  "scopeCaveat": "This is a bounded current Chapter 40 pipeline-safety corpus, not all Missouri pipeline law and not every gas-utility rule in 20 CSR 4240-40. It includes the complete selected Rules .020, .030, .033, and .080. Price-volatility, accounting, rate-schedule, depreciation-study, and renewable-natural-gas program rules are inventoried but excluded; three rescinded affiliate rules remain inventory-only.",
  "applicabilityCaveat": "Applicability depends on Missouri Public Service Commission jurisdiction, operator and facility status, the particular rule, federal preemption, exemptions, waivers, and Commission orders. The PSC states that its pipeline-safety jurisdiction covers operators of intrastate natural-gas pipelines, including covered municipal and investor-owned systems. Interstate gas pipelines are generally under PHMSA jurisdiction, and the PSC states that it does not have safety jurisdiction over hazardous-liquid pipelines or liquefied-petroleum-gas systems.",
  "incorporationCaveat": "The selected rules parallel, adopt, or incorporate federal requirements including 49 CFR Parts 40, 191, 192, 193, and 199, sometimes as editions fixed by the rule and with Missouri substitutions or additions. They also reference federal forms, manuals, technical standards, and other external material. This connector preserves explicit references but does not reproduce incorporated material or independently determine its licensing, current content, or legal effect.",
  "publicationCaveat": "The Missouri Secretary of State describes the CSR as updated monthly and warns that a rule printed in the current compilation may not yet be effective; the authority section supplies the effective date. This connector uses the October 31, 2025 official Chapter 40 compilation retrieved from the current URL and records only dates expressly stated in each selected rule's authority/history text.",
  "rights": "Official Missouri rule text and government source pages are retained with attribution and cryptographic provenance. Public availability does not determine rights in state seals, site presentation, incorporated federal or privately authored standards, forms, manuals, or linked third-party material; downstream redistribution requires a separate rights review.",
