# HAR 6-77-153 General requirements **Citation:** HAR 6-77-153 **Type / status:** regulation / current **Agency:** Hawaii Public Utilities Commission **Effective:** 1994-09-03 **Published:** 1994-04-15 of this subchapter require that an increase in operating pressure be made in increments, the pressure must be increased gradually, at a rate that can be controlled, and in accordance with the following: (1) At the end of each incremental increase, the pressure must be held constant while the entire ## Document text of this subchapter require that an increase in operating pressure be made in increments, the pressure must be increased gradually, at a rate that can be controlled, and in accordance with the following: (1) At the end of each incremental increase, the pressure must be held constant while the entire segment of pipeline that is affected is checked for leaks; and (2) Each leak detected must be repaired before a further pressure increase is made, except that a leak determined not to be potentially hazardous need not be repaired, if it is monitored during the pressure increase and it does not become potentially hazardous. (b) Records. Each operator who uprates a segment of pipeline shall retain for the life of the segment a record of each investigation required by this subchapter, of all work performed, and of each pressure test conducted, in connection with the uprating. (c) Written plan. Each operator who uprates a segment of pipeline shall establish a written procedure to ensure compliance with each applicable requirement of this subchapter. (d) Limitation on increase in maximum allowable operating pressure. Except as provided in section 6-77-154(c), a new maximum allowable operating pressure established under this subchapter may not exceed the maximum that would be allowed under this chapter for a new segment of pipeline constructed of the same materials in the same location.

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" } ```
