LEAVENWORTH, Kan. (AP) — The city of Leavenworth will be required to spend $85,000 for violating the federal Clean Water Act.

The payments come after the Environmental Protection Agency documented 19 sewer overflows between 2010 and 2015 from the city’s water treatment plant near the Missouri River. The overflows sent sewer water into the river.

The Topeka Capital-Journal reports the city must pay $46,200 in penalties and spend $38,800 for improvements to its storm water system.

Leavenworth spokeswoman Melissa Bower says the city had already planned a project to improve its storm water system before the EPA’s report.

The EPA at first proposed $104,000 in penalties and costs but reduced the amount after talking with city officials.
