INTRODUCTION
Under Public Law 86-121, Project NA-96-M12, the Navajo Area Indian Health Service (IHS), Office of Environmental Health and Engineering (OEHE), spent $202,568 to provide community water service and sewage disposal facilities to 15 homes within the Gallup Service of the IHS. This document reports project history, the facilities installed, construction experience, project costs, and details relating to training, rights-of-way, and transfer.
PROJECT LOCATION
The project area is located within the Navajo Nation, in the Tsayatoh and Rock Springs Chapters, McKinley County, New Mexico, approximately eight miles northwest of Gallup, New Mexico.
PROJECT HISTORY
In May 1994, the Rock Springs and Tsayatoh Chapters of the Navajo Nation submitted resolutions to the IHS requesting the existing water system be extended to serve numerous homes located in Rock Springs Chapter and in the northern portion of Tsayatoh Chapter.
On June 14, 1995 the IHS responded to the resolutions by initiating a Planning Agreement allocating $88,000 for preliminary engineering, right of way, archaeological studies and other activities associated with the project. On April 1, 1996 a project proposal was submitted by the Rock Springs and Tsayatoh Chapters. The IHS, OEHE, developed a four-part Project Summary, which recommended in part, extending the existing water line to serve 15 homes. The Project Summary was approved on May 21, 1996 and assigned project numbers NA-96-L30, M11, M12, and M13. A single Memorandum of Agreement (MOA) for Project NA-96-M12, between the Navajo Nation; the IHS; the Navajo Engineering and Construction Authority (NECA), an enterprise of the Navajo Nation; and the Navajo Tribal Utility Authority (NTUA), also an enterprise of the Navajo Nation was executed on July 23, 1996. Construction of Project NA-96-M12 started in May 2000 and was completed by November 2000. Table 1 is a chronology of significant documents and events pertaining to Project NA-96-M12.

Project NA-96-M12 costs totaled $202,568. The average cost per home for this project was $13,505. This amount is approximately one-half of the estimated cost. IHS provided complete funding. A balance of $187,431.60 will be returned to IHS bulk project funds.

TOTAL PROJECT EXPENDITURE $202,568
CONSTRUCTION EXPERIENCE
Construction costs were significantly less than expected when rock excavation was not encountered. Also, during the project, it was necessary to bore under the Burlington Northern-Santa Fe Railroad tracks and cross an El Paso Natural Gas high-pressure gas line two times. In both instances these operations were less complex than planned.
OPERATION, MAINTENANCE, AND TRAINING
The IHS, OEHE, offered training to the homeowners, emphasizing the proper use and maintenance of on-premise facilities and giving attention to the health benefits which result from the proper use of these facilities. The responsibility to operate and maintain the community facilities constructed under this project rests with the NTUA. The NTUA personnel involved in operation and maintenance (O&M) of these facilities received initial training from the IHS and have the opportunity to participate in the IHS on-going training for water and sewer systems O&M.
RIGHT-OF-WAY
The IHS obtained right-of-way and archaeological clearance for all facilities constructed under this project. Copies of other rights-of-way documents including grants-of-easements and affidavits-of-completion are included in the Right-of-Way Appendix in this report.
The community facilities were transferred to the Navajo Nation on February 11, 2005. The individual facilities were transferred to the individual homeowners at the same time.
