Across 8 RRC districts, gathering through trunk to Nederland. One certified total for a statewide intrastate network, so any nameplate attached to it is a sum over dozens of segments and the ratio measures nothing. Its three cross-border rows are not an escape hatch: both exports are filed in D03 under facility 'Export from Louisiana', i.e. a shipper's injection at a boundary rather than the receiving line's throughput (DECISIONS.md 2.16-2.17).
