Nitrogen Oxides: "Appeals Court Upholds EPA Air Quality Rule"

"A federal appeals court upheld a new Environmental Protection Agency rule to limit nitrogen dioxide emissions near major roadways, in a defeat for the oil industry, which said the rule went beyond what was necessary to protect public health."

"Tuesday's decision by the U.S. Court of Appeals in Washington, D.C., is a victory for the Obama administration and environmental groups that supported the 2010 rule, which limits exhaust that could remain in the air for a one-hour period.

The 100 parts-per-billion limit was intended to reduce smog from such sources as car exhaust pipes and factories; it was more stringent than a standard dating from 1971.

Nitrogen oxides have been linked to respiratory problems, especially in children and people with asthma, according to the EPA."
