This technical memorandum was prepared in response to a request from the Oregon Department of Environmental Quality (DEQ) for an updated beneficial land and water use determination for the Union Pacific Railroad (UPRR) Hinkle Rail Yard located in Hermiston, Oregon. The beneficial land and water use determination was updated using the following criteria as outlined in OAR 340-122: • Review current and reasonably anticipated future land use in the locality of facility; including current and future zoning, local comprehensive and development plans, and other land use designations (OAR 340-122-080(3)(e)). • Review information related to the current and likely future beneficial uses of groundwater and surface water (OAR 340-122-080(3)(f)). Considering federal, state, and local regulations governing the appropriation and/or use of water; Nature and extent of current groundwater and surface water uses; Suitability of groundwater and surface water for beneficial uses; The contribution of water to the maintenance of aquatic or terrestrial habitat; and Reasonably likely future uses of groundwater • Identify hazardous substances having significant adverse effects on beneficial uses of water (OAR 340-122-080(6) • Evaluate site risk and possible human exposures and significant adverse effect on ecological receptors (OAR 340-122-084(1) • Evaluate the feasibility of reasonable treatments needed to restore or protect beneficial uses of water within a reasonable timeframe (OAR 340-122-085(5) Introduction The UPRR Hinkle Railyard is located in a rural portion of Umatilla County, approximately 3 miles south of Hermiston, Oregon (Figure 1). The Railyard property lies between railroad mile post (MP) 182.1 of the Portland Subdivision and MP 188.6 of the Nampa Subdivision on the Columbia River service unit in northeastern Oregon. The entire UPRR Hinkle Railyard property encompasses approximately 2,755 acres and trends east to west covering a distance of over 4 miles. The active locomotive fueling facility and locomotive service platform are located in the western portion of the railyard in the southeast quarter of Section 27, Township 4 North, Range 28 East. The Umatilla River flows parallel to the railyard and is

EN0929161114PDX 1 UPDATED BENEFICIAL LAND AND WATER USE DETERMINATION, UPRR HINKLE RAIL YARD, HERMISTON, OREGON located approximately 0.25 mile south of the Hinkle Railyard. Interstate 84 also parallels the railyard and is located approximately 1 mile to the south. Hydrogeologic Site Characterization This section presents the hydrogeologic setting within the locality of facility at the Hinkle Railyard. Locality of the Facility The first step in establishing the groundwater beneficial use for the Hinkle Railyard is to establish the locality of facility (LOF). Section OAR 340-122-115(34) of the DEQ Cleanup Regulations define “Locality of Facility” as: Any point where human or an ecological receptor contacts or is reasonably likely to come into contact with facility-related hazardous substances. The LOF is established on a site-specific basis considering the following: • The nature and extent of contamination • The potential contaminant migratory pathways considering the conceptual site hydrogeologic model • The potential human and environmental exposure points on, and around, the site that may be impacted given the above two factors The 2002 beneficial use determination defined the LOF as the UPRR property and the northern portion of the J.R. Simplot Company (Simplot) property located to the south of the Railyard, on the basis of the nature and extent of total petroleum hydrocarbons-diesel (TPH-d) as defined in the Remedial Investigation (RI) Report (CH2M, 2002). Vertically, facility-related constituents are limited to the uppermost unconfined water-bearing zone. The nature and extent of the dissolved-phase plume defined in the RI Report has been monitored by analyzing annual groundwater samples in AOI 1 for TPH-d since 2002 and monitored natural attenuation parameters since 2010. Based on the groundwater monitoring results the nature and extent has remained consistent with the 2002 evaluation as shown on Figure 2. Additional wells A1MW-20 and A1MW-21, located on the northern boundary of the railyard property line in AOI 1, were installed in 2006. Since being installed, TPH-d has occasionally been detected in these wells. Although dissolved phase TPH-d is present along the UPRR downgradient property boundary, the 5-year Record of Decision review evaluated the stability of the plume and the potential for further migration. Based on this evaluation it was determined that the plume does not appear to be moving beyond its current footprint. Two wells (SPMW-10S and SPMW-10D) installed to the south of the railyard within the Simplot property boundary have detections of TPH-d that exceed the risk-based concentration for occupational exposure (DEQ, 2015). TPH-d has been detected at SPMW-10S since 2002 at concentrations ranging from non- detect to 3.48 milligrams per liter and at SPMW-10D from non-detect to 1.99 milligrams per liter. As described in this technical memorandum, site-related constituents are not expected to migrate to underlying aquifers. Consequently, the LOF is limited to the uppermost unconfined alluvial water- bearing zone within the geographic footprint noted above. As requested by DEQ, an Easement and Equitable Servitude restricting groundwater use in the LOF on the UPRR Hinkle Railyard was filed with the Umatilla County Assessment and Taxation Office in 2009. The extent of the deed-restricted area for AOI-1 is shown on Figure 3 Conceptual Site Model The conceptual site model (CSM) is used to describe the relationships between the chemicals of concern and potentially exposed human receptor populations. The CSM determines the relationships between the suspected sources of chemicals of concern, the release and transport mechanisms in the

2 EN0929161114PDX UPDATED BENEFICIAL LAND AND WATER USE DETERMINATION, UPRR HINKLE RAIL YARD, HERMISTON, OREGON environment, and the potential exposure routes. A conceptual site model was previously developed as part of the RI Report (CH2M, 2002) and is summarized here. Figure 4 presents a schematic representation of the conceptual model for the Hinkle Railyard. The simplified model depicts the unconfined water-bearing zone in sand and gravel, and silt, which overlays the siltstone aquitard. Recharge to the unconfined water-bearing zone occurs from the Umatilla River and from irrigation within the Umatilla River floodplain. Petroleum light nonaqueous phase liquid (LNAPL) has been observed at certain locations in the unconfined water-bearing zone in AOI 1 and AOI 5. The LNAPL is believed to originate from the former Diesel Platform and former leaky underground storage tanks in AOI 1, and the former Waste Oil Lagoons in AOI 5. The dissolved phase petroleum plume has migrated to the west, following the groundwater flow direction. It is expected that both physical and biological processes attenuate hydrocarbons, slowing or arresting the dissolved phase migration. Natural attenuation parameters dissolved iron and manganese, methane, carbon dioxide, total nitrate, and sulfate have been analyzed in AOI 1 monitoring wells since 2010. The natural attenuation data for A1MW-10, SPMW-10S, SPMW-58, and SPMW-59 provide evidence of anaerobic biodegradation within the dissolved plume. The Umatilla River is not believed to be a potential receptor of contaminants from the Hinkle Railyard, because the river loses water to the unconfined water-bearing zone and the dissolved phase petroleum plume is not expected to migrate as far as the river. Stormwater runoff and drips from locomotive fueling and maintenance activities are contained at the Hinkle Railyard and treated at the wastewater treatment plant and then sent to the lined evaporation ponds, so contaminated surface runoff from the railyard is not expected to impact the river. Based on current and potential future land use and groundwater beneficial uses, discussed later in this technical memorandum, identified for the site, potentially complete exposure pathways exist for the following exposure routes in groundwater: • Ingestion, dermal contact, and inhalation of vapors while showering for current and future onsite workers • Ingestion, dermal contact, and inhalation of vapors while showering for current and future residents To address the petroleum hydrocarbons in groundwater within the LOF, the following remedial action objective for groundwater was developed:

• Prevent offsite residential and onsite occupational worker exposure to constituents present in groundwater. However, the risk assessment conducted as part of the RI report (CH2M, 2002) did not identify excess risk associated with the constituents detected in groundwater in the absence of LNAPL. Regional Hydrogeology Regional hydrogeology was previously described in detail in the RI Report (CH2M, 2002) and summarized here. The Hinkle Railyard site is located within the Umatilla Basin of the Columbia Plateau physiographic province and is sub-regionally located in the northern Butter Creek alluvial floodplain. The primary geologic unit in the region is the Columbia River Basalt Group. Overlying the basalt flows are a series of interbedded catastrophic flood deposits. Overlying the catastrophic flood deposits are a series of Holocene alluvial sediments consisting of reworked soils, catastrophic flood deposits and basaltic gravels.

EN0929161114PDX 3 UPDATED BENEFICIAL LAND AND WATER USE DETERMINATION, UPRR HINKLE RAIL YARD, HERMISTON, OREGON The Columbia River Basalt is the principal aquifer over an area of as much as 50,000 square miles. The predominant water-bearing zones in the basalt sequence occur in fractures and joints, scoriaceous fractured interflow zones, and sedimentary interbeds separating individual basalt flows. Vertical permeability tends to be restricted within the interior of each flow, which creates distinct confined and semi-confined aquifers (Robison, 1971). Near the site, recharge to the basalt aquifer is limited but may occur in localized areas due to infiltration where basalt flows have been exposed in upland areas. Regionally, the Alluvial Aquifer overlying the basalt is variable and limited in both thickness and lateral extent. The limited thickness of the saturated alluvium restricts water supply development in the immediate vicinity of the Hinkle Railyard. Where the alluvium extends below the potentiometric surface (water table), this aquifer is capable of yielding moderate to large quantities of water. The Alluvial Aquifer is recharged directly by precipitation, irrigation, canal seepage losses, and by percolation of streamflow. Due to the limited saturated thickness, the Alluvial Aquifer is not considered a regionally important aquifer (Hogenson, 1964). Hydrogeology in the Locality of the Facility Hydrogeology in the LOF is described in detail in the RI Report (CH2M, 2002) and summarized in this section. The local hydrogeology of the Hinkle Railyard is relatively complex. This is a result of both spatial variations in lithology and corresponding hydraulic conductivity relating to the complex glaciofluvial depositional environment of the alluvium and the presence of surface water and hydrologic recharge features that exert a strong influence on water levels and groundwater flow. In the western portion of the site, the shallow groundwater table occurs in the coarse sand and gravel unconfined water-bearing zone at approximately 105 to 125 feet below ground surface (bgs). The direction of groundwater flow is to the west-northwest. In the eastern portion of the site, the shallow groundwater table occurs in a clay- rich silt layer at approximately 60 to 65 feet bgs. The direction of groundwater flow is to the west- northwest. Areal Recharge Several potential sources for areal recharge south of AOI 1 include the Umatilla River, ephemeral drains, wastewater ponds, and irrigated fields in the floodplain. The Umatilla River is just south of the railyard and flows generally to the west with a slight northern trend. The river stage and groundwater levels in the river floodplain are higher than groundwater levels measured in the surrounding alluvial deposits, indicating that near the Rail Yard, the Umatilla River is a losing stream and provides recharge to the unconfined water-bearing zone. There are several linear ephemeral drains and ponds paralleling the river between the floodplain and the western portion of the railyard (AOI 1). These features collect rainwater and snowmelt runoff from the steep bluff and channel it into the small ponds, where a small fraction probably reaches the shallow groundwater. Simplot irrigates fields in the Umatilla River floodplain just south of AOI 1. Two wells (Well-4 and Well-6) completed in the Columbia River Basalt Group are used for irrigation of these fields. Between the two wells Simplot is typically allotted 70 acre feet or 23 million gallons of water per year for irrigation purposes. These wells are installed in the Columbia River Basalt Group between 700 and 1,000 feet bgs. Only one well is pumped at a time. Recharge near the eastern portion of the Rail Yard (near AOI 5) originates from the Umatilla River and seepage from the Feed Canal irrigation ditch. The Feed Canal irrigation ditch is empty most of the year.

4 EN0929161114PDX UPDATED BENEFICIAL LAND AND WATER USE DETERMINATION, UPRR HINKLE RAIL YARD, HERMISTON, OREGON Areal Discharge Simplot occasionally uses a well completed in the unconfined water-bearing zone (Well 3) for domestic purposes. Water from this well is used for sinks, toilets and occasionally as dilution water for fertilizers. Information on the rate of water use is currently unavailable. Other wells in the area are screened in the basalt aquifer, which has little to no hydraulic connection to the unconfined water-bearing zone. Identification of Potential Beneficial Water Uses The following sections describe the historical, current, and reasonably likely future land uses and current zoning for the LOF. Land use was assessed based on the following sources: • Umatilla County Comprehensive Plan • Umatilla County land use maps, including map for Stanfield Historical Land Uses Industrial land use in Umatilla County historically has been tied to agriculture and forestry. UPRR acquired the Hinkle Railyard property in 1950. Fueling, maintenance and car cleaning operations began on-site in approximately 1951. Prior to that it is believed that the site was used for agriculture (UPRR, 1997). Current Land Uses The land in the LOF currently is zoned for industrial use (Figure 5) and is occupied by the Hinkle Railyard, which includes repair facilities for rail cars, administrative offices, several railroad tracks leading to the rail classification yard on the eastern portion of the site, and fueling facilities. This facility is a major transportation consideration in Umatilla County and is one of the largest such facilities in the western United States. Car trains are made up at the Hinkle Railyard for general routing along the UPRR system. The presence of this rail facility makes the entire western portion of Umatilla County ideal for industrial users who need rail infrastructure. Current land uses to the North and South of AOI 1 are a mix of agricultural and industrial. Future Land Uses UPRR will continue to use the facility into the future as a significant rail yard for the northern mainline. It is expected that the land will continue to be zoned as industrial in the future. The Umatilla County Comprehensive Plan (Umatilla County Planning Department, 2014) has committed additional land to the north of the railyard to be zoned for industrial use (Figure 5). These properties to be developed as industrial sites currently are owned by UPRR and Pendleton Grain Growers. Umatilla County believes that this area has been sufficiently demonstrated to be a developing rural industrial area. Currently, electricity, gas, and telephone facilities are available. The properties are adjacent to land within the urban growth boundary, and municipal water may be available. UPRR, which owns much of this property, has developed its own water system for its facilities, which obtains groundwater from three water wells completed in the Columbia River Basalt Aquifer. The major rail facility and agricultural related industrial development at Hinkle provides a large impetus for further industrial development (Umatilla County Planning Department, 1983, Revision Date: December 3, 2014). Future uses of the adjacent property is expected to remain agricultural. Simplot does not expect water use from the large production wells completed in the Columbia River Basalt Group to increase beyond the maximum irrigation allotment of 100 acre feet (33 million gallons).

EN0929161114PDX 5 UPDATED BENEFICIAL LAND AND WATER USE DETERMINATION, UPRR HINKLE RAIL YARD, HERMISTON, OREGON Evaluation of Beneficial Uses of Water This section presents the current and future beneficial uses of water in the alluvial water-bearing zone within the LOF. Current Beneficial Water Uses The historical and current beneficial use of water within the LOF was assessed based on the following sources: • Groundwater wells currently in existence within and around the LOF • Review of the Umatilla County Comprehensive Plan The beneficial use of water is any current or reasonably likely future use by humans or ecological receptors of groundwater or surface water. A groundwater well search of the Oregon Water Resource Department well database was completed for wells located within approximately 1 mile of the Hinkle Railyard. A total of 132 wells were identified (Attachment 1), of which 77 are water wells and 55 are monitoring wells. Of the 77 water wells, 50 are completed in the alluvial water-bearing zone. These well logs are provided in Appendix C of the RI Report (CH2M, 2002). Figure 6 shows the locations of the water wells differentiating between wells completed within the alluvium and wells completed within the basalt. UPRR uses three railyard water wells for both industrial use and drinking water. These three water wells are completed within the basalt. Hinkle Well-1 is located within AOI-1 but is installed to a depth of 547 feet bgs. The pumping rate from this well is not known. No water wells screened in the alluvium or basalt were identified in AOI-5. The beneficial use of groundwater within the alluvium is for irrigation, livestock, and domestic and industrial applications. Only one well screened in the alluvium in the LOF of the Hinkle Railyard is used for industrial purposes. The well (Well-3), installed to a depth of 230 feet, is located on the Simplot property near the main building (approximately 700 feet cross gradient from SPMW-10S) and is currently used for a mixture of domestic and industrial purposes. Because of the proximity to SPMW-10S Well3 was sampled for NWTPH-Dx and polycyclic aromatic hydrocarbons on September 13, 2016. No hydrocarbons were detected above laboratory reporting limits. The laboratory report is provided in Attachment 2. located outside of the LOF, are present on the Simplot property. These wells are located to the west along Highway 207 and are installed to approximately 150 feet bgs. The wells supply water for domestic use to the Hermiston Power LLC gas-fired electrical generating facility, the Simplot office and irrigation for trees along the Simplot entrance road. Yields from these three wells are up to 125 gallons per minute. Groundwater contour maps prepared for the annual groundwater monitoring reports do not indicate that groundwater flow within the LOF is not influenced by water use in the alluvium. Figure 7 presents the location of Simplot wells in relation to the Hinkle Railyard monitoring wells. The other 49 wells, completed within the alluvium, are located outside of the LOF but within 1 mile of the site. These wells are used for livestock watering, irrigation, domestic and industrial applications. Two wells (Well-4 and Well-6) completed in the basalt aquifer are located on the Simplot property. These wells are used for irrigation of livestock feed crops on the southern portion of the Simplot property adjacent to the Umatilla River. Between the two wells Simplot is typically allotted 70 acre feet or 23 million gallons of water per year for irrigation purposes. These wells are installed in the Columbia River Basalt aquifer to 985 and 1,042 feet bgs. Wells are sealed from ground surface to 162 and 187 feet, respectively, preventing alluvial water from entering the well. Reasonably Likely Future Beneficial Water Uses The reasonably likely future beneficial use of water within the LOF was assessed through the following sources:

• Land use zoning • Interviews with Simplot and UPRR personnel The land use zoning maps show that the use within the area will continue to be industrial and agricultural. Through discussions with Simplot and UPRR personnel, CH2M understands that Simplot plan to continue to use their four water wells completed in the alluvial aquifer for industrial and drinking water uses. It is expected that the beneficial use will remain similar to current beneficial use into the foreseeable future. References CH2M HILL (CH2M). 2002.
