§ 52.787 Gasoline transfer vapor control.

(a) Gasoline means any petroleum distillate having a Reid vapor pressure of 4 pounds or greater.

(b) This section is applicable in the County of Marion, Indiana (including all cities, towns and municipal corporations therein).

(c) No person shall transfer or permit the transfer of gasoline from any delivery vessel into any stationary source container with a capacity greater than 250 gallons unless such container is equipped with a submerged fill pipe and unless the displaced vapors from the storage container are processed by a control system that prevents release to the atmosphere of no less than 90 percent by weight of organic compounds in said vapors displaced from the stationary storage container location. The control system shall include one or more of the following:

(1) A vapor-tight return line from the storage container to the delivery vessel and a system that will ensure that the vapor return line is connected before gasoline can be transferred into the container. If a “vapor-balance return” system is used to meet the requirements of this section, the system shall be so constructed as to be readily adapted to retrofit with an adsorption system, refrigeration-condensation system or equivalent system connected to the stationary storage container.

(2) Refrigeration-condensation sys- tem or adsorption system connected to the stationary storage container.
