LAWRENCE, Kan. (AP) - Lawrence officials are studying how to pay up to $1 million to clean up a newly discovered landfill at the former Farmland Industries fertilizer plant. The Lawrence Journal-World reports (http://bit.ly/Lk6RS3 ) the city is working to convert the former plant site into a nearly 400-acre business park. The covered landfill was found a few months ago. Public works director Chuck Soules said the city is working with the Kansas Department of Health and Environment on the cleanup. Soules says the landfill isn't known to contain hazardous materials and holds mostly old office equipment, construction materials and other debris. Soules say the city hasn't yet received state approval to use money from an approximately $8 million environmental remediation account, funded by the now-defunct Farmland corporation.
