A western Wisconsin city that annexed land from neighboring townships in an effort to entice a large frac-sand mine could see its gambit reversed by state officials in a case that has the potential to discourage the spread of similar mining projects across the state.
The so-called "balloon-on-a-string'' annexation — in which the city of Independence claimed authority over a long, narrow strip of land to extend its boundary to a large mining site miles away — was too arbitrary and irregular to meet state legal tests, the Wisconsin Department of Administration concluded. The annexation, which was designed in connection with a project by Texas-based Superior Silica Sands, would have placed the mine under city jurisdiction and exempted it from environmental regulation by Trempealeau County.
Jack Speerstra, chairman of the board in Lincoln Township, said he hopes the Oct. 6 ruling has a chilling effect on other Wisconsin cities that are contemplating far-reaching annexations.
"I hope this sends a message to city councils that they can't just do these annexations at will,'' Speerstra said.
The case has drawn attention from regulators and environmentalists across Wisconsin, in part because several other "balloon-on-a-string'' annexation plans are under consideration in Trempealeau County.
Located across the Mississippi River from Winona, Minn., the county already is one of the leading frac-sand jurisdictions in Wisconsin.
Jimmy Parra, a staff attorney for Madison-based Midwest Environmental Advocates, said the state's review addresses a growing problem. Wisconsin cities have broad powers to annex land without the consent of bordering townships, and they are taking advantage of the process to reap money from sand mining, he said.
"Hopefully, the agency's opinion will serve as a warning to other cities rushing to annex these mines for tax benefits at the expense of nearby residents' quality of life, air and water protections,'' Parra said.
