Big Muddy Speaker Series presents:
The Ins and Outs of Water at Power Plants on the Missouri River


Published: December 22, 2015
Presentation by Dr. Greg Howick, Senior Aquatic Ecologist at Burns & McDonnell Engineering Company, Inc.
Original Presentation, December 22, 2015 at Westport Coffeehouse Theater, Kansas City, MO.
When people think about important uses of the lower Missouri River, they often overlook the largest water user. The largest use of water from the river is for steam condensation (cooling) by power plants. Of the 15 active power plants on the river between Sioux City and St. Louis, 14 withdraw large quantities of water that are passed once through steam condensers then discharged back to the river 10 to 20 degrees Fahrenheit warmer.
The discharge of cooling water is regulated by state water quality standards and criteria and Section 316(a) of the Clean Water Act. The withdrawal of water by cooling water intakes is regulated by Section 316(b). In addition to compliance with these regulations, some power plant intakes are being impacted by a degrading river bed that has lowered water levels.
Dr. Howick will present highlights of the rules for power plant intakes and discharges, and describe the work he has done on the Missouri River to help power plant owners comply with these regulations.
