Coal Ash Basin Liner
Benefits of EPI PVC Geomembranes for Coal Ash Basin Closure
As we transition toward cleaner energy options, many coal plants are being retired. Under RCRA Subtitle D, more than 500 blackwater and coal ash basins or impoundments are slated for closure in the United States. In order to effect permanent closure, these ash basins will require stable geomembrane liners. While there are two main types of basins used for coal ash storage -- dry storage basins and wet storage basins, the wet basins are the main concern and targets for closure. Because preservation of water quality is the paramount goal for the companies who own the basins, it's important to choose the right geomembrane product.
Due to its low cost, durability, and application across multiple industries,
PVC has been a trusted and preferred choice since the 1950s.
