Department The University of British Columbia 1956 Main Mall Vancouver, Canada V6T 1Y3 Date DE-6G/81) ABSTRACT Procedures for the selection, licensing and implementation of large scale energy projects must evolve with the escalating complexity of such projects and. the changing public value system. Government appeared unresponsive to rapidly changing conditions in the 1960s and 1970s. Consequently, approval of major hydroelectric development projects in British Columbia under the Water Act became increasingly more contentious. This led, in 1980, to the introduction of new procedures—the Energy Project Review Process (EPRP)— under the B.C. Utilities Commission Act. This study documents and evaluates the selection, licensing and implementation of the Revelstoke Hydroelectric Dam under the Water Act and assesses to what extent the current EPRP selection and licensing procedure overcame the shortcomings of the Revelstoke experience. The methodological approach used is that of a post-development analysis. The Revelstoke Project case study revealed that the Water Act only addressed project design, safety, and impacts, but not selection and justification. Project implementation proceeded under a conditional water licence. The two-part administrative framework, established under the licence and by B.C. Hydro, lacked integration and failed to provide effective management. A strong commitment to the preservation of environmental quality was lacking. The licensee's monitoring of construction practices in general and of compliance with environmental guidelines, a set of nonspecific commonly accepted construction activities, were inadequate. Governmental surveillance and enforcement were rendered unsatisfactory by staff shortages and a laissez faire attitude. The case study concluded with a post-development environmental analysis, which determined the effectiveness of the Environmental Impact Statement in predicting impacts to be only twenty-five percent. Evaluation of the EPRP and its application in the Site C Dam proposal demonstrated that it is a significant improvement over its predecessor. If applied efficiently and in its entirety, it would provide an adequate structure and procedural sequence for project selection and licensing. However, some of the inadequacies noted in the Revelstoke case study, such the lack of provisions for early public and government participation, an adequate data base, an administrative structure, and a post-development analysis, have not been or only partially corrected. To conclude, this thesis offers some recommendations to further improve this continually evolving process. iv TABLE OF CONTENTS ABSTRACT ii TABLE OF CONTENTS iv LIST OF TABLES vi LIST OF FIGURES vii ACKNOWLEDGMENTS viii GLOSSARY ix CHAPTER 1.

At nearly 10 km2 in area, 250 m deep and approximately 1.5 billion m3 in volume, this is the world’s largest known landslide stabilization project. Construction of the Revelstoke Dam was contingent on the stabilization of Downie Slide. Key safety issues were the potential for reservoir blockage, a landslide-generated wave, and upstream flooding of Mica Dam, approximately 70 km to the north.

  • Columbia Basin White Sturgeon Planning Framework
    Review Draft Review Draft Columbia Basin White Sturgeon Planning Framework Prepared for The Northwest Power & Conservation Council February 2013 Review Draft PREFACE This document was prepared at the direction of the Northwest Power and Conservation Council to address comments by the Independent Scientific Review Panel (ISRP) in their 2010 review of Bonneville Power Administration research, monitoring, and evaluation projects regarding sturgeon in the lower Columbia River. The ISRP provided a favorable review of specific sturgeon projects but noted that an effective basin-wide management plan for white sturgeon is lacking and is the most important need for planning future research and restoration. The Council recommended that a comprehensive sturgeon management plan be developed through a collaborative effort involving currently funded projects. Hatchery planning projects by the Columbia River Inter-Tribal Fish Commission (2007-155-00) and the Yakama Nation (2008-455-00) were specifically tasked with leading or assisting with the comprehensive management plan. The lower Columbia sturgeon monitoring and mitigation project (1986-050-00) sponsored by the Oregon and Washington Departments of Fish and Wildlife and the Inter-Tribal Fish Commission also agreed to collaborate on this effort and work with the Council on the plan. The Council directed that scope of the planning area include from the mouth of the Columbia upstream to Priest Rapids on the mainstem and up to Lower Granite Dam on the Snake River. The plan was also to include summary information for sturgeon areas above Priest Rapids and Lower Granite. A planning group was convened of representatives of the designated projects. Development also involved collaboration with representatives of other agencies and tribes involved in related sturgeon projects throughout the region.

At 2,000 kilometres long, the Columbia River is the fourth largest river in North America. The headwaters of the Columbia River are in Canal Flats, British Columbia (B.C.). The river then flows northwest Canada through the Rocky Mountain trench before heading south through B.C. and Washington, emptying into the Pacific Vancouver Ocean at Astoria, Oregon. Other major tributaries of the Columbia River in Canada include the Kootenay and Pend U.S. d’Oreille rivers. Seattle Only 15% of the Columbia River basin lies in Canada. The Montana Canadian portion of the basin is mountainous and receives a Washington lot of snow producing, on average, 30 to 35% of the runoff for Canada and the United States (U.S.) combined. The river’s large annual discharge and relatively steep gradient Idaho gives it tremendous potential for the generation of Oregon electricity. The hydroelectric dams on the Columbia’s main stem and many more on its tributaries produce more hydroelectric power than on any other North American river. BC Hydro’s facilities in the Columbia basin include 13 hydroelectric dams, two water storage dams, and a system of reservoirs.

The application was submitted to the Comptroller of Water Rights (CWR) as required by the BC Water Sustainability Act. Water Licence Application As you may be aware, BC Hydro is currently pursuing regulatory approvals for the addition of a sixth generating unit at Revelstoke Dam and Generating Station (Revelstoke 6 Project). On February 28,2017, we submitted an application for an Environmental Assessment Certificate with the provincial EnvironmentalAssessment Office who will conduct an environmental review. We submitted an application for a new licence in mid-March 2017. The water licence application and the environmental review will be conducted concurrently. The second water licence will allow us to operate the Generating Station at maximum power generating capacity when the sixth unit is installed. Although the Generating Station was licenced for six units when it was built in the 1980s, the newer generating units are more efficient than the original four, and can accommodate higher water flows. Discharge flows at maximum generation with six generating units would be 93,000 cubic feet per second (cfs). Our existing water licence allows us to use 90,000 cfs; the second licence would allow us to use an additional 3,000 cfs of water.
