The legislative bill HF No. focuses on the environment by proposing the repeal of certain clean car rules in Minnesota. These rules, specifically parts 70230150, 70230200, 70230250, and 70230300, previously set standards for low-emission and zero-emission vehicles based on California regulations. They covered various aspects from definitions, emission standards, exemptions, and requirements for vehicle manufacturers such as emission control labeling and recalling of non-compliant vehicles.

The repeal of these rules would reverse the regulations that were aimed at reducing air pollution from vehicles within Minnesota by following California's stricter emission standards. This legislative change could potentially affect air quality and emissions control efforts in the state.
