Transportation (USDOT).

[[Page 22559]]


ACTION: Notice of Intent (NOI) to prepare an Environmental Impact 
Statement (EIS).

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

SUMMARY: The FHWA, on behalf of the Arizona Department of 
Transportation (ADOT) is issuing this Notice of Intent (NOI) to solicit 
comment and advise the public, agencies, Tribes, and stakeholders that 
an Environmental Impact Statement (EIS) will be prepared for the 
Sonoran Corridor (State Route 410), a new highway between Interstate 19 
(I-19) and Interstate 10 (I-10) in Pima County, Arizona. FHWA, in 
coordination with ADOT, completed Tier 1 Final EIS and Record of 
Decision in October 2021 and addressed the need for additional 
transportation capacity and connectivity in Pima County. This Tier 2 
EIS will build upon the Tier 1 EIS process.

DATES: Comments on the NOI or the NOI Supplementary Information 
Document must be received on or before July 18, 2025.

SUPPLEMENTARY INFORMATION: The environmental review, consultation, and 
other actions required by applicable Federal environmental laws for 
this project are being, or have been, carried out under ADOT's 
assumption of FHWA's National Environmental Policy Act responsibilities 
through a Memorandum of Understanding dated June 25, 2024, and executed 
by the FHWA and ADOT.
    The EIS will be prepared in accordance with the requirements of the 
National Environmental Policy Act of 1969, as amended (42 U.S.C. 4321, 
et seq.); recent Council on Environmental Quality guidance; and other 
applicable Federal, State, and local laws and regulations.
    The purpose of the Sonoran Corridor, as established during the Tier 
1, is to improve the transportation network by affording better access 
to growth areas and activity centers, reduce predicted congestion and 
improve levels of service, and provide a system linkage between I-19 
and I-10.
    The proposed project is to build the Sonoran Corridor, a new high-
capacity transportation corridor between I-19 and I-10. ADOT has 
developed three preliminary build alternatives labeled Alternative A, 
Alternative B, and Alternative C. Each preliminary build alternative is 
located within the 2,000-foot corridor established by the Tier 1 
Selected Corridor Alternative. Each of the 400-foot wide preliminary 
alternatives consists of a new roadway ranging from 20.38 to 20.53 
miles in length, extending east from I-19 south of the El Toro Road 
alignment to the Alvernon Way alignment, then traveling north along the 
Alvernon Way alignment to approximately the Old Vail Road alignment, 
then traveling east along the Old Vail Road alignment and ending at the 
I-10/Rita Road intersection. The No Build Alternative involves taking 
no action except routine maintenance and other presently planned and 
programmed projects.
    Additional information on the purpose and need and alternatives, as 
well as maps and figures illustrating the project location, and 
coordination and public involvement efforts are provided in the NOI 
Supplementary Project Information available for review on the project 
website noted in the ADDRESSES section.
    The Tier 2 EIS will evaluate the potential social, economic, and 
environmental impacts resulting from the implementation of the build 
alternatives and the No Build Alternative. The following resources are 
anticipated to be evaluated in detail during the environmental review 
process: Cultural and Historic Resources; Biological Resources and 
Wildlife Connectivity; Socioeconomics, Land Use, and Planned 
Development; Waters of the United States; Section 4(f); and Noise. 
Additionally, the EIS will also identify impacts to farmlands; 
recreation; topography, geology, and soils; hydrology, floodplains, and 
water resources; energy; Section 6(f) resources; air quality; 
transportation; hazardous waste sites; and visual resources.
    Anticipated permits and authorizations that could be required prior 
to the commencement of construction include:
     U.S. Army Corps of Engineers (USACE) approvals under 
Section 404 of the Clean Water Act and Section 401 water quality 
certification;
     Arizona State Land Department (ASLD);
     Bureau of Reclamation (Reclamation) authorization of the 
Central Arizona Project Canal crossing;
     State Historic Preservation Officer (SHPO) consultation 
under Section 106 of the National Historic Preservation Act;
     U.S. Fish and Wildlife Service (USFWS) approvals under the 
Endangered Species Act, the Bald and Golden Eagle Protection Act, and 
Migratory Bird Treaty Act; and
     Natural Resources Conservation Service approval under the 
Farmland Protection Policy Act.
    Public engagement activities for the Tier 2 EIS involved an initial 
public notification at the onset of the study and an online survey 
instrument in September 2024 to gather input on current and future 
transportation issues, alternative locations, interchange locations, 
and changes in conditions of the area. This survey also gathered 
feedback on the public support of the project's ability to serve the 
needs identified during the Tier 1 EIS. Agency coordination meetings 
include an Agency Early Scoping Meeting held in March 2024, Cooperating 
Agency meetings held between February 2025 and May 2025, a 
Participating Agency
