PART IIIStorage Tanks

 A cylinder or tank with a water capacity not exceeding 100 Imperial gallons and manufactured, filled, operated and maintained in accordance with a Canadian Transport Commission or an Interstate Commerce Commission specification, which is approved by either of these authorities for liquefied petroleum gas, is exempt from the provisions of this Part, except sections 23, 27 and 32.

  •  (1) The water capacity of any storage tank located on carrier’s right-of-way and used for liquefied petroleum gas shall not exceed 25,000 Imperial gallons.

  • (2) The aggregate water capacity of tanks assembled in a group shall not exceed 150,000 Imperial gallons.  Groups of tanks shall be segregated as prescribed in subsection 18(16).

  •  (1) Except as provided in subsection (7), storage tanks shall be securely installed on solid foundations of steel or concrete with reinforced concrete footings extending below the frost line, or resting on bedrock.

  • (2) Except as provided in subsection (6), steel foundations shall be fireproofed with a material having a fire resistance of not less than 2 hours.

  • (3) Foundations shall be of sufficient width and thickness to adequately support the tank and its contents.

  • (4) Provision shall be made for the thermal expansion and contraction of a tank.

  • (5) Only two saddles shall be used on horizontal tanks.

  • (6) Steel saddles, which are welded to a tank, need not be fireproofed if the tank capacity does not exceed 500 Imperial gallons or if the over-all height of the saddle does not exceed 18 inches.

  • (7) Footings for tanks with a water capacity less than 500 Imperial gallons need not be installed below frost line if adequate provision is made to protect the piping against the effects of setting.

  •  (1) Storage tanks shall be constructed in accordance with the 1956, 1959 or 1962 issue of the A.S.M.E. Boiler and Pressure Vessel Code for Unfired Pressure Vessels to a design working pressure not less than 125 per cent of the vapour pressure of the liquefied petroleum gas at 100°F, but not less than 250 psig for liquefied propane.  The factor of safety shall not be less than 4.

  • (2) The tank design drawings and specifications shall be approved by the Pressure Vessel Inspection Branch of the provincial government concerned prior to fabrication of the tank.

  • (3) Tank design drawings and specifications shall be in accordance with the requirements of Canadian Standards Association Pamphlet B-51.
