The E15 standard calls for 15% ethanol per gallon of gasoline to reduce the nation’s dependence on fossil fuels. Currently, the government limits the amount of ethanol to 10% (the E10 standard) and has done so for the past 30 years. The concerns are that ethanol does not help the environment at all since it is not as efficient as gasoline, it requires the use of corn crops that could otherwise feed people, farmers overfertilize to get maximum yield and because the Department of Energy still has not reached conclusions as to which biofuel is the best for our needs.
The American Coalition for Ethanol is trying to convince the EPA to set this new standard. A final decision is pending.
Good question, Kristina. There is actually something called the UL 87 standard, which says that gasoline dispensers may contain up to 15% ethanol in the gasoline, among other things. UL is short for Underwriters Laboratories, an independent safety inspection company certified by OSHA. There was some debate over the safety of gas containing up to 15% ethanol, but UL stated last year that “equipment certified to UL 87 to dispense ethanol blends with a maximum ethanol content of 15 percent should not result in critical safety concerns.”
Hope this helps!
