(a) Except as provided in subdivision (e) of this section, each disconnected service line must be tested in accordance with this section before being reinstated; however, if provisions are made to maintain continuous service, such as by installation of a bypass, any part of the original service line used to maintain continuous service need not be tested. The limits of the test shall be in accordance with section 255.511(g) of this Part.

(b) For each service line to be operated at a pressure of not more than 20 psig (138 kPa), the test pressure shall be 50 psig (345 kPa) or three times the maximum allowable operating pressure, whichever is greater.

(c) For each service line to be operated at more than 20 psig (138 kPa) but not more than 60 psig (414 kPa), the test pressure shall be 90 psig (621 kPa).

(d) For each service line to be operated at more than 60 psig (414 kPa), the test pressure shall be 1.5 times the maximum allowable operating pressure.

(e) All exposed connections on low-pressure service lines temporarily disconnected from the main because of main renewals or other planned work shall be soap-tested at operating pressure and the entire service line shall be checked for leakage with a combustible gas indicator both at the time of turn on and on the following day.

  "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.",
