| Comment | 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.
Result in health benefits and reduced health care and
hospital visits of $18 to $26 billion;
"In-Use Off-Road Diesel Vehicles" rule
will result in health benefits and reduced health care and
hospital visits of $18 to $26 billion and 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
