Available in PDF, EPUB and Kindle. Book excerpt: In March 2005, the EPA issued a rule that will limit mercury emissions (ME) -- a toxic element that causes neurological problems -- from coal-fired power plants, the nation's largest ind'l. source of ME. Under the rule, ME are to be reduced from a baseline of 48 tons/yr. to 38 tons in 2010 & to 15 tons in 2018. The ME target for 2010 is based on the level of ME achievable with technol. for controlling other pollutants -- which also capture some mercury -- because it believed emerging mercury controls had not been adequately demonstrated. This report: describes the use, availability, & effectiveness of technol. to reduce ME at power plants; & identifies the factors that influence the cost of these technol. & reports on available cost estimates.

This book was released on 2005 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: EPA studies conclude that at least 7.8% of American women have blood mercury levels sufficient to increase the risk of adverse health effects (especially lower IQs) in children they might bear. Thus, there was great interest in the agencys March 15, 2005, announcement that it was finalizing new regulations to control mercury (Hg) emissions from coal-fired electric power plants -- power plants account for 42% of total U.S. mercury emissions, according to EPA. In announcing the regulations, however, EPA stated that most mercury in the atmosphere comes from non-U.S. global sources. Thus, even if regulations could reduce power plant mercury emissions to zero, the agency concluded, there would be little change in the mercury health effects it has identified. Instead of more stringent requirements, EPA promulgated "cap-and-trade" standards that rely heavily on cobenefits from sulfur dioxide and nitrogen oxide controls installed under a separate agency rule, the Clean Air Interstate Rule (CAIR). This approach minimizes costs for electric utilities: by 2015, less than 1% of coal-fired power plants will have installed equipment specifically designed to control mercury, according to EPA. By 2020, only 4% of plants will have such equipment. Ten states have filed suit to overturn the agency s action, arguing that EPA is required by the Clean Air Act to impose more stringent Maximum Achievable Control Technology standards at each individual plant. Beginning in 2010, the cap-and-trade standards limit total power plant mercury emissions to 38 tons annually (a 21% reduction vs. 1999 levels). A second phase caps annual emissions at 15 tons, starting in 2018. According to the agency, trading and banking of emission allowances will result in lower than required emissions in the early years, but will delay achievement of the 15-ton cap to at least 2025. Thus, the net effect of the rule appears to be to postpone until the 2020s direct regulation of mercury (except as a co-benefit achieved from regulating other pollutants). EPA has sent contradictory signals regarding the importance of controlling mercury emissions. Its January 2004 analysis of the proposed rule estimated that the indirect benefits of more stringent regulations ($15 billion annually) would outweigh compliance costs by a factor of at least 16 to 1. Direct benefits (although unquantifiable) were said to be "large enough to justify substantial investment in Hg control." The analysis of the final rule, by contrast, concludes that quantifiable direct and indirect benefits of mercury control are just $43 million per year, with annual costs as high as $896 million. EPA s calculations did not include consideration of an academic study that it had funded, a factor contributing to the calculation of smaller benefits. This decision was one of several irregularities in the regulatory process alleged by the agency's Inspector General, GAO, and critics of the rule. In addition to EPAs regulatory effort, five bills that would regulate these emissions have been introduced so far in the 109th Congress, with more expected. S. 131, the Clear Skies Act, has many points in common with the EPA regulatory approach. This report will be updated.

Book excerpt: Managing the nation's air quality is a complex undertaking, involving tens of thousands of people in regulating thousands of pollution sources. The authors identify what has worked and what has not, and they offer wide-ranging recommendations for setting future priorities, making difficult choices, and increasing innovation. This new book explores how to better integrate scientific advances and new technologies into the air quality management system. The volume reviews the three-decade history of governmental efforts toward cleaner air, discussing how air quality standards are set and results measured, the design and implementation of control strategies, regulatory processes and procedures, special issues with mobile pollution sources, and more. The book looks at efforts to spur social and behavioral changes that affect air quality, the effectiveness of market-based instruments for air quality regulation, and many other aspects of the issue. Rich in technical detail, this book will be of interest to all those engaged in air quality management: scientists, engineers, industrial managers, law makers, regulators, health officials, clean-air advocates, and concerned citizens.
Download or read book Coal Fired Flue Gas Mercury Emission Controls written by Jiang Wu and published by Springer. This book was released on 2015-03-17 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury (Hg) is one of the most toxic heavy metals, harmful to both the environment and human health. Hg is released into the atmosphere from natural and anthropogenic sources and its emission control has caused much concern. This book introduces readers to Hg pollution from natural and anthropogenic sources and systematically describes coal-fired flue gas mercury emission control in industry, especially from coal-fired power stations. Mercury emission control theory and experimental research are demonstrated, including how elemental mercury is oxidized into oxidized mercury and the effect of flue gas contents on the mercury speciation transformation process. Mercury emission control methods, such as existing APCDs (air pollution control devices) at power stations, sorbent injection, additives in coal combustion and photo-catalytic methods are introduced in detail. Lab-scale, pilot-scale and full-scale experimental studies of sorbent injection conducted by the authors are presented systematically, helping researchers and engineers to understand how this approach reduces the mercury emissions in flue gas and to apply the methods in mercury emission control at coal-fired power stations. Readers will arrive at a comprehensive understanding of various mercury emission control methods that are suitable for industrial applications. The book is intended for scientists, researchers, engineers and graduate students in the fields of energy science and technology, environmental science and technology and chemical engineering.

Book excerpt: On December 15, 2003, the Environmental Protection Agency (EPA) proposed standards for emissions of mercury from coal-fired electric power plants, under the authority of Sections 111 and 112 of the Clean Air Act. (The proposal appeared in the Federal Register January 30, 2004.) In their first phase, the standards could require a 29% reduction in emissions by 2008 or 2010, depending on the regulatory option chosen. A nearly 70% reduction would take effect in 2018, although EPA indicates that flexibility built into the proposed standards could delay the full 70% reduction to as late as 2030. EPA's analysis of the proposed rule indicates that its benefits would outweigh the compliance costs by a factor of at least 16 to 1, leading many critics of the proposal to ask why the regulations should not be more stringent, or implemented more quickly. The Agency's official position is that technology will not be available to achieve reductions greater than 30% until after 2010. EPA's own Office of Research and Development (ORD) appears to disagree, however. A recent ORD white paper found that reductions of 72% - 98%, depending on coal type, are already being achieved at some plants using current technology. Other issues likely to be raised in the public comment period, which extends until June 29, include the impacts on eastern coal production and the effect of the proposals on mercury "hot spots." In addition to EPA's regulatory effort, in the current Congress nine bills have been introduced to regulate these emissions. An Administration bill, the "Clear Skies Act," has many points in common with the EPA regulatory proposal. The other bills before Congress are generally more stringent than the Administration's approach. These regulatory and legislative proposals reflect increasing concern over the potential health effects of mercury emissions. Mercury is a potent neurotoxin that can affect human health at very low concentrations. EPA considers children born to women with umbilical cord blood-mercury concentrations above 5.8 parts per billion to be at increased risk for adverse health effects, such as delayed development, neurological defects, and mental retardation. Recent EPA studies conclude that at least 7.8% (and possibly as many as 15.7%) of American women of child-bearing age have blood mercury levels above this threshold. U.S. air emissions of mercury come from eight principal sources. Of these, the largest source, and the last major source for which emission standards have been proposed, is coal-fired electric power plants. Coal-fired power plants account for between one-third and one-half of total U.S. mercury emissions. This report provides background on mercury and reviews regulatory and legislative proposals to reduce emissions of mercury to the air. CRS Report RL32203 and CRS Report RL31908 discuss legal issues raised by EPA's proposed rules and mercury in products and waste, respectively. This report will be updated as warranted.

Book excerpt: The most abundant energy source in our world is coal. Coal-fired power generation comes with significant costs to environment and human health. The water runoff from coal washeries carries pollution loads of heavy metals that contaminate ground water, rivers, and lakes e thus affecting aquatic flora and fauna. Fly-ash residue and pollutants contaminate soil and are especially harmful to agricultural activities. Most importantly for human health, combustion of coal releases emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter (PM), carbon monoxide (CO), volatile organic compounds (VOCs), and various trace metals like mercury, into the air through stacks that can disperse this pollution over large areas. All educated people in the world are worried about the environmental problems caused by coal based power plants. The burning of coal adds mainly to increase acid rain and hence increase air pollution which in turn is a cause of global warming, harm to flora and fauna and damage of property. Environmental regulations for coal-fired power plants in the world cover a comprehensive range of very tedious requirements. New regulations were implemented from 2014 in China, USA and European Union which fixed the `emission limits¿ very low for SO2 , NOx, mercury particulate for coal-fired power generation plants. Now it is the time to evaluate emission control technologies whether the technologies can be helpful in achieving the new lower emission limits. Coal-fired Electricity and Emissions Control covers innovative trends and reviews dealing emissions of carbon dioxide (CO2), sulfur dioxide (SO2), and nitric oxide (NO) from thermal power plants and its control strategy. The analysis shows that aggressive pollution control regulations such as mandating flue gas desulfurization, introduction and tightening of emission standards for all criteria pollutants, and updating procedures for environment impact assessments, are imperative for regional clean air and to reduce health impacts. It presents insights into the coal fired power plants using modern technologies pollute less than firstborn designs due to these new technologies that filter the flue gases in stacks; however various pollutants are still being emitted in several times higher amounts than natural gas based and other power plants.
