WASHINGTON (AP) - The government says the air in hundreds of
U.S. counties, including three in Mississippi, is simply too dirty
to breathe and ordered a multibillion-dollar expansion of efforts
to clean up smog.
The Environmental Protection Agency announced it was tightening
the amount of ozone, commonly known as smog, that will be allowed
in the air.
But the lower standard still falls short of what most health
experts say is needed to significantly reduce heart and asthma
attacks from breathing smog-clogged air.
EPA Administrator Stephen Johnson called the new limits "the
most stringent standards ever."
He said they will require 345 counties - out of more than 700
that are monitored - to make air quality improvements because they
now have dirtier air than is healthy to breathe.
In Mississippi, those are Harrison and Jackson counties on the
coast and Desoto County in the north.
