On April 2, the Environmental Protection Agency (EPA) proposed to update their regulations for the identification of ignitable hazardous waste under the Resource Conservation and Recovery Act (RCRA) and to modernize the RCRA test methods that require the use of mercury thermometers.

Conditions of the proposal include:

  • Publishing new acceptable flash point test methods for determining if a liquid waste is an ignitable hazardous waste. The current methods, which will still be acceptable, were published 40 years ago. Newer technology that does not require mercury thermometers is now available. The new methods are ASTM Standard Test Methods.
  • Updating the Aqueous Alcohol Exclusion to clarify the exclusion’s scope by codifying the existing guidance into the regulatory text.
  • Seeking public input on other potential changes to the Aqueous Alcohol Exclusion.
  • Clarifying how to properly test multiphase wastes that contain multiple liquid(s) with or without solids for ignitability determinations.
  • Updating and replacing outdated references to the Bureau of Explosives to be consistent with current Department of Transportation (DOT) regulations. The Bureau of Explosives no longer has authority to dictate to the DOT the appropriate testing of aerosol ignitability (49 CFR 173.115).
