## Document text

(a) The pressure must be increased gradually, at a rate that can be controlled.

(b) Prior to the first pressure increase and at the end of each incremental increase, the pressure must be held constant while the entire segment of the pipeline that is affected is leakage surveyed.

(c) Each hazardous leak detected must be repaired before a further pressure increase is made. All leaks must be repaired as soon as possible following completion of the upgrading.

(d) Each operator who upgrades a segment of pipeline shall retain for the life of the segment a record of each investigation required by this Part, of all work performed, and of each pressure test conducted, in connection with the upgrading.

(e) Each operator who upgrades a segment of pipeline shall establish a written procedure that will ensure compliance with each applicable requirement of this Part.

(f) Except as provided in section 255.555(c) of this Part, the new maximum allowable operating pressure may not exceed the maximum that would be allowed under sections 255.619 and 255.621 of this Part for a new segment of pipeline constructed of the same materials in the same location. However, when uprating a steel pipeline, if any variable necessary to determine the design pressure under the design formula (section 255.105 of this Part) is unknown, the MAOP may be increased as provided in section 255.619(a)(1) of this Part.

  ],
  "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.",
