Gov. Jan Brewer signed the HB2617, which prevents state agencies from adopting rules more restrictive than federal requirements, unless they get legislative approval. But she vetoed HB2237, that would have promoted tungsten-based light bulb manufacturing in Arizona as a challenge to federal authority. This would have required tungsten mining and milling in Arizona. [right, a tungsten filament for incandescent bulbs]
