"The Environmental Protection Agency (EPA) said Monday it will allow gasoline containing a higher percentage of ethanol to be used year-round.

The move follows President Trump’s energy emergency declaration, which required the EPA to consider allowing year-round high ethanol gas, known as E15.

This type of gasoline is typically restricted in the summer due to concerns about smog — which can form more easily from evaporation in the heat.

However, the government can choose to issue a waiver to allow E15 gas nationwide in the summer."
