# HAR 6-77-111 Service lines: installation **Citation:** HAR 6-77-111 **Type / status:** regulation / current **Agency:** Hawaii Public Utilities Commission **Effective:** 1994-09-03 **Published:** 1994-04-15 installed with at least twelve inches of cover in private property and at least eighteen inches of cover in streets and roads.

(b) Support and back ## Document text installed with at least twelve inches of cover in private property and at least eighteen inches of cover in streets and roads. However, where an underground structure prevents installation at those depths, the service line must be able to withstand any anticipated external load. (b) Support and backfill. Each service line must be properly supported on undisturbed or well-compacted soil, and material used for backfill must be free of materials that could damage the pipe or its coating. (c) Grading for drainage. Where condensate in the gas might cause interruption in the gas supply to the customer, the service line must be graded so as to drain into the main or into drips at the low points in the service line. (d) Protection against piping strain and external loading. Each service line must be installed so as to minimize anticipated piping strain and external loading. (e) Installation of service lines into buildings. Each underground service line installed below grade through the outer foundation wall of a building must: (1) In the case of a metal service line, be protected against corrosion; (2) In the case of a plastic service line, be protected from shearing action and backfill settlement; and (3) Be sealed at the foundation wall to prevent leakage into the building. (f) Installation of service lines under buildings. Where an underground service line is installed under a building: (1) It must be encased in a gas-tight conduit; (2) The conduit and the service line must, if the service line supplies the building it underlies, extend into a normally usable and accessible part of the building; and (3) The space between the conduit and the service line must be sealed to prevent gas leakage into the building and, if the conduit is sealed at both ends, a vent line from the annular space must extend to a point where gas would not be a hazard, and extend above grade, terminating in a rain and insect resistant fitting.

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" } ```
