Summary
Aurora, Illinois (Kane County) ties industrial-zone noise to Illinois EPA sound-pressure standards in its M-1/M-2 manufacturing districts, letting the state Noise Pollution Control Board, or the city after 90 days, enforce complaints.
Noise: Noise standards shall be those measurement and administrative procedures most recently adopted by the State of Illinois and enforced by the Illinois Environmental Protection Agency, Division of Land/Noise Pollution Control. All uses within this district shall not exceed the sound pressure levels as provided therein... In the event that the state does not investigate a complaint by measuring for noise compliance within ninety (90) days of registration, the city may proceed on its own to investigate the complaint using the State of Illinois Standards described above.
Full Breakdown
Under the M-1 and M-2 manufacturing district performance standards (Code §§ 49-109.2, 49-109.3), industrial uses anywhere in the city, including its Kane County core and the DuPage, Will, and Kendall County territory, may not exceed the sound pressure levels set by the Illinois EPA's Division of Land/Noise Pollution Control. Complaints go first to the State of Illinois Noise Pollution Control Board for hearing; if the state hasn't investigated within 90 days of registration, Aurora can measure and pursue the complaint itself. Where an M-2 industrial tract borders a residential district, the rule instead defaults to the stricter B-3 Business Wholesale District standard.
Violations & Fines
Failure to meet the state sound-pressure standard is a zoning violation, ruled on by the state Noise Pollution Control Board or the city after 90 days of state inaction.
