EREF Webinar – Functional Stability and the End of Post-Closure Care at Municipal Solid Waste Landfills

Mon, Dec 4, 2017
11:00 AM - 12:30 PM PST

This presentation will discuss the timeframe and issues surrounding post-closure care (PCC) at municipal solid waste (MSW) landfills, and outline a performance-based methodology that has been successfully applied at a number of sites in North America and Europe. The methodology, termed “Evaluation of Post-Closure Care (EPCC),” provides a modular approach for sequentially evaluating each of the four landfill PCC elements (leachate management, landfill gas management, groundwater monitoring, and cover maintenance) in terms of “functional stability.” EPCC was developed by a multi-disciplinary team led by Geosyntec under a grant from the Environmental Research & Education Foundation (EREF), and published in 2006 as the Evaluation of Post-Closure Care (EPCC) Methodology.

This presentation will provide an update on the status of PCC regulations in the U.S., with a focus on promulgation of performance-based approaches. Thereafter, we will explore the following attributes of evaluating the post-closure condition of a landfill adopting a performance-based approach:

This webinar will:

Highlight case studies on how EPCC can be applied to progressively demonstrate that certain PCC elements can be safely modified (reduced) or ended.
Provide examples of passive control measures that require only minimal monitoring and maintenance, activities that may be compatible with or even integrated into several beneficial reuse options at a closed landfill.

Suggest mechanisms for transfer of responsibility from a regulated PCC program to a post-regulatory custodial care program after functional stability is demonstrated and confirmed through monitoring.
