The refiners must buy more expensive crude

Essentially no crude oil exists in sulfur levels this low. 10 ppm is 0.001% (one one-thousandth of a single percent). For comparison:

The very best on this list, the Malaysia-Tapis (world's most expensive crude oil) is 0.0343% sulfur or 34 times more sulfur than the new allowed value.

Instead refineries must spend capital dollars to add hydrotreaters and the like to remove more sulfur during the refining process. Those units consume energy adding never ending greater expense even after the building of new units is done.
