Site C Clean Energy Project Technical Briefing: Press Gallery June 7, 2017


Topics • Summary of key questions • Highway 29 realignment at Cache Creek • River diversion • Cost of delaying Cache Creek activities • Additional 2017 activities and procurements • Construction and project status

• Impacts of project cancellation

2


Summary of key questions • What is the impact of granting a further extension on the timeline so that impacted families can stay in their homes, in the current location, until the future of Site C is firmly determined? • Would upcoming procurement contracts contain penalty-free cancellation clauses? • What is the impact of going “tools down” on decisions that are essential to maintaining the budget and construction schedule? (e.g. for 3 months)

Discussions on relocation of homes • In 2016, BC Hydro acquired land and rights from eight property owners in the Cache Creek/Bear Flat area, including the Boons and Meeks.

• We have worked with all the affected property owners to minimize impacts as much as possible. • Short-term delays to issuing tenders for highway realignment and bridge construction enabled the extension of our lease agreement with Mr. and Mrs. Boon, from May 31 to end of June. • The Boons have indicated they intend to move into a vacant guesthouse on their property. We have offered to move their current home to a new location.

• Through our discussions with the Meeks, who are leasing their home to tenants, we came to agreement to move the house. 6


Highway realignment and river diversion • Starting in September 2019, the Peace River will be diverted through tunnels at the dam site, which may cause flooding in the Cache Creek/Bear Flat area. • To ensure highway realignment at Cache Creek/Bear Flat can be completed in time for river diversion in 2019, construction must start in summer 2017. • Diverting the river before completing highway realignment is not possible due to significant public safety risks. • River diversion must occur in September 2019 when the river is at its lowest point. • As a result, if the highway realignment is not started by this September, a yearlong delay would occur as river diversion would be delayed until September 2020. 7
