## Document text

§ 192.167 Compressor Station: Emergency ShutDown (a) Except for unattended field compressor stations of 1,000 horsepower (746 kilowatts) or less, each compressor station must have an emergency shutdown system that meets the following: (1) It must be able to block gas out of the station and blow down the station piping. (2) It must discharge gas from the blowdown piping at a location where the gas will not create a hazard. (3) It must provide means for the shutdown of gas compressing equipment, gas fires, and electrical facilities in the vicinity of gas headers and in the compressor building except, that: (i) Electrical circuits that supply emergency lighting required to assist station personnel in evacuating the compressor building and the area in the vicinity of the gas headers must remain energized; and (ii) Electrical circuits needed to protect equipment from damage may remain energized. (4) It must be operable from at least two locations, each of which is: (i) Outside the gas area of the station; (ii) Near the exit gates, if the station is fenced, or near emergency exits, if not fenced; and (iii) Not more than 500 feet (153 meters) from the limits of the station. (b) If a compressor station supplies gas directly to a distribution system with no other adequate source of gas available, the emergency shutdown system must be designed so that it will not function at the wrong time and cause the unintended outage on the distribution system.

  "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."
