Please support stronger air standards for California's construction
equipment.

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.

Particulate air pollution or soot can be inhaled and reach deep
into the lungs. These tiny particulates can enter the circulatory
system and damage blood vessels. Particulate pollution is
associated with heart attacks, irregular heartbeat, asthma
attacks, reduced lung function and bronchitis.

The new rule regarding "In-Use Off-Road Diesel Vehicles" 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.

I urge you to support stronger air standards for California's
construction equipment.

Thank you.
