§ 192.505 Strength Test Requirements for Steel Pipeline to Operate at a Hoop Stress of 30 Percent or More of SMYS (a) Except for service lines, each segment of a steel pipeline that is to operate at a hoop stress of 30 percent or more of SMYS must be strength tested in accordance with this section to substantiate the proposed maximum allowable operating pressure. In addition, in a Class 1 or Class 2 location, if there is a building intended for human occupancy within 300 feet (91 meters) of a pipeline, a hydrostatic test must be conducted to a test pressure of at least 125 percent of maximum operating pressure on that segment of the pipeline within 300 feet (91 meters) of such a building, but in no event may the test section be less than 600 feet (183 meters) unless the length of the newly installed or relocated pipe is less than 600 feet (183 meters). However, if the buildings are evacuated while the hoop stress exceeds 50 percent of SMYS, air or inert gas may be used as the test medium. (b) In a Class 1 or Class 2 location, each compressor station, regulator station, and measuring station, must be tested to at least Class 3 location test requirements. (c) Except as provided in paragraph (d) of this section, the strength test must be conducted by maintaining the pressure at or above the test pressure for at least 8 hours. (d) For fabricated units and short sections of pipe, for which a post installation test is impractical, a preinstallation strength test must be conducted by maintaining the pressure at or above the test pressure for at least 4 hours.

    "exactScope": "The searchable corpus contains every current numbered section, the code-wide definitions, and every operative appendix in official 23 CAR Part 500, plus direct pipeline rules 15 CAR sections 275-406 and 275-504. Reserved and removed provisions are inventory-only.",
    "excludedScope": "This is not all Arkansas pipeline law. Standalone statutes, dockets and orders, one-call law, utility rates and service, siting, environmental permits, highway crossings, local law, forms, and incorporated third-party standards are excluded. Other current AOGC gas and transportation rules are inventoried as adjacent production, conservation, storage, or fluid-transport material.",
    "applicabilityCaveat": "APSC administers certified intrastate gas safety downstream of producer custody transfer. AOGC section 275-406 separately reaches specified producer or producer-affiliated natural-gas systems. AOGC section 275-504 imposes state permitting and operational duties on specified hazardous-liquid pipelines, but PHMSA states that it directly inspects and enforces intrastate hazardous-liquid pipeline safety in Arkansas. Inclusion does not establish applicability to a particular facility.",
    "incorporationCaveat": "AOGC sections 275-406 and 275-504 use dynamic 'as amended' wording for federal Parts 190, 191, 192, 195, and 199. Part 500 is a state code that reproduces and modifies federal-derived gas provisions. References and relationship records do not substitute a retrieval-date federal text or decide the legal effect of incorporation.",
    "publicationCaveat": "The Code of Arkansas Rules identifies its online database as the official version, effective as a publication system January 1, 2025, updated weekly, and potentially behind recent agency rulemaking. The official Part 500 page reports Ark. R. 2026-6 effective January 8, 2026; its PDF is headed August 22, 2025 and Docket 25-025-R. Retrieval and site-update dates are publication observations, not inferred legal effective dates for every section.",
    "rights": "Official Arkansas and federal government artifacts are archived with attribution and SHA-256 provenance. Public access does not settle rights in seals, site presentation, forms, incorporated standards, or third-party material; downstream redistribution requires separate review."
