EPA proposes to include Southern Maine in the Federal Reformulated Gasoline Program

Green Car Congress

AUGUST 22, 2014

EPA is proposing , at the request of the State of Maine, to require the sale of reformulated gasoline ( RFG ) in York, Cumberland, Sagadahoc, Androscoggin, Kennebec, Knox and Lincoln counties in southern Maine starting in June 2015. About 30% of gasoline sold in the US is reformulated.

The US Environmental Protection Agency (EPA) has determined that the systems used at gas station pumps to capture harmful gasoline vapors while refueling cars can be phased out. Since 1994, gas stations in areas that do not meet certain air quality standards have been required to use gasoline vapor recovery systems.

Higher octane fuels can lead to higher compression ratios which in turn can lead to more efficient gasoline engines and reduced fuel consumption. With turbocharged gasoline engines, there is a double benefit: higher compression ratios and increased boost. Currently, the Clean Air Act limits the volatility of gasoline to 9.0
