Air Quality Construction Permit Issued for Aventine's Aurora West Facility

Notice to Proceed Issued to Contractor


PEKIN, Ill., Sept. 28, 2007 (PRIME NEWSWIRE) -- Aventine Renewable Energy Holdings, Inc. (NYSE:AVR), a leading producer, marketer and end-to-end provider of clean renewable energy, today announced that it has received an air quality construction permit for construction of its previously announced ethanol plant at Aurora, Nebraska.

The Nebraska Department of Environmental Quality ("NDEQ") issued the air quality construction permit on September 27, 2007. The permit allows for the eventual construction of a facility that will produce up to 226 million gallons annually of denatured fuel-grade ethanol. The initial phase 1 construction of 113 million nameplate gallons will begin immediately. A notice to proceed has already been issued to the contractor, Kiewit Energy Company. Phase 1 of the project also includes civil engineering site work for the phase 2 expansion. Phase 1 of the project is fully-funded. Aventine has already spent $55.4 million on the project through August, including amounts spent on license fees, the pre-purchase of long lead time plant equipment and initial site work in anticipation of receiving the air quality construction permit.

The plant site is located on 86 acres of land in Aurora, Nebraska, which is located approximately 75 miles west of Lincoln, Nebraska. The site is adjacent to an existing 50 million gallon ethanol facility operated by Nebraska Energy, LLC, of which Aventine is a majority partner/owner. The plant is being built by Kiewit Energy Company with Delta-T Corporation as the technology provider. Initial production from the plant is expected by the end of 2008.

In connection with the purchase of the land in 2006, Aventine signed agreements with the Aurora Cooperative relating to the development of the Aurora West site, which included the purchased land, and a grain supply agreement and a marketing agreement whereby the Aurora Cooperative would be the sole grain supplier for the new ethanol plant, as well as a marketer of the syrup and the sole marketer of wet distiller's grain with solubles produced by the facility. Nebraska Energy's existing grain supply and marketing arrangements with Aurora Cooperative were also extended.

Ron Miller, Aventine's President and Chief Executive Officer, said, "With today's permit from the NDEQ, we have now received the necessary air permits for both of our capacity expansions at Aurora and Mt. Vernon, IN. This puts us another step closer to more than doubling our nameplate ethanol production capacity from 207 million gallons annually to 433 million gallons annually." Miller continued, "We have a long history of working with the Aurora Cooperative, and we look forward to expanding upon that relationship with the new facility. As demand for ethanol continues to grow, the Aurora West complex will be important in helping to supply America's motor fuel needs."

George Hohwieler, President and CEO of the Aurora Cooperative, said, "We at the Aurora Cooperative want to congratulate Aventine on receiving their NDEQ air quality construction permit. This new ethanol facility, along with Nebraska Energy, makes this site one of the largest ethanol production complexes in the country. This complex will further assist farmers in our Cooperative in providing an additional outlet for their corn, thereby benefiting the entire region."
