(b) The Commissioner of Motor Vehicles shall not enter into a negotiated inspection agreement or agreements to provide for the emission inspection of a motor vehicle which would prevent the implementation of a variable fee structure determined by the mileage and the extent of pollutants in the exhaust emissions of the vehicle.
