Storage Tank Systems for Petroleum Products and Allied Petroleum Products Regulations

Version of section 1 from 2012-05-04 to 2017-06-01:

 The following definitions apply in these Regulations.

aboveground tank

aboveground tank means a tank that operates at atmospheric pressure and that has all of its volume either above grade or encased within an unfilled secondary containment. (réservoir hors sol)

allied petroleum product

allied petroleum product means a product set out in Schedule 1. (produit apparenté)

CCME Code of Practice

CCME Code of Practice means the Environmental Code of Practice for Aboveground and Underground Storage Tank Systems Containing Petroleum and Allied Petroleum Products published by the Canadian Council of Ministers of the Environment in 2003. (Code de recommandations techniques du CCME)

certification mark

certification mark means the mark, such as a tag, label, plate or embossing, on or affixed to a tank or a component of a storage tank system, certifying that the tank or component conforms to the standards of a certification organization accredited by the Standards Council of Canada or conforms to the standards of the American Petroleum Institute or of the ASTM International. (marque de certification)

corrosion expert

corrosion expert means a professional engineer experienced in corrosion protection or a person recognized by NACE International as a corrosion specialist. (expert en corrosion)

free oil

free oil means the non-soluble, non-emulsified petroleum product or allied petroleum product layer that accumulates in an oil-water separator. (huile libre)


Minister[Repealed, SOR/2012-99, s. 20]

partially buried tank

partially buried tank means a tank that has part of its volume above grade and part of its volume below grade, unless all of the tank volume is encased within an unfilled secondary containment. (réservoir partiellement enfoui)

petroleum product

petroleum product means, other than an allied petroleum product, a single hydrocarbon or a mixture of at least 70% hydrocarbons by volume, refined from crude oil, with or without additives, that is used or could be used as a fuel, lubricant or power transmitter, and includes used oil, but does not include propane, paint and solvents. (produit pétrolier)


piping means pipes and tubing, including fittings and valves, that are for the handling and storage of petroleum products and allied petroleum products. (raccordement)

secondary containment

secondary containment means containment that prevents liquids that leak from a storage tank system from reaching outside the containment area and includes double-walled tanks, piping, liners and impermeable barriers. (confinement secondaire)

separated solids

separated solids means the particulate material that settles at the bottom of an oil-water separator. (solide séparé)


spill means any loss of a petroleum product or an allied petroleum product in liquid form from a storage tank system, including a loss during a transfer of such a product to or from a storage tank system, but not including a loss that does not reach outside the storage tank system’s secondary containment. (déversement)

storage tank system

storage tank system means a tank or commonly connected tanks and all piping, vents, pumps, sumps, diking, overfill protection devices, spill containment devices and oil-water separators. In the case of a system located at an airport, the system ends at the pump discharge. (système de stockage)


tank means a closed container with a capacity of more than 230 L that is designed to be installed in a fixed location. (réservoir)

transfer area

transfer area means the area around the connection point between a delivery truck, railcar, aircraft or vessel and a storage tank system in which the tanks have an aggregate capacity of more than 2 500 L. (aire de transfert)

underground tank

underground tank means a tank that operates at atmospheric pressure and that has all of its storage volume below grade and completely surrounded by fill. (réservoir souterrain)

used oil

used oil means oil — other than oils derived from animal or vegetable fats, other than crude oil or recovered fuel oils spilled onto land or into water and other than wastes from petroleum refining operations — that has become unsuitable for its original purpose due to the presence of impurities or the loss of original properties, including

  • (a) lubricating oil for use in engines, turbines, or gears;

  • (b) hydraulic fluid, including transmission fluid; and

  • (c) insulating oil. (huile usée)
