Waste management, a critical component of modern life, often involves the handling of materials that pose significant risks to human health and the environment. Among these hazards, Extremely Hazardous Air Pollutants (EHAPs) are a particularly concerning category. These substances, designated by the US Environmental Protection Agency (EPA), have the potential to cause severe health effects even at extremely low concentrations.
Understanding EHAPs:
EHAPs are a subset of the larger group of hazardous air pollutants (HAPs) and are defined by their potential to:
The EPA has identified 188 substances as EHAPs, encompassing a broad range of chemicals, including:
EHAPs in Waste Management:
EHAPs can be found in various waste streams, including:
Risks Associated with EHAPs in Waste:
The improper handling and disposal of waste containing EHAPs can lead to:
Managing EHAPs in Waste:
Effective EHAP management in waste management requires a multi-pronged approach:
Moving Forward:
Addressing the challenges posed by EHAPs in waste management requires a collaborative effort between government agencies, industry, and communities. By implementing robust waste management systems, promoting responsible practices, and investing in research and development of new technologies, we can minimize the risks associated with these toxic substances and protect human health and the environment.

Instructions: You are the manager of a small manufacturing company that produces plastic products. Your company generates waste containing solvents, heavy metals, and other chemicals. Create a basic EHAP management plan outlining the steps you would take to minimize the risks associated with these substances.
Your plan should include:
This is a sample answer. There is no single "correct" answer, but your plan should demonstrate an understanding of EHAPs and the principles of safe waste management.
