None were in effect when we last checked. That is a calm day.

A gage is a measuring stick in the river. “Cubic feet per second” is how much water is moving. “Feet” is how deep it is at that stick.

EPA-regulated facilities 5,457 places
What is this?
Sites EPA tracks for air, water, or hazardous waste rules. A count is not a violation score.
Big climate-pollution reporters 38 places
What is this?
Factories, power plants, and landfills large enough that EPA makes them report greenhouse gases each year. Not every shop or farm — only the big ones. Latest complete year is 2023.
Places that report chemical releases (still open) 256 places
What is this?
Workplaces that use certain chemicals and file a yearly Toxics Release Inventory form. A count is not the same as “this county is dirty.” It means those sites exist and have not been marked closed.
