Under Public Law 86-121 Project NA-03-P11, the Navajo Area Indian Health Service (IHS), Office of Environmental Health and Engineering (OEHE), spent $731,449 to provide community water service and individual waste disposal facilities to 28 homes within the White Rock Chapter. This document reports Project NA-03-P11 activities, including a project history, the facilities installed, construction experience, project costs, and details relating to training, rights-of-way, and transfer.
The project is located within the Navajo Nation, in San Juan County, approximately 45 miles south of Farmington, New Mexico, along New Mexico State Highway 371.
The White Rock Chapter submitted a Resolution requesting the IHS to study the feasibility of providing water and sewer service to Navajo homes located in the White RockChapter. IHS responded the by initiating a planning agreement allocating $50,000 for project planning activities. The IHS, OEHE, developed a Project Summary that recommended construction of approximately 63,300 feet of water waterline extension and septic tank/drainfields to provide water and sewage disposal facilities to 28 homes. The Project Summary was approved on July 21, 2003 and assigned project number NA-03-P11. A Memorandum of Agreement (MOA) 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, EPA was executed on September 30, 2003. This Agreement stipulated the provisions of the project including areas of responsibility, types of facilities, and method of construction (see MOA Appendix). Table 1 is a chronology of significant documents and events pertaining to NA-03-P11.
The NECA constructed the facilities of this project. The IHS contributed funds to NECA to cover all of their non-profit project costs. The IHS also provided engineering services and construction materials. The White Rock Chapter provided bathroom additions where required.
Tables 2, 3, 4, and 5 summarize the facilities installed under Project NA-03-P11.

ANALYSIS OF PROJECT COSTS
Project NA-03-P11 costs totaled $731,449. The average cost per home for this project was $26,123. The IHS and CDBG provided Regular Funds in the amount of $984,000. IHS and EPA expenditures both totaled $731,449. A balance of $252,551, will be returned to IHS bulk project funds. Table 6 details Project NA-03-P11 costs.
(Note: Accounting for projects with multiple funding sources shall be according to the PS/MOA. For example, EPA CWA projects shall include all sewer expenditures, support services, and a pro rata share of NECA overhead, Arch, T&E, SWPP, general credit card, and sewer related credit card charges.)

The White rock Base water system consisted of a water well , 90,000 gallon water storage tank, and served the Laundromat, watering point, and the Chapter house prior to completion of P11 project. The system was operated by White Rock chapter. The original scope of work for Project NA-03-P11 included service to 37 homes. The actual construction only served 28 homes, the homes not constructed were either due to a homeowner moving away or was deceased. The bathroom additions being constructed under the Chapter House was the only thing that delayed the waterline connections and plumbing (including rough-in and final fixture setting) to these homes. The waterline pipeline construction encountered some rocky areas but it did not delay the project. Once the project was completed the entire water system was transferred to NTUA.
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 that result from the proper use of these facilities. The responsibility to operate and maintain the community facilities constructed under this project rests with 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 IHS on-going training for water and sewer systems O&M.
The IHS has processed the necessary right-of-way requests. At this point BIA is still processing the request for the As-Built Right-of-Way. Copies of other right-of-way documents, including Grants-of-Easement and archeological clearances, are in the Right-of-Way Appendix of this report.
TRANSFER OF OWNERSHIP
The community facilities for the off-site water and sewer were transferred to the Navajo Nation as mentioned. The individual facilities were transferred to the individual homeowners at the same time.
