Section 21.85.33. Motor fuel and antifreeze tests and standards.

In the interest of uniformity, the tests and standards for motor fuel, including but not limited to renewable fuels such as ethanol blended gasoline, biodiesel, biodiesel blended fuel, and components such as an oxygenate, raffinate natural gasoline and motor vehicle antifreeze shall unless otherwise required by statute be those established by the American Society for Testing and Materials (ASTM) in effect on July 1, 2013, with the exception of ASTM D4814-13 for the distillation of gasoline for ethanol blended gasoline classified as higher than E-10 and up to E-50. Diesel fuel which does not comply with ASTM international specifications may be blended with biodiesel, additives or other diesel fuel so that the finished blended product does meet the applicable specifications. In addition, a motor fuel that contains more than one-half of 1 percent of methyl tertiary butyl ether (MTBE) by volume shall not be sold, offered for sale, or stored in Iowa.

This rule is intended to implement Iowa Code sections 208A.5, 208A.6, 214A.2 as amended by 2013 Iowa Acts, House File 458, and 215.18.
