ST. PAUL, Minn. (WCCO/AP) — The Minnesota Supreme Court on Wednesday upheld Winona County’s ban on the mining and processing of silica sand, which is used in the oil and gas industry for hydraulic fracturing.
A divided high court affirmed a 2018 ruling from the Minnesota Court of Appeals, which rejected a challenge to the county’s 2016 ban filed by Minnesota Sands LLC. The company, which held five mining leases at issue in the case, argued that the ban was unconstitutional.READ MORE: FBI Warrants Say Twin Cities Organization Claiming To Feed Children Instead Spent Money On Cars, Trips, And Homes
But the Supreme Court agreed 4-3 with lower court rulings that Winona County’s ordinance was constitutional. The southeastern Minnesota county imposed the ban out of concerns about the environmental and health impacts of silica mining and processing.
Parts of southern Minnesota and western Wisconsin contain rich deposits of high-quality silica sand of the ideal size, hardness and purity for hydraulic fracturing. The sand acts as ball bearings to prop open cracks in underground rock to let oil and gas flow out.READ MORE: How Does Minnesota Cold Stack Up Against Other States?
“The destructive frac sand industry has no place in the kind of economy we need for our rural communities to thrive,” said Barb Nelson, a resident of Winona County and a member of the Land Stewardship Project who helped lead the campaign to pass the ban. “People took action to pass this ban because we understand that the land has inherent value, and that the health of the land and of people are interconnected. By destroying the land, we also harm ourselves.”
However the silica sand mining industry in the upper Midwest has struggled in recent years due to competition from cheaper sand mined closer to the oil fields of Texas and Oklahoma. While the Texas sand is of lower quality, lower transportation costs often make it more economical.MORE NEWS: Caitlin Clark Sets Big Ten Record As Iowa Women Rout Gophers
