¹ Hazardous waste number.
² Chemical abstracts service number.
³ Quantitation limit is greater than the calculated regulatory level. The quantitation limit therefore becomes the regulatory level.
⁴ If o-, m-, and p-Cresol concentrations cannot be differentiated, the total cresol (D026) concentration is used. The regulatory level of total cresol is 200 mg/l.

Learn more about hazardous waste and the regulations that govern it:

• Definition of Solid Waste (DSW): Before a material can be classified as a hazardous waste, it must first be a solid waste as defined under RCRA. Resources, including an interactive tool, are available to help.

• Types of Hazardous Waste: Hazardous waste are divided into listed wastes, characteristic wastes, universal wastes, and mixed wastes. Specific procedures determine how waste is identified, classified, listed, and delisted.

• Generators: Hazardous waste generators are divided into categories based on the amount of waste they produce each month. Different regulations apply to each generator category.

• Transporters: Hazardous waste transporters move waste from one site to another by highway, rail, water, or air. Federal and, in some cases, State regulations govern hazardous waste transportation, including theManifest System

• Treatment, Storage, and Disposal (TSD): Requirements for TSD facilities govern the treatment, storage and disposal of hazadous waste, including land disposal, the permitting process and requirements for TSD facilities.

• Waste Minimization: EPA, States, and industries are working to reduce the amount, toxicity, and persistence of wastes that are generated.

• Hazardous Waste Recycling: EPA is addressing safe and protective reuse and reclamation of hazardous materials.

• Corrective Action: RCRA compels those responsible for releasing hazardous pollutants into the soil, water, or air to clean up those releases.

• Test Methods: EPA has a variety of analytical chemistry and characteristic testing methodologies, environmental sampling and monitoring, and quality assurance in place to support RCRA.

• International Waste: EPA provides information and guidance on regulations, agreements, initiatives, and other developments in waste policy and law, both in the United States and abroad.
