February 16, 2010. Roquette America Inc. agreed to pay $1,000,000 in civil penalties for air pollution violations at Roquette’s corn wet milling facility in Keokuk, Iowa.

The state lawsuit alleged that Roquette violated air pollution control regulations by:

Roquette failed to implement required “best available control technology” and obtain a “PSD” permit when it made major plant modifications that increased air pollution emissions from several natural gas dryers. (“PSD” permits and requirements are designed to prevent significant deterioration when plants undergo major modifications.)

Roquette repeatedly exceeded its air pollution emission limitations under existing permits for particulate matter, nitrogen oxides, sulfur dioxide, volatile organic compounds, and carbon monoxide.
