assessing stormwater runoff at an industrial site

assessing stormwater runoff at an industrial site
Commercial Metals Company

innovative use of common analysis techniques saves money

Commercial Metals Company, a metal-recycling facility, sits along Jordan Creek in Springfield, Missouri. When the creek’s classification changed—prompting more stringent discharge limits that would require treatment of significant quantities of runoff—Commercial Metals turned to Barr for help.

Employing modeling techniques typically used for watershed-level planning, including drainage-area ratios and load-duration curves, Barr was able to show that the facility’s discharges did not exceed Jordan Creek’s loading capacity for multiple pollutants.

DNR staff members liked this approach but weren’t convinced until seeing the results. The revised permit helps protect Jordan Creek and will allow Commercial Metals to continue doing business at the existing site, saving thousands of dollars and enabling it to continue providing local jobs and affordable recycled metal for other businesses in Missouri. The project won a 2018 Honor Award for Engineering Excellence from the American Council of Engineering Companies of Missouri.
