Fly ash availability is decreasing due to plant closures across 25 states. Over 11% of coal fired generating capacity has been reduced, with over 40% reductions in the Midwest, Mid-Atlantic, and Southeast regions. This has led to over 7 million tons less fly ash being produced annually. The document was presented by Megan Dangel from Central Plains Cement Company at a concrete paving workshop to discuss issues regarding decreasing fly ash supply.
