| crude in | pipeline | Silvertip Pipeline Operated by Par Rocky Mountain Midstream, LLC. Its tariff F.E.R.C. No. 1.1.0, effective 2024-07-01, sets rates from Silver Tip, Edgar and Laurel, Montana to Billings, Montana. The tariff names the town, not the refinery. |

| products out | truck rack | Par Montana, LLC Billings Bulk Distribution Terminal (T-81-MT-4007) The terminal's 2023 state air permit says products made in the refinery are pumped to the terminal for storage or loaded into cargo tank trucks. It lists motor gasoline, two grades of aviation gasoline, jet fuel, several grades of diesel and heating oil, plus ethanol. The refinery's own permit also lists a truck loadout (west rack) with the polymer modified asphalt unit. |

| products out | pipeline | Yellowstone Pipeline Not independently confirmed this session -- ExxonMobil's facility page returned 404 and no substitute source was fetched. Included based on the graph's existing edge and general industry knowledge that the Yellowstone Pipeline system serves Billings-area refineries for outbound refined-products movement; this is NOT a fresh citation. |

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.
