Description
DEMONSTRATING EQUIVALENCY OF CLOSURETURF AS A VIABLE ALTERNATIVE TO TRADITIONAL CCR FINAL COVER SYSTEMS Authors Mr. Tyler Schmidt - United States - Burns & McDonnell Abstract When designing final cover systems for the closure of CCR units, owners must select materials that meet regulatory criteria while weighing facility-specific needs and challenges. ClosureTurf, an artificial turf cover system component, is often a viable solution for managing a facility’s needs and challenges, from preconstruction (such as optimizing earthwork) to post-closure (such as managing a low-maintenance artificial erosion layer). However, obtaining approval from a state agency or to comply with the requirements in the CCR to design a final cover system with ClosureTurf may require complex permitting and design effort. Although ClousreTurf has been implemented at over 30 CCR sites in the United States, many state regulatory statutes don’t include provisions for granting approval for an artificial turf component of a final cover system, without requiring applicants to apply for a variance and demonstrate equivalency. To support equivalency demonstrations to state regulatory agencies, WatershedGeo has performed case studies and experimentation on ClosureTurf in the process of developing a robust engineering design manual. This presentation will explore several technical topics of this engineering design manual and how to apply these design methodologies in an equivalency demonstration. This presentation will also provide advice and proven strategies for building a clear, concise, and logical equivalency demonstration for a streamlined regulatory review process.
