Kanawha Stone Company (KSC) forms in March 1973, blasting and excavating calcium sulfate within an active chemical plant, owned and operated by Allied Chemical. Kanawha Stone’s product, a gypsum by-product of the chemical process to produce hydro-chloric acid, is sold as road base aggregate.


The federal office of Surface Mining (OSM) contacted Kanawha Stone after ABC’s “20/20” television program ran an exposé on the threat of rocks ready to topple on a community. Such rocks were the residue of prior mining operations at Tank Rock in Mingo County, WV. OSM found Kanawha Stone through DuPont Chemical, who had a plant adjacent to the Allied Chemical/Kanawha Stone operations in Nitro, WV. Tank Rock was Kanawha Stone’s first of many mine reclamation projects with terrain requiring drills to be airlifted by helicopter.
