In this policy memo, Sarah Mills and Madeleine Krol address the Michigan Public Service Commission’s proposed acoustic guidelines for renewable energy developments. They draw upon data in the “past workable ordinances” database to demonstrate the uniqueness of PA 233’s reference to measurement of sound at the outer wall. They further recommend incorporating pre- and post-construction sound monitoring protocols into project applications to ensure a comprehensive understanding of noise impacts. Their feedback also emphasizes the importance of clear noise monitoring and complaint resolution protocols, including which party is responsible for paying for sound monitoring.
