Mercury pollution — the slippery slope

In a giant favor to the coal industry, the Trump administration is poised to undermine the Mercury and Air Toxic Standards (MATS) that control mercury and other toxic air pollution from coal-fired power plants. 

Mercury is a potent neurotoxin that damages the brain of developing fetuses, increases the likelihood of heart attacks and causes serious harm to the nervous, reproductive, renal and immune systems. 

These facts have not stopped the Environmental Protection Agency (EPA) from proposing to revoke its previous finding that is “appropriate and necessary” to curb releases of mercury, arsenic and other hazardous air pollutants from coal- and oil-fired power plants.

Ironically, the power industry is in compliance with MATS, which was issued by the Obama administration in 2012. Toxic emissions from power plants have fallen by more than 90 percent at a fraction of the cost originally estimated by EPA.

Almost no one wants this regulation rescinded. The electric power industry has actually asked EPA to leave MATS in place. It has installed the necessary equipment and is operating in compliance with the rule. Utility commissions have allowed most power companies to recoup their costs based on MATS compliance. The environmental, medical and public health communities, as well as environmental justice organizations that represent mostly low-income communities and people of color who live near coal-fired power plants, strongly support MATS. 

There is one clear outlier. Bob Murray, founder and chairman of the bankrupt coal company, Murray Energy. Not only is he a Trump supporter and major donor to the Trump inauguration, but following President TrumpDonald TrumpTrump announces new tranche of endorsements DeSantis, Pence tied in 2024 Republican poll Lawmakers demand changes after National Guard troops at Capitol sickened from tainted food MORE’s inaugural ceremony, Murray sent a wish list of actions that he thinks will save coal; killing MATS is on it. 

But killing MATS will not save coal. Coal is failing because it is cheaper to generate electricity with natural gas and, increasingly, renewable energy. 

For now, MATS remains in place. But with this devious finding that it is not appropriate or necessary to control mercury and other air toxics from power plants, EPA Administrator Andrew WheelerAndrew WheelerEPA sued by environmental groups over Trump-era smog rule Environmental groups sue over federal permit for Virgin Islands refinery OVERNIGHT ENERGY: Court rules against fast-track of Trump EPA's 'secret science' rule | Bureau of Land Management exodus: Agency lost 87 percent of staff in Trump HQ relocation | GM commits to electric light duty fleet by 2035 MORE is inviting the coal industry to challenge the legitimacy of the rule. There are sound legal arguments to rebut such a challenge, but there is no guarantee that they will carry the day.

The Trump administration justifies this reckless action with a bogus economic analysis that purports to show that MATS costs more than its benefits are worth. To get that result, they inflate the cost of MATS and simply don’t count most of the benefits, including the direct benefits of controlling mercury and the indirect benefits of the reduced particulate pollution that results when mercury emissions are controlled.  

But the benefits of MATS are real, even if the EPA chooses not to count them. They include hundreds of lives saved each year, thousands of babies born annually without neurologic damage and the decrease of thousands of asthma attacks and respiratory illnesses that result in hospitalizations, lost work and school days each year.  

EPA is reversing a rule with benefits greater than its costs. It is corrupt and cruel to put people at risk for no good reason but to appease the coal industry and its champions.
