1. Service Lines. Each gas system shall conduct a study at intervals not exceeding twenty-four months to determine the number of inactive service lines in their system and shall take necessary steps to meet the following: a. Inactive service lines for which there is no definite plan for future use or reasonable possibility for future use or are found to be in unsafe condition shall be physically disconnected from the gas supply at the main, purged and the open pipe ends shall be sealed. b. Inactive service lines for which there is a definite plan for future use or a reasonable possibility for future use may remain connected to the gas supply at the main if such lines are found to be in safe condition, provided that in addition to maintaining such lines in accordance with all other applicable requirements, such lines be monitored at intervals not exceeding twenty-four months by leakage survey to detect conditions detrimental to public safety.

  "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."
