Dear Mr. Johansen:
We have considered the permanent waiver of 49 CFR 192.619(a)(3) which the Commission
granted the Kansas Power and Light Company for the MAOP of a portion of its lower pressure
distribution system in Kansas City, Missouri.
In view of the overpressure protection devices installed on the system to limit the MAOP to 5
psig for operation under §192.619(a)(6), and the history of operation at that setting, we do not
believe any significant safety benefits would result if the operator were compelled to modify the
regulating station's overpressure protection devices to protect the company facilities to the current
maximum actual operating pressure of 2.2 psig. Therefore, we have no objection to continue to
have the overpressure devices set to limit the pressure to 5 psig with the condition that the system
continue to operate at, or below, its current pressure of 2.2 psig.
Sincerely,
Richard L. Beam
Director
Office of Pipeline Safety
