Johansen\nProject Manager/Case Coordinator\nUtility Division\nMissouri Public Service Commission\nP. O. Box 360\nJefferson City, Missouri 65102\nDear Mr. Johansen:\nWe have considered the permanent waiver of 49 CFR 192.619(a)(3) which the Commission\ngranted the Kansas Power and Light Company for the MAOP of a portion of its lower pressure\ndistribution system in Kansas City, Missouri.\nIn view of the overpressure protection devices installed on the system to limit the MAOP to 5\npsig for operation under §192.619(a)(6), and the history of operation at that setting, we do not\nbelieve any significant safety benefits would result if the operator were compelled to modify the\nregulating station's overpressure protection devices to protect the company facilities to the current\nmaximum actual operating pressure of 2.2 psig. Therefore, we have no objection to continue to\nhave the overpressure devices set to limit the pressure to 5 psig with the condition that the system\ncontinue to operate at, or below, its current pressure of 2.2 psig.\nSincerely,\nRichard L. Beam\nDirector\nOffice of Pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\619\\88-08-04\n1","truncated":false,"body_characters":1160}
