Utah Admin. Code R307-328-5 - Stationary Source Container Loading

(1) No person shall transfer or permit the transfer of gasoline from any gasoline cargo tank into any stationary storage container with a capacity of 250 gallons or greater unless such container is equipped with a submerged fill pipe that extends to no more than 12 inches from the bottom of the storage tank for fill pipes installed on or before November 9, 2006, and no more than six inches from the bottom of the storage tank for fill pipes installed after November 9, 2006, and at least 90% of the gasoline vapor, by weight, displaced during the filling of the stationary storage container is prevented from being released to the atmosphere. This requirement shall not apply to:

(a) the transfer of gasoline into any stationary storage container of less than 550 gallons used primarily for the fueling of implements of husbandry if such container is equipped with a permanent submerged fill pipe;

(b) the transfer of gasoline into any stationary storage container having a capacity of less than 2,000 gallons which was installed before January 1, 1979, if such container is equipped with a permanent submerged fill pipe; or

(c) the transfer of gasoline to storage tanks equipped with floating roofs or their equivalent which have been approved by the director.

(2) The 90% performance standard of the vapor control system shall be based on operating procedures and equipment specifications. The design effectiveness of such equipment and the operating procedure must be documented and submitted to and approved by the director.

(3) Each owner or operator of a gasoline storage tank or the owner or operator of the gasoline cargo tank subject to Subsection (1) shall install vapor control equipment, which includes:

(a) vapor return lines and connections sufficiently free of restrictions to allow transfer of vapor to the gasoline cargo tank or to the vapor control system, and to achieve the required recovery;

(b) a means of assuring that the vapor return lines are connected to the gasoline cargo tank, or vapor control system, and storage tank during tank filling;

(c) restrictions in the storage tank vent line designed and operated to prevent:

(i) the release of gasoline vapors to the atmosphere during normal operation; and

(ii) gauge pressure in the gasoline cargo tank from exceeding 18 inches of water and vacuum from exceeding 6 inches of water; and

(d) a pressure vacuum relief valve on the vent line of each storage tank that:

(i) is set to open at eight oz. per square inch or greater pressure and four oz. per square inch or greater vacuum; and

(ii) is tested initially and every three years thereafter using the California Air Resources Board Test Procedure 201.1E.

(e) Test records shall be submitted to the director.
