Description

This Standard sets forth the minimum requirements for containment sumps, and associated sump fittings and accessories (products) intended for below- or at-grade use as an enclosure for housing of, and access to, underground piping, connector piping, and other fueling system components (such as pumps, valves, sensors, wiring, etc.) in addition to temporary containment of typical liquid fuels as identified in this Standard. These products are intended for use in commercial (public) or private (fleet) automotive fueling station applications or similar fuel dispensing applications, and piping systems for fuel supply of generators, burners or similar equipment. Some sump fitting or sump accessory products may be optionally evaluated for repair or replacement applications in containment sumps that have been in service.

Containment sumps may be either primary or secondary constructions of metallic, nonmetallic or composite materials. Typical containment sump types are:
A   Tank sumps – Sumps intended for installation above underground flammable and combustible liquid storage tanks;
B   Dispenser sumps – Sumps intended for installation below flammable and combustible liquid dispensing equipment;
C   Transition sumps – Sumps intended for access to liquid or vapour piping run manifolds, fittings and valves in a fueling system;
and D   Fill/vent sumps – Sumps intended for housing of fill and/or vent pipe ends, drain valves, gauges or monitors connected to the tank.

Containment sumps, fittings and accessories are intended for containment of automotive fuels and exposure to soil fluids that have similar chemical, physical and material compatibility properties as represented by the test liquids in these requirements. Refer to Appendix B (Informative) List of Standards on Fuels, for a list of Standards on fuels and other liquids.

Products covered by this Standard are intended to be installed and used in accordance with, but not limited to, any of the following documents:
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.

These products are factory manufactured and intended for on-site field assembly, inspection and leak testing for the specified applications and use conditions by qualified persons in accordance with the manufacturer’s instructions and local requirements.

These products are intended to be periodically inspected and maintained for continued service, or taken out of service if necessary by qualified persons in accordance with industry recommended practices and/or the manufacturer’s instructions.

These products have not been evaluated for use after natural disasters, fires or exposures to chemicals not representative of the test liquids or excessive physical damage beyond the expected assembly, installation and uses as identified in these requirements.

These products have not been evaluated for special use applications where exposed to heavy or continuous physical abuses, excessive mechanical stresses; or environments that operate outside of the expected atmospheric conditions and ambient use temperature range.

These requirements do not cover underground piping products (refer to CAN/ULC-S660, Standard for Nonmetallic Underground Piping for Flammable and Combustible Liquids and CAN/ULC-S667, Standard for Metallic Underground Piping for Flammable and Combustible Liquids).

These requirements do not cover connector piping products (refer to CAN/ULC-S633, Standard for Flexible Underground Hose Connectors for Flammable and Combustible Liquids).
