Land disposal restrictions requirements

Characteristics of solid and liquid residuals in relation to land disposal restrictions requirements using the toxic constituent leaching procedure and analysis of the underlying hazardous constituents such that implementation of proper disposal options can be ensured. 

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

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.

The restrictions on the land disposal of many wastes have increased the cost of hazardous waste disposal. The land disposal restrictions that affect metal fabricators have been in effect for several years. For example, the restrictions on the land disposal of liquid wastes containing toxic metals and/or acids began on January 1,1984 (Section 66905 CCR). These restrictions have caused increases in disposal costs since these wastes now require some form of treatment prior to land disposal. These increased waste disposal costs are viewed as a driving force for the metal finishing industry to implement waste reduction technologies. 

The RCRA metal-containing aqueous wastes include characteristic wastes (D wastes) and the listed wastes (K and F wastes). The characteristic wastes are those containing any of the eight RCRA metals above the concentrations (EP Toxicity levels) identified in the Code of Federal Regulations (40 CFR Part 261.24). The F and K wastes are source-specific wastes and do not require any minimum metal concentration to be a RCRA hazardous waste. Table 1 identifies the RCRA waste codes chat have aqueous wastes with metals, and associated effective daces for land disposal restrictions.

Analytical requirements for complying with land disposal restrictions. 

Regulatory Requirements EPA s Land Disposal Restrictions (LCRs) specify incineration as a best demonstrated available technology (BDAT) for many types of wastes, meaning that these wastes must be incinerated prior to land disposal. Also, incineration results were used to set concentration-based BDAT standards for many contaminants and incineration probably has the best chance of continuing to meet these standards. 

Also of note for this report are the RCRA Land Disposal Restrictions (LDRs)." The LDR program was mandated by the RCRA Hazardous and Solid Waste Amendments of 1984. In essence, LDRs are treatment standards for listed and characteristic hazardous waste that must be achieved prior to land disposal. Treatment standards under the LDR program are established on the basis of the best demonstrated available technology and are therefore technology-based (as opposed to risk-based). Although LDR standards are technology-based, EPA has proposed, as part of HWIR, to cap LDR treatment standards with the HWIR risk-based levels. In this manner, treatment would not be required below those levels necessary to minimize risk to human health or the environment. 

Hazardous waste must be treated in accordance with the land disposal restriction (LDR) requirements before being disposed. 

If EDS liquid wastes are determined to be hazardous under the federal RCRA program (via the RCRA characteristics), RCRA s land disposal restrictions (LDRs) apply, and the wastes must be treated to meet specific requirements. 

In all states, the EDS neutralents could be considered characteristic hazardous wastes under RCRA. With some exceptions, a hazardous waste may only be treated, stored, or disposed of in a RCRA-permitted TSDF. In addition, any treatment technology must meet RCRA requirements, such as the Land Disposal Restrictions (LDRs) (40 CFR 268). In accordance with the LDRs, wastes must meet certain treatment standards prior to land disposal. These restrictions provide for additional protection of human health and the environment, but they add considerably to the cost and time required to treat and dispose of the waste stream. Other standards must also be met, such as those associated with treatment facihty operation and closure. 

Off-site disposal in a landfill can be the most cost-effective option for certain wastes. It is still the easiest, cheapest option in most cases for handling small amounts of soil or waste. The cost of landfilling soils or solid wastes depends on the waste classification, treatment required to meet land disposal restrictions, if any, and proximity to a disposal facility. The decision to dispose of soil must balance these cost factors against the potential liabilities from transportation and disposal of contaminated material. 

Not all hazardous wastes can be put in a landfill. In the United States, Land Disposal Restrictions promulgated under RCRA (40 CFR 268) require that most hazardous wastes meet certain concentration limits or be treated using a specified technology before disposal. Certain hazardous wastes cannot be placed in a landfill under any circumstances. 

Whether or not a waste is considered hazardous or quahfies for an exemption to RCRA, it s still important to rmderstand the impact the waste can have on the environment and human health. Fruther, you will need to know and rmderstand any land disposal restrictions that apply to the waste you generate and any rmiversal or special waste rules (such as used oil rules). In addition, you may need to follow specific state waste requirements for hazardous wastes. Also, be aware that many environmental groups are lobbying the government to remove the exemptions for the industry, which cordd resrdt in oil and gas operations having to comply with the requirements of 40 CFR Parts 261 - 280 in the futme. 

Other important RCRA regulatory requirements Land disposal restrictions (LDRs)... 

This series of prohibitions restricts how wastes subject to LDR requirements are handled. The most visible aspect of the LDR program is the disposal prohibition, which includes treatment standards, variances, alternative treatment standards (ATSs), and notification requirements. Land disposal means placement in or on the land, except in a corrective action unit, and includes, but is not limited to, placement in a landfill, surface impoundment, waste pile, injection well, land treatment facility, salt dome formation, salt bed formation, underground mine or cave, or placement in a concrete vault, or bunker intended for disposal purposes. The other two components work in tandem with the disposal prohibition to guide the regulated community in proper hazardous waste management. The dilution prohibition ensures that wastes are properly treated, and the storage prohibition ensures that waste will not be stored indefinitely to avoid treatment. 

Each of these states has adopted the basic EPA hazardous waste management program, including regulations for identification and listing of hazardous wastes requirements applicable to generators and transporters of hazardous waste requirements for facilities that treat, store, or dispose of hazardous waste and restrictions for the land disposal of specific hazardous wastes. 

Wastes defined as hazardous under RCRA include characteristic and listed wastes. An RCRA-defined hazardous waste is a waste that appears on one of four lists (F list, K list, U list, or P list) or exhibits at least one of four characteristics (ignitability, corrosivity, reactivity, or toxicity). Criteria for identifying characteristic hazardous wastes are included in Title 40, CFR part 261, subpart C. Listed wastes from industrial sources are itemized in 40 CFR part 261, subpart D. Other regulations that are relevant to the technology include the requirement to characterize the waste for a hazardous waste generator (40 CFR part 262.11), the requirement to determine if the hazardous waste is restricted from land disposal [40 CFR 268.7(a)], requirements for on-site storage of waste for up to 90 days [40 CFR 262.34(a)], or 40 CFR 264.553 for storage of waste in a temporary unit for up to 1 year prior to disposal. 

In 1992, the WIPP Land Withdrawal Act (Public Law 102-579) established prerequisites for initial receipt and permanent disposal of TRU wastes at WIPE The Act also specified the statutory, regulatory, and other requirements and restrictions applicable to the WIPP facility and its operations. Significantly, EPA was designated as a primary independent regulator at WIPP with authority to determine whether the repository is suitable as a long-term disposal facility.
