The U.S. Environmental Protection Agency (EPA) issued a proposal in the Federal Register (84 Fed. Reg. 12539) to “modernize” the determination for the characteristic of ignitability for liquids under the Resource Conservation and Recovery Act (RCRA). Comments are being accepted until June 3, 2019, and the final rule is projected to be issued in early 2020.
Under current RCRA regulations, solid wastes are classified and regulated as hazardous wastes if they are explicitly listed as such. They can also exhibit a “characteristic” property of hazardous waste: ignitability, corrosivity, reactivity or toxicity.
The ignitability characteristic specifies that the following qualify as hazardous wastes:
According to the EPA, states will not have to adopt the rule as it is “neither more nor less stringent” than the current one. However, certain aspects could cause significantly more wastes to be classified and regulated as hazardous wastes under RCRA.
A few states do have ignitability characteristics that vary from the federal rule. It is likely that some states will need to adopt the new requirements into their regulations.
Specifically, the proposed rule may have a significant impact on mining companies, wastewater treatment systems, laboratories and any generators that manage chemicals used for solvent properties.
