levels when all emergency power generation equipment is running, including backup generators.

  1. The applicant shall provide a vibration study prepared by a qualified professional that demonstrates that no vibration from the Data Center, Data Center Accessory Uses, or associated equipment will be perceptible to the human sense of feeling beyond the property line, and to mitigate any negative impacts to wildlife and pollinator populations.
  2. Tonal noise penalty
  3. Each sound study shall include a narrow band frequency analysis for the purpose of identifying audible tones generated by the use. Audibility of tones shall be calculated in accordance with International Organization for Standardization Technical Specification (ISO/TS) 20065:2022 - Acoustics - Objective Method for Assessing the Audibility of Tones in Noise - Engineering Method.
  4. If the decisive audibility of any narrow-band averaged spectrum is 10 dB or more, a 6 dB penalty shall be applied to the overall A-weighted sound measurement for purposes of determining compliance with Paragraph (1) above.

H. Water and Sewer

  1. The use may utilize a closed-loop cooling system.
  2. The use shall deploy technologies for water conservation including, not limited to, installing closed-loop or recirculation systems to reduce demands on the water supply.
  3. If the use is served by a public water supply, the applicant shall submit documentation from the public authority certifying that the public authority will supply the water needed.
  4. If the use is to rely upon non-public sources of water, the applicant shall provide a water feasibility study. The purpose of the study is to determine if there is an adequate supply of water for the proposed use and to estimate the impact of the use on all existing wells, groundwater, and surface waters in the vicinity. No Data Center shall be approved unless the water feasibility study demonstrates that the anticipated water supply yield is adequate for the project and that the proposed water withdrawals and discharges will not endanger or adversely affect the quantity or quality of groundwater supplies or surface waters in the vicinity. The water feasibility study shall include the following information at a minimum:
  5. The projected water demands of the Data Center;
  6. The source of water to be used;
  7. A description of how water will be used, including the amount or proportion of water to be used for each purpose (e.g. cooling, humidity control, fire suppression, and domestic usage);
  8. The long-term safe yield of the water source;
