New Mexico Unit of the Central Arizona Project
Additional Information and Documents

The AWSA provides $66 million (indexed) for the Unit, or other water utilization alternatives in southwestern New Mexico, setting aside an additional $34 million (indexed) for construction of a Unit if a Record of Decision approving it is issued by the Secretary by 2019. This date may be extended to 2030 by the Secretary for reasons beyond the control of New Mexico.

The Agreement and the AWSA specifically call for full environmental review of a potential Unit, including review under the National Environmental Policy Act (NEPA), the Endangered Species Act, the National Historic Preservation Act and related statutes. As allowed by the AWSA, New Mexico, acting through the NMISC has requested to be a joint lead for NEPA purposes. Agreements are being developed between Reclamation and the NMISC as joint leads, the Entity as project beneficiary, and other agencies that may play a role in the environmental compliance process outlining roles and responsibilities, funding arrangements and other requirements. In addition to working with the Entity and NMISC, Reclamation has met with the U.S. Forest Service, U.S. Fish & Wildlife Service, and U.S. Bureau of Land Management as potentially affected agencies to ensure reliable communication and cooperation moving forward with the NEPA process.

As the environmental review process begins, a sequence of activities will be developed, including early development of a full-range of alternatives that will inform the Entity, Interior, Indian Tribes and their communities and the public as analysis proceeds. This environmental review process will also provide opportunities for public participation. Topics for analysis will be addressed during public scoping, but will include impacts to fish and wildlife, hydrology, land use, economics, cultural resources, recreation, and ecosystem services. The NM Unit alternatives will be analyzed under the Federal Principles, Requirements, and Guidelines for Water and Land Related Resources Implementation Studies.

If a Unit is identified as a preferred alternative through the NEPA process and supported by the Secretary's Record of Decision, Reclamation is authorized to design, construct, operate and maintain the Unit. Per the AWSA, any or all of these responsibilities will be transferred to the Entity if requested. The Entity formally requested transfer of design authority by letter to the Secretary dated April 4, 2016. Reclamation will continue to work with the Entity to provide oversight and ensure design adheres to Reclamation design standards.
