§ 192.171 Compressor Stations: Additional Safety Equipment (a) Each compressor station must have adequate fire protection facilities. If fire pumps are a part of these facilities, their operation may not be affected by the emergency shutdown system. (b) Each compressor station prime mover, other than an electrical induction or synchronous motor, must have an automatic device to shut down the unit before the speed of either the prime mover or the driven unit exceeds a maximum safe speed. (c) Each compressor unit in a compressor station must have a shutdown or alarm device that operates in the event of inadequate cooling or lubrication of the unit. (d) Each compressor station gas engine that operates with pressure gas injection must be equipped so that the stoppage of the engine automatically shuts off the fuel and vents the engine distribution manifold. (e) Each muffler for a gas engine in a compressor station must have vent slots or holes in baffles of each compartment to prevent gas from being trapped in the muffler.

  "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."
