Mr. John G. Wilson
Vice President
Natural Gas Distributing Co
Box 690
Ogallala, Nebraska 69153
Dear Mr. Wilson:
This is in reply to your letter of December 20, 1970, concerning your responsibility for service
lines downstream of the customer meter and on the customer's property.
Section 192.3, 49 CFR, of the Minimum Federal Safety Standards defines a service line as a
distribution line that transports gas to a customer meter set assembly from a common source of
supply. It is our contention that under this regulation the burden is on the operator to ascertain
the safe condition of the customer service lines to which has is delivered.
Our regulations do not apply to the question of who performs the installation of lines or who
bears the cost installation.
We hope this answers your question, and if you have any further, do not hesitate to ask.
Sincerely,
/signed/
Joseph C. Caldwell
Director, Acting
Office of Pipeline Safety
192.3 SERVICLI 1
