I think it's about time those numbnuts in California stop raising parts per millions regulation, and start re-inventing L.A. I mean, Los Angeles is a car city. Traffic jams are a fact of everyday life. Public Transportation a failure. Biking is either hazardous or infeasible. How abou drafting a city block plan where coomercial zones are integrated with residential ones? That way people can walk to work. Enact ordinance for alternative transports. Provide paths and parking spaces for bicycles, quadcycles, and Segways. Give a straight eco-friendly transportation path to Industrial zones.
Take a look at how other countries do it. They build things with economy in mind. No wasted resources is better than recycling.
