EVIDENCE REGISTER / ETV-CEI-1.0
A concern is a starting point. A finding requires evidence.
Selected records, not an exhaustive incident inventory. Colors describe documented follow-up status—not community health, facility safety, or ethical certification.
Legend totals describe the complete reviewed register. Filters below narrow the map and results. No record means a coverage gap; it does not mean no concern.

Status evidence: Sep 14, 2026Reviewed: Sep 27, 2026Recheck after: Oct 14, 2026
Evidence context & limitations
Basis. A dated agency notice documents a formal proposed enforcement action whose comment period remained open on the review date.
Interpretation. Reviewed authority evidence documents an action requiring follow-up. This is not a finding of health harm or a facility-wide risk score.
Limits. The notice concerns a proposed order, not a final adjudication; it does not establish exposure, injury, environmental causation, or the present safety of the facility.
CyrusOne reports ongoing Aurora sound-mitigation work
Aurora · Ongoing sound-mitigation work at CyrusOne’s Aurora CHI2 and CHI3 buildings.
The City of Aurora documented neighborhood noise complaints in 2025; CyrusOne’s September 24, 2026 update reports continued installation of chiller attenuators at Building 2 and sound-mitigation louvers at Building 3.
NoiseCommunity engagement
Status evidence: Sep 24, 2026Reviewed: Sep 27, 2026
Evidence context & limitations
Basis. The latest operator update describes remaining work, while the municipality independently documents the earlier concern; no full resolution is established.
Interpretation. A source documents a concern, proposal, or review. An allegation is not a confirmed impact.
Limits. Progress is operator-reported and is not a verified post-mitigation acoustic result or evidence that all neighborhood complaints are resolved.

Google reports completion and transfer of a water-storage project
The Dalles · The named aquifer storage and recovery infrastructure project associated with Google’s The Dalles investment.

Water resourcesCommunity engagement
Status evidence: Oct 22, 2025Reviewed: Sep 27, 2026
Evidence context & limitations
Basis. An operator reports a completed infrastructure milestone, but no independent municipal confirmation of completion or measured local water outcome was verified for this record.
Interpretation. The reviewed evidence does not support an action-state classification.
Limits. Operator announcement only; not independent verification of recovery volumes, net basin water benefit, groundwater impacts or resolution of local water concerns. This record does not qualify for a Green signal.
AEP Ohio service territory · The AEP Ohio tariff proceeding, case 24-508-EL-ATA; not every Ohio utility or a finding against a specific facility.
The Public Utilities Commission of Ohio adopted a settlement and ordered AEP Ohio to file data-center tariffs intended to protect other customers from the cost of underused infrastructure investments.
Energy & affordabilityCommunity engagement
Status evidence: Jul 9, 2025Reviewed: Sep 27, 2026
Evidence context & limitations
Basis. The regulator announced an adopted order addressing cost-allocation risk, rather than a proposed operator pledge.
Interpretation. The dated status evidence is missing or more than 365 days old. A new review date alone cannot refresh it.
Limits. An adopted tariff safeguard is not measured proof of household bill savings or elimination of future cost shifting. The dated decision is historical under the dashboard freshness rule.
Virginia DEQ withdraws a proposed data-center generator variance
Loudoun County · Closure of the specific 2023 proposed local variance proceeding in Loudoun County; not closure of a facility or all local environmental concerns.
Virginia DEQ recorded withdrawal of its proposed local data-center variance on April 12, 2023, following public comment, and closed that proposal’s comment process.
Air & emissionsEnergy & affordabilityCommunity engagement
Status evidence: Apr 12, 2023Reviewed: Sep 27, 2026
Evidence context & limitations
Basis. An official state notice expressly says the proposal was withdrawn and the agency was not moving forward with that proposed variance.
Interpretation. The dated status evidence is missing or more than 365 days old. A new review date alone cannot refresh it.
Limits. Closure applies only to this historical proposal, not a current facility air-quality rating, an emissions measurement, or a finding that all generator concerns were resolved.
Chandler · Citywide data-center zoning-policy discussion in memorandum PLH22-0053; not an identified facility violation.
Chandler’s council memorandum describes potential neighborhood noise conflicts and proposes baseline sound studies, attenuation, acoustic testing and public-notification provisions for data centers.
NoiseCommunity engagement
Status evidence: Dec 8, 2022Reviewed: Sep 27, 2026
Evidence context & limitations
Basis. A dated municipal staff memorandum explicitly addresses noise compatibility and proposed safeguards.
Interpretation. The dated status evidence is missing or more than 365 days old. A new review date alone cannot refresh it.
Limits. This source is an agenda memorandum and proposed motion. It does not by itself confirm final ordinance adoption, the present municipal code, measured noise exceedances or resolution of a named complaint. The evidence is historical.
Wisconsin DNR documents Lighthouse campus environmental and permit review
Port Washington, Ozaukee County · The Lighthouse campus permit and environmental-review record in Port Washington.
Wisconsin DNR documents a June 12, 2026 air-permit decision following public comments, alongside environmental review covering wetlands, stormwater and municipal-service extensions for Vantage’s Lighthouse campus.

Status evidence: Jun 12, 2026Reviewed: Sep 27, 2026
Evidence context & limitations
Basis. The agency provides dated permitting and public-comment context, but the cited page does not establish a formal adverse finding or a verified resolution of community concerns.
Interpretation. The reviewed evidence does not support an action-state classification.
Limits. Permit issuance is not an exposure measurement, proof of absence of environmental impacts, a compliance certification or a violation finding. The page has no publication date; the status date is the explicit dated permit and supplemental-report milestone.
SELC reports a community-backed injunction request over Southaven turbines
Southaven · Power-generation infrastructure in Southaven serving greater Memphis data-center operations; not a Memphis, Tennessee data-hall location.

Status evidence: May 6, 2026Reviewed: Sep 27, 2026
Evidence context & limitations
Basis. The organization representing the plaintiffs reported a dated court filing. This is an attributed community/legal concern, not an agency finding or a judicial decision.
Interpretation. A source documents a concern, proposal, or review. An allegation is not a confirmed impact.
Limits. The publisher represents litigants and is a primary source for their position, not an independent adjudicator. No later court outcome, current turbine status, individual health causation or proven injury was verified for this record.
