This rule requires\noperators to provide for periodic leakage surveys of distribution systems \"at intervals not\nexceeding 5 years.\" You said that because of the absence of a definitive \"due date\" for\nconducting leakage surveys, state agencies and industry representative have expressed multiple\ninterpretations of this requirement.\nUnder § 192.723(b)(2), each leakage survey may not be more than 5 years from the last one.\nThus, in the 5th year after the date of the last leakage survey, the operator must conduct another\nleakage survey on or before the day that corresponds to that date.\nI trust this adequately responds to your request.\nSincerely,\nCesar De Leon\nDirector, Regulatory Programs\nOffice of Pipeline safety\nJT\n192.723/92-10-01 1","truncated":false,"body_characters":1092}
