Current Regulations: For the 1998 summer, Birmingham required federal RFG or a summer max. 7.0 psi RVP gasoline with a maximum summer avg. of 310 ppm sulfur content. For the summers of 1999 through 2003 in Birmingham, Alabama changed the summer sulfur standard to a maximum 150 ppm average. Effective 4/1/01, there was a sulfur content summer cap of 500 ppm in Birmingham. See Alabama's Administrative Code 335-3-20. Effective 4/20/12, EPA approved a SIP revision to remove the state requirement for summer maximum 7.0 psi RVP gasoline in Birmingam; the federal 7.8 psi RVP regulation will apply (see 77 FR 23619; 4/20/12). 

Effective on January 1, 2004, these gasoline sulfur standards for Birmingham were superseded by more stringent national, federal gasoline sulfur regulations.

In a letter dated 9/5/08, EPA issued a waiver of the low RVP and gasoline sulfur averaging requirements in Birmingham through 9/15/08 to address a fuel supply emergency caused by Hurricane Gustav. The Agency also temporarily waived the requirement that ethanol/gasoline blends must have 9-10 vol% ethanol to qualify for the one psi RVP allowance. EPA waived summer RVP gasoline requirements throughout the state in a letter dated 9/11/08.

In a letter dated 9/4/12, EPA waived requirements for low RVP gasoline through Sept. 15 as a result of Hurricane Isaac and allowed 11.5 psi RVP gasoline if supplies of low RVP gasoline are not available.

In a letter dated 8/30/17, to address a fuel supply emergency caused by Hurricane Harvey, EPA allowed 11.5 psi RVP gasoline throughout the state through September 15.

Alabama Administrative Code Chapter 80-1-16 lists gasoline standards and Chapter 80-1-18 lists diesel standards enforced by the AL Department of Agriculture and Industries, Weights and Measures Section.
