State compliance is monitored by EPA inspections. In the case that waste management guideline standards are not met, action against the site will be taken. Compliance errors may be corrected by enforced cleanup directly by the site responsible for the waste or by a third party hired by that site. Prior to the enactment of the Clean Water At (1972) and RCRA, open dumping or releasing wastewater into nearby bodies of water were common waste disposal methods. The negative effects on human health and environmental health led to the need for such regulations. The RCRA framework provides specified subsections defining nonhazardous and hazardous waste materials and how each should be properly managed and disposed of. Guidelines for the disposal of nonhazardous solid waste includes the banning of open dumping. Hazardous waste is monitored in a "cradle to grave" fashion; each step in the process of waste generation, transport and disposal is tracked. The EPA now manages 2.96 million tons of solid, hazardous and industrial waste. Since establishment, the RCRA program has undergone reforms as inefficiencies arise and as waste management processes evolve.
