Please vote in favor of the new rule to reduce air pollution from
California's construction and agricultrual equipment.  ARB has
courageously passed other rules to improve California's air
quality by reducing emissions from personal vehicles. 
Agricultural and construction equipment has been overlooked for
too long.  We have the technology to modify existing equipment,
but most businesses will not make the change unless all have to
meet the same standard.

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.

Citizens of California are worried about air quality and depend
upon ARB to provide solutions to make California a healthier place
to live.

Thank you.
