INPUTS

Inputs includes those products that are processed by the refinery.

Crude Oil Inputs - Includes all refinery inputs of domestic and foreign crude oil to all processing units. It excludes any input of crude oil to be used in the manufacturing of finished petrochemicals within the refinery.

Total Inputs - Includes all refinery inputs charged to all processing units. Inputs can be crude oil, products of natural gas processing plants, unfinished oil net reruns, gasoline blending components, alcohols, hydrocarbons and hydrogen. Total inputs excludes any input to be used in the manufacturing of finished petrochemicals within the refinery.

Gross Input To Atmospheric Crude Oil Distillation Units - Reports only the inputs to the atmospheric crude oil distillation units.



PRODUCTS

Motor Gasoline - A complex mixture of volatile hydrocarbons with or without small quantities of additives, that has been blended to form a fuel mixture suitable for use in spark-ignition engines. Motor gasoline includes reformulated gasoline, oxygenated gasoline, and otherfinished gasoline. Gasoline blendstocks is not included until blending is completed.

    Reformulated - Gasoline formulated for use in motor gasoline the composition and properties which are certified as "reformulated gasoline" by the U.S. Environmental Protection Agency.

    Oxygenated (EPA Approved) - Gasoline formulated for use in motor vehicles that has an oxygen content of 1.8 percent or higher, by weight.

    Other Finished - Motor gasoline not included in the reformulated or oxygenated gasoline categories.

Blending Components - Motor gasoline blending components are composed of products such as straight-run gasoline, alkylate, reformate, benzene, toluene, and xylene.

Naphtha Type Jet Fuel - A fuel in the heavy naphtha boiling range. ASTM Specification D 1655 specifies for the fuel maximum distillation temperature of 290 degrees Fahrenheit at the 20 percent recovery point and 470 degrees Fahrenheit at the 90 percent point, meeting military Specification MIL-T-5624L (Grade JP-4).

Kerosene - Type Jet Fuel - A quality of kerosene product with a maximum distillation temperature of 400 degrees Fahrenheit at the ten percent boiling point and a final maximum boiling point of 572 degrees Fahrenheit. The fuel is used primarily for turbojet and turboprop aircraft engines.

    Commercial - Kerosene-type jet fuel intended for commercial use.

    Military - Kerosene-type jet fuel intended for military use.

Distillate Fuel Oil - A classification for the petroleum fraction produced in conventional distillation operations. The product is used for space heating, on-and off-highway Diesel engine fuel and electric power generation. Products included in this classification are No. 1, No. 2 and No. 4 fuel oils; No. 1, No. 2, and No. 4 Diesel fuels

    0.05% and under - This is distillate fuel that contains 0.05 % of sulfur or less.

    Greater than 0.05 % - distillate fuel in which the sulfur content is greater than 0.05%.



NET PRODUCTION

The net production of each product is equal to the refinery production of the product less refinery input of the product.



STOCKS

Reported stocks are those stocks in the custody of the refinery regardless of ownership and represent the actual measured inventories where an actual physical measurement is possible.
