Under the bill, the state would guarantee up to $2,500 in loans to purchase propane or other heating supplies and pay down interest on the loans. The borrower's household income couldn't exceed 200 percent of their county median household income.
The Joint Finance Committee approved the bill unanimously Wednesday, clearing the way for a vote in the full Assembly.
Gov. Scott Walker last month declared a state of emergency due to the propane shortage and established a $3 million loan guarantee program for propane dealers.
