State leaders announced a partnership with the petroleum industry that they said will increase fuel supply, lower gas prices and resolve an ongoing feud with Idaho. The announcement comes after weeks of tension between Utah and Idaho leaders over a plan floated by Utah lawmakers to tax fuel exports. Officials in Idaho said that could have raised gas prices there. Instead of taxing exports, the Legislature plans to cut the state gas tax by 15% while working with the oil and gas industry to increase the supply of fuel at Utah's refineries, House Speaker Mike Schultz, R-Hooper, announced Monday.
