Hazardous wastes include:

Hazardous wastes are defined as wastes that can pose substantial or potential threats to public health or the environment. They typically contain harmful substances and are subject to stringent regulations under laws such as the Resource Conservation and Recovery Act (RCRA).

The correct answer indicates that none of the options listed accurately represents hazardous wastes. Industrial discharges permitted under the Federal Water Pollution Control Act (FWPCA) typically refer to liquid waste being released into water bodies and are regulated under different criteria than hazardous waste. These discharges may be permitted, but they do not automatically classify as hazardous waste.

Agricultural wastes, although they can sometimes contain hazardous components, are generally managed through different regulations focused on agricultural practices and are not universally classified as hazardous waste.

Permitted irrigational waters involve managing water for agricultural use and are not classified as hazardous waste either. They are treated and regulated separately within the context of their impact on water quality and agricultural practices.

Thus, since none of the provided options falls under the definition or typical classification of hazardous wastes, the answer indicating that none of the above are considered hazardous waste is accurate.
