Noise modeling shows operational compliance with Illinois limits; construction noise not modeled
Oct 28, 2026
An acoustical engineer hired by the applicant reported that modeled operational noise from inverters and the substation meets Illinois Pollution Control Board octave‑band limits at nearby residences and cemetery, while acknowledging construction noise was not modeled and is regulated differently.
The full story
Michael Conaway, an acoustical engineer, presented a three‑dimensional noise model for the project and said the main operational noise sources are inverter stations and the substation transformer. "On a very high level, the highest sound received at nearby residents during the day is 50... dBA," he said, and added his analysis "shows that there is compliance with the daytime and nighttime octave frequency band sound levels that the IPCB requires."
