Phase II: Application of an Approved Alternative Intermediate Cover

Wednesday, September 27, 2017
9:35 – 10:05
Room 321

Moderator: Andrew Quigley, Director, Environmental Management, Charleston County Government, South Carolina

In 2016, after completing a pilot study, officials at the Hernando County Landfill received approval from the Florida Department of Environmental Protection (FDEP) to use Posi-Shell® Cover System as an alternative intermediate cover (AIC) at the Hernando County Northwest Management Facility (NWWMF) Class I Landfill located in Brooksville, Florida. It’s the first solid waste facility in Florida to be permitted to use the AIC, which will save eight percent of landfill airspace, which translates into additional $11M in revenue. The presentation will discuss the challenges and cost benefits of applying the AIC at the NWWMF.

Following the presentation, participants will be able to understand the process of permitting a use of alternative AIC at a Class I landfill.
