MONROE, Mich. — A Michigan utility spent $65 million last year replacing key parts at the state's largest coal-fired power plant. When regulators found out, they hauled the company into court for what it didn't do: Spend millions more at the same time to greatly eliminate air pollution.
The fight with DTE Energy isn't an isolated one. The U.S. Environmental Protection Agency and the Justice Department are aggressively suing electric utilities across the Midwest to get them to install the latest technology to capture smog-causing emissions.
The legal action is the latest shot in a decades-long conflict over bringing the utilities in line with the Clean Air Act. When Congress passed tougher standards in 1977, it allowed the industry to wait until older plants underwent a major overhaul before acquiring new anti-pollution equipment. The idea was that upgrades would be made gradually.
But more than three decades later, about half of U.S. coal-fired units — roughly 600 — lack advanced controls, EPA says. And years have been consumed in clashes among utilities, regulators and environmental groups over exactly what constitutes an overhaul and what is merely maintenance.
For people in Michigan and three other Midwestern states, court battles over pollution equipment could make a difference in the purity of air they breathe and the cost of electricity they use. The DTE case is set for trial this fall.
"What you're seeing is EPA's renewed vigor in enforcement of the Clean Air Act," said Cynthia Giles, an EPA assistant administrator. "The controls we're seeking to make companies install cost money. There are reasons for the industry to be pushing back. It's our job to insist on compliance."
In January, the EPA also sued utilities in Pennsylvania and Missouri. A case involving six coal-burning plants in Illinois is also pending. Meanwhile, there have been at least seven settlements since 2009 in Kentucky, Ohio, Indiana and Kansas, with remedies ranging from cleaner fuel to millions of dollars in fines and pollution controls
