SUPPLEMENTARY INFORMATION: Boulevard Associates, LLC (Boulevard), a 
fully owned subsidiary of NextEra, LLC, is proposing to construct an up 
to 375-megawatt (MW) concentrated-solar-thermal (CST) power plant and 
ancillary facilities on 3,620 acres (5.78 square miles) of mostly BLM-
administered land. The proposed CST project would be sited in the 
Little Rainbow Valley, east of State Route 85, and south of the Buckeye 
Hills in Maricopa County, Arizona. This is in BLM's Lower Gila South 
Planning Area which is managed in accordance with the Lower Gila South 
Resource Management Plan (RMP) (1988), as amended (2005). Boulevard has 
applied for a 14,759-acre right-of-way (ROW); the footprint of the 
proposed SSEP would total approximately 3,620 acres (5.78 square miles) 
of mostly BLM land. The project would also include land owned by the 
Arizona State Land Department (5.23 acres) and private parties (6.04 
acres). Related facilities would include road construction and 
improvements, a gas pipeline, electric lines, and a water well field 
and pipeline. Boulevard's ROW application only applies to BLM-
administered land.
    The BLM's purpose and need for Federal action is to respond to 
Boulevard's application under Title V of FLPMA (43 U.S.C. 1761) for a 
ROW grant to construct, operate, and decommission a solar power plant 
on public lands in compliance with FLPMA, BLM's ROW regulations, and 
other applicable Federal laws. The BLM will decide whether to approve, 
approve with modification, or deny issuance of a ROW grant to Boulevard 
for the proposed SSEP. If approved, the solar facility would operate 
for approximately 30 years based on the purchase power agreement(s) 
with utilities.
    The BLM completed a land use plan conformance analysis of the 
project proposal and determined that the proposed land use is in 
conformance with the Lower Gila South RMP, as amended. As part of its 
review of the Boulevard ROW application, the BLM considered the Energy 
Policy Act of 2005 and Secretarial Orders 3283 Enhancing Renewable 
Energy Development on the Public Lands and 3285A1 Renewable Energy 
Development by the Department of the Interior.
    The Proposed Action would consist of two independent, concentrated 
solar electric generating facilities with expected outputs of 125 MW 
and 250 MW. Both facilities would use parabolic trough solar thermal 
technology to produce electrical power using steam turbine generators. 
The generators would connect to a new SSEP 500-kilovolt (kV) onsite 
switchyard. Electricity from the new switchyard would be transmitted 
through a generation tie-line connecting to the existing Jojoba 
Switchyard. The Proposed Action would use a wet-cooling tower for power 
plant cooling with up to 3,003 acre-feet per year of water being 
supplied from an onsite groundwater well field. Three natural gas co-
firing boilers would be constructed to augment solar heating when less 
than optimal solar conditions existed (night time, cloud cover, etc.), 
and would provide up to 25 percent of the annual total electric 
production. The boilers would be supplied with natural gas via a new 5-
mile-long, 8-inch pipeline. A thermal energy storage (TES) system may 
also be installed to supplement electrical output during reduced solar 
activity or to extend electrical output into the evening hours. The TES 
would use molten salt as its energy storage material. The proposed SSEP 
would include a number of related facilities and infrastructure 
including power blocks and solar trough arrays (2,300 acres), 
evaporation ponds, access roads, administration buildings and other 
support facilities, a land treatment unit, drainage collection and 
discharge facilities, as well as open areas (totaling 1,300 acres).

    As required under NEPA, the EIS also analyzes a No Action 
alternative which would preclude development of the SSEP in any 
configuration and maintain existing land uses in the project area. The 
four action alternatives are: (1) The Proposed Action (as described 
above); (2) Alternative A: Reduced Water Use (using a dry-cooling 
technology); (3) Sub-alternative A1: Photovoltaic (PV) (a 300-MW PV 
facility occupying 2,013 acres); and (4) Alternative B: Reduced 
Footprint (a 250-MW wet-cooled facility occupying 2,320 acres). 
Alternatives A and B were developed in response to issues raised during 
the scoping process. Sub-alternative A1 was developed in response to 
agency and public comments on the Draft EIS as an alternative to 
Alternative A for reducing water consumption. Sub-alternative Al would 
use PV technology instead of solar thermal technology to reduce water 
use, to decrease the project footprint, and to avoid other issues 
related to sensitive resources raised by the public and agency 
cooperators. The use of PV technology was originally eliminated from 
further analysis in the Draft EIS due to technological and economic 
infeasibility. However, changing technology and market conditions have 
made PV technology feasible, and thus, full consideration of PV 
technology has been added to the Final EIS. A Brine Concentrator Option 
is also analyzed as a component of the Proposed Action and Alternative 
B.
    The BLM has identified Sub-alternative A1 (which would use PV 
technology) as the agency-preferred alternative, which would reduce 
water consumption as well as mitigate other resource issues. This sub-
alternative would reasonably accomplish the purpose and need for the 
Federal action while fulfilling the BLM's statutory mission and 
responsibilities, giving consideration to economic, environmental, and 
technical factors. In particular, this sub-alternative best addresses 
public and agency concerns regarding groundwater use while meeting the 
purpose and need. Under Sub-alternative A1, approximately 33 acre-feet 
of groundwater reserves in the Rainbow Valley aquifer would be removed 
and used annually during operations. This is approximately 98 percent 
less than the estimated water requirements of the Proposed Action (the 
highest water use alternative, which would use wet-cooled CST 
technology) and 72 percent less than the estimated water requirements 
of Alternative A (the lowest water use alternative after Sub-
alternative A1, which would use dry-cooled CST technology). No modeled 
detectable drawdown to previously existing wells would occur under Sub-
alternative A1. In addition, the total estimated acreage of surface 
disturbance under Sub-alternative A1 (2,013 acres)--the least surface 
disturbance of all action alternatives--is approximately 44 percent 
less than under the Proposed Action and approximately 15 percent less 
than under the reduced footprint of Alternative B. The smaller overall 
project footprint would also reduce adverse impacts to other resources 
and uses (e.g., wildlife, visual resources, soils, vegetation) compared 
to other action alternatives. Sub-alternative A1 would generate 
approximately 775,000 MW hour per year of electricity, which is 
approximately 89 percent of the generation under the wet-cooled 
Proposed Action, 101 percent of the generation under Alternative A, and 
144 percent of the generation under Alternative B.
    Four agencies are serving as cooperating agencies in the 
preparation of the Final EIS because of their jurisdictional 
responsibilities and/or special expertise. Cooperating agencies are the 
Arizona Game and Fish Department, the Arizona Department of Water 
Resources, the City of Goodyear, and the Town of Buckeye.
    A Notice of Intent to Prepare an EIS for the Proposed Sonoran Solar 
Energy Project, Maricopa County, Arizona was published in the Federal 
Register on July 8, 2009 (74 FR 32641). The BLM held three public 
scoping meetings in Phoenix, Buckeye, and Gila Bend, Arizona, on August 
4, 5, and 6, 2009, respectively. The formal 30-day public scoping 
period ended September 8, 2009. On April 19, 2010, the BLM published in 
the Federal Register a Notice of Availability for the Draft EIS for the 
Proposed Sonoran Solar Energy Project, Maricopa County, Arizona, which 
initiated a 45-day public comment period (75 FR 20377). The BLM again 
held three public meetings in Phoenix, Gila Bend, and Buckeye, Arizona, 
on April 27, 28, and 29, 2010, respectively. The formal 45-day public 
comment period ended May 24, 2010. Comments on the Draft EIS received 
from the public and internal review were considered and incorporated as 
appropriate into the Final EIS. There were 161 comment letters 
received; the responses are included in the Final EIS. The majority of 
the comments received expressed concern about the amount of water to be 
used, as well as potential effects on air quality conformance, cultural 
resources, visual resources, and wildlife.
    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 
request your personal identifying information be withheld from public 
review, we cannot guarantee that we will be able to do so.

    Authority: 40 CFR 1506.6, 1506.10, and 43 CFR 1610.2.
