What is the regulatory level for total cresol under the Toxicity Characteristic rule?

The regulatory level for total cresol under the Toxicity Characteristic rule is set at 200 mg/l. This value is important because it establishes a threshold concentration for determining whether waste exhibits the toxicity characteristic, which is fundamental in identifying whether a waste is considered hazardous. If the concentration of total cresols in a waste sample exceeds 200 mg/l, the waste is deemed hazardous and subject to stricter regulatory controls.

Understanding this level is crucial for waste handlers and generators, as it influences waste management practices, compliance with Environmental Protection Agency (EPA) regulations, and subsequent environmental protection strategies. The Toxicity Characteristic is one of the key components of the Resource Conservation and Recovery Act (RCRA), which aims to manage hazardous waste more safely and effectively.
