RCRA limit

Table 16.1 provides the maximum allowable limits to determine whether the waste needs prior treatment and if it is treated, whether the treatment is successful or not. The allowable limit is called the RCRA limit for the former and the Universal Treatment Standard (UTS) for the latter. Details of this test may be found in Ref. [5].

The volatilization and leaching of various forms of mercury (elemental, mercuric sulfide, mercuric oxide, and mercurous oxide) from soils or wastes was examined using the headspace method for volatilization and the Resource and Conservation Recovery Act (RCRA) leaching protocols for leaching through soil to determine if the leachates exceeded the RCRA limit of 200 g/L (ppb) (Willett et al. 1992). With the exception of mercuric sulfide, the other forms of mercury increased in concentrations in the headspace vapor and in the leachate as the soil concentrations increased, although the elemental mercury... 

RCRA incinerator regulations include adrninistrative as weU as performance standards. Administrative standards include procedures for waste analysis, inspection of equipment, monitoring, and facihty security. Steps needed to meet adrninistrative standards are outlined ia the permit apphcation performance standards are demonstrated during a trial bum. Trial bum operating conditions are included in the permit to assure ongoing compliance with the performance standards. Performance standards include destmction and removal efficiency (DRE), particulate emissions limits, products of incomplete combustion emission limits, metal emission limits, and HCl and Cl emission limits (see Exhaust CONTROL, INDUSTRIAL). 

The overall requirement is 1.0—2.0 s for low energy waste compared to typical design standards of 2.0 s for RCRA ha2ardous waste units. The most important, ie, rate limiting steps are droplet evaporation and chemical reaction. The calculated time requirements for these steps are only approximations and subject to error. For example, formation of a skin on the evaporating droplet may inhibit evaporation compared to the theory, whereas secondary atomization may accelerate it. Errors in estimates of the activation energy can significantly alter the chemical reaction rate constant, and the pre-exponential factor from equation 36 is only approximate. Also, interactions with free-radical species may accelerate the rate of chemical reaction over that estimated solely as a result of thermal excitation therefore, measurements of the time requirements are desirable. 

The Resource Conservation and Recovery Act (RCRA) controls the disposal of ha2ardous waste. SARA Tide III governs the toxic iaventory and emission reporting the Clean Water Act (CWA) sets the limits for metals that can be present ia water discharge and the Clear Air Act (CAA)...

Non-RCRA-permitted TSDs and waste treatment activities not covered by RCRA (e.g., wastewater treatment facilities permitted under the Clean Water Act) are not covered by HAZWOPER, except for emergency response and some limited waste management operations. Specific HAZWOPER elements are assimilated into the existing health and safety program based on hazard analyses. Worker protection requirements are met through existing health and safety plans [1].

Ihe implementation of the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) has underscored a number of the weaknesses in our capabilities to measure the chemical characteristics of wastes. We are now being called upon to identify and quantify with unprecedented sensitivity hundreds of chemicals found in many types of materials within waste sites, near discharges of hazardous contaminants, and in the surrounding environments. Extrapolations from a limited number of measurements must indicate the general environmental conditions near waste sites. The measurements have to be made faster and cheaper than ever before, with the precision and bias of each measurement fully documented. Thus, the technical challenges facing the monitoring community are substantial.

Emissions from hazardous waste combustors are regulated under two statutory authorities RCRA and the CAA. The MACT standards set emission limitations for dioxins, furans, metals, particulate matter, total chlorine, hydrocarbons/carbon monoxide, and destruction and removal efficiency (DRE) for organics. Once a facility has demonstrated compliance with the MACT standards by conducting its comprehensive performance test (CPT) and submitting its notification of compliance (NOC), it is no longer subject to the RCRA emission requirements with a few exceptions. RCRA-permitted facilities, however, must continue to comply with their permitted emissions requirements until they obtain modifications to remove any duplicative emissions conditions from their RCRA... 

Both RCRA and CERCLA contain provisions that allow U.S. EPA to require persons contributing to an imminent hazard to take the necessary actions to clean up releases. RCRA s imminent and substantial endangerment provision addresses nonhazardous as well as hazardous solid waste releases. The authority under CERCLA is essentially the same, except that CERCLA s authority to abate an imminent or substantial danger to public health or the environment is limited to hazardous substance releases. In an enforcement action, the RCRA and CERCLA imminent hazard provisions may be used in tandem to ensure adequate protection of human health and the environment.

Discharges to surface waters from an RCRA-permitted facility must comply with the limitations set forth in an NPDES permit. This means that either the facility itself has obtained an NPDES permit or the wastes meet CWA pretreatment standards and have been transported to a POTW. 

FIFRA controls limit the level of toxic pesticides that are produced, and thereby reduce the amount of waste that needs to be managed under RCRA. 

Another by-product of the combustion process is ash. Ash is an inert solid material composed primarily of carbon, salts, and metals. During combustion, most ash collects at the bottom of the combustion chamber (bottom ash). When this ash is removed from the combustion chamber, it may be considered hazardous waste via the derived-from rule or because it exhibits a characteristic.17 Some ash, however, is carried up with the gases as small particles, or PM. These particles are also collected in the APCD in accordance with RCRA-established limits. 

The Safe Drinking Water Act (SDWA), enacted in 1974 to assure high-quality water supplies through public water system. The act is truly the first federal intervention to set the limits of contaminants in drinking water. The 1986 amendments came two years after passage of the Hazardous and Solid Waste Amendments (HSWA) or the RCRA amendments of 1984. As a result, certain statutory provisions were added to these 1986 amendments to reflect the changes made in the underground injection control (UIC) systems.
