DEPARTMENT OF AGRICULTURE
Forest Service
Tongass National Forest; Alaska; Plan of Operations Amendment 1
for the Kensington Gold Mine
AGENCY: Forest Service, USDA.
ACTION: Notice of intent to prepare a Supplemental Environmental Impact
Statement.
-----------------------------------------------------------------------
SUMMARY: In December 2018, the USDA Forest Service (Forest Service),
Tongass National Forest, received a proposal from Coeur Alaska, Inc.
(Coeur Alaska), the owner/operator of the Kensington Gold Mine (Mine),
to amend the 2005 Plan of Operations. This proposed life of mine
extension, as described in Coeur Alaska's proposed Plan of Operations
Amendment 1 (POA 1), would expand the disturbance area currently
approved by the Forest Service under the 2004 Kensington Gold Project
Final Supplemental Environmental Impact Statement (SEIS). To assess
Coeur Alaska's proposed POA 1, the Forest Service will prepare a new
SEIS. This notice advises the public that the Tongass National Forest
is gathering information necessary to prepare an SEIS to evaluate the
effects of changing the Plan of Operations via Coeur Alaska's proposed
POA 1.
DATES: Comments concerning the scope of the analysis must be received
by November 7, 2019. The Draft SEIS is expected October 2020 and the
Final SEIS is expected July 2021.
ADDRESSES: Comments may be submitted electronically at https://www.fs.usda.gov/project/?project=55533 or via facsimile to (907) 586-
8808. In addition, written comments can be delivered or mailed to:
Tongass National Forest, Kensington Gold Mine POA1 SEIS, 8510
Mendenhall Loop Rd., Juneau, Alaska 99801.
FOR FURTHER INFORMATION CONTACT: Matthew Reece, Minerals Program
Manager, Tongass National Forest at the Juneau Ranger District, 8510
Mendenhall Loop Rd., Juneau, Alaska 99801 or by telephone at (907) 586-
8800, between 8:00 a.m. and 4:00 p.m., Alaska Standard Time, Monday
through Friday.
Individuals who use telecommunication devices for the deaf (TDD)
may call the Federal Information Relay Service (FIRS) at 1-800-877-8339
between 8 a.m. and 8 p.m., Eastern Time, Monday through Friday.
SUPPLEMENTARY INFORMATION: This SEIS will tier to and incorporate by
reference the 1992 Kensington Gold Project Final EIS and the 1997 and
2004 Kensington Gold Project Final SEISs. The 2004 Final SEIS and
Record of Decision, along with other supporting documents, are
available at: https://www.fs.usda.gov/project/?project=55533.
Project Location: The Mine is located at the southern end of the
Kakuhan Range off the coastal mountains on the small peninsula formed
between Lynn Canal and Berners Bay, on the Juneau Ranger District of
the Tongass National Forest. The Mine is located about 45 air miles
northwest of Juneau, 35 air miles south of Haines, and within the
boundary of the City and Borough of Juneau, Alaska. The Mine is
accessible by passenger ferry, cargo barge, floatplane, or helicopter.
Tongass Land and Resource Management Plan (Forest Plan): The
primary land use designation in the Forest Plan for the Mine site is
Modified Landscape (to provide for natural appearing landscapes while
allowing timber harvest). The area also has an overlay designation of
Minerals (to encourage mineral exploration and development of areas
with high mineral potential).
Purpose and Need for Action
Coeur Alaska is requesting additional tailings, waste rock
disposal, and related infrastructure at the Mine to reflect positive
exploration results, improved metal prices, and ongoing operational
efficiencies. According to Coeur Alaska, these additions would allow
for continuous site operations in a safe, environmentally sound,
technically feasible, and economically viable manner, while complying
with regulatory requirements. The existing tailings and waste rock
storage is considered sufficient to provide for the Mine's needs until
2023; proposed activities would extend the mine life by 10 years until
2033. The purpose of this SEIS is for the Forest Service to consider
the proposed changes and to determine whether there is a need to amend
the Plan of Operations.
Proposed Action
Coeur Alaska has proposed POA 1 to attain a life of mine extension.
Through ongoing exploration efforts, additional ore resources have been
identified within the Kensington and Jualin deposits at the Mine. Both
deposits are currently being mined and the estimated ore production
would result in the need for additional tailings and waste rock storage
capacity. The proposal to expand the disturbance area authorized under
the approved 2005 Plan of Operations by approximately 150 acres and
achieve a life of mine extension of about 10 years includes the
following main elements:
Construction of a Stage 4 dam raise of the existing
Tailings Treatment Facility, formerly known as Lower Slate Lake,
including a causeway between the Tailings Treatment Facility and Upper
Slate Lake;
Relocation of seepage collection sumps, access road, power
line, pipelines, and stormwater diversion channels;
Expansion of three existing Waste Rock Stockpiles:
Kensington, Pit #4, and Comet;
Construction of one additional Waste Rock Stockpile
(Pipeline Road);
Relocation of ancillary facilities including the water
treatment plants at the Tailings Treatment Facility area;
Increase mill production from 2,000 tons per day to 3,000
tons per day to provide operational flexibility and make up for periods
of maintenance shutdowns; and
Construction of access roads to mitigate Slate Creek
resident fish spawning habitat losses by constructing deltas and
rerouting Fat Rat Creek into South Creek, and culvert replacements to
promote fish passage.
In general, POA 1 focuses on proposed operational changes, a new
waste rock stockpile facility, and expansions of mine facilities
presented in the 2005 Plan of Operations. If approved, POA 1 would
supersede the existing Plan of Operations where changes are proposed;
however, the approved Plan of Operations would control any items not
discussed in POA 1.
Possible Alternatives
A no-action alternative, which represents no changes to the
approved 2005 Plan of Operations and serves as the baseline for the
comparison among the action alternatives, will be analyzed in addition
to the proposed action. Comments we receive in response to this Notice
of Intent may identify additional reasonable alternatives.
Lead and Cooperating Agencies
The USDA Forest Service is the lead agency for the proposed action
and compliance with the National Environmental Policy Act. The Tongass
National Forest has identified multiple agencies with special expertise
with respect to the proposed action that could serve as cooperating
agencies. The U.S. Army Corps of Engineers has special expertise with
assessing impacts to waters of the United States, including wetlands;
additionally, a Section 404 of the Clean Water Act permit will be
needed from this agency. From the State
[[Page 49712]]
of Alaska, at least three departments could be cooperating agencies due
to their expertise and involvement in evaluations for this type of
permit application. These departments include the Alaska Departments of
Fish and Game, Environmental Conservation, and Natural Resources.
Locally, the City and Borough of Juneau could be a cooperating agency
as the Mine is within its boundaries and it issues permits for certain
facilities at the Mine. The Tongass National Forest will conduct an
effort to formally identify cooperating agencies.
Responsible Official
The responsible official for the decision on this project is the
Forest Supervisor, Tongass National Forest, Federal Building, 648
Mission Street, Ketchikan, Alaska 99901.
Nature of Decision To Be Made
The Forest Supervisor is the responsible official for this action
and will decide whether to amend the approved Plan of Operations. The
decision will be based on information that is disclosed in the Final
SEIS. The responsible official will consider the comments, responses,
disclosure of environmental consequences, and applicable laws,
regulations, and policies in deciding whether to amend the Plan of
Operations and will state the rationale for the decision in the record
of decision.
Scoping Process
This Notice of Intent initiates the scoping process, which guides
the development of the SEIS through internal and external input on the
issues, impacts, and alternatives to consider. The Forest Service will
invite the public to participate in scoping meetings in Juneau and
Haines, Alaska. These meetings will be posted on the Forest's website
at https://www.fs.usda.gov/project/?project=55533 and will be
advertised in the Juneau Empire and the Ketchikan Daily News,
newspapers of record, to announce the date, time, place, and purpose of
the public scoping meetings.
Forest Service regulations at 36 CFR 218 subparts A and B,
regarding the project-level predecisional administrative review
process, apply to projects and activities implementing land management
plans that are not authorized under the Healthy Forest Restoration Act.
Only individuals or entities who submit timely and specific written
comments concerning the project during this or another designated
public comment period established by the responsible offical will be
eligible to file on objection. It is important that reviewers provide
their comments at such times and in such manner that they are useful to
the agency's preparation of the SEIS. Therefore, comments should be
provided prior to the close of the comment period and should clearly
articulate the reviewer's concerns and contentions.
Names of commenters and comments received in response to this
solicitation will be part of the public record for this proposed
action. Comments submitted anonymously will be accepted and considered,
however, anonymous commenters will not gain standing to object as
defined in 36 CFR 218.2.
