Comment: K.Jeff, yet almost every paved road in BC contains this 'Toxic Sludge' as the primary binding agent. During every rain event, trace amounts of this 'Toxic Sludge' leach out of the pavement into the surrounding countryside or street drains.

Perhaps you should be more concerned/alarmed about all the asphalt roads in BC, than a safe oil pipeline !
Non-toxic
