# HAR 6-77-14 Class locations **Citation:** HAR 6-77-14 **Type / status:** regulation / current **Agency:** Hawaii Public Utilities Commission **Effective:** 1994-09-03 **Published:** 1994-04-15 is determined by applying the criteria set forth in this section: The class location unit is an area that extends 220 yards on either side of the centerline of any continuous one- mile length of pipeline. Except as provided in subsections (d)(2) and (f), the class location is determined by the build ## Document text is determined by applying the criteria set forth in this section: The class location unit is an area that extends 220 yards on either side of the centerline of any continuous one- mile length of pipeline. Except as provided in subsections (d)(2) and (f), the class location is determined by the buildings in the class location unit. For the purposes of this section, each separate dwelling unit in a multiple dwelling unit building is counted as a separate building intended for human occupancy. (b) A Class 1 location is any class location unit that has ten or less buildings intended for human occupancy. (c) A Class 2 location is any class location unit that has more than ten but less than forty-six buildings intended for human occupancy. (d) A Class 3 location is: (1) Any class location unit that has forty-six or more buildings intended for human occupancy; (2) An area where the pipeline lies within 100 yards of either a building or a small, well -defined outside area (such as a playground, recreation area, outdoor theater, or other place of public assembly) that is occupied by twenty or more persons on at least five days a week for ten weeks in any twelve-month period. (The days and weeks need not be consecutive.) (e) A Class 4 location is any class location unit where buildings with four or more stories above ground are prevalent. (f) The boundaries of the class locations determined in accordance with subsections (a) through (e) may be adjusted as follows: (1) A Class 4 location ends 220 yards from the nearest building with four or more stories above ground; (2) When a cluster of buildings intended for human occupancy requires a Class 3 location, the Class 3 location ends 220 yards from the nearest building in the cluster; (3) When a cluster of buildings intended for human occupancy requires a Class 2 location, the Class 2 location ends 220 yards from the nearest building in the cluster.

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." }, "region": "HI" } ```
