Mercury pollution has devastating impacts on children and pregnant women, with 1 in 10 women in the US of childbearing age having potentially dangerous levels of mercury in their bodies. Coal-fired plants emit almost three quarters of all air emissions in the U.S. This mercury pollution become airborne and eventually ends up in waterways, contaminating fish. The Mercury and Air Toxic Standards created by EPA in 2011 was designed to address this environmental hazard and according to EPA's own projections, the mercury standard has saved upward of 17,000 lives per year. Despite this success, the EPA is proposing to modify MATS, making the standards weaker. EPA is taking public comments on their proposal to revise the Mercury and Air Toxics Standards.
