(a) Each Operator shall ensure each Service Regulator is replaced as soon as practicable after water has entered the regulator. (b) Not later than January 1, 2031, plastic pipe used to vent Service Regulators: (1) shall not be located inside a building; and (2) may be located outdoors, provided it meets one of the following specifications: (A) uses polyvinyl chloride conduit that meets the requirements of UL-651, Standard for Schedule 40, 80, Type EB and A Rigid PVC Conduit and Fittings; or (B) uses flexible conduit that meets the requirements of UL-1660, Standard for Liquid-Tight Flexible Nonmetallic Conduit, with fittings that meet the requirements of UL-514B, Standard for Conduit, Tubing, and Cable Fittings. (c) Each Operator shall ensure that the pipe and fittings used to vent regulators shall not inhibit the ability of the regulator relief to limit downstream pressure to the pressure requirements pursuant to section 16-280b-B13(d) of the Regulations of Connecticut State Agencies. (d) Service Regulators shall be labeled to reflect the interchangeable components, such as orifice size and spring pressure range at the time such Service Regulators or components are installed, changed or replaced. (e) Service Regulators shall be inspected periodically by the Operator to ensure they are in working order. The inspection shall consist of external examination of the regulator, its piping, seal, vent line and operating condition and shall include verifying the lock- up pressure. Any Service Regulator found functioning improperly shall be replaced or repaired immediately.

  "effectiveDateEvidence": "Secretary of the State confirmation states that the regulation became effective June 11, 2025.",
  "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.",
  "rights": "Official Connecticut legal and agency materials are retained with attribution and cryptographic provenance. State marks, site presentation, forms, annotations, and incorporated federal or privately authored material require separate review.",
