Section 10 CSR 10-2.260 - Control of Emissions During Petroleum Liquid Storage, Loading, and Transfer

Universal Citation: 10 MO Code of State Regs 10-2.260

Current through Register Vol. 49, No. 6, March 15, 2024

PURPOSE: This rule restricts volatile organic compound emissions from the handling of petroleum liquids in three (3) specific areas: petroleum storage tanks with a capacity greater than forty thousand (40,000) 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 that make transfers into stationary storage containers of certain sizes and types. This rule is necessary to reduce hydrocarbon emissions in the Kansas City metropolitan area that contribute to the formation of ozone.
