Winona County commissioners voted Tuesday to ban the highly contentious industry of frac sand mining, making it the first county in the state to take such a stand.
After a 40-minute discussion in front of a roomful of community members, the ban passed, 3-2.
Commissioner Marie Kovecsi, who voted for the ban, said there are seven frac sand operations and an active mine in her district.
"These operations are literally in my constituents' backyard," Kovecsi said. "The direct implications of noise and dust and road safety are faced by my constituents."
Sand mining in Minnesota and Wisconsin boomed and waned along with the oil and gas production practice known as hydrofracking.
The particular kind of sand found in parts of southeast Minnesota was in huge demand by exploration companies, which use it to prop open cracks in the underground shale formations that produce oil and natural gas.
Mining supporters in Winona County have said they're trying to protect private property rights, provide jobs and preserve the region's chance to cash in on changes in the nation's oil industry.
Commissioner Steve E. Jacob, who voted against the ban, said he wanted to find "common ground and compromise" by regulating the number of sand mines in the county, but despite approval by the planning commission, it was voted down by the majority County Board.
