Geosynthetic Liner Systems for Coal Combustion Residuals (CCR) Containment & Effluent Limit Guidelines (ELG) Compliance
for the POWER industry
CCR, also referred to as coal ash, is created when coal is burned from power plants to generate electricity.
On July 26, 2016, the United States Environmental Protection Agency (USEPA) enacted rules requiring the application of subtitle D of the Resource Conservation and Recovery Act (RCRA) to the disposal of CCR in certain inactive CCR surface impoundments. This regulation thus requires composite closure systems similar to the requirements specified for the solid waste industry (referred to as “Subtitle D”). In addition to CCR closure, some CCR sites may require base liner systems, utilizing geosynthetic liner systems, to help prevent contaminants in CCRs from leaching from the CCR unit and contaminating groundwater. ESI has extensive experience installing composite base liner and closure systems in this industry – some examples of which are provided in our projects section.
In addition to CCR containment, in 2015, the EPA instituted new regulations for the containment of wastewater discharge from steam electric power generation facilities. Meeting this new regulation may require power companies to use composite geosynthetic liner systems in wastewater discharge ponds to ensure proper containment.
