SUPPLEMENTARY INFORMATION: The Lisbon Valley Copper Mine is in the
Lisbon Valley in San Juan County in southeast Utah. The mine, situated
on Federal, State, and private lands, has been in operation under the
ownership of multiple companies since 1998. LVMC has operated the mine
under Plan of Operations Serial No. UTU 072499 (mine plan) since it
obtained ownership in 2009. The mine plan boundary encompasses 4,480
acres, of which current operations cover 1,146 acres (BLM: 521 acres;
State: 333 acres; and private: 292 acres) of disturbance. LVMC also
conducts exploration activities within a 5,430-acre authorized boundary
adjacent to the mine plan boundary under Exploration Plan of Operations
Serial No. UTU 077879 (exploration plan). Federal, State, and private
lands occur within the exploration plan boundary (BLM: 3,199 acres;
State:1,056 acres; and private: 1,175 acres).
LVMC currently mines copper ore at the mine from mineralized zones
in porous sandstones approximately 50 to 200 feet below the surface
using conventional open pit mining methods. Waste rock material is
hauled to existing waste rock storage areas or is used to backfill
existing pits. The copper ore is hauled to a heap leach facility where
it is crushed and stacked onto a heap leach pad. A low pH solution is
sprayed onto the crushed ore and copper is leached out of the rock into
solution. The resultant copper-laden solution is sent to adjacent
process facilities where it undergoes solvent extraction and
electrowinning processing. The final product is copper cathode of a
99.9% purity. Currently, LVMC is mining copper ore from two open pits.
LVMC expects to operate the current mine until both pits are exhausted
in approximately 2028.
On April 11, 2023, the BLM Moab Field Office received a proposal
from LVMC to modify its current mine plan. Consistent with the surface
management regulations at 43 CFR 3809.411(a), the BLM reviewed the
filed plan of operations modification and accepted it as complete on
May 5, 2023.
Purpose and Need for the Proposed Action
The BLM's purpose and need are to respond to LVMC's mine plan
modification proposal to expand mining operations and associated
infrastructure and to prevent unnecessary and undue degradation of the
public lands consistent with the BLM's responsibilities under FLPMA,
surface management regulations (43 CFR subpart 3809), and use and
occupancy regulations (43 CFR subpart 3715).
Preliminary Proposed Action and Alternatives
The proposed action is to modify the mine plan to expand open pit
mining and beneficiation operations and to initiate the extraction of
copper through a method of in-situ recovery (ISR) mining. The proposed
expansion activities would include improvement of existing mining
facilities in the mine plan boundary and construction of new facilities
and associated access, power, and water facilities in the exploration
plan boundary. Under the proposed action there would be approximately
2,391 acres of new surface disturbance (BLM: 1,388 acres; State: 412
acres; and private: 591 acres). Reclamation would be ongoing through
the different phases of mining. The life of the mine is anticipated to
be 20 years with final reclamation and post-closure monitoring
occurring until approximately 2066.
The mine plan modification would include the following components:
open pit, backfill area, ISR wellfield (injection wells, pump-back
wells, and monitor wells), waste rock storage, storm water diversion
channels, sediment basins, berms, heap leach pad, process ponds,
solution pipelines, access roads, and ancillary facilities (power
supply; reagent, fuel, ready line; crushing area and related
stockpiles; area for temporary storage of petroleum-contaminated soils;
groundwater monitoring wells; water supply pipeline and facilities; and
construction laydown yards).
The proposed disturbance also includes improvements to the existing
mining and processing facilities and their associated roads in the mine
plan
[[Page 46156]]
boundary to accommodate the increase in copper production and personnel
on site. Ongoing mining activity would continue in the existing mine
plan boundary as LVMC constructs the proposed new facilities, which are
expected to be completed within three years.
The installation of ISR wellfields would occur in conjunction with
open pit mining operations. ISR activities would include the
construction of access roads and approximately 1,700 well pads for
injection, production, and/or monitoring that would each be 50 feet by
50 feet in size and spaced approximately 125-200 feet apart. LVMC would
install the first injection and production wells in an existing pit
area for a pilot test for the ISR. The pilot test at the existing pit
area would last approximately one year. At the end of the pilot test,
the data derived would be used to fine-tune the installation of the ISR
wellfield, which would be adjacent to the new open pit. ISR mining
would occur for the life of the mine until final reclamation.
In accordance with 40 CFR 1502.14(e), the BLM will develop
alternatives to the proposed action in response to resource concerns
and public scoping input. Resource concerns likely to influence
alternatives development include water and waste management (e.g.,
waste rock and tailings). One preliminary alternative identified at
this stage is the proposed action without ISR mining. The BLM welcomes
comments on all preliminary alternatives as well as suggestions for
additional alternatives.
Summary of Expected Impacts
Surface and subsurface disturbances associated with open-pit and
ISR mining techniques may result in impacts to cultural, biological,
visual, and water resources (surface and groundwater, including
drinking water). Mining activities would also result in emissions of
air pollutants and greenhouse gases.
Anticipated Permits and Authorizations
The following permits and authorizations are anticipated to be
required to proceed with the proposed action:
<bullet> BLM authorization of the modification to the Plan of
Operations Serial No. UTU 072499. (The total acreage of the exploration
plan boundary would be reduced commensurate with the total exploration
plan area that would get subsumed in the mine plan area.)
<bullet> U.S. Environmental Protection Agency authorization of an
Aquifer Exemption (Class III Wells) Permit.
<bullet> State of Utah, Department of Environmental Quality
authorization of Class III and Class V Underground Injection Control
Permits, Utah Pollutant Discharge Elimination System Industrial
Stormwater Permit (UTR00737), Ground Water Discharge Permit
(UGW370005), Approval Order for Emissions Source (DAQE-AN114620014).
<bullet> State of Utah, Department of Natural Resources
authorization of a Large Mining Permit (M/037/0088), Reclamation
Contract (M/037/0088), Exploration Permit (E/037/0115), and Water
Rights 05-2593; 05-762.
<bullet> San Juan County, Utah authorization of a Conditional Use
Permit and a Building Permit.
Schedule for the Decision-Making Process
The BLM will provide additional opportunities for public
participation consistent with the NEPA process, including a 45-day
comment period on the draft EIS. The draft EIS is anticipated to be
available for public review in the winter of 2025, and the final EIS is
anticipated to be released in the spring of 2026 with a record of
decision also in the spring of 2026.
Public Scoping Process
This notice of intent initiates the scoping period. The BLM will be
holding one in-person public scoping meeting in Moab, Utah, and one
virtual public scoping meeting. The specific dates and locations of
these scoping meetings and any additional scoping meetings will be
announced in advance through the BLM Moab Field Office website (<a href="https://www.blm.gov/office/moab-field-office">https://www.blm.gov/office/moab-field-office</a>), BLM social media, and on the
BLM e-Planning page (see ADDRESSES).
Lead and Cooperating Agencies
The lead agency is the BLM. During the scoping process the BLM will
invite other Federal, State, and local agencies with special expertise
and/or jurisdiction by law to participate as cooperating agencies in
the preparation of the EIS. Tribal nations will also be invited to
participate as cooperating agencies.
Responsible Official
The responsible official for the BLM is the BLM Utah State
Director. The scope of the State Director's decision is limited to the
modification to the Plan of Operations Serial No. UTU 072499.
Nature of Decision To Be Made
The BLM will decide whether to authorize modifications to LVMC's
mine plan of operations and, if so, under what terms and conditions.
Additional Information
The BLM will identify, analyze, and consider mitigation to address
the reasonably foreseeable impacts to resources from the proposed
action and all analyzed alternatives and, in accordance with 40 CFR
1502.14(e), include appropriate mitigation measures not already
included in the proposed action or alternatives. Mitigation may include
avoidance, minimization, rectification, reduction or elimination over
time, and compensation; and it may be considered at multiple scales,
including the landscape scale.
The BLM will utilize and coordinate the NEPA process to help
support compliance with applicable procedural requirements under the
Endangered Species Act (16 U.S.C. 1536) and section 106 of the National
Historic Preservation Act (54 U.S.C. 306108) as provided in 36 CFR
800.2(d)(3), including public involvement requirements of Section 106.
The information about historic and cultural resources and threatened
and endangered species within the area potentially affected by the
proposed project will assist the BLM in identifying and evaluating
impacts to such resources.
The BLM will consult with Tribal nations on a government-to-
government basis in accordance with Executive Order 13175, BLM Manual
Section 1780, and other Department of the Interior policies. Tribal
concerns, including impacts on Indian trust assets and potential
impacts to cultural resources, will be given due consideration.
Federal, State, and local agencies, along with Tribal nations and other
stakeholders that may be interested in or affected by the proposed
project that the BLM is evaluating, are invited to participate in the
scoping process and, if eligible, may request or be requested by the
BLM to participate in the development of the environmental analysis as
a cooperating agency.
