The 500-gallon-capacity underground storage tank was ,•1 located on the west side of the City of Tigard facilities building and previously supplied fuel oil to an auxiliary generator at the City of Tigard Police Department. The underground storage tank was decommissioned by removal on August 17th, 2006, according to approved procedures. All waste was appropriately recycled. Soil samples were collected from beneath each end of the tank; petroleum hydrocarbons were not detected in either sample. The excavation was backfilled with crushed gravel, compacted in lifts with the excavator, and capped with stockpiled overburden soil. Recommendations EVREN Northwest Inc. recommends that the regulatory status of this underground storage tank system be updated to 'permanently closed' by the Oregon Department of Environmental Quality and requests that a letter of 'no further action required' be issued. �1 .1 r1 1 1 1 EVREN Northwest, Inc. vi 249-06001-01, Rev.0, 8/24/06 1.0 INTRODUCTION At the request of City of Tigard, EVREN Northwest, Inc. (ENW) has prepared this Underground Storage Tank Decommissioning Report for an underground storage tank (UST) system located at 13125 SW Hall Boulevard in Tigard, Oregon. The 500-gallon-capacity UST was located on the west side of the City of Tigard facilities building and previously supplied fuel oil to an auxiliary generator at the City of Tigard Police Department. 1.1 Purpose In accordance with the stipulations of the proposal dated August 17th, 2006, ENW provided UST decommissioning services as well as UST Decommissioning and Soil Matrix supervision for the project at this site. 1.2 Scope The scope of work (SOW) for this UST decommissioning was as follows: • Perform appropriate notifications to the Oregon Department of Environmental Quality (ODEQ) for the decommissioning project. .1 • Supervise the decommissioning of the five-hundred (500)-gallon-capacity UST; ensuring that decommissioning activities were in accordance with nationally recognized standards of practice. • Collect soil samples from beneath each end of the UST. Analyze the soil samples for petroleum hydrocarbons impacts by method NWTPH-HCID (Northwest total petroleum hydrocarbon identification) at an independent laboratory. • Evaluate the soils underlying the UST to support regulatory closure of the facility with eN respect to ODEQ UST Regulations. � �"1 • Prepare this report documenting the decommissioning activities. ENW performed the decommissioning activities described in this report on August 17, 2006. r1 EVREN Northwest, Inc. 1 249-06001-01, Rev. 0, 8/24/06 ^'1 2.0 SITE SETTING 2.1 Description and Location The City of Tigard Police Department.facility is located at 13125 SW Hall Boulevard in Tigard, Oregon (see Figure 1). The site is developed with the City of Tigard's municipal offices, and also includes paved parking areas and landscaped grounds. The UST was located under a lawn area adjacent to a sidewalk (Figure 2). ^, 2.2 Topography The site is level. The US Geological Survey Beaverton Quadrangle map indicates that the site is located at an approximate elevation of 160-feet above mean sea level with a very gentle slope toward Fanno Creek, immediately south of the property. 2.3 Geologic Setting 2.3.1 Regional Geology The subject property is located in the eastern Tualatin River Basin of northwestern Oregon. The Tualatin River Basin is a structural depression between the Chehalem Hills to the south, Oregon Coast Range to the west and Tualatin Mountains and Portland Hills to the northeast and east. The erosional and depositional alluvial processes of the Tualatin River and its tributary streams have modified the structural depression of the basin. In addition, during late ,.` Pleistocene time (approximately 12,000-years before present), numerous catastrophic floods ^ (Missoula Floods) backwashed into the Tualatin River Basin from the Willamette Valley to the east, depositing large volumes of sediment throughout the Basin due to damming of flood waters within the basin prior to being released to down-gradient areas. The subject site is located on silt and fine sand deposited by the flood events. 2.3.2 Site Geology ,.� The excavation penetrated fine silts to the maximum depth of excavation of approximately eight (8) feet. Isopach mapping of the sediments above the basement bedrock suggests that the flood sediments are over 400-feet thick in this area.'. r'1 '1 2.4 Hydrogeologic Setting 2.4.1 Surface Water No surface water bodies are present on the subject property; however Fanno Creek is located approximately 500-feet to the south. Madin, I.P., 1990,Earthquake-hazard geology maps of the Portland Metropolitan Area,Oregon: Oregon Department of Geology and Mineral Industries,Open-file Report 0-90-2, 1:24,000 maps with text. EVREN Northwest, Inc. 2 249-06001-01, Rev.0,8/24/06 2.4.2 Ground Water Depth to ground water was not determined during this SOW. However, ENW accessed the Oregon Water Resources Department Grid Database to determine ground-water conditions in the vicinity of the subject site. Well logs in the database indicate depth to static ground-water level in nearby wells is at less than fifteen (15) feet in this area (Appendix A), consistent with the presence of Fanno Creek on the south side of the City's municipal offices property. Ground- water flow direction should be toward the south, based on the topographic gradient and the presence of Fanno Creek, which is a regional drainage feature in this area. e n "1 r'1 .�1 r1 10"1 r� '1 r1 EVREN Northwest, Inc. 3 249-06001-01, Rev.0,8/24/06 3.0 SITE INVESTIGATION METHODS AND PROCEDURES The UST-decommissioning project was performed with the following specific objectives: • Perform the decommissioning project in an efficient and cost-effective manner while satisfying the requirements of our client. • Ensure that the decommissioning of the UST was in accordance with State and local administrative standards. • Ensure that any existing information or data incorporated into work to be performed under this SOW is certifiable and valid for the intended use. 1 All field activities were photographically logged (Appendix B). The following sections describe the various fieldwork activities. 3.1 Underground Storage Tank Decommissioning Decommissioning of the USTs system was based on the procedures referenced in the following documents: 1. American Petroleum Institute (API) 2015, "Cleaning Petroleum Storage Tanks," 1994. 2. ODEQ, "Cleanup Rules for Leaking Petroleum UST Systems," November 1998. 001 The top of the tank was exposed by excavation and the product lines were drained. Fuel remaining in the UST and product line was pumped by a pump-truck operated by Oil Re- Refining Company (ORRCO). The non-explosive condition of the tank was verified with an organic vapor monitor before cutting open the tank. Once the tank was ventilated, ORRCO pressure washed the interior and removed all sludge and rinsate. When the tank was clean, the tank was excavated and removed. The tank's condition was inspected by a state-licensed ^ Soil Matrix/Decommissioning supervisor and then the decommissioned UST was loaded onto a truck for off-site disposal. Required ODEQ report forms and checklists were completed as part of this project (Appendix C). 3.2 Soil Sampling OON Assessment soil samples were collected from freshly excavated soils within two (2)-feet of the OON bottom of the tank (Figure 3). It was noted that the tank was underlain with approximately one look. (1) foot of crushed gravel backfill and a concrete deadman. Therefore assessment samples were collected from silty soil excavated at the ends of the deadman. The samples were promptly transferred with clean Nitrile gloves to appropriate laboratory-supplied sample --, containers. Headspace within the containers was minimized before sealing. The samples were then labeled with a distinctive designation and placed in cooled storage until delivered to the laboratory. EVREN Northwest, Inc. 4 249-06001-01, Rev. 0, 8/24/06 Chain-of-custody protocols were implemented for all soil samples. Laboratory analytical reports are presented in Appendix D. 3.4 Waste Management ,y Residual product and rinsate pumped from the UST were removed from the site for off-site recycling by ORRCO. The tank was taken to Metro Metals in Portland, Oregon, for recycling. Waste receipts are included in Appendix E. '1 3.5 Soil Matrix Cleanup Regulation ODEQ permits "simple" contamination sites to be cleaned up by setting standards based on site 10N conditions. "Simple" sites are defined as those sites where only a limited volume of soil .-� contamination is present, where there are no significant threats to human health and safety, and where ground water, surface water, or sensitive environments are not impacted or likely to "ONbe impacted. The standards are specified in the Soil Matrix Cleanup Rules (Oregon Administrative Rules 340-122-360). The Soil Matrix Cleanup Levels are determined for the site by inputting environmental parameters with site-specific values. The values used in determining the soil matrix cleanup level for a site are: r1 • Annual rainfall • Soil type • Sensitivity of the uppermost aquifer • Depth to ground water • Distance to nearest potential receptors • Number of potential receptors Soil Matrix Cleanup Level II was determined to be appropriate for the site. The required Soil Matrix Checklist and Scoresheet have been completed as part of this decommissioning project .s.

EVREN Northwest, Inc. 6 249-06001-01, Rev.0, 8/24/06 5.0 CONCLUSIONS AND RECOMMENDATIONS 5.1 Conclusions The UST was decommissioned by removal according to approved procedures. All waste has been appropriately recycled. Soil samples were collected from beneath each end of the tank; petroleum hydrocarbons were not detected in either sample. The excavation was backfilled with crushed gravel, compacted in lifts with the excavator and capped with stockpiled overburden soil. 5.2 Recommendations ENW recommends that the regulatory status of this UST system be updated to `permanently closed' by the ODEQ and requests that a letter of 'no further action required' be issued. EVREN Northwest, Inc. 7 249-06001-01, Rev.0,8/24/06 0''1 .1 6.0 LIMITATIONS The scope of this report is limited to observations made during on-site work; interviews with 1 knowledgeable sources; and review of readily available published and unpublished reports and 1 literature. As a result, these conclusions are based on information supplied by others as well as 1 interpretations by qualified parties. The focus of the site closure does not extend to the presence of the following conditions unless they were the express concerns of contacted personnel, report and literature authors or the work scope. 1. Naturally occurring toxic or hazardous substances in the subsurface soils, geology and water, 2. Toxicity of substances common in current habitable environments, such as stored chemicals, products, building materials and consumables, 3. Contaminants or contaminant concentrations that are not a concern now but may be _ under future regulatory standards, 4. Unpredictable events that may occur after our site visit, such as illegal dumping or accidental spillage. �v There is no practice that is thorough enough to absolutely identify the presence of all hazardous substances that may be present at a given site. ENW's investigation has been focused only on the potential for contamination that was specifically identified in the scope of work. Therefore, if contamination other than that specifically mentioned is present and not identified as part of a �1 limited scope of work, ENW's environmental investigation shall not be construed as a A"h guaranteed absence of such materials. ENW has endeavored to collect representative 001 analytical samples for the locations and depths indicated in this report. However, no sampling program can thoroughly identify all variations in contaminant distribution. We have performed our services for this project in accordance with our agreement and A"NI understanding with the City of Tigard. This document and the information contained herein have been prepared solely for the use of City of Tigard. 001 ENW performed this study under a limited scope of services per our agreement. It is possible, 01 despite the use of reasonable care and interpretation that ENW may have failed to identify regulation violations related to the presence of hazardous substances other than those eN specifically mentioned at the closure site. ENW assumes no responsibility for conditions that we did not specifically evaluate or conditions that were not generally recognized as environmentally unacceptable at the time this report was prepared.
