San Antonio Refinery

The San Antonio Refinery LLC · Traced through several owners: originally NuStar Refining, LLC / NuStar Logistics, L.P. (a NuStar Energy subsidiary) -> sold to Calumet Specialty Products Partners, L.P. for ~$115M in a deal signed Dec 2012 and closed Jan 2013 -> Calumet sold the refinery and related crude terminal/pipeline assets to 'Starlight Relativity Acquisition Company' for $63M, effective Nov 1, 2019. No source found this session that directly documents 'The San Antonio Refinery LLC' as Starlight's renamed operating entity, but the entity name and Calumet's 2019 divestiture are strongly consistent with it being the post-2019 owner/operator name; treat this linkage as a well-supported inference rather than a directly confirmed fact. · San Antonio, TX

crude in pipeline Karnes North Pipeline System (KNPS), operated (as of the Calumet era) by TexStar Midstream Logistics, L.P.
Per Calumet's own 10-K-era disclosures, the refinery received at least 12,000 bpd of light Eagle Ford crude via KNPS into its Elmendorf terminal (~188,000-200,000 bbl storage), then onward to the refinery. This is a TexStar Midstream system, not a NuStar-branded pipeline, despite NuStar's earlier (pre-2013) ownership of the refinery itself.

Rates are pipeline line-haul transcribed from published FERC tariffs; every figure cites its tariff and item. Cost to serve (netback) adds origin spot price and destination fees. "Confirmed" links match a tariff delivery point to the facility; "same city" means the point is in the facility's city — plausible, not proof; "per research" means the facility's research profile names the pipeline as an outlet.
