Monitoring of biofuel, air emissions, wastewater, and coproducts for the presence of certain chemicals required; voluntary biomonitoring of biofuel plant employees provided; and money appropriated.

HF 1481 requires biofuel plants in Minnesota to monitor ethanol, biodiesel, and advanced biofuel production for neonicotinoid pesticides and perfluoroalkyl substances (PFAS) in the fuel, air emissions, wastewater, and byproducts like dried distillers grains. It mandates that plants maintain permanent records of these tests and make them available to the public and regulators. The bill also provides for voluntary biomonitoring of biofuel plant employees to assess workplace exposure to these chemicals, with $250,000 appropriated to the Department of Health for this purpose. The law appropriates a total of $1.1 million across state agencies for implementation, including $500,000 for wastewater and air monitoring under the Pollution Control Agency.
