October 26, 2017 2642 Michael McBreen, General Manager Columbia Asphalt & Ready-Mix 377 Parker Bridge Road Wapato, WA, 98951 Preliminary Geotechnical Assessment of Recent Ground Movement Columbia AK Anderson Quarry Parker, Washington Dear Mr. McBreen: Cornforth Consultants, Inc. (Cornforth) has been retained by Columbia Asphalt and Ready Mix (Columbia) to provide a preliminary assessment of the recently discovered ground movements at the Columbia AK Anderson quarry (AK Anderson). We have completed our preliminary assessment and this letter-report provides preliminary conclusions and recommendations regarding landslide mechanisms and impacts to the existing and potential quarry operations. Introduction and Background AK Anderson is located south of Yakima, WA (Figure 1), on the southwest side of Union Gap, where the Yakima River flows southward through a gap in the east-west trending Ahtanum Ridge and Rattlesnake Hills. On or around October 2, 2017, Columbia was alerted to the presence of ground cracks up slope and north of the quarry. Cornforth was requested to visit and provide an opinion and initial recommendations, which was performed on October 5. Initial reconnaissance was performed by Charlie Hammond, accompanied by Jerry Browser of Columbia, to develop a preliminary understanding of the scale and direction of ground movements, and to review short-term options. Washington DNR representatives were also onsite October 5, including Rian Skov and Bryan Massey. Columbia voluntarily suspended excavating materials from the north side of the quarry. Initial Discussion Initial opinions discussed on October 5 with Columbia included that the ground movement and associated cracks and fissures appeared to be associated with deep-seated landslide movement on the relatively gentle south-facing slope on the north side of the quarry. The area of movement is sketched on a site aerial image and a topography map, reproduced as Figures 2 and 3, respectively. The movement was approximately 1 to 2 feet vertical and 2 to 3 feet horizontal, and generally toward the south. Tension and settlement has occurred to the west side of a prominent north-south fissure zone (Figure 4) over an elongated swath, approximately 1,000 feet north-south and 150 to 250 feet wide 2642 (Figure 2). The swath contains numerous tensional and shear fissures. The primary movement across the north-south fissure zone is left-lateral, the west side to the south. Since the north-south fissure aligned with a fracture in the quarry rock exposed in the northeast corner of the quarry highwall (Figure 2), the movement appears to be associated with high angle fractures. The base and toe of the slide movement was not readily evident, and is presumed to be associated with a deeper fault zone and/or sedimentary interbed within the Columbia River Basalt (CRB). Initial observation of movements within the slide mass indicated a component of westward movement; however, this appears to be isolated within the upslope area of ground fissures, where the north-south fissure extends into the westfacing slope (Figures 2 and 5). In addition, fissures that occur lower on the west-facing slope were observed to include a component of tensional movement toward the south (Figure 5).

October 26, 2017 2 Cornforth Consultants, Inc. 2642 A second visit was performed by Charlie Hammond, Cornforth, and Jerry Bowser, Columbia, on October 16 to collect additional information on surficial ground movements and the site’s geologic materials. Geology Background The quarry and ground movements are on the south flank of the Rattlesnake hills, an anticlinal fold in the Columbia River Basalt Formation (CRB). The trend of the anticline fold is generally east-west, and the flanks of the fold dip north and south. The folded rock formations that are visible at the ground surface include Saddle Mountains Basalt and Wanapum Basalt of the CRB, which are also mapped (Bentley et al, 1993) including interbedded sedimentary rocks of the Ellensburg Formation. Overall the structural dip of the bedding near the quarry has been mapped at 14 to 20 degrees to the south-southwest, approximately Azimuth direction of 185 to 190 degrees. A sedimentary interbed, which daylights near the base of the west side of the quarry, was measured during our October 5th reconnaissance with a dip of 10 degrees toward Azimuth direction 190 degrees. Quarry rock in the highwall (Figure 6) is primarily the Saddle Mountains Basalt, which is the entablature upper portion of a CRB lava flow. At the quarry the entablature is highly to moderately jointed (spacing commonly 3- to 18-inches) forming slender columns in near vertical, wavy and fanning patterns. Fractures also occur in the rock formation (Figure 6). They appear continuous through the rock formation, as singular fractures or multiple near-parallel fractures, and with spacing the varies from moderate to wide (<1-foot to >10s of feet). Fracture trends are generally northnorthwest to north, and with dips that are vertical to steep (>70°). Joints and fractures are tight to open and with minor secondary mineralization in the fractured zones. The rock is reported to be rippable with dozer. The lower portion of a CRB lava flow often contains wider spaced jointing, typically described as colonnade. This type of jointing was observed at low elevations near the west side floor of the quarry. Groundwater, such as springs or seeps, was not observed during our reconnaissance; however, reconnaissance did not include all areas of the quarry. Columbia personnel allege that their operation has not encountered groundwater in excavations. Tectonic faults mapped in the region around the quarry include generally east-west-trending normal faults near the crest of the anticlinal fold (the overall east-west ridgeline), and a south-verging thrust fault located low on the slopes of the anticline’s south flank. The normal faults appear to represent the north and south sides of a tensional zone within the crest of the anticlinal fold, and with fault displacement that terminates with depth in the layers of CRB (exposed on the west-facing slope of Union Gap). Portions of the faults are mapped with dashes and queries, which indicates approximation and uncertainty, respectively, in the mapping. Fractures in the quarry rock are likely to have developed concurrent with tectonic faulting and folding. Landslide Movement Interpretation Aerial photo and topography maps (Figures 2 and 3) and two cross sections (Figure 7) illustrate an interpretation of the ground movements. Cross section A-A’ is oriented north-south and is October 26, 2017 3 Cornforth Consultants, Inc. 2642 approximately 100 feet west of the main north-south fissure zone. Cross section B-B is oriented eastwest and is approximately 100 feet north of the quarry highwall. To the east the apparent limit of the ground movement is visible as the prominent north-south fissure zone (Figures 2, 4 and 7). To the north the apparent limit is the northern most extension of the northsouth fissure (Figures 2 and 7). A landslide “graben” appears to occur west of the northern extension, and north of a splay in the main fissure on the south side of the ridge line (Figure 2). The western limit appears to be delineated by different features. At the north end, near elevation 1,300 feet on the west-facing slope, is a western limit of fissures that step down the slope to the west and south. At the south end, a western limit appears to be a series of high angle, near parallel fractures through basalt in the quarries highwall. The fractures trend approximately west-northwest and a dip of approximately 80 degrees to the east-northeast (dip degrees/dip Azimuth direction = 80/070). A line drawn between these northern and southern points is roughly coincidental with the observed western limit of fissures in the ground surface. To the south, the apparent limit of ground movement is the quarry; however, the specific location of a slide toe within the quarry has not been identified yet. It appears to be within an area of recent excavation (see Figures 2 and 6). No ground movements were observed to be associated with an exposure of the sedimentary interbed in the quarry west wall; however, detailed crack mapping and additional investigation of the changing conditions is recommended to further delimit the ground movements. Landslide deposits are mapped in available geologic reports to the north and west of AK Anderson, but not within the quarry property (Bentley et al. 1993; Campbell 1976). However, re-assessment of geologic maps and slope shading imagery from the LiDAR data indicates that ancient landslide features may also occur within the property (Figure 8). Normal faults a few hundred feet upslope and north of the Columbia property and the thrust fault to the south are suspiciously coincident with the head graben of a translated landslide (down dropped area between parallel normal faults) and the toe of a paleolandslide (geologically ancient). A preliminary assumption could be that a massive slide or series of slides on the south flank of the Rattlesnake Hills anticline may have occurred during a prior geologic environment. The suspect paleo-landslide may have translated in a downdip direction (generally southward) on a sedimentary layer of the Ellensburg Formation, such as the Mabton Member or the deeper Squaw Creek Member. This interpretation has not been verified by investigation, but the recent ground movements appear to be that of a deep-seated translational landslide that moved on a combination of pre-existing faults and fracture zones, and possibly an interbed. At the northern limit of slide movement in the graben area, the ground surface elevation decreases and slopes off to the west, and it appears that the slide mass likely decreases in volume (i.e., decreases in load). From the surface exposures of fractures in the quarry highwall, and the trend of the main northsouth fissure, the western and eastern limits of movement appear to converge to the south. Recent quarrying within the convergence area may have removed weight from within a “wedge” of rock, allowing a basal slide zone (possibly along a relatively weak layer of sedimentary rock) to arch or step up through basalt toward the recent excavation. Relatively high strength of the CRB rock combined October 26, 2017 4 Cornforth Consultants, Inc. 2642 with an apparent converging or narrowing toe of the wedge may be providing some resistance against continued or more rapid slide movement. Based on our experience, translating rock block landslides overlying a pre-existing relatively weak zone that dips at angles in the range of 10-20 degrees have a tendency to move relatively slowly, possibly continuously or as multiple small lurches. If the basal shear zone was not pre-existing and the movement was a first-time failure, it’s possible that more significant or catastrophic movements may have occurred. A slow translating block slide may move for long periods of time until it reaches a state of balance or is mitigated against further movement. The rate, or changing rate of movement may also be associated with the level or changing level of landslide stability, i.e., increasing rates equate to decreasing stability and vice versa. Seismic activity from earthquakes or blasting may possibly increase the rate of movement. Rapid failure mechanism within such slides would tend to consist of rock falls from over steep and fracturing rock slope, or weakened soil and rock slopes that are disturbed and out of balance in their stability. While slide movement is occurring, it is unlikely that large catastrophic failures will. Short-Term Monitoring Short-term monitoring has been deployed by Columbia using a GPS-based system to relocate painted marks (temporary hubs) on the ground surface. Measurements of the hubs dispersed across the area of ground cracks initiated on a daily basis, and are currently being taken three times per week. Results of weekly monitoring data from October 4 to 23 are provided in Appendix A, including preliminary assessments of the data. In general, the slide mass appears to be moving toward the south at a rate that varies from 0.02 to 0.07 feet per day (1.7 to 6 inches per week). Most of the up slope area on the westfacing slope appears to be moving 0.02 feet per day or less. Rates higher than 0.07 feet per day are interpreted to be associated with settlement near fissures. The rate of movement appears to have been relatively constant during the monitoring period this month. The apparent direction of slide movement has been generally to the south; however, the graben block has a component of westerly movement and is exhibiting vector movement to the southwest. The slope vector movement is highly variable, and appears to be generally between 5 and 22 degrees. Higher vector slope angles, and the variability in the vector slope angles, is interpreted to be due to settlement near fissures. Methods to monitor ground movement in the likely toe area are being evaluated. Recommendations The recent ground movements at Columbia appear to be associated with landslide activity as outlined above. As a result of the movement, Columbia volunteered to suspend excavation from the north highwall. Investigation and analysis of the movement is recommended to confirm and evaluate the recent movement as well as potential impacts to ground stability in other potential quarry areas. The following bullets outline a phase approach to investigation and analysis. The work scopes of later phases are dependent in part on the results of earlier phases. Phase 1 – Surveying. Initial recommendations that have been previously discussed in person and email include: October 26, 2017 5 Cornforth Consultants, Inc. 2642  Temporary monitoring of the area of recent ground movement north of the quarry is being performed by Columbia personnel to measure ground surface movements over the short-term, or until a long-term monitoring system can be established. It is our understanding that a GPS system is being used to measure changes in positioning of temporary hubs (painted X’s on the ground surface). Frequency of monitoring has been daily since October 4, which will soon change to three times per week.  Long-term monitoring is recommended using permanent hubs that can survive the winter, such as lengths of rebar or similar embedded 3 feet. Consider extending them above anticipated snow levels. Three east-west survey monitoring lines have been recommended, approximately 100, 300 and 500 feet up slope to the north of the quarry’s northern highwall. The proposed survey lines should extend to a minimum distance of 150 feet east and west, outside of the disturbed ground area. Survey hubs should be set at approximate 100-foot intervals.  Monitoring of the northern quarry highwall, where the ground cracks occur up slope to the north, should also be performed for safety and working at the facilities. Highwall monitoring could be performed with different methods, such as a total station to survey mounted prisms as needed, or radar scanning or ground-based laser scanning to near continuously monitor and alarm for ground movement and rock fall. Phase 2 – Investigation, Analysis and Conceptual Options. Based on our preliminary assessment, the following are recommended to investigate and analyze the ground movement:  Long-term monitoring is also recommended within the quarry floor and to within 150 feet outside of the recently excavated area.  Produce high-resolution aerial imagery and use SfM (Structure from Motion) software to develop a 3-dimension, georeferenced model of the ground surface extending a minimum 100 feet outside of the property line, and 800 feet to the north. Tie the property lines and corners into the model. It appears the quarry’s existing Kespry drone system could be used to develop the 3D model. Alternatively, a subcontractor could be retained that specializes in unmanned aircraft systems (drones) to image the ground surface and develop 3D models.  Map ground cracks and fissures that are not visible in the 3D model using GPS methods, and manual measurement of dimensions and directions of displacements.  Review history of material excavation and production, including information on where production came from within the quarry, if available. DNRs aerial photography file could also be used in a review of operation history.  Acquire Washington DNRs LiDAR data (available from 2005, 2008 and 2015) and evaluate for changes in the ground surface conditions, such as materials moved within and out of the quarry operation.  Perform subsurface drill hole exploration and instrumentation to determine subsurface geometry and material properties. Sample subsurface materials and install geotechnical instrumentation to measure the base of ground deformation (slope inclinometer) and the October 26, 2017 6 Cornforth Consultants, Inc. 2642 groundwater pressures (piezometer) at that zone. Based on the results of our preliminary interpretation and available geologic information (maps, reports, and surface exposure), two to four exploratory borings (estimated 200 to 300 feet deep) are recommended up slope to the north and east of the quarry. I Map the geology of the quarry property, to check the 1993 geologic map, and to look for unmapped geologic faults and fracture zones. I Compile the above information into a 3-dimensional model of the projected subsurface conditions and landslide geometry. I Produce cross section models for landslide stability analysis and perform analysis for conditions at time of failure, which is assumed to be May 2017. I Perform iterative methods of landslide stability analysis to evaluate the relationship between material excavation, the occurrence of ground movement, and the potential ground stability prior to quarrying and at the available times of documented surface conditions. I From the results of analyzing recent ground movements, project material properties and subsurface conditions to develop models of subsurface and possible paleo-landslide conditions elsewhere within the quarry property. I Evaluate options to mitigate the recent ground movement. I Assess potential impacts to ground stability in other potential quarry areas, primarily to the east of the eastern highwall. I Meetings with Columbia to review the results as needed. I Provide a report summarizing the results of the above-outlined tasks. Phase 3 Design Mitigation, Design Future Stability Plan. The scope of this phase would be based on the results of Phase 2. We appreciate the opportunity to provide our technical services to Columbia.

This warranty is in lieu of all other warranties, either expressed or implied. The geotechnical report was prepared for the use of the Owner in the design of the subject facility and should be made available to potential contractors and/or the Contractor for information on factual data only. This report should not be used for contractual purposes as a warranty of interpreted subsurface conditions such as those indicated by the interpretive boring and test pit logs, cross-sections, or discussion of subsurface conditions contained herein. The analyses, conclusions and recommendations contained in the report are based on site conditions as they presently exist and assume that the exploratory borings, test pits, and/or probes are representative of the subsurface conditions of the site. If, during construction, subsurface conditions are found which are significantly different from those observed in the exploratory borings and test pits, or assumed to exist in the excavations, we should be advised at once so that we can review these conditions and reconsider our recommendations where necessary. If there is a substantial lapse of time between the submission of this report and the start of work at the site, or if conditions have changed due to natural causes or construction operations at or adjacent to the site, this report should be reviewed to determine the applicability of the conclusions and recommendations considering the changed conditions and time lapse. The Summary Boring Logs are our opinion of the subsurface conditions revealed by periodic sampling of the ground as the borings progressed. The soil descriptions and interfaces between strata are interpretive and actual changes may be gradual. The boring logs and related information depict subsurface conditions only at these specific locations and at the particular time designated on the logs. Soil conditions at other locations may differ from conditions occurring at these boring locations. Also, the passage of time may result in a change in the soil conditions at these boring locations. Groundwater levels often vary seasonally. Groundwater levels reported on the boring logs or in the body of the report are factual data only for the dates shown. Unanticipated soil conditions are commonly encountered on construction sites and cannot be fully anticipated by merely taking soil samples, borings or test pits. Such unexpected conditions frequently require that additional expenditures be made to attain a properly constructed project. It is recommended that the Owner consider providing a contingency fund to accommodate such potential extra costs.
