2 March 9, 26 WSP File No: (LCL File # R ) CH2M Hill Metrotower II, Suite Kingsway Avenue Burnaby, BC V5H 4N2 Attention: Subject: Mr. Mark Clarke, P.Eng. Trans Mountain Expansion Project (TMEP) Enhanced FEED Study eotechnical Foreshore Investigation #2 (Marine Component) Findings Report Westridge Loading Facility, Burnaby, BC. INTRODUCTION & PROJECT DESCRIPTION This letter is the (WSP) findings report that contains the results of the recent geotechnical marine investigation undertaken along the foreshore area at the Kinder Morgan Westridge facility as part of the TMEP Enhanced FEED study. The TMEP development at Westridge will involve the construction of new infrastructure to expand the shiploading capabilities of the facility. We understand that the design for the facility expansion is still evolving, but will include new ship berthing facilities and loading infrastructure on the marine-side, and new piping, manifolds, processing equipment, and some small new storage tanks on the landside of the project. WSP has recently completed a geotechnical marine investigation programme for the foreshore portion of the project, which was completed as a component of a larger marine investigation being managed by older (also for Kinder Morgan). The WSP marine investigation was completed along the water side of the foreshore to obtain important information regarding soil stratigraphy of the submarine slopes adjacent to the north side of the foreshore. A summary of the WSP geotechnical marine investigation is presented in this findings report, which includes the detailed soil logs and laboratory test results from the investigation. The WSP geotechnical marine investigation programme included two types of geotechnical test holes: sonic drill holes completed to obtain information regarding soil stratigraphy as well as collect continuous soil samples throughout the zone of interest, and seismic cone penetration tests (SCPTs) to obtain information (where possible) in potentially liquefiable soil deposits. The test holes were completed at eight (8) locations arranged as two lines of four locations, approximately parallel to Clarke Place Richmond, BC V6V 2H9 Phone: Fax:

3 the foreshore. The sonic test holes were completed first, followed by the SCPTs offset slightly from the sonic hole locations (in order to avoid disturbance effects). In zones where overly dense soils were encountered during the SCPT tests, drillout with the sonic drill was undertake. The locations of the sonic and SCPTs are as shown on the attached Drawing. The sonic drill holes were completed using a truck-mounted sonic drill rig (owned and operated by Mud Bay Drilling Company Ltd.) carried by a barge (owned and operated by Van Pile) to the various locations. The approximately 2 mm diameter holes were advanced to depths of between 4.3 and 28.2 m below the seabed surface, depending on location and conditions encountered. Soil samples were collected from the continuous return of the drill. The seismic electronic cone penetration tests (SCPTs) were completed using equipment supplied and operated by ConeTec (and mounted on the Mud Bay drill rig), at locations and depths where the soils were judged to be of appropriate type and density to allow advancement of the cone, in order to assess the liquefaction potential of those soils. Where zones of overly dense soils or obstructive materials were encountered (e.g. cobbles, dense soils, etc.), drillout with the Mud Bay sonic rig was completed. Following completion of the sonic drilling and cone penetration testing, the holes were fully grouted, and the collected samples were returned to the WSP soils and materials laboratory in Richmond for further classification and testing. The locations of the sonic drill holes and the SCPTs are as shown on Drawing. 2. RESULTS OF EOTECHNICAL MARINE INVESTIATION (WINTER, 25) The information for the sonic drill holes and the SCPTs should be read together, as the information obtained from one method complements the other at any given location. In general, the SCPTs were completed where soil nature and density permitted; as noted, however, drill-out with the sonic drill was required at some locations and depths. Therefore, gaps appear in the SCPT logs at such locations. 2. SONIC DRILLIN The results of the sonic drill holes completed during this current phase of the project are shown on the attached test hole logs SH- through SH-8. Note that some gaps are shown on the logs (indicated as no recovery ); in these zones, the materials within the drilling casing were too loose/disturbed to facilitate sample recovery (generally at the seabed surface).

4 2.2 SEISMIC CONE PENETRATION TESTS (SCPTS) The results of the SCPTs are shown on the attached cone plots and pore pressure dissipation test summary. Note that the electronic cone tests capture a wide variety of information, and therefore, several plots are required for each test location/depth, in order to present all of the findings. An overview description of the plots for this investigation is as follows: For each test location and depth, ConeTec provided three plots: o o o A standard CPT plot that includes: corrected tip resistance (qt), sleeve friction (fs), friction ratio (Rf), and pore pressure (u); An advanced plot that includes an interpreted value for undrained shear strength (Su), based on published correlations; and A seismic plot that includes values for shear wave velocity (Vs) through the soils at various depths. ConeTec encountered some difficulties during the completion of the SCPTs, during which some loss of the test wave at each location led to incomplete measured shear wave velocity (Vs) data. ConeTec subsequently analyzed the data that was available and prepared an estimated Vs profile, based on empirical correlations developed by Dr. Peter Robertson, a leading expert for the development of electronic cone penetration testing. These estimated Vs profiles are shown as Est Vs on the attached seismic cone plots. Pore pressure dissipation tests were also completed at select locations and depths. The results of the tests are provided on the attached dissipation curves. 2.3 LABORATORY TESTIN Laboratory testing was completed on select soil samples obtained from the sonic drilling, in order to obtain additional information regarding basic soil characteristics. The tests completed include mechanical grain size analysis (sieves), hydrometer tests, and Atterberg Limits tests. A summary of the samples selected for testing, and the testing results, are attached. 3.

The phreatic surface was determined using pore pressure dissipations. Hydrostatic conditions were used for the interpretation tables. 2. Mudline depth from the water surface at the start of test. 3. The penetration depths are referenced to the existing mudline at the time of testing. 4. Coordinate were surveyed using RTK as-built survey and were collected in NAD83 UTM Zone North. 5. Elevations are referenced to the existing mudline at the time of testing. 6. Sounding terminated as cone is believed to have entered an earlier bore hole, no digital data presented. 7. Due to shallow test depths and large horizontal offsets, no interpretations were possible with the collected seismic data using the interval travel time method. 8. Average Vs estimated using the first break shear wave arrival at the final seismic depth in the profile. (m) Refer to Notation Number Sheet of
