Define a Large Quantity Generator (LQG).

A Large Quantity Generator (LQG) is defined as a waste generator that produces more than 1,000 kilograms of hazardous waste per month. This classification is crucial for regulatory purposes, as LQGs are subject to stringent regulations under the Resource Conservation and Recovery Act (RCRA) due to the volume and potential risks associated with their hazardous waste generation.

The significance of this classification lies in the compliance requirements and the responsibilities that LQGs have in managing their hazardous waste, which include obtaining permits, keeping detailed records, and adhering to specific treatment, storage, and disposal regulations. Additionally, being categorized as an LQG often impacts how state and federal regulatory authorities oversee the generation, management, and disposal processes.

The other options represent different classifications of waste generators. For instance, those generating less than 100 kilograms per month qualify as Conditionally Exempt Small Quantity Generators, while those producing between 100 and 1,000 kilograms monthly fall into the Small Quantity Generator category. These classifications come with different regulatory requirements, which makes the distinction between them essential for environmental compliance and safety management.
