Description
The engineered turf final closure system (ClosureTurf®) is installed or awaiting installation on over 4,000 acres (1,619 hectares) of waste containment facilities including coal combustion residual (CCR) units, industrial and municipal solid waste landfills. A significant benefit of the engineered turf cover system over traditional soil covers is performance and resiliency under extreme weather conditions. The engineered turf cover system performs well during high rainfall intensities and/or high winds by protecting the containment facility from erosion or damage to the closure system and underlying subgrade/waste. This leads to measurable improvement in stormwater runoff quality and reduction in post-closure maintenance costs. An overview of the engineered turf cover system is presented and a comparison with traditional soil covers including real-world performance evaluations of the installed engineered turf cover system on CCR, industrial and municipal solid waste facilities. Installations included in this study were subjected to over twenty-five (25) hurricanes, named tropical storms or typhoons, and tornado events. Based on airport weather stations, the engineered turf cover system has experienced rainfall intensities exceeding 5 in/hr (127 mm/hr) and wind speeds over 80 mph (129 km/h) while maintaining integrity. The following paper will be beneficial to site owners and engineers seeking a safe, cost- effective, resilient final closure solution of CCR landfills and impoundments.
