Washington -The U.S. Environmental Protection Agency outraged environmental groups Tuesday by unveiling new standards for airborne soot emissions that ignored advice from its own scientists.
Tens of thousands of deaths each year are caused by sooty particles emitted by sources that include combustion engines, coal-fired power plants and even household fireplaces. The particles can be as small as 1/30th the diameter of human hair. The EPA is required to revise allowable standards for them every five years.
A scientific advisory panel that the EPA assembled to review particle pollution standards suggested reducing the yearly average amount it allows in the air, and cutting the peak levels it permits from 65 micrograms per cubic meter to between 30 and 35 micrograms.
The EPA proposed leaving the allowable yearly average intact at 15 micrograms, and cutting allowable peaks to the weakest recommended threshold: 35 micrograms. EPA also proposed eliminating yearly standards it allows for larger airborne dust...
