The weakening of mercury emission limits by the United States===United States Environmental Protection Agency is expected to reduce operating costs for coal-fired power plants, potentially boosting the coal industry and improving grid reliability. However, environmental groups warn of negative public health impacts, which could lead to future regulatory challenges or public backlash.
The United States===United States Environmental Protection Agency, under the Donald Trump administration, has weakened limits on mercury and other toxic emissions from coal-fired power plants. This move, announced at the Mill Creek Generating Station in Louisville, Kentucky, aims to support the fossil fuel industry by rolling back clean air and water rules. The new rule reverts to standards established in 2012 by the Barack Obama administration, which had reduced mercury emissions by nearly 90%. The Joe Biden administration had previously sought to tighten these standards further. Industry groups, such as America s Power and the National Rural Electric Cooperative Association, welcomed the decision, citing cost savings and improved grid reliability. Environmental groups, including America Is All In, and former United States===United States Environmental Protection Agency head Gina McCarthy, criticized the action, warning of adverse public health effects and increased pollution.
