EPA Administrator Lisa Jackson said, "These standards are fulfilling the promise of the Clean Air Act. We will save lives and reduce the burden of illness in our communities, and families across the country will benefit from the simple fact of being able to breathe cleaner air."
A release from EPA indicates that fine particle pollution can penetrate deep into the lungs and has been linked to a wide range of serious health effects, including premature death, heart attacks, and strokes, as well as acute bronchitis and aggravated asthma among children. A Federal court ruling required EPA to update the standard based on best available science. EPA said today's announcement, "meets that requirement, builds on smart steps already taken by EPA to slash dangerous pollution in communities across the country. Thanks to these steps, 99 percent of U.S. counties are projected to meet the standard without any additional action."
EPA indicated that it is expected that fewer than 10 counties, out of the more than 3,000 counties in the United States, will need to consider any local actions to reduce fine particle pollution in order to meet the new standard by 2020, as required by the Clean Air Act. The rest can rely on air quality improvements from Federal rules already on the books to meet this new standard. A map released by EPA indicates that "7 counties are projected not to meet 12.0 μg/m3 in 2020" -- all located in southern California.
The standard, which was proposed in June [See WIMS 6/18/12] and is consistent with the advice from the agency's independent science advisors, is based on an extensive body of scientific evidence that includes thousands of studies including many large studies which show negative health impacts at lower levels than previously understood. It also follows extensive consultation with stakeholders, including the public, health organizations, and industry, and after considering more than 230,000 public comments.
By 2030, it is expected that all standards that cut PM2.5 from diesel vehicles and equipment alone will prevent up to 40,000 premature deaths, 32,000 hospital admissions and 4.7 million days of work lost due to illness. Because reductions in fine particle pollution have direct health benefits including decreased mortality rates, fewer incidents of heart attacks, strokes, and childhood asthma, the PM2.5 standards announced have major economic benefits with comparatively low costs. EPA estimates health benefits of the revised standard to range from $4 billion to over $9 billion per year, with estimated costs of implementation ranging from $53 million to $350 million. While EPA cannot consider costs in selecting a standard under the Clean Air Act, those costs are estimated as part of the careful analysis undertaken for all significant regulations, as required by Executive Order 13563 issued by President Obama in January 2011.
The Clean Air Act requires EPA to review its air quality standards every five years to determine whether the standards should be revised. The law requires the agency to ensure the standards are "requisite to protect public health with an adequate margin of safety" and "requisite to protect the public welfare." A Federal court required EPA to issue final standard by December 14, because the agency did not meet its five-year legal deadline for reviewing the standards.
