Notice of Intent for coverage under Construction Site Stormwater General Permit OHC000006, electronically submitted 2025-12-01. Applicant Amazon Data Services, Inc., 410 Terry Ave N, Seattle WA; applicant contact Robert Truedinger; facility contact Seth Bell. Coordinates 40.26920527 / -84.19566214. Receiving stream field reads verbatim 'Mill Creek, Mill Branch'. Total land disturbance 230.7 acres; project 2025-10-31 to 2027-05-31. Declares Isolated Wetland 'YET_TO_APPLY', Individual NPDES 'NO', individual 401 WQC 'NO', USACE nationwide permit 'NO'. The stormwater outlet is Mill Creek, NOT the Great Miami mainstem the campus's sanitary wastewater reaches via the Sidney WWTP (1PD00009/OH0027421) — two different denominators for two different flows.
⚠ Gaps in the record
- Receiving stream is printed on the NOI as 'Mill Creek, Mill Branch' — two named waters in one field. Recorded here as 'Mill Creek' so the entity graph resolves one water per node; the verbatim field value is preserved in `note`.
- The NOI declares Ohio EPA PTI status 'YET_TO_APPLY' — the sanitary-sewer PTI (DSWPTI-260517) did not issue until 2026-06-16, six months later.
- The NOI carries the FULL facility permit number 1GC10596*AG in its 'Existing NPDES Facility Permit Number' field even though it is the application, submitted 2025-12-01, four days before the 2025-12-05 approval letter that grants the coverage. Recorded as printed. Entity-graph facility identity keys on the base number either way (`_base_permit` strips the *AG action suffix), so this and the approval and co-permittee records resolve to one facility node.
