ST. PAUL, Minn. (AP) — The Minnesota Pollution Control Agency has postponed its recommendation on whether changes are needed to the state's water quality standards for protecting wild rice from sulfates.
The agency gave no explanation for canceling Thursday's scheduled release except to say it wasn't ready. MPCA spokesman Dave Verhasselt wrote in an email to reporters that the agency will provide an update when it can in the coming weeks.
Minnesota Public Radio reports (http://bit.ly/1bPkHYq ) that the Chamber of Commerce has criticized the study on which the MPCA is basing its recommendations. The Chamber's analysis concludes that based on the MPCA's study, a sulfate standard is unnecessary.
But John Pastor, a University of Minnesota Duluth researcher who's one of the lead researchers, says the current 10 milligrams-per-liter standard or something close is about right.
