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 under certain circumstances.

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 have been 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, U.S. Bureau of Land Management, and US Army Corps of Engineers as potentially affected agencies to ensure reliable communication and cooperation moving forward with the NEPA process.

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.
