Alternative Energy Sources Inc. has received the final go-ahead for its planned 110-million-gallon ethanol plant near Ogden, Iowa.

According to a news release, the Kansas City-based energy company said that the Iowa Department of Natural Resources approved an operational air permit for the plant so all permitting is now complete.

The Iowa Department of Economic Development has granted Alternative Energy Sources about $30 million in tax credits and tax abatement for the project.

The company also plans to build ethanol plants in Greenville and Kankakee, Ill.
