Fees & terms
- Loss allowance
- Explorer/Magellan tariffs do not use a 'loss allowance' term; instead a volumetric TENDER DEDUCTION is applied (FERC No. 159.35.0, Item 30, Section B): 0.1% by volume on movements under Item 210 of FERC No. 166 (Port Neches/Port Arthur/Pasadena-Houston to Carthage/Mount Vernon/Rogers/Springfield); 0.15% by volume on movements under Item 300 of FERC No. 166 (Port Arthur to Albuquerque/Belen/El Paso/Santa Teresa) -- E.P.L. assesses 0.05% at the Port Arthur origin and MPL assesses the remaining 0.10%. No tender-deduction/loss-allowance figure was found in the Explorer local tariffs (100.134.0, 103.34.0, 101.29.0) or their rules and regulations sections. FERC No. 159.35.0 · Item 30

Fungible/joint batch: 25,000 bbl minimum for participation at origin; 100,000 bbl minimum on the mainline for Jet Fuel/Ultra Low Sulfur Diesel/Premium Gasoline and 50,000 bbl for all other products (Explorer local tariffs, Item 15). Stub lines: 5,000 bbl minimum.

Status & ownership
- Status
- Mainline runs from the Gulf Coast (Port Arthur/Port Neches/Mont Belvieu/Pasadena) via Dallas-Fort Worth and Tulsa to Wood River, IL and Hammond, IN. An extension to a new Melissa, TX (Collin Co.) delivery point came out of the Sept 2019 open season (Docket OR20-8, June 2020). Diluent volume-incentive service to Irwin/Cochin (Kankakee Co.) and Manhattan/Southern Lights (Will Co.), IL began no earlier than July 1, 2025 (Item 118). Explorer's website carries a news item about recovery from a tank fire at Glenpool, OK (date not verified). Explorer has NO Oklahoma City delivery point; the only Oklahoma point is Tulsa.
- Ownership
- Explorer Pipeline Company is a joint venture. MPLX's FY2025 10-K lists a 25% equity interest (Refined Product Systems: Explorer Pipeline Company, 10"-28", 1,872 miles). The other owners were not verified from operator documents in this pass. Explorer publishes joint tariffs with Marathon Pipe Line (103.34.0) and Phillips 66 Carrier (101.29.0), and participates in Magellan (ONEOK) joint tariffs 159.35.0/166.35.0 and Texas RRC joint tariff 54.31.0.
- Intrastate
- The Texas points Houston through Melissa carry '+' (intrastate application only) in 100.134.0. Explorer also posts Letter Tariff No. 4 Supp. 14 (TX-to-TX volume incentive) and Magellan/Explorer Texas No. 54.31.0 (RRC T-4 permits T-05754, T-09562); both read 2026-10-10: Letter Tariff No. 4 Supp. 14 has two rows, Dallas/Global and Fort Worth/Global, from Port Arthur/EPCo; Texas No. 54.31.0 has twelve Magellan destinations from Port Arthur (Dallas - Motiva, Dallas - MPL, East Houston - MPL, Hearne - Motiva, Pasadena - Motiva, Reagan, Waco - Motiva, El Paso - MPL, Frost - MPL, Odessa - MPL, Tye (Abilene), West Ft. Worth-MPL), which are Magellan deliveries and are not carried as Explorer points.

- HIGH confidence
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.
