Summary
Champaign County ties data center noise to state law. Zoning Ordinance Section 6.1.3 requires every DATA CENTER to comply with Illinois Pollution Control Board noise rules, and any data center sited within 1,500 feet of a dwelling must file a professional noise analysis before it can operate.
4. Noise levels from any DATA CENTER shall be in compliance with the applicable Illinois Pollution Control Board (IPCB) regulations (35 Illinois Administrative Code, Subtitle H: Noise, Parts 900, 901, 910). A. Any applicant located within 1,500 feet of a DWELLING shall submit a noise analysis by a qualified professional that demonstrates compliance with the IPCB noise regulations similar to the requirements of Section 6.1.5I.(3). The analysis shall include manufacturer’s sound power level characteristics and other relevant data regarding noise characteristics of proposed DATA CENTER equipment. B. Enforcement shall follow protocols established in Section 6.1.5 I.(4) of the Zoning Ordinance.
Full Breakdown
Section 6.1.3's Schedule of Standard Conditions attaches four numbered requirements to every DATA CENTER special use, and the fourth is the noise standard. It requires that noise levels from any DATA CENTER comply with the applicable Illinois Pollution Control Board regulations at 35 Illinois Administrative Code, Subtitle H: Noise, Parts 900, 901 and 910, incorporating the state's numeric noise limits rather than setting a separate county decibel cap.
The county adds a distance-triggered documentation requirement on top of that state standard: any applicant proposing a DATA CENTER located within 1,500 feet of a dwelling must submit a noise analysis prepared by a qualified professional demonstrating compliance with the IPCB regulations, modeled on the noise-analysis requirement the ordinance already applies to PV SOLAR FARM special uses under Section 6.1.5.I.(3). That analysis has to include the manufacturer's sound power level characteristics and other relevant data about the noise the proposed equipment will generate, giving Planning & Zoning something concrete to check the application against before it goes to the County Board.
Enforcement of a noise complaint after the facility is built follows the same protocol the ordinance sets for PV SOLAR FARM enforcement under Section 6.1.5.I.(4), so a data center that later runs louder than the IPCB limits allow is not just a paperwork failure at the permit stage; it stays actionable as an ongoing special use violation.
Violations & Fines
A DATA CENTER that fails to meet the state IPCB noise limits or was sited within 1,500 feet of a dwelling without filing the required noise analysis is out of compliance with its special use permit. That triggers Section 10 zoning enforcement: a written complaint, investigation by the Zoning Administrator, and a petty-offense fine up to $500, with each day the noise violation continues after notice standing as a separate offense.
