The first new U.S. standard for nitrogen dioxide in at least 35 years was upheld by a federal appeals court, which said the Environmental Protection Agency had the authority to attempt to improve air quality around the nation’s busiest roadways. [Businessweek]
A three-judge panel of the U.S. Court of Appeals in Washington today threw out a challenge by the American Petroleum Institute to regulations restricting the peak amount of nitrogen dioxide, or NO2, from tailpipes and smokestacks that can be present in the air during a one-hour period. Levels of the toxic gas are limited to a one-hour standard of 100 parts per billion.
“Because the record adequately supports the EPA’s conclusion that material negative effects result from ambient air concentrations as low as the 100 ppb level, we cannot conclude that the agency was arbitrary and capricious” in adopting that standard, U.S. Circuit Judge Douglas Ginsburg wrote for the court.
