Retired heavy industry
658 smelters, mills, refineries and mines that stopped EPA greenhouse-gas reporting. Large former loads often leave grid connections behind.

DOE cleanup sites
Five DOE cleanup sites split into land units, each rated for a data center, large reactor, SMR and microreactor.
Method. Our ratings from cited DOE, NRC and lease documents; each names its binding constraint. Anchored: signed lease, award or operating use. Strong: selected, not signed. Conditional: one named constraint. Precluded: legal or mission bar. Environmental layers: PNNL nepa-mcp.

Data & methods
Each ranking is a few pass/fail checks. Every threshold below is either an agency's own number or ours, and says which. Missing data never counts as a pass.
Limits
- Grid: distance to a mapped line or substation (HIFLD, OpenStreetMap) is not available capacity or a connection agreement.
- Water: an annual mean at a USGS gage is not drought flow, a permit or a water right. Distance to a gage is not distance to water.
- Land: most ACRES brownfields report no acreage (unknown). Superfund and FUDS areas that trace a county, region, river or plume are treated as unknown.
- Fiber: no parcel-level enterprise fiber data exists publicly, so fiber is not scored.
- Curated rows (coal projects, nuclear sites, DOE parcels) carry a source link and a verified date; the daily research routine re-checks sites over time.
