I am writing in support of stronger air standards
for California's construction equipment:

-- 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.

-- These health impacts result in tens of thousands of premature
deaths in the U.S. from heart and lung disease annually, as well
as hospital admissions, emergency room visits, absences from
school or work, and restricted activities related to asthma
attacks. Children are especially vulnerable because their lungs
are still developing.

This new rule to strengthen state air standards and reduce air
pollution from construction equipment, the "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 support this rule.
