S.B. 1046: Data centers; noise abatement.

Data centers; noise abatement. Provides that any local government land use application required for the siting of a data center shall be approved only in accordance with certain notice and noise abatement requirements. The bill provides that residents within a half mile radius of the parcel shall receive notice of the proposed data center and that the data center operator shall hold two neighborhood meetings. The bill requires a data center operator to design and build the data center to incorporate sound mitigation methods sufficient to prevent the sound levels emanating from the data center from exceeding the ambient noise levels that were observed in a baseline study, as determined by a third party acoustic engineer. The bill also provides that upon issuance of a certificate of occupancy, and for five years thereafter, the data center operator shall conduct a noise study performed by a third party acoustical engineer to document noise levels emanating from the data center measured at the property line of the nearest property to the data center property that is planned or zoned for residential land uses, or other noise sensitive use as reasonably determined by the locality, during peak operation of the data center mechanical equipment. The bill also provides that if the data center operator intends to use backup power generators on the parcel, the operator shall maintain a public website announcing the times when the generators will be in operation. Finally, the bill provides that any noise ordinance adopted by a locality shall set maximum allowable sound levels for data centers, including by (i) using alternative low frequency noise metrics and (ii) setting noise rules and enforcement mechanisms in its zoning ordinance, separate from existing noise ordinances.
