Latest group to file suit against EPA: Oil refiners

The latest suit filed against the Environmental Protection Agency over its new rule allowing the sale of E15 gasoline was filed by the National Petrochemical and Refiners Association Monday, according to the Seattle Times.

The rule allows gas stations to begin selling the ethanol fuel blend for vehicles built since 2007. 

The group claims the agency does not have the authority under the Clean Air Act to approve a plan for some engines but not all.

Another group comprised of engine manufacturers filed suit against the EPA over the E15 rule in mid December.
