PURPOSE: This rule restricts volatile organic compound emissions from the handling of petroleum liquids in five specific areas: petroleum storage tanks with a capacity greater than forty thousand gallons, the loading of gasoline into delivery vessels, the transfer of gasoline from delivery vessels into storage containers, gasoline delivery vessels and the fueling of motor vehicles from storage containers. This rule is required to achieve the federally mandated reduction of hydrocarbon emissions in the St. Louis metropolitan area that contribute to the formation of ozone.

However, this consideration will not affect recording of defects or enforcement action; and

1. 2. After repairs are made and notifica-

tion by the plant is received, the department or local agency shall reinspect all defects found in official Stage II inspections. Failure by an installation to notify the department of repairs and request reinspection within fifteen (15) days of repair may result in enforcement action.

1.
