JEFFERSON CITY, Mo. —
As President Barack Obama prepares to announce tougher new air quality standards, lawmakers in several states already are trying to blunt the impact on aging coal-fired power plants that feed electricity to millions of consumers.
The push against Obama’s new carbon emission standards has been strongest in some states that have large coal-mining industries or rely heavily on coal to fuel their electricity. State officials say the new federal regulations could jeopardize the jobs of thousands of workers and drive up the monthly electric bills of residents and businesses.
It remains to be seen whether new measures passed by the states will amount to mere political symbolism or actually temper what’s expected to be an aggressive federal effort to reduce the country’s reliance on coal. But either way, states likely will play a pivotal role, because federal clean air laws leave it up to each state to come up its own plan for complying with the emission guidelines.
The proposed Environ-mental Protection Agency rules to be announced today could be the first to apply to carbon dioxide emissions at existing power plants. Coal is the most common fuel source for the nation’s electricity and, when it’s burned, is a leading source of the greenhouse gasses that trap heat in the atmosphere and contribute to climate change.
Without waiting to see what Obama proposes, governors in Kansas, Kentucky, Virginia and West Virginia have signed laws directing their environmental agencies to develop their own carbon emission plans that consider the costs of compliance at individual power plants. Similar measures recently passed in Missouri and are pending in the Louisiana and Ohio legislatures.
