The plain version

Deer Park refines fuel for the country and pays for it at the pump like everyone else. The Deer Park refinery and its Ship Channel neighbors sit inside or against the city, which ties the town's revenue, its air, and its emergency planning to the making of fuel — even though the price you pay is set by global markets, not by anyone in town. The local handle on gasoline is mostly about the plants that make it, not the price you pay for it.

This page separates the two: the part of gasoline that is genuinely local — a refinery that is a major taxpayer and a permitted emitter, governed through the same TCEQ permits and industrial-district agreements as the other plants — from the part that isn't, the pump price set far upstream. Where a number goes on the page, its source is named; unsourced figures don't appear.
