ULC 652

This Standard sets forth the minimum requirements for the adaptation of tanks or tank assemblies for the collection, storage and removal of used oil.
The stationary installation and use of used oil tank assemblies, may be covered by the requirements of the authority having jurisdiction and may include by reference, but not limited to the following:
A National Fire Code of Canada, Part 4;
B CSA B139, Installation code for oil-burning equipment; and
C CCME PN 1326, Environmental Code of Practice for Aboveground and Underground Storage Tank Systems Containing Petroleum and Allied Petroleum Products.
Standards for the tanks or tank assemblies covered by this Standard are identified in Section 4, Construction. As a result of revisions to those Standards published in 2019, in addition to traditional safety requirements for tanks that primarily evaluate functional operation, structural integrity, and mitigate fire & environmental hazards from loss of liquid containment under expected normal conditions; optional construction and/or performance requirements, and associated ratings, intended to address more severe conditions associated with the effects of Climate Change are now specified in an optional Climate Change Adaptation Appendix in each of those Standards.
