Deere agrees to pay $1 million, complete audits over air quality violations


Deere & Co. has agreed to pay $1 million for violating air quality standards over a 12- to- 13-year period at its diesel-engine testing center in Cedar Falls, the Iowa Attorney General’s Office announced Thursday.

As part of a consent decree entered Thursday, Deere also agreed to conduct annual environmental audits by a third party for at least three years and until they receive two consecutive audit reports with no or minimal violations. 

In a petition, the Iowa Department of Natural Resources alleged that Deere had failed to comply with emissions limits in 80 construction permits at its Performance Engineering Center; had operated without proper air quality permits in some cases; had provided inaccurate information to the DNR from 2005 to 2016 on compliance reports; and had violated emissions limits on carbon monoxide, nitrogen oxides and particulate matter from 2005 until 2018.

Deere agreed not to contest the allegations as part of the settlement with the state.

“Deere’s violations went on far too long,” Attorney General Tom Miller said. “Even after the violations were discovered, the company continued to exceed emissions limits while it sought revised construction permits from the DNR to address its noncompliance.”
