Storage tank emissions from venting are primarily volatile organic compounds (VOC) which are considered hazardous air pollutants (HAP). At gas stations, fuel vapors are released into the atmosphere from storage tanks through vent pipes. This is done so that during the subsequent gas freeing no portion of the tank atmosphere is brought within the flammable range. The air being introduced into the gas tank while pumping gas apparently has nowhere to go. Mortison Vent Capacities are listed on Table H, page 12. to Step 4.
