TRENCHING The meter set assembly shall not be placed under any operable window or air duct, within 10 feet of any adjacent air duct, or within 10 feet of any source of ignition. 5.1 TRENCH The customer's service piping must be installed in a trench that is separate from other utilities, drains etc., except as noted in Section 5.4. The trench bottom shall be continuous, relatively smooth, and free of rock. The width of the trench shall be sufficient to provide for adequate room for visual inspection and compacting side fills. 5.2 DEPTH The trench shall be of sufficient depth to provide 3' minimum cover at the street and 2'-6" minimum cover at the service riser. The remainder of the service route shall have 2'-6" nominal cover. Service piping installed in sod areas shall have at least 2'- 0" cover. Company's construction drawing may specify different depth requirements depending on your application. 5.3 TRENCH CLEARANCES The service piping must not be installed closer than three feet to septic systems, drains, conduits, other utility ducts, lines or pipes. If the service piping must cross over, under or near one of the above, a twelve inch minimum separation must be maintained. Exception: Gas service piping in joint service trench must not be closer than six inches to shared trench utilities. See Section JOINT SERVICE TRENCH Service piping may be installed in a joint service trench with electric service cable in conduit, telephone cable, and television cable. The pipe must not be closer than six inches from these cables. If the gas piping must cross any of these cables, the six inch minimum separation must be maintained. Only electric, telephone, and cable television utilities are permitted in the same trench with gas piping. There are no exceptions. When other facilities parallel gas piping, three feet of separation between trenches must be maintained. If the gas piping must cross a facility other than shared trench occupants, a twelve inch minimum separation must be maintained. All occupants in the trench with gas service piping must enter the building above ground level. The requirements are for gas piping and electric service cable only. Contact your PAGE PL-3

4 cable television company and your telephone company for their requirements. 6. INSTALLING THE SERVICE 6.1 PLASTIC TO PLASTIC JOINTS Plastic to plastic joints shall be accomplished by butt fusion. Only individuals qualified by the Company are permitted to make fusion joints on plastic pipe. Company inspector shall record names and social security numbers of individuals making fusion joints. 6.2 PLASTIC TO STEEL JOINTS Plastic pipe to steel pipe transition shall be accomplished using a transition fitting or coupling with stiffener listed in Exhibit B. Coupling with stiffener to be tightened by Company at time of visual inspection. 6.3 TRACER WIRE A #12 AWG or heavier (smaller AWG number), solid, insulated (RHW, THW, or polyethylene insulation is recommended), copper wire shall be taped to pipe at 15 to 20 foot intervals. Do not wrap wire around pipe. The wire must be one continuous, unbroken length. Coil tracer wire at meter location and street end with enough wire to extend a minimum of two feet above grade. 6.4 TRACER WIRE BOXES Plastic gas services longer than 1000 feet in length from curb valve to meter riser must have tracer wire boxes installed at customer's expense in accordance with Company standards. Contact your Cinergy representative for requirements. 6.5 DAMAGED PIPE Pipe found to be buckled, fractured, kinked, cut gouged beyond 10 percent wall thickness, or contaminated by exhaust, oil, or dirt must not be used. 6.6 CHANGE IN DIRECTION Changes in direction will be made with fusion elbows where minimum bending radius of plastic pipe must be exceeded. The minimum bending radius for each service size is as follows: Service Size With Fusion Joints No Fusion Joints 3" 4" 6" 8" 25' 30' 45' 60' PAGE PL-4 5' 7' 10' 15' Mitered joints, and cut or altered plastic fittings are prohibited. Transition fittings and couplings are not permitted within 10 feet of a bend.

5 6.7 SERVICE RISER Company construction drawing will specify riser and concrete meter pad dimensions for your particular application. See "Corrosion Protection" for coating and cathodic protection of steel risers. 7. CORROSION PROTECTION 7.1 GENERAL Protection of underground metallic piping against corrosion shall be accomplished by coatings, designed specifically for use on underground pipe, and cathodic protection, by the use of magnesium anodes. 7.2 MILL APPLIED COATINGS Steel service pipe designed for under ground use having an acceptable coating applied at a coating mill is available and is preferred. Acceptable mill applied coatings include reinforced coal tar enamel, extruded polyethylene, and fusion bonded epoxy. 7.3 FIELD APPLIED COATINGS Bare steel pipe, fittings, and welds located below ground must be field coated with an acceptable coating system designed for underground use. Paint type coating are not acceptable. Field applied coatings must be installed in accordance with the manufacturer's instructions. In general, these materials should be spiral wrapped and overlapped 1/2 inch minimum. Acceptable field applied coatings include coal tar/synthetic resin tape with plastic backing, coal tar/synthetic resin tape with glass reinforcement, pressure sensitive polyethylene or polyvinyl chloride tape, or wax impregnated tape. See Exhibit C for acceptable manufacturers of field applied coatings. Surfaces to be coated must be dry, and free of loose rust, scale, and foreign material prior to coating application. 7.4 ANODES Anodes used for protection of short sections (less than 30 feet) of buried steel gas piping such as service risers for plastic gas services consist of 3 pounds of magnesium with connecting wire attached, centered in a bag containing lowresistance backfill material. Larger sizes are available and may be used. PAGE PL-5

6 Anodes are buried a minimum distance of two feet from the pipe and at or below the pipe depth and back filled with soil. The connecting wire shall be attached to the steel pipe using a thermite weld or brazed connection. The point of attachment to the service must be cleaned to a bright metal to insure a durable, low resistance connection. After the connection is made, exposed steel shall be coated with acceptable coating material. 8. VISUAL INSPECTION The customer's service trench shall not be backfilled until the pipe has been visually inspected and approved by a Company representative. If the electric service lateral also occupies a joint service trench, the appropriate electrical code inspection authority must inspect it before the trench can be backfilled. After you have completed the installation, and before you backfill, call for visual inspection. Except where tunneling is necessary, the gas service pipe must be completely visible and exposed from end to end. All fusion joints must be visible. If the service piping is being installed using trenchless technology, Company personnel must inspect the actual pipe installation. 9. BACKFILLING The service should be continuously supported beneath its entire length by clean, firm backfill material (no rocks). Intermittent blocking shall not be used to support plastic pipe. The first layer of fill must be free of rocks, stones, cinders, slag, concrete blocks, pieces of wood, or other materials that may cause damage to the pipe or pipe coating. If native rock free spoil is not available, the first layer of fill material around and 6" over the pipe shall be sand. Pea gravel, crushed stone, and lime stone backfill are not permitted. 10. PRESSURE TEST AND TIE-IN The pressure test and tie-in are done after the service line has passed the visual inspection and has been backfilled. Delays can occur on the test and tie-in if the service line has not been backfilled. Obtaining permits to excavate from various communities can also cause delays. An inspection fee is charged for the service piping pressure test. There is no charge for the gas meter installation or service tie-in. PAGE PL-6
