The discharge & the receiving water
Dilution at the design low flows, and the burden the receiving water already carries.
- baseline context only — the project-side record has not been produced
A real impact study screens the project's discharge against the assimilative capacity of the receiving stream — how much pollutant that stream can take before it breaches a criterion — at the stream's cited design low flows. The design flow matches the criterion type: chronic aquatic-life dilution at the 7Q10, and acute dilution at the 1Q10, which is the sharper single-day design low flow. It also sets that discharge beside what the county's TRI reporters already release. These are screening bands. They are not a permit determination.
No project discharge has been characterized for this site — the screen renders the day an NPDES application and its fact sheet are filed. What follows is the receiving water's own baseline.
What the county's TRI reporters already release
| Facility | City | RSEI score |
|---|---|---|
| VALBRUNA SLATER STAINLESS INC | FORT WAYNE | 10,250,595.6 |
| KS KOLBENSCHMIDT US, INC. | FORT WAYNE | 3,983,694.7 |
| DEKKO STAMPING | FORT WAYNE | 2,636,260.5 |

| BRUNSWICK LEISURE BOAT CO | FORT WAYNE | 1,524,881.5 |
Any new discharge lands on top of this baseline — the point of reading the two halves together. The full ranked inventory and its reading caveats are in the RSEI annex.
- Only the receiving water's existing burden is on the record here — the project-side discharge screen renders the day a characterization is filed.
The record behind this chapter
What this chapter stands on: the records it reads, the inputs its modeled figures rest
on, and the reference data behind its baselines — the same pages the record screens
serve, not a second copy. A figure the record does not support stays [open] and links nothing.
