It's not true that Federal law requires emissions testing, but emissions testing programs, administered at the state level, are often in response to Federal air quality attainment requirements (or steps to show how you are working towards attainment in your non-attainment counties).
Yup, this, exactly. My county is the most populous in the state and had too many "bad air days" in the 1990s so we got emissions checks.
Sadly, most of our bad air comes from elsewhere in the country in the jet stream. So we have to suffer fixing our cars while someone in, say, Ohio, gets to burn coal for cheap electricity and also go without smogging their cars.
We could probably shake off the EPA, but we'd have to pay millions of dollars for the studies to prove it's no big deal anymore. We have an austere government that won't spring for it and I'm sure the mechanic lobby likes having to chase EVAP leaks.
