What is the minimum quantity of a hazardous substance that must be reported if released?

The minimum quantity of a hazardous substance that must be reported if released is referred to as the Reportable Quantity (RQ). This term is important in the context of environmental regulation and public safety. RQs are established by the Environmental Protection Agency (EPA) and are linked to specific substances that are considered hazardous under various laws, such as the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

If a hazardous substance is released into the environment in amounts that exceed the RQ, the responsible party is required to inform the appropriate authorities, typically local emergency responders and regulatory agencies. This reporting requirement is crucial because it ensures that necessary actions can be taken to mitigate any potential harm to public health and the environment.

Understanding the concept of RQ helps logistics professionals ensure compliance with environmental regulations and manage risks associated with the transportation and handling of hazardous materials. This knowledge is essential for maintaining safety procedures and protocols within logistics and supply chain operations.
