How are wastes listed under RCRA?

How are wastes listed under RCRA?

• A. Wastes are listed by weight thresholds.
• B. Wastes are listed as F-listed or K-listed, representing non-specific source wastes and source-specific wastes respectively.
• C. Wastes are not listed under RCRA.
• D. Wastes are listed only by color.

Answer: (B)

Under RCRA, wastes are identified through specific lists that categorize them by origin. F-listed wastes are non-specific source wastes, often including spent solvents from various processes. K-listed wastes are source-specific wastes tied to particular industries or processes. This distinction between generic and industry-specific sources is what the listing system uses, rather than listing wastes by weight or color. There are also other lists (such as P and U for certain commercial chemicals) and wastes can be hazardous by characteristic, but the described approach of F-listed and K-listed best matches how wastes are officially categorized under RCRA.
