Court Kicks CAIR Rules to the CurbA federal appeals court has struck down a key Environmental Protection Agency (EPA) program for reducing fine particulate and smog-causing emissions in the eastern half of the nation, saying the rules were riddled with “several fatal flaws,” including the agency’s failure to properly focus pollution cuts to prevent movement of air pollution from one state from worsening air quality in a downwind state.
EEI Leaders Say Promise of Carbon Capture and Storage “Overblown”In a sobering assessment of a key technology that’s expected to help keep the coal industry viable in the face of likely greenhouse gas caps, several electric utility executives have expressed deep concern that the promise of carbon capture and storage for coal-fired power plants has been “overblown” and “oversold.”
Environmentally Sound Handling of Deactivated SCR CatalystSelective catalytic reduction systems were introduced as a means of reducing the nitrogen oxide emissions of power generators in the 1980s. Since then, environmental issues have increased in importance, as has the value of an SCR reactor. Unfortunately, because this technology is still so new, not all users understand its full potential and proper maintenance techniques.
EPA Staff’s GHG Proposal Will Paralyze the U.S. EconomyThe Environmental Protection Agency (EPA) has announced that is it well on its way to regulating at least 85% of the energy used in America in the name of global warming (never mind the fact that temperatures have inexplicably not increased since at least 2001). If the proposal is enacted, any organization or person that emits more than miniscule amounts of CO2 will be required to obtain a permit, effectively bringing our economy to its knees in short order.
How to Measure Flyash LevelsMeasuring the level of flyash in your silos is not an easy task, in part because the flyash collected at one plant can be remarkably different from that collected at another plant, even if both fire the same coal. Such variability means that selecting the right instrument for your application is important.
Rules Designed to Be BrokenBy Dr. Robert Peltier, PE
The fallout from the Supreme Court’s April 2, 2007, decision (Massachusetts v. Duke Energy) in which the high court ruled that the EPA does have the right to regulate CO2 emissions as a pollutant under the Clean Air Act (CAA) continues. The court also ruled that the EPA has the authority to regulate carbon emissions from automobiles and other vehicles—and, by extension, power plants (my words, not the court’s).
