You\nasked if electronic data collection by airborne remote sensing technique is an acceptable means of\ninspection under that rule.\nThe rule does not prescribe a means of inspection. Therefore, an operator has the freedom to\nconduct its inspections utilizing whatever appropriate technology or means it chooses.\nThe acceptability of electronic data collection by airborne remote sensing technique would depend\non the capability of this means to meet the purpose of §§192.463(a) and 192.465(b) and (c). It\nwould also depend on the reliability of the data transmitted to operators. These are matters that\nFederal and State field inspectors would determine when conducting an inspection and reviewing\nthis relevant data.\nSincerely,\nCesar De Leon\nDirector of Pipeline Safety\nRegulatory Programs\nDB\nC:\\WP51\\INTERPRT\\192\\463\\91-11-07\n1","truncated":false,"body_characters":1151}
