SUPPLEMENTARY INFORMATION:
I. Introduction
By letter dated December 11, 2017 (ADAMS Package Accession No.
ML17361A006), Homestake Mining Company of California (HMC or the
licensee) requested NRC approval of HMC's license amendment to modify
its License No. SUA-1471, Condition 35. The request includes the
addition of a zeolite water treatment system for the removal of low
levels of uranium from contaminated groundwater as part of the approved
groundwater corrective action program (CAP) at the Grants Reclamation
Projects site. The CAP is authorized under NRC License No. SUA-1471,
Condition 35.C and is implemented using an adaptive, ongoing strategy
that includes monitoring, water management, water treatment, and source
control. The Grants Reclamation Project site is located near Milan, New
Mexico and is owned and operated by HMC. The NRC staff has prepared an
EA (ADAMS Accession No. ML19263C623) as part of its review of this
proposed action in accordance with the requirements in part 51 of title
10 of the Code of Federal Regulations (10 CFR), ``Environmental
Protection Regulations for Domestic Licensing and Related Regulatory
Functions'' and associated staff guidance. The NRC has concluded that
the proposed action will not have a significant effect on the quality
of the human environment.
II. Summary of the Environmental Assessment
Description of the Proposed Action
The proposed action is to review and approve the request for
modification of the CAP by amending License No. SUA-1471, Condition 35,
to add the 300 gpm and 1200 gpm zeolite water treatment systems to
increase the water treatment capacity. Pilot testing of the zeolite
water treatment systems was performed by the licensee to verify the
effectiveness of the treatment system in order to accelerate the
groundwater restoration. As part of the pilot test, the 300 gpm and
1200 gpm zeolite treatment systems were installed and are currently in
use.
Need for the Proposed Action
By letter dated December 11, 2017, the licensee notified the NRC of
its proposal to formally add zeolite groundwater treatment systems to
its CAP. Expanded groundwater treatment capacity is needed to
accelerate groundwater restoration at the Grants site. Use of the
zeolite water treatment system, in addition to reverse osmosis, will
allow HMC to meet its NRC-mandated water remediation goals.
Environmental Impacts of the Proposed Action
The NRC staff evaluated the potential environmental impacts
associated with the proposed action and has performed its environmental
review in accordance with the requirements in 10 CFR part 51 and
associated staff guidance. As detailed in the EA, the staff reviewed
relevant information submitted by the licensee and consulted with the
New Mexico State Historic Preservation Office (NMSHPO), the Hopi of
Arizona, Navajo Nation, Pueblo of Acoma, Pueblo of Isleta, Pueblo of
Laguna, and Pueblo of Zuni. The NRC staff, with the assistance of the
U.S. Fish and Wildlife Service (USFWS) Information for Planning and
Consultation (IPaC) project planning tool, determined that the listed
species and/or critical habitat would not be adversely affected by the
proposed action. Additionally, a draft EA was shared with New Mexico
Environment Department (NMED).
During the pilot study, HMC constructed the 300 gpm and 1200 gpm
zeolite systems in a previously and highly disturbed area within the
licensed site boundary, and no further activities involving land
disturbance are planned. Therefore, the NRC staff considers that there
would be no impacts on the following resources areas: land use, geology
and soils, water resources, ecology, meteorology, climate, air quality,
noise, transportation, waste management, visual and scenic resources,
and socioeconomic resources.
The NRC staff evaluated the radiological impacts on workers and the
public. The staff found that the radiological doses to workers would be
within the dose limits specified in 10 CFR 20.1201, ``Occupational dose
limits to adults,'' and that radiological doses to the public would be
indistinguishable when compared to background radiation.
The NRC staff also evaluated the cumulative impacts by identifying
past, present, and reasonably foreseeable future actions at the Grants
site, and the incremental impacts of HMC's proposed action. The staff
determined that the proposed action would not significantly contribute
to cumulative impacts. The staff also determined that the proposed
action would not affect federally listed endangered or threatened
species or their critical habitats, if present.
Environmental Impacts of the Alternatives to the Proposed Action
The NRC staff considered a no-action alternative for this EA. Under
the no-action alternative, the NRC staff could deny HMC's request to
add the zeolite water system at its Grants site. However, because HMC
is using the zeolite system under a pilot test, the NRC considers the
environmental impacts of this alternative to be similar to those of the
proposed action. Therefore, staff concluded that denying the addition
of the zeolite systems to HMC's license is not a reasonable
alternative.
Agencies and Persons Consulted
In August 2018, the NRC staff accessed the USFWS IPaC online
project planning tool and determined that, while there was potential
for some threatened or endangered species to be present in the general
area, there is no critical habitat at the project location. Therefore,
the NRC has determined that no further consultation with the USFWS is
required under Section 7 of the Endangered Species Act. By letter dated
[[Page 67482]]
October 31, 2018 (ADAMS Package Accession No. ML18267A257), the staff
consulted with the New Mexico Department of Game and Fish (NMDGF) and
asked them to concur with the determination that the proposed action
was not the type to affect threatened or endangered species or their
critical habitats, assuming they were present. The NMDGF replied by
letter dated December 3, 2018 and indicated that, in 2016, a dozen
migratory bird fatalities occurred at one of the evaporation ponds on
the Grants site. As a follow-up to their response the NRC staff called
the NMDGF to clarify that the pond in question is not part of the
current licensing action and that the NRC would on their recommendation
contact the USFWS. In March 2019, the NRC spoke with the USFWS to
better understand whether their concerns extended to threatened and
endangered species. During that call, the USFWS indicated that in 2016
they contacted HMC and provided suggestions for preventing migratory
bird deaths. The contact at USFWS Region 2 is unaware of additional
migratory bird deaths or whether threatened or endangered species were
included among the dead birds at the Grants site.
Section 106 of the National Historic Preservation Act of 1966, as
amended, requires federal agencies to consider the effects of their
undertakings on historic properties. The NRC's approval of this license
amendment request constitutes a federal undertaking. However, the NRC
staff has determined that the scope of activities described in this
license amendment request do not have the potential to cause effects on
historic properties, assuming those were present, because the NRC's
approval of this license request will not result in construction or
land disturbance activities.
The NRC staff also consulted with the NMSHPO by letter dated
September 21, 2018 (ADAMS Accession No. ML18232A151). The NMSHPO
responded by email dated October 16, 2018, stating that they agreed
with a finding of no adverse effect for the proposed action and also
recommended by letter dated November 13, 2018, that the NRC consult six
Tribes: Hopi of Arizona, Navajo Nation, Pueblo of Acoma, Pueblo of
Isleta, Pueblo of Laguna, and Pueblo of Zuni (ADAMS Package Accession
No. ML18233A143). By letter dated November 13, 2018, the NRC sent a
consultation letter to the six Tribes explaining the activities
involved in the proposed action and the preliminary determination of no
potential to effect historic properties, assuming they were present.
In July 2019, the NRC provided the NMED with the opportunity to
review the draft EA (ADAMS Accession No. ML19196A071) and requested
NMED input. On August 12, 2019 the NMED responded by email (ADAMS
Accession No. ML19225B308) that they had reviewed the draft EA with one
comment and no other concerns with the NRC's EA findings. The NRC
addressed NMED's comment in the final EA (ADAMS Accession Number
ML19263C623).
III. Finding of No Significant Impact
In accordance with the requirements in 10 CFR part 51, the NRC
staff has concluded that the proposed action will not significantly
affect the quality of the human environment. Therefore, the staff
finds, pursuant to 10 CFR 51.31, that preparation of an environmental
impact statement is not required for the proposed action, and that a
FONSI is appropriate.
