  "category": "pipeline-construction-and-siting",
  "currentThrough": "2026-08-01",
  "currentnessBasis": "Official publisher states the entire administrative code is current and updated on the first day of each month.",
  "legalScope": "This completeness-verified corpus contains every current section of Wisconsin Administrative Code Chapters PSC 133, 134, and 135, plus complete Wis. Stat. §§ 196.745 and 182.0175. Chapter PSC 135 is the dedicated gas-safety chapter. Chapters PSC 133 and 134 are included because the Wisconsin PSC identifies all three chapters as requirements used in pipeline-safety inspections; they also contain broader construction, siting, utility-service, billing, metering, and customer provisions.",
  "applicabilityCaveat": "Applicability depends on Wisconsin PSC jurisdiction, operator and facility type, intrastate or interstate status, gas-public-utility status, project thresholds, activity, exemptions, waivers, Commission orders, federal preemption, and the specific provision. Wis. Stat. § 196.745 excludes propane distribution systems from the PSC pipeline-safety program, while the one-call law reaches transmission facilities beyond natural-gas pipelines.",
  "incorporationCaveat": "Chapter PSC 135 adopts and supplements federal minimum pipeline-safety standards, principally 49 CFR Parts 191, 192, 193, and 199. The source also cites statutes, administrative rules, Commission forms and orders, and private technical standards. References are retained as metadata; incorporated material is not reproduced and its edition, legal effect, and licensing must be verified at the referenced source.",
  "rightsCaveat": "Official Wisconsin Legislature and Public Service Commission text is preserved with attribution and source hashes. Public availability does not establish a blanket license for site presentation, agency marks, annotations, forms, or incorporated federal and privately authored standards; downstream redistribution requires separate rights review.",
