## Crude supply
- pipeline: Wyoming / Rocky Mountain sweet crude gathering — HF Sinclair's own facility page states the refinery 'primarily runs sweet crude from Wyoming and the Rocky Mountain region' and is 'capable of running both domestic and Canadian synthetic crude.' This broadly supports the general concept behind the graph's Powder River Basin / DJ Basin-Guernsey inbound edges (Wyoming-sourced sweet crude, plus a Canadian-synthetic capability implying a Guernsey, WY-area interconnect), but the operator page does not name specific pipelines such as 'Powder River Basin Gathering,' 'Powder River / Wind River Basin Pipeline,' or 'DJ Basin / Guernsey Pipeline.'

## Product outlets
- truck_rack: HF Sinclair Casper Refining LLC (IRS terminal T-83-WY-4052) — The IRS terminal list has two records at the refinery address: T-83-WY-4052 for HF Sinclair Casper Refining LLC and T-83-WY-4058 for Holly Energy Partners - Operating L.P. The list does not say which of the two numbers covers the truck loading rack.

## Recent events
- 2022-03 — HollyFrontier completed its acquisition of Sinclair Oil Corporation's refining and marketing assets (agreed August 2021, ~$2.6B) and renamed itself HF Sinclair Corporation, becoming the parent for this refinery.
