EPA is approving the delisting petition submitted by Eastman to have three waste streams generated from its rotary kiln incinerator (RKI) excluded, or delisted, from the definition of a hazardous waste. These waste streams are the rotary kiln incinerator (RKI) bottom ash, RKI fly ash, and RKI scrubber water blowdown. The RKI bottom ash and the RKI fly ash are derived from the management of several F-, K-, and U-waste codes. These waste codes are F001, F002, F003, F005, F039, K009, K010, U001, U002, U031, U069, U107, U112, U117, U140, U147, U161, U213, and U359. The Scrubber water blowdown produced by the RKI's air pollution control equipment is also derived from the management of several F-, K-, and U-waste codes as well as certain characteristic hazardous wastes. These waste codes are D001, D002, D003, D007, D008, D018, D022, F001, F002, F003, F005, F039, K009, K010, U001, U002, U031, U069, U107, U112, U117, U140, U147, U161, U213, and U359. The RKI is authorized to manage a list of additional F-, K-, U-, and P-codes to cover off-site sources not attributed to the above waste codes. If these waste codes are not specifically listed in the delisting exclusion, they are not covered by the exclusion and can not be managed as non-hazardous, unless and until, the exclusion is modified to include them.
Eastman's petition requests a delisting for three waste streams: The RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown listed as D001, D002, D003, D007, D008, D018, D022, F001, F002, F003, F005, F039, K009, K010, U001, U002, U031, U069, U107, U112, U117, U140, U147, U161, U213, and U359. Eastman does not believe that the petitioned wastes meet the criteria for which EPA listed them. Eastman also believes no additional constituents or factors could cause the wastes to be hazardous. EPA's review of this petition included consideration of the original listing criteria, and the additional factors required by the Hazardous and Solid Waste Amendments of 1984 (HSWA). See section 3001(f) of RCRA, 42 U.S.C. 6921(f), and 40 CFR 260.22 (d)(1)-(4). In making the initial delisting determination, EPA evaluated the petitioned waste against the listing criteria and factors cited in § 261.11(a)(2) and (a)(3). Based on this review, EPA agrees with the petitioner that the waste is non-hazardous with respect to the original listing criteria. If EPA had found, based on this review, that the waste remained hazardous based on the factors for which the waste was originally listed, EPA would have proposed to deny the petition. EPA evaluated the waste with respect to other factors or criteria to assess whether there is a reasonable basis to believe that such additional factors could cause the waste to be hazardous. EPA considered whether the waste is acutely toxic, the concentration of the constituents in the waste, their tendency to migrate and to bioaccumulate, their persistence in the environment once released from the waste, plausible and specific types of management of the petitioned waste, the quantities of waste generated, and waste variability. EPA believes that the petitioned wastes do not meet the listing criteria and thus should not be a listed waste. EPA's decision to delist the wastes identified above from the facility is based on the information submitted in support of this rule, including descriptions of the waste and analytical data from the Eastman, Longview, Texas facility.
Eastman will dispose of the fly ash and bottom ash in an onsite landfill. The scrubber water blowdown will be managed in the waste water treatment plant (WWTP). The sludge from the WWTP has been delisted. See Appendix IX to Part 261, Table 1. All management occurs on-site and will remain the same after the delisting is granted.
EPA published an amended list of hazardous wastes from nonspecific and specific sources on January 16, 1981, as part of its final and interim final regulations implementing section 3001 of RCRA. EPA has amended the lists several times and codified them in §§ 261.31 and 261.32. EPA lists these wastes as hazardous because: (1) They Start Printed Page 58317typically and frequently exhibit one or more of the characteristics of hazardous wastes identified in Subpart C of Part 261 (that is, ignitability, corrosivity, reactivity, and toxicity) or (2) they meet the criteria for listing contained in § 261.11(a)(2) or (a)(3).
Eastman manufactures a variety of chemicals and plastics at its facility located in Longview, Texas. The Longview, Texas facility occupies roughly 6,000 acres of land and produces approximately 40 chemical and plastic product lines. While Eastman owns and operates a majority of individual production plants at the facility, there are some production plants that are not owned by Eastman but are located on the facility. Eastman provides utility support to these captured facilities, such use of the wastewater treatment plant and waste management in the RKI through service agreements. The production processes employed by the captured facilities produce products in conjunction with Eastman. The Eastman-Longview Texas facility also accepts waste for processing in the RKI from other off-site Eastman facilities. This facility does not accept wastes from sources outside the Eastman family. The unit is dedicated to wastes similar to those generated by Eastman only facilities.
The RKI is a thermal combustion unit owned and operated by Eastman that is used for the destruction of hazardous and non-hazardous wastes generated by Eastman Chemicals as well as its captured facilities. The RKI operates at 1700-2200 °F and is RCRA permitted to manage a large variety of wastes including wastes generated from other Eastman divisions. These wastes can have a variety of D-, F-, U-, K-, and P- codes. In practice, the waste codes managed in the RKI will be associated with production processes from Eastman Chemicals.
The RKI Bottom and Fly Ashes and Scrubber Water Blowdown are generated by the RKI as residuals from the waste combustion process. Bottom ash is generated when large particulate matter drops from the secondary combustion chamber (SCC) into an ash removal pit situated directly under the SCC. Bottom ashes are removed from the pit via a chain driven ash conveyor system and placed in large containers for subsequent management. They are tested, may have polymers added to them for stabilization and disposed of in an on-site hazardous waste landfill. Fly ash is lighter than bottom ash and is associated with finer particulate matter that leaves the SCC as part of the “exhaust” gas. From the SCC, exhaust gases pass through a rapid quench tank and condenser, which have water layers to capture smaller particulate matter. Exhaust gas then proceeds through a wet scrubber where more particulate matter is removed. The “blowdown” water streams through the quench/condenser and scrubber systems are routed to a blowdown tank (clarifier). In the tank, the combined blowdown stream (fly ash and water) is phase separated with the scrubber water blowdown then going to the wastewater system and fly ash slurry going to a rotary filter for dewatering. It is at this point in the system that scrubber water blowdown is defined. It is also at this point in the system that dewatered Start Printed Page 58318solids from the rotary filter are considered fly ash. The dewatered fly ash is removed from the filter and placed in large containers for subsequent management which can consist of testing, addition of polymers (as needed), and disposal in the on-site hazardous waste landfill.

4. Description of the operations and waste received of the RKI.
EPA believes that the descriptions of Eastman's waste, and the analytical data submitted in support of the petition show that the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown are non-hazardous. Analytical data from Eastman's RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown samples were used in the Delisting Risk Assessment Software (DRAS). The data summaries for detected constituents are presented in Table 3, 4, and 5. EPA has reviewed the sampling procedures used by Eastman and has determined that they satisfy EPA's criteria for collecting representative samples of the variations in constituent concentrations in the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown. The data submitted in support of the petition show that constituents in Eastman's wastes are presently below health-based risk levels used in the delisting decision-making. EPA believes that Eastman has successfully demonstrated that the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown are non-hazardous.

The worst case scenario for management of the RKI bottom ash and RKI fly ash was modeled for disposal in a landfill. The worst case scenario for management of the RKI scrubber water blowdown was modeled for disposal in a surface impoundent. EPA used such information gathered to identify plausible exposure routes (i.e., ground water, surface water, soil, air) for hazardous constituents present in the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown. EPA determined that disposal in a Subtitle D landfill is the most reasonable, worst-case disposal scenario for Eastman's RKI bottom ash and RKI fly ash. EPA determined that disposal in a surface impoundment is the most reasonable, worst-case disposal scenario for Eastman's RKI scrubber water blowdown. EPA applied the DRAS described in 65 FR 58015 (September 27, 2000), 65 FR 75637 (December 4, 2000) and 73 FR 28768 (May 19, 2008), to predict the maximum allowable concentrations of hazardous constituents that may be released from the petitioned wastes after disposal and determined the potential impact of the disposal of Eastman's petitioned wastes on human health and the environment. In assessing potential risks to ground water, EPA used the maximum estimated waste volumes and the maximum reported extract concentrations as inputs to the DRAS program to estimate the constituent concentrations in the ground water at a hypothetical receptor well down gradient from the disposal site. Using the risk level (carcinogenic risk of 10-5 and non-cancer hazard index of 0.1), the DRAS program can back-calculate the acceptable receptor well concentrations (referred to as compliance-point concentrations) using standard risk assessment algorithms and Agency health-based numbers. Using the maximum compliance-point concentrations and EPA Composite Model for Leachate Migration with Transformation Products (EPACMTP) fate and transport modeling factors, the DRAS further back-calculates the maximum permissible waste constituent concentrations not expected to exceed the compliance-point concentrations in ground water.
EPA believes that the EPACMTP fate and transport model represents a reasonable worst-case scenario for possible ground water contamination resulting from disposal of the petitioned waste in a landfill for the ashes, and a surface impoundment for the liquid scrubber water blowdown. A reasonable worst-case scenario is appropriate when evaluating whether a waste should be relieved of the protective management constraints of RCRA Subtitle C. The use of some reasonable worst-case scenarios resulted in conservative values for the compliance-point concentrations and ensured that the waste, once removed from hazardous waste regulation, will not pose a significant threat to human health and/or the environment. The DRAS also uses the maximum estimated waste volumes and the maximum reported total concentrations to predict possible risks associated with releases of waste constituents through surface pathways (e.g., volatilization or wind-blown particulate from the landfill). As in the above ground water analyses, the DRAS uses the risk level, the health-based data and standard risk assessment and exposure algorithms to predict maximum compliance-point concentrations of waste constituents at a hypothetical point of exposure. Using fate and transport equations, the DRAS uses the maximum compliance-point concentrations and back-calculates the maximum allowable waste constituent concentrations (or “delisting levels”).
In most cases, because a delisted waste is no longer subject to hazardous waste control, EPA is generally unable to predict, and does not presently control, how a petitioner will manage a waste after delisting. Therefore, EPA currently believes that it is inappropriate to consider extensive site-specific factors when applying the fate and transport model. EPA also considers the applicability of ground water monitoring data during the evaluation of delisting petitions. In this case, the ground water monitoring data was submitted in the previous petition and these wastes do not appear to be impacting the ground water of the landfill.Start Printed Page 58322
EPA believes that the descriptions of Eastman's RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown and analytical characterizations of these wastes illustrate the presence of toxic constituents at lower concentrations in these waste streams. Therefore, it is reasonable to conclude that the likelihood of migration of hazardous constituents from the petitioned waste will be substantially reduced so that short-term and long-term threats to human health and the environment are minimized.
The DRAS results, which calculated the maximum allowable concentration of chemical constituents in the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown are presented in Tables 3, 4, and 5. Based on the comparison of the DRAS results and maximum TCLP concentrations found in Tables 3, 4, and 5, the petitioned wastes should be delisted because no constituents of concern are likely to be present or formed as reaction products or by products in Eastman's wastes.
EPA concluded, after reviewing Eastman's processes that no other hazardous constituents of concern, other than those for which Eastman tested, are likely to be present or formed as reaction products or by-products in Eastman's wastes. In addition, on the basis of explanations and analytical data provided by Eastman, pursuant to § 260.22, EPA concludes that the petitioned wastes: RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown do not exhibit any of the characteristics of ignitability, corrosivity, reactivity, or toxicity. See §§ 261.21, 261.22, 261.23, and 261.24 respectively.
During the evaluation of this petition, in addition to the potential impacts to the ground water, EPA also considered the potential impact of the petitioned waste via non-ground water exposure routes (i.e., air emissions and surface runoff) for the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown. With regard to airborne dispersion in particular, EPA believes that exposure to airborne contaminants from the petitioned waste is unlikely. No appreciable air releases are likely from the RKI bottom ash and, RKI fly ash under any likely disposal conditions. EPA evaluated the potential hazards resulting from the unlikely scenario of airborne exposure to hazardous constituents released from the wastewater in an open landfill. The results of this worst-case analysis indicated that there is no substantial present or potential hazard to human health and the environment from airborne exposure to constituents from the RKI bottom ash and RKI fly ash. The RKI scrubber water blowdown was also evaluated for releases to the air from an impoundment and no substantial present or potential hazard was identified.
The descriptions by Eastman of the hazardous waste process and analytical characterization, with the proposed verification testing requirements (as discussed later in this notice), provide a reasonable basis for EPA to grant the petition. The data submitted in support of the petition show that constituents in the waste are below the maximum allowable concentrations (See Tables 3, 4, and 5). EPA believes that the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown generated by Eastman contains hazardous constituents at levels which will present minimal short-term and long-term threats from the petitioned wastes to human health and the environment.
Thus, EPA believes that it should grant to Eastman an exclusion from the list of hazardous wastes for the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown. EPA believes that the data submitted in support of the petition show the Eastman's RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown to be non-hazardous.
EPA has reviewed the sampling procedures used by Eastman and has determined they satisfy EPA's criteria for collecting representative samples of variable constituent concentrations in the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown. The data submitted in support of the petition show that constituents in Eastman's wastes are presently below the compliance-point concentrations used in the delisting decision-making process and would not pose a substantial hazard to the environment and the public. EPA believes that Eastman has successfully demonstrated that the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown are non-hazardous.
EPA, therefore, proposes to grant an exclusion to Eastman for the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown described in its December 2008 petition. EPA's decision to exclude these wastes is based on analysis performed on samples taken of the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown.
If EPA finalizes the proposed rule, EPA will no longer regulate 1,000 cubic yards/year of RKI bottom ash; 750 cubic yards/year of RKI fly ash, and 643,000 cubic yards/year (500,000 million gallons) of RKI scrubber water blowdown from Eastman's Longview facility under parts 262 through 268 and the permitting standards of part 270.
The petitioner, Eastman, must comply with the requirements in 40 CFR Part 261, Appendix IX, Tables 1, 2, and 3 as amended by this notice. The text below gives the rationale and details of those requirements.
This paragraph provides the levels of constituent concentrations for which Eastman RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown, below which these wastes would be considered non-hazardous.
EPA selected the set of inorganic and organic constituents specified in paragraph (1) and listed in 40 CFR part 261, appendix IX, tables 1, 2, or 3 based on information in the petition. EPA compiled the inorganic and organic constituents list from descriptions of the manufacturing process used by Eastman, previous test data provided for the waste, and the respective health-based levels used in delisting decision-making. These delisting levels correspond to the allowable levels measured in the leachable concentrations of the RKI bottom ash and RKI fly ash, and total concentrations of the RKI scrubber water blowdown.
Waste classification as non-hazardous cannot begin until compliance with the limits set in paragraph (1) has occurred for four consecutive quarterly sampling events. For example, if Eastman is issued a final exclusion in August, the first of four quarterly samples per waste stream can be collected in September. If EPA deems that the four representative composite samples of each waste stream meet all the indicator constituent delisting limits, classification of the waste as non-hazardous can begin in September of the next year. If constituent levels in any annual sample (and retest, if applicable) taken by Eastman exceed any of the delisting levels set in paragraph (1), Eastman must: (i) notify EPA in accordance with paragraph (6), and; (ii) manage and dispose of the RKI bottom ash, RKI fly Start Printed Page 58323ash, and RKI scrubber water blowdown as hazardous waste generated under Subtitle C of RCRA.
Eastman must complete a verification testing program on the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown to assure that the wastes do not exceed the maximum levels specified in paragraph (1). If EPA determines that the data collected under this paragraph does not support the data provided in the petition, the exclusion will not cover the tested waste. This verification program operates on two levels.
The initial part of the verification testing program consists of testing four composite samples from four consecutive quarters of RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown for specified indicator parameters as described in paragraph (1). Levels of constituents measured in the samples of the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown that do not exceed the levels set forth in paragraph (1) can be considered non-hazardous after all four sets of sampling data meet the levels listed in paragraph (1).
The second part of the verification testing program is the annual testing of a representative composite sample of the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown for all constituents specified in paragraph (1). If any delisting levels are not met in an annual test sample, then a second composite sample shall be collected within 10 days of becoming aware of the failure, and it must be analyzed expeditiously for the TCLP constituent(s) that exceeded Delisting Levels.
If the annual testing of the wastes, and the retest, do not meet the delisting levels in paragraph (1), Eastman must notify EPA according to the requirements in paragraph (6). EPA will then take the appropriate actions necessary to protect human health and the environment as described in paragraph (6). Eastman must provide sampling results that support the rationale that the delisting exclusion should not be withdrawn.
The final exclusion is effective upon publication in the Federal Register but the change in waste classification as “non-hazardous” cannot begin until the four quarterly initial verification samples comply with the levels specified in paragraph (1). The waste classification as “non-hazardous” is also not authorized, if Eastman fails to perform the testing as specified herein. Should Eastman conduct the yearly testing as specified herein, then disposal of RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown as delisted waste may not occur in the following year(s) until Eastman obtains the written approval of EPA.
Paragraph (4) would allow Eastman the flexibility of modifying its processes (for example, changes in equipment or change in operating conditions) to improve its treatment processes. However, Eastman must prove the effectiveness of the modified process and request approval from EPA. Eastman must manage wastes generated during the new process demonstration as hazardous waste through verification sampling within 30 days of start-up.
To provide appropriate documentation that the Eastman facility is correctly managing the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown, Eastman must compile, summarize, and keep delisting records on-site for a minimum of five years. Eastman must keep all analytical data obtained pursuant to paragraph (3), including quality control information, for five years. Paragraph (5) requires that Eastman furnish these data upon request for inspection by any employee or representative of EPA or the State of Texas.
If the exclusion is made final, then it will apply only to 1,000 cubic yards/year of RKI bottom ash; 750 cubic yards/year of RKI fly ash, and 643,000 cubic yards/year (500,000 million gallons) of RKI scrubber water blowdown generated at the Eastman facility after successful initial verification testing.
EPA would require Eastman to submit additional verification data under any of the following circumstances:
(a) If Eastman significantly alters the waste treatment system except as described in paragraph (4).
(b) If Eastman uses any new manufacturing or production process(es), or significantly changes the current process(es) described in its petition; or
(c) If Eastman makes any changes that could significantly affect the composition or type of waste generated.
Eastman must submit a modification to the petition complete with full sampling and analysis for circumstances where the waste volume changes and/or additional waste codes are added to the waste stream. EPA will publish an amendment to the exclusion, if the changes are acceptable.
Eastman must manage waste volumes greater than 1,000 cubic yards/year of RKI bottom ash; 750 cubic yards/year of RKI fly ash and 643,000 cubic yards/year (500,000 million gallons) of RKI scrubber water blowdown as hazardous waste until EPA grants a revised exclusion. When this exclusion becomes final, the management by Eastman of the RKI bottom ash, RKI fly ash, and RKI scrubber water blowdown covered in this petition would be relieved from Subtitle C jurisdiction. Eastman may not classify the waste as non-hazardous until the revised exclusion is finalized.
The purpose of paragraph (6) is to require Eastman to disclose new or different information related to a condition at the facility or disposal of the waste, if it is pertinent to the delisting. Eastman must also use this procedure if the waste sample (and retest, if applicable) in the annual testing fails to meet the levels found in paragraph (1). This provision will allow EPA to reevaluate the exclusion, if a source provides new or additional information to EPA. EPA will evaluate the information on which it based the decision to see if it is still correct or if circumstances have changed so that the information is no longer correct or would cause EPA to deny the petition, if presented.
This provision expressly requires Eastman to report differing site conditions or assumptions used in the petition in addition to failure to meet the annual testing conditions within 10 days of discovery. If EPA discovers such information itself or from a third party, it can act on it as appropriate. The language being proposed is similar to those provisions found in RCRA regulations governing no-migration petitions at § 268.6.
EPA believes a clear statement of its authority in delisting is merited in light of EPA's experience. See the Federal Register notice regarding Reynolds Metals Company at 62 FR 37694 (July 14, 1997) and 62 FR 63458 (December 1, 1997) where the delisted waste leached at greater concentrations into the environment than the concentrations predicted when conducting the TCLP, leading EPA to repeal the delisting. If an immediate threat to human health and the environment presents itself, EPA will continue to address these situations on Start Printed Page 58324a case-by-case basis. Where necessary, EPA will make a good cause finding to justify emergency rulemaking. See APA section 553(b)(3)(B).
If Eastman violates the terms and conditions established in the exclusion, EPA will start procedures to withdraw the exclusion. Where there is an immediate threat to human health and the environment, EPA will evaluate the need for enforcement activities on a case-by-case basis. EPA expects Eastman to conduct the appropriate waste analysis and comply with the criteria explained above in paragraph (1) of the exclusion.
