PIERRE, SD -
South Dakota is allowing the sale of 85-octane gasoline under emergency rules implemented Monday by the state Department of Public Safety.
Officials say a public hearing will be held July 20 to discuss permanent rules for sale of the product, which is illegal under state law.
Gov. Dennis Daugaard asked for the emergency rules because petroleum marketers are worried about possible fuel shortages.
The temporary rules will require retailers to post cautionary labels asking consumers to refer to an owner's manual before fueling.
Octane is a measure of fuel performance. A higher octane level indicates better performance. Many manufacturers recommend a minimum of 87 octane fuel.
South Dakota Attorney General Marty Jackley issued an opinion last month stating that under current rules, 85-octane gasoline can't be sold in the state.
