The Senate Environment and Public Works Committee recently a hearing on the Mercury and Air Toxics Standard. EPA Assistant Administrator, Gina McCarthy, testified forcefully about the tremendous public health and environmental benefits of this standard, as well as the fact that it is affordable to achieve and will not threaten the reliability of our electric system. Senator Inhofe used the opportunity to launch yet another tirade against the EPA, utterly failing to acknowledge that coal-fired power plants are the largest source of airborne mercury, a potent neurotoxin known to cause harm to fetal brain development.
EPA Power Plant Standards: A Powerful Catalyst for Modernizing our Electric System
UCS has just released a background paper, EPA Power Plant Standards: A Powerful Catalyst for Modernizing our Electric System, that debunks the tired rhetoric of the fossil fuel industry and its allies in Congress aimed at delaying or rolling back these vital health protections.
The long-awaited Clean Air Act power plant standards will bring significant public health, environmental and economic benefits by lessening our dependence on coal. Harmful pollutants released by burning coal have been linked to an increase in asthma attacks, heart disease, neurological problems, and premature deaths. Carbon emissions from coal-fired power plants contribute significantly to the risks of climate change.
The Lights will stay on
Some have greatly exaggerated the potential reliability and economic concerns related to this positive transformation of our electric system. The reality is that coal-fired power has become increasingly uneconomic for a variety of reasons (including competition from cleaner, low cost alternatives like natural gas, renewable energy and efficiency). Over the next few years, many coal plants will be updated with modern pollution controls that will reduce their harmful emissions. Those that do retire can be replaced by a number of economically competitive, readily available alternatives. For the most part, the standards are expected to have minimal impact on reliability. Close coordination between electric reliability authorities and the use of well-defined processes and procedures to identify and respond to the isolated instances where reliability may be an issue.
However, additional policies that explicitly support the deployment of renewable energy and increased energy efficiency are needed, so that those resources can complement the role played by natural gas as part of a diversified and affordable clean energy resource base. Putting such policies in place will help ensure that the full benefit of this opportunity to modernize and clean up our electric system is realized.
Protecting Public Health and Strengthening our Economy
In her testimony today, Assistant Administrator McCarthy also quoted from the remarks of President Obama to EPA staff last January: “Safeguarding our environment is also about strengthening our economy. I do not buy the notion that we have to make a choice between having clean air and clean water and growing this economy in a robust way. I think that is a false debate.”
Keeping that in mind, it is time for the Administration to release new standards to curtail global warming emissions from power plants, the largest source of such emissions in our economy. The risks of climate change for our health are likely to be significant and they will only worsen if we fail to take prompt action to lower our emissions.
