Floridan Aquifer withdrawals affect the Okefenokee Swamp, so how could TPM’s withdrawals not? 1995-04-11

Water withdrawals from the Floridan Aquifer affect water levels and quality in the Okefenokee Swamp, a pair of researchers concluded 24 years before Twin Pines Minerals of Alabama proposed to withdraw 2.4 million gallons per day from the Aquifer for a titanium mine within a few miles of the Swamp:

Abstract. A rapid response is observed between water level fluctuations in the Okefenokee Swamp and water levels in the underlying Floridan Aquifer. A lag of approximately one month is common, and a hydraulic diffusivity of 3.83 x 10-3 m2 s-1 best matches the calculated aquifer response to the swamp water level perturbations. The magnitude of leakage between the swamp and the aquifer is uncertain because of a lack of knowledge about the specific storage coefficient in the aquitard separating the swamp and the aquifer which has not been explicitly measured. An intermediate value of specific storage within the likely range of values results in a down- ward vertical flow of 1.2 meters of water per year. This induced recharge can significantly alter the natural water balance within the swamp. Such a large loss of water from the swamp may be responsible for observed pH and water level changes, and increased beavy metal accumulations in aquatic organisms in the swamp.

We cited that study[5] on page 4 of the Suwannee Riverkeeper comments to USACE about TPM, just after noting Twin Pines application to withdraw 4.32 million gallons per day (mgd) of Floridan Aquifer water much closer to the Swamp than any other permitted withdrawal. TPM’s own hydrology study in that withdrawal application shows a cone of depression in the Floridan Aquifer extending under the Swamp:

How could that not affect Swamp water levels and content?

As pointed out to the Corps by Okefenokee Swamp Park (OSP), any change to the water level in the Swamp would Continue reading

Comments: 20,338 on titanium mining near Okefenokee Swamp –USACE 2019-09-12

If this and the 27 news articles on radio, TV, and newspapers in Georgia and Florida, several of them carried by Associated Press across the country, plus the ten op-eds and three editorials, is not enough to establish controversy, I wonder what is. Maybe still more comments and news articles and social media?

Nedra Rhone, Atlanta Journal-Constitution, 13 September 2019, Mining proposal near Okefenokee draws more than 20K comments from public

The Suwannee Riverkeeper, on Thursday, sent 22 pages of questions to the Corps and the Georgia Department of Environmental Protection asking the agency to deny the permit. The Riverkeeper joined the SELC and other organizations and individuals in asking the Corps to prepare an Environmental Impact Statement, the highest level of analysis available when a proposed federal action may significantly affect the quality of the human environment.

Also in that AJC story:

Commenters expressed concerns ranging from the acres of wetlands that would be lost to what they considered inadequate studies conducted to determine the potential impact of the mine.

In a letter to the Corps, the Southern Environmental Law Center said Continue reading

Re: Applicant: Twin Pines Minerals, LLC, Application Number: SAS-2018-00554

Dear Colonel Hibner,

Suwannee Riverkeeper for WWALS Watershed Coalition (WWALS) asks USACE:

  • to reject the subject Application from Twin Pines Minerals (TPM), given the inappropriate location which would over the years move ever closer to the Okefenokee Swamp, which is the headwaters of the Suwannee and St. Mary’s Rivers, combined with the numerous omissions from the Application regarding the wide hydrogeologic, water quality, ecologic, and economic ramifications of the proposed mining, and the numerous other mines relevant to the proposal.

If USACE continues to process the Application, WWALS requests USACE:

  • to require a complete hydrogeological assessment and report, a full Environmental Impact Statement (EIS), and an economic analysis, with all three covering all the relevant features, mines, and applications in south Georgia and north Florida, including at least those outlined in this letter.
  • to accept comments until at least ninety days after all these documents are submitted to USACE and distributed to the public, preferably on USACE’s website, without requiring site visits to Albany to get them.
  • to hold public hearings in Georgia and Florida for further independent input and review after sufficient time (months or years) for independent third-party review.

The proposed Charlton County, Georgia, TPM mine site is hydraulically upgradient from the Okefenokee Swamp and within close proximity to the boundary of the Okefenokee National Wildlife Refuge (ONWR), with its 600,000 visits per year for boating, birding, and fishing, with more than $60 million annual economic effects including hundreds of jobs supported directly or indirectly, plus hunt clubs surrounding the Swamp. The Swamp provides ecosystem services of great economic values, including storm protection, water quality provisioning, support for nursery and habitat for commercial fishing species; and carbon storage, plus those hunt clubs depend on the Swamp. Any pollution of the Swamp or change in surface or groundwater levels could adversely affect not only ONWR and nearby areas, but also the Okefenokee Swamp Park (OSP) near Waycross, in Ware County, GA, and Stephen C. Foster State Park (SCFSP) in Charlton County, via Fargo in Clinch County. Visitors come from Jacksonville, Florida, Brunswick and Valdosta, Georgia, and from much farther away to visit the Okefenokee Swamp. The Swamp is a treasure to the entire nation and the world.

The stigma of a strip mine next to the swamp could cause people to turn away, taking their dollars with them. Who wants to boat, fish, bird, or hunt next to a strip mine?

Need EIS, public hearings –Okefenokee Swamp Park to USACE about titanium mine 2019-08-22

Excellent comments from Okefenokee Swamp Park, requesting at least three public hearings by the Army Corps, plus independent research, in addition to a full Environmental Impact Statement. When I received them from Dr. Clark last night, he asked me to circulate them widely; see also PDF.
