§ 233.1

Effective date; changes.

The regulations in this part are approved for the conduct of the electric power system of the San Carlos Project, Arizona, referred to in this part as the Project. The regulations in Part 231 of this subchapter shall no longer be applicable to the said Project. The regulations in this part shall become effective with the first billings made after the first day of the second calendar month which begins after the date of publication in the FEDERAL REGISTER. The regulations in this part are subject to change by the proper authority and such changes shall apply to all contracts then and thereafter in effect.

Any aggrieved party may file with the Project Engineer a written complaint regarding the application of the regulations. Within fifteen days after its receipt, the Project Engineer shall render a written decision thereon and serve a copy thereof on the aggrieved party. Within fifteen days from receipt of such decision, the aggrieved party may take an appeal to the Commissioner of Indian Affairs who shall render his decision within sixty days and his decision shall be final. Pending the determination of an appeal, electric service shall be continued, except in cases in which the question of the existence of dangerous conditions on the premises of the consumer is involved, provided the consumer pays the amount of each bill for electric service prior to the time when it becomes delinquent. If the question of the amount of a bill is involved in an appeal, the consumer shall be deemed to have paid the bill under protest and the payment shall be held in a special deposit account until the final decision has been made.

§ 233.4 Applications; contracts.

In

In order to contract for the delivery of power, a written application for service under this part accompanied by the required cash deposit and guarantee of the required minimum revenues to the Project, shall be filed with the Project Engineer. Upon acceptance by him, the application will become a contract. general, such application will be accepted where service lines exist. When special terms and conditions are involved in contracting for service, the Project Engineer shall require the execution of a form of contract in which such terms and conditions are fully set forth. Each contract involving the construction of a new extension shall be for a period of at least one year, but if the consumer vacates the premises, he shall be liable for the unpaid guaranteed revenue only to the extent that it is not liquidated by the succeeding occupant of the premises.

A cash deposit in an amount equal to twice the estimated monthly bill, but in no case less than $10.00 will be required from each applicant except that when the premises to be serviced are owned by the applicant, no deposit need be required until a delinquency in the payment of a bill has occurred. Any cash deposit, less the amount of any unpaid bills, shall be refunded after the termination of service. Before extensions are constructed each applicant must deposit an amount sufficient to cover his portion of the required minimum charges for a period of not less than one year, and must otherwise establish his credit and satisfy the Project Engineer of his intention to take service and his ability to meet the guarantee.

(b) The length of an extension shall include the horizontal length of both the primary and secondary circuits exclusive of the service drops. Insofar as practicable, all extensions shall be constructed along established highways. The prospective consumer, or consumers, shall furnish or procure satisfactory rights-of-way necessary for the lines and other facilities of the Project incidental to the furnishing of service. The Project Engineer may decline to construct any extension which, in his opinion, will be excessive in cost, or detrimental to the best interest of the Project, or for which funds are not available. All extensions when constructed shall be and remain the property of the United States.

§ 233.7 Installation or extension fi. nanced by consumer.

If funds, material or labor are not otherwise available for an installation

or extension, or if an extension to a prospective consumer will require new construction beyond the distances specified in § 233.6 of this part, the consumer or prospective consumer may, after executing an appropriate contract satisfactory to the Project Engineer, construct the needed installation or extension, or deposit funds estimated to be sufficient to pay for the construction. Such installations or extensions shall be built in accordance with suitable plans and specifications approved by the Project Engineer. The contract may provide that part or all of the cost of the installation or extension, but not more than the amount specified on the said contract, shall be refunded to the consumer by allowing him a monthly credit not to exceed 20 per cent of the bill for each month during the life of the contract or until the specified amount be refunded in full, but no claim for credit shall extend beyond the life of the contract. Unless the approval of the Commissioner of Indian Affairs or his duly authorized representative has been obtained, no refund shall be made for that portion of an extension not located along a public highway. All installations and extensions constructed under the provisions of this section shall be and remain the property of the United States.

§ 233.8 Temporary service.

Temporary service refers to service to circuses, bazaars, fairs, construction works, and other activities or businesses of such a nature that service to the premises occupied by them will probably be discontinued within five months. An applicant for temporary service shall be required to deposit with the Project Engineer of sum of money equal to the estimated cost of installing and removing the necessary facilities and also an additional sum equal to the estimated bill for electric service: Provided, however, That such additional sum need not be greater than three times the estimated monthly bill. After termination of service, there shall be refunded any amount remaining on deposit in excess of the actual cost of installing and removing facilities, plus the unpaid amount of bills for electric power and energy, as determined by the Project Engineer.

§ 233.9 Type of service.

Service for lights and the usual domestic and other appliances, including motors of less than five horsepower shall be single phase, ncminally 115 or 230 volts and two or three wire, except when special written approval for another type of service has been obtained from the Project Engineer. Three-phase service at suitable voltage may be furnished for motor installations of five-horsepower and over, provided a three-phase circuit of the required voltage and capacity is available where the service is desired. All service will be sixty cycle.

§ 233.10 Service connections.

On each new service the consumer shall provide and maintain a service entrance at a location convenient to the lines of the Project, and all connections from the service entrance to the meter base and from the meter base to the main line circuit breaker or distribution center. The meter socket and meter will be furnished by the United States. The meter socket shall be installed, however, by the consumer and in a suitable location, preferably on the outside of the building, or on the service pole, where the meter will be accessible to the meter reader at all times. The meter socket shall not be more than seven feet nor less than five feet above the ground or floor. The entire service installation must be satisfactory to the Project Engineer and must conform to the provisions, then in force, of the National Electrical Code of the National Board of Fire Underwriters for Electric Wiring and Apparatus. When alterations of a consumer's premises make it necessary to move an existing meter loop, the consumer may be required to install a meter socket in the new loop, located in conformity with the stipulations of this section. When an inspection is required by municipal ordinance, the Project Engineer shall require a certificate of inspection and approval by the municipal inspector before connecting a new service. § 233.11 Connection methods.

Service to a consumer's premises will ordinarily be supplied by means of overhead conductors. A consumer may at his own expense provide for an underground service. Such an underground service must be installed in accordance with the provisions of the National Electrical

Code and shall be terminated on the pole at a location and in the manner directed by the Project Engineer. No connection from the circuits of the Electrical Power System to a consumer's service entrance shall be made except by the Project or its agents.

§ 233.12 Multiple meter installations.

In the case of new installations in multiple-occupancy buildings such as apartment houses in connection with which more than one meter in a building is required, the meters shall be assembled at one central location. Each meter shall be clearly marked so as to make it possible to identify the consumer.

§ 233.13

Consumer responsibility.

The consumer shall furnish, install and maintain at his own risk and expense in good and safe condition all protective devices, electric wires, lines, machinery, apparatus, and appliances which may be required or used for receiving and consuming electric energy obtained from the Project.
