Land disposal restrictions (LDR) To reduce the hazards posed by permanently land-disposed waste, this program requires effective and expeditious hazardous waste treatment.

The mixture and derived-from rules apply differently to listed and characteristic wastes. A mixture involving characteristic wastes is hazardous only if the mixture itself exhibits a characteristic. Similarly, treatment residues and materials derived from characteristic wastes are hazardous only if they themselves exhibit a characteristic. Unlike listed hazardous wastes, characteristic wastes are hazardous because they possess one of four unique and measurable properties. U.S. EPA decided that once a characteristic waste no longer exhibits one of these four dangerous properties, it no longer deserves regulation as hazardous. Thus, a characteristic waste can be made nonhazardous by treating it to remove its hazardous property however, U.S. EPA places certain restrictions on the manner in which a waste can be treated. One can learn more about these restrictions in the U.S. EPA Land Disposal Restrictions Module Handlers who render characteristic wastes nonhazardous must consider these restrictions when treating wastes to remove their hazardous properties.

Because endrin and endrin aldehyde are listed as hazardous substances, disposal of wastes containing these compounds is controlled by a number of federal regulations (see Chapter 7). Land disposal restrictions apply to wastes containing endrin or endrin aldehyde (EPA 1986d, 1987b). Chemical treatment (reductive dechlorination) or incineration are possible disposal methods (HSDB 1995 IRPTC 1985). Past disposal...

Treatment residuals meet strict land disposal restrictions or delisting requirements. 

A key advantage of this technology is that little excavation is required to treat the soil. Since the soil is treated in place, the waste is not subject to any land disposal restrictions that might be applicable if excavation were required. Also, a unique feature of this technology is that it can treat contaminated soils under and around existing structures. 

Supercritical carbon dioxide extraction (SCDE) is an ex sitn process for the treatment of low-level solid mixed and land disposal restricted (LDR) wastes. SCDE can extract hazardons solvents from waste snbstrates to prodnce land-disposable, low-level wastes. The process employs the snpercritical finid carbon dioxide as a solvent. This finid is noncombustible, nontoxic, and environmentally safe. In its supercritical state, carbon dioxide can dissolve organic contaminants allowing the fluid to quickly penetrate and facilitate transfer out of a contaminated matrix. 

This technology has been used to treat polychlorinated biphenyls (PCBs), halogenated and nonhalogenated solvents, semivolatile organic compounds (SVOCs), polynuclear aromatic hydrocarbons (PAHs), pesticides, herbicides, fuel oils, benzene, toluene, ethylbenzene, and xylenes (BTEX), and mercury. This system has also treated Resource Conservation and Recovery Act (RCRA) hazardous wastes such as petroleum refinery wastes and multisource leachate treatment residues to meet RCRA Land Disposal Restrictions (LDR) treatment standards.
