Geosynthetics are uniquely suited
October 1st, 2019
Geosynthetics are found in the strangest of places. But that just speaks to how versatile and useful they are for a wide variety of applications. Dewatering, energy-site closure, erosion control, reinforcement and stabilization are just a few applications that geosynthetics address in this issue. In addition, many of the geographic areas discussed here are sensitive […]
Lessons learned in alternative coal ash pond closure design and construction
October 1st, 2019
By Anna M. Saindon Coal ash pond closures often face unique challenges due to location, available borrow soils and construction constraints. These challenges can lead to alternative methods of closure to comply with Resource Conservation and Recovery Act (RCRA) Subtitle D and coal combustion residuals (CCR) regulations. This article summarizes the construction of the first […]
An innovative cover system to close an ash/sludge impoundment
August 1st, 2019
By Paul C. O’Malley, José L. Urrutia and Don DiGuilio The two projects (confidential client) are industrial sites consisting of coal ash and by-product sludge located in the southeastern United States. The projects included 70 and 67 acres (28 and 27 ha) in closure areas, and the waste source consisted of industrial sludge with a […]
EPA proposes approval of Georgia’s coal ash permit program, encourages other states to follow suit
June 25th, 2019
The U.S. Environmental Protection Agency (EPA) is proposing to approve Georgia’s permit program for the disposal of coal combustion residuals—commonly known as coal ash—from certain coal-fired power plants. “EPA encourages other states to follow Georgia’s lead and assume oversight of coal ash management within their borders,” said EPA Administrator Andrew Wheeler. “EPA is committed to working with […]

Geosynthetics and coal combustion residuals
October 1st, 2018
According to the World Bank Group, in 2015 coal produced 41% of the world’s energy and about 34% of the energy production in the United States. While global warming and pollution are serious challenges according to most scientific evidence, and coal burning is cited as one cause of both, there are many staunch advocates of […]
