Coal Ash Containment

Question: What is coal ash and why is it considered a growth opportunity for the lining industry? Answer: Coal combustion residuals (CCRs), commonly known as coal ash, are byproducts of the combustion of coal at power plants. Coal ash in liquid form is disposed of at large surface impoundments (ponds), while its solid form goes into landfills. Coal ash contains high concentrations of contaminants such as mercury, cadmium, arsenic and other substances associated with serious health issues. The Environmental Protection Agency has determined that “without proper protections, the contaminants in coal can leach into groundwater and often migrate to drinking water sources, posing significant health public concerns.” The EPA is regulating coal ash with new rules that will ensure the safe disposal and management of combustion residuals. Although the regulations include several methods of oversight, one specific new requirement is for geosynthetic liners to be installed at all landfills and surface impoundments to prevent contamination of ground water from ash disposal sites. BTL's reinforced polyethylene liners are the best in the industry for strength, puncture resistance, and UV and chemical stability. BTL’s liners are available in large factory panels, and are molecularly bonded at the seams for unparalleled leak resistance.
