From NPR News this is ALL THINGS CONSIDERED. I'm Audie Cornish.
MELISSA BLOCK, HOST:
And I'm Melissa Block. The Environmental Protection Agency got a lot of what it wanted in a Supreme Court ruling today. The court gave the agency the OK to regulate greenhouse gases emitted from new and modified plants and factories. That decision was made by a 7 to 2 vote. But in a separate 5 to 4 vote, justices rejected the EPA's broad assertion of regulatory power under another section of the Clean Air Act. NPR's Nina Totenberg reports.
NINA TOTENBERG, BYLINE: You might call the outcome in this case the 83 percent solution or as Justice Anthony Scalia put it for the majority, the EPA got almost everything it wanted. The EPA had sought authority to regulate large polluters responsible for 86 percent of all greenhouse gases emitted from stationary sources like utility plants and factories. Instead it won power to regulate 83 percent of those omissions. But before the court reached that bottom line, Scalia's opinion lambasted the EPA for trying to rewrite a statute in order to make it more sensible. We shudder to think what the effect on democratic governance would be if such a rewriting were permissible, he said. Harvard professor Richard Lazarus specializes in environmental law.
RICHARD LAZARUS: This is sort of reminiscent of Macbeth's final soliloquy. There's a lot of sound and fear signifying nothing. I mean, EPA's authority and ability to use the Clean Air Act to address climate change is essentially unchanged after today.
TOTENBERG: Today's ruling stems from the court's 2007 decision declaring that under the Clean Air Act, the EPA could regulate carbon dioxide emissions from cars, trucks and other mobile sources. After that decision, the EPA sought to regulate stationary sources of greenhouse gas pollution. Things like utility plants, steel plants and factories. But this particular provision of the law was quite specific about what places could be regulated - those that emit more than 100 tons of pollutants each year or, in some cases, 250 tons. Applying that to greenhouse gases, the law would require permits for just about every apartment, house, mall, school and church. Enforcement would cost tens of billions of dollars and construction would grind to a halt nationwide. The EPA didn't want that, so it, quote, "tailored the reach of the statue" and required permits only for those planes that omitted 100,000 tons of pollution a year instead of 100. Industry challenged the relations hoping to get rid of all greenhouse gas regulations for stationary structures, but today it appeared to have won the battle and lost the war. A five justice conservative majority agreed that the EPA could not rewrite that particular section of the Clean Air Act to suit its bureaucratic policy goals. But, and this is a big but, a seven justice majority said that under a different provision of the Clean Air Act, if a plant already has to get a permit for pollutants, generally that will include greenhouse gases. And as the court majority noted, the difference in the reach of these two provisions is only 3 percent. Case Western University law professor Jonathan Adler is director of the Center for Business Law and Regulation. He calls today's ruling little more than a bump in the road for the EPA.
JONATHAN ADLER: It's really not a significant constraint on the regulation of greenhouse gases going forward.
TOTENBERG: Adler and appellate lawyer Erik Jaffe both filled briefs in the case siding with industry. And both were pleased that at least the court didn't buy the EPA's argument that it could tailor a statute to make it work. Here's Jaffe.
ERIK JAFFE: At the end of the day, this gets the EPA what it wanted in a more sensible way. So it really did in some sense help the agency out while denying them this crazy authority that they claimed because they couldn't figure out the right way to do it.
TOTENBERG: The regulations at issue in today's case involve permits for pollution at new and modify plants. The bigger polluters on a case-by-case basis are those plants that were built a decade or more ago and have not been updated to limit emissions of greenhouse gases. The EPA just weeks ago issued proposed regulations to limit emissions at those existing plants too. Those proposed regulations are under a different section of the Clean Air Act that gives the agency more flexibility. Nina Totenberg, NPR News, Washington.
