Statewide Labeling Requirements for Pumps
Dispensing Gasoline Containing MTBE

On June 24, 1999, the Air Resources Board (ARB) approved a statewide regulation requiring the prominent labeling of retail pumps dispensing gasoline containing methyl tertiary butyl ether (MTBE). The regulation was adopted pursuant to Governor Davis’ Executive Order D-5-99 which, among other things, directed the ARB to adopt labeling regulations for gasoline containing MTBE in order to allow consumers to make an informed choice as to the type of gasoline they purchase.

Any pumps that dispense gasoline containing the MTBE additive must be labeled. If you need labels an order form is included at the bottom of this web page.
