US environmental regulators fixed a typo in fuel rules, nothing else changed
What happened
The US environmental regulators corrected a typo in a recent rule about fuel quality. This document does not change any of the actual requirements for fuel sampling or testing.
Why it matters
This document is a technical correction. It fixes a mistake in the legal text of a previous rule. It does not change how fuel quality is regulated or what companies must do.
The signal
There is nothing to watch here; this is a clerical fix.
