In April of 2015, the Disposal of Coal Combustion Residuals from Electric Utilities Rule went into effect. The Rule regulates the safe disposal of coal combustion residuals (CCRs) generated from coal-fired power plants. The Rule was established in response to recent incidences in which coal ash or coal ash leachate contaminated fresh water supplies, including the catastrophic failure of an ash impoundment that resulted in a large-scale release of coal ash and flooding of more than 300 acres of land.
This rule addresses risks from coal ash disposal through the establishment of specific requirements for CCR landfills and surface impoundments under Subtitle D of the Resource Conservation and Recovery Act (RCRA). In particular, it specifies design criteria for landfills and impoundments (including location restrictions), requires structural integrity assessments of existing and future facilities, and dictates requirements for their ultimate closure. Furthermore, it stipulates strict monitoring and reporting requirements, which includes groundwater monitoring, emergency action plans, flood control plans, and post-closure care.
AECOM offers engineering services for all facets of the CCR rule. From groundwater monitoring to pond closures and new landfill design, we have the experienced professionals capable of delivering successful projects. Furthermore, combining our engineering resources with the Design-Build or construction capabilities of Process Technologies, we can deliver these projects on a turnkey basis.
