Book Research Priorities for Airborne Particulate Matter

Download or read book Research Priorities for Airborne Particulate Matter written by National Research Council and published by National Academies Press. This book was released on 2004-10-22 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, the U.S. Environmental Protection Agency (EPA) established regulatory standards to address health risks posed by inhaling tiny particles from smoke, vehicle exhaust, and other sources. At the same time, Congress and the EPA began a multimillion dollar research effort to better understand the sources of these airborne particles, the levels of exposure to people, and the ways that these particles cause disease. To provide independent guidance to the EPA, Congress asked the National Research Council to study the relevant issues. The result was a series of four reports on the particulate-matter research program. The first two books offered a conceptual framework for a national research program, identified the 10 most critical research needs, and described the recommended timing and estimated costs of such research. The third volume began the task of assessing initial progress made in implementing the research program. This, the fourth and final volume, gauged research progress made over a 5-year period on each of the 10 research topics. The National Research Council concludes that particulate matter research has led to a better understanding of the health effects caused by tiny airborne particles. However, the EPA, in concert with other agencies, should continue research to reduce further uncertainties and inform long-term decisions.

Book Particulate Matter Air Quality Standards

Download or read book Particulate Matter Air Quality Standards written by and published by . This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Environmental Protection Agency (EPA) is nearing completion of its review of contentious air quality standards for particulate matter (PM), with final action expected in late 2005. The current standards are among the most far-reaching regulations on EPA's agenda. Promulgated in 1997, but only now being implemented, the standards could potentially prevent the loss of thousands of lives annually at an annual cost estimated by the agency to be $8.6 billion. The Clean Air Act (CAA, Sections 108 and 109) requires that air quality criteria used in determining National Ambient Air Quality Standards (NAAQS) reflect the latest scientific information. The act includes provisions for the periodic review and revision, as appropriate, of existing criteria and standards. It is this periodic review process that is nearing completion. In October 2004, EPA released Air Quality Criteria for Particulate Matter, reflecting the agency's synthesis of relevant PM research conducted since the agency's last review, completed in 1996. This report, referred to as a "criteria document," will provide the scientific basis for assessments and policy decisions regarding the adequacy of the current PM NAAQS. Further decisions, including recommendations regarding the standards, are expected early in 2005, following the release of what is referred to as a "staff paper." Meanwhile, EPA is continuing implementation of the 1997 particulate matter standards, which had been delayed several years by litigation and other factors. On January 5, 2005, EPA published the final designations of geographical areas for the fine particulate matter or "PM2.5" (particles less than 2.5 micrometers in diameter) NAAQS. EPA designated 225 counties in 20 states, and the District of Columbia, as "nonattainment areas"; those areas with (or contributing to) air quality levels exceeding the annual and 24-hour PM2.5 standards. Congress and a wide variety of stakeholders have closely followed the evolution and development of PM NAAQS. In 1997, when the current standards were promulgated, Congress held 28 days of hearings on the EPA rule. Subsequently, more than 100 plaintiffs sued to overturn the standards. This litigation went to the Supreme Court before being resolved, largely in EPA's favor, in February 2001. Since FY1998, in an effort to expedite research and strengthen the science underlying EPA's review of the standards, Congress has appropriated funding specifically for PM research annually ($62 million for FY2005). The research, including re-analysis of key studies underlying the 1997 standards, has largely confirmed EPA's earlier conclusions, although new questions have been raised regarding the methodology used in some of the studies. The National Academy of Sciences (NAS) has issued four reports on the state of PM research at EPA, and EPA released a report reviewing its five-year progress of PM research. Because of the potential impacts particulate matter standards could have on both public health and the economy, EPA's reassessment of the PM standards will likely be of continued interest to Congress. This report will be updated as events warrant.

Download or read book Research Priorities for Airborne Particulate Matter written by National Research Council and published by National Academies Press. This book was released on 2001-07-13 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regulatory standards are already on the books at the the U.S. Environmental Protection Agency (EPA) to address health risks posed by inhaling tiny particles from smoke, vehicle exhaust, and other sources. At the same time, Congress and EPA have initiated a multimillion dollar research effort to better understand the sources of these airborne particles, the levels of exposure to people, and the ways that these particles cause damage. To provide independent guidance to the EPA, Congress asked the National Research Council to study the relevant issues. The result is a series of four reports on the particulate-matter research program. The first two books offered a conceptual framework for a national research program, identified the 10 most critical research needs, and described the recommended timing and estimated costs of such research. This, the third volume, begins the task of assessing the progress made in implementing the research program. The National Research Council ultimately concludes that the ongoing program is appropriately addressing many of the key uncertainties. However, it also identifies a number of critical specific subjects that should be given greater attention. Research Priorities for Airborne Particulate Matter focuses on the most current and planned research projects with an eye toward the fourth and final report, which will contain an updated assessment.

Book Research Priorities for Airborne Particulate Matter

Download or read book Research Priorities for Airborne Particulate Matter written by National Research Council and published by National Academies Press. This book was released on 1999-09-01 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the effort to reduce the scientific and technical uncertainties over regulation of airborne particulate matter in the United States, Research Priorities for Airborne Particulate Matter: II. Evaluating Research Progress and Updating the Portfolio, the second book in a four-part series requested by Congress, describes the plans of the committee to monitor the progress of the research on particulate matter conducted by the U.S. Environmental Protection Agency (EPA), other federal and state government agencies, and nongovernmental organizations. The book also reviews and updates the committee's portfolio of recommended research in its first volume, Research Priorities for Airborne Particulate Matter: I. Immediate Priorities and a Long-Range Research Portfolio (NRC, 1998). The committee substantially revised two of the ten high-priority research areas recommended in Part I. Part II notes that Congress, EPA, and the scientific community have given strong support to the committee's recommendations and have implemented substantial changes in research efforts in response to Part I of the series. One important research area-studies of the effects of long-term exposure to particulate matter and other major air pollutants-however, does not appear to be underway or planned.
