Who actually pays for a nutrient upgrade at a small plant

What is driving spend

We read 5,677 Clean Water SRF project entries across 39 states and matched them to live NPDES permits for design flow. In practice these intended use plans and priority lists name the applicant, the project and the amount, and most carry some indication of readiness. That makes them the closest thing there is to a public schedule of who is about to build.

Overlaying that with EPA's quarterly non-compliance record gives the set that actually matters: 81 plants that are lagoon-based, inside 5 MGD, queued for funding, and carrying reported effluent limit violations in the last three years.

The technical question is rarely the one that decides this. The decision turns on what is fundable, what the deadline really is, and what the ratepayer consequence looks like over twenty years.

How the money actually works

Your position on the state Clean Water SRF priority list is public, as is the amount and the readiness stage. Three things follow from that which are easy to miss:

Check the vintage. Sixteen states publish current 2025-26 documents. The rest are only available as 2022-23 copies. If someone quotes your priority list position, ask which year's list they are reading.
