Hazardous Waste Sites

A hazardous waste site is an area of land or water, contaminated by hazardous waste that poses a risk to human health or the environment.

This hazardous waste looks very different before and after cleanup.

Abandoned or uncontrolled hazardous waste sites that EPA identifies for cleanup are known as Superfund sites. Such sites are on public and private property.

Hazardous Waste Generators

Many businesses generate hazardous waste as a byproduct of their production operations, store it for a short time, and then send it to a treatment, storage, or disposal (TSD) facility.

A generator is any person who produces a hazardous waste as listed or characterized in 40 CFR 261. The volume of hazardous waste each generator produces in a calendar month determines which regulations apply to that generator.

Under RCRA, hazardous waste generators are the first link in the hazardous waste management system. All generators must determine if their waste is hazardous and must oversee the ultimate fate of the waste. They must document that the hazardous waste they produce is properly identified, managed, and treated prior to recycling or disposal. The degree of regulation that applies to each generator depends on the amount of waste that a generator produces.
