The regulatory requirements for these types of storage practices are found in 40 CFR 264 and 40 CFR 265 . Policies related to the storage of hazardous waste are found in the RCRA Permit Policy Compendium and in RCRA Online . Disposal Disposal is the placement of waste into or on the land. Disposal facilities are usually designed to permanently contain the waste and prevent the release of harmful pollutants to the environment. The most common disposal technology used for both municipal and hazardous waste is landfilling.
Landfills are waste management structures where waste is placed into the land.
Both municipal and hazardous waste landfills usually have liner systems and leachate collection systems to prevent contamination of the ground water under the landfill. Groundwater monitoring is also generally required along with corrective action if releases of hazardous pollutants occur. Once the landfills stop receiving waste they are required to close by putting an impermeable cover on the landfill to prevent rainwater from entering. Hazardous waste landfill standards are found in 40 CFR 264 and 40 CFR 265 . Another disposal technology that is commonly used to manage liquid hazardous waste is injection wells.
