Farmers are worried the partial federal government shutdown might further delay a proposal to allow gasoline with 15 percent ethanol to be sold year-round.

The plant is expected to start operations in 2020 and produce 80 million gallons of ethanol each year.

President Donald Trump mentioned the possible policy shift during a visit to Iowa last week. He said the Administration is working on rolling back restrictions that ban higher ethanol blended gasoline during summer months.

President Donald Trump reportedly agreeing to allow year-round sales of gasoline with 15 percent ethanol could be food for Indiana corn growers, but environmentalists aren’t thrilled.

Indiana is among 21 states that will receive federal grants to add more service station fuel pumps that can handle gasoline blends with more than 10 percent ethanol.

Noble Americas bought the plant two years ago after a previous owner went bankrupt and the plant had to close. On Wednesday, Noble announced that the plant had begun shipping fuel.
