1971. Each aboveground pipeline or portion of a pipeline installed after July 31, 1971 that is exposed to the atmosphere must be cleaned and either coated or jacketed with a material suitable for the prevention of atmospheric corrosion. An operator need not comply with this paragraph, if the operator can demonstrate by test, investigation, or experience in the area of application, that a corrosive atmosphere does not exist. (b) Pipelines installed before August 1, 1971. Each operator having an above-ground pipeline or portion of a pipeline installed before August 1, 1971 that is exposed to the atmosphere, shall: (1) Determine the areas of atmospheric corrosion on the pipeline; (2) If atmospheric corrosion is found, take remedial measures to the extent required by the applicable paragraphs of sections 6-77-139, 6-77-140, or 6-77-141; and (3) Clean and either coat or jacket the areas of atmospheric corrosion on the pipeline with a material suitable for the prevention of atmospheric corrosion.

  "caveats": {
    "exactScope": "Complete substantive text of the Hawaii Public Utilities Commission publication of HAR Chapter 6-77: 196 non-reserved numbered sections and Appendices A through D. Four expressly reserved section slots are inventory-only. The PUC's April 2026 page links a 160-page signed scan; an official 178-page text-layer copy from Budget and Finance is used as the higher-quality transcription aid. The publication is an April 15, 1994 adoption, filed August 24 and effective September 3, 1994, based on the October 1, 1990 federal text; it is not a current restatement of federal pipeline standards.",
    "applicability": "Hawaii is not represented as certified, as an agreement state, or as an interstate agent under the PHMSA federal-state pipeline safety program. PHMSA states that its Office of Pipeline Safety inspects and enforces federal pipeline safety regulations for interstate and intrastate gas and hazardous-liquid pipelines in Hawaii. Chapter 6-77 may remain relevant as published state utility material, but it must not be used to infer current Hawaii inspection or enforcement authority.",
    "currentness": "The Hawaii PUC still links Chapter 6-77 on its official rules page, updated April 2026. Hawaii's official 2022 periodic rules-review report separately says Chapter 6-77 is to be repealed, was superseded by statute and a federal takeover letter, and cites 2009 Act 25. Because the PUC page does not mark the chapter repealed, this connector preserves the published text with an explicit superseded/slated-for-repeal warning rather than declaring an unproved completed administrative repeal.",
    "incorporation": "The chapter repeatedly identifies the October 1, 1990 edition of 49 CFR Parts 191 and 192 and its appendices as the implemented source. That fixed, obsolete baseline is preserved exactly. Current federal text, later amendments, and current editions of incorporated private standards must not be silently substituted when researching what this publication says.",
    "excludedScope": "This connector excludes HAR Chapter 6-83 one-call damage prevention, utility rates and service standards, statutes as standalone documents, dockets, orders, tariffs, federal text, current federal amendments, and the full text of incorporated private standards. Those materials require separate completeness, currentness, applicability, and rights analysis.",
    "rights": "Official Hawaii and PHMSA artifacts are retained with attribution and SHA-256 provenance. Public access does not establish unrestricted rights in site presentation, state marks, forms, or incorporated private standards. The connector records citations to private standards but makes no independent rights claim for those works."
