1 SCOPE

1.1 This Standard covers the refurbishing of shop fabricated tanks built to nationally recognized

Standards listed in Tank Eligibility Subsections 6.2 and 7.2.

NOTE: In the context of this Standard, refurbishing refers to repairs to, and a limited set of modifications of, tanks

using materials at least equivalent to those used in the original manufacture and does not include retrofit. Refer to

Standard CAN/ULC-S669, Standard for Internal Retrofit Systems for Underground Tanks for Flammable and

Combustible Liquids, for requirements applicable to retrofit activities.

1.2 This Standard provides minimum requirements for the inspection, evaluation and refurbishing of steel

and fibre reinforced plastic underground and aboveground storage tanks for flammable liquids and

combustible liquids. This Standard addresses the refurbishing of tanks in a refurbishing company’s facility

in Part II, the refurbishing of tanks at their installed location in Part III, and also provides inspection criteria

for the frequent relocation of aboveground tanks in Part IV.

NOTE: Refer to Appendix A for examples of flowcharts applicable to refurbishing.

1.3 The installation and use of refurbished tanks may be covered by the requirements of the Authority

Having Jurisdiction and may include by reference, but are not limited to:

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.

1.4 The transport of tanks to a refurbishing facility is not within the Scope of this Standard.

NOTE: Authorities Having Jurisdiction may have requirements for the cleaning and preparation of tanks for removal

from service, prior to transport to the refurbishing facility.

1.5 This Standard is intended for use by organizations and/or individuals who are knowledgeable and

experienced in underground tank or aboveground tank fabrication, repair, modification and inspection.

NOTE: Refer to Personnel Qualifications Subsections 6.1 or 7.1, as applicable.

1.6 These requirements apply to all repair activities of storage tanks and integral appurtenances designed

to contain flammable liquids or combustible liquids, under atmospheric pressure.

Project need:

Project Need
There are two revisions to S676; 1. First revision proposal adds Clauses to this standard to allow the replacement of a tank nameplate that may be damaged, inaccurate, or illegible for a number of reasons, including error(s) or omission(s) during the creation of the nameplate, or damage/deterioration during transport, installation or use, without imposing the inspection and testing requirements applicable after repairs or modifications. 2. Second revision proposal address the Certification Mark; If the original Certification Mark remains on the tank after refurbishing, it has and will continue to be mistakenly interpreted by the owner/operator and AHJ, that the tank is still Certified and also meets the requirements of a Standard different than CAN/ULC-S676. Both of these interpretations are false. Furthermore, the inconsistent modifications permitted under Subsections 4.3, Applicable Tank Standard or ORD, and 4.5, Modifications, without the oversight of the original third-party certifier, could lead to safety risks, such as potential leakage, reduced mechanical strength and structural failure.
