(Radio Iowa) – A 36-year-old man is charged with causing a diesel fuel spill near Dallas Center, at a site owned by his former employer. Aaron Wayne Peek of Des Moines is charged with theft, criminal mischief and trespassing. The Dallas County Sheriff says video footage from cameras at the site showed Peek, a former employee of the farm company, tampered with an above ground tank early Saturday morning, releasing four-thousand gallons of diesel fuel.

About 10-thousand dollars worth of diesel was spilled and it reached a creek near Waukee.

State officials estimate the environmental cleanup will cost over 100-thousand dollars.
