The story · Project BOSC

A data center is coming to Lima

A ~340-acre hardened data-center campus is being built in American Township, just outside Lima, Ohio — by a Delaware shell, “Bistrozzi LLC,” for an end user the developers worked to keep quiet. This story shows what the public record reveals, and teaches you how to read it yourself.

Every figure here is checkable.

Each number is read from a cited source and carries a confidence tag, so you never have to take our word for it:

[verified] read from a cited record [inference] a labelled reading of the record [open] withheld or unresolved

The whole story turns on small numbers

The Ottawa — the river this project discharges into, on a basin its cooling draws down — has a design low flow of about 0.2 cubic feet per second, and runs dry in the driest summers. Against that, a campus whose backup power and cooling are built for a city. Holding the document-by-document record against numbers like this is how the analysis moves from anecdote to evidence.

The story draws on 1,674 primary documents, 71 structured records, 100 resolved entities, and 182 dated events — the same feeds the reference library reads.

The story — six chapters

  1. 1 Who is actually building this? Reading a deed · cross-document entity resolution Anchor: The deed chain + the Bistrozzi Delaware shell cluster
  2. 2 How it was assembled & hidden Reading an options-to-assignment chain · the confidentiality-first sequence Anchor: The Port Authority options → Bistrozzi assignment + the blank DTE-100 prices
  3. 3 How big is it — and what won't they tell you? Reading an air permit · recognizing a CBI redaction Anchor: Ohio EPA Air Permit-to-Install P0138965
  4. 4 What it does to the water Reading an NPDES permit · the 7Q10 low-flow screen Anchor: NPDES dilution + the cooling-draw screen
  5. 5 What it costs the public Reading a cost estimate · reading a contract clause Anchor: Tetra Tech OPC + the Roadwork Development Agreement
  6. 6 Why you had to dig for this Reading statutory exemptions Anchor: The withholding stack + the mandamus thread

How the record is read

Each record is read from the image, not the OCR text layer (whose digits are unreliable), validated against a typed schema, and cited back to a source page — confidence surfaced inline as evidence tags. Read the full write-up: Methodology · the research course · or about the method.

provenance-first

Pre-launch. Assembled from public records the developer didn’t write. Registered-agent and organizer overlaps are common-control plumbing, not a verdict on ownership; inference is labeled [inference] and never dressed as fact. Nothing here is legal advice or a verdict — verify every figure against its cited source.
