Since the only difference in the two distribution systems you\nportray is the size of the operator, the two systems are subject to the same inspection and test\nrequirements.\nYou request that we identify specific inspections and tests the operator would be required by\n§192.739 to conduct. Specifically, you asked if set-point, lock-up, and full-stroke operation are\npart of the required inspections and tests.\nSet-point, lock-up, and full-stroke are undefined in Part 192 and are not specified as necessary for\ncompliance with § 192.739. Section 192.739 requires all pressure limiting and regulating stations\nto be subjected, at intervals not exceeding 15 months, but at least one each calendar year, to\ninspections and tests to determine if the station has the qualities listed in paragraphs (a)-(d) of §\n192.739.\nRegulator stations must be inspected and tested to comply with\n§ 192.739 using any practicable method that will demonstrate the presence or absence of the\nlisted qualities. Set-point, lock-up, and full-stroke-operation would be part of the inspection and\ntesting if such tests are practicable at the station concerned. If not, whatever other tests are\npracticable in meeting the requirements of § 192.739 must be used. Specific procedures should\nbe documented in the utility's operating and maintenance plan prescribed by § 192.605.\nIf you have further questions, please contact Mr. Jim Thomas, Regional Director, Southwest\nRegion (713-750 1746).\nSincerely,\nCesar De Leon\nDirector, Regulatory Programs\nOffice of Pipeline Safety\nJT\n192.605/92-10-22","truncated":false,"body_characters":1855}
