Contractors and other operators of off-road diesel equipment will exceed ambitious new emissions targets set by California officials, according to new state figures released Tuesday by AGC.  New data from the California Air Resources Board indicates there is no need to impose costly new "diesel retrofit" rules forcing contractors to purchase new equipment before 2014.
