EPA is considering updating the flash point test methods for the determination of characteristically ignitable hazardous waste along with other minor changes. The currently required test methods refer to outdated standards developed by the American Society for Testing and Materials (ASTM standards) and require instrumentation that is no longer readily commercially available. In addition, the standards require the use of mercury thermometers. A proposed update to the flash point test methods will allow for the use of commercially available instrumentation and will no longer require mercury thermometers. EPA is also considering removing the requirements for mercury thermometers from the SW-846 Compendium sampling methods. In addition, EPA may take comment on the alcohol exclusion for ignitable aqueous alcohols and whether a revision is necessary to improve existing waste management practices.
