Gas Pipeline Safety Division — Pipeline Safety Interpretation

Page 1PI-74-0134 08-19-74 Mr. T. K. Spalding, Director Gas Pipeline Safety Division West Virginia Public Service Commission Charleston, WV 25305 Dear Mr. Spalding: This responds to your letter of August 1, 1974, requesting an interpretation of the meaning of the term "service line" with respect to two drawings shown in the letter. As defined in 49 CFR Part 192.3 a "service line" extends a connection to customer's piping or a customer meter whichever is farther downstream. In each drawing, the meter is farther downstream than the connection to customer's piping; and the pipeline from main to downstream side of the meter is a "service line." The customer's piping is covered by the Federal gas pipeline safety standards to the extent it lies upstream of the meter. We trust this explanation is helpful to you. Sincerely, /signed/ Joseph C. Caldwell Director Office of Pipeline Safety 192.3 SERVICLI 1#

The meter in the top situation is at the foundation well, while in the lower situation the meter is located at the property line. INSERTED HERE DIAGRAM OF SKETCH Your very truly, T. K. Spalding, Director Gas Pipeline Safety Division 192.3 SERVICLI 2#
