MINOR
The bill was amended to limit the biodiesel fuel requirement to specific counties with populations between 200,000 and 300,000, rather than applying to the entire state. The effective date was also moved forward from the year 3000 to 3050, and the report submission deadline was adjusted to align with the 2027 legislative session.
Scope change
The requirement now applies only to counties with a population of more than 200,000 but less than 300,000 persons, excluding other areas of the state.
SCOPE
The fuel mandate was narrowed from statewide application to only counties with populations between 200,000 and 300,000.
TIMELINE
The effective date was changed from July 1, 3000, to July 1, 3050, and the report deadline was updated to twenty days before the 2027 session.
REQUIREMENT
The statutory language was updated to specify that the rule applies to 'any county' meeting the population criteria rather than the 'State'.
