WASHINGTON -- The Environmental Protection Agency is proposing new air quality standards that would lower the amount of soot allowed from diesel trucks, buses, power plants and other sources.
The long-delayed rule, to be made public Friday, responds to a court order that required the Obama administration to update air quality standards under the Clean Air Act. Administration officials described the rule to The Associated Press on condition of anonymity because it has yet to be announced.
Eleven states, including New York and California, filed suit earlier this year to force a decision. The states and the American Lung Association say current standards jeopardize public health. Soot has been linked to thousands of premature deaths each year, as well as aggravation of respiratory illnesses, heart attacks and strokes.
