The Environmental Protection Agency on Wednesday tightened limits on fine industrial particles, one of the most common and deadliest forms of air pollution, for the first time in a decade.
Public health organizations said the pollution rules would save lives and strengthen the economy by reducing hospitalizations and lost workdays.
Fine particulate matter, which can include soot, can come from factories, power plants and other industrial facilities.
The new rule lowers the annual standard for fine particulate matter to nine micrograms per cubic meter of air, down from the current standard of 12 micrograms.
will use air sampling to identify areas that do not meet the new standard.
