It takes a visionary to leave a legacy, and Richard Bass, founder of Snowbird Ski and Summer Resort in Utah, was such a man. For starters, Bass is acknowledged as the first person in the world to …

Part 1: The regulation of CCR in the United States: Geosynthetics and barriers

August 1, 2017

The regulation of coal ash (coal combustion residuals or CCR) has significantly expanded the market for geosynthetics within the United States. Further, there is interest in these regulations around the globe in every country using coal as an energy source. These regulations are the result of recent environmental incidents. The regulations call for the increased …

CCR management using geotextile tubes

Introduction Since the late 1800s, coal has played a leading role in U.S. production of electrical energy. Coal-fired power plants have provided reliable electrical power from the earliest days when power plants were run with hand-fed coal to heat boilers to produce steam. The introduction of pulverized coal led to improvements in the electrical-generation process …

Using geosynthetics for macroencapsulation for CCR on-site clean closure

Coal combustion residuals (CCR) have been used for many years in the construction of berms and engineered structural fill applications, including embankments for highways, dikes, and levees. However, large, unencapsulated structural fill projects have become a focus of environmental concerns due to potential leaching of metals and structural failures. Cap-in-place of CCR surface impoundments is …
