New rare earth plant will increase pollution impacts

In 2025, Element USA proposed a plan to reprocess bauxite waste from the ATALCO alumina plant in Gramercy to derive rare earth minerals for the US military. The ATALCO facility is well known for its lax air pollution controls over its long operational history, and the toxic dust is plainly visible staining all of the plant operations buildings a deep red. In addition, the toxic dust is regularly carried by winds to powder homes, gardens and vehicles over a mile from the plant operations. Last year, the bauxite mud lake dams failed, and the slurry waste was leaching toxins into the wetlands north of the site. The construction of a new waste re-processing plant would generate a whole new set of environmental concerns for an already dirty industry that has poor credibility for pollution controls.

Solution

Cartographic regression using archival maps from 1877

The 1877 US Coast Survey, commissioned after the Civil War, contains a wealth of information about features of the landscape along the Mississippi. The surveyors took detailed notes of the landscape, including predominant crops grown, built structures, and very importantly, the locations of human burial sites that are otherwise not registered or well documented on other maps. This archival map has become the go-to resource for discovering important archaeological site information, and locating in the current day using a process of image transpositions and overlays called “cartographic regression”. Field archaeology work is then conducted to confirm locations, the results of which will be published in a Cultural Resources Survey, which is required prior to any ground disturbance for proposed new construction. The 1877 map reveals that there are at least three burial sites within the boundary of the ATALCO property (see Image 1 and 2). This is partially confirmed by a recent subdivision application submitted by the property owner to St James parish planning commission (see Image 3).
