EPA to tighten national soot standards @washingtonpost

The Environmental Protection Agency will announce a proposal Friday to tighten the nation’s soot standards, a move that could help deliver major health benefits by the end of the decade but force some oil refiners, manufacturers and other operations to invest in pollution abatement upgrades.

Particle pollution measuring less than 2.5 micrometers in diameter, also known as fine particles or soot, is possibly the most deadly widespread air pollutant. Measuring one-thirtieth the width of a human hair, these particles come from activities ranging from wood burning to vehicle emissions and can cause respiratory and heart ailments by entering the lungs and bloodstream.

Facing a court-ordered deadline, the EPA will propose tightening the annual exposure to fine-particle soot from 15 micrograms per cubic meter of air to between 12 and 13 micrograms per cubic meter of air, according to individuals who had been briefed on the rule making. Industry officials and environmentalists said the proposal, which will be finalized by mid-December, would have far-reaching implications for both the U.S. economy and public health.

“It’s going to be a big step forward,” said Frank O’Donnell, who heads the advocacy group Clean Air Watch. “This could help frame the national effort to clean this up for at least a decade.”

Jeffrey R. Holstead, former head of the EPA’s air and radiation office under President George W. Bush, said he’s been “a little surprised” that industry hasn’t launched as hard a fight against these rules as it did against an EPA smog proposal last year, which President Obama pulled back in September.

Administration officials declined to comment on the proposal Thursday, noting that it had not been announced. But they have said repeatedly that several of the rules the EPA has either implemented or is in the process of finishing — including ones curbing mercury and air toxics, sulfur dioxide and nitrogen oxide from sources such as power plants, industrial boilers and cement plants — will help communities meet stricter soot requirements without additional costs.

The question of how to set an acceptable level of soot exposure has been the subject of political and legal wrangling for years. In 2006 the Bush administration rejected the advice of its Clean Air Scientific Advisory Committee to make the annual standard more stringent and kept it at 15 micrograms per cubic meter, although it strengthened the 24-hour standard from 65 to 35 micrograms. Thirteen states and several environmental groups challenged the 2006 standards in court, and in 2009 a federal appeals court ordered the EPA to rewrite the rule.

The EPA’s staff and the Clean Air Scientific Advisory Committee, an independent group of experts, concluded that there is enough scientific evidence to lower annual average soot exposure to between 11 and 13 micrograms per cubic meter.

On June 6 Judge Robert Wilkins of the U.S. District Court for the District of Columbia ordered the EPA to issue its proposed rule by June 14.

Holmstead said the agency would be rushing to finalize such an important rule within six months, by Dec. 14. “This is probably the most important single issue under the Clean Air Act, and yet this is yet another sweetheart deal between the EPA and their allies in the environmental community,” he said.

Once a rule is finalized, the EPA must determine how many counties across the country will be out of attainment with the new soot standards, and those communities must eventually cut down on pollution or risk losing federal funds. Howard Feldman, director of regulatory and scientific affairs for the American Petroleum Institute, said a more-stringent rule will discourage economic investment in counties that fail to meet federal air quality standards.

“It’s in our interest to have a vibrant domestic economy,” Feldman said, adding that many companies eyeing a place to build a plant or refinery “perceive non-attainment to be non-investment.”

S. William Becker, executive director for the National Association of Clean Air Agencies, said “there is going to be a significant workload” for some counties to meet the new standard.

“That’s no reason not to support and follow the science, but it’s one reason EPA and Congress will need to step up and provide additional resources and set strong federal control measures,” Becker said.
