## Document text

Every gas corporation engaged in the storage, terminaling, handling, transfer, vaporization or air-gas mixing of liquefied petroleum gas (LPG) within the State of New York shall comply with the rules set forth in this Part. Except where otherwise indicated, it is not intended that these rules be applied retroactively to existing installations or to those under construction as of the effective date of this order insofar as design, fabrication, installation or testing are concerned.

This Part does not apply to:

(1) design and fabrication of pressure vessels covered by the ASME Boiler and Pressure Vessel Code, section VIII, Pressure Vessels, Division 1(as described in section 10.3 of this Title);

(2) proprietary items of equipment, apparatus or instruments;

(3) heat exchangers; or

(4) prefabricated units which employ plate and longitudinal welds, as contrasted to pipe.

If a waiver of or deviation from the application of any rules prescribed in this Part is indicated because of special facts, application may be made to the Public Service Commission for waiver of or deviation from the rules and regulations in this Part. Each request shall include a full and comprehensive justification for such requested waiver or deviation, together with a proposed alternate rule to be considered for application to the condition(s) requiring the waiver or deviation.

  "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.",
