* States will decide how to cut emissions
* Changes to cut health care costs by up to $9 bln/yr-EPA
* Opponents say new rules would be costly to implement (Adds details, EPA comment)

WASHINGTON, Dec 14 (Reuters) - The Obama administration on Friday tightened limits on harmful soot pollution from sources including power plants, diesel engines and burning wood.
The new standards, which the Environmental Protection Agency was under court order to finalize, limit annual average soot emissions by the end of decade to about 12 micrograms per cubic meter of air from the standard of 15 micrograms set in 1997.
Individual states will be responsible for deciding how to cut emissions of the fine particulates, which can lodge deep in the lungs and threaten the elderly, people with heart disease and children. Health problems associated with the pollution include premature death, acute bronchitis, and asthma.
“More mothers like me will be able to rest a little easier knowing that our children and our children’s children will have healthier air to breathe for decades to come,” EPA Administrator Lisa Jackson, who has two sons with asthma, told reporters in a conference call about the rules.
Industry groups and some lawmakers have complained the soot standards are too costly. The standards “impose significant new economic burdens on many communities, hurting workers and their families,” a group of senators including global warming skeptic Jim Inhofe, an Oklahoma Republican, and Mary Landrieu, a Louisiana Democrat, said in a letter on Friday to Jackson.
New power plants, machinery at ports and other industrial sources of soot could find it hard to get operating permits in places found in violation of the limits.
The American Petroleum Institute, an industry group, said it feared the new rule “may be just the beginning of a ‘regulatory cliff’” including forthcoming EPA rules on smog and greenhouse gas emissions.
“EXCITING AND ENERGIZING”
The EPA, however, estimated that by 2030 the soot rules would prevent up to 40,000 premature deaths and that health care bills would be cut by $4 billion to $9 billion annually. Costs on industry to implement the rules would range from $53 million to $350 million, it said.
The agency said only seven counties, all of them in central or southern California, are projected to fail to meet the standard by 2020. The rest of the counties can rely on air quality standards that have already been finalized to meet the limits, it said.
Many observers have speculated Jackson could step down from the EPA next year, after four years fighting Republicans in Congress. She did not comment on the speculation on the call, saying only there was still plenty to do at the EPA, work that is “exciting and energizing.”
Her agency is expected to roll out more pollution rules on power plants, refineries and boilers that were delayed during the election year.
Environmentalists and health groups applauded the soot rules, which federal clean air laws require to be reviewed every five years.
Carol Browner, who served as EPA administrator from 1993 to 2001, said American innovation has found ways to meet pollution standards while contributing to new technology and jobs.
“We don’t have to choose between a healthy economy and healthy air and lungs,” she said. “We can have both.” (Reporting by Timothy Gardner; Editing by Gerald E. McCormick and Bob Burgdorfer)
