## Document text

§ 192.507 Test Requirements for Pipelines to Operate at a Hoop Stress Less Than 30 Percent of SMYS and at or Above 100 P.S.I. (689 kPa) Gage Except for service lines and plastic pipelines, each segment of a pipeline that is to be operated at a hoop stress less than 30 percent of SMYS and at or above 100 p.s.i. (689 kPa) gage must be tested in accordance with the following: (a) The test procedure used must reasonably ensure discovery of leaks in the segment being tested. (b) If, during the test, the segment is to be stressed to 20 percent or more of SMYS and natural gas, inert gas, or air is the test medium: (1) A leak test must be made at a pressure between 100 p.s.i. (689 kPa) gage and the pressure required to produce a hoop stress of 20 percent of SMYS; or (2) The line must be walked to check for leaks while the hoop stress is held at approximately 20 percent of SMYS. (c) The pressure must be maintained at or above the test pressure for at least 1 hour. (d) For fabricated units and short sections of pipe, for which a post installation test is impractical, a pre-installation hydrostatic pressure test must be conducted in accordance with the requirements of this section.

  "caveats": {
    "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."
