Department of Defense August 26, 2013 – Federal Register Recent Federal Regulation Documents

The U.S. Army Corps of Engineers, Los Angeles District (Corps) is examining the environmental consequences associated with the proposed construction, operation, and closure of a new tailings storage facility in eastern Pinal County, Arizona, in connection with Asarco LLC's application for a Department of the Army permit under Section 404 of the Clean Water Act. The proposed tailings storage facility and associated facilities would discharge fill materials into approximately 138 acres of waters of the U.S. and indirectly impact an additional 17 acres through dewatering. The primary federal environmental concerns are the proposed discharges of fill material into waters of the U.S. and the potential for significant adverse environmental effects resulting from such activities. Therefore, to address these concerns in accordance with the National Environmental Policy Act (NEPA), the Corps is requiring preparation of an Environmental Impact Statement (EIS) prior to consideration of any permit action. The action must comply with the Section 404(b)(1) Guidelines (40 CFR Part 230) and not be contrary to the public interest to be granted a Corps permit. The Corps may ultimately make a determination to permit or deny the above project, or permit or deny modified versions of the above project.
