Rio Tinto Alcan (RTA)
Kemano-Kitimat Power Line
Tower 113R and Catenary 2 construction
The RTA Tower 113R was destroyed by a Size 4.5 avalanche in March 2007.
The CSA Ltd. project was to plan, implement and operate an active avalanche program to minimize avalanche hazard at several worksites for the 2007 Tower 113 and "Catenary 1" repair project and the 2008-09 "Catenary 2" construction project. NWAS owner/Senior Avalanche Technician Rod Gee managed the avalanche program's field operations and was Senior on-site Forecaster/Technician.
Power Line Snow Instability and Avalanche Occurrence Observations
NWAS conducts regular snowpack and avalanche occurrence observations along the 80 km. power line corridor and around other power generation facilities. The observations are used to assist in long-term maintenance and planning, and to assist in initiating any required emergency repair projects.
Avalanche Safety Plan
NWAS assisted Chris Stethem and Associates Ltd. in 2009-10 to develop Rio Tinto Alcan's Avalanche Safety Plan in order to meet the requirements of WorkSafe BC's Occupational Health and Safety Regulation 4.1.1, Snow Avalanche Assessment. ASP implementation includes ongoing worker safety training, worksite risk assessment, explosives control and incident response integration into RTA’s emergency response systems.
