PIPELINE SAFETY REGULATORY INTERPRETATION
_________________________________________________________________
SECTION: 192.167
SUBJECT: Compressor stations
FACTS: New piping is proposed for use in connection with an extraction plant and
two attended onshore compressor stations built in 1968 and 1969. The
proposed piping has valves that could be used to isolate the compressors;
and, in addition, a shutdown device is planned for each station gate.
QUESTION: Will the proposed piping and shutdown devices require the installation of
emergency shutdown systems?
INTERPRETATION: Under §§ 192.13 and 192.167, each attended onshore compressor station
readied for service after March 12, 1971, must have an emergency
shutdown system that complies with §192.167. Also, §192.167
applies to any preexisting compressor station that is replaced,
relocated, or otherwise changed after November 12, 1970.
Inasmuch as the proposed piping and shutdown devices do not
involve replacement or relocation of the existing compressor
stations or have any substantial effect on the existing design or
construction of those stations, §192.167 would not require
emergency shutdown systems to be installed.
