You might have heard of this one, it would make all the curently exempt diesel vehicles that a lot of small business contractors use get smogged. One guy I talked to told me that it could have the effect of causing gross diesel polluters to get their engines fixed or replaced and that would cost the small business delivery trucks, construction contractors, etc etc to raise their rates to counter act the higher cost of actually preventing their diesel delivery and work trucks from polluting.
