## Crude supply
- pipeline: Keystone Pipeline (via Port Neches Link) — The Port Neches Link Pipeline (in service March 2023, 4 mi/36in) was purpose-built for last-mile connectivity from Keystone/Marketlink's Nederland Delivery Station to Motiva's Port Neches terminal feeding the Port Arthur refinery.
- pipeline: Nederland Terminal dedicated crude line — RBN Energy describes a dedicated 30-inch crude pipeline from the Nederland terminal to the 600 Mb/d Motiva Port Arthur refinery.
- marine: Sabine-Neches Waterway — Deepwater channel access shared by the Beaumont/Port Arthur refining complex.
- pipeline: Enterprise ECHO Terminal (crude) — RBN describes ECHO as connecting to refiners in Houston, Pasadena, Texas City AND Beaumont/Port Arthur; the graph's 'products_pipeline' typing for this edge again looks like a type mismatch since ECHO handles crude.

## Product outlets
- pipeline: Colonial Pipeline — Colonial documents receiving product from Beaumont/Port Arthur refineries generally.
- pipeline: Explorer Pipeline — Explorer's Port Arthur origin historically served the Beaumont/Port Arthur refineries generally; Explorer's own connected-refinery list found in this research names Premcor (Port Arthur), ExxonMobil (Beaumont) and Valero (Texas City) explicitly but did not separately name Motiva -- plausible but not independently confirmed for Motiva specifically.
- pipeline: TEPPCO / Enterprise TE Products Pipeline — Regional TE Products network serves Beaumont/Port Arthur refineries; a Motiva-specific citation was not found within budget.
- truck_rack: Motiva Refinery rack — Refinery-direct truck rack is expected for a facility of this scale (275,000 bpd of branded fuel and 40,000 bpd of base oil produced daily per trade press).

## Recent events
- 2025-07 — Fire broke out in a heavy oil conversion unit near the plant's center; ~1,400 people were on site, all accounted for with no injuries; possibly lightning-related; other units remained operational.
- 2025-02 — Trade press reported Motiva had quietly expanded Port Arthur to 640,500-654,000 bpd, making it the largest single US/North American refinery.
- 2024-04 — Severe thunderstorms (with a tornado) caused a power outage that shut nine units, including two crude distillation units, which Motiva restarted overnight.
