States that are looking at regional agreements to reduce air pollution could face legal challenges.
The Great Lakes Radio Consortium’s Chuck Quirmbach reports:


Some states are upset with the pace of federal efforts to address climate change. So, they’re
considering teaming up on their own. For example, New York and some other eastern states plan
to begin a trading program in 2009, aimed at reducing carbon dioxide emissions that contribute to
global warming.


Robert Percival is an environmental law professor at the University of Maryland. He says the
regional efforts must proceed carefully.


“If the federal government fails to take action against a major problem there’s no problem letting
the states step in as long as they do so in a non-discriminatory way.”


In other words, the states can’t interfere with interstate commerce, by ruling against utilities or
other firms that produce products outside their regional collaboration. If the states do
discriminate, they’d need to get approval from Congress, and with Capitol Hill and the White
House currently on the same page on many issues, it isn’t clear federal lawmakers would back the
states.

A new study indicates that air pollution dropped significantly the day after last year’s
power blackout in the Northeast and upper Midwest. The Great Lakes Radio
Consortium’s Lester Graham reports:


Researchers at the University of Maryland took air samples during the blackout last
August. They found air pollution was dramatically reduced downwind of the blackout
area. They say the better air quality was at least in part due to more than 100 coal-
burning power plants shutting down.


Scott Segal is with the Electric Reliability Coordinating Council, an electric utilities
industry group. He suggests power plants were only part of the reason.


“Not only do power plants go off line. Typically, people don’t go to work, which means
that automobile traffic is depressed. In addition, there are 20 industrial sectors that are
non-utilities that utilize coal-fired capacity or other fossil fuels that are sources of sulfur
dioxide and those are all taken off line in the event of a blackout.”


But the researchers maintain the study shows power plants play a dominant role in haze
and ozone pollution.


For the Great Lakes Radio Consortium, this is Lester Graham.
