§ 191.22 National Registry of Pipeline and LNG operators (a) OPID Request. Effective January 1, 2012, each operator of a gas pipeline, gas pipeline facility, must obtain from PHMSA an Operator Identification Number (OPID). An OPID is assigned to an operator for the pipeline or pipeline system for which the operator has primary responsibility. To obtain on OPID, an operator must complete an OPID Assignment Request DOT Form PHMSA F 1000.1 through the National Registry of Pipeline in accordance with § 191.7. (b) OPID validation. An operator who has already been assigned one or more OPID by January 1, 2011, must validate the information associated with each OPID through the National Registry of Pipeline at http://portal.phmsa.dot.gov/pipeline, and correct that information as necessary, no later than June 30, 2012. (c) Changes. Each operator of a gas pipeline, gas pipeline facility must notify PHMSA electronically through the National Registry of Pipeline at http://portal.phmsa.dot.gov/pipeline of certain events. (1) An operator must notify PHMSA of any of the following events not later than 60 days before the event occurs: (i) Construction or any planned rehabilitation, replacement, modification, upgrade, uprate, or update of a facility, other than a section of line pipe that costs $10 million or more. If 60-day notice is not feasible because of an emergency, an operator must notify PHMSA as soon as practicable; (ii) Construction of 10 or more miles of a new or replacement pipeline; (iii) Construction of a new underground natural gas storage facility or the abandonment, drilling or well workover (including replacement of wellhead, tubing, or a new casing) of an injection, withdrawal, monitoring, or observation well for an underground natural gas storage facility. (iv) Reversal of product flow direction when the reversal is expected to last more than 30 days. This notification is not required for pipeline systems already designed for bi- directional flow; or (v) A pipeline converted for service under § 192.14 of this chapter, or a change in commodity as reported on the annual report as required by § 191.17. (2) An operator must notify PHMSA of any of the following events not later than 60 days after the event occurs: (i) A change in the primary entity responsible (i.e., with an assigned OPID) for managing or administering a safety program required by this part covering pipeline facilities operated under multiple OPIDs. (ii) A change in the name of the operator; (iii) A change in the entity (e.g., company, municipality) responsible for an existing pipeline, pipeline segment, or pipeline facility; or (iv) The acquisition or divestiture of 50 or more miles of a pipeline or pipeline system subject to Part 192 of this subchapter. (d) Reporting. An operator must use the OPID issued by PHMSA for all reporting requirements covered under this subchapter and for submissions to the National Pipeline Mapping System.

  "subject": "intrastate-gas",
  "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."
