This has been coming for several years now.  The legislature passed the law
adopting the CARB standards for Washington State several years ago and they
have slowly been implementing that.
Hmm, any lawyers out there looking for a good class action law suit?  How
can residents of WAshinton have the laws and rules of another state imposed
on them when they would have no standing to challenge such laws in the
California courts?  And what effect does such a law have on any appeal or
judicial review of such laws and regulations have in Washington State?  I'll
bet the drafters of the Washington law think they have an answer for that
but I bet a good attorney could shove it down their throats.
