The record, newest first

  1. An IDEM inspector finds four of the seven permitted generators installed and observes no violations; the other three may come with a later expansion phase. (Indiana Department of Environmental Management, Sept. 16, 2024)

  2. The plant begins operating, according to IDEM. (Indiana Department of Environmental Management, Sept. 16, 2024)

  3. The Portage council finalizes two property tax abatements for the $87 million project; an earlier vote had fallen short with one member opposed and three absent. (Lakeshore Public Media, Dec. 7, 2023; Inside INdiana Business, Dec. 20, 2023)

  4. IDEM issues the air permit, No. 127-47118-00169, covering seven emergency generators. (Indiana Department of Environmental Management, Sept. 16, 2024)

Conflicts and open questions

  • The Dec. 5, 2023 date comes from a Dec. 7 report of a vote at the council's Tuesday meeting. The final tally was not reported.
  • No record of a second building was found; the permit leaves room for added generators in a later phase.
