ULC 676 – Standard for Refurbishing of Storage Tanks for Flammable and Combustible Liquids

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

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.

The installation and use of refurbished tanks may be covered by the requirements of the Authority Having Jurisdiction.

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

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.

These requirements apply to all repair activities of storage tanks and integral appurtenances designed to contain flammable liquids or combustible liquids, under atmospheric pressure.
