Historical "Tonnes Remaining" has been corrected to reflect up-to-date inventory information. BC Hydro's system plan anticipates the removal of all high level PCB (polychlorinated biphenyls) material from service by 2007. BC Transmission Corporation now accounts for all high-level PCBs formerly reported by BC Hydro.
