Notice of Intent To Prepare an Environmental Impact Statement for
the Proposed Hyder Valley Solar Energy Project, Maricopa County, AZ
AGENCY: Bureau of Land Management, Interior.
ACTION: Notice of Intent.
-----------------------------------------------------------------------
SUMMARY: In compliance with the National Environmental Policy Act of
1969 (NEPA), as amended, the Bureau of Land Management (BLM), Arizona
State Office, Phoenix, Arizona, intends to prepare an Environmental
Impact Statement (EIS) and by this notice is announcing the beginning
of the scoping process to solicit public comments and identify issues.
DATES: This notice initiates the public scoping process for the EIS.
Comments on issues may be submitted in writing until June 21, 2010. The
date(s) and location(s) of any scoping meetings will be announced at
least 15 days in advance through local media, newspapers, and the
following BLM Web site: http://www.blm.gov/az/st/en.html. In order to
be included in the Draft EIS, all comments must be received prior to
the close of the scoping period or 15 days after the last public
meeting, whichever is later. The BLM will provide additional
opportunities for public participation upon publication of the Draft
EIS.
ADDRESSES: You may submit comments related to the Hyder Valley Solar
Energy Project by any of the following methods:
E-mail: [email protected].
Mail: Bureau of Land Management, Arizona State Office,
Attention: Eddie Arreola, Supervisory Project Manager, Hyder Valley
Solar EIS, One North Central Avenue, Suite 800, Phoenix, AZ 85004.
FOR FURTHER INFORMATION CONTACT: For further information and/or to have
your name added to our mailing list, contact Eddie Arreola, Supervisory
Project Manager, telephone 602-417-9505; by mail or other delivery
service Bureau of Land Management, Arizona State Office, Attention:
Eddie Arreola, Supervisory Project Manager, Hyder Valley Solar EIS, One
North Central Avenue, Suite 800, Phoenix, AZ 85004; or by e-mail at
[email protected].
SUPPLEMENTARY INFORMATION: The applicant, Pacific Solar Investments,
Inc., has requested a right-of-way (ROW) authorization to construct and
operate a 4,500 acre concentrated solar thermal (CST) power plant that
could provide up to 350 megawatts (MW) of solar generation with options
for wet or dry cooling and possibly with thermal storage capabilities.
The project would include a 230-kilovolt (kV) transmission line, water
supply facilities, a natural gas pipeline, an access road, and other
related facilities in the Hyder Valley, north of Interstate 8, east of
the town of Hyder, and west of the Oatman Mountains in Maricopa County,
AZ. The facility would be expected to operate for approximately 30
years. A ROW grant for the construction, operation, and maintenance of
this Project would be required from the BLM. Additional applicable
permits from Federal, State, and local agencies will also be required.
The solar facility would consist of solar fields made up of single-
axis-tracking parabolic trough solar collectors. Each collector
contains a linear parabolic-shaped reflector to focus sun light on a
heat collection element. The collectors would track the sun from east
to west each day to ensure the sun is continuously focused on the
collection element. A heat transfer fluid would be heated as it passes
through the element and then circulated through a series of heat
exchangers to generate high-pressure steam. The steam would power a
generator to produce electricity. The plant would be made up of one or
more power blocks. Each power block would be located near the center of
its respective solar field and have its own generator.
Both wet-cooled and dry-cooled options are being considered for
this Project, and will be addressed in the EIS. Maximum water use for
the Project is initially estimated to be 1,750 to 2,800 acre-feet per
year. A mechanical draft cooling tower, cooling water circulating
pumps, circulating water piping, valves, and instrumentation would also
be located within the facility. Multiple evaporation ponds would be
constructed to hold discharge from the cooling towers and steam cycle
that could no longer be recycled back into the plant.
Pacific Solar Investments is also considering the use of thermal
energy storage. Thermal energy storage would provide the option of
transferring some or all of the solar energy into molten salt contained
in insulated tanks. Using heat exchangers and pumps designed for molten
salt, the heat could subsequently be extracted to provide generation
after sunset.
The Project would be connected to the electrical grid using a newly
constructed 230-kV transmission line of approximately 5 to 7 miles long
with a point of interconnection at a proposed Hyder substation. The
proposed Hyder substation would be owned and operated by Arizona Public
Service (APS). The length of the transmission line will depend on the
exact location of the Hyder substation, which has not yet been
determined by APS. The transmission line and other related facilities
that would be developed specifically for this Project would be included
in the EIS analysis and included in the ROW grant as appropriate.
The purpose of the public scoping process is to determine relevant
issues that will influence the scope of the environmental analysis,
including alternatives, and guide the process for developing the EIS.
At present, the BLM has identified water resources as a preliminary
issue; however, the analysis will include the site-specific impacts on
air quality, geologic resources, soils, water resources, biological
resources, cultural resources, paleontological resources, visual
resources, land use, transportation, noise, socioeconomics, public
health and safety, and other resources and issues identified during
scoping and project collaboration.
The BLM will use and coordinate the NEPA commenting process to
satisfy the public involvement process for Section 106 of the National
Historic Preservation Act (16 U.S.C. 470f) as provided for in 36 CFR
800.2(d)(3). Native American tribal consultations will be conducted and
tribal concerns, including impacts on Indian trust assets, will be
considered. Federal, State, and local agencies, along with other
stakeholders that may be interested or affected by the BLM's decision
on this Project are invited to participate in the scoping process and,
if eligible, may request or be requested by the BLM to participate as a
cooperating agency.
Before including your address, phone number, e-mail address, or
other personal identifying information in your comment, you should be
aware that your entire comment-including your personal identifying
information-may be made publicly available at any time. While you can
ask us in your comment to withhold your personal identifying
information from public review, we cannot guarantee that we will be
able to do so.
Authority: 40 CFR 1501.7.
Raymond Suazo,
Acting State Director.
