A private construction company hired by the Iowa Department of Transportation to work on a section of Interstate 35 in Clarke County has agreed to pay a $60,000 civil penalty to the U.S. Environmental Protection Agency (EPA) for performing unpermitted fill activities that affected a section of White Breast Creek and three acres of adjacent wetlands. Manatt’s Inc. of Brooklyn, Iowa, did not have a permit from the U.S. Army Corps of Engineers to perform fill work at the site in June or July of 2009, according to an administrative consent agreement filed by EPA Region 7 in Kansas City, Kan. The company is now working with the EPA and the Corps to develop a restoration and mitigation plan for the site.
