This Standard covers the minimum requirements for nonmetallic or composite primary tanks@ secondary tanks@ and open or closed secondary containments from 227 to 2500 L (60 to 660 US gal) primary tank capacity intended primarily for the storage and supply of heating fuel for oil burning equipment@ or alternately for the storage of diesel fuels for compression ignition engines and motor oils (new and used) for automotive service stations@ in aboveground applications. Each tank type is permitted to be fabricated in a combination of various shapes (cylindrical@ rectangular or obround)@ orientations (horizontal@ vertical) and may have integral options (tank supports or accessories) as covered in this Standard. These shop built tanks are completely fabricated@ inspected@ and tested for leakage before shipment from the factory as completely assembled vessels except for options intended for field assembly in accordance with the manufacturer??s instructions. These tanks are intended for stationary installation and use in accordance with@ but not limited to@ any of the following documents as appropriate for each country below. These tanks are not intended for the transportation of fuel@ nor are they intended to be transported while containing liquids. A For the United States; ANSI/NFPA 31@ Standard for the Installation of Oil-Burning Equipment; ANSI/NFPA 30@ Flammable and Combustible Liquids Code; NFPA 30A@ Code for Fuel Dispensing Facilities and Repair Garages; and the International Fire Code published by the International Code Council. B For Canada; the National Fire Code of Canada; CSA B139@ Installation Code for Oil Burning Equipment; Regulations of the appropriate authority having jurisdiction; and CCME Environmental Code of Practice for Aboveground and Underground Storage Tank System Containing Petroleum and Allied Petroleum Products. These requirements do not apply to steel tanks covered by the following standards: A UL 80@ Standard for Steel Tanks for Oil-Burner Fuels; B CAN/ULC-S602@ Standard for Aboveground Steel Tanks for Fuel Oil and Lubricating Oil; C UL 142@ Standard for Steel Aboveground Tanks for Flammable and Combustible Liquids; D CAN/ULC-S601@ Standard for Shop Fabricated Steel Aboveground Tanks for Flammable and Combustible Liquids; E UL 58@ Standard for Steel Underground Tanks for Flammable and Combustible Liquids; or F CAN/ULC-S603@ Standard for Steel Underground Tanks for Flammable and Combustible Liquids. These requirements do not apply to nonmetallic tanks covered by the following standards: A UL 1316@ Standard for Glass-Fiber-Reinforced Plastic Underground Storage Tanks for Petroleum Products@ Alcohols@ and Alcohol-Gasoline Mixtures@ and CAN/ULC S615@ Standard for Fibre Reinforced Plastic Underground Tanks for Flammable and Combustible Liquid; or B UL 1746@ Standard for External Corrosion Protection Systems for Steel Underground Storage Tanks@ and CAN/ULC-S603.1@ Standard for External Corrosion Protection Systems for Steel Underground Tanks for Flammable and Combustible Liquids. These requirements do not cover storage of waste oils or other combustible liquids with different fire@ physical or material compatibility properties with respect to the intended liquids in Clause 1.1 but do cover 100 % biodiesel and biodiesel blends up to 100 %. These requirements do not cover storage of flammable liquids. These requirements do not cover special evaluations for resistance to hurricanes@ tornadoes@ earthquakes@ floods@ fires or other natural disasters; or resistance to vehicle impact.
