California needs cleaner air. Off-road construction equipment is
the second largest source of diesel pollution in the state,
accounting for 20% of particulate matter
(soot) and 16% of smog-forming Nitrogen Oxides (NOx). These
pollutants are two of the biggest pollution hazards for public
health in California and throughout the country.  I know you are
aware of the terrible hazards of diesel particulates and diesel
air pollution. I support the strong air standards for construction
equipment now before you. 

I understand from my scientific colleagues that this new rule
will:

-- Prevent 4,000 premature deaths;

-- Result in health benefits and reduced health care and
hospital visits of $18 to $26 billion;

-- Help bring the most polluted areas of the state, the Los
Angeles/Long Beach air basin and the San Joaquin Valley, into
attainment with federal air quality standards; and

-- By 2020, prevent 48 tons per day of NOx and 5 tons per day of
particulate air pollution from entering our air.

It is very important for you to take action to reduce diesel air
pollution from off-road vehicles and construction equipment.

Thank you for your attention to my comments.
