Environmental Impact Statement

AGENCY: Forest Service, USDA.

ACTION: Notice of intent to prepare an environmental impact statement 
for approval of a mining plan of operations for the Pinto Valley Mine, 
notice of public scoping, and request for scoping comments.

-----------------------------------------------------------------------

SUMMARY: The Tonto National Forest (TNF) is preparing an Environmental 
Impact Statement (EIS) to evaluate and disclose the potential 
environmental effects from approval of the Mining Plan of Operations 
(MPO) submitted by Pinto Valley Mining Corp. (PVMC), for operations on 
National Forest System (NFS) land associated with expansion of an 
existing open pit copper and molybdenum mine, the Pinto Valley Mine. An 
amendment to the Tonto National Forest Land and Resource Management 
Plan (Forest Plan, 1985, as amended) may be required.

DATES: Comments concerning the scope of the analysis must be received 
no later than April 27, 2017. Public scoping meetings will be held on 
April 18 at Superior Junior/Senior High School, 100 Mary Drive, 
Superior, Arizona and April 20 at Miami Junior/Senior High School, 4739 
S. Ragus Rd., Miami, Arizona from 5:00 to 8:00 p.m.

SUPPLEMENTARY INFORMATION: PVMC submitted the proposed MPO for approval 
by the Forest Service in May 2016. The proposed MPO was submitted in 
accordance with Forest Service

[[Page 15323]]

regulations for locatable minerals set forth at Title 36 of the Code of 
Federal Regulations (CFR), part 228 (36 CFR part 228), subpart A, 
Locatable Minerals.
    The proposed action would consolidate prior permitted activities 
reasonably incident to extraction, transportation, and processing of 
copper and molybdenum on NFS lands and expand existing mining 
operations from private lands on to NFS lands primarily for tailings 
disposal and pit expansion.

Purpose and Need for Action

    The purpose of this project is to analyze the proposed action as 
required by the regulations at 36 CFR 228.5(a). Approval of the 
proposed MPO would be a major federal action subject to National 
Environmental Policy Act of 1969 (NEPA). Accordingly, the Forest 
Service must prepare an EIS to identify the scope of issues associated 
with the MPO, identify and assess reasonable alternatives to the MPO in 
order to avoid or minimize adverse effects of MPO actions and evaluate 
and disclose the potential environmental effects. An amendment to the 
Tonto National Forest Land and Resource Management Plan (Forest Plan, 
1985, as amended) may be required.
    The need for this project is to comply with the regulations of the 
Forest Service, Department of Agriculture, that govern the use of 
surface resources in conjunction with mining operations on NFS lands as 
set forth under 36 CFR part 228. These regulations require that the 
Forest Service respond to parties who submit proposed mining plans for 
approval to conduct mining operations on or otherwise use NFS lands in 
conjunction with mining for part or all of their planned actions. In 
accordance with regulations at 36 CFR 228.5, the submittal of the 
proposed MPO by PVMC requires the Forest Service to consider whether to 
approve the proposed MPO or to require changes or additions deemed 
necessary to meet the purpose of the regulations for locatable mineral 
operations at 36 CFR part 228, subpart A. Forest Service cannot 
categorically prohibit mining operations that are reasonably incident 
to mining of locatable minerals on NFS lands in the area of the 
proposed action.

Proposed Action

    The proposed action is to approve the MPO as submitted by PVMC. 
Pinto Valley Mine expansion would affect federal lands administered by 
TNF and private lands owned by PVMC. The proposed action by the Forest 
Service would only approve mining operations on NFS lands, since the 
Forest Service does not have jurisdiction to regulate mining operations 
that occur on private land. However, the EIS will consider and disclose 
environmental effects associated with the MPO. Connected actions 
related to the MPO and potential amendment of the forest plan, if 
required, would be analyzed in the EIS. Impacts from past, present, and 
reasonably foreseeable future actions will be considered in combination 
with impacts of the proposed project to estimate potential cumulative 
impacts.

Existing and Proposed Mining Operations

    Pinto Valley Mine is an existing open pit copper and molybdenum 
mine with adjacent milling and processing operations, tailings disposal 
areas, and waste rock disposal, all operated by PVMC. The majority of 
Pinto Valley Mine is located on PVMC property. However, certain 
facilities and operations are located on TNF, and were authorized by 
the Forest Service or the U.S. Department of Interior, Bureau of Land 
Management (BLM) through Rights-of-Way, Plans of Operations, Special 
Use Permits, and a Letter Agreement. The authorizations date from as 
early as the 1940s, and have been amended, updated, and re-authorized 
over the years.
    Existing surface disturbance associated with the Pinto Valley Mine 
currently encompasses an estimated 3,845 acres, of which 3,389 acres 
are on private and 456 acres are on NFS lands. The proposed disturbance 
acreage would be an additional 1,011 acres of surface disturbance (766 
acres on private land, 245 acres on NFS lands) for a total estimated 
surface disturbance of 4,856 acres (4,155 on private land, 701 acres on 
NFS lands).
    Each of the past, present, and proposed future uses of NFS lands is 
addressed in the MPO. Existing or proposed mining use of NFS lands 
includes portions of the Open Pit, 19 Dump, portions of three tailings 
storage facilities, transportation on Forest Roads and temporary access 
roads, use of existing powerlines and water pipelines, existing water 
supply, stormwater management facilities, and a sign.
    In summary, at the end of the current planned life of the mine, 
PVMC would use approximately 701 acres of NFS lands and 42.45 miles of 
Forest Roads and temporary access roads to access mine facilities and/
or as alignments for linear utility infrastructure.

Possible Alternatives

    The Pinto Valley Mine EIS will analyze the No Action Alternative, 
which would not approve of the proposed MPO. For the No Action 
Alternative, mining operations, reclamation, and closure would continue 
under current authorizations. The responsible official does not have 
discretion to select the No Action alternative, because it would not be 
consistent with requirements of 36 CFR 228.5.
    The EIS may evaluate additional alternatives that could include 
application of design features and other measures that address issues 
identified during scoping, that would meet the purpose and need for the 
project, and are reasonable and practicable. These alternatives may 
require changes to the proposed MPO, which are necessary to meet Forest 
Service regulations for locatable minerals set forth at 36 CFR part 
228, subpart A.

Lead and Cooperating Agencies

    The Forest Service will be the lead agency preparing the EIS. 
Cooperating agencies have not yet been confirmed, but may include 
agencies within the Department of the Interior, as well as other state 
and Federal agencies with regulatory and/or enforcement jurisdiction 
over the project.

Responsible Official

    The Forest Supervisor of the TNF will be the responsible official 
who prepares the Record of Decision (ROD) and approves the MPO.

Nature of Decision To Be Made

    TNF Forest Supervisor will consider beneficial and adverse impacts 
of each alternative analyzed in the EIS. TNF Forest Supervisor has 
discretion to determine whether changes in the proposed MPO will be 
required prior to approval.

Plan of Operations

    Using the analysis in the EIS and supporting documentation, the TNF 
Forest Supervisor will make the following decisions regarding the 
proposed MPO:
    1. Decide whether to approve the proposed MPO submitted by PVMC, or 
require changes in, or additions to, the proposed MPO to meet the 
purpose of the regulations, including those for environmental 
protection and reclamation set forth at 36 CFR part 228, subpart A 
before approving a final MPO. The alternative that is selected for 
approval in the final MPO must minimize adverse impacts on NFS surface 
resources where feasible.
    2. If Forest Service determines that any amendment(s) is (are) 
required to the Forest Plan, then decide whether to approve amendments 
to the Forest Plan,

[[Page 15324]]

which would be necessary to approve the final MPO.

Final EIS and Record of Decision

    The Forest Supervisor plans to release a draft ROD in conjunction 
with the final EIS. The draft ROD would address the decision on 
approval of the MPO. The decision would be subject to 36 CFR part 218, 
Project-Level Pre-decisional Administrative Review Process. If forest 
plan amendments are required, then the draft decision may also be 
subject to 36 CFR part 219, subpart B, Pre-decisional Administrative 
Review Process.
    Following resolution of objections to the draft ROD, a final ROD 
would be issued. PVMC would have an opportunity to appeal the decision 
as set forth at 36 CFR part 214, Postdecisional Administrative Review 
Process for Occupancy or Use of National Forest System Lands and 
Resources.
    Prior to approval of the MPO, PVMC may be required to modify the 
proposed MPO to align it with the description of the selected 
alternative in the final ROD. In addition, the TNF Forest Supervisor 
would require PVMC to submit a reclamation bond or other acceptable 
financial assurance to ensure that NFS lands and resources involved 
with the mining operation are reclaimed in accordance with the approved 
MPO and Forest Service requirements for environmental protection (36 
CFR 228.8 and 228.13). After the Forest Service has determined that the 
MPO conforms to the ROD and that the reclamation bond is acceptable, 
the TNF Forest Supervisor would approve the MPO. Implementation of 
mining operations that affect NFS lands and resources may not commence 
until the MPO is approved and the reclamation bond or other financial 
assurance is in place.

Preliminary Issues

    Issues to be analyzed in the EIS will be developed during the 
scoping process. Preliminary issues expected to be analyzed include 
potential impacts to: Groundwater and surface water quantity and 
quality; riparian and aquatic areas and springs; biological resources, 
including threatened and endangered species and Forest Service 
sensitive species; historical and cultural resources; air quality; 
socioeconomics; transportation and traffic; noise; visual resources; 
and recreation. This list is subject to change based on comments 
received from the public and resource agencies.

Permits or Licenses Required

    The following is a list of permits for Pinto Valley Mine: Permits 
associated with groundwater withdrawal and dam safety permits (Arizona 
Department of Water Resources); air quality Class II synthetic minor 
permit (Arizona Department of Environmental Quality), Arizona Pollutant 
Discharge Elimination System process and stormwater permits, Aquifer 
Protection Permit, and public water supply permit (Arizona Department 
of Environmental Quality); Mined Land Reclamation Plan (Arizona State 
Mine Inspector); letter agreement for a commercial vehicle staging area 
(Arizona Department of Transportation); and other required permits. 
Because the Pinto Valley Mine is an operating mine, PVMC already holds 
required permits. PVMC would update and amend permits for additional 
activities proposed in the MPO, as required.

Scoping Process

    This notice of intent initiates the scoping process, which guides 
the development of the Pinto Valley Mine EIS. Public comments may be 
submitted to TNF in a variety of ways, including: By email, via the 
project Web site, by mail, and by facsimile. In addition, TNF will 
conduct two open houses during the scoping process through which 
members of the public can learn about the proposed action and the NEPA 
review process, and submit comments. Comments sought by TNF include 
specific comments related to the proposed action, appropriate 
information that could be pertinent to the description of baseline 
resource conditions and analysis of environmental effects, 
identification of significant issues, identification of reasonably 
foreseeable actions that should be considered in the cumulative 
analysis, and identification of potential design features and 
alternatives.
