CERCLA and RCRA are the two main laws governing hazardous waste in the US. CERCLA, also known as Superfund, establishes liability for cleaning up abandoned hazardous waste sites and ensures that those responsible pay for remediation. RCRA is a regulatory statute that gives EPA oversight of hazardous waste from generation to disposal in order to prevent future Superfund sites and protect human health and the environment. Both laws reinforce each other but still have weaknesses, such as inadequate funding for Superfund cleanups and loopholes allowing toxic materials to avoid regulation.
