Project Overview

The Ray Land Exchange proposes an exchange of lands between ASARCO LLC (Asarco) and the BLM for approximately 10,976 acres of “Selected” Public Lands in exchange for approximately 7,304 acres of “Offered” Private Lands. The SEIS provides additional analysis to supplement the Final Environmental Impact Statement (FEIS) issued in 1999, and is intended to  satisfy the ruling from the Ninth Circuit Court of Appeals in the case Center for Biological Diversity v. U.S. Dep’t of Interior, 623 F.3d 633 (9th Cir. 2010).
 
In accordance with the court’s ruling and remand order, the SEIS supplements the FEIS by providing a comparative analysis of the anticipated environmental impacts that could occur from the reasonably foreseeable future actions, “with and without” BLM oversight of mining activities, which was found lacking in the FEIS by the Ninth Circuit. The analysis compare two scenarios of potential environmental impacts on the Selected Lands from mining operations. One scenario analyzes potential impacts that could occur on the Selected Lands if they are not exchanged and remain under BLM jurisdiction (mining occurs with BLM regulations). The other scenario discloses potential impacts that would occur if the Selected Lands are exchanged and become privately owned lands (mining occurs without BLM regulations).
 
The SEIS also addresses any substantial changes in the land exchange and any significant new circumstances or information relevant to analyzing the impacts of the land exchange (see 40 C.F.R. § 1502.9(c); BLM NEPA Handbook § 5.3).  No new lands have been added to the proposed exchange.
