Oregon | News Flash. They do.
It is called an NPDES permit and it is required for all point source storm water discharges within municipal areas subject to MS4 permitting requirements.
Ag has an exemption. Municipal stormwater does not.
The challenge in our area is keeping municipal storm water discharges out of irrigation conveyance facilities when the municipality is too small to be subject to its own MS4 permit.
