FGI SHORT COURSE ADDRESSES COAL COMBUSTION RESIDUALS (CCRs)

The Fabricated Geomembrane Institute (FGI) presented a short course in Charlotte, North Carolina on 6 November 2019 at the Center City Building to a sold out crowd.  The short course was organized by the FGI and was offered in collaboration with the University of North Carolina at Charlotte (UNCC).  

The excellent and timely presentations focused on the regulations, placement, and management of CCRs, with an emphasis on using geosynthetics.  The morning portion of the short course focused on regulatory issues, containment applications, CCR static properties,and seismic behavior of CCRs.  For example, a presentation by JR Register of Consumers Energy, focused on the current and emerging CCR regulatory issues, while Evan Andrews of Duke Energy provided insight into using geosynthetics to manage, cover, and contain CCRs.  Gary Zych of American Electric Power (AEP)reviewed containment applications for CCRs for AEP facilities. Vincent Ogunro of UNCC followed with an informative presentation on the static material properties and treatment of CCRs. Lastly, Professor Bill Wolfe of The Ohio State University described the seismic behaviors of CCRs and conducting liquefaction analyses for CCRs to wrap up the morning portion.  

The afternoon presentations focused on the practical applications of geosynthetics for CCR management, closure, and containment. For example, Allen Bullock of Leister and Matthew Roy of DemTech provided a demonstration of geomembrane seaming, patching, and testing.  Timothy D. Stark of the University of Illinois at Urbana-Champaign reviewed the importance of geomembrane wrinkles in leakage rates and leak location surveys. Ken Daly of Wood PLC gave an informative presentation on local practices for managing CCRs. Sam Allen of TRI Environmental provided insight on leak location surveys.  Finally, Joe Troxell of S&ME described the largest fabricated geomembrane project in the world, i.e.,Columbus, Ohio Upground Water Reservoir.

Many attendee questions, comments, and experiences made the course a greatsuccess. The topics andspeakers from the successful shortcourseare shown below:

FGI Legacy and History: Celebrating Nearly 40 Years of Innovation in Geomembranes

Written by Brian Fraser & Pat Elliott – October 28, 2025
Download

Geomembranes have played a vital role in environmental containment across North America for over six decades. Their journey began in1957 when the U.S. Bureau of Reclamation conducted early tests on PVC geomembrane installations. A landmark moment came in 1968 with the first formally specified PVC geomembrane installation for Montana’s Helena Valley Canal marking the beginning of a new era in engineered containment solutions.

The Fabricated Geomembrane Institute (FGI) traces its roots to the PVC Geomembrane Institute (PGI), founded in 1988. PGI was established to represent a growing community of manufacturers, fabricators, and installers dedicated to advancing geomembrane technology. In 2009, recognizing the expanding scope of factory-fabricated materials, PGI rebranded as FGI. This shift emphasized the advantages of controlled factory production over field fabrication, aligning with industry trends and technological advancements.

FGI is housed within the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign. As an academic-industry consortium, it is committed to research, education, and technology transfer in the field of flexible geosynthetics. In June 2025, the institute adopted a new name—Flexible Geomembrane Institute—to reflect its broadened mission, which now includes both roll stock and field-fabricated liners.

Mission and Vision
FGI operates as a non-profit, industry-sponsored institute focused on advancing the use of flexible geomembranes. Through collaborative research, educational outreach, and technical guidance, FGI has become a cornerstone of innovation and knowledge-sharing in the geosynthetics community.  Professor Timothy D. Stark, Technical Director of the FGI, and the Board of Directors remain committed to advancing and growing the association while providing a high level of support to our members.

Honoring the Pioneers & Contributors
As FGI approaches its 40th anniversary, we extend heartfelt gratitude to the many individuals who have shaped both the institute and the broader geomembrane industry. From early pioneers to long-standing supporters, your contributions have left a lasting legacy. While the list is extensive, we acknowledge that some names may be inadvertently omitted and offer our sincere apologies.

After sixteen years as the Fabricated Geomembrane Institute (FGI), we’re proud to announce that we have officially changed our name to the Flexible Geomembrane Institute. This change marks an exciting new chapter for our organization, expanding our mission and further solidifying our commitment to the innovative field of geomembrane technology, while maintaining focus on factory fabrication and modular construction.

This updated name better reflects the evolving landscape of the industry and the diverse needs of FGI’s growing community of members and industry professionals. By emphasizing flexibility, our new name speaks to the Institute’s broader reach, while staying true to the foundational principles and deep expertise in geomembrane applications.

"Expanding the FGI to focus on all flexible geomembrane installations allows us to include field fabrication with our long-term interest in factory fabrication and modular construction," said Dr. Timothy D. Stark, Technical Director of FGI. "As we continue to innovate and grow, we are still the same great organization, providing useful content on current and emerging trends in the industry." Patrick Elliott, President of the FGI also commented, “This simple but strategic change helps align our goals and work closer to represent the needs of our members and industry. While our core focus will always be on factory fabrication the fact remains, we want to provide industry research and technology to focus on providing the best products and techniques to solve all project challenges.”
