Utah Admin. Code R746-320-5 - Design, Construction, and Operation of Plant

A. Generally --

1. Facilities owned or operated by utilities and used in furnishing gas shall be designed, constructed, maintained and operated so as to provide adequate and continuous service. Utilities shall, at all times, use every reasonable effort to protect the public from danger and shall exercise due care to reduce the hazards to which employees, customers, and others may be subjected from their equipment and facilities.

2. Utilities shall use accepted good practice of the gas industry, but in no event shall those practices be construed to require less than required by this rule, R746-409, Pipeline Safety in Utah, Chapter 13 of Title 54, and the federal Natural Gas Pipeline Safety Act, 49 U.S.C. Section 1671 et seq.

B. Regulators -- If the gas pressure maintained in a customer's service line exceeds the standard delivery pressure, the utility concerned shall install an approved service regulator on the service line on the customer's premises. The regulator shall be set to deliver gas within the established delivery pressure range and shall have a vent piped to the outdoors if the regulator is located within a building. If pressure in the service line exceeds 100 p.s.i.g., a primary regulator, in addition, shall be installed on the service line outside the building. Regulators shall not be required for service of industrial or commercial customers served through high pressure meters.

C. Main Extensions -- Utilities shall adopt, with Commission approval, uniform rules and regulations governing main extensions.

D. Installation and Maintenance of Service Lines and Meters --

1. Utilities shall furnish, install and maintain, free of charge, a gas service line from the gas main adjacent to customers' premises to the customers' property lines or curbs, except that utilities shall not be required to install the piping on the outlet side of meters.

2. Customers may be required by utilities to install or pay in full or in part for gas service lines from property lines to customers' buildings in accordance with approved tariffs.

3. Service lines and meters shall be owned and maintained by utilities.

E. Service Lines for Temporary Service --

1. Utilities may provide temporary service to customers and may require the customers to bear any costs, in excess of any salvage value realized, of installing and removing service lines.

2. Temporary service shall be considered service provided for emergency or short-term use, as specified in approved tariffs, or service for speculative operations or those of questionable permanency.

F. Gas Service Line Valves --

1. New gas service lines, entering customers' buildings, which are operating at a pressure greater than 10 p.s.i.g., and other service lines two inches or larger, I.P.S., shall be equipped with a gas service line valve located on the service line outside buildings served. If a service line valve is underground, it shall be located in a durable curb box at an easily-accessible location. The top of the curb box shall be at ground level and shall be kept visible by the customer.

2. Service lines shall be equipped with a gas service line valve near the meter. If a service line is not equipped with an outside shut-off, the inside shut-off shall be a type which can be sealed in the off position.
