Due to new federal air pollution regulations, more than 32 power plants across the country will be forced to close their doors, according to a recent Associated Press survey. Those plants, which are mostly coal-fired, discharge enough electricity to supply more than 22 million households, the survey notes, and their closure will lead to job layoffs, depleted tax revenues, and a considerable hike in electric bills. The areas that will be hit hardest are the Midwest and in the coal belt (Virginia, West Virginia, and Kentucky), where dozens of plants will likely be retired. Two regulations are in question: One aims to curb air pollution in states downwind from pollutant-heavy power plants; and the second, which was finalized last week, would enact the first standards for mercury, acid gas, and other pollutants from plant smokestacks. In total, the new regulations could eliminate more than eight percent of coal-fired generation nationwide. AP’s survey, the first of its kind, looked at the analyses by the Environmental Protection Agency (EPA) of plant retirements and interviewed 55 power plant operators about the effects on power supply and about their plans to deal with the new regulations.
