At an open meeting held Thursday at the Public Service Commission of Wisconsin, commissioners discussed the the text of the proposed wind siting rule.
Commissioner Lauren Azar suggested a setback of 2200 feet from homes unless a developer can prove a turbine could be sited closer to a residence and still meet noise and shadow flicker standards.
She said the setback distance was based on information from PSC staff which indicated a 45dbA noise standard would be met at that distance.
However, Commissioner Azar also noted that the World Health Organization recommends 40 dbA as a nighttime noise standard, and indicated was the noise limit she preferred.
Residents under contract with developers could waive all standards and have turbines placed as close as 1.1 times the turbine height to their homes.
Chairman Callisto and Commissioner Meyer didn't offer their immediate opinions on Azar's suggestions.
Continued discussion of wind siting rules is scheduled for Monday.
