Electra Street Number

[Maren Ruminski]

Theprovisions of this section shall apply to and be co-extensive with the territory within the boundaries now designated, or which may hereafter be established as the fire limits of the City of Electra, except such provisions as are by special reference made applicable to all the territory within the corporate limits of said City, and said fire limits as now established are hereby declared to be as follows:

It is hereby adopted by the City of Electra, Texas, for the purpose of establishing rules and regulations for the erection, construction, enlargement, alteration, repair, moving, removal, conversion, demolition, occupancy, equipment, use, height, areas, and maintenance of buildings and structures, that certain building code known as the International Building Code (Latest Edition), in the whole thereof, except as hereinafter amended, including all appendices thereto. One copy of said code shall be on file in the office of the City Administrator and the same is hereby adopted and incorporated as fully as if set out at length herein, and the same shall be controlling in the construction of all buildings and other structures within the city limits of the City of Electra, Texas.

In the event of a conflict between the provisions of the building code adopted by reference in subsection A above, and any provision of the City Code of Ordinances, the provisions of the Code of Ordinance shall prevail.

(1) Federal Minimum Safety Standards - Each natural gas service line (extending from the gas main to the meter and including any portion owned by the customer) must be installed, tested and maintained in accordance with regulations issued by the Office of Pipeline Safety Operations.

(5) Multiple Meter Installations - Where more than one meter is desired for a given building, the gas company may set as many meters as there are separate consumers applying for service, connecting the meters to one service pipe, provided that the piping extended to such different consumers from their respective meter connection outlets are plainly and permanently marked to identify the part of the building served by each meter.

(6) Delivery Pressure - Gas will be delivered to the consumer at 4 ounces per square inch gauge pressure at the meter outlet. When the consumer has unusual gas consumption requirements and when approval is requested in advance of the installation of piping, the gas company may, at its option, deliver gas at 5 pounds per square inch gauge pressure or at unregulated distribution system pressure. The consumer shall then provide additional pressure regulation as required. Approval by the gas company of a request for gas delivery at a pressure greater than 4 ounces will generally be considered only if the system meets one of the following conditions:

(c) Volume of gas required and piping distance are such that it is economically unfeasible for the system to be operated at a pressure of 4 ounces (connected loads in excess of approximately 1,000,000 BTU and length of pipe from meter to the most remote outlet in excess of 300 feet may generally be considered as meeting these conditions); or

(8) Inauguration of Service - No person, firm, or corporation other than the gas company or its employees or agents shall initially inaugurate gas service to a consumer. Where the gas company has discontinued gas service to a consumer for any reason, no person, firm or corporation other than the gas company or its employees or agents shall reinaugurate gas service to the consumer.

(1) Quality - All pipe used for the installation, extension, alteration, or repair of any gas piping shall previously have been used for no purpose other than for conveyance of gas. All such pipe shall be free from internal obstructions, foreign matter, or imperfections which would render it unsatisfactory for the purpose intended.

(3) Metallic Pipe, Piping Joints, and Fittings[*] - Metallic gas pipe shall be black steel or wrought iron complying with ANSI Standard for Wrought Steel and Wrought Iron Pipe, B36.10. Lengths of underground metallic pipe shall be joined by welding. Metallic fittings (except stopcocks or valves) shall be steel, malleable or ductile iron. Metallic fittings may be screwed, flanged, or welded to metallic pipe.

(4) Metal Tubing, Tubing Joints, and Fittings - Seamless copper or steel tubing may be used for gas piping. When copper tubing is used for gas piping, only the tin lined type is permitted. Steel tubing shall comply with the Specification for Electric-Resistance-Welded Coiled Steel Tubing for Gas and Fuel Oil Lines, ASTM A539 or ANSI Standard Specification for Copper Brazed Steel Tubing, B36.35 (ASTM 254). Metallic tubing joints shall be made with approved gas tubing fittings. Metallic ball sleeve compression type tubing fitting shall not be used.

(5) Service Line Valves - Service line valves shall be of a type suitable for the intended service, shall provide positive cut-off at all pressures up to 60 psig, and shall be designed and constructed to minimize the possibility of the removal of the valve core with other than specialized tools. The following valves, or their equivalent, are acceptable: Dresser 175-GTO, Mueller H11116, or McDonald 521B.

(2) The minimum size and maximum lengths of pipe for house piping may be determined from Table 1. In no case shall any section of piping be smaller in size than any pipe which it supplies. Yard lines shall be included with house piping in determining the minimum size and maximum lengths of pipe permissible for the system.

(3) Branch lines (piping extending to any single riser pipe) and riser pipes (vertical piping to the gas outlet) shall not be less than inch in size and in no case smaller than the connection on the appliance to be served.

(4) Customer-0wned service line piping shall not be less than 1-1/4 inch nominal diameter for new installations. (Piping with a smaller nominal diameter may be used when service piping is being renewed by plastic pipe or tubing insertions.)

(6) The following tables can be used in sizing pipe for installations with 4 ounces and 5 pounds delivery pressure. Procedure for using figures in Table 1 are given; however, the same method may be used in sizing pipe for both delivery pressures.

(b) For each section of pipe determine the total gas demand supplied by that section. Where gas piping sections serve both heating and cooling equipment and the installation prevents both units from operating simultaneously, only the larger of the two demand loads need be used in sizing these pipe sections.

(c) In Table 1, select the column showing the length measured, or the next longer length if the table does not give the exact length . Use this column to locate ALL gas demand figures for this particular system of gas piping.

(d) Starting at the most remote outlet, find in the vertical column just selected the gas demand for that outlet. If the exact figure of demand is not shown, choose the next larger figure below in the column.

(g) When the project involves longer pipe runs or greater gas demands than those covered by Table 1, the size of each piping system shall be determined by standard engineering methods and each such system shall be so designed that the total pressure drop between the meter or other point of supply and any outlet, when full demand is being supplied to all outlets, will at no time exceed five-tenths (0.5) inches water column pressure.

Problem: Determine the required pipe size for each section and outlet of the piping system shown in Figure 1 above. Gas to be used has a specific gravity of 0.60 and a heating value of 1000 BTU per cubic foot, delivered at 4 ounces gauge pressure.

(7) Prior to the installation of a gas piping system to serve multiple buildings or mobile homes, a piping plan showing the proposed location and sizes of pipe shall be submitted to the gas company for approval.

(8) Additions to existing house piping and changes because of increases in demand shall conform to the provisions of these rules. Additions shall not be made to existing pipe which is smaller than that permitted by these provisions; such existing piping shall be replaced by the proper size pipe.

(1) Gas piping in buildings shall be supported with pipe hooks, metal pipe straps, or hangers suitable for the size piping, of adequate strength, and located at proper intervals so that the piping cannot sag or be moved accidentally from the installed position. Gas piping shall not be supported by other piping.

(6) Metallic pipe shall not be bent; approved fittings shall be used for making changes in direction. Metallic tubing and plastic pipe and tubing may be bent provided that the bend causes no buckling, wrinkling or other evidence of mechanical damage.

(13) Metallic piping in contact with the earth or other material which may corrode the piping, shall have an insulating coating, be insulated from other underground structures, and be placed under cathodic protection using galvanic anodes.

(14) Customer-owned service line piping shall be installed with a minimum cover of 12 inches. Depth shall be increased to 18 inches for connection to the company-owned service lines at street or alley property lines. The ends shall be plugged or capped to prevent the entry of foreign substances or water.

(15) Where the gas meter is to be located at the end of the customer-owned service line (normally near the building) a service riser must be installed for the inlet to the meter. A manual shut-off line valve (see Service Line Valves) must be installed in the riser not less than 4 inches above the ground and the valve must be plugged or capped.

Where the gas meter is to be located at the property line a riser must be installed on the end of house piping for the outlet of the meter. Meter loop fittings must be installed in the riser and the end plugged or capped.

(17) Plastic pipe shall be installed underground on undisturbed or well compacted soil. Bed the plastic piping in sand or other suitable granular material where necessary to prevent damage to it by rocky backfill material. An electrically conductive wire shall be installed adjacent to the pipe to facilitate locating it with an electronic pipe locator.
