  "scopeCaveat": "This connector is the complete current dedicated Michigan Administrative Code Gas Safety corpus published by ARS/MOAHR from R 460.20101 through R 460.20606. It does not claim all Michigan utility, siting, excavation-damage-prevention, well, environmental, federal, local, or Commission order law. Three headings expressly marked rescinded are retained only in the verified inventory. The MPSC pipeline-safety program does not regulate hazardous-liquid pipelines, and this corpus must not be used to imply that it does.",
  "applicabilityCaveat": "Applicability depends on the definitions and exclusions in R 460.20101 and R 460.20102, MPSC jurisdiction, gas and facility type, intrastate or interstate status, gathering-line classification, operator status, waivers, federal preemption, and rule-specific conditions. MPSC inspects jurisdictional intrastate gas systems and acts as an interstate agent for inspections and investigations; PHMSA retains interstate enforcement authority. MPSC expressly states that its pipeline-safety program lacks hazardous-liquid-pipeline jurisdiction.",
  "incorporationCaveat": "The rules adopt specified editions of 49 CFR parts 40, 191, 192, and 199 and named API, ASME, and NACE/ISO standards.

Historical Guide to the Michigan Gas Safety Standards files, including the 25th edition guide, are not current rule artifacts and are not used by this connector.",

Public availability does not resolve rights in agency seals, site presentation, incorporated federal compilations, API, ASME, NACE/ISO standards, forms, or other third-party material; downstream redistribution requires separate rights review.",
