Permit and comment: AWS Wheatfield Campus (Project Rise)

Indiana Department of Environmental Management published a draft air-permit notice for Amazon Data Services in Wheatfield. Its later notices schedule a November 10, 2026 hearing following a hearing request and comments, and extend comments through November 16. This documents a pending permit procedure, not an issued permit, completed hearing or finding of measured impacts.

Record status: pending. Indiana Department of Environmental Management published an extended comment period and scheduled a hearing for the named draft air permit. Pending applies only to that process. Comments are extended through November 16, 2026, with a hearing scheduled for November 10. No final decision, completed hearing, current operation or resolution of every concern was verified.

Event date: September 24, 2026

The original extension notice expressly identifies September 24, 2026 as the initial notice posting. November 10 is a scheduled future hearing, not an event already held. The initial notice was published September 24, 2026, as confirmed by the original extension and current agency row. Exact first posting days for the hearing and extension documents remain unknown; filenames are not publication dates.

News report: St. Joseph County

WVPE reported South Bend council questions about the composition of wastewater from an Amazon data center sent to the city's treatment plant. This records an outlet account of public questions. It does not establish the exact originating campus, contaminant levels, a discharge violation or a current permit outcome.

Record status: unknown. The disposition of the reported water-composition questions is unknown in this bounded review. A proposed transparency bill and historical interview account do not establish a current water-quality result, permit decision, wrongdoing or resolution.

Event date: Not established

Source publication date: September 8, 2026

Disposition date: Not established

Concern sources checked: October 18, 2026

The outlet refers to an August 20 committee meeting and reported later conversations. The exact independently reviewed concern-event day remains unknown because original minutes and a filed utility inquiry were not inspected. The original report displays September 8, 2026 publication. That day is outlet publication, not an independently established discharge event, contamination finding or agency order.

News report: Microsoft Granger Data Center

WVPE reported dust, construction-truck and backup-generator questions about Microsoft's Granger project, following earlier reporting on electricity rates and reliability. It described county officials' monitoring and dust-control accounts. These are attributed reports and plans, not independently measured conditions, a published formal complaint case or a resolved compliance finding.

Record status: unknown. The later outcome of the documented concerns is unknown in this bounded review. County monitoring accounts and company plans do not establish measured air conditions, completed mitigation, the outcome of individual complaints or current compliance.

The reports describe several panel and county meetings. A single independently checked exact concern-event day is not established for this combined report item. The company separately identifies a May 19, 2026 open house, not a formal agency hearing. The later original WVPE report was published May 30, 2026; background reporting was published February 19. The company recap was first published May 20, separate from its May 19 meeting. The exact first publication day of the linked company PDF remains unknown.

Company-published statement

Microsoft stated in its community materials that it plans to cover infrastructure costs, coordinate water supply and obtain applicable generator permits. The materials describe planned cooling and design measures. These are company commitments and plans, not independently verified permits, achieved mitigation or measured resource use.

The original company recap links these materials from its May 19, 2026 St. Joseph County meeting, and their site context matches Granger. They precede the May 30 construction report and are not an express answer to its dust or truck-route accounts. The exact first PDF posting date is unknown.

Permit and comment: St. Joseph County

Indiana Department of Environmental Management recorded public questions about generator air, health, water, electricity and traffic in its New Carlisle air-permit review for Amazon at 55001 Larrison Boulevard. The agency documented two meetings and its responses. This is a permit/comment record; the reviewed cover has no completed issue date and does not verify a final present-day outcome.

Record status: unknown. The present formal permit disposition and outcome of the documented concerns are unknown in this bounded review. The packet records completed meetings and agency responses, but its blank issue-date cells and statement that a permit will issue do not establish a signed final issuance, current compliance or resolution of every concern.

Event date: October 1, 2024

Source publication date: October 1, 2024

Disposition date: Not established

Concern sources checked: October 18, 2026

The agency addendum expressly confirms October 1, 2024 as the initial notice posting and records meetings held December 5, 2024 and January 9, 2025. It does not establish one exact filing day for every public comment. The original initial notice was posted October 1, 2024, as confirmed in the later agency addendum. The current addendum packet has no independently established first posting day, and a blank cover issue-date cell is not a publication or final decision date.
