Your action kit
Sourced arguments and ready-to-send letters — every figure links to a primary record. Edit to add your own story.
Demand a full, public review — not a rubber stamp.
Ask for an independent noise study, a water-and-power impact assessment, enforceable conditions (setbacks, hours, cooling type), and that the record stays open for written comment. Procedural shortcuts have voided approvals elsewhere.

Grid & water — why here
source: HIFLD · EPAThe closest existing grid infrastructure and the municipal water system this location sits in — the same constraints the buildout model screens on (it won't site a campus more than ~2 km from a substation or ~5 km from municipal water). Distances are straight-line to public HIFLD/EPA features, not a metered connection.

Tax breaks & subsidies
source: Good Jobs First / GASB 77No per-deal tax break is linked to this site yet. No state discloses the recipient of a data-center abatement at the facility level, so per-site deals are rare in the public record. If you have a development agreement or board resolution for this site, send it to us.
Water use
No public record of this facility's water use. We check state withdrawal reporting for self-supplied sites; municipally supplied sites only become visible through a public-records request to the local water utility — a per-facility request tool is coming. If you have a utility document for this site, send it to us.
