ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: EPA is promulgating amendments to the air emission standards for existing and new large municipal waste combustor (MWC) units. Standards for MWC units were promulgated in 1995 and implemented in 2000. The Clean Air Act (CAA) requires review of these standards every 5 years. The review is to be conducted in accordance with CAA section 129 and section 111 requirements, with standards revised as necessary. For existing MWC units, the goal of this action is to amend the standards to reflect the actual performance levels being achieved by existing MWC units. For new MWC units, the goal of this action is to amend the standards to reflect the performance level achievable by MWC units constructed in the future. Other technical improvements are also being made to the standards for MWC units. DATES: Effective Dates: The amendment to Sec. 60.50 is effective May 10, 2006. The final rule amendments to the standards for new sources in subpart Eb of 40 CFR part 60 (Sec. Sec. 60.50b, 60.51b, 60.52b, 60.53b, 60.54b, 60.57b, 60.58b, 60.59b) are effective November 6, 2006. The final rule amendments to the emission guidelines for existing sources in subpart Cb of 40 CFR part 60 (Sec. Sec. 60.30b, 60.31b, 60.32b, 60.33b, 60.34b, Tables 1, 2, and 3 to subpart Cb) are effective July 10, 2006. ADDRESSES: Docket.

Background Information Section 129 of the CAA, entitled ``Solid Waste Combustion,'' requires EPA to develop and adopt NSPS and emission guidelines for solid waste incineration units pursuant to CAA sections 111 and 129. Section 111(b) of the CAA (NSPS program) addresses emissions from new MWC units and section 111(d) of the CAA (emission guidelines program) addresses emissions from existing MWC units. The NSPS are directly enforceable Federal regulations. The emission guidelines are not directly enforceable but, rather, are implemented by State air pollution control agencies through sections 111(d)/129 State plans. In December 1995, EPA adopted NSPS (subpart Eb of 40 CFR part 60) and emission guidelines (subpart Cb of 40 CFR part 60) for MWC units with a combustion capacity greater than 250 tons per day. These MWC units are referred to as large MWC units. Both the NSPS and emission guidelines require compliance with emission limitations that reflect the performance of maximum achievable control technology (MACT). The NSPS apply to new MWC units after the effective date of the NSPS or at start-up, whichever is later. The emission guidelines apply to existing MWC units built before the NSPS applicability date and required compliance by December 2000. These retrofits were completed on time, and the controls installed to meet the required emission limitations were highly effective in reducing emissions of all of the CAA section 129 pollutants emitted by large MWC units. Section 129(a)(5) of the CAA requires EPA to conduct a 5-year review of the NSPS and emissions guidelines and, if appropriate, revise the NSPS and emission guidelines. The EPA has completed that review. On December 19, 2005 (70 FR 75348), EPA proposed amendments to the NSPS and emission guidelines to reflect the revisions EPA believes are appropriate. EPA carefully considered comments received on the proposal, and this action promulgates those revisions. II. Summary of Amendments A. What are the major revisions resulting from the review? Two major revisions result from EPA's review: Revisions to the emission limits and revisions to compliance testing provisions. Relative to the 1995 emission guidelines for existing MWC units, the emission limits are revised for dioxin, cadmium, lead, mercury, and particulate matter. The nitrogen oxides emission limit for mass burn rotary waterwall type MWC units is also revised. Relative to the 1995 NSPS for new MWC units, the emission limits are revised for cadmium, lead, mercury, and particulate matter. For both the emission guidelines and NSPS, the compliance testing provisions have been revised to require increased data availability from continuous emissions monitoring systems (CEMS). The revisions require CEMS to generate at least 95 percent data availability on a calendar year basis and at least 90 percent data availability on a calendar quarter basis. The emission guidelines and NSPS have also been revised to allow the optional use of CEMS to monitor particulate matter and mercury. B. What are the revised emission limits? The final amendments revise many of the emission limits in both the NSPS and emission guidelines. Relative to the NSPS, the most significant revisions are in the cadmium and mercury emission limits. Relative to the emission guidelines, the most significant revisions are in the dioxin/furan (for units equipped with electrostatic precipitators (ESPs)) and mercury emission limits, as well as nitrogen oxides for mass burn rotary combustors. Table 1 of this preamble contains a summary of the final emission limits.

C. Are other amendments being promulgated? The final amendments also make the following changes based on information received during implementation of the MWC emission guidelines and apply equally to the NSPS and emission guidelines, unless otherwise specified. Following is a list of the most significant changes compared to the 1995 NSPS and emission guidelines. Operating PracticesThe final amendments revise the operator stand-in provisions in Sec. 60.54b(c) to clarify how long a shift supervisor is allowed to be off site when a provisionally certified control room operator is standing in. A provisionally certified control room operator may stand in for up to 12 hours without notifying EPA; for up to 2 weeks if EPA is notified; and longer than 2 weeks if EPA is notified and the MWC owner demonstrates to EPA that a good faith effort is being made to ensure that a certified chief facility operator or certified shift supervisor is on site as soon as practicable. In the final amendments, a provisionally certified operator who is newly promoted or recently transferred to a shift supervisor position or chief facility operator position is able to serve up to 6 months without notification before taking the American Society of Mechanical Engineer's (ASME) Standard for the Qualification and Certification of Resource Recovery Facility Operators (QRO) certification exam for full certification. The final amendments add two additional classifications of MWC units to the emission guidelines and add associated carbon monoxide limits to assure good combustion practices. The two new classifications are ``spreader stoker fixed floor refuse-derived fuel (RDF)-fired/100 percent coal capable combustor'' and ``semi-suspension RDF-fired combustor/wet RDF process conversion.'' Operating Parameters The final amendments revise Sec. 60.58b(m) to establish an 8-hour block average for measuring activated carbon injection (ACI) rate. This makes the NSPS and emission guidelines for large MWC units consistent with the newer (year 2000) CAA section 129 regulations for small MWC units (40 CFR part 60, subparts AAAA and BBBB), which monitor ACI rate using an 8-hour block average. Performance Testing and Monitoring The final amendments revise the annual mercury testing requirements to additionally allow for optimization of mercury control operating parameters by waiving operating parameter limits during the mercury performance test and during the 2 weeks preceding the mercury performance test. This is already done for dioxin testing. It is recommended that both dioxin and mercury testing be done during optimization testing. The final amendments revise the relative accuracy criterion for sulfur dioxide and carbon monoxide CEMS. The final amendments add flexibility to the annual compliance testing schedule so that a facility tests once per calendar year, but no less than 9 months and no more than 15 months since the previous test. The revision provides flexibility to facilities when facing scheduled and unscheduled outages, adverse local weather conditions, and other conditions, while still meeting the intent of the compliance testing. The final amendments also require at least five compliance tests be completed in each 5-year calendar period. The final amendments allow the use of parametric monitoring limits from an exceptionally well-operated MWC unit (i.e., MWC unit with dioxin emissions for 2 years in a row below 15 nanogram/ dry standard cubic meter (ng/dscm) for existing MWC units and below 7 ng/dscm for new MWC units) be applied to all identical units at the same plant site without retesting for dioxin. The final amendments revise the particulate matter and mercury compliance testing requirements to allow the optional use of a particulate matter CEMS or mercury CEMS in place of stack testing and would allow the optional use of multi-metal, hydrogen chloride, dioxin/ furan CEMS in place of stack tests after which performance specifications for these CEMS are promulgated. The final amendments add provisions for monitoring the activated carbon injection pressure or equivalent parameter. The final amendments revise the data availability requirement for CEMS. Data must be available for at least 90 percent of the hours of operation per calendar quarter and at least 95 percent of the hours of operation per calendar year. The final amendments clarify the exclusion of monitoring data from compliance calculations during periods of startup, shutdown, or malfunctions, but requires identification of such periods and an explanation for exclusion of such data. Other Amendments The final amendments clarify the meaning of the term ``Administrator'' in the standards. D. Is an implementation schedule being promulgated? Yes. Under the emission guidelines, and consistent with CAA section 129, revised State plans containing the revised emission limits and other [[Page 27327]] requirements in the revised emission guidelines are due within 1 year after promulgation of these revisions. That is, revised State plans must be submitted to EPA by May 10, 2007. The emission guidelines then allow MWC units two compliance schedules. As a first option, MWC units have up to 2 years from the date of EPA approval of a State plan to comply. Consistent with CAA section 129, EPA expects States to require compliance as expeditiously as practicable. Large MWC units have already installed the emission control equipment necessary to meet the revised limits, and EPA, therefore, anticipates that most State plans will include compliance dates less than 2 years following approval of State plans. In most cases, the only changes necessary are to review the revisions and adjust the emission monitoring and reporting accordingly. State plan revisions are not approvable until the related State rule or enforceable mechanism is adopted and becomes effective. As a second compliance option, an owner or operator of an MWC unit that plans a substantial upgrade, can apply to the EPA Administrator (if the MWC is regulated by a Federal Section 111(d)/129 plan) or the State Administrator (if the MWC is regulated by an EPA approved State section 111(d)/129 plan), for a site-specific compliance schedule that can extend up to 5 years following publication of these amendments. In revising the emission limits in a State plan, a State has two options. First, it could insert the new emission limits in place of the current emission limits, follow procedures in 40 CFR part 60, subpart B, and submit a revised State plan to EPA for approval. If the revised State plan contains only the new emission limits (i.e., the existing emission limits are not retained), then the new emission limits must become effective immediately since the current limits would be removed from the State plan. A second approach would be for a State plan to include both the current and the new emission limits. This allows a phased approach in applying the new limits. That is, the State plan would make it clear that the existing emission limits remain in force and apply until the date the new emission limits are effective (as defined in the State plan). E. Has EPA revised the applicability date of the NSPS? No. The applicability date for the NSPS units remains September 20, 1994; however, units for which construction or modification is commenced after December 19, 2005, are subject to more stringent emission limits. Under the final amendments, units that commenced construction after September 20, 1994, and on or before December 19, 2005, continue to be subject to the NSPS emission limits that were promulgated in 1995 and that remain in the 40 CFR part 60, subpart Eb NSPS. Units that commence construction after December 19, 2005, are subject to the new NSPS limits being added to subpart Eb. The EPA is not aware of, and commenters did not identify, any MWC units that were modified or reconstructed after June 19, 1996 (effective date of the December 19, 1995 NSPS), therefore, EPA simplified the applicability text for the NSPS to be MWC units that commenced construction, modification, or reconstruction after September 20, 1994. The use of one date is the most understandable. As noted in adopting regulations for MWC in 1995, any change made to an MWC unit for the principal purpose of complying with the subpart Cb, 40 CFR part 60, emission guidelines or subpart Eb NSPS is not considered to be a modification or reconstruction. III. Responses to Significant Comments A. What areas of the proposal received the most comments? The comment letters received by EPA on the proposed rule, identified more than 50 issues for consideration. The most common issue was related to the statistical methods used by EPA to assist in development of the proposed emission limits. Associated comments included those on the adequacy of the database, appropriateness of the data screening procedures, and development of emissions variability factors. In addition, EPA received legal comments on recalculating the MACT floor. B. Why did EPA not recalculate the MACT floor? Section 129(a)(5) of the CAA requires EPA to ``* * * review, and in accordance with this section and section 111, revise'' performance standards and other requirements under section 129. The provision does not mandate that this review be conducted in a single, unvarying manner. One commenter, nevertheless, maintains that because of the reference to ``this section and section 111,'' EPA is necessarily required to repeat the CAA section 129(a) standards development process, which includes re-determining the MACT floor for new and existing MWC units. EPA does not read the provision as requiring another analysis of the MACT floor. A more natural reading of the provision is that EPA is to conduct a periodic review to determine whether advances in technology warrant revisions to the standards. This is the same general approach taken by EPA in reviewing CAA section 111 standards. There is nothing in the language of section 129(a)(5) that speaks directly to the issue of whether another floor analysis is required. EPA believes that a reasonable interpretation of the reference cited by the commenter leads to the conclusion that such an analysis is not required. EPA believes that a reasonable interpretation of the reference requires EPA to determine ``the degree of emission limitation achievable through application of the best system of emission reduction which (taking into account the cost of achieving such reduction and any non-air quality health and environmental impact and energy requirements) the Administrator determines has been adequately demonstrated.'' See, Clean Air Act section 111(a)(1). Recalculating the floor as advocated by the commenter would eviscerate the Administrator's ability to effectively consider factors that Congress has otherwise mandated be considered. That is, once a new floor has been calculated, the Administrator cannot establish emission limits which are less stringent than that floor even if consideration of costs and other factors would otherwise lead him to conclude that this is appropriate. EPA believes that Congress would have been explicit in its instructions had it intended this result. Since it was not, EPA believes that a reasonable interpretation of section 129(a)(5) is that it does not require EPA to recalculate the floor for existing units. EPA also believes that interpreting section 129(a)(5) as requiring additional floor determinations could effectively convert existing source standards into new source standards. After 5 years, all sources will be performing at least at the existing source MACT level of performance and some sources will be performing at the new source MACT level of performance. As a result, it is likely that the average performance of the best performing 12 percent of sources will be at or near the new source MACT level of performance. This would result in existing sources being subject to new source MACT requirements on a 5- year cycle regardless of whether those sources have undergone a change which would otherwise require compliance with that standard. EPA sees no indication that section 129(a)(5) was intended to have this inexorable downward ratcheting effect. Rather, we read the provision as [[Page 27328]] requiring EPA to consider developments in pollution control at the sources and to revise the standards based on it evaluation of the costs, non-air quality effects and energy implications of doing so. C. Relative to technical issues, how were the statistical methods used to develop emission limits? The statistical methods were used as an aid. One must remember that statistical methods attempt to estimate what could occur in the future based on what occurred in the past. Statistical methods provide an estimate of what could occur, but they are not the actual process. Actual events will determine what actually occurs. The usefulness of statistical methods is affected by the appropriateness of the model and assumptions used as well as the quality and size of the database. Statistical methods are a useful aid in making an informed decision but they alone cannot dictate a decision. Human judgment must always be applied in making the final decision. D. How were the final emission limits selected? The final emission limits were selected in a three-step process. The first step was to develop statistical estimates. The second step was to consider the statistical estimates in relation to current performance levels. The third step was for EPA to select emission limits. Relative to the first step, EPA identified an appropriate statistical model, defined reasonable assumptions, and applied the model to year 2000 compliance data for all MWC units with the relevant control technologies to estimate the peak emission rate that is estimated to occur from time to time, considering inherent variability in emission levels. Next, EPA obtained year 2000 to 2005 test data from more than a dozen MWC units. This data was compared to the statistical estimates and considered in relation to public comments. As a last step, EPA selected the emission limits for the final standards. E. What types of comments were received on the EPA statistical methods? A range of comments were received on the statistical methodology. Some commenters simply presented their own statistical methodology, which they claimed was more conventional or appropriate for the data analysis being conducted. They went on to claim their methodology would lead to more appropriate emission limits. The most common statistical methodology identified by commenters followed the approach presented by the Integrated Waste Services Association (IWSA). EPA concludes that the IWSA approach presents another generally acceptable methodology for developing emission limits. Based on public comments, EPA revised its methodology and updated the database and conducted another analysis. The revised methodology used by EPA followed that used by IWSA, but improved upon it with more accurate selection of frequency distributions on which to base the analyses. Regardless of the statistical methodology used, the results of the statistical analysis were used only as a tool to aid in selection of appropriate emission limits. That is, the estimates from the new statistical analysis were used as an aid in selecting the final emission limits. The new analysis is contained in the docket. F. What comments were received on the EPA database and data screening procedures? Although the MWC database is one of the larger databases EPA has had for standards development, a number of commenters indicated the database is inadequate because of its age. They indicated that the data from initial MACT compliance tests (year 2000) is old and should be supplemented with more current data. Some commenters suggested the more current data would address emission control performance over time including deterioration of the control system. (It could also be argued more current data could show improved performance as MWC operators became more familiar with operating an emission control system.) EPA believes the size of the year 2000 database adequate to address emission variability for developing estimates; however, EPA did collect 2000 to 2005 test data from more than a dozen MWC units to aid in reviewing emission control performance over time and to compare to the statistical estimates. Additionally, commenters identified a number of errors in the database. These were corrected by EPA. Relative to data screening as done by EPA at proposal, commenters claimed its use inappropriate and that it introduced bias to the results. At proposal, EPA had screened data to identify values that required additional investigation not because the values were high or low. Based on public comments, EPA dropped the data screening procedure in its final analysis. In some cases, using the unscreened data rather than the screened data changed estimates, but in other cases it did not. For example, the particulate matter emissions limit with or without data screening did not change. For cadmium, the change from data screening to non-screening changed the estimate by 1 micrograms/dry standard cubic meter ([mu]g/dscm) (31 [mu]g/dscm to 32 [mu]g/dscm). A more significant change resulting from changing from data screening to non- screening was in the estimate for the lead emission limit. EPA found that data received following proposal showed highly variable lead emissions. The statistical analysis data for lead used by EPA and IWSA was not as variable as data for subsequent years that were obtained after the statistical analyses were completed. Therefore, EPA discounted both the EPA and industry statistical estimates, and based the final limit on a review of the year 2000-2005 test data and public comment, selecting a higher emission limit. In selecting the final mercury emission limit, EPA again discounted both the EPA and industry statistical estimates, and based the final limit on a review of the year 2000-2005 test data and public comment, this time selecting a lower emission limit. The EPA and IWSA analyses used year 2000 test data, and both analyses supported retention of the existing mercury limit of 80 [mu]g/dscm. However, EPA obtained mercury test data for 68 different tests conducted on ESP-equipped MWC units in the 2000 to 2005 time period. These data showed that mercury emissions are considerably lower than suggested by the statistical analyses. To understand this performance, EPA reviewed uncontrolled mercury emissions data from a number of MWC units for the 1995 to 2005 time period. The data showed that in 1995, when the MACT standards were adopted, average uncontrolled mercury emission levels were about 250 [mu]g/dscm, and, by 2005, the level was reduced by about 50 percent to about 125 [mu]g/dscm. The result of application of 85 percent mercury control to these lower mercury inlet levels has resulted in much lower mercury outlet levels, as demonstrated by the test data. A 50 percent reduction in inlet mercury levels suggests an emission limit of 40 [mu]g/dscm in the MACT standards. Public comments and test data suggested that levels less than 30 [mu]g/dscm are being achieved. However, in consideration of the potential use of mercury CEMS and the higher mercury variability that may be observed with CEMS use, the final standards were set at 50 [mu]g/dscm for both existing and new MWC units. G. What was the most important factor affecting emissions estimates? The emission variability factor was the most important factor affecting emissions estimates. The emission [[Page 27329]] variability factor is an emission factor that is added to the mean performance level in order to estimate the peak emissions level that will occur from time to time. For example, over an extended period (many years) particulate matter emissions from an MWC could average 15 milligrams per dry standard cubic meter (mg/dscm). Clearly, individual particulate matter tests would be above and below 15 mg/dscm. The emission variability factor addresses how much individual test values are estimated to be above the 15 mg/dscm mean value. If the variability factor were 10 mg/dscm, it would mean that it is estimated that from time to time particulate matter emissions could be as high as 25 mg/ dscm (15 + 10 = 25). H. What emission variability factor is appropriate? Although most commenters and EPA used similar statistical methodology, differences were identified in assumptions used to develop emission variability factors. EPA used percentiles. The percentile addresses how often one would estimate that an emissions level may exceed a certain value (the standard). For analysis of CEMS data, such as sulfur dioxide or nitrogen oxides, where 365 tests (24-hr CEMS average) are conducted per year, EPA and commenters agreed the emission limit should be set at a level that would be expected to be exceeded only once per year at a well-operated MWC plant. Once per year translates into a 99.7 percentile level. A number of commenters suggested the use of a 99.7 percentile for development of limits using both CEMS data (sulfur dioxide and nitrogen oxide) and stack test data (cadmium, lead, mercury, particulate matter, dioxin, and hydrogen chloride). This is one area where EPA disagrees with these commenters. EPA concludes a different assumption is appropriate. For stack test emission limits, EPA used a different and lower percentile. This is the same approach EPA used at proposal. Analysis of data to estimate emission limits to be enforced by stack test methods must be done using a different approach than where enforcement is to be based on CEMS. Historically, for stack test data, EPA used its judgment to select appropriate emission limits in consideration of emissions variability over a wide range of operating conditions, and consideration of the limitations of compliance determination by infrequent stack testing. For this rulemaking, EPA moved a step forward using statistical methods to aid in estimating appropriate emission levels for stack test compliance. The percentile for estimating emission limits enforced by infrequent stack testing must also reflect a reasonable consideration of emissions variability and compliance limitations of stack testing. Based on EPA's experience, EPA concluded a 99 percentile was appropriate to estimate achievable emission levels for emission limits enforced by stack testing. Therefore, just as done in the December 19, 2005 proposal, EPA continues to use a 99 percentile for estimating emission limits to be enforced by stack testing and 99.7 percentile for estimating emission limits to be enforced by CEMS. The commenters did not provide any persuasive information for the use of a 99.7 percentile for both CEMS and stack test compliance methods. I. What other significant comments were received on the proposal, and how were they addressed in the final rule? Other significant comment topics included CEMS data availability and increased use of CEMS, including particulate matter CEMS and other new CEMS technology. The CEMS data availability issue and increased use of CEMS technology are discussed below. Other comments are addressed in the response to comment document, which is contained in the docket. J. What comments were received on the proposed 95 percent CEMS data availability requirement, and how were they addressed in the final rule? Most commenters agreed that 95 percent CEMS data availability was achievable by a single CEMS, but indicated that legally requiring demonstration of such high availability levels on a short term basis may result in the installation of a second backup CEMS to assure compliance. Commenters indicated that from time to time it is necessary to obtain replacement parts for CEMS, sometimes from foreign suppliers, and this can quickly deteriorate data availability levels on a short term basis. In proposing the 95 percent data availability requirement, it was not EPA's intention to require installation of a second backup CEMS. To address these concerns, the final rule addresses CEMS data availability in two steps. First, a 90 percent CEMS data availability requirement is applied on a calendar quarter basis. Second, a 95 percent data availability requirement is applied on a calendar year basis. The procedure for calculation of data availability is also revised in the final rule to be hours of valid CEMS data collected divided by the hours of MWC operation. This is done on a calendar quarter basis for the 90 percent requirement and on a calendar year basis for the 95 percent requirement. The current requirement of obtaining CEMS data for 75 percent of the operating hours per day before data is counted toward the CEMS data availability requirement has been removed from the MWC regulations to assure consistency with CEMS requirements for other source categories. K. What comments were received on the expanded use of CEMS technology, and how were the comments addressed in the final rule? In the proposal, EPA allowed the optional use of particulate matter CEMS and requested comment on the optional use of particulate matter CEMS, multi-metal CEMS, hydrogen chloride CEMS, and semi-continuous dioxin monitoring. Some commenters stated the CEMS have not been validated on MWC units; that PM CEMS have not been installed in any MWC in the United States; and the use of PM CEMS on MWCs in Europe are not indicative of the appropriateness of their use in the United States, because of differences in how CEMS are used for enforcement. While PM CEMS are used in the United States on other types of sources, there could be some operational differences between these sources and MWCs that affect the performance of PM CEMS on MWCs. In the final rule, EPA is allowing, as optional test methods, the use of particulate matter CEMS and mercury CEMS, since performance specifications are available for these CEMS. In the regulations, the owners or operators of an MWC would provide EPA a 30 day notice before starting to use the CEMS and provide a 30 day notice if they elect to discontinue the use of the CEMS. As an incentive for the optional application of CEMS in the MWC context, EPA is modifying the monitoring availability requirements. The 90 percent and 95 percent CEMS data availability requirements do not apply to particulate matter CEMS or mercury CEMS use for the first 2 years of application. For the other CEMS (multi-metal, hydrogen chloride, and semi-continuous dioxin monitoring), their optional use is allowed after their respective performance specifications are adopted by EPA. No dates for adoption are currently scheduled. L. Would the use of particulate matter CEMS or mercury CEMS for compliance testing require EPA to adopt alternative particulate matter and mercury emission limits? Theoretically, yes. The use of particulate matter CEMS or mercury [[Page 27330]] CEMS for compliance testing would theoretically require EPA to adopt alternative particulate matter and mercury emission limits. The move from once per year stack testing (where emission limits were calculated from the 99 percentile) to CEMS (99.7 percentile) suggests the emission limit should be increased if the same data averaging period is used. To address this, the final rule increases the data averaging period from 8 hours (typical particulate matter and mercury stack test period) to a 24-hr daily average if particulate matter or mercury CEMS are used. Past analysis of sulfur dioxide CEMS and nitrogen oxides CEMS data (and utility particulate matter CEMS data) indicate increasing the averaging period to a 24-hr daily average will reduce emissions variability and associated peak emissions estimates. EPA supports the optional use of particulate matter and mercury CEMS, but is fully aware that no particulate matter CEMS or mercury CEMS data from MWC units are available from domestic MWC units. EPA encourages MWC owners or operators who elect to apply particulate matter or mercury CEMS, to notify EPA as soon as data are collected to allow a determination if alternative emission limits are appropriate. IV. Impacts of the Final Amendments EPA projects the final amendments will have no additional impacts to air, water, or energy since the final emission limits can be achieved using the same air pollution control technology that was used to comply with the current emission limits. Similarly, EPA expects minimal cost and no economic impact for the same reason. Existing large MWC units will continue to use their existing MACT control technology to meet the emission limits, and will not incur costs to retrofit equipment. In addition, EPA does not believe that the revised limits will result in any increase in operating or maintenance costs. The same conclusions apply to new MWC units since EPA expects that new MWC units will be equipped with the same control technology used to comply with the 1995 NSPS. V. Statutory and Executive Order Reviews A. Executive Order 12866: Regulatory Planning and Review Under Executive Order 12866 (58 FR 51735, October 4, 1993), EPA must determine whether the regulatory action is ``significant'' and, therefore, subject to review by OMB and the requirements of the Executive Order. The Executive Order defines ``significant regulatory action'' as one that is likely to result in a rule that may: (1) Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or Tribal governments or communities; (2) Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency; (3) Materially alter the budgetary impact of entitlements, grants, user fees, or loan programs, or the rights and obligations of recipients thereof; or (4) Raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in the Executive Order. Pursuant to the terms of Executive Order 12866, OMB has notified EPA that it considers the final rule a ``significant regulatory action'' within the meaning of the Executive Order. EPA has submitted today's action to OMB for review. Changes made in response to OMB suggestions or recommendations will be documented in the public record. B. Paperwork Reduction Act The Office of Management and Budget previously approved the information collection requirements contained in the NSPS and emission guidelines for large MWC units under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq., at the time the NSPS and emission guidelines were promulgated on December 19, 1995 and subsequent recertifications. The information collection request has been assigned OMB Control Number 2060-0210 (EPA ICR No. 1506.10). The final amendments result in no changes to the information collection requirements of the NSPS or emission guidelines and will have no impact on the information collection estimate of project cost and hour burden made and approved by OMB. Therefore, the information collection requests have not been revised. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information. An Agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA's regulations are listed in 40 CFR part 9 and 40 CFR chapter 15. C. Regulatory Flexibility Act EPA has determined that it is not necessary to prepare a regulatory flexibility analysis in connection with the final rule. For purposes of assessing the impacts of the final rule on small entities, small entity is defined as follows: (1) A small business in the regulated industry that has gross annual revenues of less than $6 million; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; or (3) a small organization that is any not-for-profit enterprise that is independently owned and operated and is not dominant in its field. After considering the economic impacts of the final rule on small entities, EPA has concluded that today's action will not have a significant economic impact on a substantial number of small entities. The final rule will not impose any requirements on small entities. D. Unfunded Mandates Reform Act Title II of the Unfunded Mandates Reform Act (UMRA) of 1995, Public Law 104-4, establishes requirements for Federal agencies to assess the effects of their regulatory actions on State, local, and tribal governments and the private sector. Under section 202 of the UMRA, EPA generally must prepare a written statement, including a cost-benefit analysis, for proposed and final rules with ``Federal mandates'' that may result in expenditures by State, local, and tribal governments, in the aggregate, or by the private sector, of $100 million or more in any 1 year. Before promulgating an EPA rule for which a written statement is needed, section 205 of the UMRA generally requires EPA to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most cost-effective, or least burdensome alternative that achieves the objectives of the rule. The provisions of section 205 do not apply when they are inconsistent with applicable law. [[Page 27331]] Moreover, section 205 allows EPA to adopt an alternative other than the least costly, most cost-effective, or least burdensome alternative if the Administrator publishes with the final rule an explanation why that alternative was not adopted. Before EPA establishes any regulatory requirements that may significantly or uniquely affect small governments, including tribal governments, EPA must have developed a small government agency plan under section 203 of the UMRA. The plan must provide for notifying potentially affected small governments, enabling officials of affected small governments to have meaningful and timely input in the development of EPA's regulatory proposals with significant Federal intergovernmental mandates, and informing, educating, and advising small governments on compliance with the regulatory requirements. EPA has determined that the final rule does not contain a Federal mandate that may result in expenditures of $100 million or more for State, local, and tribal governments, in the aggregate, or the private sector in any 1 year because the final rule does not require a change in the control technology applied. Thus, the final rule is not subject to the requirements of section 202 and 205 of the UMRA. In addition, EPA has determined that the final rule contains no regulatory requirements that might significantly or uniquely affect small governments. Therefore, the final rule is not subject to the requirements of section 203 of the UMRA. E. Executive Order 13132: Federalism Executive Order 13132 (64 FR 43255, August 10, 1999), requires EPA to develop an accountable process to ensure ``meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.'' ``Policies that have federalism implications'' is defined in the Executive Order to include regulations that have ``substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.'' The final rule does not have federalism implications. It will not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. The final rule will not impose substantial direct compliance costs on State or local governments because the regulations will not require any change in the emission control technology currently used to comply with the 1995 NSPS and emissions guidelines, and will not preempt State law. Thus, Executive Order 13132 does not apply to the final amendments. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments Executive Order 13175, (65 FR 67249, November 9, 2000), requires EPA to develop an accountable process to ensure ``meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.'' The final rule does not have tribal implications, as specified in Executive Order 13175. They will not have substantial direct effects on tribal governments, on the relationship between the Federal government and Indian tribes, or on the distribution of power and responsibilities between the Federal government and Indian tribes, as specified in Executive Order 13175. EPA is not aware of any large MWC unit owned or operated by tribal government. Thus, Executive Order 13175 does not apply to the final rule. G. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks Executive Order 13045 (62 FR 19885, April 23, 1997), applies to any rule that: (1) Is determined to be ``economically significant'' as defined under Executive Order 12866, and (2) concerns an environmental health or safety risk that EPA has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, EPA must evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned regulation is preferable to other potentially effective and reasonably feasible alternatives EPA considered. The EPA interprets Executive Order 13045 as applying only to those regulatory actions that are based on health or safety risks, such that the analysis required under section 5-501 of the Executive Order has the potential to influence the regulation. The final amendments are not subject to Executive Order 13045 because they are based on technology performance and not on health and safety risks. H. Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution or Use This rule is not a ``significant energy action'' as defined in Executive Order 13211 (66 FR 28355, May 22, 2001) because it is not likely to have a significant adverse effect on the supply, distribution, or use of energy. Since there would be no change in energy consumption resulting from the final rule, EPA does not expect any price increase for any energy type. We also expect that there will be no impact on the import of foreign energy supplies, and no other adverse outcomes are expected to occur with regards to energy supplies. Therefore, EPA concludes that the final rule is not likely to have a significant adverse effect on the supply, distribution, or use of energy. I. National Technology Transfer Advancement Act Section 12(d) of the National Technology Transfer and Advancement Act (NTTAA) of 1995 (Pub. L. 104-113; 15 U.S.C. 272 note) directs the EPA to use voluntary consensus standards in regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) developed or adopted by one or more voluntary consensus bodies. The NTTAA directs EPA to provide Congress, through annual reports to the Office of Management and Budget (OMB), with explanations when an agency does not use available and applicable voluntary consensus standards. The MWC NSPS and emission guidelines involve technical standards. The EPA cites the following methods in the NSPS and emission guidelines: Methods 1, 3, 3A, 3B, 5, 6, 6A or 6C, 7 or 7A, 7C, 7D, or 7E, 9, 10, 10A or 10B, 19, 22, 23, 26, 26A, and 29 of 40 CFR part 60, appendix A; Performance Specifications (PS) 1, 2, 3, 4, and 11 of 40 CFR part 60, appendix B; and appendix F to 40 CFR part 60. In previous searches and review, which have been documented and placed in the docket, EPA identified four voluntary consensus standards that have already been incorporated by reference in 40 CFR 60.17. The voluntary consensus standard ASTM D6216 (1998), ``Standard Practice for Opacity Monitor Manufacturers to Certify Conformance with Design and Performance Specifications,'' is an acceptable alternative for opacity [[Page 27332]] monitor design specifications given in EPA's PS 1 (promulgated in March 1983). As a result, EPA incorporated ASTM D6216-98 by reference into PS 1 as the design specifications for opacity monitors in August 2000. (40 CFR part 60, appendix B.) The MWC NSPS and emission guidelines also incorporate by reference into 40 CFR part 60.17 ASME QRO-1-1994, ``Standard for the Qualification and Certification of Resource Recovery Facility Operators'' for operator qualification and certification; ASME PTC 4.1-1964 (reaffirmed 1991), ``Power Test Codes: Test Code for Steam Generating Units,'' for steam or feedwater flow; and ASME Interim Supplement 19.5 (6th Edition, 1971), ``Instruments and Apparatus: Application, Part II of Fluid Meters,'' for nozzle and orifice design. In this search and review, EPA conducted searches to identify voluntary consensus standards in addition to EPA methods in the MWC NSPS and emission guidelines. No applicable voluntary consensus standards were identified for EPA Methods 7D, 9, 10A, 19, and 22; and PS 3 and 4A. The search for emissions measurement procedures identified 27 voluntary consensus standards potentially applicable to the final amendments. One of the 27 voluntary consensus standards identified in this search was not available at the time the review was conducted for the purposes of the amendments because the standard is under development by a voluntary consensus body: ASTM WK3159 (Begun in 2003), ``Practice for Quality Assurance of Instrumental Monitoring Systems.'' The EPA determined that two of the remaining 26 standards identified for measuring emissions subject to the NSPS and emission guidelines were practical alternatives to EPA test methods for the purposes of the final amendments. EPA determined that 24 standards were not practical alternatives to EPA test methods, therefore, EPA does not intend to adopt these standards for this purpose. The reasons for EPA's determinations are discussed in a memorandum in the docket. EPA identified two voluntary consensus standards as alternatives to EPA test methods. ASME PTC 19-10-1981--Part 10, ``Flue and Exhaust Gas Analyses'' includes manual and instrumental methods of analyses for carbon monoxide, nitrogen oxides, oxygen, and sulfur dioxide. The manual methods of ASME PTC 19-10-1981--Part 10 for measuring the nitrogen oxide, oxygen, and sulfur dioxide content of exhaust gas are acceptable alternatives to Methods 3B, 6, 6A, 7, and 7C. The instrumental methods of ASME PTC 19-10-1981--Part 10 are not acceptable as a substitute for EPA Methods 3A, 6C, 7A, 7E, 10, and 10B. The instrumental methods are only general descriptions of procedures and are not true methods. Therefore, while some of the manual methods are acceptable alternatives to EPA methods, the instrumental methods are not. The voluntary consensus standard ASTM D6784-02, ``Standard Test Method for Elemental, Oxidized, Particle-Bound and Total Mercury Gas Generated from Coal-Fired Stationary Sources (Ontario Hydro Method),'' is an alternative to EPA Method 29 (portion for mercury only) as a method for measuring mercury. A full discussion of acceptable and unacceptable voluntary consensus standards is contained in a memorandum in the docket. J. Congressional Review Act The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing the final rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the final rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This final rule is not a major rule'' as defined by 5 U.S.C. 804(2). The final rule amendments to the standards of performance for new stationary sources is effective November 6, 2006. The final rule amendments to the emission guidelines for existing sources is effective on July 10, 2006. List of Subjects in 40 CFR Part 60 Environmental protection, Administrative practice and procedure, Air pollution control, Intergovernmental relations, Reporting and recordkeeping requirements. Dated: April 28, 2006. Stephen L. Johnson, Administrator. 0 For the reasons stated in the preamble, title 40, chapter I, of the Code of Federal Regulations is amended as follows: PART 60--[AMENDED] 0 1.

(a) This subpart contains emission guidelines and compliance schedules for the control of certain designated pollutants from certain municipal waste combustors in accordance with section 111(d) and section 129 of the Clean Air Act and subpart B of this part. The provisions in these emission guidelines apply instead of the provisions of Sec. 60.24(f) of subpart B of this part. (b) The following authorities are retained by EPA: (1) Approval of exemption claims in Sec. 60.32b(b)(1), (d), (e), (f)(1), (i)(1); (2) Approval of a nitrogen oxides trading program under Sec. 60.33b(d)(2); (3) Approval of major alternatives to test methods; (4) Approval of major alternatives to monitoring; (5) Waiver of recordkeeping; and (6) Performance test and data reduction waivers under Sec. 608(b). 0 3. Amend Sec. 60.31b by adding the definitions of ``EPA,'' ``Semi- suspension refuse-derived fuel-fired combustor/wet refuse-derived fuel process conversion,'' and ``Spreader stoker fixed floor refuse-derived fuel-fired combustor/100 percent coal capable'' in alphabetical order to read as follows: Sec. 60.31b Definitions. EPA means the Administrator of the U.S. EPA or employee of the U.S. EPA who is delegated to perform the specified task. * * * * * Semi-suspension refuse-derived fuel-fired combustor/wet refuse- derived fuel process conversion means a combustion unit that was converted from a wet refuse-derived fuel process to a dry refuse- derived fuel process, and because of constraints in the design of the system, includes a low furnace height (less than 60 feet between the grate and the roof) and a high waste capacity-to-undergrate air zone ratio (greater than 300 tons of waste per day (tpd) fuel per each undergrate air zone). Spreader stoker fixed floor refuse-derived fuel-fired combustor/100 percent coal capable means a spreader stoker type combustor with a fixed floor grate design that typically fires 100 percent refuse- derived fuel but is equipped to burn 100 percent coal instead of refuse-derived fuel to fulfill 100 percent steam or energy demand. 0 4.
