Coal Combustion Residuals

In April 2015, the EPA published its Disposal of CCR from Electric Utilities final rule in the Federal Register. The rule regulates the safe disposal of coal ash, or CCRs, from coal-fired power plants. As rules and regulations around CCR landfills and surface impoundments become stricter, owners and operators of coal-fired plants face many challenges.

With looming changes to rules and regulations, it’s important for coal-fired power plants to understand their obligations. First, to know where they stand, and second, to have a clear compliance path moving forward. Learn more about the EPA’s January 2022 update to actions on the CCR rule.

Coal Combustion Residuals Professional Services and Construction

The CCR Rule establishes technical requirements for CCR landfills and surface impoundments under subtitle D of the Resource Conservation and Recovery Act, the central federal regulatory program governing recycling and disposal of solid waste. APTIM has some the brightest and most experienced professionals in the business. Our goal is to guide each client through the regulations for compliance in alignment with their sustainability objectives all the way through closure.

Following guidelines in the CCR Rule, ash storage ponds (where CCR are stored) that required additional testing of groundwater and an assessment of corrective measures (ACM) are identified. This process identifies what potential actions can be taken where constituents were found at statistically significant levels above site-specific groundwater protection standards. The process included two years of groundwater monitoring to confirm that constituents above groundwater protection standards exist in onsite monitoring wells. In general, levels of constituents are stable, and in some cases decreasing.

The rule requires that a coal ash basin close if it:

  • No longer receives coal ash;
  • Does not meet certain EPA structural standards;
  • Does not meet certain EPA groundwater standards;
  • Or, does not comply with EPA’s location restrictions.
