More water questions from GA-EPD about TPM strip mine too near Okefenokee Swamp 2021-12-07

Since September, GA-EPD has twice more asked the miners for more information on their permit applications to strip mine for titanium dioxide too near the Okefenokee Swamp. We have more questions beyond those. You can ask GA-EPD questions, and to deny the mining permit applications.

On October 20, 2021, the Georgia Environmental Protection Division (GA-EPD) asked more questions about water: retention, disposal, reclamation. The miners’ answer on November 19th apparently was not satisfactory, because on December 7, 2021, GA-EPD asked more water questions.

TPM Ponds and Another GA-EPD Letter

I’ve got another: how can Twin Pines Minerals (TPM) with a straight face promise “zero discharge of wastewater” and in the next paragraph say “Overflow from the process water primary overflow pond may occur due to heavy rain events.” That’s exactly what happened after Hurricane Irma at three north Florida Chemours mine sites where TPM was processing tailings, resulting in TPM still being under a Florida Consent Order. What if wastewater overflows into the Okefenokee Swamp during a hurricane or other “heavy rain event”? What stops wastewater even in TPM’s proposed retention ponds from seeping down into the Floridan Aquifer, from which we all drink?

And another: TPM still shows piezometers for water monitoring on property it does not own, with a disclaimer that it has no access to. So how will TPM monitor that area, which is downhill towards the Okefenokee Swamp, which is the headwaters of the St. Marys and Suwannee Rivers?

You can ask GA-EPD for a moratorium on mining permits, or to deny the permits, or at the very least to examine them very thoroughly and produce the equivalent of the Environmental Impact Statement that the Army Corps should have been working on.

Floridians, this mine site is upstream from Florida, and you can also use these forms.

Mining moratorium: NWPR WOTUS and Army Corps on Okefenokee mine site –WWALS to EPD 2021-09-27

The Army Corps’ excuse to abdicate oversight over the strip mine site near the Okefenokee Swamp was overturned in a court case this August, so the Corps should take that back up.

Meanwhile, WWALS asked GA-EPD to impose a moratorium on all mining permit applications until the ramifications of that court case are sorted out, which could take months or years.

You can ask GA-EPD for that moratorium, or to deny the permits, or at the very least to examine them very thoroughly and produce the equivalent of the Environmental Impact Statement that the Corps should be working on.

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.
