Q: If undenatured fuel ethanol (product code 191) is produced only for the purpose of creating denatured fuel ethanol, should it be reported?

A: No. This production is considered an intermediate step. Only fuel ethanol that is intended for shipment (either denatured or undenatured) should be reported.

Q: How should undenatured fuel ethanol stocks be reported?

A: Undenatured fuel ethanol (product code 191) stocks should not be reported if it is in a "batch tank" or other very short-term storage as part of the production process of denatured fuel ethanol (product code 190). However, report stocks of undenatured fuel ethanol if it is stored on the premises awaiting final addition of denaturant when ready to ship.

Q: If we are shipping out undenatured fuel ethanol, should this production be reported?

A: Yes. Report any fuel ethanol production that is intended for shipping.

Q: Should production or stocks intended for export be reported?

A: Production for the export market and stocks intended for export are to be reported.

Q: What is Nameplate Capacity?

A: Nameplate Capacity is equal to Design Capacity for which the plant was built and is the volume of ethanol that can be produced during a period of 12 months under normal operating conditions.

Q: What is Maximum Sustainable Capacity?

A: In Part 3 of the form - Maximum Sustainable Capacity is the annualized maximum denatured fuel ethanol production that can be achieved over a period of any 6 consecutive months.

Q: How does one calculate the Maximum Sustainable Capacity?

A: Consider a fuel ethanol plant with the Nameplate Capacity equal to 100 million gallons per year that produced 55 million gallons during a period of 6 consecutive months. In this case, Maximum Sustainable Capacity would be 110 million gallons per year. (Take the best 6 consecutive months and multiply by 2.)

Q: How does one calculate the Semi Annual Storage Capacity Supplement?

A: The Annual Storage Capacity Supplement is Code 141 which equals product Code190 (Denatured Fuel Ethanol) + product Code191 (Undenatured Fuel Ethanol).

Q: What is Shell storage capacity?

A: Shell storage capacity is the design capacity of storage tanks. Shell storage capacity includes capacity of tanks in operation and under certain conditions idle tanks.

Q: What is Working storage capacity?

A: Working storage capacity is capacity above tank bottoms and below safe-fill capacity. Working storage capacity is reported only for tanks in operation.
