| crude in | pipeline | Front Range Pipeline Front Range Pipeline, LLC (MT) files a Montana crude petroleum tariff, P.S.C. No. 32, effective July 1, 2026, with rates from Cut Bank and from Santa Rita Station to Great Falls, Cascade County. The tariff names the destination as Great Falls and does not name the refinery. It serves the crude refinery, not the renewable fuels plant. |

| crude in | rail | Rail (renewable feedstock) Feedstock for the renewable fuels plant arrives on the rail line that runs along the south side of the plant. The plant received about 21 railcars of feedstock a day in 2024, rising to an average of 44 a day at full capacity. The DOE assessment places the BNSF Railway line to the south of the site. |

| products out | truck rack | Calumet Montana Refining truck loading rack (IRS terminal T-81-MT-4011) The refinery's state air permit #2161-40, final July 2025, lists gasoline truck loading with a vapor combustor unit and an asphalt and diesel loading rack. The IRS lists terminal T-81-MT-4011 under Calumet Montana Refining LLC at 1900 10th Street. A December 2024 DOE assessment says the plant shipped five truckloads a day of non-renewable fuel and planned a SAF truck loading station within the existing rack. |

| products out | rail | Rail loading at the plant Renewable diesel and SAF leave by rail for markets on the West Coast and in Canada (DOE assessment, December 2024). Renewable naphtha is loaded through the refinery's existing rail loading. The refinery's permit lists gasoline railcar loading and an asphalt and diesel loading rack. |

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.
