Notice of Availability of the Draft Environmental Impact
Statement for the Proposed Marigold Mining Company--Marigold Mine--
Mackay Optimization Project Humboldt County, Nevada
AGENCY: Bureau of Land Management, Interior.
ACTION: Notice of availability.
-----------------------------------------------------------------------
SUMMARY: In accordance with the National Environmental Policy Act of
1969, as amended (NEPA), and the Federal Land Policy and Management Act
of 1976, as amended, the Bureau of Land Management (BLM) Humboldt River
Field Office, Winnemucca,
[[Page 22895]]
Nevada has prepared a Draft Environmental Impact Statement (EIS) for
the Proposed Marigold Mine--Mackay Optimization Project (Project) and
by this notice is announcing the opening of the comment period.
DATES: This notice initiates the public comment period for the Draft
EIS. Comments may be submitted in writing until July 5, 2019. The
date(s) and location(s) of any comment meetings will be announced at
least 15 days in advance through local media, newspapers and the BLM
website at: http://1.usa.gov/1PKqIbI. In order to be included in the
Draft EIS, all comments must be received prior to the close of the 45-
day public comment period. We will provide additional opportunities for
public participation upon publication of the Final EIS.
ADDRESSES: You may submit comments related to the Marigold Mine--Mackay
Optimization Project by any of the following methods:

SUPPLEMENTARY INFORMATION: The applicant, Marigold Mining Company
(MMC), a wholly-owned subsidiary of SSR Mining Inc., has requested to
optimize and modify its approved Plan of Operations by expanding its
gold mining operations at the existing Marigold Mine, which is located
in the southeastern portion of Humboldt County, Nevada approximately 35
miles southeast of Winnemucca. The mine is currently authorized to
disturb up to 5,682.6 acres (3,211.4 acres of private land and 2,471.2
acres of public land), and was permitted under a series of
Environmental Impact Statements and Environmental Assessments from July
1988 through October 2013.
All proposed disturbance would occur within the existing approved
Plan boundary and includes combining multiple existing pits into three
large pits. Waste rock storage areas, heap leach pads, and other
supporting facilities would be expanded to support the pit expansion.
The pits are proposed to extend below the historic water table
necessitating dewatering of the groundwater and rapid infiltration
basins (RIBs) for recharging the excess water downgradient of the pits.
If approved, the proposed modification would extend the mine life by up
to 10 years.
Amendments to two associated rights-of-ways (ROWs) needed to
accommodate the proposed mine changes are evaluated in the Draft EIS.
These ROWs include relocation of a portion of the county road called
Buffalo Valley Road and of a portion of the existing 120-kV power line
(ROW held by NV Energy).
The Draft EIS analyzes three alternatives; the Proposed Action,
Alternative I--Partial Discharge to Cottonwood Creek and Pipeline to
RIBs Alternative, and the No Action Alternative.
The Proposed Action, if selected by the BLM, would include 2,055.9
acres of new disturbance (800.9 acres of public land and 1,255 acres of
private land), increasing the surface disturbance by a total of 7,738.5
acres (3,271.7 acres of public land and 4,466.4 acres on private land).
Under Alternative I, all components of the Proposed Action would be
the same except for the proposed dewatering operation that would
increase the total disturbance by approximately 4 acres. A portion of
the dewatered groundwater (approximately 191 gpm) would be treated at a
water treatment plant, transported via an above ground pipeline system
and discharged to Cottonwood Creek drainage, creating a water source
for livestock and wildlife while recharging the aquifer. The remaining
portion of dewatering water would be piped to the RIBs.
Under the No Action Alternative, the plan modification would not be
authorized and the activities described under the Proposed Action would
not occur. MMC would continue mining activities as authorized in their
current Plan, dated November 6, 2013, with closure in 2027, followed by
approximately three years of reclamation.
A Notice of Intent (NOI) to prepare an EIS for the proposed Mackay
Project was published in the Federal Register on March 4, 2016 (FR Doc
No: 2016-04806). The BLM received 22 public scoping comment during the
31-day scoping period. From the 22 comments, 70 issue statements were
identified and evaluated in the Draft EIS (Table 1.4-1). The following
issues of environmental, social, and economic concern were identified:
Air quality from mining emissions; fugitive dust; hazardous air
pollutants; greenhouse gases; geochemical concerns from mining
activities; effects on cultural sites; impacts to California Trails;
environmental justice; Native American Religious Concerns; noise
effects on Greater Sage Grouse and humans; rangeland management;
impacts from the relocation of county road and NV Energy powerline;
public access for dispersed recreation; economic benefits; visual
resources; surface and groundwater quality and quantity impacts due to
dewatering of the aquifer; water rights; formation of a pit lake with
evaporative water losses; wetland and riparian zones; wildlife impacts
due to mining activities (vegetation loss, weed management, surface
water sources, migration routes, lighting); environmental protection
measures; mitigation; monitoring; reclamation; closure; and
alternatives.
The BLM analyzed a combination of proposed environmental measures
and possible mitigation to eliminate or minimize impacts associated
with the proposed action. These included the potential for identifying
opportunities to apply mitigation hierarchy strategies for on-site and
regional mitigation appropriate to the size of the proposal, and
management actions to achieve resource objectives.
The BLM will use NEPA public participation requirements to assist
the agency in satisfying the public involvement requirements under the
National Historic Preservation Act (NHPA) (54 U.S.C. 306108) pursuant
to 36 CFR 800.2(d)(3). The information about historic and cultural
resources within the area potentially affected by the proposed
amendment will assist the BLM in identifying and evaluating impacts to
such resources in the context of both NEPA and the NHPA.
The BLM continues to consult with Indian tribes on a government-to-
government basis in accordance with Executive Order 13175 and other
policies. Tribal concerns, including impacts to Indian trust assets and
potential impacts to cultural resources, will be given due
consideration. Federal, State, and local agencies, along with tribes
and other stakeholders that may be interested or affected are invited
to comment on the proposal that the BLM is evaluating.
