## Document text

LPG facilities shall meet the following requirements:

Siting requirements shall be governed by NFPA 59 (as described in section 10.3 of this Title).

Automatic plants (i.e., remotely controlled or unmanned while operating) shall be equipped with flame detectors (which will cause the plant to fail-safe) and combustible gas detectors and such other equipment to transmit alarms to the appropriate gas corporation office, and in the event of fire to the local fire department. Heat sensors may be substituted for flame detectors within structures or in any other area where it can be demonstrated that the heat sensor is more effective than a flame detector.

Wall openings shall be at or near floor level.

Two separate and distinct entrances must be provided at each plant site to allow for emergency and/or fire fighting equipment to gain emergency access.

All devices associated with calorimeters or calorimixers which may vent gas within the room in which the unit is located shall be vented through piping to the outside atmosphere.

If compressor stations are involved in the facility they shall meet all of the requirements of section 255.163 of this Title.

  "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.",
