The Missouri Renewable Fuel Standard Act

On January 1, 2008, the Missouri Renewable Fuel Standard becomes effective. Under this standard, all gasoline offered for sale in Missouri must contain 10% ethanol.

A few exemptions to the standard will allow gasoline without ethanol to be sold:

Although premium is exempted from the requirement, it may be blended with ethanol.

Missouri does not require ethanol labeling on gasoline dispensers. Therefore, if a consumer has a specific application that requires a fuel without ethanol, the consumer must purchase premium unleaded gasoline with an octane of 91 or higher that is also advertised as not containing ethanol.

Retail Service Station Operators

It is important for service station operators and wholesale consumer users to prepare storage tanks by removing water and sediment and installing 10 micron filters before the introduction of any ethanol blends into these tanks. This will ensure the quality of the product is preserved.
