Section 580.5 - Bulk Gasoline Plants

580.51 Section 580.5 shall apply to all gasoline bulk plants.

580.511 It shall be unlawful for any person to cause or allow the storage of gasoline in tanks with a capacity of two thousand one hundred liters (550 gallons) or greater unless such storage is in tanks meeting the following conditions:

580.5111 Each storage tank shall be equipped with a submerged fill line.

580.512 It shall be unlawful for any person to cause or allow transfer of gasoline between a storage tank and a transport tank except under the following condition:

580.5121 All transport tanks shall be submerged filled or bottom loaded.

580.52 Section 580.52 shall apply to all bulk gasoline plants with an annual gasoline throughput greater than seven million six hundred thousand liters (2,000,000 gallons).

580.521 It shall be unlawful for any person to cause or allow the storage of gasoline in tanks with a capacity of two thousand one hundred liters (550 gallons) or greater unless such storage is in tanks meeting the following conditions.

580.5211 Each storage tank shall be equipped for vapor balancing of gasoline vapors with transport tanks during gasoline transfer operations.

580.5212 The vapor line fittings on the storage tank side of break points with the transport tank vapor connection pipe or hose shall be equipped to close automatically upon planned or unintentional disconnect.

580.5213 The pressure relief valves on storage tanks shall be set at the highest possible pressure consistent with local and state codes for fire and safety.

580.522 Except as provided in 580.523 of this section, it shall be unlawful for any person to cause or allow the transfer of gasoline into or out of any transport tank at a bulk gasoline plant unless said transfer is in compliance with the following conditions:

580.5221 The transport tank shall be equipped with the proper attachment fittings to make vapor-tight connections for vapor balancing with storage tanks; and

580.5222 The vapor line fittings on the transport tank side of break points with the storage tank connection pipe or hose shall be equipped to close automatically upon planned or unintentional disconnect; and

580.5223 The pressure relief valves on transport tanks shall be set at the highest possible pressure consistent with local and state codes for fire and safety.

580.523 The vapor line fittings on the storage tank side of break points with the transport tank vapor connection pipe or hose shall be equipped to close automatically upon planned or unintentional disconnect.

580.5231 The transport tank is used exclusively for the delivery of gasoline into storage tanks of a facility exempt from the vapor balance requirements of 580.6; and

580.5232 The transport tank has a total capacity less than fifteen thousand liters (4,000 gallons) and is of a compartmented design and construction requiring the installation of four or more separate vapor balance fittings.

580.524 The pressure relief valves on storage tanks shall be set at the highest possible pressure consistent with local and state codes for fire and safety.

580.5241 The loading of all transport tanks, exempted under 580.523 of this section, shall be performed such that at least ninety percent by weight of the gasoline vapors displaced during filling are prevented from being released into the ambient air; providing that emissions from pressure relief valves shall not be included in the controlled emissions. This emission limitation will be met by vapor balancing in compliance with all provisions of this section.

580.525 It shall be unlawful for any person to cause or allow continued transfer of gasoline at any transfer point following occurrence of failure or leakage in any part of the vapor balance system, provided that occurrence of failure or leakage during loading or unloading of a transport tank shall not prevent the complete loading or unloading of the tank.

580.526 It shall be unlawful for any person to cause or permit the operation of a bulk gasoline plant or a transport tank without taking reasonable necessary measures to prevent the spilling, discarding in sewers, storing in open containers or handling of gasoline in a manner on the plant site that will result in evaporation to the ambient air.

580.53 Except as provided in 580.54 of this section, it shall be unlawful for any person to cause or allow the transfer of gasoline into or out of any transport tank at a bulk gasoline plant unless said transfer is in compliance with the following conditions:

580.531 The transport tank shall be equipped with the proper attachment fittings to make vapor-tight connections for vapor balancing with storage tanks; and

580.532 The vapor line fittings on the transport tank side of break points with the storage tank connection pipe or hose shall be equipped to close automatically upon planned or unintentional disconnect; and

580.533 The pressure relief valves on transport tanks shall be set at the highest possible pressure consistent with local and state codes for fire and safety.

580.54 Transport tanks used for gasoline shall be exempt from the requirement to be equipped with any attachment fitting for vapor balance lines, provided the following conditions are met:

580.541 The transport tank is used exclusively for the delivery of gasoline into storage tanks of a facility exempt from the vapor balance requirements of 580.6; and

580.542 The transport tank has a total capacity less than fifteen thousand liters (4,000 gallons) and is of a compartmented design and construction requiring the installation of four or more separate vapor balance fittings.

580.55 It shall be unlawful for any person to cause or allow transfer of gasoline between a storage tank and a transport tank except under the following conditions:

580.551 The loading of all transport tanks, except those exempted under 580.54 of this section, shall be performed such that ninety percent by weight of the gasoline vapors displaced during filling are prevented from being released into the ambient air; providing that emissions from pressure relief valves shall not be included in the controlled emissions. This emission limitation will be met by vapor balancing in compliance with all provisions of this section.

580.56 It shall be unlawful for any person to cause or allow continued transfer of gasoline at any transfer point following occurrence of failure or leakage in any part of the vapor balance system, provided that occurrence of failure or leakage during loading or unloading of a transport tank shall not prevent the complete loading or unloading of the tank.

580.57 It shall be unlawful for any person to cause or permit the operation of a bulk gasoline plant or a transport tank without taking reasonable necessary measures to prevent the spilling, discarding in sewers, storing in open containers or handling of gasoline in a manner on the plant site that will result in evaporation to the ambient air.
