More questions about strip mine near Okefenokee Swamp –GA-EPD to miners 2021-09-10

GA-EPD last Friday sent another request for clarifications to the miners about their proposed strip mine far too near the Okefenokee Swamp.

Meanwhile, you can ask GA-EPD to reject the five permit applications from Twin Pines Minerals for that strip mine, or at least to thoroughly study with independent review potential effects of that mine on the Okefenokee Swamp, the Suwannee River, and the Floridan Aquifer.

Most of the new questions are about how bentonite clay will be used. The Georgia Environmental Protection Division (GA-EPD) has actually been asking about that since December 5, 2019.

A question GA-EPD did not ask is what if the clay gets into waterways with fish? Bentonite in small particles can get into the gills of fish and suffocate them, and bentonite can also deplete oxygen: see Identification of Oxygen-Depleting Components in MX-80 Bentonite, Torbjörn Carlsson and Arto Muurine, Cambridge University Press, 01 February 2011.

GA-EPD also asked about water draining into the Floridan Aquifer or into rivers, or water moving in the other direction.
