Reduce air pollution by suspending coal mining operations
Coal mining has extensive environmental impacts, from devastated landscapes to polluted waterways, and far-reaching effects on wildlife and human health. The production and consumption of coal generate air pollution in several ways. Firstly, wind erosion of exposed coal and mining waste (known as gangue) creates dust that is carried by the wind. Secondly, the oxidation of coal and gangue causes the formation of pollutants. Thirdly, the physical processes of handling coal, such as crushing it and loading it onto trucks, also generate pollution.
Suspending coal mining operations has been shown to reduce local air pollution by around 8%. This is supported by satellite-based air pollution data, which shows that suspending coal mining leads to improved ambient air quality. The reduction in air pollution has a direct impact on respiratory mortality, particularly in vulnerable populations. This is especially relevant given that air pollution contributed to 4.2 million deaths worldwide in 2020, with 80% attributed to human-induced emissions and 35% directly linked to the burning of fossil fuels.
In addition to suspending coal mining operations, there are other measures that can be taken to reduce air pollution from coal mining. One approach is to implement stricter safety regulations and enforce them through regular inspections. This includes requiring coal mining operators to obtain permits for discharging pollutants into rivers, streams, and other surface waters, as outlined by the National Pollutent Discharge Elimination System (NPDES) Permitting Program in the United States.
Furthermore, the coal industry can work with governments to develop and implement technologies that remove impurities from coal and improve energy efficiency, reducing the amount of coal burned. Power plants can also continue to adopt flue gas desulfurization equipment, or "scrubbers," to clean sulfur and other pollutants from smoke before it leaves the smokestack.
While suspending coal mining operations can effectively reduce air pollution, it is important to recognize that coal mining has other significant environmental impacts, particularly on water sources. Coal mining often results in water contamination, with highly acidic water containing heavy metals such as arsenic, copper, and lead, known as acid mine drainage. This has devastating effects on wildlife, with a recorded decline in fish populations and the presence of deformities in fish and birds. Therefore, addressing coal mining pollution requires a comprehensive approach that considers both air and water pollution, as well as the transition to renewable energy alternatives.

Reuse and recycle waste products from coal burning
Reusing and recycling waste products from coal burning can reduce the environmental effects of coal production and consumption. The process of burning coal at coal-fired power plants, called combustion, creates wastes that contain small amounts of naturally occurring radioactive material. Coal ash, fly ash, or coal combustion waste is a fine ash that results from capturing toxins in coal through modern air pollution controls and filtration systems. While coal ash contains toxic heavy metals, it can be reused in several applications, such as:
- Concrete and cement production: More than a third of coal ash produced in the United States is reused in concrete, often as a blend with cement.
- Construction: Coal ash can be used as fill in structures or embankments, as blasting grit, or as roofing granules.
- Wallboard material: Waste products captured by scrubbers can be used to produce synthetic gypsum for wallboards.
However, the reuse and recycling of coal waste are controversial. The EPA halted a program in 2010 that promoted beneficial uses of coal ash. The designation of coal ash as hazardous waste is debated, as it would increase disposal costs for the industry and potentially hinder recycling efforts. Nevertheless, the American Coal Ash Association (ACAA) has argued that tougher federal regulations are necessary to address the toxic nature of coal ash and protect the "beneficial-use industry."

Implement clean energy technologies
The transition to renewable energy sources is essential to mitigate the environmental and wildlife harms caused by coal mining. Clean energy technologies, such as wind, solar, and hydropower, can significantly reduce the climate-warming carbon dioxide (CO2) emissions associated with burning fossil fuels.
The Union of Concerned Scientists has long advocated for the adoption of clean energy technologies, recognizing the devastating impacts of coal mining on our lands, waters, and wildlife. Mountaintop removal, a highly destructive form of surface coal mining, has led to the burial of over 2,000 miles of headwater streams, causing irreversible losses in wildlife habitats, clean water sources, and natural benefits such as nutrient regulation and flood control.
Water contamination from coal mining has had devastating effects on aquatic life, with scientists observing a decline in species diversity and an increase in deformities in fish and birds. Additionally, coal mining contributes to air pollution, releasing sulfur dioxide, nitrogen oxides, particulates, and heavy metals that harm both human health and the environment.
To address these issues, we must support policies and initiatives that prioritize renewable energy alternatives. The volume of fossil fuels extracted today far exceeds the projected amount of minerals needed for clean energy technology by 2040, demonstrating the potential for a significant reduction in environmental impacts. While there are challenges in developing and implementing clean energy technologies, the urgent threat of climate change necessitates a transition to cleaner, more sustainable energy sources.
Clean coal technologies, such as carbon capture and sequestration, aim to reduce atmospheric carbon dioxide levels. While these technologies show promise, they also face challenges in terms of cost and energy efficiency. Nevertheless, continued research and development in this field are crucial to achieving "zero emissions" goals and ensuring a sustainable future for generations to come.

Support renewable energy policies and initiatives
The transition to renewable energy sources is essential to mitigate the environmental and public health impacts of coal mining and reduce the extensive ecological damage caused by this industry. Supporting renewable energy policies and initiatives is a crucial step towards phasing out coal and other fossil fuels. Here are some key strategies and considerations:
Policy Support for Renewable Energy Sources
Governments and policymakers play a pivotal role in promoting renewable energy alternatives. This includes providing incentives, subsidies, and regulations that encourage the adoption of renewable energy technologies such as wind, solar, and hydropower. These policies can foster investment in renewable energy infrastructure and research, accelerating the transition away from coal.
Energy Storage Solutions
The development and deployment of energy storage technologies are vital to the success of renewable energy sources. Energy storage allows us to capture and store excess energy for use during periods of lower generation, ensuring a stable and reliable energy supply. This is particularly important for intermittent renewable sources like solar and wind power. Governments and industries should prioritize investment in energy storage research and infrastructure to support the integration of renewables into the energy grid.
Community Engagement and Worker Support
The transition to renewable energy must also consider the social and economic impacts on coal-dependent communities and workers. Governments should facilitate early dialogue with affected stakeholders and implement social safety nets, retraining programs, and job relocation initiatives for coal power plant workers. By ensuring a just transition, communities can embrace renewable energy sources without bearing the brunt of economic hardship.
International Cooperation and Leadership
Given the global nature of the energy industry and climate change, international cooperation is essential. Countries that have historically relied heavily on coal, such as China and India, are making significant strides toward renewable energy. For example, China's massive expansion of renewables has contributed to a levelling off of coal consumption. International agreements, such as the 2015 Paris Agreement, provide a framework for countries to collaborate and accelerate the transition to renewable energy on a global scale.
Environmental Impact of Clean Energy Metals
While renewable energy sources are crucial for mitigating coal mining pollution, it is important to acknowledge the potential environmental impacts of mining clean energy metals. The demand for copper, lithium, and other materials necessary for clean energy technology is projected to surge in the coming decades. This will likely result in more extensive mining operations, posing risks to communities and biodiversity. Therefore, policies and initiatives should also focus on sustainable mining practices and circular economy approaches to minimize the environmental footprint of clean energy metal extraction.
In conclusion, supporting renewable energy policies and initiatives is a critical strategy to address coal mining pollution. By transitioning to renewable sources, we can reduce the devastating ecological and public health impacts of coal mining while also fostering innovation, job creation, and global cooperation.

Enforce pollution discharge permits for coal mining companies
Coal mining has extensive environmental impacts, from devastated landscapes to polluted waterways and air pollution. The degradation of water quality through coal mining can persist for decades post-mining. The Clean Air Act and the Clean Water Act require industries, including coal mining companies, to reduce pollutants released into the air and water.
To enforce pollution discharge permits for coal mining companies, the National Pollutant Discharge Elimination System (NPDES) Permitting Program requires that coal mining operators receive permits to discharge pollutants into rivers, streams, and other surface waters. The EPA has granted 46 states, including all states in Appalachia, the authority to issue and enforce NPDES permits. The EPA provides oversight and technical assistance to these states through its Regional offices.
NPDES permits for mining operations incorporate effluent guidelines, which are national regulations that set effluent standards for wastewater discharges. These guidelines cover wastewater discharges from mine drainage, coal storage facilities, and coal preparation plants. The Coal Mining Effluent Guidelines and Standards were first promulgated by the EPA in 1975 and have since been amended several times.
The EPA has taken enforcement action against coal mining companies that violate NPDES permits, such as in the case of Southern Coal Corporation and its affiliates, which were required to upgrade their operations to prevent discharges of polluted wastewater. The EPA has also conducted reviews of wastewater discharges from coal mines to inform possible revisions to existing Effluent Guidelines regulations.
By enforcing NPDES permits and ensuring coal mining companies comply with effluent guidelines, the discharge of pollutants into waterways can be reduced, helping to mitigate the environmental impacts of coal mining.

Frequently asked questions
Coal mining has been linked to air pollution, climate change, and the degradation of water and land. It also contributes to the emission of toxic and carcinogenic substances, which can lead to health issues such as asthma, heart and lung disease, and cancer.
The Clean Air Act and The Clean Water Act require industries to reduce pollutants released into the air and water. Reusing and recycling waste from coal burning can also help. Additionally, supporting policies and initiatives that prioritize renewable energy alternatives can help to mitigate the harms caused by coal mining.
Coal mining can contaminate nearby water sources through a process called acid mine drainage. This occurs when certain substances, such as iron sulfide, are oxidized after being exposed to air and water, leading to highly acidic water containing heavy metals. Coal ash produced by coal-fired power plants can also escape into nearby waterways, contaminating drinking water.
Mountaintop removal coal mining, a highly destructive process, has impacted large areas of the Appalachian Mountains in West Virginia and Kentucky. This method involves removing the tops of mountains with explosives and dumping the excess rock and soil into adjacent river valleys, burying headwater streams and causing critical losses in wildlife habitat and clean water sources.
