EPA squabbles with state over ship emissions

Just about a week after the Port of Long Beach and the city's harbor commission imposed a plan with truckers that would obligate the contractors to reduce emissions, a federal appeal court rejected a California's state regulation pollution from ships.
According to the Times, the ruling means the state has to get approval before imposing pollution restraints on the large diesel burning cargo ships and and other marine vessels that can be seen wading off the shores of Long Beach's harbor. Squabbles....
Long Beach and Los Angeles ports are responsible for an outpour of particulates, nitrogen oxide and sulfur, and soot from large heavy diesel burning engines on the tankers. The ships that come to the harbors are the source of heavy clouds of smog pollution that then is baked in the sun producing a low lying layer of ozone, a toxic poisonous gas that is invisible. The hard to see particulates can then enter the lungs causing asthma and other cardiovascular and respiratory problems in nearby cities and canyons where the smog ends up.
The smog and pollution has frequently caused the region to perform below federal health standards.
In an attempt clean the air quicker by stepping forward with harsher regulations and coming up with a plan to make the busy port areas one of the "greenest" regions in the country, state officials argued the state didn't need waivers from the Environmental Protection Agency. The federal agency has granted the state several waivers in since the 1970s allowing the state to regulate its own standards.
But this time the U.S. 9th Circuit Court of Appeals in San Fransisco said the state can't do that.
The EPA has denied the state's request to apply stricter standards before such as when the federal agency denied California from imposing standards to reduce emissions from automobiles.
But the whole controversy is over whether the regulations should be implemented or administered by the state or the federal government. Since Global Warming is commonly stressed as an international problem, many companies are confused as to who should be responsible, because inadvertently picking up the tab for lowering emissions means throwing out the old and in with the new. But some shipping companies have already taken steps to use on-shore power or lower the speed or use low sulfur fuels.But my question is if the state can't regulate it's own ports, then who will, obviously the federal government doesn't care, because it wouldn't have been this way in the first place. California is constantly taking harder steps toward cleaning up the ships, trucks and cars that make our air polluted.
You can smell it!
And there's also something else I can smell too. We should stop worrying about who is in charge and bickering over who is going to stop it and just work together to do it.
If the state needs a waiver, then get a waiver, but I don't see why we should slow down our plans for a greener and healthier world, when that should have been the plan from get go!
