(NNCNOW.com) --- Researchers say they need a few more months to determine if changes need to be made to wild rice sulfate standards in Minnesota.
State law limits the amount of sulfate that can be discharged into wild rice producing waters.
The Minnesota Pollution Control Agency announced today it will review and evaluate results of a 2-year study, through February.
They are working to determine if a change in the sulfate standard is warranted, and if so what changes would be needed.
"It’s our hope that this research will provide new information that protects wild rice and allows not only iron mines but other industries and municipalities that have permits, that they can move forward in their permitting process based on sound science,” Craig Pagel, President of the Iron Mining Association said.
An expert panel will review study results and preliminary recommendations in the spring of 2014.
