The Washington House of Representatives has now agreed to go along with the state senate’s version of clean-car legislation, as the Post-Intelligencer reports. So the legislative hurdles are largely cleared. My lingering worry is that the Washington law will get thrown out in court.

The Washington law no longer simply adopts the California standards in their entirety, as any state is allowed to do under the US Clean Air Act. Instead, it adopts most of the California standards. I’m no lawyer and my knowledge of the legal issues is second hand. But I didn’t think that was allowed.

Can anyone shed some light?
