(a) Each operator shall inspect each service regulator when it is installed, at the time of periodic meter change, and at the time a service which has been inactive for a period of two years or more is reactivated to service.

(b) An operator may elect to inspect service regulators at intervals not to exceed 20 years in lieu of inspection at the time of periodic meter change.

(c) Service regulators serving multiple meter installations need not be inspected at the time of each individual meter change, however, each associated regulator shall be inspected at least once each 20 years.

(d) The inspection of the service regulator shall include the following tests:

(1) An outlet pressure test shall be taken under minimum load conditions. Minimum load condition, for purposes of this paragraph, shall mean no load or pilot load only. The pressure limits of this test shall be as established by this Part.

(2) The operational pressure test shall be taken on the outlet side of the regulator with one or more appliances in operation. The acceptable limits of pressure shall be as established by this Part.

(e) Each operator shall inspect each service regulator associated vent whenever the service regulator is inspected. This inspection shall include a test for the presence of gas, proper location of vent terminus, proper size, and proper installation of a weather-insect resistant fitting and verification by an inside the building inspection that the vent line piping is continuous and is properly connected to the regulator. Immediate remedial action shall be taken if any of these items do not pass inspection.

  "legalScope": "Complete current terminal legal unit exposed by the DPS-designated Title 16 NYCRR pipeline-safety part inventory.",
  "applicabilityCaveat": "Applicability depends on the part and section, Commission jurisdiction, commodity and facility type, intrastate or interstate status, operator and activity, exemptions, waivers, federal preemption, Commission orders, and incorporated law. DPS inspects portions of interstate systems for PHMSA, but PHMSA retains federal enforcement authority. DPS states that all jurisdictional Part 256 gas-holder and Part 257 LPG-plant facilities have been decommissioned even though those regulations remain unrepealed.",
  "incorporationCaveat": "These parts incorporate or rely on federal pipeline regulations, federal and New York statutes, Commission rules and orders, and privately authored technical standards. Part 10 supplies incorporation details. References metadata preserves explicit citations but does not reproduce external material, determine licensing rights, or decide whether a particular incorporation is static or dynamic.",
  "publicationCaveat": "The New York Department of Public Service identifies these eleven Title 16 NYCRR parts as its state pipeline-safety regulations and links to the public DOS/Westlaw NYCRR reading copy. That site labels the online text unofficial and directs users needing evidentiary accuracy to the Official NYCRR maintained by the Department of State Division of Administrative Rules. Each section's 'Current through' date is the most recent official NYCRR supplement covering that section, not a uniform corpus-wide amendment date.",
  "rights": "New York government-edict text is preserved with DPS, Department of State, and publisher attribution. The public reading site's presentation and enhancements, agency marks, forms, annotations, and incorporated federal or privately authored standards require separate rights review; this connector does not claim rights in those materials.",
