{
  "jurisdiction": "US-OK",
  "chapter": "OAC 165:20",
  "subject": "enforcement",
  "exactScope": "This corpus contains every current section in the Oklahoma Corporation Commission's dedicated OAC 165:20 Gas and Hazardous Liquid Pipeline Safety compilation: 47 current sections. It inventories 19 revoked and two reserved sections without making them searchable.",
  "excludedScope": "It does not claim all Oklahoma pipeline law. Statutes outside the direct authority check, federal text, Commission orders and dockets, pending rules, forms, tariffs, utility service and rates, oil-and-gas conservation, environmental permits, siting, rights-of-way, local law, and incorporated material are excluded. OAC 165:20-5-41, 7-3, and Subchapter 17 damage-prevention obligations remain included because they are current sections of the bounded chapter, but are classified in metadata as adjacent to operational pipeline safety.",
  "applicabilityCaveat": "Oklahoma and PHMSA identify the Commission's certified role as inspection and enforcement for intrastate gas and hazardous-liquid pipelines; PHMSA retains interstate enforcement. OAC 165:20 separately limits gas, hazardous-liquid, underground natural gas storage, drug-testing, enforcement, construction, and damage-prevention provisions. Inclusion does not establish that a provision applies to a particular operator, commodity, gathering line, storage facility, or interstate facility.",
  "incorporationCaveat": "OAC 165:20-5-21, 6-1, 7-1, and 11-1 adopt federal Parts 191, 192, 195, and 199 with all amendments and appendices, a dynamic formulation whose legal operation must be verified. Effective August 1, 2026, sections 5-41 and 7-3 also omit the former January 1, 2020 date from their adoption of the Oklahoma damage-prevention statute. The connector records the current wording but does not infer the timing or legal effect of future source amendments.",
  "publicationCaveat": "The OCC compilation is expressly unofficial; only the Oklahoma Secretary of State supplies official OAC copies. The OCC current-rules page identifies Chapter 20 effective August 1, 2026 as its current convenience copy, and that compilation identifies Oklahoma Register Volume 43, Number 21 and RM2025-000005 changes. Users must verify official SOS text and any later effective action.",
  "rights": "Official Oklahoma and federal government materials are archived with attribution and byte-level hashes. Public availability does not resolve rights in seals, site presentation, forms, linked documents, incorporated federal compilations, or third-party standards; downstream redistribution requires separate review.",
