Section 261.32 (40 CFR 261.32) as K026, stripping still tails from the production of methyl ethyl pyridine. These BDAT treatment standards are being established in accordance with the amendments to the Resource Conservation and Recovery Act (RCRA) of 1976, enacted by the Hazardous and Solid Waste Amendments (HSWA) of November 8, 1984. BDAT treatment standards will be effective no later than May 8, 1990, and on or after the effective date, compliance with these BDAT treatment standards will be a prerequisite under 40 CFR Part 268 for placement of the waste in land disposal units. This background document provides the Agency's rationale and techni- cal support for selecting the constituents for proposed regulation in K026 and for developing treatment standards for these constituents. The document also provides waste characterization data that serve as a basis for determining whether a variance from a treatment standard may be warranted for a particular type of K026 that is more difficult to treat than the wastes that were ana- lyzed in developing treatment standards for K026. The Agency's legal authority and promulgated methodology for estab- lishing treatment standards and the petition process necessary for requesting 1-1 ------- a variance from the treatment standards are summarized in EPA's Methodology for Develooine BOAT Treatment Standards (Reference 1). This background document presents waste-specific information on the number and locations of facilities that may be affected by the land disposal restrictions for K026, the processes generating this waste, the waste charac- terization data, the technologies used to treat the waste (or similar wastes, if any), and the treatment performance data on which the proposed treatment standards are based (Sections 2.0 - 4.0). This document also explains how EPA determines BDAT, selects constituents to be regulated, and calculates treat- ment standards (Sections 5.0 - 7.0). Under 40 CFR 261.32, wastes identified as K026 are listed as follows: K026 - Stripping still tails from the production of methyl ethyl pyridine. The four-digit Standard Industrial Classification (SIC) code associated with the production of methyl ethyl pyridine is 2869. The Agency is not aware of any domestic facilities that generate K026. The Agency is proposing one organic constituent for regulation in nonwastewater and wastewater forms of K026. To determine the applicability of the treatment standards, wastewaters are defined as wastes containing less 1-2 ------- than 1% (weight basis) total suspended solids (TSS) and less than 1% (weight basis) total organic carbon (TOC). Wastes not meeting this definition are classified as nonwastewaters and must comply with nonwastewater treatment standards. The Agency does not have any performance data on the treatment of K026. Treatment performance tests for this waste have not been pursued because the Agency believes that adequate treatment performance data are available from similar wastes previously tested by the BOAT Land Disposal Restrictions Program. Therefore, treatment performance data were transferred to K026 from another previously tested waste. For nonwastewater and wastewater forms of K026, proposed BOAT treatment standards are based on treatment performance data transferred from incineration of the RCRA Blend waste that was co-treated with K019. Tables 1-1 and 1-2 at the end of this section list the proposed BDAT treatment standards for nonwastewater and wastewater forms of K026. These proposed treatment standards are based on the total concentration of pyridine in the waste. The units used for total constituent concentration are mg/kg The term "total suspended solids" (TSS) clarifies EFA's previously used terminology of "total solids" and "filterable solids". Specifically, total suspended solids is measured by Method dried at 103-105°C) in Standard Methods for 1 Wastewater. Sixteenth Edition (Reference 2). total suspended solids is measured by Method 209C (total suspended solids dried at 103-105 C) in Standard Methods for the Examination of Water and 1-3 ------- (parts per million on a weight-by-weight basis) for K026 nonwastewaters, and mg/1 (parts per million on a weight-by-volume basis) for K026 wastewaters. If the concentrations of the constituent proposed for regulation in K026 nonwastevaters and wastewaters, as generated, is lower than or equal to the proposed treatment standards, then treatment of the waste would not be required prior to "land disposal," as defined by 40 CFR Part 268. EPA is also proposing to establish a method of treatment as the treatment standard for nonwastewater and wastewater forms of K026 as an alternative to specifying numerical treatment standards. The Agency is proposing this alternate treatment standard because it is uncertain whether other constituents, which may not be controlled for by regulation of the BDAT List constituent proposed for regulation, are present in K026, due to a lack of characterization data for K026. These alternative treatment standards are shown in Tables 1-1 and 1-2, for nonwastewater and wastewater forms of K026, respectively. ------- Table 1-1 PROPOSED BDAT TREATMENT STANDARDS FOR K026 NONWASTEWATERS Maximum for Any Single Grab Sample Total Concentration BDAT List Constituent (me/kg) 39.

A search of available data indicates that MEP is no longer produced domestically. MEP is among the pyridine bases that are produced commercially by synthesis rather than by isolation from coal tar. Figure 2-1 includes a generic process diagram for MEP production. Acetaldehyde and sulfuric acid are reacted to form crude paraldehyde that can be used to produce MEP or sent on for refinement. To produce MEP, the crude paraldehyde is preheated and reacted with ammonia acetate in the presence of an aluminum oxide, aluminum fluoride, or cobalt chloride catalyst. The resulting product stream is then transferred to an ammonia stripping still for ammonia recovery, and then to a decanter. The MEP layer is further refined in a batch still. Residue from the decanter is processed in a water stripping still. The stripping still tails comprise the waste stream of concern. 2-1 ------- 2.2 Waste Characterization Available data sources (Reference 3) indicate the following general composition for K026: Constituent Concentration (%) Faraldehyde 50 Pyridines 3 Picolines 3 Sulfuric Acid 6 Acetates 5 Water 33 Total: 100% The only specific K026 characterization data that the Agency is aware of indicate that pyridine is present in the untreated waste at 32,500 ppm. Concentrations of other BOAT List constituents were not reported. , 2-2 ------- To Paraldehyde Refinement Ammonia Acetate Acetaldehyde Sulfuric Acid Crude Paraldehyde N) I +- HEP To Further Processing ^ To Storage for Further Processing Figure 2-1. Flow Diagram for the Production of Methyl Ethyl Pyridine (MEP) ------- 3.0 APPLICABLE AND DEMONSTRATED TREATMENT TECHNOLOGIES This section discusses the technologies that are applicable to treatment of K026 nonwastewaters and wastewaters and determines which, if any, of the applicable technologies can be considered demonstrated for the purpose of establishing BDAT. To be applicable, a technology must theoretically be usable to treat the waste in question or a waste that is similar in terms of parameters that affect treatment selection. (Detailed descriptions of technologies that are applicable to listed hazardous wastes are provided in EPA's Treatment Technol- ogy Background Document (Reference 4.) To be demonstrated, a technology must be employed in full-scale operation for treatment of the waste in question or a similar waste. Technologies available only at pilot- or bench-scale opera- tions are not considered in identifying demonstrated technologies. 3.1 Applicable Treatment Technologies The following subsections present applicable treatment technologies for nonwastewater and wastewater forms of K026. -.i. A;,; ;ci . • ..^r • Nonwastewaters Since nonwastewater forms of K026 consist primarily of organic compounds (as shown in Section 2.0 of this document), applicable treatment 3-1 ------- technologies include those that destroy or reduce the total amount of various organic compounds in the waste. The Agency has identified the following treatment technologies as potentially applicable for these wastes: (1) incineration (fluidized bed and rotary kiln); (2) solvent extraction followed by incineration or recycle of the extract; and (3) critical fluid extraction followed by recycle or incineration of the contaminated solvents. These treatment technologies were identified based on current waste treatment practices and engineering judgment. Incineration. Incineration is a destruction technology in which energy, in the form of heat, is transferred to the waste to destabilize chemical bonds and destroy organic constituents. In a fluidized bed incinera- tor, waste is injected into the fluidized bed material (generally sand and/or incinerator ash), where it is heated to its ignition temperature. Heat energy from the combustion reactions is then transferred back to the fluidized bed. Ash is removed periodically during operation and during bed change-outs. In a rotary kiln incinerator, wastes are fed into the elevated end of the kiln, and the rotation of the kiln mixes the waste with hot gases to heat the waste to its ignition temperature. Ash is removed from the lower end of the kiln. Combustion gases from the kiln enter the afterburner for com- plete destruction of organic waste constituents. Other wastes may also be injected into the afterburner. 3-2 ------- Combustion gases from the fluidized bed or kiln afterburner are then fed to a scrubber system for cooling and removal of entrained particulates and acid gases, if present. In general, two residuals are generated by incinera- tion processes: ash and scrubber water. Solvent Extraction. Solvent extraction is a separation technology in which organics are removed from the waste due to greater constituent solubility in the solvent phase than in the waste phase. This technology results in the generation of two treatment residuals: a treated waste resid- ual and an extract. The extract may be recycled or further treated by incin- eration. Critical Fluid Extraction. :Critical fluid extraction is a solvent extraction technology in which the solvent is brought to its critical state to aid in the extraction of organic constituents from the wastes. After the extraction step, the solvent (liquefied gas at its critical state) is brought to its normal condition in the gaseous state and generates a small volume of extract that is concentrated in organic constituents. This technology results in the generation of two treatment residuals: a treated waste and an extract. The extract may be recycled or further treated by incineration. Wastewaters Since wastewater forms of K026 may contain organic constituents at treatable concentrations, applicable technologies include those that destroy 3-3 ------- or reduce the total amount of various organic compounds in the waste. The Agency has identified the following treatment technologies as potentially applicable for treatment of K026 wastewaters: (1) incineration; (2) steam stripping; (3) biological treatment; (4) carbon adsorption; and (5) solvent extraction. Incineration. Incineration of wastewaters in a rotary kiln or fluidized bed is identical to that for nonwastewaters described previously in this section. In addition, liquid injection incineration may also be an applicable technology for treatment of K026 wastewaters. In a liquid injection incinerator, liquid wastes are atomized and injected into the incinerator. Combustion gases from the incinerator are then fed to a scrubber system for cooling and removal of entrained particulates and acid gases, if present. In general, only wastes with low or negligible ash content are amenable to liquid injection incineration. Therefore, the tech- nology generally does not result in the generation of an ash residual. ft tripping . Steam stripping is a separation technology in which organics are removed from the waste by volatilization through the "Application of heat.01 This technology results rftiathe formation of two treat- ment residuals: a treated waste extract and a treated effluent. The treated waste extract and the treated effluent may require further treatment by incineration, and carbon adsorption or biological treatment, respectively. 3-4 ------- Biological Treatment. Biological treatment is a destruction tech- nology in which organic constituents in wastewaters are biodegraded. This technology results in the formation of two treatment residuals: a treated effluent and a waste biosludge. The treated effluent and the waste biosludge may require further treatment for metals by chemical precipitation and stabi- lization, respectively. Carbon Adsorption. Carbon adsorption is a separation technology in which organic constituents in wastewaters are selectively adsorbed onto activated carbon. This technology results in the formation of two treatment residuals: a treated effluent and spent activated carbon. The treated effluent may require further treatment for metals by chemical precipitation. The spent carbon may require further treatment by incineration. Solvent Extraction. Solvent extraction of wastewaters is identical to that for nonwastewaters described previously in this subsection. 3.2 r Demonstrated Treatment Technologies ; r . The Agency is not aware of any facilities that treat K026 nonwaste- waters as^or wastewaters. Hpwever, rotary kiln incineration is demonstrated for similar wastes, as discussed in Section 4.0 of this document. The Agency is not aware of any other technologies that are demon- strated for treatment of K026. 3-5 ------- 4.0 TREATMENT PERFORMANCE DATA BASE This section presents the treatment performance data that were used to develop proposed treatment standards for nonwastewater and wastewater forms of K026. Where data are not available on the treatment of the specific waste of concern, the Agency may elect to transfer performance data from a demon- strated treatment technology that treats a similar waste or wastes. EPA's methodology for the transfer of treatment performance data is provided in EPA's Methodology for Developing BOAT Treatment Standards (Reference 1). Transfer of treatment performance data is technically valid in cases where the untested wastes are generated from similar industries or similar processing steps, or have similar waste characteristics affecting treatment selection and performance that are similar to those of the tested wastes. The Agency does not have any treatment performance data for treat- ment of K026 nonwastewaters or wastewaters. However, treatment performance data were available from other wastes previously tested by EPA and were transferred to develop proposed treatment standards for K026. Sources of treatment performance data for potential transfer to K026 include wastes previously tested by incineration (including rotary kiln and fluidized bed incineration). Incineration was identified as applicable and demonstrated for treatment of these wastes, as discussed in Section 3.0 of this document. 4-1 ------- Previous incineration tests conducted by the Agency are listed in Table 4-1 at the end of this section. EPA examined the wastes incinerated in these tests to identify the best data source(s), if any, for transfer of treatment performance data to K026 nonwastewaters and wastewaters. Specifi- cally, EPA examined (1) whether the untested K026 is generated from a similar industry or processing step and (2) whether the waste has similar waste characteristics as those previously tested wastes. Wastes included in Tests 3, 4, 5, 11, 12, 13, and 14 are generated by the organic chemicals industry. Like K026, wastes incinerated in Tests 3, 4, 5, 11, and 14 were generated by distillation or some other type of separa- tion process. Of the wastes generated by a process similar to that generating K026, those incinerated in Tests 3, 4, and 14 contain nitrogenated compounds and are, therefore, most structurally similar to K026. The wastes incinerated in these tests are also similar to K026 in that they are all organic wastes. The constituents in the RCRA Blend waste incinerated in Test 4 are more similar to K026 than those in Tests 3 and 14 with respect to structure and physical properties that affect the treatment performance of incineration, such as boiling points and bond dissociation energies. In addition, the RCRA Blend waste incinerated in Test 4 is expected to have a similar thermal conductivity to K026. Therefore, treatment performance similar to that achieved for the RCRA Blend waste could be achieved for K026. 4-2 ------- Based on the similarities discussed above, a treatment standard for the constituent being proposed for regulation in K026 nonwastewaters and wastewaters was developed based on treatment performance data transferred from rotary kiln incineration of the RCRA Blend waste that was co-incinerated with K019 in Test 4 (Reference 5). K019 and three other wastes, referred to as "RCRA Blend", "PCB Blend", and "mercaptan-contaminated waste", were treated in Test 4. K019, RCRA Blend waste, FCB Blend waste, and mercaptan-contaminated waste comprised approximately 20%, 23%, 41%, and 16%, respectively, of the waste treated. K019 and RCRA Blend were fed to the rotary kiln; PCB Blend and mercaptan- contaminated waste were fed to the afterburner (secondary combustor). The ash generated from rotary kiln incineration results from treatment of the K019 and RCRA Blend wastes only, while scrubber water results from treatment of all four wastes fed to the incinerator. The ash data from the incineration of K019 and RCRA Blend waste were transferred to K026 nonwastewaters, and the scrubber water data from incineration of all four wastes were transferred to K026 wastewaters. Tables 4-2 and 4-3 present the BDAT List constituents detected in the untreated wastes and in the kiln ash residual for six sample sets collected by EPA from the rotary kiln incineration treatment system. Table 4-4 presents BDAT List constituents detected in the scrubber water residual for six sample sets collected by EPA from the same incineration system. Design and operating data are presented in Table 4-5 for each sample set. All tables are presented at the end of this section. 4-3 ------- Table 4-1 WASTES TESTED BY INCINERATION AND SAMPLED BY EPA Test Number 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Waste Code(s) K001 - Pentachlorophenol waste K001 - Creosote waste K011, K013, K014 K019 K024 K037 K048, K051 K087 K101 K102 F024 K015 D014, D016, P059*.

For a treatment technology to be identified as BDAT, the treatment performance data are first screened to determine whether they represent a well-designed and well-operated treatment system, whether sufficient analyti- cal quality assurance/quality control measures were employed to ensure the accuracy of the data, and whether the appropriate measures of performance were used to assess the performance of the particular treatment technology. i The treatment performance data and the design and operating data collected during the RCRA Blend waste treatment test (Test 4) were reviewed for the points described above. The appropriate measure of performance (total constituent concentration) was used to assess the treatment system. Addi- tionally, the Agency had no reason to believe that this treatment system was not well-designed and well-operated, or that insufficient analytical quality assurance/quality control measures were employed in generating treatment performance data. An available treatment technology is one that (1) is not a proprie- tary or patented process that cannot be purchased or licensed from the propri- etor (i.e., it must be commercially available), and (2) substantially 5-1 ------- diminishes the toxicity of the waste or substantially reduces the likelihood of migration of hazardous constituents from the waste. The technology that is demonstrated for treatment of K026, incineration, is considered to be commer- cially available and to provide substantial treatment of the waste. There- fore, incineration is "available" for treatment of K026. In summary, incineration has been determined to be demonstrated and available for treatment of nonwastewater and wastewater forms of K026. However, because the Agency does not have treatment performance data for any other demonstrated and available technologies treating K026 or similar wastes, this treatment technology is considered to be the best. Therefore, the best demonstrated available technology (BOAT) for K026 has been determined to be incineration. 5-2 ------- 6.0 SELECTION OF CONSTITUENTS PROPOSED FOR REGULATION The Agency has developed a list of hazardous constituents (the BDAT Constituent List, presented in EPA's Methodology for Developing BDAT Treatment Standards (Reference 1)) from which constituents to be regulated are selected for regulation. EPA may revise this list as additional data and information become available. The list is divided into the following categories: vola- tile organics, semivolatile organics, metals, inorganics other than metals, organochlorine pesticides, phenoxyacetic acid herbicides, organophosphorus insecticides, PCBs, and dioxins and furans. This section presents the ration- ale for the selection of pyridine for proposed regulation in wastewater and nonwastewater forms of K026. Generally, constituents selected for proposed regulation must satisfy the following criteria: (1) The constituent must be on the BDAT List of regulated constitu- ents. Presence on the BDAT List means that approved methods to analyze for the constituent in treated waste matrices exist. (2) The constituent must be present in. or be suspected of being present in. the untreated waste. For example, in some cases, analytical difficulties (such as masking) may prevent a con- stituent from being identified in the untreated waste, but its identification in a treatment residual may lead the Agency to conclude that it is present in the untreated waste. The Agency reviewed all available K026 characterization data for these criteria. (These data are presented in Table 2-1 of this document.) Pyridine was the only BDAT List constituent for which analytical results were quantified above the detection limit and reported. Accordingly, pyridine was 6-1 ------- the only BOAT List constituent selected for proposed regulation in nonwaste- water and vastewater forms of K026. 6-2 ------- 7.0 CALCULATION OF PROPOSED BOAT TREATMENT STANDARDS The Agency bases numerical treatment standards for regulated con- stituents on the performance of well-designed and well-operated BOAT treatment systems. These standards must account for analytical limitations in available treatment performance data, and the data must be adjusted for variabilities related to treatment, sampling, and analytical techniques and procedures. The purpose of this section is to calculate proposed treatment standards for K026 nonwastewaters and wastewaters for the constituent selected for proposed regulation using the available treatment performance data from the treatment technology identified as BOAT. H Proposed BDAT treatment standards for, K026 nonwastewaters and wastewaters are based on the demonstrated technology of incineration. Before treatment standards are calculated, the treatment performance data are corrected to account for analytical interferences associated with the chemical matrices of the samples. A complete discussion of the accuracy correction of treatment data is provided in Appendix A. Appendix A also contains the matrix spike recoveries and accuracy correction factors used to correct the treatment performance data, as weHrag,.the corrected treatment performance data. After treatment performance data are corrected for accuracy, the arithmetic average of the corrected data is calculated for each regulated 7-1 ------- constituent. In cases where the constituent is not detected in the treatment residual at or above its detection limit, the detection limit is used to calculate the average constituent concentration in the treated waste. Tables 7-1 and 7-2 at the end of this section present the averages of the corrected treatment performance data for the constituent proposed for regulation in K026 nonwastewaters and wastewaters, respectively. The next step in calculating treatment standards is to determine the variability factor (VF) for each regulated constituent. The variability factor accounts for the variability inherent in treatment system performance, treatment residual collection, and treatment sample analysis. (For more information on calculation of variability factors, see -EPA's Methodology for Developing BOAT Treatment Standards (Reference 1).) Variability factors for the constituent proposed for"regulation in K026 are shown in Tables 7-1 and 7-2. Finally, the treatment standard is calculated for each constituent proposed for regulation by multiplying the average of the correct treatment performance values by the variability factor for the constituent. Proposed treatment standards for nonwastewater and wastewater forms of K026 are pre- sented in Tables 7-1 and 7-2 and are discussed in greater-1deftail in the following sections. 7-2 ------- 7.1 Calculation of the Proposed Treatment Standard for K026 Nonwaste- waters Treatment performance data for the ash from rotary kiln incineration of K026 are not available. Therefore, the Agency is transferring performance data from treatment of organic constituents in RCRA Blend waste to develop treatment standards for organic constituents in nonwastewater forms of K026. The rationale for this transfer is presented in Section 4.0 of this document. Incineration generally results in the generation of ash (a nonwaste- water) and combustion gas scrubber water (a wastewater). The best measure of . performance for a destruction technology, such as incineration, is the total amount of each constituent of concern remaining after treatment. .„. Therefore, the proposed BOAT treatment standard for pyridine in K026 nonwastewaters was calculated based on total constituent concentration data transferred from the ash residual from incineration of RCRA Blend waste (Reference 7). The proposed treatment standard for pyridine in K026 nonwastewaters was calculated using six sample sets of data for rotary kiln incineration of RCRA Blend waste (Reference 7). Tables 4-2 and 4-3 of this document present the total concentrations of each organic constituent detected in untreated RCRA Blend waste and the treated nonwastewater residual (ash). Because pyridine was not detected in the untreated RCRA Blend waste, treatment perfor- mance data for pyridine in K026 nonwastewaters were transferred from nitro- benzene in RCRA Blend waste, as explained below. 7-3 ------- The particular constituent from which data are transferred is determined based on the characteristics of the waste that affect treatment performance by incineration with respect to the nonwastewater residual (i.e., incinerator ash) and the structural similarities between the constituents from and to which data are transferred. In the rotary kiln, energy in the form of heat is transferred to the waste to volatilize the organic waste constituents. To determine whether one constituent is volatilized similarly to another constituent, the Agency examines the boiling points and the structural simi- larities of the constituents. In general, the Agency believes that a constituent with a higher boiling point (bp) is more difficult to treat than a constituent with a lower boiling point. Whenever possible, treatment performance data are transferred from constituents detected in the untreated waste that have equal or higher boiling points. For K026 nonwastewaters, treatment performance data were transferred from nitrobenzene to pyridine, since nitrobenzene was detected in the untreated waste and has a higher boiling point than pyridine. The calculation calculation of the proposed treatment standard for pyridine in K026 nonwastewaters is shown in Table 7-1. 7.2 Calculation of the Proposed Treatment Standard for K026 Wastewaters Treatment performance data for the scrubber water from rotary kiln incineration of K026 are not available. Therefore, the Agency is transferring performance data from treatment of organic constituents in RCRA Blend waste to 7-4 ------- develop treatment standards for organic constituents in wastewater forms of K026. The rationale for this transfer is presented in Section 4.0 of this document. Incineration generally results in the generation of ash (a nonwaste- water) and combustion gas scrubber water (a wastewater). The best measure of performance for a destruction technology, such as incineration, is the total amount of each constituent of concern remaining after treatment. Therefore, the proposed BOAT treatment standard for pyridine in K026 wastewaters was calculated based on total constituent concentration data transferred from the scrubber water residual from incineration of RCRA Blend waste (Reference 7). The proposed treatment standard for pyridine in K026 wastewaters was calculated using six sample sets of data from rotary kiln incineration of RCRA Blend waste. Tables 4-2 and 4-4 of this document present the total concentra- tions of each organic constituent detected in the untreated RCRA Blend waste and the treated wastewater residual (scrubber water). Because pyridine was not detected in the untreated RCRA Blend waste, treatment performance data for pyridine in K026 wastewaters were transferred from nitrobenzene in RCRA Blend waste, as explained below. The particular constituent from which data are transferred is determined based on the characteristics of the waste that affect treatment performance of incineration with respect to the wastewater residual (i.e., scrubber water) and the structural similarities between the constituents from and to which data are transferred. In the secondary chamber (or afterburner), 7-5 ------- energy in the form of heat is added to destabilize chemical bonds to initiate the combustion reactions. To determine whether one constituent is destabi- lized similarly to another constituent, the Agency examines the bond dissocia- tion energies and the structural similarities of the constituents. In general, the Agency believes that a constituent with a higher bond dissociation energy (BDE) is more difficult to treat than a constituent with a lower BDE. Whenever possible, treatment performance data are trans- ferred from constituents detected in the untreated waste that have equal or higher BDEs. For K026 wastewaters, treatment performance data were trans- ferred from nitrobenzene to pyridine, since nitrobenzene was detected in the untreated waste and has a higher bond dissociation energy than pyridine. The calculation of the proposed treatment standard for pyridine in K026 wastewaters is shown in Table 7-2. 7-6 ------- Table 7-1 CALCULATION OF TREATMENT STANDARDS FOR CONSTITUENTS PROPOSED FOR REGULATION IN K026 NONWASTEUATERS Constituent from Which Arithmetic Average Treatment Performance of Corrected Treatment Standard BOAT List Constituent Data in RCRA Blend Waste Treatment Perfor- Variability (Average x VF) Proposed for Regulation Were Transferred mance Values (ppm) Factor (VF) (ppm) 39.

Generally, treatment performance data were corrected for accuracy as follows: (1) a matrix spike recovery was determined for each BOAT List constituent detected in the untreated or treated waste; (2) an accuracy correction factor was determined for each of the above constituents by dividing 100 by the matrix spike recovery (percent) for that constituent; and (3) treatment performance data for each BOAT List constituent detected in the untreated-or treated waste were corrected by multiplying the reported concentration of; -each constituent by its corresponding accuracy correction factor. The procedure for accuracy correction of the data is described in further detail below. Matrix spike recoveries are developed by analyzing a sample of a treated waste for a constituent and then re-analyzing the sample after the addition of-a known amount Io£iathe same constituent (i.e., spike) to the sample. The matrix spike recovery represents the total amount of constituent recovered after spiking, minus the initial concentration of the constituent in the sample, and the result divided by the spike concentration of the constitu- ent. A-2 ------- Matrix spike recoveries used to adjust the treatment performance data transferred to K026 are shown in Tables A-l and A-2. Duplicate matrix spikes were performed for some BOAT List constituents. If a duplicate matrix spike was performed for a constituent, the matrix spike recovery used for that constituent was the lower of the two values from the first matrix spike and the duplicate spike. An accuracy correction factor of 1 was used when matrix spike and duplicate matrix spike recoveries both exceeded 100%, so that the data were not adjusted to concentrations below the detection limits. Where a matrix spike was not performed for an organic constituent (as is the case with nitrobenzene in RCRA Blend waste), the matrix spike recovery for that constituent was derived from the average matrix spike recoveries of the appropriate group of constituents (e.g., semivolatile organics) for which recovery data were available. In this case, the matrix spike recoveries for all semivolatiles from the first matrix spike were averaged. Similarly, an average matrix spike recovery was calculated for the duplicate matrix spike recoveries. The lower of the two average matrix spike recoveries of the semivolatile organics group was used for any semivolatile constituents of interest for which no matrix spike was performed, in this case, nitrobenzene. The lower average recovery for kiln ash residuals was 100%, and that for scrubber water residuals was 84%. The accuracy correction factors used to calculate the proposed K026 treatment standards are 1.00 for nonwastewater and 1.19 for wastewater. The A-3 ------- corrected treatment concentrations for nitrobenzene in RCRA Blend waste nonwastewaters and wastewaters are presented in Table A-3.
