From the May 7th, 2014 Times Colonist Newspaper in Victoria, BC:
Saanich homeowners will have to remove their old buried oil tanks once they are taken out of service under bylaw changes soon to be approved by the Saanich Council.
According to Coun. Dean Murdock: "Tanks are no longer (installed) underground, and that's not best practice. But in cases where they've been left underground, the regulatory change now requires that they be removed"
Saanich's current bylaw requires that old tanks no longer in service be made inert. The bylaw change will not apply to those where the work has been done.
