Obama carbon rule gives states more time to comply

WASHINGTON (AP) -- In a sweeping initiative to curb pollutants blamed for global warming, the Obama administration unveiled a plan Monday that cuts carbon dioxide emissions from power plants by nearly a third over the next 15 years, but pushes the deadline for some states to comply until long after President Barack Obama leaves office.

The 645-page rule, expected to be finalized next year, is a centerpiece of Obama's plans to tackle climate change and aims to give the United States more leverage to prod other countries to act when negotiations on a new international treaty resume next year. Under the plan, carbon emissions would be reduced 30 percent by 2030, compared to 2005 levels, putting in motion one of the most significant U.S. actions on global warming.

The proposal sets off a complex regulatory process, steeped in politics, in which the 50 states will each determine how to meet customized targets set by the Environmental Protection Agency, then submit those plans for approval.

"The glue that holds this plan together — and the key to making it work — is that each state's goal is tailored to its own circumstances, and states have the flexibility to reach their goal in whatever works best for them," EPA Administrator Gina McCarthy said as she formally announced the proposal.

McCarthy characterized the proposal as "ambitious, but achievable."

Some states will be allowed to emit more and others less, leading to an overall, nationwide reduction of 30 percent.

Many states that rely heavily on coal will be spared from cutting a full 30 percent. West Virginia, for example, must cut 23 percent by 2030 compared to what the state was emitting in 2012. Ohio's target is 28 percent, while Kentucky and Wyoming will have to find ways to make an 18 percent and 19 percent cut.

On the other extreme, New York has a 44 percent target, EPA figures show. New York has already joined with other Northeast states to curb carbon dioxide from power plants, reducing the baseline figure from which cuts must be made. But states like New York can get credit for actions they've already taken, lest they be punished for taking early action on climate change.

Initially, Obama wanted each state to submit their plans by June 2016. But the draft proposal shows states could have until 2017 — and 2018, if they join with other states to tackle the problem.

That means even if the rules survive legal and other challenges, the dust won't likely settle on this transformation until well into the next administration, raising the possibility that political dynamics in either Congress or the White House could alter the rule's course.

Although Obama doesn't need a vote in Congress to approve his plans, opponents in Congress could attempt to block them, and some Republicans have already vowed to pursue that course. Scuttling the rules could be easier if Republicans take the Senate in November and then the White House in 2016.

Another potential flash point: The plan relies heavily on governors agreeing to develop plans to meet the federal standard. If Republican governors refuse to go along, as was the case with Obama's expansion of Medicaid, the EPA can create its own plan for a state. But the specifics of how EPA could force a state to comply with that plan remain murky.

S. William Becker, who heads the National Association of Clean Air Agencies, credited the rule for giving states more time to develop strategies and granting credit for previous steps to cut emissions.

"Still, the regulatory and resource challenges that lie ahead are daunting," Becker said.

Power plants are the largest U.S. source of greenhouse gases, accounting for about a third of the annual emissions. EPA data show power plants have already reduced carbon dioxide emissions by nearly 13 percent since 2005, meaning they are about halfway to meeting the administration's goal.

The EPA projected that carrying out the plan will cost up to $8.8 billion annually in 2030, but the actual costs will depend heavily on how states choose to reach their targets. The administration argued that any costs to comply are far outweighed by savings in health costs that the U.S. will realize thanks to reductions in other pollutants like soot and smog that will accompany a shift away from dirtier fuels.

Environmental groups hailed the proposal, praising both the climate effects and the public health benefits they said would follow. Former Vice President Al Gore, a prominent environmental advocate, called it "the most important step taken to combat the climate crisis in our country's history."

But energy advocates sounded the alarm, warning of economic drag. Senate Minority Leader Mitch McConnell, R-Ky., called the proposal "a dagger in the heart of the American middle class."

"If these rules are allowed to go into effect, the administration for all intents and purposes is creating America's next energy crisis," said Mike Duncan of the American Coalition for Clean Coal Electricity, which represents the coal industry.

Options for states to meet the targets include making power plants more efficient, reducing the frequency at which coal-fired power plants supply power to the grid, and investing in more renewable, low-carbon sources of energy. States could also enhance programs aimed at reducing demand by making households and businesses more energy-efficient. Each of those categories will have a separate target tailor-made for each state.

Coal once supplied about half the nation's electricity, but has dropped to 40 percent amid a boom in natural gas and renewable sources such as wind and solar. Although the new emissions cuts will further diminish coal's role, the EPA predicted that would still remain a leading source of electricity in the U.S., providing more than 30 percent of the projected supply.

Obama has already tackled the emissions from the nation's cars and trucks, announcing rules to reduce carbon dioxide emissions by doubling fuel economy. That standard will reduce carbon dioxide by more than 2 billion tons over the life of vehicles made in model years 2012-25. Calculations based on EPA figures show the proposal will prevent about 430 million tons of carbon dioxide from reaching the atmosphere.
