note
[verified] On 2025-12-03 the Allen County Sanitary Engineer, Brad Niemeyer PE, wrote to Jeremey Eisele PE of EMH&T formally authorizing the American-Bath POTW to receive "industrial or other non-domestic wastewater" from the Project BOSC data center. The authorization is contingent, and it requires the applicant to hold a valid OEPA Indirect Discharge Permit before any regulated wastewater is discharged. [verified] The applicant's own Wastewater Flow Schematic for that discharge is a single junction: non-contact cooling tower blowdown and sanitary flow both enter one lift station, and the lift station discharges to the sanitary sewer. No treatment, metering, equalization or separation of the two streams is shown anywhere on the drawing. [verified] The site plan shows the sanitary connection built in two stages — a TEMPORARY LIFT STATION with temporary gravity and force mains, all three annotated "REMOVE AFTER LIFT STATION (BY OTHERS) IS OPERATIONAL", alongside a "FUTURE LIFT STATION (BY OTHERS)". [open] Because the schematic commingles blowdown with sanitary flow upstream of the only measurement point the system has, no monitoring at American-Bath can separate the campus's cooling stream from its domestic stream. That is the structural reason the cycles-of- concentration work has only a back-solve and the discharge characterisation had to borrow a different site's data — but whether any instrument measures the blowdown separately is not settled by these three documents.
⚠ Gaps in the record
- The authorization is the POTW's, not Ohio EPA's, and it says so: it is "provided in fulfillment of the requirements for a new permit application" and is expressly "contingent upon the applicant's compliance with all applicable federal, state, and local statutes". It does not grant, and does not predict, the Indirect Discharge Permit — the letter itself requires a valid IDP "prior to the initial discharge".
- The flow schematic is an application exhibit, not an engineering drawing. It carries three labels and one box. Read it as the applicant's own statement of the flow path, not as evidence about equipment that is or is not installed.
- The site plan's pipe sizes and structure numbers are transcribed from the drawing's text layer, which on a CAD export carries the labels without carrying which line each belongs to. The sizes present in the drawing are recorded as a SET below; no size is attributed to a named run, because that attribution cannot be made from this read.
