WASHINGTON – Today, the U.S. Environmental Protection Agency issued a proposed denial of Alabama’s permit program to manage coal combustion residuals – commonly known as CCR or coal ash – in landfills and surface impoundments. In its first proposed denial of a state coal ash permit program, EPA finds that the Alabama permit program is significantly less protective of people and waterways than the federal regulations require. Under the federal regulations, surface impoundments cannot be closed if, once closure is complete, the coal ash continues to be saturated by groundwater. Facilities must prevent groundwater from infiltrating and flowing out of the closed unit to prevent additional groundwater contamination. In contrast, Alabama does not require that groundwater infiltration be adequately addressed during the closure of these coal ash units.
Today’s action advances the Biden-Harris Administration’s commitment to protect all communities from pollution and advance environmental justice, with a strong focus on the need to address health and environmental impacts, including for marginalized and overburdened communities that bear a disproportionate burden of pollution.
“Exposure to coal ash can lead to serious health concerns like cancer if the ash isn’t managed appropriately,” said EPA Administrator Michael S. Regan. “Low-income and underserved communities are especially vulnerable to coal ash in waterways, groundwater, drinking water, and in the air. This is why EPA works closely with states to ensure coal ash is disposed of safely, so that water sources remain free of this pollution and communities are protected from contamination.”
EPA has approved three other state CCR permitting programs. However, EPA is proposing to deny the Alabama CCR permit program application because it does not meet the standard for approval under the Resource Conservation and Recovery Act. Under this law, each CCR unit (i.e., landfills or surface impoundments) in the state must achieve compliance with either the federal CCR regulations or state criteria that EPA has determined are at least as protective as the federal criteria. The Alabama Department of Environmental Management (ADEM) largely adopted the language in the federal CCR regulations into its state regulations. However, when EPA reviewed Alabama’s CCR permits, EPA found that the permits were not as protective as the federal CCR regulations.
EPA identified deficiencies in ADEM’s permits with closure requirements for unlined surface impoundments, groundwater monitoring networks, and corrective action requirements. EPA discussed these issues with ADEM; however, the state agency has not revised its permits or supplemented its application to explain how such permits are as protective as the federal CCR requirements.
Should EPA’s proposed denial of Alabama’s coal ash permit program be finalized, the consequence would be that facilities will still be required to comply with the federal CCR regulations. If EPA determines that there are any immediate threats to human health or the environment posed by CCR facilities (whether unpermitted or currently permitted by the state), EPA will consider using all available authorities, including enforcement and response authorities provided under federal law.
EPA is soliciting comments on this proposal for 60 days, during which an in-person public hearing will be held for interested persons to present information and comments about this proposed program.

Background
Coal ash is a byproduct of burning coal in coal-fired power plants that, without proper management, can pollute waterways, groundwater, drinking water, and the air. Coal ash contains contaminants like mercury, cadmium, chromium, and arsenic associated with cancer and other serious health effects.
EPA issued a final rule in April 2015 regulating CCR under RCRA and establishing minimum national standards governing the disposal of CCR from electric utilities in landfills and surface impoundments. At the time the CCR rule was issued, EPA did not have authority under RCRA to regulate CCR disposal through state permit programs. Instead, utilities were responsible for directly implementing the requirements of EPA’s 2015 CCR rule, which were enforceable only through citizen suits.
Congress recognized the essential role of the states in its passage of the 2016 Water Infrastructure Improvements for the Nation (WIIN) Act which, among other changes, amended RCRA to give states the authority to operate permit programs, provided EPA determines that the state’s requirements are as protective as the federal standards. Now, states may develop and submit coal ash permit programs to EPA for approval. Applications must provide evidence of permit programs or other systems of prior approval and be as protective as the federal regulations currently in place. Once approved, the state permit programs operate in place of the federal management standards for coal ash disposal.
Once states have approved CCR permit programs in place, the WIIN Act contains provisions for how and when states must update their approved programs when changes are made to the CCR requirements at the federal level. EPA encourages states with coal ash facilities to apply to establish their permit programs, as the states of Oklahoma, Georgia, and Texas have done. Many states have engaged with EPA on how to set up their programs and how their current state regulations could be revised to incorporate the federal requirements.
