Definition

This is the generic class for (1) hazardous or toxic waste destruction by any means to include, heating, chemical action, or the interaction with any form of radiation; (2) permanent containment of hazardous or toxic waste by methods to include storage in a simple container, solidification, vitrification, cementation, and more elaborate methods of storage such as marine, tetonic, or extraterrestrial storage; (3) hazardous or toxic waste conversion by any means (e.g., chemical, physical, etc.) to an environmentally safe substance; and (4) preparation for destruction or containment as well as the actual destruction or containment.

(1) Note. Chemical substances that move through commerce and are used or treated in some useful application are not considered to be hazardous or toxic waste. These substances may be considered hazardous or toxic waste in the event they are introduced into the environment in a manner not consistent with their intended utility. (2) Note. Waste proper for classification in Class 588 is considered to be too hazardous or toxic for placement in an ordinary municipal landfill.

Lines with other classes and within this class

Line With Classes Producing Desired Useful Product

A process which produces a desired product for an end use, e.g., by manufacturing, chemical reaction, or purification etc., is classified with the product produced and controls over Class 588 regardless of whether or not a toxic or hazardous waste is destroyed or contained as part of the process. Class 588 provides for a process which destroys or contains hazardous or toxic waste and whose products are intended only to be safely discarded or whose production is only incidental to the destruction or containment.

Line With Method Classes

Class 588 controls over general method classes for storing or containing waste which is too hazardous or toxic to be placed in an ordinary municipal landfill.

Line With Apparatus Classes

This class does not provide for apparatus. Apparatus is classified based on its function without regard to whether or not hazardous or toxic waste is the substance acted on. Significant disclosure to processes of treating hazardous or toxic waste in apparatus patents may be cross-referenced to Class 588 as appropriate.

Line With Other Classes That Provide for Destroying Hazardous or Toxic Waste

Class 588 controls over general classes that are only incidental to the destruction or containment of hazardous or toxic waste.
