## Document text

(a) Any device used to perform a leakage survey on a Petroleum Gas Distribution System shall be designed and calibrated for detecting Petroleum Gas. (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

  "scopeCaveat": "This corpus contains all 117 dedicated pipeline-safety sections newly codified as RCSA 16-280b-A1 through A75, B1 through B32, and C1 through C10 by Connecticut Secretary of the State File Number 6446. The filing also amends four adjacent legacy utility provisions and repeals eleven obsolete 16-11 provisions; those actions are retained as provenance and inventory rather than mixed into the dedicated searchable corpus.",
  "applicabilityCaveat": "Applicability varies by natural-gas or petroleum-gas operator, public-service-company status, pipeline facility, master-meter or petroleum-gas distribution system, activity, waiver, and federal jurisdiction. PURA states that Connecticut has no intrastate transmission or gathering lines and that hazardous-liquid pipelines remain under PHMSA jurisdiction.",
  "incorporationCaveat": "The rules supplement and repeatedly incorporate federal pipeline requirements, generally as amended from time to time, and rely on Connecticut statutes and external standards. References are recorded without reproducing incorporated material or deciding federal preemption or facility-specific legal effect.",
  "publicationCaveat": "The authenticated final filing was posted to the Connecticut eRegulations System and became effective June 11, 2025. It is used instead of the older browse pages, some of which still display pre-2025 text and stale update labels.",
