2 AECOM 3292 Production Way, Floor tel Burnaby, BC, Canada V5A 4R fax May 17, 2017 British Columbia Railway Company West Esplanade North Vancouver BC V7M 3J3 richard.myhilljones@gov.bc.ca Attention: Richard K. Myhill-Jones Director, Real Estate CN Acquisition Limited Avenue 2 Floor, Building B Edmonton, AB, T5E 0B9 Attention: Sara Lovegrove CN Design and Construction/Prairie Utilities Coordinator Dear Sirs and Mesdames: Regarding: North Shore Wastewater Treatment Plant - Conveyance System Utility Crossing Application We write with respect to the following railway line lands which are owned by the British Columbia Railway Company ( BCR ) and leased to CN Acquisition Limited ( CN ): PID: Legal Description: DISTRICT LOT 4286 (REFERENCE PLAN 1270) GROUP 1 NEW WESTMINSTER DISTRICT, EXCEPT PART IN REFERENCE PLAN 3863 (the Railway Line ). The Greater Vancouver Sewage and Drainage District ( GVS&DD ) is undertaking a secondary treatment upgrade program on the North Shore of Burrard Inlet, which is required by Metro Vancouver's Integrated Liquid Waste and Resource Management Plan (ILWRMP), as approved pursuant to the Environmental Management Act, and the new federal Wastewater Systems Effluent Regulations ( WSER ). The North Shore Wastewater Treatment Plant (NSWWTP) is being constructed within the District of North Vancouver and will replace the existing Lions Gate Wastewater Treatment Plant (LGWWTP), which is located within the District of West Vancouver and which was commissioned in The LGWWTP provides primary waste water treatment to the 200,000 residents of the North Shore municipalities of West Vancouver, the City of North Vancouver and 2017 AECOM Canada Ltd.

The NSWWTP Program comprises design and construction of the new secondary wastewater treatment plant, design and construction of interconnection works between the LGWWTP and the NSWWTP (the conveyance system ), and decommissioning of the existing LGWWTP. The NSWWTP must be operational by the end of 2020 per the ILWRMP and the WSER. The conveyance system to and from the NSWWTP includes the following: a wastewater pump station a new 900mm diameter forcemain extending from the new pump station to the NSWWTP (the forcemain ), a 2100 mm secondary effluent pipe extending from a chamber upstream of the marine outfall at LGWWTP to the NSWWTP (the effluent pipe ), a 1200mm diameter extension of the trunk sewer system from the LGWWTP to the new pump station, and various other sewer connections and trunk sewer extensions to facilitate the conveyance of wastewater from the District of North Vancouver and the Squamish Nation to the NSWWTP The proposed alignment of the forcemain and effluent pipe ( Utility Line ) extends east from the LGWWTP generally parallel to and north of the existing Canadian National Railway ( CNR ) tracks within the Railway Line. The Utility Line will cross beneath the CNR tracks under the Lions Gate Bridge. We propose constructing the Utility Line at Mile MP 1.90 of the Railway Line, Squamish Subdivision which is within District of West Vancouver boundary, on the east side of the Bridge Road and the existing LGWWTP and approximately 16.2m east of the Lions Gate Bridge piers. According to the proposed design, both the Utility Line will be encased in steel casings and installed by trenchless techniques. GVS&DD plans to procure the conveyance system work through a Design-Build methodology. GVS&DD will engage in a competitive selection process in order to retain a single entity ( Project Co ) to design, build and commission the work. To meet GVS&DD deadline to achieve secondary effluent treatment of December 31, 2020, the Design-Build approach is necessary to meet the schedule constraints of the project.

We have addressed this package to both BCR and CN because we understand that under the terms of its lease, CN cannot offer GVSDD any rights to occupy or use the Railway Line for underground work. During the Design Build phase either the Project Co or GVS&DD will provide detailed design plans for the utility crossings. Please do not hesitate to contact me ( ) if you have any questions or concerns. Sincerely, AECOM Canada Ltd. Tatiana Irimia, P.Eng.
