An estimate of who lifts here. Each county goes to its nearest rack market with terminals; a market within 1.5 times that distance (or 25 miles more) shares it, up to 4 markets, weighted toward the closer one and the one with more terminals. Distances are straight-line from the county’s centre. Shares of a county always add to 100%, so the people counted across all markets add back to the U.S. total.

Fuel demand is an estimate: each state’s taxed gallons for the year (FHWA) are split among its counties by where the driving happens (EPA county vehicle miles, weighted by how much fuel each vehicle type burns), then shared to markets as above. Every state adds back to its FHWA total. Gasoline includes the ethanol blended into it; diesel is FHWA’s special fuels. Expect diesel to be least reliable along long-haul corridors, where trucks buy fuel in one county and burn it in another. Population: U.S. Census Bureau county estimates.

No pipeline tariff delivers here on file: the market depends on truck, rail or water, or its tariff has not been read.

Counts pipeline systems with a tariff delivery point here, not capacity, storage or contracts. A system with two lines into the market still counts once, and a terminal with one pipeline may also receive by truck, rail or water. For a refinery or pipeline outage across every market it touches, open that facility’s page.

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.
