Class 1 Wastes:
- Regulated asbestos-containing material;
- Materials containing specific toxic chemical constituents that exceed regulated concentration
levels, although not enough to be considered hazardous;
- Liquids that are ignitable at levels above 150 degrees F, or solids and semisolids that contain
chemicals considered to be ignitable under certain conditions incidental to storage, disposal, or treatment;
- Semisolids and solids that, when combined with water, exhibit corrosive properties;
- Empty containers that held hazardous substances or Class 1 wastes, unless the residue has been
completely removed through certain processes, such as multiple rinsing;
- Wastes containing more than 50 parts per million of total polychlorinated biphenyls (PCBs);
- Petroleum wastes associated with exploration, development, and production of crude oil, natural
gas, or geothermal energy and containing more than 1,500 parts per million total petroleum hydrocarbon (TPH);
- All nonhazardous industrial solid waste generated
outside Texas and transported into or through Texas for storage, processing, or disposal.
Class 2 Wastes:
- Containers that held hazardous or Class 1 industrial wastes where the residue has been completely removed
and the container has been made unusable;
- Containers, of less than 5-gallon capacity, that held Class 1 wastes;
- Depleted aerosol cans;
- Nonsurgical nonradioactive medical waste, not including breast implants, orthopedic devices, and other
"artificial, nonhuman devices removed from a patient and requested by the patient"11;
- Paper, cardboard, linings, wrappings, paper packaging materials, or absorbents that do not meet hazardous,
radioactive, or industrial Class 1 criteria;
- Food wastes, glass, aluminum foil, plastics, Styrofoam, and food packaging that result from plant production,
manufacturing, or laboratory operations.
Class 3 Wastes:
- Wastes not meeting the conditions of Class 1 or 2, including chemically inert and insoluble substances, samples
without detectable levels of PCBs or hydrocarbons, and wastes that pose no threat to human health or the environment;
- Inert, insoluble solid waste materials such as rock, brick, glass, dirt, and some rubbers and plastics.
