# Valero Three Rivers Refinery

Valero Three Rivers Refinery, Three Rivers, TX. 89,000 bpd crude capacity (EIA-820). Injects into NuStar Pipeline; reaches 8 delivery points and 26 terminals by published tariff. Crude supply, outlets, events.

- Location: Three Rivers, TX
- Status: active
- Crude capacity: 89,000 bpd (EIA-820)
- Operator: Diamond Shamrock Refining Co LP (a legacy legal-entity name; operated and branded today as the 'Valero Three Rivers Refinery')
- Parent: Valero Energy Corporation — Valero acquired Diamond Shamrock Refining & Marketing in 1997/2001-era corporate history and continues to operate the plant under the Valero brand; the 'Diamond Shamrock Refining CO LP' legal entity name in our graph/options is a stale, pre-rebrand name and should be treated as a Valero asset today.

## Pipelines it injects into
- NuStar Pipeline at Three Rivers, Live Oak County (Valero Three Rivers refinery) (same city) — https://thinkingonenergy.com/supply/pipeline/nustar-pipeline/

## Reach by published tariff route
| Pipeline | Delivery points | Terminals | Lowest ¢/bbl | Median ¢/bbl |

| NuStar Pipeline | 8 | 59 | 47.66 | 102.42 |

## Crude supply
- pipeline: Arrowhead System (ASTH — Arrowhead ST Holdings, LLC), operated by Harvest Midstream — A Dec 2024 Pipeline & Gas Journal item on Harvest Midstream's acquisition of full ownership of ASTH explicitly states the ~515-mile Eagle Ford gathering system 'delivers to numerous crude export docks and into Flint Hills Corpus Christi and Valero Three Rivers refineries.' This is a real, named Eagle Ford crude gathering/delivery system feeding this refinery, distinct from the long-haul Permian pipelines listed in our graph.
- truck: third-party trucking — A Jan 2025 fire report describes the refinery as having 'access to crude oil from West Texas and South Texas through third-party pipelines and trucks.'

## Product outlets
- pipeline: unspecified third-party pipelines — The same Jan 2025 item states the refinery 'distributes its refined petroleum products primarily through third-party pipelines' without naming them.
- truck_rack: Valero Three Rivers Refinery truck rack — Self-evident refinery-direct truck rack, consistent with our graph's own terminal-discovery record for this facility.

## Recent events
- 2025-01-01 — A large fire broke out and was extinguished at the Valero Three Rivers Refinery; no injuries were reported and the cause/extent of damage was not disclosed.
