A. Each gas system shall maintain on its distribution system in each city in which it supplies gas a sufficient number of recording devices, but not less than one, to ensure detections of abnormal system pressures. No gas system shall maintain less than two such recording pressure gauges of which one should be portable. Electronic and/or remote type devices may be utilized in addition to maintaining a portable pressure recording gauge. B. Each gas system shall keep records of each test of pressures in various parts of its distribution systems. The records obtained shall include as a minimum, the date, time, and location where the pressure was taken and shall be retained for a two year period. These records may be electronic with suitable back-up means, and the ability to generate a hard copy upon request of the ORS.

  "caveats": {
    "exactScope": "This bounded corpus contains 27 current, direct South Carolina gas-pipeline safety provisions: 14 provisions from Chapter 103, Article 4, including only pipeline-safety portions 103-412(2.6)-(2.7), and 13 provisions from the South Carolina Gas Safety Act of 1970, S.C. Code Sections 58-5-920 through 58-5-1070. The complete current Chapter 103 gas-systems article and complete current Gas Safety Act article are inventoried as the completeness boundary.",
    "excludedScope": "Customer deposits, billing, rates, certificates, economic service, routine metering, gas quality, curtailment, ordinary utility records, and related engineering provisions are adjacent or excluded and are not searchable. Chapter 58-36 excavation and one-call law, tariffs, dockets, orders, inspection forms, enforcement files, federal text, private standards, and non-gas programs require separate corpora. Interstate gas and all hazardous-liquid pipelines are excluded from the proven state-certification scope.",
    "applicability": "Applicability depends on the statutory definition of gas utility and pipeline facility, public-utility and gas-system status, commodity, facility type, intrastate or interstate status, federal jurisdiction, statutory exclusions for liquefied petroleum gas and anhydrous ammonia, waivers, and the text in force on the relevant date. PHMSA identifies South Carolina as certified for intrastate gas only and retains interstate gas and both intrastate and interstate hazardous-liquid enforcement. This connector does not infer hazardous-liquid certification.",
    "incorporation": "Regulation 103-490 and Sections 58-5-920, 58-5-970, and 58-5-1050 use rolling language for federal gas-safety standards as amended from time to time. Regulation 103-461 also points to editions of private standards referenced by federal rules. This connector links but does not reproduce incorporated federal or private standards and does not decide edition, preemption, or incorporation-validity questions.",
    "publication": "The South Carolina Legislature's current Code of Regulations index, official Chapter 103 PDF, and current Code of Laws HTML are the controlling publication set used here. Rule histories and statutory history notes support only the explicit events emitted; retrieval time is a publication observation, not a legal event or historical version.",
    "rights": "Official South Carolina and federal-government artifacts are retained with attribution and SHA-256 provenance. Public access does not establish unrestricted rights in site presentation, agency marks, forms, photographs, linked material, or incorporated private standards; private standards are not reproduced."
