Ethanol cleanup levels by state

CAS 64-17-5
2 states

CAS 64-17-5 is in the cleanup-level tables of 2 states in this handbook: Florida (Ethanol) and Texas (Ethanol). Each state's numbers are below as its agency prints them. The states run different programs and do not define their values the same way, so a number from one is not the same measure as a number from another. A state that lists the substance under another CAS number, or without one, is not shown here.
