To Whom It May Concern:

I am in favor of the ARB's new rule to reduce air pollution from
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.

Exposure to smog can have serious effects on respiratory
health. Inflammation and irritation of the respiratory tract can
cause shortness of breath, throat irritation, chest pains and
coughing, and lead to asthma attacks, hospital admissions and
emergency room visits.

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.

I support the new rule because I believe it will prevent 4,000
premature deaths;Result in health benefits and reduced health care
and hospital visits; Help bring the most polluted areas of the
state 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.
