How does the EPA categorize large quantity generators (LQGs)?

The correct categorization of large quantity generators (LQGs) is producers of 1,000 kg or more of hazardous waste per month. The Environmental Protection Agency (EPA) defines LQGs this way to establish a regulatory framework that ensures that those who generate significant amounts of hazardous waste are subject to stricter waste management standards. This threshold allows the EPA to focus oversight on facilities that, due to the volume of waste generated, pose a higher risk to human health and the environment if not managed properly.

By setting the limit at 1,000 kg, the EPA seeks to regulate and monitor the practices of these generators more closely, ensuring they follow all required protocols for hazardous waste handling, storage, and disposal. This helps mitigate potential contamination of air, water, and soil resources that can arise from improper waste management.

The other options represent lower thresholds that would categorize generators as small quantity generators or very small quantity generators, which have less stringent regulatory requirements, as they produce comparatively smaller amounts of hazardous waste that are typically easier to manage and monitor.
