    meta-jeffersonville → Cooling + water

    Field Cooling + water

    From Company claim

    To Unknown

    Why The page tests a common inference about what the announcement establishes; Meta did not make the cooling-and-water statement shown.

    Evidence re-reading of the sources already cited on this claim; no new source.

  1. Correction · 14 September 2026 · Editorial classification update

    Record → Power / rates

    Field Power / rates

    From Not independently verified

    To Partially supported

    Why The tariff supports part of the risk-allocation claim, but it does not prove that generation, transmission or wholesale-market costs can never affect household bills.

    Evidence re-reading of the sources already cited on this claim; no new source.

  2. Correction · 14 September 2026 · Editorial classification update

    meta-lebanon → City impact payment

    Field City impact payment

    From Not independently verified

    To Supported

    Why The government announcement supports the stated term. It does not establish an executed agreement, a due date or any payment received.

    Evidence re-reading of the sources already cited on this claim; no new source.

  3. Correction · 14 September 2026 · Editorial classification update

    meta-lebanon → Permanent jobs

    Field Permanent jobs

    From Not independently verified

    To Company claim

    Why The figure is a company projection; neither cited announcement is an observed payroll or employment record.

    Evidence re-reading of the sources already cited on this claim; no new source.

  4. Correction · 14 September 2026 · Editorial classification update

    sabey-indianapolis → Power / cost allocation

    Field Power / cost allocation

    From Not independently verified

    To Partially supported

    Why The cited commitment supports cost allocation for one site, but it cannot establish the statewide generalization shown.

    Evidence re-reading of the sources already cited on this claim; no new source.

  5. Correction · 14 September 2026 · Editorial classification update

    aws-new-carlisle → State incentives

    Field State incentives

    From Not independently verified

    To Supported

    Why The government announcement, portal fields and agreement support the carefully limited description of authorized terms. They do not prove delivery, jobs or completed investment.

    Evidence re-reading of the sources already cited on this claim; no new source.

  6. Correction · 14 September 2026 · Editorial classification update

    aws-new-carlisle → Project status

    Field Project status

    From Not independently verified

    To Unknown

    Why This card tests a common inference, not an attributed outside statement. The operating milestone still does not establish completion of every planned building or the full campus.

    Evidence re-reading of the sources already cited on this claim; no new source.

  7. Correction · 14 September 2026 · Editorial classification update

    meta-lebanon → Investment

    Field Investment

    From Not independently verified

    Why The exact investment figure is a Meta projection. The government announcement repeats it but does not establish completed or placed-in-service capital.

    Evidence re-reading of the sources already cited on this claim; no new source.

  8. Correction · 14 September 2026 · Editorial classification update

    meta-lebanon → State sales-tax exemption

    Field State sales-tax exemption

    From Not independently verified

    To Supported

    Why The government announcement supports the stated term. It does not establish the controlling agreement or exemptions actually claimed.

    Evidence re-reading of the sources already cited on this claim; no new source.

  9. Correction · 14 September 2026 · Editorial classification update

    microsoft-la-porte → Jobs / timing

    Field Jobs / timing

    From Not independently verified

    To Contradicted

    Why The claim says the projected jobs already exist, while the cited company source still describes a forecast and the government source describes a different job scope.

    Evidence re-reading of the sources already cited on this claim; no new source.

  10. Correction · 14 September 2026 · Editorial classification update

    meta-lebanon → Construction jobs

    Field Construction jobs

    From Not independently verified

    To Company claim

    Why The peak construction-jobs figure is a company projection, not an observed workforce count or job-years measure.

    Evidence re-reading of the sources already cited on this claim; no new source.

  11. Correction · 14 September 2026 · Editorial classification update

    meta-lebanon → Water / cooling

    Field Water / cooling

    From Not independently verified

    To Unknown

    Why The prior label is defined for an unverified statement by a non-company party. This card tests a common inference instead; the reviewed company source does not establish annual or total campus water use.

    Evidence re-reading of the sources already cited on this claim; no new source.

12 September 20267 entries

  1. Correction · 12 September 2026 · Software-assisted second check

    aws-new-carlisle → Project status

    Field Project status

    Why The operating Project Rainier milestone does not establish completion of every planned New Carlisle building or the full campus.

    Evidence re-reading of the sources already cited on this claim; no new source.

  2. Correction · 12 September 2026 · Software-assisted second check

    Record → Taxes / incentives

    Field Taxes / incentives

    From Partially supported

    To Contradicted

    Why The reviewed statute remains in force, and the reported pause concerns new requests rather than repeal or cancellation of existing agreements.

    Evidence re-reading of the sources already cited on this claim; no new source.

  3. Correction · 12 September 2026 · Software-assisted second check

    Record → Taxes / incentives

    Field Taxes / incentives

    From Partially supported

    To Contradicted

    Why The statute authorizes a complete or partial equipment sales-and-use-tax exemption; it does not establish that a qualifying project pays no taxes.

    Evidence re-reading of the sources already cited on this claim; no new source.

  4. Correction · 12 September 2026 · Software-assisted second check

    meta-lebanon → Water / cooling

    Field Water / cooling

    From Partially supported; unknowns not recorded

    To Not independently verified; operating water unknowns and the future design scope are explicit

    Why The second review found that a literal zero-water conclusion is not established by Meta's narrower future design statement.

    Evidence re-reading of the sources already cited on this claim; no new source.

  5. Correction · 12 September 2026 · Software-assisted second check

    sabey-indianapolis → Power / cost allocation

    Field Power / cost allocation

    From Partially supported

    To Not independently verified

    Evidence re-reading of the sources already cited on this claim; no new source.

  6. Correction · 12 September 2026 · Software-assisted second check

    microsoft-la-porte → Jobs / timing

    Field Jobs / timing

    From Not yet due

    To Not independently verified

    Why The 600-plus first-phase forecast has no retrieved due date; the 2032 date belongs to a different 200-job scope.

    Evidence re-reading of the sources already cited on this claim; no new source.

  7. Correction · 12 September 2026 · Software-assisted second check

    Record → Power / rates

    Field Power / rates

    From Partially supported; framed as stranded distribution investment

    To Not independently verified; scope narrowed to AEP Ohio and infrastructure/transmission risk

    Why The second review found that the tariff supports risk allocation but not the absolute household-bill conclusion, and PUCO's own description is not limited to distribution.

    Evidence re-reading of the sources already cited on this claim; no new source.

    vantage-oh2-millersport → OPSB / generation status

    Field OPSB / generation status

    From The source link used an OPSB case-summary URL that now returns 404.

    To The working source link now opens Fairfield Energy's live project page, which identifies OPSB case 26-0160-EL-BGN.

    Why The historical OPSB summary is described as preserved evidence rather than presented as a working page; the official case-summary URL returns 404 and the Docketing Information System rejected a direct case request during this check.

    google-the-dalles → Cooling + water

    Field Cooling + water

    From Google The Dalles: Mixed evidence

    To Google says The Dalles aquifer project added more than 100 million gallons a year of stored-water capacity for the community.

    Why A source re-read replaced a generated status label with the exact company claim and separated community storage capacity from data-center water use.

    Evidence No additional evidence link; see the linked record or claim.

  2. Correction · 16 September 2026 · Editorial classification update

    meta-jeffersonville → Cooling + water

    Field Cooling + water

    From Meta Jeffersonville: Not verifiable

    To Meta's Jeffersonville announcement establishes the campus's cooling design and water use.

    Why A source re-read converted a generated status label into the exact inference being tested and restored a concise unit boundary.

  3. Correction · 16 September 2026 · Editorial classification update

    microsoft-mount-pleasant → Cooling + water

    Field Cooling + water

    From Microsoft Mount Pleasant: Announced

    To Microsoft says its Mount Pleasant pilot will use closed-loop chip-level cooling without evaporating water for cooling.

    Why A source re-read replaced a generated status label with the exact company claim and restored a concise unit boundary.

    Field Power / developer claim

    From Only company descriptions of the proposed adjacent power facility were cited.

    To The preserved official OPSB case summary is cited separately from the developer's differing generation and storage figures.

    Why Primary-record follow-up confirmed the proposal and hearing date while preserving the unresolved MW discrepancy and outcome hold.

    Record → Water / permits

    Field Water / permits

    From The direct Ohio EPA decision notice had not been retrieved.

    To The preserved official Ohio EPA Community Notice is cited with its dated heading and exact page location.

    Why Primary-record follow-up recovered the agency's own notice, and the second review re-read it; a later live recheck was unavailable and is not treated as a retraction.

    From The evidence link opened the report landing page and described the unit as million US gallons.

    To The evidence link opens the report PDF, cites the exact p. 97 table, and uses its printed unit, million gallons.

    Why Independent re-extraction confirmed the three Google-reported Ohio rows without turning company reporting into municipal measurement.

  4. Correction · 12 September 2026 · Software-assisted second check

    aws-new-carlisle → State incentives

    Field State incentives

    From The contract split was held because no independent retrieval was recorded.

    To Five Project 424567 portal instruments and the DATA agreement are cited with exact fields and contract locators.

    Why The second review reproduced the portal records while preserving the difference between authorized terms, portal fields, and observed outcomes.

  6. Correction · 12 September 2026 · Software-assisted second check

    microsoft-quincy → Cooling + water

    Field Cooling + water

    From Microsoft Quincy: Supported as delivered; combined measures and a 2021-2022 observation window

    To EPA documents an operating reuse system; distinct estimates and dated observations are separated

    Why The second review separated estimated savings, canal makeup and potable makeup share and removed an unsupported original-publication year.

    Evidence No additional evidence link; see the linked record or claim.

  7. Correction · 12 September 2026 · Software-assisted second check

    vantage-oh1-new-albany → Opening status

    Field Opening status

    From The tested opening proposition was attributed directly to Vantage Data Centers.

    To The proposition is labeled as a common reading; Vantage is cited only for its December 2025 opening target.

    Why The operator page states a forecast and does not claim that the first building opened or is operating.

  8. Correction · 12 September 2026 · DataCenterData review

    edgeconnex-new-albany-oh → Lifecycle status

    Field Lifecycle status

    To Corrected operating to construction. The prior basis itself said operation was not established; city records support an active building project and groundbreaking, not operation.

    Evidence No additional evidence link; see the linked record or claim.

  9. Correction · 12 September 2026 · Software-assisted second check

    Record → Taxes / jobs

    Field Taxes / jobs

    From Statewide tax/jobs scope; underlying operator not specified

    To One unnamed New Albany hyperscaler, tax year 2024 payable 2025; city-reported comparison

    Why The second review narrowed the place, taxpayer and time scope and made the missing underlying records explicit.

    Evidence No additional evidence link; see the linked record or claim.

  10. Correction · 12 September 2026 · DataCenterData review

    sabey-indianapolis → Lifecycle status

  11. Correction · 12 September 2026 · Software-assisted second check

    Record → Statewide count

    Field Statewide count

    From The directory denominator can include buildings, suites and campuses; March 2026 PDF

    To The directory unit and deduplication are unreconciled; retained March-path PDF differs from the live page's current May-path target

    Why The second review removed an unsupported description of the directory denominator and distinguished URL-path timing from publication date.

    Evidence No additional evidence link; see the linked record or claim.

  12. Correction · 12 September 2026 · Software-assisted second check

    vantage-oh2-millersport → OPSB / generation status

    Field OPSB / generation status

    From The claim cited only Fairfield Energy's application description.

    To The claim now separates the preserved OPSB summary's 1,300/1,000 MW figures from Fairfield Energy's 1,350/1,040 MW figures.

    Why The official and company summaries disagree; neither is converted to data-center IT capacity and the underlying filing remains unavailable.

  1. Correction · 11 September 2026 · DataCenterData review

    Record → Power / rates

    Field Power / rates

    From The PUCO-approved AEP Ohio tariff allocates substantial underuse and cancellation risk to new loads over 25 MW. That is real protection against stranded distribution investment; it is not proof that generation, transmission or wholesale-market costs can never affect household bills.

    To Added how the 85% minimum-demand term works by contract size and AEP's count of pre-tariff contracted load. Verdict unchanged. The 72.5% and 82.5% shares are DataCenterData arithmetic from AEP's published formula (15,000 kW plus 85% above 25,000 kW up to 75,000 kW; 57,500 kW plus 100% above 75,000 kW; capped at 85% of contract capacity).

    aws-new-carlisle → Permanent jobs

    Field Permanent jobs

    From At least 1,000 baseline; AWS's own July 2026 account says nearly 1,000 operations staff hired; an undated Chamber project page says 1,056 full-time AWS employees

    To 2026-09-11: status was 'supported-as-delivered' with value 'At least 1,000 baseline; 1,056 full-time AWS employees later reported'. The company-linked counts sit on either side of the baseline (AWS op-ed: 'We have also hired nearly 1,000 operations staff so far'; Chamber page: '1,056 full-time AWS employees', undated), so the reviewed record does not support a delivery conclusion. Evidence level unchanged.

    Record → Water / permits

    Field Water / permits

    From Draft Ohio data-center general NPDES permit treated as if it were a final, measured water authorization.

    To Ohio EPA said on July 21, 2026 that it would not finalize draft OHD000001 and would continue with individual NPDES permits. A permit is not measured discharge.

    Why Correction chronology uses the recorded date, not the 21 July agency-event date.

    To Minutes record unanimous adoption of R-3-2026 under a title describing rescission of the 2024 taxpayer agreement and termination of its tax abatement; adopted resolution text not obtained; IEDC DATA exemption pending.

    Why Correction chronology uses the recorded date 2026-09-11; the source event date remains 2026-03-02.

    Field Record

    To previously '35-year state sales-tax exemption for at least $800M eligible capital, with extensions tied to additional eligible investment up to 50 years.' The $800M figure is the announcement's wording; the executed agreement (Exhibit A, section 2.A, page 13 of 18) says $845,000,000.

    Field Statewide count

    From Ohio's consumer advocate repeats a commercial directory count. It is useful as a market signal, but the underlying unit can include buildings, suites and campuses and is not a state census. DataCenterData does not adopt 200+ as its own count.

    To The 2 March 2026 council minutes record unanimous adoption of Resolution R-3-2026, whose agenda title describes rescission of the 2024 Microsoft taxpayer agreement, including termination of the tax abatement. DataCenterData has not obtained the adopted resolution text and therefore does not independently state its full legal effect.
