Best demonstrated available technology

Scenario 1 The first phase of the roll out would be of around 3 years (2013-2016). It would cover mainly the class I cities.2 It is desired that the collection and recycling program uses the best demonstrated available technology (BDAT) option which are - DTCs to collect and crush lamps without releasing mercury in transit and recycling facility having mercury recovery facility. 

Meets and exceeds U.S. Environmental Protection Agency s (EPA s) Best Demonstrated Available Technology (BDAT) standards for refinery wastes. 

These metal leachate limitations are extremely difficult to meet with the Best Demonstrated Available Technology (BDAT) which is chemical stabilization technology proposed by the Federal EPA. The fact that no limit was proposed for cyanide adds uncertainty to chemical stabilization. TSD facilities do not want to put mixed wastes containing cyanides into their secure landfills which may have to be removed at a later date. Note that a 1972 U.S. silver dollar fails the TCLP test due to nickel. 

Best demonstrated available technology (BDAT) According to the US Environmental Protection Agency, the best commercial technology for treating a specific hazardous waste. For example, vitrification is the BDAT for treating arsenic in soils (see Chapter 7). 

The NCP contains several criteria that are Intended to guide decisions on the standards to be achieved in Individual remedial actions. Among these the most important are the threshold criteria, which include (1) a general requirement to protect human health and the environment and (2) cleanup standards which have applicable or relevant and appropriate requirements (ARAR). Under the ARAR approach, EPA can use standards from other federal and state statutes (e.g., CWA, SDWA, RCRA) on a case-by-case basis when these requirements are applicable or relevant and appropriate. For example, RCRA land-disposal restorations (LDR) may be relevant and applicable" if a CERCLA remedial action involves RCRA hazardous waste and the waste or its hazardous residue is to be land disposed. In this case, the RCRA LDR standards that are based on the best demonstrated available technology (BDAT) may apply. 

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. 

Evaluation of Solidification/Stabilization as a Best Demonstrated Available Technology for Contaminated Soils... 

Chloroform is a U044 hazardous waste. A concentration-based limit of 5.6 mg/kg has been set by the EPA for land disposal. The standard was established based on the performance of incineration, which is a best (demonstrated) available technology. 

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. 

The burning of pulverized coal in electric power plants produces sulfur dioxide (SO2) gas emissions. The 1990 Clean Air Act and its subsequent amendments mandated the reduction of power plant SOj emissions [66-70]. The Best Demonstrated Available Technology (BDAT) for reducing SOj emissions is wet scrubber flue gas desulfurization (FGD) systems. These systems are designed to introduce an aUcahne sorbent consisting of lime or limestone in a spray form into the exhaust gas system of a coal-fired boiler. The aUcaU reacts with the SOj gas and is collected in a liquid form as calcium sulfite or calcium sulfate slurry. The calcium sulfite or sulfate is allowed to settle out as most of the water is recycled [66-80]. 

WAO is currently used in more than 300 commercial installations, and the Environmental Protection Agency (EPA) has specified WAO as a best-demonstrated available technology for the treatment of hazardous wastewater containing...
