Dear Mr. Roedder:

This responds to your letter of April 9, 1975, requesting certain information relevant to pipeline
safety.

Pipeline safety studies by this Office which are the subject of outside contracts are being made
available upon completion of the contract through the National Technical Information Service
(NTIS), Springfield, Virginia 22151. Other studies underway are for internal use and are not
prepared for publication. The following studies are being made available through NTIS:

  1. Study of the technology of current practices for transporting, transferring, and storing
    LNG.
  2. State-of-the-art study on liquefied petroleum gas pipeline facilities.
  3. Study of the liquid and gas pipeline industry practices concerning shutdown of failed
    facilities and pressure limiting devices.
  4. Study of odorants and their effectiveness in alerting people to the presence of natural gas.
  5. Tools and procedures study for assessing the safety of existing gas distribution systems.
  6. Study of practices in using plastic materials in gas pipelinefacilities.
  7. Study of current practices, technologies, problems, and recommendations relating to the overall safety of gas pipeline distribution systems.

We have added your name to our list of persons to receive copies of new pipeline safety
regulations this Office proposes by notice in the Federal Register.

You asked for copies of planned rules concerning plastic gas lines and line marking. We have
enclosed recent amendments to the Federal gas pipeline safety standards dealing with these
subjects:

Amendment 192-19: Qualification for Use of Plastic Pipe

Amendment 192-20: Line Markers for Mains and Transmission Lines

Also enclosed is a copy of Notice 75-1 concerning emergency procedures for gas utilities.

The safety problem of installing a gas and electric line in the same trench is addressed by Section
192.467 of the Federal standards, a copy of which is enclosed. We are not currently considering
further regulation in this area.

We appreciate your interest in pipeline safety.

Sincerely,

Joseph C. Caldwell
Director
Office of Pipeline Safety
