DEFINING HAZARDOUS WASTE

A waste is a hazardous waste if it is a listed waste, characteristic waste, used oil and mixed wastes. Specific procedures determine how waste is identified, classified, listed, and delisted.

TYPES OF HAZARDOUS WASTE

Hazardous waste is divided into different types (e.g., universal waste) or categories, including RCRA hazardous waste and non-RCRA hazardous waste. Properly categorizing a hazardous waste is necessary for land disposal restrictions, treatment standards and fees, amongst other things.

GENERATORS

Hazardous waste generators are divided into two categories (Small Quantity Generators and Large quantity Generators) 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 State regulations govern hazardous waste transportation, including the Manifest System. 

FACILITIES (TSDFs)

Requirements for TSD facilities govern the treatment, storage and disposal of hazardous waste, including land disposal, the permitting process and requirements for TSD facilities. 

HAZARDOUS WASTE RECYCLING

DTSC implements hazardous waste recycling laws and developed the hazardous waste recycling regulations to promote the reuse and reclamation of useful materials in a manner that is safe and protective of human health and the environment. Hazardous waste laws define recycling differently.
