Notice of Availability of the Cyprus Tohono Corporation Proposed
Mine Expansion Final Environmental Impact Statement, Phoenix District,
Arizona
AGENCY: Bureau of Land Management, Interior.
ACTION: Final environmental impact statement.
-----------------------------------------------------------------------
SUMMARY: In compliance with the Federal Land Policy and Management Act
of 1976, section 102(2)(c) of the National Environmental Policy Act of
[[Page 20738]] 1969, and The United States Department of the Interior
Secretarial Order No. 3087, Section 5, Amendment No. 1, The Bureau of
Land Management (BLM) has prepared an Environmental Impact Statement
(EIS) for the Cyprus Tohono Corporation's (Cyprus) proposed mine
expansion on the Tohono O'odham Nation (Nation), Papago Indian
Reservation. The proposed action (Alternate B) consists of the
conversion from in situ to open pit mining operations at Cyprus, the
creation of a new overburden storage site, and a new copper oxide ore
heap leach pad. Cyprus proposes production of approximately one billion
pounds of copper during the thirteen year life of the proposal. A
description of existing facilities and a detailed proposed plan of
operations is presented in the Mine Plan of Operations for Expanded
Open Pit and Heap Leach Operation (Cyprus Tohono Corporation, March
1995). The project was developed in response to three underlying needs:
Mining lease compliance, continued industrial economic support for the
Nation, and copper production.
Implementation of Alternative B would result in the disturbance of
a total of approximately 1,850 acres, or approximately 0.06 percent of
total Nation lands. Alternative B Mine Plan of Operations involves the
development, operation, performance and maintenance of the following
major project components: Open pit mine expansion, overburden disposal
area, heap leach pads and ponds, stormwater collection and recycling,
processing facilities, access and service roads, support facilities,
utilities, spill prevention, control health and safety plans,
reclamation and closure. There would be increases in royalties and
employment. Scholarships would be established. Each of the major
project components are described in the main body of the EIS.
Alternative B Mine Plan of Operations was developed to minimize
potential impacts to biological and visual resources. Alternative B
Mine Plan of Operations moved some of proposed mine components south of
an existing access road. Movement of the proposed project elements
south of the existing mine access road serves to limit disturbance of
natural drainages, reduce potential disturbance to bat colonies north
of the site, and to provide a visual screen of existing mine plant site
structures.
DATES: Appeals must be filed within 30 days of the Notice of Filing by
the United States Environmental Protection Agency in the Federal
Register. These procedures can be found in the Code of Federal
Regulations (43 CPR 1610.5-2).
SUPPLEMENTARY INFORMATION: A limited number of copies of the Final EIS
are available upon request to the: District Manager, Phoenix District
Office, Bureau of Land Management, 2015 West Deer Valley Road, Phoenix,
Arizona 85027. There are also copies available for review at the above
location.
