The Colstrip coal plant in Montana, labeled the worst emitter of particulate pollution by the EPA, has requested a two-year exemption from new pollution standards set by the Biden administration. Local officials argue that closure of the facility could disrupt the energy grid, despite health experts warning of the severe public health impacts associated with its emissions.

Colstrip Coal Plant Seeks Pollution Waiver Amid Health Concerns
The most polluting coal power plant in the U.S. requests an exemption to air pollution rules while local leaders raise economic viability concerns.
The Colstrip coal plant in Montana, identified by the Environmental Protection Agency (EPA) as the leading source of harmful particulate matter pollution in the United States, has applied for a waiver from new air pollution regulations. This request comes following the Biden administration's introduction of stricter pollution standards aimed at reducing hazardous emissions.
Officials from Montana, including Senator Steve Daines, argue that the aging plant's closure would have dire implications for the energy grid and the local economy. In a letter to EPA Administrator Lee Zeldin, they expressed concern that implementing the new pollution standards could threaten the plant's economic viability and lead to rising energy costs for consumers.
The Colstrip facility is the only coal power plant in the country that lacks modern pollution controls, and the new regulations could compel it to adopt updated equipment. Nevertheless, health experts have raised alarms regarding the implications of the plant's emissions. Research indicates that fine particulate matter can penetrate deep into human lungs and bloodstream, leading to heightened risks of cardiovascular and respiratory diseases.
While local leaders emphasize the necessity of the plant for maintaining energy stability and stimulating regional economic development, the public health consequences of continued operation without updated pollution control measures remain largely unaddressed in their advocacy efforts. As the debate unfolds, the potential clash between economic interests and health considerations drives the ongoing conversation about the future of coal energy in America.
