CHLOROBUTANE, 1- cleanup levels by state
- CAS 109-69-3
- 2 states
CAS 109-69-3 is in the cleanup-level tables of 2 states in this handbook: Florida (Chlorobutane, 1-) and Pennsylvania (CHLOROBUTANE, 1-). 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.

Each agency's own publication governs: its current table, or the published rule where the agency says so. This page is a reference copy and not a cleanup decision. Check each agency's page before relying on a value.
