- Cooling method and water use
- The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
- Tax abatements or other public subsidy
- The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
