Event Date: October 16-18, 2017

GEI has teamed with the Electric Power Research Institute (EPRI), the International Society of Technical & Environmental Professionals, Inc. and the Center for Biomedical & Toxicological Research at Florida State University to organize the 7th International Symposium and Exhibition on the Redevelopment of Manufactured Gas Plant Sites (MGP 2017). This year’s conference is being held at the Sheraton Hotel in New Orleans, Louisiana on October 16-18, 2017.

Carrying on the spirit and traditions of past GEI-sponsored MGP conferences, MGP 2017 provides a forum for utilities, regulators, consultants, and contractors to share their experiences and ideas. In addition, MGP 2017 will give the next generation of industry experts a terrific opportunity to further develop relationships in the marketplace. The conference agenda will consist of workshops and two days of exhibits, poster presentations, and engaging technical sessions.
