MADISON, Wis. (AP) — Wisconsin regulators have relaxed noise restrictions on a major wind farm in St. Croix County.
The Public Service Commission approved the Highland wind farm in 2013, but a St. Croix County judge ruled the commission improperly imposed noise restrictions on the farm’s turbines. The restrictions required the turbines to remain within maximum decibel levels 95 percent of the time, or just under 23 hours per day.
The judge sent the matter back to the PSC for review. The panel voted 2-0 Thursday to remove the restrictions and require Highland to comply with a complaint resolution process and abide by noise limits in state regulations — 50 decibels during the day and 45 decibels at night.
The $250 million project calls for 44 turbines spread across more than 6,000 acres.
