| Production                                           | Petroleum products produced at a refinery, natural gas processing plant, or blending plant. Published production equals production minus input. Negative production will occur when the amount of a product produced during the reporting period is less than the amount of that same product that is reprocessed (input) or reclassified to become another product during the same reporting period.                                                                                                                                                                                                                                                                                                                                                                                                     |
| Reformulated (Blended with Alcohol)                  | Reformulated gasoline blended with an alcohol component (e.g. fuel ethanol) at a terminal or refinery to raise the oxygen content.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           |
| Reformulated Gasoline (RFG)                          | Finished gasoline formulated for use in motor vehicles, the composition and properties of which meet the requirements of the reformulated gasoline regulations promulgated by the U.S. Environmental Protection Agency under Section 211(k) of the Clean Air Act. It includes gasoline produced to meet or exceed emissions performance and benzene content standards of federal-program reformulated gasoline even though the gasoline may not meet all of the composition requirements (e.g. oxygen content) of federal-program reformulated gasoline. Reformulated gasoline excludes Reformulated Blendstock for Oxygenate Blending (RBOB) and Gasoline Treated as Blendstock (GTAB). Historical reformulated gasoline statistics included Oxygenated Fuels Program Reformulated Gasoline (OPRG).  |
| Sulfur                                               | A yellowish nonmetallic element, sometimes known as "brimstone." It is present at various levels of concentration in many fossil fuels.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      |
