Asbestos which is contained in buildings which are to be demolished is not waste while the buildings are standing and is not hazardous unless it is friable. Demolition serves to make the asbestos both waste and hazardous and thus subject to fees. 8/25/89.
Classification of Substance as Hazardous Waste
The Department of Toxic Substances Control has the sole authority to decide whether or not a substance is a hazardous waste. 1/24/92.
Containers and Packing Materials
Any containers or packing materials which come into direct contact with hazardous waste and which are treated or disposed of with the hazardous waste are also regarded as hazardous waste. 11/5/93.
Materials Previously Classified by DTSC as Non-Hazardous
The Board does not have the authority to reverse a conclusion of the Department of Toxic Substances Control (DTSC) with respect to the toxicity of a material. However, if DTSC has concluded that a particular material is not hazardous, the Board will consider the material to be non-hazardous in subsequent cases. 12/31/91.
If a waste material is hazardous, any mixture containing the material is regarded as hazardous. It is immaterial that the workplace in which the hazardous waste is generated meets worker safety standards. 1/6/93.
