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.
Virginia reported $1B in Data Center Retail Sales and Use Tax Exemption (Va. Code § 58.1-609.3(18)) for FY2024 (Virginia Joint Legislative Audit and Review Commission (JLARC) / Weldon Cooper Center). Program-wide, not attributable to this site.
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.
EPA permits & violations
source: EPA ECHONo reported violations as of last sync.
What this site costs the grid
source: PJM RPM auction reportsPJM's capacity auction sets a $/MW-day price that utilities pass on to every household and business in the zone. This site sits in PJM's DOM pricing zone, where soaring data-center demand is a documented driver. See the full zone-by-zone breakdown →
Separately, a typical home in this zone pays an estimated $4 to $10/mo more on the capacity portion of its bill that PJM's market monitor attributes to data-center demand. See your address's full impact →
Nearest school
source: HIFLD / NCESThe nearest public school, Guilford Elementary in Sterling, is 1.9 mi from this site (541 students).
Schools are sensitive receptors for the noise, backup-generator exhaust, and traffic a large data center brings. Straight-line distance to the nearest public school (HIFLD/NCES, US public schools only).
