<strong>BC</strong> <strong>Hydro</strong> continually reviews the security and reliability of<br />
our electrical system. A number of investigations and upgrades<br />
were undertaken in 2000, particularly for earthquake impacts.<br />
Work included reinforcing foundations for several transmission<br />
towers along the Fraser River in Richmond and Delta, and<br />
anchoring equipment at numerous substations throughout<br />
the province. We also reinforced the towers supporting two<br />
transmission lines to Vancouver Island to better withstand<br />
high snow loads on steep terrain, and upgraded the earthquake<br />
resistance of a number of buildings at Ingledow, Dunsmuir,<br />
Cheekye and Murrin No. 1 substations.<br />
We plan for response and recovery from disastrous events in<br />
order to improve public safety and more quickly restore service<br />
following damage to our system. Two exercises were undertaken<br />
in 2000 to test procedures for responses to disasters, and to<br />
train staff in appropriate actions. The first was the simulated<br />
release of excessively high flows from Seven Mile Dam, and<br />

involved interactions among <strong>BC</strong> <strong>Hydro</strong>, the community and<br />
government agencies in the Columbia River Valley. The second<br />
involved simulated response and recovery actions resulting from<br />
a major ice storm affecting the western end of the Fraser Valley.<br />
We also developed the Cheakamus River Valley Flood<br />
Communications Plan in 2000 in consultation with area residents<br />
and emergency response professionals. The plan provides for warning<br />
in the event of flooding downstream of the Daisy Lake Dam, located<br />
north of Squamish and Brackendale. The plan’s three-step alert<br />
system to notify residents was tested in an exercise late last year.<br />
Two seminars were held to train staff to evaluate safety in<br />
buildings immediately following an earthquake. The event drew<br />
about 50 <strong>BC</strong> <strong>Hydro</strong> staff and 25 people from other organizations.
