166. Every permanent lighting enclosure fitted in a cargo pump room shall be gas-tight and maintain the fire integrity of the bulkhead.

The electrical supply to the tachograph must be provided via a safety barrier connected directly to the battery (marginal 220 514) and the electrical equipment of the mechanism for lifting a bogie axle must be installed where it was originally installed by the vehicle manufacturer and must be protected in an appropriate sealed housing (marginal 220 517).

1. Displacement vapours from the mobile container being loaded must be returned through a vapour-tight connection line to a vapour recovery unit for regeneration at the terminal.

Vapours displaced by the delivery of petrol into storage installations at service stations and in fixed-roof tanks used for the intermediate storage of vapours must be returned through a vapour-tight connection line to the mobile container delivering the petrol.

Alberta's oil reserves are sourced in the following ways: by strip mining shallow bitumen sands deposits, where 90% recovery of original oil-in-place is achieved; by in situ extraction of bitumen sands in deeper deposits using cyclic steam stimulation, now achieving recovery factors of 35% to 40%; by steam-assisted gravity drainage, typically achieving recovery factors exceeding 50%, and sometimes up to 70%; by in situ extraction of bitumen carbonate deposits, where two successful commercial-scale pilot projects in the Grosmont deposit are now both proceeding to full scale-development; and by multiple fracking of horizontal wells in tight oil shales containing a large oil resource little developed as yet, but classed as “proved undev ...[+++]eloped”, based on success exploiting analogous tight oil shales in the U.S. These recent developments and improvements in recovery factors indicate Alberta's proved oil reserves are 848 billion barrels.
