Locals used to call it the smell of money. The South St. Paul stockyards and the strong animal odor that accompanied them were defining elements of this blue-collar community.
The last of the stockyards closed in 2008, and many assumed the smell would leave with it. But this past spring and summer, residents complained of a pungent odor wafting into neighborhoods as many as five nights a week.
A handful of South St. Paul businesses that process animal products were suspected of causing the stink. Initially, there was finger-pointing amongst the businesses, city staff said. Now, four have joined forces to root out the problem, they've told the city.
The businesses call themselves the "odor consortium." With a nod from the city, they have agreed to investigate complaints and take odor measurements for a year's time. The group has set up a phone hotline and website so residents can lodge complaints.
The businesses are using an outside environmental consulting firm and have agreed to share their data with the city.
"Track back the history of this community and smell has always been associated with it," said South St. Paul City Administrator Steve King. "People assumed it was from having stockyards here. With the disappearance of that industry, there was a tacit assumption when those facilities were gone, the smell would disappear. And it hasn't."
The consortium businesses are ground beef producer Dakota Premium Foods, Twin City Hide, Twin City Tanning and Sanimax, a rendering company. The four businesses and their attorney could not be reached for comment.
They city has registered 62 smell complaints in 2012, well above the handful they usually receive, said city planner Peter Hellegers. There were a higher concentration of complaints from southside residents, but they came in from all over the city.
