Senator Boxer said: "Power plants are not only the nation's largest source of dangerous mercury emissions, but they also pollute the air we breathe with lead, arsenic, chromium, and cyanide. These hazardous air pollutants are known to cause cancer, harm children's development, and damage the brain and nervous system of infants. EPA estimates that this new clean air rule will annually prevent up to 11,000 premature deaths, 4,700 heart attacks, 130,000 asthma attacks and many other health benefits. The science and methodology used to determine these benefits have been extensively peer reviewed by EPA's independent Science Advisory Board and the National Academies of Science. The agency estimates that this clean air rule will also provide up to 46,000 construction jobs and 8,000 long-term jobs in the utility industry. EPA's action today will generate jobs and protect the health and safety of families across the country."
