## Document text

At least 30 days prior to the start of construction or reconstruction of any LPG facility, or portion thereof, each gas corporation shall file with the department a letter of intent, together with general design data for the proposed facility. The department shall be promptly notified of any significant change affecting the initial filing which may occur after submission of the initial filing. This requirement is intended to provide notice in those cases where piping alterations, installation of additional LP storage tanks, etc., could affect the safety of the facility. The requirement is not intended to apply to normal maintenance requiring replacement of small sections of existing pipe, etc.

At least five days prior to the commencement of any tests required by this Part during construction or reconstruction, the operator shall make notification to the department, except in an emergency shorter notice may be given.

Before any LPG facility is placed into operation, a report shall be filed with the department certifying that the facility has been constructed and tested in accordance with the requirements of the rules prescribed in this Part. The report shall include a summary of tests made pursuant thereto. Detailed results of all tests shall be available for examination by representatives of the department.

  "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.",
