WASHINGTON Risking an election-year backlash from Republicans, the Obama administration is proposing new air quality standards to lower the amount of soot that can be released into the air.
The move by the Environmental Protection Agency won immediate support from environmental groups and public health advocates, who said the EPA was protecting millions of Americans at risk of asthma attacks, lung cancer, heart disease and premature death.
But congressional Republicans and industry officials called the rules overly strict and said they could hurt economic growth and cause job losses in areas where pollution levels are determined to be too high.
EPAs proposal could substantially increase costs to states, municipalities, businesses and ultimately consumers without justified benefits, said Howard Feldman, director of regulatory and scientific affairs for the American Petroleum Institute, the top lobbying group for the oil and gas industry.
Feldman said the rule could discourage economic investment in counties that fail to meet new federal standards, including in political swing states such as Ohio and Pennsylvania, where a natural gas drilling boom has boosted the local economies.
Non-attainment means non-investment by industry, Feldman said.
Perhaps wary of the rules political risk, the administration had sought to delay the new soot standards until after the November elections. But a federal judge ordered officials to act after 11 states filed a lawsuit seeking a decision this year by the Environmental Protection Agency.
An administration official said the new rule was based on a rigorous scientific review. Virtually all counties in the United States would meet the proposed standard by 2020 with no additional actions needed beyond compliance with current and impending rules set by the EPA, the official said.
Soot, made up of microscopic particles released from smokestacks, diesel trucks and buses, wood-burning stoves and other sources, contributes to haze and can burrow into lungs. Breathing in soot can cause lung and heart problems.
Dr. Albert Rizzo, chairman of the board of the American Lung Association, said soot, also known as fine particle pollution, is a known killer.
The science is clear, and overwhelming evidence shows that particle pollution at levels currently labeled as officially `safe causes heart attacks, strokes and asthma attacks, he said.
Eleven states, including New York and California, filed suit earlier this year to force a decision. The states and the American Lung Association say current standards jeopardize public health. Soot has been linked to thousands of premature deaths each year, as well as aggravation of respiratory illnesses, heart attacks and strokes.
More than a dozen states, along with environmental groups, sued the EPA several years ago, contending that the Bush administration had ignored science and its own experts when it decided in 2006 not to lower the nearly decade-old annual standard for soot. The agencys own analysis found a lower standard recommended by scientific advisers would have prevented almost 2,000 premature deaths each year.
The EPA initially promised it would review recent science and issue a decision in 2011. After months of inaction, states led by New York filed suit to force a decision. The lung association and the National Parks Conservation Association filed a similar suit.
A federal court eventually ordered the EPA to propose a new rule by midnight Thursday. A final rule is due in December after a public comment period.
The new rule would set the maximum allowable standard for soot in a range of 12 to 13 micrograms per cubic meter of air. The current annual standard is 15 micrograms per cubic meter.
Administration officials said the proposed changes are consistent with advice from independent scientists and are based on extensive research showing negative health impacts from soot at lower levels than previously understood. The agency will solicit comments from the public, as well as industry, public health groups and other interested groups to help determine the final standard.
Besides California and New York, states joining in the lawsuit forcing an EPA decision were Connecticut, Delaware, Maryland, Massachusetts, New Mexico, Oregon, Rhode Island, Vermont and Washington.
