Public Evidence combines facility identity, permits, source documents, emissions and power-system records without pretending that any one dataset is a complete U.S. data-center registry.
SOURCE REGISTER
The “use” and “limit” fields are part of the dataset. A blank federal match or missing bulk export remains visible rather than being filled by assumption.
U.S. Environmental Protection Agency
Connect FRS, ECHO, ICIS-Air, NEI, GHGRP and TRI records through stable program identifiers.
Boundary: Does not identify every data center and cannot support name-only facility matching.U.S. Environmental Protection Agency
Supply REGISTRY_ID, program-system identifiers, address, county and coordinates.
Boundary: One physical campus may have multiple names, addresses or program records.U.S. Environmental Protection Agency
Add ICIS-Air, enforcement, inspection and combined stationary-source emissions data.
Boundary: Federal reporting thresholds and program scope create real coverage gaps.New York State Department of Environmental Conservation
Supply Permit ID, facility, dates, georeference and direct permit-text URL.
Boundary: The dataset covers all State Facility air permits, not a classified data-center subset.Pennsylvania Department of Environmental Protection
Resolve facility and permit geography, then connect to permit tracking and air reports.
Boundary: Documents and facility records are split across multiple DEP interfaces.Texas Commission on Environmental Quality
Detect current data-center applications and retain permit numbers, received dates and application documents.
Boundary: Historical authorization and facility identity require Central Registry and Records Online joins.Ohio Environmental Protection Agency
Retrieve permits by entity, county, program, Facility ID and Permit ID.
Boundary: No stable bulk export was confirmed.Kentucky Energy and Environment Cabinet
Search Agency Interest numbers, issued approvals, pending approvals and applications.
Boundary: No stable public API was confirmed.U.S. Energy Information Administration
Add generator status, capacity, energy source and selected environmental equipment for plants at or above reporting scope.
Boundary: It is not an inventory of all standby engines or all data centers.U.S. Energy Information Administration
Add generation and fuel consumption for covered plants.
Boundary: Reported power-plant operation must not be generalized to total facility electricity use.U.S. Environmental Protection Agency
Connect covered stationary-source emissions to facility identities and reporting years.
Boundary: NEI scope, thresholds and estimation methods do not describe every generator or real-time emission.Federal Energy Regulatory Commission
Locate docketed filings and orders involving large loads, transmission projects and co-location questions.
Boundary: A filing may be a proposal, party position or procedural document rather than a Commission decision.U.S. Securities and Exchange Commission
Cross-check named operators, subsidiaries, capital commitments, risks and dated public-company disclosures.
Boundary: Company disclosures are not permits and may aggregate projects or omit site-level detail.Fairfax County, Virginia
Resolve local project records and connect applications to parcels, review steps and related permits.
Boundary: Workflow fields must be checked on the live record and do not prove construction or operation.Loudoun County, Virginia
Connect mapped data-center locations to local zoning, land-development and permit context.
Boundary: Map inclusion and local approval stages do not establish current operation or environmental performance.Prince William County, Virginia
Trace local development applications, permits and review activity for named projects.
Boundary: Search results require project-identity reconciliation and do not alone establish operating status.Virginia Department of Environmental Quality
Add water-withdrawal, wetlands and stream-review evidence to project profiles.
Boundary: Notice and permit scope must remain distinct from actual withdrawals or measured impacts.Pennsylvania Department of Revenue
Track the official eligibility and certification layer for data-center equipment incentives.
Boundary: Program eligibility or certification is not a project permit, operating record or net-benefit finding.Compute Atlas
Generate facility candidates and locate government-hosted sources for verification.
Boundary: Discovery metadata is not controlling evidence for project status, capacity, ownership or environmental performance.National Renewable Energy Laboratory
Cross-check broad spatial relationships among data centers, transmission, fiber and metropolitan areas.
Boundary: A map is not a row-level permit or operating-status registry.
