Ensure coal ash is stored in dry, lined storage away from rivers and other waterways
Coal ash is a toxic waste product generated from burning coal and is one of the largest industrial waste streams in the US. It contains contaminants like mercury, cadmium, and arsenic, which can pollute waterways, groundwater, drinking water, and the air if not properly managed.
To prevent coal ash pollution, it is crucial to ensure that coal ash is stored in dry, lined storage away from rivers and other water bodies. This is because coal ash ponds, often located along rivers and lakes, pose a significant risk of spills and contamination, threatening the health of nearby communities and the environment.
Storing coal ash in dry, lined storage facilities away from waterways is a critical step in preventing water pollution. Lined landfills act as a protective barrier, preventing toxic coal ash from leaching into the groundwater and nearby water bodies. This method of storage also reduces the risk of catastrophic spills that can occur when coal ash ponds fail due to floods or other extreme weather events.
Additionally, it is important to enforce regulations that prohibit the capping of coal ash waste ponds in floodplains. Capping in place does not effectively stop pollution, as groundwater can still come into contact with the coal ash, leading to contamination. By ensuring that coal ash is properly excavated and stored in lined landfills away from water sources, the risk of groundwater pollution and spills into rivers and lakes is significantly reduced.
Policymakers play a crucial role in this process by establishing regulations and guidelines for the storage and disposal of coal ash. This includes enforcing moratoriums on new or expanded coal ash ponds, prioritizing the closure of existing ponds that pose a threat to waterways, and ensuring that coal ash storage facilities are located away from rivers and other water sources.

Improve oversight to prevent toxic coal ash from entering water supplies
Coal ash, a toxic mix of carcinogens, neurotoxins, and other hazardous pollutants, is a dangerous byproduct of burning coal. It is one of the largest industrial waste streams in the United States, and its improper disposal has contaminated water supplies, causing serious health and environmental issues.
To prevent toxic coal ash from entering water supplies, improved oversight and stricter regulations are necessary. Here are some measures that can be implemented:
Firstly, enforce regulations prohibiting the cap-in-place closure method when coal ash waste ponds are located in floodplains. This method, where coal ash is left in place with a cap to cover it, can lead to toxic pollution leaks, especially during floods or extreme weather events. Instead, a clean closure approach should be mandated, which includes the excavation and removal of coal ash to compliant landfills or its beneficial reuse in certain products.
Secondly, strengthen oversight during the closure and cleanup of coal ash sites. Ensure proper excavation, transport, reuse, and disposal of coal ash without releasing toxic contaminants into the air, soil, or water. This includes providing oversight in communities, at work sites, along transport routes, and at final disposal sites to prevent the release of toxins.
Thirdly, improve groundwater monitoring at coal ash facilities. The EPA should enforce strict compliance with groundwater monitoring requirements, including the installation of monitoring wells and the use of proper monitoring techniques. This will help detect contamination early on and prevent further pollution of water sources.
Additionally, hold coal ash facilities accountable for improper disposal and non-compliance with regulations. The EPA should work closely with state partners to investigate and enforce consequences for facilities that fail to meet standards, protecting both public health and the environment.
Finally, provide financial assistance to communities affected by coal ash contamination through programs like the EPA's Technical Assistance Services for Communities (TASC) Program. Empowering residents to actively participate in the cleanup and closure of toxic coal ash dumps ensures a just transition and meaningful community involvement.
By implementing these measures, oversight can be improved to prevent toxic coal ash from entering water supplies, safeguarding communities, and protecting natural resources.

Enforce federal CCR rules to prevent coal ash cap-in-place closure in floodplains
Coal combustion residuals (CCR) or "coal ash" is a toxic waste generated by burning coal. It is one of the largest industrial waste streams in the US. Coal ash contains fly ash, bottom ash, boiler slag, and flue gas desulfurization sludge.
The US Environmental Protection Agency (EPA) has taken steps to protect groundwater from coal ash contamination. The EPA's actions include denying deadline extension requests, citing deficiencies in groundwater monitoring, cleanup, and closure activities. The EPA has also proposed a federal permitting program for CCR disposal and finalized national regulations for its safe disposal.
To prevent coal ash cap-in-place closure in floodplains, it is essential to enforce the 2015 federal CCR Rule's prohibition on this practice when the coal ash impoundment is in contact with groundwater. This rule applies to coal ash waste ponds located in floodplains susceptible to floods, which can destabilize toxic pollution.
The EPA should provide oversight during closure and cleanup to ensure coal ash excavation, transport, reuse, and disposal are done safely without releasing toxic contaminants into the air, soil, or water. Financial assistance should be provided to frontline communities to empower residents to participate in the cleanup and closure of toxic coal ash dumps.
State and local officials must consider the economic and environmental impacts of coal pond closures and assist communities in advocating for the best outcomes. The US Congress must recognize the need for additional financial resources in communities facing coal plant closures to ensure equitable transitions.

Provide financial assistance to communities to enable meaningful participation in cleanup
Coal ash is the toxic waste generated by burning coal, and it is one of the largest industrial waste streams in the US. Coal ash contamination can have a detrimental impact on communities, particularly those already burdened by high levels of pollution.
Financial assistance can play a crucial role in enabling communities to participate actively in cleanup efforts and ensure a just transition. The US Environmental Protection Agency (EPA) has recognized the importance of supporting communities in their efforts to address coal ash pollution. The EPA provides assistance through stakeholder engagement, technical support, compliance assistance, and enforcement to hold facilities accountable for improper coal ash disposal.
One way to provide financial assistance to communities is through grants. For instance, the EPA's Technical Assistance Services for Communities (TASC) Program offers grants to empower residents to engage meaningfully in the cleanup and closure of toxic coal ash dumps. Similarly, the Washington State Department of Ecology offers Independent Remedial Action Grants to help local governments address contaminated properties. These grants enable voluntary cleanup without a legal agreement, providing fee-based assistance to eligible communities.
In addition to government initiatives, organizations like Earthjustice offer recommendations for financial assistance. They emphasize the importance of enforcing the CCR Rule's prohibition on cap-in-place closure when coal ash waste ponds are susceptible to floods, which can lead to toxic pollution. By providing financial assistance to frontline communities, they can actively participate in the transition to cleaner energy sources while ensuring the safe cleanup and disposal of coal ash.
Financial support can also come in the form of grant awards, as demonstrated by the Department of Energy's $18.9 million grant initiative. These grants focus on reinvestment in disadvantaged communities impacted by nuclear defense missions and environmental cleanup sites. By strengthening relationships with these communities, the grants promote inclusive engagement practices and support projects that align with community development goals.
Overall, providing financial assistance to communities is a crucial aspect of enabling their meaningful participation in coal ash cleanup efforts. Through grants, awards, and dedicated government support, communities can take an active role in protecting their health, environment, and natural resources.

Reuse coal ash in concrete, drywall, and other products to reduce landfill waste
Coal combustion residuals (CCRs) or "coal ash" is the toxic waste generated by burning coal. CCRs include fly ash, bottom ash, boiler slag, and flue gas desulfurization sludge. CCRs are found in a plethora of products, including concrete, drywall, agricultural fertilizer, structural foundation materials, and roadways.
CCRs can be reused in concrete and drywall, preventing coal ash pollution. CCRs can replace cement as a key ingredient in concrete, and it can be used to build roads and foundations. This type of reuse is called "beneficial reuse" and is regarded by many environmentalists, regulators, and industry sources as preferable to storage in landfills.
In 2020, America reused 40 million tons of CCRs, with two-thirds of this being ash. CCRs are commonly used in concrete and drywall production, where the toxic chemicals are chemically bound, making it unlikely that they will escape. This process is called "encapsulated use" by the EPA.
The use of CCRs in concrete and drywall offers several benefits. Firstly, it reduces the use of virgin resources, as CCRs can replace cement in concrete and gypsum in drywall. Secondly, it lowers greenhouse gas emissions by reducing the need for cement production, which is carbon-intensive. Thirdly, it improves the strength and durability of materials. Finally, it reduces the cost of coal ash disposal.
However, there are challenges to beneficial reuse. Firstly, there are significant cost and technical barriers to drying out and reusing coal ash from landfills. Secondly, companies are often resistant to this option. Additionally, stakeholders worry that if regulations around beneficial use are too strict, more coal ash may end up in landfills or ponds, polluting groundwater. If regulations are too weak, beneficial use could lead to unknown contamination.
