PURPOSE: This regulation further controls evaporative hydrocarbon emissions from the handling of petroleum liquids in three specific areas— petroleum storage tanks with a capacity greater than forty thousand gallons, the loading of gasoline into delivery vessels and the transfer of gasoline from delivery vessels into stationary storage containers. Exemptions are provided for facilities loading less than or equal to six hundred thousand gallons of gasoline per month and for transfers made into stationary storage containers of certain sizes and types. This regulation is required in order to reduce hydrocarbon emissions in the Kansas City metropolitan area which contribute to the formation of oxidants.
