Dear Mr. Johansen:

This concerns a phone conversation of January 2, 1981, with Ralph Simmons of this Office regarding questions in your letter of December 17, 1980. Your questions concerned the
relationship of the equipment described in §192.197(c) with the requirements of §192.739, and the relationship of the relief devices described in §192.197(c) wit the requirements of §192.743. Enclosed is an interpretation of the applicability of the particular sections referred to in your letter.

If I can be of further help in this matter, please let me know.

Sincerely,

Melvin A. Judah

PIPELINE SAFETY REGULATORY INTERPRETATION

NOTE:A pipeline safety regulatory interpretation applies a particular rule to a particular set of facts and circumstances, and, as such, may be relied upon only by
those persons to whom the interpretation is specifically addressed.

SECTION: §§192.197(c) or (c)(1), 192.739, and 192.743

SUBJECT: Pressure regulating and relief installation in high pressure distribution systems.

FACTS: None

QUESTION #1: The pressure regulating and relief installations described in §192.197(c) subject to the requirements of §192.739?

ANSWER: The pressure regulating and relief installations described in §192.197 for high pressure distribution systems are those for a service line with meter
and service regulator and series regulator, service regulator or other protective devices.

The requirements of §197.739 are for regulating stations such as a city gate measuring and pressure regulating station or a distribution regulator station installed in a gas distribution main regulating a multiple feed distribution system.

Since the pressure regulating and relief devices described in §192.197 are neither a city gate measuring and pressure regulating station nor a distribution regulating station regulating a multiple feed distribution system, they are not subject to the inspection and testing requirements of §197.739.

QUESTION #2: Are the relief devices described in §192.197(c)(1) and (3) subject to the requirements of §192.743?

ANSWER: For the same reasons given in the answer to question #1, the relief devices described in §192.197(c)(1) and (3) would not be subject to the testing requirements of §192.743.
