Some residents are appealing the Winona County Board's decision not to require a detailed environmental review of a proposed frack sand mine.
In their appeal, the 12 residents contend the board failed to address potential cumulative effects of the proposed Nisbit mine in combination with other sand mines proposed in the area.
KAGE-AM reports the group also maintains the board failed to adequately consider and respond to comments from the public and state agencies.
Last month the board voted 3-2 not to require an environmental impact statement for the Nisbit mine. The proposed 20-acre mine site is located outside Utica and is in the center of a cluster of proposed mines.
Demand for silica sand is high because it's used in hydraulic fracturing, or "fracking," that produces oil and gas.
