Prohibits fuel oil, grade number four in any building or facility in the state

This bill prohibits the use of fuel oil, grade number four, in any building or facility within the state starting July 1, 2028. The law aims to reduce emissions by banning this specific type of heating fuel, though it allows local governments to pass stricter rules if they choose. The ban applies to all structures across the state, but the legislation does not specify alternative energy sources that must be used instead.
