Dear Mr. Hanawalt:

In response to your letter of July 10, 1974, requesting an interpretation of Part 192 and Part 195 of Title 49 of the Code of Federal Regulations concerning the requirements for valve operator mechanisms, we wish to point out:

  1. In Part 192 Subpart B – Materials – Section 192.53 General materials for pipe and components and Subpart D – Design of Pipeline Components – Section 192.143 General requirements, would apply to pipeline components.  In addition, there are requirements that valves and operating devices must be readily accessible and protected from tampering and damage in section 192.179 Transmission line valves.
  2. Part 195 contains the following material requirements that would be applicable to valve operators if the conditions described fit the operating methods of the device: Section 195.116 Valves (b) materials subject to the internal pressure of the pipeline system, including welded and flanged ends, must be compatible with the pipe or fittings to which the valve is attached. (c) Each part of the valve that will be in contact with the commodity stream must be made of materials that are compatible with each commodity that it is anticipated will flow through the pipeline system.

The Office of Pipeline Safety (OPS) does not approve or endorse any proprietary item, but holds the pipeline operator responsible for compliance with the regulations.

We hope that this provides a better understanding of the applicability of the DOT requirements.  Thank you for your interest in pipeline safety.

Sincerely,

SIGNED
Joseph C. Caldwell
Director
Office of Pipeline Safety
