(Linn County, IA) -- The Linn County Board of Supervisors is updating the rules for the county's utility-scale wind farms.
Changes include minimum setbacks of two times the height of wind turbines, limiting the noise level at the property line to 55-decibles, and ensuring the level is checked every five years.
The new rules also establish debris clean-up requirements, maintenance procedures, and encourages the use of local labor in construction and installation of renewable energy projects.
