The Wisconsin Department of Justice Obtains Judgment Against Interstate Energy Partners, LLC, and Tiller Corporation 

Defendants to Pay Forfeitures and Statutory Fees Totaling $80,000


MADISON — Attorney General J.B. Van Hollen has announced that his office has obtained a judgment in Burnett County Circuit Court against a frac sand mining operation.  Interstate Energy Partners, LLC (IEP), a Minnesota corporation, owns a sand and gravel mining facility in the Town of Grantsburg, in Burnett County, which is operated by Tiller Corporation, also of Minnesota. 


The civil complaint states that sometime between April 19 and April 22, 2012, a discharge of fine grained sediment ran into a wetland complex, into a creek, and downstream into the St. Croix River.  The St. Croix River is designated as an Area of Special Natural Resource Interest and part of the National Wild and Scenic Rivers System.  The Department of Natural Resources (DNR) discovered the discharge by responding to a citizen complaint on April 26, 2012, and production at the mining facility was immediately shut down.


Judgment has been entered for failure to maintain necessary dikes and berms and discharging outside the conditions of their permit, in violation of Wisconsin environmental protection laws.  Defendants will pay forfeitures and statutory fees totaling $80,000. 


“Wisconsin will continue to ensure our high quality rivers and streams are protected, and operators will be required to adhere to the laws and regulations designed to prevent pollution of our precious natural resources,” Attorney General Van Hollen said.


This case was referred to the Wisconsin Department of Justice by the DNR and prosecuted by Assistant Attorneys General Cynthia R. Hirsch and Diane L. Milligan.  The order was signed by Judge Kenneth Kutz on January 2, 2014.
