  "caveats": {
    "exactScope": "Bounded current direct pipeline-safety corpus of 36 sections in New Hampshire Administrative Rules Chapter En 500, effective October 25, 2023. It includes governing scope, safety-defined terms, emergency and incident duties, pipeline standards, safety records and maps, accidents and leaks, directly associated forms, and enforcement for gas pipeline utilities.",
    "excludedScope": "This is not all New Hampshire gas or pipeline law. Seventy-nine current En 500 sections concerning service, gas quality, meters, general accounting, supply, federal filings, or specialized LPG and landfill-gas programs are inventoried but not searchable. En 511 and En 512 are adjacent because the official PHMSA evidence proves intrastate-gas certification generally but does not independently establish that every state-defined LPG or landfill operator falls within that certification. En 800 damage prevention, En 1400 pipeline-utility economic regulation, statutes, forms, orders, federal text, private standards, interstate gas, hazardous liquids, and underground storage are excluded.",
    "applicability": "Applicability depends on operator and utility status, commodity, facility, activity, intrastate or interstate status, PHMSA and FERC jurisdiction, master-meter and LPG thresholds, waivers, orders, and the text in force on the relevant date. PHMSA states that New Hampshire is certified for intrastate gas; PHMSA retains interstate gas and both intrastate and interstate hazardous-liquid inspection and enforcement. The connector does not infer hazardous-liquid or underground-storage certification.",
    "incorporation": "En 506.01 requires compliance with 49 CFR Parts 191, 192, 193, 198, and 199, including future amendments, and contains additional state requirements and incorporated private standards. The rule does not state a fixed federal edition. This connector links but does not reproduce federal or private standards and does not decide whether every later federal amendment is validly incorporated for every state-law purpose.",
    "publication": "The New Hampshire General Court administrative-rules publication is the controlling current text used here. Document #13796 adopted En 500 effective October 25, 2023. The official Puc 500 revision note confirms that former PUC safety provisions were deleted and transferred to En 500; Puc 500 is not treated as parallel current safety text. Retrieval time is publication observation, not a legal event.",
    "rights": "Official New Hampshire and federal government artifacts are retained with attribution and SHA-256 provenance. Public access does not resolve rights in site presentation, seals, agency marks, forms, linked works, or incorporated private standards; downstream redistribution requires separate review."
