Across the USA, there are thousands of contaminated sites where hazardous materials have been dumped in inadequate locations. The EPA is responsible for cleaning those sites up and making them usable again. When the EPA identifies a site that needs to be cleaned up, it’s referred to as a Superfund site.
Waste can be broken down into types, based on how the law sees it and how it needs to be processed. Longstanding U.S. laws like 40 CFR part 261.31 define certain types of waste as hazardous. Other regulations define where certain types of waste have to be sent for disposal. Making your way through this maze can be complex, but it doesn’t have to be.
