Notwithstanding anything to the contrary in section 10d, the director shall establish the vapor pressure as 9.0 pounds per square inch (psi) for retail outlets during the period beginning June 1 through September 15 of each year, except for dispensing facilities in counties where the director establishes the vapor pressure as 7.0 psi or 7.8 psi in the year 2007 and thereafter. As used in this act, "vapor pressure" means the vapor pressure of gasoline or gasoline oxygenate blend as determined by ASTM test method D6378 or D5191 or an ASTM method approved by the department.
(5) In establishing additive and grading standards the director shall adopt the latest standards for gasoline established by the American society for testing and materials Society for Testing and Materials and shall adopt the latest standards for gasoline established by federal law or regulation. The standards established by the director shall must not prohibit a gasoline blend that is permitted by a valid waiver granted by the United States environmental protection agency E.P.A. pursuant to the fuel or fuel additive waiver in section 211(f)(4) of part A of title II of the clean air act, 42 USC 7545, and the ethanol waiver of 1.0 psi in section 211(h)(4) of part A of title II of the clean air act, 42 USC 7545, if the gasoline blend meets all of the conditions set forth in the waiver.

The director retains the authority to implement the vapor pressure 7.0 psi requirement or 7.8 psi requirement in areas where it is determined necessary to attain or maintain national ambient air quality standards. If an area of the state that is required to use a low vapor pressure fuel of 7.8 psi or 7.0 psi has been redesignated by the United States environmental protection agency as in attainment of national ambient air quality standards, and the Michigan department of environmental quality has demonstrated that maintenance of the national ambient air quality standards can be achieved without the use of low vapor pressure fuel, the director may, with the approval of the United States environmental protection agency, terminate the low vapor pressure fuel requirement for that area.
(1) The director may implement requirements in conformity with federal law including, but not limited to, section 211(h) of part A of title II of the clean air act, 42 USC 7545, and the vapor pressure standards and waivers described in 40 CFR 1090.215.
