He said he's concerned about the number of specialty blends of gas available, and that prices surge when stations switch to seasonal blends.
Blunt says he wants to fix the price increase by allowing communities to use whatever fuel they have on hand.
Currently, the Clean Air Act requires stations to switch blends.
"I'm saying we don't need to have anymore of those blends than we absolutely have to have," Blunt said.
"It may be possible for a city to have the blend of gas they need to meet the clean air standard. But every city doesn't need their own unique blend of gas."
Blunt also said the government needs to look closer at using American resources for energy.
