Free webinar: GCLs for coal ash and caustic leachate applications

Recent promulgation of the new US EPA rule governing disposal of coal combustion residuals from electric utilities is driving increased use of polymer amended Geosynthetic Clay Liners (GCLs).

This free webinar will address:

• What are the benefits and risks of polymer amendment in GCLs from a chemical compatibility, hydraulic performance, and a slope stability perspective?
• During the material evaluation and design stages, how to verify that the GCL sample that is being tested for chemical compatibility and hydraulic performance is consistent in polymer amendment with the GCL sample that is being tested for shear strength?
• During the procurement and construction stages, how to verify that the GCL that is being procured and installed on site is consistent in polymer amendment with what was evaluated and specified?

When: Tuesday, Aug. 4, 1-2 p.m. EDT or Wednesday, Aug. 5, 1-2 p.m. EDT

Presenters: John M. Allen, P.E., TRI, and Scott P. Solotorovsky, CETCO
