DEPARTMENT OF THE INTERIOR
Bureau of Reclamation
San Carlos Irrigation Project, Arizona
AGENCY: Bureau of Reclamation, Interior.
ACTION: Notice of intent to prepare an Environmental Impact Statement
(EIS) and notice of public scoping meeting.
-----------------------------------------------------------------------
SUMMARY: The Department of the Interior, Bureau of Reclamation,
announces its intent to prepare an EIS pursuant to the National
Environmental Policy Act of 1969, as amended, on the rehabilitation of
San Carlos Irrigation Project (SCIP) water delivery facilities near the
communities of Casa Grande, Coolidge, and Florence in Pinal County,
Arizona. SCIP canals convey irrigation water from the Gila River and
Central Arizona Project (CAP) to agricultural lands in the San Carlos
Irrigation and Drainage District (SCIDD) and Gila River Indian
Community.
The EIS will evaluate alternatives for rehabilitation of existing
facilities and construction of new facilities to meet the objectives of
the Gila River Indian Community Water Rights Settlement Agreement, as
amended, pursuant to Title II of the Arizona Water Settlements Act of
2004 (Pub. L. 108-451).
DATES: Written comments on the scope of the EIS will be accepted until
October 18, 2010.
A scoping meeting will be held to solicit public input on the scope
of the environmental document, alternatives, concerns, and issues to be
addressed in the EIS. The scoping meeting will be a 4-hour open house.
The meeting will be held on Saturday, September 18, 2010, 10 a.m.-2
p.m., Coolidge, Arizona.
ADDRESSES: The public scoping meeting will be held at the Coolidge
Police Department, City Council Chambers, 911 South Arizona Boulevard,
Coolidge, Arizona.
Send written comments on the scope of the EIS to Mr. John
McGlothlen, Bureau of Reclamation, 6150 West Thunderbird Road,
Glendale, Arizona 85306; or e-mail at [email protected].
Those not desiring to submit comments or suggestions at this time,
but who would like to receive a copy of the Scoping Notice and/or EIS,
should write to the address given above. Scoping information will also
be available on Reclamation's Phoenix Area Office Web site at http://www.usbr.gov/lc/phoenix.
FOR FURTHER INFORMATION CONTACT: Mr. John McGlothlen at 623-773-6256,
or e-mail at [email protected].

SUPPLEMENTARY INFORMATION:
Background
The purpose of the proposed action is to conserve water, reduce
maintenance requirements and associated costs, and improve service to
SCIDD and Gila River Indian Community lands. The SCIP system has more
than 95 miles of main canals that are unlined, and water losses from
infiltration and evapotranspiration are significant. The long length
and large cross section of the canal system relative to the service
area, combined with the system's age, make operating and maintaining
the facilities challenging. Rehabilitation and modernization of canals
will conserve water and reduce maintenance requirements by shortening
the length of the conveyance system needed to serve SCIDD and Gila
River Indian Community lands. In addition, provisions for increased
storage and modernized measurement and control will improve service to
customers while providing additional avenues for water conservation.
The proposed action includes the reconstruction and lining of major
canals, such as the Florence-Casa Grande, Casa Grande, and North Side
canals, and construction of new check structures and cross-drainage
features. The existing Florence Canal and Florence-Casa Grande Canal
Extension would be converted to drainage and recharge channels to
protect rehabilitated canals and associated project lands. These
conversions would reduce the size of the main water delivery system and
reduce maintenance requirements. A new canal would be constructed to
connect the rehabilitated Florence-Casa Grande Canal with the
rehabilitated Casa Grande Canal. The project would also include
relocating laterals or placing short reaches of laterals in pipeline to
accommodate changes in land use within the SCIDD service area.
Alternatives currently under consideration include:
Construction and repair of wells adjacent to the North
Side Canal to allow delivery of a combination of groundwater and Gila
River water to the SCIDD service area.
Construction and repair of wells adjacent to the North
Side Canal to allow delivery of only groundwater to the SCIDD service
area.
Implementation of an exchange agreement between SCIDD and
the Central Arizona Water Conservation District to allow delivery of
CAP water to rehabilitated North Side Canal facilities through proposed
interties with the CAP Aqueduct. The exchange agreement would also
allow flexibility during rehabilitation of the Florence-Casa Grande
Canal and facilitate long-term operational reliability of the SCIP
system.
Construction of mid-system and lower-system reservoirs to
store irrigation water. Sites presently under consideration may also
afford suitable conditions for hydropower generation.
A portion of the water that is conserved from lining SCIP canals
would be made available to the Secretary of the Interior for exchange
with water stored in the San Carlos Reservoir to maintain a permanent
minimum pool in the reservoir for fish and wildlife. Water that is
exchanged for this purpose would be retained in the San Carlos
Reservoir and not released to the Gila River.
Indian trust assets associated with the proposed action consist of
Gila River water conveyed through SCIP facilities to the Gila River
Indian Community and conserved water that is retained in the San Carlos
Reservoir to maintain a minimum pool.
Special Assistance for Public Scoping Meeting
If special assistance is required at the scoping meeting, please
contact Ms. Jessie Haragara at 623-773-6251, or e-mail at
[email protected]. Please notify Ms. Haragara at least 2 weeks in
advance of the meeting to enable Reclamation to secure the needed
services. If a request cannot be honored, the requestor will be
notified.
