Available in PDF, EPUB and Kindle. Book excerpt: Mercury is a hazardous air pollutant (HAP) that can pose a serious public health threat. In accordance with the authority provided by the Clean Air Act (CAA), the EPA is considering regulation of mercury emissions from electric steam generating units (electric utilities). Recently, the EPA proposed revising an earlier finding that regulation of such emissions was warranted under section 112 of the CAA, because the agency had failed to consider whether regulations promulgated under section 111 of the CAA would adequately address the health concerns associated with these emissions. The EPA now proposes regulation of electric utilities' mercury emissions under section 111 through the adoption of a national "cap-and-trade" program. A potential challenge to the EPA proposal could grow out of the statutory basis for regulating electric utilities' mercury emissions under section 111. If the EPA implements the proposed revision and rule, it may argue that its interpretation should be upheld given (1) the arguably conflicting amendments made to section 111 in 1990 and (2) the deference shown by the courts to agency interpretations. Opponents may argue that the EPA's interpretation is unreasonable because the conflicting amendments do not represent a clear reversal of the previously explicit congressional intent to ...

This book was released on 2005-04-01 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reviews EPA's development of its proposed rule for controlling mercury emissions (ME) from coal-fired electric utilities. Coal-fired electric utilities represent the largest source of airborne ME in the U.S. Once airborne, mercury can be deposited into water, where it bio-accumulates in fish & animals at the top of the food chain. Human consumption of fish is the primary method of exposure to mercury, which has been shown to cause neurological & fetal developmental problems. On Jan. 30, 2004, EPA proposed rules for regulating ME from coal-fired steam generating electric utility units. EPA proposed two options for controlling ME, one a control technology standard with emission limits & the other a performance based cap-&-trade approach.

Download or read book CHARACTERIZATION AND MODELING OF THE FORMS OF MERCURY FROM COAL-FIRED POWER PLANTS. written by and published by . This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1990 Clean Air Act Amendments (CAAAs) required the U.S. Environmental Protection Agency (EPA) to determine whether the presence of mercury in the stack emissions from fossil fuel-fired electric utility power plants poses an unacceptable public health risk. EPA's conclusions and recommendations were presented in the Mercury Study Report to Congress (1) and the Utility Air Toxics Report to Congress (1). The first report addressed both the human health and environmental effects of anthropogenic mercury emissions, while the second addressed the risk to public health posed by the emission of mercury and other hazardous air pollutants from steam-electric generating units. Given the current state of the art, these reports did not state that mercury controls on coal-fired electric power stations would be required. However, they did indicate that EPA views mercury as a potential threat to human health. In fact, in December 2000, the EPA issued an intent to regulate for mercury from coal-fired boilers. However, it is clear that additional research needs to be done in order to develop economical and effective mercury control strategies. To accomplish this objective, it is necessary to understand mercury behavior in coal-fired power plants. The markedly different chemical and physical properties of the different mercury forms generated during coal combustion appear to impact the effectiveness of various mercury control strategies. The original Characterization and Modeling of the Forms of Mercury from Coal-Fired Power Plants project had two tasks. The first was to collect enough data such that mercury speciation could be predicted based on relatively simple inputs such as coal analyses and plant configuration. The second was to field-validate the Ontario Hydro mercury speciation method (at the time, it had only been validated at the pilot-scale level). However, after sampling at two power plants (the Ontario Hydro method was validated at one of them), the EPA issued an information collection request (ICR). The ICR required all coal-fired utilities to submit the mercury concentrations in their coal for one year quarterly, and 80 coal-fired power plants were selected to do mercury flue gas analysis. It was decided by EPRI and the U.S. Department of Energy (DOE) that this project would be suspended until the results of the ICR were known. This report presents the results that were obtained at the two power plants referred to as Sites 111 and E-29. The EERC teamed with Radian International (now URS Corp.) to do the sampling and analysis at these two power plants.

Download or read book Emissions, Monitoring and Control of Mercury from Subbituminous Coal-Fired Power Plants written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Subbituminous Energy Coalition (SEC) identified a need to re-test stack gas emissions from power plants that burn subbituminous coal relative to compliance with the EPA mercury control regulations for coal-fired plants. In addition, the SEC has also identified the specialized monitoring needs associated with mercury continuous emissions monitors (CEM). The overall objectives of the program were to develop and demonstrate solutions for the unique emission characteristics found when burning subbituminous coals. The program was executed in two phases; Phase I of the project covered mercury emission testing programs at ten subbituminous coal-fired plants. Phase II compared the performance of continuous emission monitors for mercury at subbituminous coal-fired power plants and is reported separately. Western Research Institute and a number of SEC members have partnered with Eta Energy and Air Pollution Testing to assess the Phase I objective. Results of the mercury (Hg) source sampling at ten power plants burning subbituminous coal concluded Hg emissions measurements from Powder River Basin (PBR) coal-fired units showed large variations during both ICR and SEC testing. Mercury captures across the Air Pollution Control Devices (APCDs) present much more reliable numbers (i.e., the mercury captures across the APCDs are positive numbers as one would expect compared to negative removal across the APCDs for the ICR data). Three of the seven units tested in the SEC study had previously shown negative removals in the ICR testing. The average emission rate is 6.08 lb/TBtu for seven ICR units compared to 5.18 lb/TBtu for ten units in the SEC testing. Out of the ten (10) SEC units, Nelson Dewey Unit 1, burned a subbituminous coal and petcoke blend thus lowering the total emission rate by generating less elemental mercury. The major difference between the ICR and SEC data is in the APCD performance and the mercury closure around the APCD. The average mercury removal values across the APCDs are 2.1% and 39.4% with standard deviations (STDs) of 1990 and 75%, respectively for the ICR and SEC tests. This clearly demonstrates that variability is an issue irrespective of using 'similar' fuels at the plants and the same source sampling team measuring the species. The study also concluded that elemental mercury is the main Hg specie that needs to be controlled. 2004 technologies such as activated carbon injection (ACI) may capture up to 60% with double digit lb/MMacf addition of sorbent. PRB coal-fired units have an Hg input of 7-15 lb/TBtu; hence, these units must operate at over 60% mercury efficiency in order to bring the emission level below 5.8 lb/TBtu. This was non-achievable with the best technology available as of 2004. Other key findings include: (1) Conventional particulate collectors, such as Cold-side Electro-Static Precipitators (CESPs), Hot-side Electro-Static Precipitator (HESP), and Fabric Filter (FF) remove nearly all of the particulate bound mercury; (2) CESPs perform better highlighting the flue gas temperature effect on the mercury removal. Impact of speciation with flue gas cooling is apparent; (3) SDA's do not help in enhancing adsorption of mercury vapor species; and (4) Due to consistently low chlorine values in fuels, it was not possible to analyze the impact of chlorine. In summary, it is difficult to predict the speciation at two plants that burn the same fuel. Non-fuel issues, such as flue gas cooling, impact the speciation and consequently mercury capture potential.

Available in PDF, EPUB and Kindle. Book excerpt: On February 8, 2008, the D.C. Circuit decided New Jersey v. EPA, unanimously vacating two EPA rules under the Clean Air Act (CAA) regarding emissions of mercury from electric utility steam generating units (EGUs). The two rules had the effect of shifting EPA regulation of power-plant emissions of mercury from the more stringent and less flexible regime under CAA section 112, governing hazardous air pollutants (HAPs), to the less stringent and more flexible one under CAA section 111, authorizing national emission standards for new stationary sources. The court decision, unless reversed or circumvented by EPA's properly removing EGUs from section 112, will mean that each individual EGU will have to meet strict Maximum Achievable Control Technology standards, and that no cap-and-trade program will be authorized. Setting such standards might take time, however, as EPA gathers information on current emission levels and the effectiveness of control technologies, delaying the effective date of national mercury emission standards for EGUs to as late as 2014, according to knowledgeable observers. Legislation has been introduced in both the House and Senate to speed this process (S. 2643 and H.R. 1087). On February 8, 2008, the U.S. Court of Appeals for the D.C. Circuit rendered its decision in New Jersey v. EPA,1 unanimously vacating two EPA rules under the Clean Air Act (CAA) regarding emissions of mercury from electric utility steam generating units (EGUs). The case attracted widespread participation -- it was actually 29 consolidated petitions for review filed by, among others, 17 states. Seven other states joined EPA in defending the rules.
