yet unusual Indo-Oriental delicacies. Fine dining in the attractive price range of Rs 300 ? to determine the exact toughness of regulation needed. Today Scalia said that approach made no sense "By EPA’s logic someone could decide whether it is ‘appropriate’ to buy a Ferrari without thinking about cost because he plans to think about cost later when deciding whether to upgrade the sound system" Scalia wrote "It is unreasonable to read an instruction to an administrative agency to determine whether ‘regulation is appropriate and necessary’ as an invitation to ignore cost" In a withering dissent Justice Elena Kagan criticized the "peculiarly blinkered way" the court approached the case "I agree with the majority—let there be no doubt about this—that EPA’s power plant regulation would be unreasonable if ‘[t]he Agency gave cost no thought at all’ But that is just not what happened here" She said that EPA took costs into account in multiple stages over more than a decade and knew it would analyze the costs again when it decided exactly what level of mercury limits were needed "The Agency acted well within its authority in declining to consider costs at the opening bell of the regulatory process given that it would do so in every round thereafter—and given that the emissions limits finally issued would depend crucially on those accountings" she wrote The rule’s opponents led by Michigan had joined 21 other states utilities and coal mining interests in arguing that the only relevant figures EPA could consider were the $4 million to $6 million in annual forgone future earnings for those who suffer IQ loss from mercury poisoning as children Using those benefit figures meant $2400 in costs for the utilities for every $1 in benefits for the public That ratio "is not reasonable imposes great expenses on consumers and threatens to put covered electric utilities out of business" the petitioners concluded in their argument against the rule What’s next Today’s decision means that EPA will now have to either produce a new cost-benefit analysis or write an entirely new mercury plan at the same time that the agency already has a full agenda because of its efforts to take action on climate change Many of the same states utilities and coal mining interests that fought the mercury pollution rules are also lined up to battle EPA’s pending regulations to limit carbon dioxide emissions from existing power plants due out in the coming weeks (The Supreme Court’s decision in fact appears to topple one of their arguments—at least for the time being West Virginia and several other states argued that EPA couldn’t regulate carbon dioxide emissions because the agency already regulates mercury emissions) In some sense EPA’s effort on greenhouse gases called the Clean Power Plan could render the mercury issue moot Some utilities argue they will be forced to shut coal plants down under the Clean Power Plan eliminating both carbon dioxide and mercury emissions In theory power plants also may be able to address their mercury problem with installation of advanced carbon emissions controls; in its regulatory impact analysis EPA lists reduction of mercury as a potential side benefit of proposed carbon dioxide rules But the greenhouse gas battle is just beginning and because it involves the same interests could rage as long as the fight over mercury which began in the mid-1990s In the meantime however mercury emissions likely will continue unabated at some 170 power plants accounting for about 40% of the US coal fleet On the one hand there’s good news in that statistic It means about 60% of US coal plants already have equipment that allows them to meet the tighter mercury standards called for by the now blocked rule Those plants were able to comply because they already had equipment to control acid rain emissions—flue gas desulfurization units—that could be adjusted to capture mercury as a side benefit the US Energy Information Administration (EIA) said in an analysis last year Of the remaining coal plants with uncontrolled mercury and air toxics emissions EIA said operators have already slated about 10% for retirement That would continue a trend that has been well underway; according to the Sierra Club which has been campaigning for shutdown of US coal plants 187 have been closed since 2011 when the Obama administration first proposed the mercury regulations Most analysts agree that the shuttering of coal plants has been caused by not only the mercury rules and other regulatory actions but because of competition from cheaper natural gas fuel Because natural gas doesn’t produce mercury emissions when burned the market’s shift to that fuel also has helped curb air toxics Technical challenges What today’s decision won’t resolve are the technical complexities of removing mercury waste from coal plant emissions The type of coal that a plant burns and the design of the facility can make a difference in how easily the mercury can be removed A sorbent like activated carbon can remove mercury but dried sorbent injection systems are more cost-effective in plants that burn low-sulfur coal For plants that burn high-sulfur coal the scrubber that removes sulfur dioxide to meet acid rain rules is effective at removing a large amount of mercury but not enough to meet the proposed EPA standard of 90% or higher removal Plant operators have to add an activated carbon injection system or other technology to boost the scrubber’s effectiveness "There’s no silver bullet—even for the same utility" said Corey Tyree director of energy and environment at the Southern Research Institute in Birmingham Alabama a nonprofit organization that works both for the utility industry and the US government "What utilities struggle with is they look at their coal plant and it already removes 80% of the mercury but they have to get it to 90% and there’s all this additional cost for a small uptick" Tyree says Many of the problems plants face are due to the fact that elemental mercury is insoluble Plant operators typically will turn to technology to oxidize the mercury or they will use a halogen like bromine to combine with the mercury so that it can be dissolved But they have to guard against mercury returning to elemental form and being re-emitted through the smokestack Also the mercury compounds and sorbents add to the costs of the plant handling its solid or liquid waste Tony Facchiano senior program manager of the environmental controls program area of the Electric Power Research Institute (EPRI) an industry-funded nonprofit organization in Washington DC, Justice Antonin Scalia,By: IANS | London | Updated: October 7 said a statement.
