| products out | pipeline | Sweeny to Pasadena Pipeline Phillips 66 Carrier LLC tariff FERC No. 5.21.0, effective July 2026, runs from Sweeny, Brazoria County to Pasadena, Harris County and is limited to gasoline, NGL products and distillates. The tariff names the town, not the refinery. The line delivers to the Phillips 66 Pasadena terminal (IRS T-76-TX-2811), where the carrier's specification sheet lists Colonial, Explorer and Magellan grades and the Pasadena rack. |

| products out | rail | Union Pacific Petroleum coke moves by conveyor from the refinery to the Kinder Morgan Sweeny Terminal and leaves by unit train, with rail access from the Union Pacific. The state air permit for the refinery also covers railcar racks, and the company says products are distributed by railcar. Which products load into railcars is not stated. |

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.
