Direct Final Ruling Approving Arizona Summertime Gasoline Volatility Limit for the Phoenix Area

On May 28, 1997, EPA signed a direct final rule approving the State's request to establish a summertime gasoline Reid Vapor Pressure (RVP) limit of 7.0 pounds per square inch (psi) distributed in the Maricopa County (Phoenix) metropolitan area.

Arizona has lowered the summertime RVP limit for this area to reduce emissions of volatile organic compounds (VOCs). Arizona's fuel requirement is not preempted by federal fuels requirements because EPA is finding that the control measure is necessary for the Maricopa area to attain the national ambient air quality standards (NAAQS) for ozone and is approving the measure into the State Implementation Plan.
