The BLM announces public comment period for proposed Mosaic Potash operations brine management system project

CARLSBAD, N.M. – The Bureau of Land Management (BLM) Carlsbad Field Office is announcing a 30-day public comment period beginning June 21, 2021, on the environmental assessment (EA) for the Mosaic Potash Carlsbad, Inc.’s proposed tailings management system in Eddy County, N.M.  

The BLM received an application to modify the proponent’s mine plan of operations on Federal lands for the proposed tailings management system. The modification request includes an interest in utilizing the Laguna Uno as a secondary settling area on an increased basis to assist in clarifying the brine tailings discharge.  

“Review and comment periods provide an opportunity for the public to inform the BLM of any concerns they have regarding a proposed project,” said acting BLM Carlsbad Field Manager Dave Evans. “Please keep in mind that substantive, factual-based comments are the most helpful.” 

The draft EA and additional project details are available online at: Comments can be submitted via ePlanning or by mail to BLM Carlsbad Field Office, Attn: Robert Salaz, 620 E. Greene St., Carlsbad, NM 88220. The comment period closes on July 23, 2021.
