I support stronger air standards for California's construction
equipment, such as the proposed new rule for "In-Use Off-Road
Diesel Vehicles."

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.

Exposure to smog can have serious effects on respiratory health.
Particulate air pollution or soot can be inhaled and reach deep
into the lungs and 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 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.
