Yes when the EPA mandated lower sulphur diesel, the price went up, and availability went down. Expect the same when this mandate is applied to gasoline. The present 30 ppm is already low, so making it lower makes the effort to meet it very, very difficult. The refiners must buy more expensive crude and hit it hard during the process to meet the goal.

The EPA has an agenda, raise carbon fuel prices to the point the green energy can be said to be an alternative. Of course at that point we will be riding bicycles to work like in Denmark or Holland [countries the size of CT & Rhode Island].

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.
