INTRODUCTION

Under Public Law 86-121 Project NA-97-L77, the Navajo Area Indian Health Service (IHS), Office of Environmental Health and Engineering (OEHE) spent $822,069 to provide community water service and individual waste disposal facilities to 62 homes at Tachee – Blue Gap, Arizona. This document reports project history, the facilities installed, construction experience, project costs, and details relating to training, rights-of-way, and transfer.

PROJECT LOCATION

Tachee-Blue Gap community is located in northeastern Arizona within the Navajo Nation. The project area is located 30 miles west of Chinle, Arizona on Bureau of Indian Affairs (BIA) Highway Rt. 4.




PROJECT HISTORY


On October 28, 1994 the Tachee-Blue Gap Chapter of the Navajo Nation submitted a project proposal to the IHS requesting assistance in providing sanitation facilities under P.L. 86-121 to

serve 73 existing homes. The IHS, OEHE, developed a Project Summary which recommended that the Burnt Corn Valley Water System be extended and that community water service and individual waste disposal facilities be installed to serve 62 homes.


The Project Summary was approved in February 1997 and assigned project number NA-97-L77. A Memorandum of Agreement (MOA) between the Navajo Nation; the IHS; the Navajo Engineering and Construction Authority (NECA), an enterprise of the Navajo Nation; the Navajo Tribal Utility Authority (NTUA), an enterprise of the Navajo Nation; and the Environmental Protection Agency (EPA) was executed on August 6, 1997. This Agreement stipulated the provisions of the project, including areas of responsibility, types of facilities, and method of construction (see MOA Appendix). On June 29, 1998 a letter serving as Amendment No. 1 to the Memorandum of Agreement was executed to decrease the not-to-exceed level from $1,162,000 to $1,037,000 for the completion of sanitation facilities construction. Construction of Project NA-97-L77 started in June 1998 and was completed by December 1998. Table 1 is a chronology of significant documents and events pertaining to Project NA-97-L77.

SUMMARY OF FACILITIES INSTALLED

The NECA constructed the facilities for this project, excluding the interior plumbing. The IHS made a contribution to the NECA to cover their nonprofit project costs. The IHS also provided engineering services and construction materials. The IHS provided the materials and labor for the installation of the interior plumbing. Bathroom additions were constructed by the Tachee-Blue Gap Chapter for homes requiring additions. Facilities installed under project NA-97-L77 include 54,690 feet of 6-inch, 17,008 feet of 4-inch, and 18,720 feet of 2-inch water main with all necessary appurtenances such as gate valves, flush valves, air release valves, and wash and road crossing material. Individual one-inch water service connections were made to all 62 homes. All homes required individual pressure reducing valves. On-site wastewater disposal facilities for all homes consisted of a 1,000-gallon septic tank and drainfield. Tables 2, 3, and 4 summarize the facilities installed under Project NA-97-L77.

L = Lavatory B = Bathtub WH = Water Closet



CONSTRUCTION EXPERIENCE

Construction was completed without complications.


OPERATION, MAINTENANCE, AND TRAINING

The IHS, OEHE, offered training to the homeowner, 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 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 operation and maintenance.


RIGHT-OF-WAY

The IHS obtained right-of-way and archaeological clearance for all facilities constructed under this project. Copies of right-of-way documents including grants-of-easement and affidavits-of-completion are included in the Right-of-Way Appendix in this report.


TRANSFER OF OWNERSHIP

The community facilities were transferred to the Navajo Nation on May 30, 2000. The individual facilities were transferred to the individual homeowners at the same time.
