Relating to: a tax credit for aviation biofuel manufacturing, authorizing the state to contract public debt for an aviation biofuel project grant, and making an appropriation. (FE)
AB 619 creates a $150 million grant program to fund aviation biofuel manufacturing projects in Wisconsin, funded through state public debt issuance. The bill requires grantees to use facilities exclusively for aviation biofuel production (with limited exceptions for other biofuels if 80% of output is aviation fuel), source 80% of biomass locally, and invest at least $1.5 billion in aviation biofuel manufacturing within five years. It directly affects companies building such facilities and the Department of Natural Resources, which administers the grants. The program aims to support the state's forest products industry and create jobs, with strict repayment terms if grantees fail to meet requirements.
