Dear Mr. Searcy:
Thank you for your letter of July 26, 1974, asking whether 49 CFR 192.197 (a) provides for protection against overpressure due to failure of a regulator.
Sections 192.197(a) and (b) protect against unsafe operation of gas utilization equipment due to overpressuring by a distribution system. Paragraph (a) sets forth criteria for a service regulator to provide this protection. Under paragraph (b), where a regulator does not meet that criteria, the operator must install suitable devices to protect against overpressure when the regulator fails. The problem of providing protection against overpressure due to failure of a regulator which meets the criteria of paragraph (a) is not addressed by the regulation.
We trust our response is helpful to you.
Sincerely,
SIGNED
EDWARD F. CYGAN
Joseph C. Caldwell
Director
Office of Pipeline Safety
