A bulk gasoline loading terminal operation shall use the following control techniques:

1. (a) VOC vapor emitted from tank truck loading operations at a bulk gasoline loading terminal shall be collected and controlled by equipment limiting the total VOC emission rate from the controlled operations over any one-hour period to 80 mg of VOC per liter, equivalent to 0.08 ounces per cubic foot, of gasoline loaded;

2. (b) All equipment such as pumps, tanks, couplings, hoses, and seals, used in loading gasoline trucks and controlling VOC emissions during loading, shall be maintained in leak-tight condition, as determined through test and maintenance procedures specified in the following document published by EPA:

   EVALUATION OF VAPOR LEAKS AND DEVELOPMENT OF MONITORINGPROCEDURES FOR GASOLINE TANK TRUCKS AND VAPOR PIPING

   Document number EPA-450/3-79-018

   April, 1979; and

3. (c) The bulk gasoline loading terminal shall be equipped with a vapor control system capable of complying with (a), above, and consisting of one of the following:

   1. (1) An adsorber or condensation system which processes and recovers at least 90% by weight of all vapors and gases from the devices being controlled;
   2. (2) A vapor collection system which directs all vapors to a fuel gas system and destroys at least 90% by weight all vapors and gases from the devices being controlled; or
   3. (3) A control system demonstrated to have control efficiency equivalent to or greater than (1) or (2) above, and approved by the director in accordance with the procedures of Env-A 809.01.
