(b) If a Barhole leakage survey is performed, the: (1) leakage survey shall include tests of the atmosphere in all manholes, at cracks in pavement and sidewalks, and immediately adjacent to structure foundations; and (2) Barholes shall be: (A) placed adjacent to the Pipeline; (B) at the approximate depth of the Pipeline; (C) spaced approximately 20 feet apart; and (D) placed immediately adjacent to structure foundations. (c) A Pressure Drop Test may be utilized as the leakage survey required pursuant to 49 CFR 192.723, as amended from time to time, under the following conditions: (1) the pressure in the Pipeline shall be at least equal to the operating pressure; (2) the duration of the test shall be commensurate with the volume of the Pipeline; and (3) the test pressure shall be in the middle third of the range on the gauge used to monitor the test. (d) A Pipeline shall not be returned to service if there is an indication of a leak during a Pressure Drop Test. (e) If any leakage survey indicates the presence of Petroleum Gas at a structure foundation, the interior of the structure shall be immediately checked by the Operator for the presence of Petroleum Gas. (f) Immediately after Petroleum Gas is introduced into a Main or Service Line that has been restored after an interruption of service, a leakage survey shall be conducted by the Operator on the Main or Service Line. 45","truncated":false,"body_characters":1545}
