

6

Closure Request

ARCO Facility No. 6008

no known impacts to surface waters have occurred due to the past operation of the Site as a retail gasoline station.

Sediment

Surface waterways and associated sediments are not present at the Site. Therefore, no known impacts to sediments have occurred due to retail gasoline station operations at the Site.

Soil Vapor

Soil vapor investigations have not been conducted at the Site. However, given the current concentrations of constituents of concern (COCs) in soil and groundwater, and current and future use of the Site, petroleum hydrocarbon impacts to soil vapor are unlikely.

Ecological and Natural Resources

The Site is located at a busy intersection in a mixed commercial and residential area of Washougal, Washington. The entire Site is paved with asphalt or concrete with the exception of the station building, fuel dispensers, signage, and landscaped areas. Because there are no contiguous undeveloped lands in the vicinity of the Site, this area is not considered to be suitable habitat to support native vegetation and/or wildlife. Additionally, traffic corridors and similar features surrounding the Site further reduce the potential use of the area by wildlife.

Cultural and Archaeological Resources

There is no indication that cultural and/or archaeological resources are present at the Site. Therefore, no known impacts to cultural and archaeological resources have occurred due to retail gasoline station operations at the Site.

Summary of Previous Site Investigations

In July 1989, four soil borings (B-1 through B-4) were installed by Brown and Caldwell on behalf of ARCO as part of a preliminary tank replacement assessment. The approximate locations of historic soil borings are presented in Figure 2. The borings were installed adjacent to the previous USTs. Refusal was encountered at approximately 3 to 4 feet bgs in each of the borings. One soil sample (B-4 at a depth of 4 feet bgs) was analyzed for total petroleum hydrocarbons by U.S. Environmental Protection Agency Method 418.1. No total petroleum hydrocarbons were detected in the sample. A photoionization detector (PID) was used to screen soil during boring installation. PID readings ranged from 18 to 190 parts per million (ppm) (Brown and Caldwell 1989).

In January and February 1990, ARCO contracted Blakeley Construction, under the oversight of Sweet-Edwards/EMCON, to decommission two 4,000-gallon single-walled steel construction gasoline USTs and two 6,000-gallon single-walled steel construction gasoline USTs and associated product pipelines. The former USTs were replaced with four 10,000-gallon double-walled fiberglass gasoline USTs. During decommissioning activities, a small hole was observed in one of the 4,000-gallon single-walled gasoline USTs and petroleum-impacted soil was encountered in the tank cavity. Petroleum odors were also observed during the excavation of product lines connected to the westernmost dispenser pump (Sweet Edwards/EMCON 1991).

Impacted soils were excavated and stored on site pending the construction of a soil treatment gallery, which would be located in the tank excavation. The existing UST cavity, the new UST cavity and the planned treatment gallery were overexcavated beyond the original width of the UST cavity and deepened to 16 feet bgs. Groundwater was not encountered during site excavation activities (Sweet Edwards/EMCON 1991).

A total of nineteen soil samples were collected from the floor and sidewalls of the UST excavation, dispenser line trenches, and from impacted soils staged on site prior to placement in the treatment gallery. Soil samples were analyzed for benzene, toluene, ethylbenzene and total xylenes (BTEX), total petroleum hydrocarbons-gasoline range organics (TPH-GRO), and total petroleum hydrocarbons-diesel range organics (TPH- DRO). Soil samples collected from the excavation floor and sidewalls did not contain concentrations of petroleum constituents in excess of Washington State Department of Ecology (Ecology) Model Toxics Control Act (MTCA) Method A Soil Cleanup Levels (CULs). One soil sample collected from the piping trench (PR-1 at a depth of 5.5 feet bgs) slightly exceeded the MTCA Method A CUL for TPH-GRO at a concentration of

8

ARCO Facility No. 6008

35 milligrams per kilogram (mg/kg). Excavated soil that was later placed in the treatment gallery contained concentrations of TPH-GRO and total xylenes above MTCA Method A CULs. No benzene or TPH-DRO were observed in any of the soil samples collected at the Site. The Site was listed in the Ecology LUST database in January 1990 during UST decommissioning activities (Sweet Edwards/EMCON 1991).

Approximately 60 cubic yards of soil were excavated from the tank cavity and placed in the on-site treatment gallery located immediately north of the UST complex. The treatment gallery was constructed of five vertical, perforated polyvinyl chloride (PVC) pipes (VP-1 through VP-5) and two 20-foot long, 4-inch diameter, perforated PVC collector pipes installed horizontally at 9 feet bgs. A steel plate was installed between the treatment gallery and the new UST cavity to prevent migration of petroleum constituents. The treatment gallery was capped with layered geotextile and visqueen and was repaved with asphalt. At this time, Ecology had not approved the installation of a vapor extraction system (VES); thus, no system was connected to the treatment gallery (Sweet Edwards/EMCON 1991). Following Ecology approval, a VES consisting of one Rotron DR 505 blower and two Westates VSC-200 carbon canisters was installed and started by EMCON on January 6, 1993. The VES operated until August 25, 1993 when the system was shut down pending confirmation sampling (EMCON 1994).

Confirmation sampling was conducted by EMCON in 1994 with the installation of six soil borings in the treatment gallery. Shallow refusal was encountered in two of the borings. Shallow (4 feet), intermediate (10 feet) and deep (14 feet) soil samples were collected from the four completed borings. Soil samples were submitted for analysis of TPH-GRO, BTEX and total lead. None of the analyzed constituent concentrations exceeded MTCA Method A soil CULs (EMCON 1994). The Site LUST case status was updated to “Reported Cleaned Up” in June 1995; however, a formal declaration of No Further Action was not issued by Ecology (Delta 2007).

In 1998, two soil samples were collected by Pinnacle Environmental Solutions (formerly Sweet Edwards/EMCON) during the installation of a pay-at-the-pump machine located south of the westernmost dispenser pump island. Sample 1 was collected at a depth of 4 to 6 inches bgs. Sample 2 was collected “just off a concrete footing for the canopy”. The specific depth of Sample 2 was not indicated; however, Figure 2 and Photograph 3 of Pinnacle’s June 5, 1998 letter report indicate that it was also collected immediately beneath the concrete surface. Total xylenes and TPH-GRO soil concentrations exceeded applicable MTCA Method A CULs in Sample 1 (Pinnacle, 1998).

ARCO Facility No. 6008

Facility upgrade activities, including the replacement of the six dispenser pumps, were conducted by the current property owner in February 2007. Soil samples were collected at depths ranging from 3 to 6 feet bgs beneath the pump islands. Soil samples were analyzed for BTEX, methyl tertiary-butyl ether (MTBE), TPH-GRO and total lead. Benzene concentrations exceeded current MTCA Method A soil CULs in two of the soil samples (D-3-3.5 and D-4-3.5), which were collected from the westernmost pump island (Delta 2007). Historic soil boring and soil sample locations are presented in Figure 2.

In January 2011, three soil borings (SB-1 through SB-3) were installed to further characterize previous impacts historically encountered at the westernmost dispenser island. Boreholes SB-1 and SB-2 were advanced to depths of 10 and 19.5 feet bgs, respectively, where refusal was encountered. Boring SB-3 was installed to a total depth of 40 feet bgs.

A minimum of two soil samples from each boring were analyzed for BTEX, MTBE, TPH-GRO and total lead at the following depth intervals:

SB-1: 3 to 5 feet bgs and 8 to 10 feet bgs

SB-2: 3 to 5 feet bgs, 8 to 10 feet bgs and 19 to 19.5 feet bgs

SB-3: 3 to 4 feet bgs, 8 to 9 feet bgs, 30 to 30.5 feet bgs, and 39 to 40 feet bgs

Perched groundwater was observed between 32 and 35 feet bgs in boring SB-3. Soil above and below the perched water interval was observed as dry to slightly moist.

None of the analyzed constituents (BTEX, MTBE and TPH-GRO) except for total lead were detected above the laboratory reporting limits in the soil samples. Total lead was detected at concentrations below the MTCA Method A soil CUL.

A grab groundwater sample was collected from boring SB-3 (located on the south side of the westernmost dispenser island) by placing a temporary well screen in the borehole. Prior to sampling, groundwater was purged at a low flow rate with a peristaltic pump for approximately 40 minutes. Less than one gallon of purge water was generated during this time and flow was sporadic. Groundwater flow during purging cleared slightly but a significant volume of colloidal sediment remained after 40 minutes of purging.

ARCO Facility No. 6008

Grab groundwater was analyzed for BTEX, MTBE, TPH-GRO, TPH-DRO, TPH as heavy oil (HO) and total and dissolved lead. BTEX, MTBE, TPH-GRO and dissolved lead were not detected above the laboratory reporting limits. TPH-DRO, TPH-HO and total lead were detected, with concentrations of TPH-HO (550 micrograms per liter [µg/L]) and total lead (108 µg/L) exceeding associated MTCA Method A groundwater CULs (500 µg/L and 15 µg/L, respectively). TPH-DRO and TPH-HO detections are most likely not associated with petroleum but the result of common interferences caused by naturally occurring organic material and organic acids sorbed to the soil that was present in this very turbid sample. This conclusion is further supported by the fact that petroleum hydrocarbons outside of the gasoline range have not been identified in any other samples collected at the Site. The turbid nature of the sample also supports the conclusion that the lead was present with the soil and not dissolved in the groundwater. Dissolved lead was not detected above laboratory reporting limits (10 µg/L) for the grab groundwater sample. A summary of recent soil analytical results is provided in Table 1 and Figure 5. Grab groundwater analytical results are summarized in Table 2 and Figure 6. Historical soil analytical results are summarized in Table 3.

Summary of Previous Remedial Actions

Approximately 60 cubic yards of soil were excavated from during UST decommissioning activities in 1990 and placed in an on-site treatment gallery located immediately north of the former UST complex. A VES was installed and began operation in January 1993. The VES operated until August 25, 1993, when the system was shut down for confirmation sampling (EMCON 1994).

Potential Constituents of Concern

According to MTCA 173-340-900, Table 830-1 “Required Testing for Petroleum Releases,” several potential COCs are associated with the current and past use of the Site. Potential COCs associated with the past storage and distribution of gasoline at the property include:

o BTEX o 1,2-dibromoethane (EDB) o 1,2-dichloroethane (EDC) o MTBE o Total lead o Naphthalene

During historic site characterization activities, the following COCs were identified in soil at concentrations exceeding MTCA Method A soil CULs: benzene, total xylenes and TPH-GRO.

COC MTCA A Sample(s) and Date Location(s) CUL Concentration(s) Benzene 0.03 D-3-3.5: 0.429 2007; Westernmost pump mg/kg mg/kg; 2007 island; D-4-3.5: 0.102 mg/kg Westernmost pump island Total 9 mg/kg Sample 1: 25.8 1998 Westernmost pump Xylenes mg/kg island TPH- 30 mg/kg PR-1: 35 mg/kg; 1990; Piping on southern GRO Sample 1: 513 1998 portion; mg/kg Westernmost pump island

Toluene, ethylbenzene, MTBE, and total lead were not detected above laboratory reporting limits in the samples analyzed for these constituents. EDB, EDC and naphthalene were not analyzed in historic soil samples.

During the 2011 Site Investigation surrounding the westernmost dispenser island, total lead was the only COC detected above the laboratory reporting limit in soil samples. However, the total lead concentrations did not exceed the MTCA Method A soil CUL.

13

Closure Request

ARCO Facility No. 6008

BTEX, MTBE and TPH-GRO were not detected above laboratory reporting limits in the soil samples.

Groundwater was not analyzed during historic site investigation activities. During the 2011 Site Investigation, a grab groundwater sample was collected from what is believed to be a perched water-bearing zone from the south side of the westernmost dispenser island in boring SB-3. BTEX, MTBE, TPH-GRO and dissolved lead were not detected above laboratory reporting limits in the grab groundwater sample. TPH-DRO, TPH-HO and total lead were detected, with concentrations of TPH-HO and total lead exceeding the associated MTCA Method A groundwater CULs.

In summary, COC concentrations exceeding MTCA Method A CULs in soil include benzene, total xylenes and TPH-GRO. None of the potential COCs for a gasoline service station exceeded the MTCA Method A groundwater CULs with the exception of total lead (dissolved lead was not detected in the grab groundwater sample). TPH- DRO and TPH-HO were detected in the grab groundwater sample, with TPH-HO exceeding the applicable MTCA Method A groundwater CUL. TPH-DRO and TPH-HO are most likely not associated with petroleum but the result of common interferences caused by naturally occurring organic material and organic acids sorbed to the soil that was present in this very turbid grab groundwater sample.

Conceptual Site Model

Possible pathways associated with potential exposures to concentrations of petroleum hydrocarbon constituents detected in soil and groundwater at the Site are described below. The conceptual site model (CSM), or exposure evaluation flowchart, illustrated on Figure 7 provides a summary of the relationships between primary sources (i.e. release mechanisms), secondary sources (i.e. exposure media), transport mechanisms, exposure pathways, and potential current and future receptors. Details of the CSM for the Site are provided in the following sections.

Potential Constituent Sources

COCs in soil include benzene, total xylenes and TPH-GRO, as these constituents were historically present above MTCA Method A soil CULs in shallow soil samples collected at the Site. However, recent soil investigation activities show that historic COCs are currently below laboratory reporting limits. COCs in groundwater include TPH-DRO, TPH-HO and total lead, as these constituents were present at concentrations exceeding MTCA Method A groundwater CULs in a grab groundwater sample collected at the Site.

The primary source of residual soil COCs at the Site includes the historic release of gasoline to soil. A hole was observed in one of the former gasoline USTs during UST decommissioning activities in 1990. Impacted soil was excavated and treated onsite. Detections of TPH-GRO and/or benzene exceeding MTCA Method A soil CULs have also been reported in samples collected near the surface at the westernmost dispenser island. The TPH-GRO concentration in a 1990 piping trench sample (PR-1 at 5.5 feet bgs; 35 mg/kg) did not exceed cleanup guidelines at the time it was sampled (Sweet Edwards/EMCON 1991). However, the concentration would marginally exceed the current MTCA Method A soil CUL of 30 mg/kg.

The primary source of groundwater COCs at the Site is not known. No known diesel and/or heavy oil range hydrocarbon release has occurred at the Site. The current and previous property owner operated the Site as a gasoline-only service station.

The primary source of COCs at the Site is considered to be potential spills, overfills and leaks from the former UST basin. The secondary source is considered to be direct release of gasoline to surface soil (<15 feet bgs). Subsurface soils (>15 feet bgs) have not been found to contain hydrocarbon impacts; therefore, subsurface soils are not considered for this CSM.

ARCO Facility No. 6008

Potential Transport Mechanisms and Receptors

The Site is currently paved with asphalt and concrete and is expected to remain the same in the future as there are no plans for redevelopment of the Site. The pavement serves as a barrier between potential receptors and surface (<15 feet bgs) soil. Although hydrocarbon-impacted soil had historically been identified at the former UST basin, impacted soil was excavated down to 16 feet bgs and confirmation soil samples collected from the bottom and sidewalls of the UST basin indicated that hydrocarbon- impacted soil is no longer present in this area. Hydrocarbon-impacted soil had also been identified in surface soil at the westernmost dispenser island in 1998 and 2007. However, samples collected in January 2011 to further characterize soil in the vicinity of the westernmost dispenser island did not show petroleum hydrocarbon impacts.

A direct contact transport mechanism is unlikely. Therefore, potential incidental ingestion of and dermal contact with soil for current and future on-site commercial workers and future on-site construction/utility workers are unlikely; these exposure pathways are not expected to be complete. In addition, inhalation of fugitive dust by potential onsite and offsite receptors, including commercial workers and offsite residents, is unlikely and the exposure pathways are incomplete.

Leaching of residual phase petroleum hydrocarbons in soil to groundwater beneath the Site may lead to exposures through tap water ingestion, dermal contact with tap water and inhalation of volatile organic compounds (VOCs) in tap water to potential on-site and off-site receptors. However, groundwater beneath the Site is not used as a drinking water source and is not expected to be used as a potable water source in the future. Thus, these exposure pathways are unlikely to be complete.

Another potential transport mechanism at the Site may include volatilization of constituents in soil and/or groundwater to outdoor air and/or indoor air of current and future on-stie buildings, or air within a trench used by future onsite construction/utility workers. These exposure pathways are unlikely because historically impacted soil in the UST basin was overexcavated to 16 feet bgs and no soil impacts were identified in confirmation soil samples. Additionally, individual VOCs were either not detected above laboratory reporting limits in the grab groundwater sample collected in January 2011 or were detected at concentrations below MTCA-A groundwater CULs. Moreover, historic petroleum hydrocarbon-impacted soil has not been located beneath the current station building, redevelopment of the Site is not planned for the future, and possible residual petroleum hydrocarbon impacts are contained on site. Therefore, current and future

16

Closure Request

ARCO Facility No. 6008

inhalation of COCs in outdoor air or indoor air by potential onsite receptors is not considered a potentially complete pathway.

Ecological Receptors

Transport mechanisms potentially leading to the exposure of petroleum hydrocarbons to terrestrial ecological receptors are not considered present at the Site. According to WAC 173-340-7491(1)(a-d), if the Site meets any one of the four exclusion criteria, no further Terrestrial Ecological Evaluation (TEE) is necessary for the Site. A determination was made that the Site met one of the four exclusion criteria (Ecology 2010b). The Site was therefore excluded from further evaluation under the TEE. The exclusion criterion met at the Site includes:

WAC-173-340-7491(1)(c)(i) – “For sites contaminated with hazardous substances other than those specified in (c)(ii) of this subsection, there is less than 1.5 acres of contiguous undeveloped land on the site or within 500 feet of any area of the site.”

The Site is currently paved with asphalt and concrete, and is located in a commercial and residential area of Washougal, Washington.

Since the Site is devoid of ecological habitat and surface water is absent from the Site, it is anticipated that ecological receptors are absent from the Site. It is expected the Site will remain a retail gas station in the future. Therefore, potential exposure pathways for terrestrial ecological receptors are not complete.

Potential Exposure Pathways

Based on the information presented in the previous sections, there are no potentially complete exposure pathways at the Site. Therefore, residual concentrations of petroleum hydrocarbon constituents in soil and groundwater at the Site are unlikely to pose adverse effects to human health and the environment.

Site Clean-Up Levels

Method A Cleanup Levels

The Washington State Department of Ecology issued cleanup levels under MTCA. Method A defines CULs for common hazardous substances such as petroleum hydrocarbons. The MTCA Method A CULs may be used if they meet one of two criteria under WAC-173-340-704:

“Sites undergoing a routine cleanup action as defined in WAC 173-340-200;” or

“Sites where numerical standards are available in this chapter or applicable state and federal laws for all indicator hazardous substances in the media for which the Method A cleanup level is being used.”

According to WAC-173-340-200 routine cleanup actions must meet the following criteria:

“Cleanup standards for each hazardous substance addressed by the cleanup are obvious and undisputed, and allow for an adequate margin of safety for protection of human health and the environment;”

“It involves an obvious and limited choice among cleanup action alternatives and uses an alternative that is reliable, has proven capable of accomplishing cleanup standards, and with which the department has experience;”

“The cleanup action does not require preparation of an environmental impact statement; and”

“The site qualifies under WAC 173-340-7491 for an exclusion from conducting a simplified or site-specific terrestrial ecological evaluation, or if the site qualifies for a simplified ecological evaluation, the evaluation is ended under WAC 173-340-7492(2) or the values in Table 749-2 are used.”

Historic investigations indicate petroleum hydrocarbons are the only COCs in soil and groundwater at the Site, and the Site meets the criteria for undergoing a routine cleanup action. Furthermore, numerical standards for the COCs are available for soil and groundwater under MTCA Method A. Therefore, Method A CULs are appropriate

and were used for the Site. MTCA Method A CULs for COCs at the Site are listed below, according to Table 720-1, Table 740-1 of the MTCA Statute and Regulation:

Groundwater Soils Clean-up Clean-up Criteria Criteria Constituent ( g/L)1,2 Constituent (mg/kg)3 GRO 800 / 1,000 4 GRO 30 / 100 4 DRO 500 Benzene 0.03 Benzene 5 Toluene 7 Toluene 1,000 Ethylbenzene 6 Ethylbenzene 700 Total Xylenes 9 Total Xylenes 1,000

1 Clean-up Criteria based on Washington State MTCA Method A Cleanup Levels for Soils and Groundwater (MTCA Cleanup Regulation 173-340). 2 g/L =micrograms per liter. 3 mg/kg = milligrams per kilogram. 4 Method A Cleanup Levels for GRO are determined based on the presence of benzene.

Groundwater CULs were based on estimates of the highest beneficial use for current and future use at the Site. According to WAC-173-340-720(1)(a), “The department has determined that most sites use of ground water as a source of drinking water is the beneficial use requiring the highest quality of ground water and that exposure to hazardous substances through ingestion of drinking water and other domestic uses represents the reasonable maximum exposure.” Therefore, CULs established under MTCA Method A are protective for the beneficial use of groundwater as a current and/or future potable water source at the Site.

Soil CULs were based on estimates of the reasonable maximum exposure scenario expected to occur given current and/or future use of the Site. According to WAC-173- 340-740(1)(a), “The department has determined that residential land use is generally the site use requiring the most protective cleanup levels and that exposure to hazardous substances under residential land use conditions represents the reasonable maximum exposure scenario.” Therefore, CULs established under MTCA Method A are protective for the maximum exposure scenario for impacted soil, given current and/or future residential land use at the Site.

Points of Compliance

The points of compliance are defined under MTCA as the point or points on a site where the selected cleanup levels are attained. Such points are further divided to include standard and conditional points of compliance. A standard point of compliance requires cleanup levels to be met for every location sampled, and therefore be met throughout the entire Site. A conditional point of compliance requires cleanup levels to be met only at some locations sampled, provided regulatory requirements are met according to WAC 173-340-720 through 173-340-760. Typically, sites that establish a conditional point of compliance place an environmental covenant on the affected properties, thereby limiting future uses of the properties (Ecology 2010b).

Standard points of compliance were established for soil and groundwater at the Site. The soil point of compliance is defined as throughout the soil profile and potentially below the water table across the Site. The vertical and lateral boundaries of the soil point of compliance was designated to the Site based on the protection of groundwater, as outlined in WAC 173-340-740(6)(b). The groundwater point of compliance is defined as throughout the Site, from the uppermost depth of the saturated zone extending vertically to the lowest depth that could potentially be affected by the Site. The vertical and lateral boundaries of the groundwater point of compliance was designated to the Site based on the standard point of compliance for all sites, as outlined in WAC 173-340-720(8)(b).

Applicable Relevant and Appropriate Regulations

According to WAC 173-340-360(2), all cleanup actions under MTCA must comply with applicable state and federal laws. Such laws are defined under MTCA as including applicable relevant and appropriate regulations (ARARs). ARARs for the site include:

Federal

Safe Drinking Water Act (National Primary and Secondary Drinking Water Regulations) (42 U.S.C. 300f, 40 CFR Part 141, 40 CFR Part 143) – Petroleum hydrocarbon cleanup levels are based on the beneficial use of groundwater as a current and/or future potable water source at the Site.

Compliance with MTCA Statutes and Regulations

Soil

Hydrocarbon impacts in soil near the UST basin were removed during excavation and treatment activities.

Historic hydrocarbon impacts in soil near the westernmost dispenser island were limited to surface soil which is covered with asphalt. Hydrocarbon impacts were not detected in deeper soil samples. Additional assessment of the westernmost dispenser island area was conducted in 2011 with the installation of soil borings SB-1 through SB-3. Shallow and deep soil samples were collected on the north, west, and south sides of the westernmost dispenser island. None of the samples analyzed exceeded applicable MTCA Method A CULs.

Grab Groundwater

Hydrocarbon impacts in perched groundwater (SB-3) were limited to TPH-HO and total lead. TPH-HO slightly exceeded the MTCA Method A CUL; however, this detection is mostly likely attributed to common interferences caused by naturally occurring material and organic acids sorbed to the soil that was present in the sample. The sample was turbid and had not cleared after approximately 40 minutes of purging. Petroleum hydrocarbons outside of the gasoline range have not been identified in any other samples collected at the Site.

Surface Waters

No known impacts to surface waters have occurred due to the past operation of the Site as a retail gasoline station. Therefore, this media is considered in compliance with MTCA at the Site.

Sediment

No known impacts to sediments have occurred due to the past operation of the Site as a retail gasoline station. Therefore, this media is considered in compliance with MTCA at the Site.

Soil Vapor

No known impacts to soil vapor have occurred due to the past operation of the Site as a retail gasoline station. Therefore, this media is considered in compliance with MTCA at the Site.

Ecological and Natural Resources

The site qualifies for an exclusion from the TEE according to WAC-173-340-7491, therefore ecological and natural resource related issues at the Site are considered in compliance with MTCA.

Cultural and Archaeological Resources

No known impacts to cultural and archaeological resources have occurred due to retail gasoline station operations at the Site. Therefore cultural and archaeological resource related issues at the Site are considered in compliance with MTCA.

Conclusions

Petroleum impacts on the Site cannot be associated with any specific known event. Various soil and groundwater investigations performed from 1989 to 2011 have delineated petroleum hydrocarbon impacts laterally and vertically. COC impacts above MTCA Method A soil CULs were historically identified in the vicinity, and downgradient from the former UST basin and near the westernmost dispenser island. The current petroleum hydrocarbon impacts in soil and groundwater at the Site are as follows:

• Hydrocarbon impacts in soil from the former UST basin were removed during excavation activities and are no longer present at the Site.

• Hydrocarbon impacts in soil near the westernmost dispenser island were found near the surface during previous investigation activities. During the 2011 site investigation in the area surrounding the westernmost dispenser island, hydrocarbon concentrations in soil did not exceed MTCA Method A CULs.

TPH-HO and total lead exceeded MTCA Method A groundwater CULs in a grab groundwater sample collected from boring SB-3 during the 2011 site investigation. Potential exposure pathways at the Site are either not considered complete or are not considered significant. The former USTs have been removed from the site and are no longer a continuing source of impacts. Impacted soil in the vicinity of the former USTs was excavated and is no longer a continuing source of impacts. Soil samples collected during 2011 site investigation activities to assess impacts near the westernmost dispenser island did not exceed MTCA Method A CULs. TPH-HO detected in the grab groundwater sample is most likely not associated with petroleum but the result of common interferences caused by naturally occurring organic material and organic acids sorbed to the soil that was present in the very turbid sample. The sample turbidity also supports the conclusion that lead was present in the soil and not dissolved into groundwater. Dissolved lead was not detected above laboratory reporting limits in this sample. Petroleum hydrocarbons within the gasoline range previously identified from historical sampling activities were not identified in any of the samples collected during the 2011 site investigation.

The remedial actions completed at the site have eliminated potential on-site sources, including petroleum-impacted soil and former USTs. Groundwater at the Site is not used for potable purposes. There are no domestic water wells or public supply wells identified within 1,000 feet of the Site. Petroleum hydrocarbons within the gasoline range previously identified from historical sampling activities were not identified in any of the samples collected during the 2011 site investigation, including the grab

groundwater sample. Therefore, potential exposures to residual concentrations of petroleum hydrocarbon constituents in soil and groundwater at the Site are not expected to pose adverse effects to human health and the environment.

For the above reasons, ARCADIS requests a determination of No Further Action from the Ecology for the Site.

EDR’s GeoCheck Physical Setting Source Addendum is provided to assist the environmental professional in forming an opinion about the impact of potential contaminant migration.

Assessment of the impact of contaminant migration generally has two principle investigative components:

1. Groundwater flow direction, and 2. Groundwater flow velocity.

Groundwater flow direction may be impacted by surface topography, hydrology, hydrogeology, characteristics of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata.

TC3057259.1s Page 1 GEOCHECK® - PHYSICAL SETTING SOURCE SUMMARY

GROUNDWATER FLOW DIRECTION INFORMATION Groundwater flow direction for a particular site is best determined by a qualified environmental professional using site-specific well data. If such data is not reasonably ascertainable, it may be necessary to rely on other sources of information, such as surface topographic information, hydrologic information, hydrogeologic data collected on nearby properties, and regional groundwater flow information (from deep aquifers).

TOPOGRAPHIC INFORMATION Surface topography may be indicative of the direction of surficial groundwater flow. This information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

HYDROLOGIC INFORMATION Surface water can act as a hydrologic barrier to groundwater flow. Such hydrologic information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

HYDROGEOLOGIC INFORMATION Hydrogeologic information obtained by installation of wells on a specific site can often be an indicator of groundwater flow direction in the immediate area. Such hydrogeologic information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

Site-Specific Hydrogeological Data*: Search Radius: 1.25 miles Status: Not found

AQUIFLOW® Search Radius: 1.000 Mile.

EDR has developed the AQUIFLOW Information System to provide data on the general direction of groundwater flow at specific points. EDR has reviewed reports submitted by environmental professionals to regulatory authorities at select sites and has extracted the date of the report, groundwater flow direction as determined hydrogeologically, and the depth to water table.

GROUNDWATER FLOW VELOCITY INFORMATION Groundwater flow velocity information for a particular site is best determined by a qualified environmental professional using site specific geologic and soil strata data. If such data are not reasonably ascertainable, it may be necessary to rely on other sources of information, including geologic age identification, rock stratigraphic unit and soil characteristics data collected on nearby properties and regional soil information. In general, contaminant plumes move more quickly through sandy-gravelly types of soils than silty-clayey types of soils.

GEOLOGIC INFORMATION IN GENERAL AREA OF TARGET PROPERTY Geologic information can be used by the environmental professional in forming an opinion about the relative speed at which contaminant migration may be occurring.

TOPOGRAPHIC INFORMATION

USGS 7.5’ Digital Elevation Model (DEM) Source: United States Geologic Survey EDR acquired the USGS 7.5’ Digital Elevation Model in 2002 and updated it in 2006. The 7.5 minute DEM corresponds to the USGS 1:24,000- and 1:25,000-scale topographic quadrangle maps. The DEM provides elevation data with consistent elevation units and projection.

HYDROLOGIC INFORMATION

Flood Zone Data: This data, available in select counties across the country, was obtained by EDR in 2003 & 2009 from the Federal Emergency Management Agency (FEMA). Data depicts 100-year and 500-year flood zones as defined by FEMA.

NWI: National Wetlands Inventory. This data, available in select counties across the country, was obtained by EDR in 2002 and 2005 from the U.S. Fish and Wildlife Service.

HYDROGEOLOGIC INFORMATION

AQUIFLOW R Information System Source: EDR proprietary database of groundwater flow information EDR has developed the AQUIFLOW Information System (AIS) to provide data on the general direction of groundwater flow at specific points. EDR has reviewed reports submitted to regulatory authorities at select sites and has extracted the date of the report, hydrogeologically determined groundwater flow direction and depth to water table information.

STATSGO: State Soil Geographic Database Source: Department of Agriculture, Natural Resources Conservation Services The U.S. Department of Agriculture’s (USDA) Natural Resources Conservation Service (NRCS) leads the national Conservation Soil Survey (NCSS) and is responsible for collecting, storing, maintaining and distributing soil survey information for privately owned lands in the United States. A soil map in a soil survey is a representation of soil patterns in a landscape. Soil maps for STATSGO are compiled by generalizing more detailed (SSURGO) soil survey maps.

SSURGO: Soil Survey Geographic Database Source: Department of Agriculture, Natural Resources Conservation Services (NRCS) Telephone: 800-672-5559 SSURGO is the most detailed level of mapping done by the Natural Resources Conservation Services, mapping scales generally range from 1:12,000 to 1:63,360. Field mapping methods using national standards are used to construct the soil maps in the Soil Survey Geographic (SSURGO) database. SSURGO digitizing duplicates the original soil survey maps. This level of mapping is designed for use by landowners, townships and county natural resource planning and management.

A search of available records was conducted by Environmental Data Resources, Inc. (EDR). The EDR Offsite Receptor Report provides information which may be used to comply with the Clean Air Act Risk Management Program 112-R. "The rule requires that you estimate in the RMP residential populations within the circle defined by the endpoint for your worst-case and alternative release scenarios (i.e., the center of the circle is the point of release and the radius is the distance to the endpoint). In addition, you must report in the RMP whether certain types of public receptors and environmental receptors are within the circles."
