Dear Mr. Hendrickson:
Thank you for your letter of August 3, 1971, requesting an interpretation of §192.167 of 49 Code of Federal Regulations, Compressor station: emergency shut down.
In effect you ask two questions. The first is if a station is attended only during start up and shut down and is totally unattended while in operation does it qualify as being unattended. The answer is yes. If personnel are not assigned to the station during the period of operation the station is unattended.
The second question you pose is whether the regulation applies to all compressor stations. Again the answer is yes. The only compressor stations that are excepted are those that are unattended field compressors of 1,000 horsepower or less. The use of the word field as a modifier is a carry over from §843.431 of the B31.8 1968 code. It denotes a compressor station that is used to pump gas directly from a gathering system of a production field.
We hope that this interpretation will clarify the problems that you are having in understanding §192.167.
Joseph C. Caldwell
