    ACTION: Proposed rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: This action proposes to reestablish new source performance 
    standards (NSPS) for new small municipal waste combustion (MWC) units. 
    When implemented, these NSPS will result in stringent emission limits 
    for organics (dioxins/furans), metals (cadmium, lead, mercury, and 
    particulate matter), and acid gases (hydrogen chloride, sulfur dioxide, 
    and nitrogen oxides). The NSPS for small MWC units were originally 
    promulgated in December 1995 but were vacated by the U.S. Court of 
    Appeals for the District of Columbia Circuit in March 1997. These 
    proposed NSPS are functionally equivalent to the 1995 NSPS.
    
    DATES: Comments: Comments on these proposed NSPS and comments on the 
    Information Collection Request (ICR) document associated with these 
    NSPS must be received on or before October 29, 1999.
        Public Hearing: A public hearing will be held if requests to speak 
    are received by September 14, 1999. The public hearing will provide 
    interested parties the opportunity to present data, views, or arguments 
    concerning these proposed NSPS. If requests to speak are received, the 
    public hearing will take place in Research Triangle Park, North 
    Carolina, approximately 30 days after August 30, 1999 and will begin at 
    10:00 a.m. A message regarding the status of the public hearing may be 
    accessed by calling (919) 541-5264.

        This list is not intended to be exhaustive, but rather provides a 
    guide regarding the entities EPA expects to regulate with these NSPS 
    for small MWC units. These NSPS would primarily impact facilities in 
    North American Industrial Classification System (NAICS) codes 562213 
    and 92411, formerly Standard Industrial Classification (SIC) codes 4953 
    and 9511, respectively. Not all facilities classified under these codes 
    would be affected. Other types of entities not listed in this table 
    could also be affected. To determine whether your facility would be 
    regulated by these NSPS, carefully examine the applicability criteria 
    in section II.A of this preamble. If you have any questions regarding 
    the applicability of this action to your small MWC unit or any other 
    question or comment, please submit comments to Docket No. A-98-18 or 
    refer to the FOR FURTHER INFORMATION CONTACT section.

    I. Background Information
    
        On September 20, 1994, EPA proposed NSPS for large and small MWC 
    units under 40 CFR part 60, subpart Eb. Those NSPS covered all MWC 
    units located at plants with an aggregate plant combustion capacity 
    larger than 35 megagrams per day of MSW which is approximately 39 tons 
    per day of MSW. The subpart Eb NSPS for large and small MWC units were 
    promulgated on December 19, 1995.
        The 1995 NSPS divided the MWC unit population into MWC units 
    located at large or small MWC plants based on the total aggregate 
    capacity of all MWC units at the MWC plant. The large plant category 
    comprised all MWC units located at MWC plants with aggregate plant 
    combustion capacities greater than 225 megagrams per day (approximately 
    248 tons per day). The small plant category comprised all MWC units 
    located at MWC plants with aggregate plant combustion capacities of 35 
    to 225 megagrams per day (approximately 39 to 248 tons per day).
        Following promulgation of the 1995 NSPS, a petition for review was 
    filed with the U.S. Court of Appeals for the District of Columbia 
    Circuit regarding the use of aggregate plant capacity as the basis for 
    initial categorization of the MWC unit population. An initial opinion 
    was issued by the court on December 6, 1996 (Davis County Solid Waste 
    Management and Recovery District v. EPA, 101 F. 3d 1395, D.C. Circuit, 
    1996). The initial opinion would have vacated (canceled) the 1995 NSPS 
    for both large and small MWC units.
        The EPA filed a petition for rehearing on February 4, 1997 
    requesting the court to reconsider the remedy portion of its opinion 
    and to vacate only the NSPS as they apply to small MWC units (units 
    with an individual unit capacity of 35 to 250 tons per day). The court 
    granted EPA's petition, reconsidered its opinion, and issued a revised 
    opinion on March 21, 1997 (Davis County Solid Waste Management and 
    Recovery District v. EPA, 108 F. 3d 1454, D.C. Circuit, 1997). The 
    revised opinion remanded to EPA the 1995 NSPS for the large MWC unit 
    category for amendment to be consistent with the court's final opinion 
    and vacated these NSPS only as they applied to small MWC units.
        Amendments to the 1995 NSPS incorporating the court's final opinion 
    were published on August 25, 1997 (62 FR 45116). The amendments made 
    the subpart Eb NSPS consistent with the court's decision and included 
    other minor technical corrections to improve clarity. The principal 
    change was to remove small MWC units from the applicability of subpart 
    Eb. This was accomplished by increasing the lower size definition 
    (cutoff) for large MWC
    
    [[Page 47278]]
    
    plants from 35 megagrams per day on a plant capacity basis to 250 tons 
    per day on a unit capacity basis. No adverse comments were received on 
    the proposal and the amendments became effective on October 24, 1997.
        Today's proposal would reestablish NSPS for new small MWC units 
    with combustion capacities of 35 to 250 tons per day of MSW.
    
    II. Summary of These Proposed NSPS
    
        This section summarizes these proposed NSPS for small MWC units, 
    including identification of the subcategories used in this proposal. 
    Overall, these proposed NSPS for small MWC units are functionally 
    equivalent to the 1995 NSPS for small MWC units. These proposed NSPS 
    retain subcategorization by aggregate plant capacity. The following two 
    subcategories are used in these NSPS for small MWC units: (1) Small MWC 
    units located at plants with aggregate plant capacities greater than 
    250 tons of MSW per day; and (2) small MWC units located at plants with 
    aggregate plant capacities less than or equal to 250 tons of MSW per 
    day. The court allowed this subcategorization as a second step after 
    first categorizing the MWC unit population into large MWC unit (subpart 
    Eb) and small MWC unit (subpart AAAA) categories.
    
    A. What Sources Would Be Regulated by These Proposed NSPS?
    
        Today's proposed NSPS, if promulgated in the current form, would 
    apply to each new MWC unit that has a combustion design capacity of 35 
    to 250 tons of MSW, and commenced construction after August 30, 1999 or 
    commenced modification or reconstruction 6 months after the date that 
    these NSPS rule are promulgated. Small MWC units that commenced 
    construction on or before August 30, 1999 are not covered under this 
    subpart. These units would be subject to the emission guidelines for 
    existing small MWC units that are proposed as subpart BBBB in a 
    separate part of today's Federal Register.
    
    B. What Pollutants Would Be Regulated by These Proposed NSPS?
    
        Section 129 of the Clean Air Act requires EPA to establish 
    numerical emission limits for dioxins/furans, cadmium, lead, mercury, 
    particulate matter, opacity, sulfur dioxide, hydrogen chloride, 
    nitrogen oxides, and carbon monoxide. Section 129 specifies that EPA 
    may also:
    
    * * * promulgate numerical emission limitations or provide for the 
    monitoring of post-combustion concentrations of surrogate 
    substances, parameters, or periods of residence times in excess of 
    stated temperatures with respect to pollutants other than those 
    listed [above] * * *
    
    Therefore, in addition to the proposed emission limits, EPA is 
    proposing limits for unit operating load, flue gas temperature at the 
    particulate matter control device inlet, and carbon feed rate as part 
    of the good combustion practice requirements. The EPA is also proposing 
    limits for control of fugitive ash emissions. All of these requirements 
    were contained in the 1995 NSPS.
    
    C. What Is the Format of the Proposed Emission Limits in These NSPS?
    
        The format of the emission limits in these proposed NSPS is 
    identical to the format of the 1995 NSPS. The format is in the form of 
    emission limits based on pollutant concentration. Alternative 
    percentage reduction requirements are provided for mercury, sulfur 
    dioxide, and hydrogen chloride. Opacity and fugitive ash requirements 
    in these NSPS are identical to the 1995 NSPS. In addition to 
    controlling stack emissions, these proposed NSPS incorporate the same 
    good combustion practice requirements (i.e., operator training, 
    operator certification, and operating requirements) that were included 
    in the 1995 NSPS. Additionally, this proposal includes a clarification 
    to the operator certification requirements to address periods when the 
    certified chief facility operators and certified shift supervisors must 
    be offsite. Section III.E provides more detail on these proposed 
    changes. Today's proposal also includes a revision to the carbon 
    injection requirements. See section III.F of this preamble for more 
    detail on the proposed changes.
    
    D. Where Can I Find a More Detailed Summary of These Proposed NSPS?
    
        A concise summary of these proposed NSPS can be found either in: 
    (1) tables 1 and 2 of the proposed subpart AAAA NSPS following this 
    preamble, or (2) the Technical Fact Sheet for this proposal that can be 
    downloaded from the EPA World Wide Web site for small MWC units (http:/
    /www.epa.gov/ttn/uatw/129/mwc/rimwc2.html).
    
    III. Changes in These Proposed NSPS Relative to the 1995 NSPS
    
        This section summarizes the changes in these proposed NSPS compared 
    to the 1995 NSPS. Overall, these NSPS are functionally equivalent to 
    the 1995 NSPS, with minimal changes. The most significant change since 
    the 1995 NSPS has been the use of the plain language style for 
    organizing and writing these NSPS. These proposed NSPS retain 
    subcategorization by aggregate plant capacity as allowed by the court.
    
    A. How Has the Conversion to Plain Language Affected These NSPS?
    
        The proposed NSPS are organized and written in the plain language 
    style. This plain language style has not affected the content of these 
    proposed NSPS compared to the 1995 NSPS. However, it has changed their 
    appearance. The EPA considers the question and answer style used with 
    plain language to be more user friendly and understandable to all 
    audiences when compared with previous rules that were not written in 
    this style. To improve the presentation of these NSPS requirements, 
    additional tables have been added.
    
    B. How Has the Size Definition of the Small MWC Unit Category Been 
    Revised?
    
        As a result of the 1997 court decision, both the upper and lower 
    size cutoffs have been changed for the small MWC unit category so that 
    the size cutoffs are based on the capacity of an individual MWC unit 
    rather than on the total capacity of the plant where an MWC unit is 
    located. Additionally, English units of measure are used instead of 
    metric units of measure.
    1. Upper Size Cutoff
        The upper size cutoff for small MWC units is proposed as 250 tons 
    per day on a unit capacity basis. In the 1995 NSPS, the upper size 
    cutoff was 225 megagrams per day (approximately 248 tons per day) based 
    on total plant capacity. The revised upper size cutoff is consistent 
    with the 1997 court ruling.
    2. Lower Size Cutoff
        The lower size cutoff is proposed as 35 tons per day on a unit 
    capacity basis to make both the upper size cutoff and lower size cutoff 
    consistent on a unit capacity basis. In the 1995 NSPS, the lower size 
    cutoff for small MWC units was 35 megagrams per day (approximately 39 
    tons per day) based on total plant capacity.
    
    C. How Has the Population of Small MWC Units Been Subcategorized in 
    These Proposed NSPS?
    
        As stated in the SUMMARY section, these proposed NSPS are 
    functionally equivalent to the 1995 NSPS and retain the use of 
    aggregate plant capacity to subcategorize small MWC units within these 
    proposed NSPS. The 1997 court decision allowed EPA to:
    
    * * * exercise its discretion to distinguish among units within a 
    category and create subcategories of small units, for which it can 
    then calculate MACT (maximum achievable
    
    [[Page 47279]]
    
    control technology) floors and standards separately.
    
        After first categorizing the MWC unit population into large and 
    small MWC units based on unit capacity, the court allowed EPA, as a 
    second step, to subcategorize by unit location (aggregate plant 
    capacity) at EPA discretion. The EPA has elected to retain the 
    subcategorization used in the 1995 NSPS. Therefore, today's proposal 
    divides the small MWC unit population into two classes: Class I and 
    Class II. Class I comprises small MWC units located at MWC plants with 
    an aggregate plant capacity greater than 250 tons of MSW per day. Class 
    II comprises small MWC units located at MWC plants with an aggregate 
    plant capacity less than or equal to 250 tons of MSW per day. The 
    establishment of these two classes preserves the subcategorization used 
    in the 1995 NSPS.
    
    D. Have Any Changes Been Made to the Emission Limits in These Proposed 
    NSPS?
    
        The proposed emission limits are identical to those established in 
    the 1995 NSPS. Based on a reevaluation of the best controlled units 
    within the small MWC unit population, EPA has concluded that the 
    performance of a SD/FF air pollution control system continues to 
    represent the MACT floor for new small MWC units. The supplemental use 
    of CI continues to represent MACT performance for mercury and dioxins/
    furans. This technology (SD/FF/CI) is the same technology basis of 
    these NSPS promulgated in 1995. With respect to nitrogen oxides, EPA 
    has concluded that a SNCR air pollution control system would represent 
    the basis of the MACT floor for nitrogen oxides for Class I units. 
    Since these technologies are the same as those used as the basis for 
    the 1995 NSPS, EPA is proposing the same emission limits that were 
    promulgated in the 1995 NSPS. The methods used to determine the new 
    source MACT floors, to select the technology basis of the new source 
    MACT, and to determine the emission limits are identical to the methods 
    described in the Federal Register notices and background documents for 
    the 1995 NSPS. The emission limits proposed for Class I units are the 
    same as the emission limits for large MWC units in the 1995 NSPS. The 
    emission limits proposed for Class II units are the same as the 
    emission limits for small MWC units in the 1995 NSPS.
    
    E. Have Any Changes Been Made to the Operator Certification 
    Requirements?
    
        One change is proposed for the operator certification section of 
    the good combustion practice requirements since the 1995 NSPS. In 
    response to questions since the 1995 NSPS were promulgated, EPA has 
    clarified what actions an MWC owner must take to continue operating an 
    MWC unit during times when the certified chief facility operator and 
    certified shift supervisor must be temporarily offsite for an extended 
    period of time when there are no other certified chief facility 
    operators or certified shift supervisors onsite. The EPA has addressed 
    this issue by adding specific requirements for MWC units during times 
    when the certified chief facility operator and certified shift 
    supervisor must be offsite. Different requirements apply depending on 
    the length of time the certified chief facility operator and certified 
    shift supervisor must be offsite. These changes have been added to 
    Sec. 60.1195 of these proposed NSPS.
    
    F. Have Any Changes Been Made to the Operating Practice Requirements?
    
        One change is proposed to the operating practice requirements since 
    the 1995 NSPS. The EPA has clarified how the required level of carbon 
    feed rate is established and how the required monitoring parameter and 
    quarterly carbon usage are used to determine compliance with the 
    operating practice requirements. As discussed below, this results in 
    two enforceable requirements for carbon feed rate.
        As in the 1995 NSPS, the MWC plant owner must select an operating 
    parameter (e.g., screw feeder speed) that can be used to calculate the 
    carbon feed rate. During each dioxin/furan and mercury stack test, the 
    total amount of carbon used during each stack test must be measured. 
    The total amount of carbon used during the test is divided by the 
    duration (hours) of the stack test to give an average carbon feed rate 
    in kilograms (or pounds) per hour. The MWC plant owner must also 
    monitor the selected operating parameter during each dioxin/furan and 
    mercury stack test and record the average operating parameter level. 
    After the dioxin/furan and mercury stack tests are complete, the MWC 
    plant owner must establish a relationship between the selected 
    operating parameter and the measured carbon feed rate so that the 
    selected parameter can be used to calculate the carbon feed rate. The 
    selected operating parameter must then be continuously monitored during 
    MWC unit operation and used to calculate the carbon feed rate. The 
    calculated carbon feed rate cannot fall below the carbon feed rate 
    measured during the dioxin/furan or mercury stack test (depending on 
    which test establishes the higher carbon feed rate).
        The 1995 NSPS did not clearly specify an averaging time for 
    calculating the carbon feed rate. Because the baseline carbon feed rate 
    is established as the average feed rate during the annual dioxin/furan 
    or mercury stack test, EPA is clarifying that the averaging time used 
    for monitoring the carbon feed rate (using parametric data) should be 
    of similar duration. Therefore, EPA is proposing an 8-hour block 
    averaging period for monitoring carbon feed rates. This would allow 
    facilities to compensate for interruptions in carbon feed rates (due to 
    calibration, malfunction, or repair) by offsetting the interruption 
    with an increase in carbon feed rates within the 8-hour averaging 
    period.
        The 1995 NSPS requirements have also been revised and clarified 
    relative to quarterly carbon usage. The EPA is proposing that MWC plant 
    owners calculate required plantwide carbon usage on a quarterly basis 
    and compare this required level of carbon usage to the actual amount of 
    carbon purchased and delivered to the MWC plant. After an average 
    carbon feed rate is established for an MWC unit based on the most 
    recent dioxin/furan or mercury stack test, the required quarterly 
    carbon usage level for the MWC unit is calculated by multiplying the 
    kilogram (or pound) per hour rate by the number of operating hours for 
    each quarter. Next, the required carbon usage for the plant is 
    calculated by summing this value for each small MWC unit located at the 
    plant.
        The MWC plant owner must then compare the required quarterly carbon 
    usage level, based on the carbon usage during the stack test and hours 
    of operation, with the amount of carbon purchased and delivered to the 
    MWC plant. The MWC plant owner must demonstrate that they are using the 
    required amount of carbon during each quarter. This comparison is done 
    on a plant basis rather than on a unit basis because MWC units 
    typically use a common carbon storage system; therefore, purchase, 
    delivery, and use of carbon are best tracked on a plant basis. If a 
    plant does not meet the quarterly carbon usage requirement, all units 
    at the plant would be considered out of compliance.
        A plant owner can choose to track quarterly carbon usage on an MWC 
    unit basis if that is practical at the plant. The required quarterly 
    carbon usage for each
    
    [[Page 47280]]
    
    individual MWC unit would then be compared to the carbon purchased and 
    delivered to that unit. In this case, if an MWC unit does not meet the 
    quarterly carbon usage requirement, only the one MWC unit, instead of 
    the entire MWC plant, would be considered out of compliance.
    
    G. Have Any Changes Been Made to the Monitoring and Stack Testing 
    Requirements?
    
        No changes are proposed to the monitoring and testing requirements 
    contained in the 1995 NSPS. However, to clarify differences between 
    stack testing and continuous emission monitoring requirements, these 
    topics have been addressed in different sections of these NSPS.
    
    H. Have Any Changes Been Made to the Recordkeeping and Reporting 
    Requirements?
    
        No significant changes are proposed to the recordkeeping and 
    reporting requirements since the 1995 NSPS. The EPA is proposing one 
    minor change to clarify recordkeeping and reporting of: (1) 8-hour 
    average calculated carbon feed rate, and (2) quarterly amounts of 
    carbon purchased and delivered. These changes make the reporting and 
    recordkeeping sections consistent with the carbon injection operating 
    practice requirements described above in section III.F.
    
    IV. What Would Be the Impacts Associated With These Proposed NSPS?
    
        This section describes the impacts (i.e., air, water, solid waste, 
    energy, cost, and economic impacts) of these proposed NSPS for small 
    MWC units. These proposed NSPS are functionally equivalent to these 
    NSPS promulgated in 1995. The impact analysis conducted to evaluate the 
    1995 NSPS still applies and is available at 59 FR 48198. The discussion 
    in this preamble focuses on the air, cost, and economic impacts of 
    these proposed NSPS.
        In the preamble for the 1995 NSPS, EPA determined that the water, 
    solid waste, and energy impacts associated with these proposed NSPS 
    were not significant. Because these proposed NSPS are the same as the 
    1995 NSPS, the water, solid waste, and energy impacts are not 
    significant.
        For more detail on the air, cost, and economic impacts of these 
    proposed NSPS, refer to the document entitled ``Economic Impact 
    Analysis: Small Municipal Waste Combustion Units--Section 111/129 
    Emission Guidelines and New Source Performance Standards'' (Docket No. 
    A-98-18).
    
    A. Air Impacts
    
        Table 1 presents national impacts of air emission reductions for 
    new small MWC units that would result from implementation of these 
    NSPS. These are fifth year impacts based on the assumption that one new 
    plant with two small MWC units would initiate operation each year.

    c For Class I units, nitrogen oxides emission reductions are expected to
      be approximately 40 percent. Class II units do not have a nitrogen
      oxides emission limit and are not expected to have any reductions in
      nitrogen oxides emissions. Since the distribution of new Class I and
      II units to be constructed are unknown, no mass reductions of nitrogen
      oxides are presented.
    
    B. Cost and Economic Impacts
    
        Approximately 90 small MWC units located at 41 plants are currently 
    operating in the United States. Based on trends in small MWC unit 
    construction over the past several years, EPA projects that about one 
    new small MWC plant will be constructed each year. It is estimated that 
    most new plants with small MWC units will have, on average, two small 
    MWC units onsite.
        To estimate the costs of these proposed NSPS for new small MWC 
    units, EPA has taken into account the various air pollution control 
    equipment that would need to be installed at new small MWC plants to 
    achieve these proposed NSPS. The cost estimates presented here, which 
    are in 1997 dollars, are the projected costs that a new MWC plant with 
    two small MWC units would incur to comply with these NSPS. These costs 
    are based on new small MWC units installing SD/FF/CI as the air 
    pollution control device system.
        The method used to estimate the cost and economic impacts of 
    today's proposal is consistent with the method used to estimate the 
    same impacts of the 1995 NSPS. For more details on the cost and 
    economic analysis, refer to the document entitled ``Economic Impact 
    Analysis: Small Municipal Waste Combustion Units--Section 111/129 
    Emission Guidelines and New Source Performance Standards'' (Docket No. 
    A-98-18).
        The EPA projects that the total annual cost (including annualized 
    capital and operating costs) for an MWC plant with two small MWC units 
    to comply with today's proposed NSPS would be approximately $1.6 
    million. Based on the current trend of MWC plant openings, in 5 years 
    there will be five MWC plants, with ten small MWC units subject to 
    these NSPS. In this case, the total annual cost of these NSPS would be 
    $8.1 million in the 5th year after promulgation of subpart AAAA.
    
    V. Companion Proposal for Existing Small MWC Units
    
        A companion proposal to these NSPS is being published in today's 
    Federal Register to establish emission guidelines for existing small 
    MWC units. Following promulgation, the emission guidelines for existing 
    small MWC units will be contained in 40 CFR part 60, subpart BBBB.
    
    VI. Administrative Requirements
    
    A. Public Hearing
    
        In accordance with section 307(d)(5) of the Clean Air Act, EPA will 
    hold a public hearing if individuals request to speak. If a public 
    hearing is held, EPA may ask clarifying questions during the
    
    [[Page 47281]]
    
    oral presentation but will not respond to the presentations or 
    comments. To provide an opportunity for all who may wish to speak, oral 
    presentations will be limited to 15 minutes each. Any member of the 
    public may submit written comments (see the DATES and ADDRESSES 
    sections). The EPA will consider written comments and supporting 
    information with equivalent weight to any oral statement and supporting 
    information presented at a public hearing.
    
    B. Docket
    
        The docket is an organized and complete file of the administrative 
    record compiled by EPA in the development of this proposal. Material is 
    added to the docket throughout the rule development process. The 
    principal purposes of the docket are: (1) To allow members of the 
    public to identify and locate documents so that they can effectively 
    participate in the rulemaking process, and (2) to serve as the record 
    in case of judicial review, except for interagency review material. The 
    docket numbers for these NSPS are Docket No. A-98-18 and associated 
    Docket Nos. A-90-45 and A-89-08, which have been incorporated by 
    reference into Docket No. A-98-18.
    
    C. National Technology Transfer and Advancement Act
    
        Under section 12(d) of the 1995 NTTAA (Pub. L. No. 104-113), all 
    Federal agencies are required to use voluntary consensus standards in 
    their regulatory and procurement 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, business practices) 
    developed or adopted by one or more voluntary consensus bodies. The 
    NTTAA requires Federal agencies to provide Congress, through annual 
    reports to the OMB, with explanations when an agency does not use 
    available and applicable voluntary consensus standards.
        Consistent with the NTTAA, the EPA conducted searches to identify 
    voluntary consensus standards for use in process and emissions 
    monitoring. The search for emissions monitoring procedures identified 
    20 voluntary consensus standards that appeared to have possible use in 
    lieu of EPA standard reference methods. However, after reviewing 
    available standards, EPA determined that 12 of the candidate consensus 
    standards identified for measuring emissions of pollutants or 
    surrogates subject to emission standards in the rule would not be 
    practical due to lack of equivalency, documentation, validation data, 
    and other important technical and policy considerations. Eight of the 
    remaining candidate consensus standards are new standards under 
    development that EPA plans to follow, review and consider adopting at a 
    later date.
        One consensus standard, ASTM D6216-98, appears to be practical for 
    EPA use in lieu of EPA performance specification 1 (40 CFR part 60, 
    appendix B). On September 23, 1998, EPA proposed incorporating by 
    reference ASTM D6216-98 under a separate rulemaking (63 FR 50824) that 
    would allow broader use and application of this consensus standard. The 
    EPA plans to complete this action in the near future. For these 
    reasons, EPA does not propose in these NSPS to adopt D6216-98 in lieu 
    of PS-1 requirements as it would be impractical for EPA to act 
    independently from separate rulemaking activities already undergoing 
    notice and comment.
        The EPA solicits comment on proposed emission monitoring 
    requirements proposed in these NSPS and specifically invites the public 
    to identify potentially-applicable voluntary consensus standards. 
    Commenters should also explain why this regulation should incorporate 
    these voluntary consensus standards, in lieu of EPA's standards. 
    Emission test methods and performance specifications submitted for 
    evaluation should be accompanied with a basis for the recommendation, 
    including method validation data and the procedure used to validate the 
    candidate method (if method other than Method 301, 40 CFR part 63, 
    appendix A was used).
        The EPA also conducted searches to identify voluntary consensus 
    standards for process monitoring and process operation. Candidate 
    voluntary consensus standards for process monitoring and process 
    operation were identified for: (1) MWC unit load level (steam output), 
    (2) designing, constructing, installing, calibrating, and using nozzles 
    and orifices, and (3) MWC plant operator certification requirements.
        One consensus standard by the ASME was identified for use in these 
    proposed NSPS for measurement of MWC unit load level (steam output). 
    The EPA believes this standard is practical to use in these proposed 
    NSPS as the method to measure MWC unit load. The EPA takes comment on 
    the incorporation by reference of ``ASME Power Test Codes: Test Code 
    for Steam Generating Units, Power Test Code 4.1--1964 (R1991)'' in 
    these proposed NSPS.
        A second consensus standard by ASME was identified for use in these 
    proposed NSPS for designing, constructing, installing, calibrating, and 
    using nozzles and orifices. The EPA believes this standard is practical 
    to use in these proposed NSPS for the design, construction, 
    installation, calibration, and use of nozzles and orifices. The EPA 
    takes comment on the incorporation by reference of ``American Society 
    of Mechanical Engineers Interim Supplement 19.5 on Instruments and 
    Apparatus: Application, Part II of Fluid Meters'', 6th edition (1971).
        A third consensus standard by ASME (QRO-1-1994) was identified for 
    use in these proposed NSPS for MWC plant operator certification 
    requirements instead of developing new operator certification 
    procedures. The EPA believes this standard is practical to use in these 
    proposed NSPS that require a chief facility operator and shift 
    supervisor to successfully complete the operator certification 
    procedures developed by ASME.
        Tables 3, 4, and 5 of these proposed NSPS list the EPA testing 
    methods and performance standards included in the proposed regulations. 
    Most of these standards have been used by States and industry for more 
    than 10 years. Nevertheless, under Sec. 60.8 of 40 CFR part 60, subpart 
    A, the proposal also allows any State or source to apply to EPA for 
    permission to use alternative methods in place of any of the EPA 
    testing methods or performance standards listed in Tables 3, 4, and 5.
    
    D. Paperwork Reduction Act
    
        The EPA submitted the information collection requirements in these 
    proposed NSPS to OMB for approval under the Paperwork Reduction Act, 44 
    U.S.C. 3501 et seq. The EPA prepared an ICR document (ICR No. 1900.01) 
    and a copy may be obtained from Sandy Farmer by mail at the OP, 
    Regulatory Information Division, U.S. Environmental Protection Agency 
    (2137), 401 M Street SW, Washington, DC 20460, by e-mail at 
    farmer.sandy@epamail.epa.gov'', or by calling (202) 260-2740. A copy 
    may also be downloaded from the Internet at: ``http://www.epa.gov/
    icr''.
        Comments are requested on the Agency's need for this information, 
    the accuracy of the provided burden estimates, and any suggested 
    methods for minimizing respondent burden, including through the use of 
    automated collection techniques. Send comments on the ICR to the 
    Director, OP Regulatory Information Division, U.S. Environmental 
    Protection Agency (2137), 401 M Street, SW, Washington,
    
    [[Page 47282]]
    
    DC 20460, and to the Office of Information and Regulatory Affairs, OMB, 
    725 17th Street, NW, Washington, DC 20503, marked ``Attention: Desk 
    Officer for EPA (ICR Tracking No. 1900.01)''. Include the ICR number in 
    any correspondence. Since OMB is required to make a decision concerning 
    the ICR between 30 and 60 days after August 30, 1999, a comment to OMB 
    is best assured of having its full effect if OMB receives it by 
    September 29, 1999. The final rule will respond to any OMB or public 
    comments on the information collection requirements contained in this 
    proposal.
        The information would be used by the Agency to identify new, 
    modified, or reconstructed MWC units subject to these NSPS and to 
    ensure that these MWC units undergo a preconstruction impact analysis. 
    The information would also be used to ensure that the small MWC unit 
    requirements are implemented properly and are complied with on a 
    continuous basis. Records and reports are necessary to enable EPA to 
    identify small MWC units that may not be in compliance with these NSPS. 
    Based on reported information, EPA would decide which small MWC units 
    should be inspected and what records or processes should be inspected. 
    The records that owners and operators of small MWC units maintain would 
    indicate to EPA whether personnel are operating and maintaining control 
    equipment properly.
        These NSPS are projected to affect six MWC units at three MWC 
    plants during the first 3 years immediately following promulgation. The 
    estimated average annual burden for industry for the first 3 years 
    after promulgation of these NSPS would be 8,559 person-hours annually 
    at a cost of $219,000 per year to meet the monitoring, recordkeeping, 
    and reporting requirements. The estimated average annualized burden for 
    the implementing agency would be 497 hours during the first 3 years at 
    a cost of $21,000 (including travel expenses).
        Burden means total time, effort, or financial resources expended by 
    persons to generate, maintain, retain, 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 48 CFR chapter 15.
    
    E. Regulatory Flexibility Act/Small Business Regulatory Enforcement 
    Fairness Act
    
        Section 605 of the RFA (5 U.S.C. 601 et seq.) requires Federal 
    agencies to give special consideration to the impact of regulations on 
    small entities, which are small businesses, small organizations, and 
    small governments. In 1996, the SBREFA amended the RFA to strengthen 
    the RFA's analytical and procedural requirements. The SBREFA also made 
    other changes to agency regulatory practice as it affects small 
    businesses and established a new mechanism to expedite congressional 
    review. The major purpose of these acts is to keep paperwork and 
    regulatory requirements from getting out of proportion to the scale of 
    the entities being regulated without compromising the objectives of the 
    Clean Air Act. If a regulation is likely to have a significant economic 
    impact on a substantial number of small entities, the EPA may give 
    special consideration to those small entities when analyzing regulatory 
    alternatives and drafting the regulation. Under these Acts, EPA must 
    generally prepare a regulatory flexibility analysis for a rule subject 
    to notice and comment rulemaking procedures unless the EPA certifies 
    that the rule will not have a significant economic impact on a 
    substantial number of small entities. Small entities include small 
    businesses, small not-for-profit enterprises, and small governmental 
    jurisdictions.
        Pursuant to the provisions of 5 U.S.C. 605(b), the EPA certifies 
    that these NSPS proposed today will not have a significant economic 
    impact on a substantial number of small entities. The EPA projects that 
    five small MWC plants will begin operation over the next 5 years, 
    averaging one MWC plant per year (Docket No. A-98-18).
        Impacts of this proposal are not significant for a substantial 
    number of small entities because few small entities use MWC units for 
    municipal solid waste disposal. The vast majority of small entities use 
    municipal solid waste landfills for disposal. A small entity 
    considering a new small MWC unit would have the opportunity to switch 
    to an alternative municipal solid waste disposal method, such as 
    municipal solid waste landfills, if the costs to comply with these NSPS 
    were considered prohibitive. Thus, the number of small entities that 
    would be significantly impacted by this proposal would not be 
    substantial.
        For a summary of the actions that EPA took to involve small 
    entities in the development of these proposed NSPS, refer to the 
    discussion of the Unfunded Mandates Reform Act in section VI.F. of 
    these Administrative Requirements.
    
    F. Unfunded Mandates Reform Act
    
        Title II of the 1995 UMRA, Pub. L. 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 to 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 allow 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 of why that alternative was not adopted. Before EPA 
    establishes any regulatory requirements that may significantly or 
    uniquely affect small governments, including tribal governments, it 
    must have developed under section 203 of the UMRA a small government 
    agency plan. 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 regulatory 
    proposals with significant Federal intergovernmental mandates, and 
    informing, educating, and advising small governments on compliance with 
    the regulatory requirements.
        The EPA has determined that these proposed NSPS do 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. The economic impact analysis for these 
    NSPS (Docket No. A-98-18) shows that the total annual costs of these 
    regulatory
    
    [[Page 47283]]
    
    requirements would be about $8.1 million annually (in 1997 dollars) in 
    the fifth year after promulgation. Thus, these proposed NSPS are not 
    subject to the requirements of sections 202 and 205 of the UMRA. 
    Although these NSPS are not subject to UMRA, EPA did prepare a cost-
    benefit analysis under section 202 of the UMRA for the 1995 NSPS. For a 
    discussion of how EPA complied with the UMRA for the 1995 NSPS, 
    including extensive consultations with State and local governments, see 
    the preamble to the 1995 NSPS (60 FR 65405-65412, December 19, 1995). 
    Because today's proposed NSPS are functionally equivalent to the 1995 
    NSPS, no additional consultations were necessary.
    
    G. 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 OMB review and the requirements of this Executive 
    Order. The Executive Order defines ``significant'' regulatory action as 
    one that is likely to lead to 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, EPA considers these 
    proposed NSPS to be ``not significant'' because these NSPS would not 
    have an annual effect on the economy of $100 million or more and do not 
    impose any additional control requirements above the 1995 NSPS. The 
    1995 NSPS were considered to be ``significant,'' and a full analysis 
    and review was conducted. However, these NSPS proposed today are 
    projected to have an impact of approximately $8.1 million annually in 
    the fifth year after promulgation of these NSPS (Docket No. A-98-18). 
    Therefore, these proposed NSPS are considered to be ``not significant'' 
    under Executive Order 12866 and will not be submitted to OMB for 
    review.
    
    H. Executive Order 12875--Enhancing the Intergovernmental Partnership
    
        Under Executive Order 12875, EPA may not issue a regulation that is 
    not required by statute and that creates a mandate upon a State, local, 
    or tribal government unless the Federal government provides the funds 
    necessary to pay the direct compliance costs incurred by those 
    governments or EPA consults with those governments. If EPA complies by 
    consulting with those governments, Executive Order 12875 requires EPA 
    to provide to the OMB a description of the extent of EPA's prior 
    consultation with representatives of affected State, local and tribal 
    governments, the nature of their concerns, copies of any written 
    communications from the governments, and a statement supporting the 
    need to issue the regulation. In addition, Executive Order 12875 
    requires EPA to develop an effective process permitting elected 
    officials and other representatives of State, local and tribal 
    governments ``to provide meaningful and timely input in the development 
    of regulatory proposals containing significant unfunded mandates.''
        The EPA has concluded that these NSPS may create a mandate on a 
    small number of city and county governments, and that the Federal 
    government would not provide the funds necessary to pay the direct 
    costs incurred by these city and county governments in complying with 
    the mandate. However, today's proposed NSPS do not impose any 
    additional costs or result in any additional control requirements above 
    those considered during promulgation of the 1995 NSPS. In developing 
    the 1995 NSPS, EPA consulted extensively with State and local 
    governments to enable them to provide meaningful and timely input in 
    the development of these NSPS. Because these proposed NSPS are the same 
    as the 1995 NSPS, these previous consultations still apply. For a 
    discussion of EPA's consultations with State and local governments, the 
    nature of the governments' concerns, and EPA's position supporting the 
    need to issue these NSPS, see the preamble to the 1995 NSPS (60 FR 
    65405-65413, December 19, 1995).
    
    I. Executive Order 12898--Federal Actions To Address Environmental 
    Justice in Minority Populations and Low-Income Populations
    
        Executive Order 12898 directs Federal agencies to ``determine 
    whether their programs, policies, and activities have 
    disproportionately high adverse human health or environmental effects 
    on minority populations and low-income populations'' (sections 3-301 
    and 3-302). In developing these NSPS for small MWC units, EPA analyzed 
    environmental justice issues that may be relevant to this proposal.
        The EPA conducted an impact analysis to determine the distribution 
    of minority and low-income groups in the surrounding area where MWC 
    units are located in the United States. The EPA reviewed the 
    demographic characteristics presented in this impact analysis (Docket 
    No. A-90-45) and other analyses. The EPA concluded that there is no 
    significant difference in ethnic makeup or income level in counties 
    where MWC units are located when compared to the average ethnic and 
    income levels of the respective States in which the units are located. 
    It is expected that these trends would also apply to future siting of 
    small MWC units.
        These proposed NSPS would require all new small MWC plants to use 
    the most stringent air pollution control technology currently available 
    for small MWC units. This upgrade in air pollution control technology 
    for new small MWC units would result in lowered air emissions (compared 
    to an absence of NSPS) from small MWC units, thereby improving human 
    health and the environment in areas where small MWC units are located. 
    Additionally, siting requirements for new small MWC units include two 
    public meetings, which would allow the public to comment on the siting 
    of any new small MWC unit before construction begins.
    
    J. Executive Order 13045--Protection of Children From Environmental 
    Health Risks and Safety Risks
    
        Executive Order 13045, ``Protection of Children from Environmental 
    Health Risks and Safety Risks'' (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, the Agency 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 considered by the Agency.
        The EPA interprets Executive Order 13045 as applying only to those 
    regulatory actions that are based on health or safety risks so that the 
    analysis required under section 5-501 of the
    
    [[Page 47284]]
    
    Executive Order has the potential to influence the regulation.
        These NSPS are not subject to Executive Order 13045 because they 
    are not economically significant as defined in Executive Order 12866 
    and because they are based on technology performance and not on health 
    and safety risks. A children's risk analysis was not performed for 
    these NSPS because no alternative technologies exist that would provide 
    greater stringency at a reasonable cost. Therefore, the results of any 
    such analysis would have no impact on the stringency decision.
    
    K. Executive Order 13084--Consultation and Coordination With Indian 
    Tribal Governments
    
        Under Executive Order 13084, EPA may not issue a regulation that is 
    not required by statute, that significantly or uniquely affects the 
    communities of Indian tribal governments, and that imposes substantial 
    direct compliance costs on those communities unless the Federal 
    government provides the funds necessary to pay the direct compliance 
    costs incurred by the tribal governments or EPA consults with those 
    governments. If EPA complies by consulting with those governments, 
    Executive Order 13084 requires EPA to provide to the OMB, in a 
    separately identified section of the preamble to the rule, a 
    description of the extent of EPA's prior consultation with 
    representatives of affected tribal governments, a summary of the nature 
    of their concerns, and a statement supporting the need to issue the 
    regulation. In addition, Executive Order 13084 requires EPA to develop 
    an effective process permitting elected officials and other 
    representatives of Indian tribal governments ``to provide meaningful 
    and timely input in the development of regulatory policies on matters 
    that significantly or uniquely affect their communities.''
        These NSPS do not significantly or uniquely affect the communities 
    of Indian tribal governments. The EPA is not aware of any existing or 
    planned small MWC units located in Indian territory. Accordingly, the 
    requirements of section 3(b) of Executive Order 13084 do not apply to 
    these NSPS.
    
    L. Executive Memorandum on Plain Language in Government Writing
    
        On June 1, 1998, President Clinton issued an Executive Memorandum 
    entitled ``Plain Language in Government Writing,'' which instructs 
    Federal agencies to use plain language in all proposed and final 
    rulemakings by January 1, 1999. Therefore, these proposed NSPS are 
    organized and written in a plain language format and style. This plain 
    language format and style do not alter the content or intent of this 
    proposal compared to the 1995 NSPS. The EPA considers this plain 
    language format and style to be more user friendly and understandable 
    to all audiences when compared with previous proposals that were not 
    written in plain language.

    Introduction
    
    
    Sec. 60.1000  What does this subpart do?
    
        This subpart establishes new source performance standards for new 
    small municipal waste combustion units.
    
    
    Sec. 60.1005  When does this subpart become effective?
    
        This subpart takes effect [the date 6 months after publication of 
    the final rule in the Federal Register]. Some of the requirements in 
    this subpart apply to municipal waste combustion unit planning and must 
    be completed before construction is commenced on the municipal waste 
    combustion unit. In particular, the preconstruction requirements in 
    Secs. 60.1050 through 60.1150 must be completed prior to commencing 
    construction. Other requirements (such as the emission limits) apply 
    when the municipal waste combustion unit begins operation.
    
    Applicability
    
    
    Sec. 60.1010  Does this subpart apply to my municipal waste combustion 
    unit?
    
        Yes, if your municipal waste combustion unit meets two criteria:
        (a) Your municipal waste combustion unit is a new municipal waste 
    combustion unit.
        (b) Your municipal waste combustion unit has the capacity to 
    combust at least 35 tons per day but no more than 250 tons per day of 
    municipal solid waste or refuse-derived fuel.
    
    
    Sec. 60.1015  What is a new municipal waste combustion unit?
    
        (a) A new municipal waste combustion unit is a municipal waste 
    combustion unit that meets either of two criteria:
        (1) Commenced construction after [date the final rule is published 
    in the Federal Register].
        (2) Commenced reconstruction or modification at least 6 months 
    after [date the final rule is published].
        (b) This subpart does not apply to your municipal waste combustion 
    unit if you make physical or operational changes to an existing 
    municipal waste
    
    [[Page 47286]]
    
    combustion unit primarily to comply with the emission guidelines in 
    subpart BBBB of this part. Such changes do not qualify as 
    reconstruction or modification under this subpart.
    
    
    Sec. 60.1020  Does this subpart allow any exemptions?
    
        (a) Small municipal waste combustion units that combust less than 
    11 tons per day. You are exempt from this subpart if you meet four 
    requirements:
        (1) Your municipal waste combustion unit is subject to a federally 
    enforceable operating permit limiting the amount of municipal solid

        (a) Yes. This subpart subcategorizes small municipal waste 
    combustion units into two groups based on the aggregate capacity of the 
    municipal waste combustion plant and the type of municipal waste 
    combustion unit as follows:
        (1) Class I Units. These are small municipal waste combustion units 
    that are located at municipal waste combustion plants with an aggregate 
    plant combustion capacity of more than 250 tons per day of municipal 
    solid waste. (See the definition of ``municipal waste combustion plant 
    capacity'' in Sec. 60.1465 for specification of which units at a plant 
    are included in the aggregate capacity calculation.)
        (2) Class II Units. These are small municipal waste combustion 
    units that are located at municipal waste combustion plants with an 
    aggregate
    
    [[Page 47287]]
    
    plant combustion capacity no more than 250 tons per day of municipal 
    solid waste. (See the definition of ``municipal waste combustion plant 
    capacity'' in Sec. 60.1465 for specification of which units at a plant 
    are included in the aggregate capacity calculation.)
        (b) The requirements for Class I and Class II units are identical 
    except for two items:
        (1) Class I units have a nitrogen oxide emission limit. Class II 
    units do not have a nitrogen oxide emission limit (see table 1 of this 
    subpart). Additionally, Class I units have continuous emission 
    monitoring, recordkeeping, and reporting requirements for nitrogen 
    oxides.
        (2) Class II units are eligible for the reduced testing option 
    provided in Sec. 60.1305.

    Good Combustion Practices: Operator Certification
    
    
    Sec. 60.1185  What types of operator certification must the chief 
    facility operator and shift supervisor obtain and by when must they 
    obtain it?
    
        (a) Each chief facility operator and shift supervisor must obtain 
    and keep a current provisional operator certification from the American 
    Society of Mechanical Engineers (QRO-1-1994 (incorporated by reference 
    in Sec. 60.17 of subpart A of this part)) or a current provisional 
    operator certification from your State certification program.
        (b) Each chief facility operator and shift supervisor must obtain a 
    provisional certification by the later of three dates:
        (1) Six months after the municipal waste combustion unit starts up.
        (2) One year after [date of publication of the final rule].
        (3) Six months after they transfer to the municipal waste 
    combustion unit or 6 months after they are hired to work at the 
    municipal waste combustion unit.
        (c) Each chief facility operator and shift supervisor must take one 
    of three actions:
        (1) Obtain a full certification from the American Society of 
    Mechanical Engineers or a State certification program in your State.
    
    [[Page 47290]]
    
        (2) Schedule a full certification exam with the American Society of 
    Mechanical Engineers (QRO-1-1994 (incorporated by reference in 
    Sec. 60.17 of subpart A of this part)).
        (3) Schedule a full certification exam with your State 
    certification program.
        (d) The chief facility operator and shift supervisor must obtain 
    the full certification or be scheduled to take the certification exam 
    by the later of three dates:
        (1) Six months after the municipal waste combustion unit starts up.
        (2) One year after [date of publication of the final rule].
        (3) Six months after they transfer to the municipal waste 
    combustion unit or 6 months after they are hired to work at the 
    municipal waste combustion unit.
    
    
    Sec. 60.1190  After the required date for operator certification, who 
    may operate the municipal waste combustion unit?
    
        After the required date for full or provisional certifications, you 
    must not operate your municipal waste combustion unit unless one of 
    four employees is on duty:
        (a) A fully certified chief facility operator.
        (b) A provisionally certified chief facility operator who is 
    scheduled to take the full certification exam.
        (c) A fully certified shift supervisor.
        (d) A provisionally certified shift supervisor who is scheduled to 
    take the full certification exam.
    
    
    Sec. 60.1195  What if all the certified operators must be temporarily 
    offsite?
    
        If the certified chief facility operator and certified shift 
    supervisor both must leave your municipal waste combustion unit, a 
    provisionally certified control room operator at the municipal waste 
    combustion unit may fulfill the certified operator requirement. 
    Depending on the length of time that a certified chief facility 
    operator and certified shift supervisor are away, you must meet one of 
    three criteria:
        (a) When the certified chief facility operator and certified shift 
    supervisor are both offsite for less than 8 hours, and no other 
    certified operator is onsite, the provisionally certified control room 
    operator may perform those duties without notice to, or approval by, 
    the Administrator.
        (b) When the certified chief facility operator and certified shift 
    supervisor are offsite for more than 8 hours, but less than 2 weeks, 
    and no other certified operator is onsite, the provisionally certified 
    control room operator may perform those duties without notice to, or 
    approval by, the Administrator. However, you must record the period 
    when the certified chief facility operator and certified shift 
    supervisor are offsite and include this information in the annual 
    report as specified under Sec. 60.1410(l).
        (c) When the certified chief facility operator and certified shift 
    supervisor are offsite for more than 2 weeks, and no other certified 
    operator is onsite, the provisionally certified control room operator 
    may perform those duties without notice to, or approval by, the 
    Administrator. However, you must take two actions:
        (1) Notify the Administrator in writing. In the notice, state what 
    caused the absence and what you are doing to ensure that a certified 
    chief facility operator or certified shift supervisor is onsite.
        (2) Submit a status report and corrective action summary to the 
    Administrator every 4 weeks following the initial notification. If the 
    Administrator notifies you that your status report or corrective action 
    summary is disapproved, the municipal waste combustion unit may 
    continue operation for 90 days, but then must cease operation. If 
    corrective actions are taken in the 90-day period such that the 
    Administrator withdraws the disapproval, municipal waste combustion 
    unit operation may continue.
    
    Good Combustion Practices: Operating Requirements
    
    
    Sec. 60.1200  What are the operating practice requirements for my 
    municipal waste combustion unit?
    
        (a) You must not operate your municipal waste combustion unit at 
    loads greater than 110 percent of the maximum demonstrated unit load of 
    the municipal waste combustion unit (4-hour block average), as 
    specified under ``Definitions'' (Sec. 60.1465).
        (b) You must not operate your municipal waste combustion unit so 
    that the temperature at the inlet of the particulate matter control 
    device exceeds 17 deg.C above the maximum demonstrated temperature of 
    the particulate matter control device (4-hour block average), as 
    specified under ``Definitions'' (Sec. 60.1465).
        (c) If your municipal waste combustion unit uses activated carbon 
    to control dioxin/furan or mercury emissions, you must maintain an 8-
    hour block average carbon feed rate at or above the highest average 
    level established during the most recent dioxin/furan or mercury test.
        (d) If your municipal waste combustion unit uses activated carbon 
    to control dioxin/furan or mercury emissions, you must evaluate total 
    carbon usage for each calendar quarter. The total amount of carbon 
    purchased and delivered to your municipal waste combustion plant must 
    be at or above the required quarterly usage of carbon. At your option, 
    you may choose to evaluate required quarterly carbon usage on a 
    municipal waste combustion unit basis for each individual municipal 
    waste combustion unit at your plant. Calculate the required quarterly 
    usage of carbon using the appropriate equation in Sec. 60.1460(f).
        (e) Your municipal waste combustion unit is exempt from limits on 
    load level, temperature at the inlet of the particulate matter control 
    device, and carbon feed rate during any of five situations:
        (1) During your annual tests for dioxins/furans.
        (2) During your annual mercury tests (for carbon feed rate 
    requirements only).
        (3) During the 2 weeks preceding your annual tests for dioxins/
    furans.
        (4) During the 2 weeks preceding your annual mercury tests (for 
    carbon feed rate requirements only).
        (5) Whenever the Administrator or delegated State authority permits 
    you to do any of five activities:
        (i) Evaluate system performance.
        (ii) Test new technology or control technologies.
        (iii) Perform diagnostic testing.
        (iv) Perform other activities to improve the performance of your 
    municipal waste combustion unit.
        (v) Perform other activities to advance the state of the art for 
    emission controls for your municipal waste combustion unit.
    
    
    Sec. 60.1205  What happens to the operating requirements during periods 
    of startup, shutdown, and malfunction?
    
        (a) The operating requirements of this subpart apply at all times 
    except during periods of municipal waste combustion unit startup, 
    shutdown, or malfunction.
        (b) Each startup, shutdown, or malfunction must not last for longer 
    than 3 hours.
    
    Emission Limits
    
    
    Sec. 60.1210  What pollutants are regulated by this subpart?
    
        Eleven pollutants, in four groupings, are regulated:
        (a) Organics. Dioxins/furans.
        (b) Metals. 
        (1) Cadmium.

        (3) Sulfur dioxide.
        (d) Other.
        (1) Carbon monoxide.
        (2) Fugitive ash.
    
    
    Sec. 60.1215  What emission limits must I meet? By when?
    
        You must meet the emission limits specified in tables 1 and 2 of 
    this subpart. You must meet these limits 60 days after your municipal 
    waste combustion unit reaches the maximum load level but no later than 
    180 days after its initial startup.
    
    
    Sec. 60.1220  What happens to the emission limits during periods of 
    startup, shutdown, and malfunction?
    
        (a) The emission limits of this subpart apply at all times except 
    during periods of municipal waste combustion unit startup, shutdown, or 
    malfunction.
        (b) Each startup, shutdown, or malfunction must not last for longer

    Continuous Emission Monitoring
    
    
    Sec. 60.1225  What types of continuous emission monitoring must I 
    perform?
    
        To continuously monitor emissions, you must perform four tasks:
        (a) Install continuous emission monitoring systems for certain 
    gaseous pollutants.
        (b) Make sure your continuous emission monitoring systems are 
    operating correctly.
        (c) Make sure you obtain the minimum amount of monitoring data.
        (d) Install a continuous opacity monitoring system.
    
    
    Sec. 60.1230  What continuous emission monitoring systems must I 
    install for gaseous pollutants?
    
        (a) You must install, calibrate, maintain, and operate continuous 
    emission monitoring systems for oxygen (or carbon dioxide), sulfur 
    dioxide, and carbon monoxide. If you operate a Class I municipal waste 
    combustion unit, also install, calibrate, maintain, and operate a 
    continuous emission monitoring system for nitrogen oxides. Install the 
    continuous emission monitoring system for sulfur dioxide and nitrogen 
    oxides at the outlet of the air pollution control device.
        (b) You must install, evaluate, and operate each continuous 
    emission monitoring system according to the ``Monitoring Requirements'' 
    in Sec. 60.13 of subpart A of this part.
        (c) You must monitor the oxygen (or carbon dioxide) concentration 
    at each location where you monitor sulfur dioxide and carbon monoxide. 
    Additionally, if you operate a Class I municipal waste combustion unit, 
    you must also monitor the oxygen (or carbon dioxide) concentration at 
    the location where you monitor nitrogen oxides.
        (d) You may choose to monitor carbon dioxide instead of oxygen as a 
    diluent gas. If you choose to monitor carbon dioxide, then an oxygen 
    monitor is not required, and you must follow the requirements in 
    Sec. 60.1255.
        (e) If you choose to demonstrate compliance by monitoring the 
    percent reduction of sulfur dioxide, you must also install a continuous 
    emission monitoring system for sulfur dioxide and oxygen (or carbon 
    dioxide) at the inlet of the air pollution control device.
    
    
    Sec. 60.1235  How are the data from the continuous emission monitoring 
    systems used?
    
        You must use data from the continuous emission monitoring systems 
    for sulfur dioxide, nitrogen oxides, and carbon monoxide to demonstrate 
    continuous compliance with the emission limits specified in tables 1 
    and 2 of this subpart. To demonstrate compliance for dioxins/furans, 
    cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride, 
    and fugitive ash, see Sec. 60.1290.
    
    
    Sec. 60.1240  How do I make sure my continuous emission monitoring 
    systems are operating correctly?
    
        (a) Conduct initial, daily, quarterly, and annual evaluations of 
    your continuous emission monitoring systems that measure oxygen (or 
    carbon dioxide), sulfur dioxide, nitrogen oxides (Class I municipal 
    waste combustion units only), and carbon monoxide.
        (b) Complete your initial evaluation of the continuous emission 
    monitoring systems within 60 days after your municipal waste combustion 
    unit reaches the maximum load level at which it will operate, but no 
    later than 180 days after its initial startup.
        (c) For initial and annual evaluations, collect data concurrently 
    (or within 30 to 60 minutes) using your oxygen (or carbon dioxide) 
    continuous emission monitoring system, your sulfur dioxide, nitrogen 
    oxides, or carbon monoxide continuous emission monitoring systems, as 
    appropriate, and the appropriate test methods specified in table 3 of 
    this subpart. Collect these data during each initial and annual 
    evaluation of your continuous emission monitoring systems following the 
    applicable performance specifications in appendix B of this part. Table 
    4 of this subpart shows the performance specifications that apply to 
    each continuous emission monitoring system.
        (d) Follow the quality assurance procedures in Procedure 1 of 
    appendix F of this part for each continuous emission monitoring system. 
    These procedures include daily calibration drift and quarterly accuracy 
    determinations.
    
    
    Sec. 60.1245  Am I exempt from any appendix B or appendix F 
    requirements to evaluate continuous emission monitoring systems?
    
        Yes, the accuracy tests for your sulfur dioxide continuous emission 
    monitoring system require you to also evaluate your oxygen (or carbon 
    dioxide) continuous emission monitoring system. Therefore, your oxygen 
    (or carbon dioxide) continuous emission monitoring system is exempt 
    from two requirements:
        (a) Section 2.3 of performance specification 3 in appendix B of 
    this part (relative accuracy requirement).
        (b) Section 5.1.1 of appendix F of this part (relative accuracy 
    test audit).
    
    
    Sec. 60.1250  What is my schedule for evaluating continuous emission 
    monitoring systems?
    
        (a) Conduct annual evaluations of your continuous emission 
    monitoring systems no more than 12 months after the previous evaluation 
    was conducted.
        (b) Evaluate your continuous emission monitoring systems daily and 
    quarterly as specified in appendix F of this part.
    
    
    Sec. 60.1255  What must I do if I choose to monitor carbon dioxide 
    instead of oxygen as a diluent gas?
    
        You must establish the relationship between oxygen and carbon 
    dioxide during the initial evaluation of your continuous emission 
    monitoring system. You may reestablish the relationship during annual 
    evaluations. To establish the relationship use three procedures:
        (a) Use EPA Reference Method 3 or 3A to determine oxygen 
    concentration at the location of your carbon dioxide monitor.
        (b) Conduct at least three test runs for oxygen. Make sure each 
    test run represents a 1-hour average and that sampling continues for at 
    least 30 minutes in each hour.
        (c) Use the fuel-factor equation in EPA Reference Method 3B to 
    determine the relationship between oxygen and carbon dioxide.
    
    
    Sec. 60.1260  What is the minimum amount of monitoring data I must 
    collect with my continuous emission monitoring systems and is this 
    requirement enforceable?
    
        (a) Where continuous emission monitoring systems are required, 
    obtain 1-hour arithmetic averages. Make sure the averages for sulfur 
    dioxide, nitrogen oxides, and carbon monoxide are in parts per million 
    by dry volume at 7 percent oxygen (or the equivalent carbon dioxide 
    level). Use the 1-hour
    
    [[Page 47292]]
    
    averages of oxygen (or carbon dioxide) data from your continuous 
    emission monitoring system to determine the actual oxygen (or carbon 
    dioxide) level and to calculate emissions at 7 percent oxygen (or the 
    equivalent carbon dioxide level).
        (b) Obtain at least two data points per hour in order to calculate 
    a valid 1-hour arithmetic average. Section 60.13(e)(2) of subpart A of 
    this part requires your continuous emission monitoring systems to 
    complete at least one cycle of operation (sampling, analyzing, and data 
    recording) for each 15-minute period.
        (c) Obtain valid 1-hour averages for 75 percent of the operating 
    hours per day and for 90 percent of the operating days per calendar 
    quarter. An operating day is any day the unit combusts any municipal 
    solid waste or refuse-derived fuel.
        (d) If you do not obtain the minimum data required in paragraphs 
    (a) through (c) of this section, you are in violation of this data 
    collection requirement regardless of the emission level monitored, and 
    you must notify the Administrator according to Sec. 60.1410(e).
        (e) If you do not obtain the minimum data required in paragraphs 
    (a) and (c) of this section, you must still use all valid data from the 
    continuous emission monitoring systems in calculating emission 
    concentrations and percent reductions in accordance with Sec. 60.1265.
    
    
    Sec. 60.1265  How do I convert my 1-hour arithmetic averages into the 
    appropriate averaging times and units for this standard?
    
        (a) Use the equation in Sec. 60.1460(a) to calculate emissions at 7 
    percent oxygen.
        (b) Use EPA Reference Method 19, section 4.3, to calculate the 
    daily geometric average concentrations of sulfur dioxide emissions. If 
    you are monitoring the percent reduction of sulfur dioxide, use EPA 
    Reference Method 19, section 5.4, to determine the daily geometric 
    average percent reduction of potential sulfur dioxide emissions.
        (c) If you operate a Class I municipal waste combustion unit, use 
    EPA Reference Method 19, section 4.1, to calculate the daily arithmetic 
    average for concentrations of nitrogen oxides.
        (d) Use EPA Reference Method 19, section 4.1, to calculate the 4-
    hour or 24-hour daily block averages (as applicable) for concentrations 
    of carbon monoxide.
    
    
    Sec. 60.1270  What is required for my continuous opacity monitoring 
    system and how are the data used?
    
        (a) Install, calibrate, maintain, and operate a continuous opacity 
    monitoring system.
        (b) Install, evaluate, and operate each continuous opacity 
    monitoring system according to Sec. 60.13 of subpart A of this part.
        (c) Complete an initial evaluation of your continuous opacity 
    monitoring system according to performance specification 1 in appendix 
    B of this part. Complete this evaluation within 60 days after your 
    municipal waste combustion unit reaches the maximum load level at which 
    it will operate, but no more than 180 days after its initial startup.
        (d) Complete each annual evaluation of your continuous opacity 
    monitoring system no more than 12 months after the previous evaluation.
        (e) Use tests conducted according to EPA Reference Method 9, as 
    specified in Sec. 60.1300, to determine compliance with the emission 
    limit for opacity in table 1 of this subpart. The data obtained from 
    your continuous opacity monitoring system are not used to determine 
    compliance with the limit on opacity emissions.
    
    
    Sec. 60.1275  What additional requirements must I meet for the 
    operation of my continuous emission monitoring systems and continuous 
    opacity monitoring system?
    
        Use the required span values and applicable performance 
    specifications in table 4 of this subpart.
    
    
    Sec. 60.1280  What must I do if my continuous emission monitoring 
    system is temporarily unavailable to meet the data collection 
    requirements?
    
        Refer to table 5 of this subpart. It shows alternate methods for 
    collecting data when these systems malfunction or when repairs, 
    calibration checks, or zero and span checks keep you from collecting 
    the minimum amount of data.
    
    Stack Testing
    
    
    Sec. 60.1285  What types of stack tests must I conduct?
    
        Conduct initial and annual stack tests to measure the emission 
    levels of dioxins/furans, cadmium, lead, mercury, particulate matter, 
    opacity, hydrogen chloride, and fugitive ash.
    
    
    Sec. 60.1290  How are the stack test data used?
    
        You must use results of stack tests for dioxins/furans, cadmium, 
    lead, mercury, particulate matter, opacity, hydrogen chloride, and 
    fugitive ash to demonstrate compliance with the emission limits in 
    table 1 of this subpart. To demonstrate compliance for carbon monoxide, 
    nitrogen oxides, and sulfur dioxide, see Sec. 60.1235.
    
    
    Sec. 60.1295  What schedule must I follow for the stack testing?
    
        (a) Conduct initial stack tests for the pollutants listed in 
    Sec. 60.1285 within 60 days after your municipal waste combustion unit 
    reaches the maximum load level at which it will operate, but no later 
    than 180 days after its initial startup.
        (b) Conduct annual stack tests for these pollutants after the 
    initial stack test. Conduct each annual stack test within 12 months 
    after the previous stack test.
    
    
    Sec. 60.1300  What test methods must I use to stack test?
    
        (a) Follow table 5 of this subpart to establish the sampling 
    location and to determine pollutant concentrations, number of traverse 
    points, individual test methods, and other specific testing 
    requirements for the different pollutants.
        (b) Make sure that stack tests for all these pollutants consist of 
    at least three test runs, as specified in Sec. 60.8 (Performance Tests) 
    of subpart A of this part. Use the average of the pollutant emission 
    concentrations from the three test runs to determine compliance with 
    the emission limits in table 1 of this subpart.
        (c) Obtain an oxygen (or carbon dioxide) measurement at the same 
    time as your pollutant measurements to determine diluent gas levels, as 
    specified in Sec. 60.1230.
        (d) Use the equations in Sec. 60.1460(a) to calculate emission 
    levels at 7 percent oxygen (or an equivalent carbon dioxide basis), the 
    percent reduction in potential hydrogen chloride emissions, and the 
    reduction efficiency for mercury emissions. See the individual test 
    methods in table 5 of this subpart for other required equations.
    
    
    Sec. 60.1305  May I conduct stack testing less often?
    
        (a) You may test less often if you own or operate a Class II 
    municipal waste combustion unit and if all stack tests for a given 
    pollutant over 3 consecutive years show you comply with the emission 
    limit. In this case, you are not required to conduct a stack test for 
    that pollutant for the next 2 years. However, you must conduct another 
    stack test within 36 months of the anniversary date of the third 
    consecutive stack test that shows you comply with the emission limit. 
    Thereafter, you must perform stack tests every third year but no later 
    than 36 months following the
    
    [[Page 47293]]
    
    previous stack tests. If a stack test shows noncompliance with an 
    emission limit, you must conduct annual stack tests for that pollutant 
    until all stack tests over a 3-year period show compliance.
        (b) You can test less often if you own or operate a municipal waste 
    combustion plant that meets two conditions. First, you have multiple 
    municipal waste combustion units onsite that are subject to this 
    subpart. Second, all these municipal waste combustion units have 
    demonstrated levels of dioxin/furan emissions no more than 7 nanograms 
    per dry standard cubic meter (total mass) for 2 consecutive years. In 
    this case, you may choose to conduct annual stack tests on only one 
    municipal waste combustion unit per year at your plant.
        (1) Conduct the stack test no more than 12 months following a stack 
    test on any municipal waste combustion unit subject to this subpart at 
    your plant. Each year, test a different municipal waste combustion unit 
    subject to this subpart and test all municipal waste combustion units 
    subject to this subpart in a sequence that you determine. Once you 
    determine a testing sequence, it must not be changed without approval 
    by the Administrator.
        (2) If each annual stack test shows levels of dioxin/furan 
    emissions less than 7 nanograms per dry standard cubic meter (total 
    mass), you may continue stack tests on only one municipal waste 
    combustion unit subject to this subpart per year.
        (3) If any annual stack test indicates levels of dioxin/furan 
    emissions greater than 7 nanograms per dry standard cubic meter (total 
    mass), conduct subsequent annual stack tests on all municipal waste 
    combustion units subject to this subpart at your plant. You may return 
    to testing one municipal waste combustion unit subject to this subpart 
    per year if you can demonstrate dioxin/furan emission levels less than 
    7 nanograms per dry standard cubic meter (total mass) for all municipal 
    waste combustion units at your plant subject to this subpart for 2 
    consecutive years.
    
    
    Sec. 60.1310  May I deviate from the 12-month testing schedule if 
    unforeseen circumstances arise?
    
        You may not deviate from the 12-month testing schedules specified 
    in Secs. 60.1295(b) and 60.1305(b)(1) unless you apply to the 
    Administrator for an alternative schedule, and the Administrator 
    approves your request for alternative scheduling prior to the date on 
    which you would otherwise have been required to conduct the next stack 
    test.
    
    Other Monitoring Requirements
    
    
    Sec. 60.1315  Must I meet other requirements for continuous monitoring?
    
        You must also monitor three operating parameters:
        (a) Load level of each municipal waste combustion unit.
        (b) Temperature of flue gases at the inlet of your particulate 
    matter air pollution control device.
        (c) Carbon feed rate if activated carbon is used to control dioxin/
    furan or mercury emissions.
    
    
    Sec. 60.1320  How do I monitor the load of my municipal waste 
    combustion unit?
    
        (a) If your municipal waste combustion unit generates steam, you 
    must install, calibrate, maintain, and operate a steam flowmeter or a 
    feed water flowmeter and meet five requirements:
        (1) Continuously measure and record the measurements of steam (or 
    feed water) in kilograms per hour (or pounds per hour).
        (2) Calculate your steam (or feed water) flow in 4-hour block 
    averages.
        (3) Calculate the steam (or feed water) flow rate using the method 
    in ``American Society of Mechanical Engineers Power Test Codes: Test 
    Code for Steam Generating Units, Power Test Code 4.1--1964 (R1991),'' 
    section 4 (incorporated by reference in Sec. 60.17 of subpart A of this 
    part).
        (4) Design, construct, install, calibrate, and use nozzles or 
    orifices for flow rate measurements, using the recommendations in 
    ``American Society of Mechanical Engineers Interim Supplement 19.5 on 
    Instruments and Apparatus: Application, Part II of Fluid Meters,'' 6th 
    Edition (1971), chapter 4 (incorporated by reference in Sec. 60.17 of 
    subpart A of this part).
        (5) Before each dioxin/furan stack test, or at least once a year, 
    calibrate all signal conversion elements associated with steam (or feed 
    water) flow measurements according to the manufacturer instructions.
        (b) If your municipal waste combustion unit does not generate 
    steam, you must determine, to the satisfaction of the Administrator, 
    one or more operating parameters that can be used to continuously 
    estimate load level (for example, the feed rate of municipal solid 
    waste or refuse-derived fuel). You must continuously monitor the 
    selected parameters.
    
    
    Sec. 60.1325  How do I monitor the temperature of flue gases at the 
    inlet of my particulate matter control device?
    
        You must install, calibrate, maintain, and operate a device to 
    continuously measure the temperature of the flue gas stream at the 
    inlet of each particulate matter control device.
    
    
    Sec. 60.1330  How do I monitor the injection rate of activated carbon?
    
        If your municipal waste combustion unit uses activated carbon to 
    control dioxin/furan or mercury emissions, you must meet three 
    requirements:
        (a) Select a carbon injection system operating parameter that can 
    be used to calculate carbon feed rate (for example, screw feeder 
    speed).
        (b) During each dioxin/furan and mercury stack test, determine the 
    average carbon feed rate in kilograms (or pounds) per hour. Also, 
    determine the average operating parameter level that correlates to the 
    carbon feed rate. Establish a relationship between the operating 
    parameter and the carbon feed rate in order to calculate the carbon 
    feed rate based on the operating parameter level.
        (c) Continuously monitor the selected operating parameter during 
    all periods when the municipal waste combustion unit is operating and 
    combusting waste and calculate the 8-hour block average carbon feed 
    rate in kilograms (or pounds) per hour, based on the selected operating 
    parameter. When calculating the 8-hour block average, do two things:
        (1) Exclude hours when the municipal waste combustion unit is not 
    operating.
        (2) Include hours when the municipal waste combustion unit is 
    operating but the carbon feed system is not working correctly.
    
    
    Sec. 60.1335  What is the minimum amount of monitoring data I must 
    collect with my continuous parameter monitoring systems and is this 
    requirement enforceable?
    
        (a) Where continuous parameter monitoring systems are used, obtain 
    1-hour arithmetic averages for three parameters:
        (1) Load level of the municipal waste combustion unit.
        (2) Temperature of the flue gases at the inlet of your particulate 
    matter control device.
        (3) Carbon feed rate if activated carbon is used to control dioxin/
    furan or mercury emissions.
        (b) Obtain at least two data points per hour in order to calculate 
    a valid 1-hour arithmetic average.
        (c) Obtain valid 1-hour averages for, at a minimum, 75 percent of 
    the operating hours per day and for 90 percent of the operating days 
    per calendar quarter. An operating day is any day the unit combusts any 
    municipal solid waste or refuse-derived fuel.
        (d) If you do not obtain the minimum data required in paragraphs 
    (a) through (c) of this section, you are in violation
    
    [[Page 47294]]
    
    of this data collection requirement and you must notify the 
    Administrator according to Sec. 60.1410(e).

    Sec. 60.1435  What is an air curtain incinerator?
    
        An air curtain incinerator operates by forcefully projecting a 
    curtain of air across an open chamber or open pit in which combustion 
    occurs. Incinerators of this type can be constructed above or below 
    ground and with or without refractory walls and floor.
    
    
    Sec. 60.1440  What is yard waste?
    
        Yard waste is grass, grass clippings, bushes, shrubs, and clippings 
    from bushes and shrubs. They come from residential, commercial/retail,

    solid waste.
        (2) The opacity limit is 35 percent (6-minute average) during the 
    startup period that is within the first 30 minutes of operation.
        (b) Except during malfunctions, the requirements of this subpart 
    apply at all times. Each malfunction must not exceed 3 hours.
    
    
    Sec. 60.1450  How must I monitor opacity for air curtain incinerators 
    that burn 100 percent yard waste?
    
        (a) Use EPA Reference Method 9 to determine compliance with the

    Equations
    
    
    Sec. 60.1460  What equations must I use?
    
        (a) Concentration correction to 7 percent oxygen. Correct any 
    pollutant concentration to 7 percent oxygen using the following 
    equation:
    
    C7% Cunc *(13.9) * (1/ (20.9 - CO2))
    
    Where:
    
    C7% = concentration corrected to 7 percent oxygen.
    Cunc = uncorrected pollutant concentration.
    CO2 = concentration of oxygen (%).
    
        (b) Percent reduction in potential mercury emissions. Calculate the 
    percent reduction in potential mercury emissions (%PHg) 
    using the following equation:
    
    %PHg = (Ei - Eo) * (100/Ei)
    
    Where:
    
    %PHg = percent reduction of potential mercury emissions
    Ei = mercury emission concentration as measured at the air 
    pollution control device inlet, corrected to 7 percent oxygen, dry 
    basis
    Eo = mercury emission concentration as measured at the air 
    pollution control device outlet, corrected to 7 percent oxygen, dry 
    basis
    
        (c) Percent reduction in potential hydrogen chloride emissions. 
    Calculate the percent reduction in potential hydrogen chloride 
    emissions (%PHC1) using the following equation:
    
    %PHC1 = (Ei - Eo) * (100/
    Ei)
    
    Where:
    
    %PHC1 = percent reduction of the potential hydrogen chloride 
    emissions
    Ei = hydrogen chloride emission concentration as measured at 
    the air pollution control device inlet, corrected to 7 percent oxygen, 
    dry basis
    Eo = hydrogen chloride emission concentration as measured at 
    the air pollution control device outlet, corrected to 7 percent oxygen, 
    dry basis
    
        (d) Capacity of a municipal waste combustion unit. For municipal 
    waste combustion units that can operate continuously for 24-hour 
    periods, calculate the municipal waste combustion units capacity based 
    on 24 hours of operation at the maximum charge rate. To determine the 
    maximum charge rate, use one of two methods:
        (1) For municipal waste combustion units with a design based on 
    heat input capacity, calculate the maximum charging rate based on this 
    maximum heat input capacity and one of two heating values:
        (i) If your municipal waste combustion unit combusts refuse-derived 
    fuel, use a heating value of 12,800 kilojoules per kilogram (5,500 
    British thermal units per pound).
        (ii) If your municipal waste combustion unit combusts municipal 
    solid waste, use a heating value of 10,500 kilojoules per kilogram 
    (4,500 British thermal units per pound).
        (2) For municipal waste combustion units with a design not based on 
    heat input capacity, use the maximum designed charging rate.
        (e) Capacity of a batch municipal waste combustion unit. Calculate 
    the capacity of a batch municipal waste combustion unit as the maximum 
    design amount of municipal solid waste they can charge per batch 
    multiplied by the maximum number of batches they can process in 24 
    hours. Calculate this maximum number of batches by dividing 24 by the 
    number of hours needed to process one batch. Retain fractional batches 
    in the calculation. For example, if one batch requires 16 hours, the 
    municipal waste combustion unit can combust 24/16, or 1.5 batches, in 
    24 hours.
        (f) Quarterly carbon usage. If you use activated carbon to comply 
    with the dioxin/furan or mercury limits, calculate the required 
    quarterly usage of carbon using the appropriate equation for plant 
    basis or unit basis:
        (1) Plant basis.
        [GRAPHIC] [TIFF OMITTED] TP30AU99.021
        
    Where:
    
    C = required quarterly carbon usage for the plant in kilograms (or 
    pounds).
    fi = required carbon feed rate for the municipal waste 
    combustion unit in kilograms (or pounds) per hour. This is the average 
    carbon feed rate during the most recent mercury or dioxin/furan stack 
    tests (whichever has a higher feed rate).
    hi = number of hours the municipal waste combustion unit was 
    in operation during the calendar quarter (hours).
    n = number of municipal waste combustion units, i, located at your 
    plant.
    
        (2) Unit basis.
    
    C = f * h
    
    Where:
    
        C = required quarterly carbon usage for the unit in kilograms (or 
    pounds).
        f = required carbon feed rate for the municipal waste combustion 
    unit in kilograms (or pounds) per hour. This is the average carbon feed 
    rate during the most recent mercury or dioxin/furan stack tests 
    (whichever has a higher feed rate).
        h = number of hours the municipal waste combustion unit was in 
    operation during the calendar quarter (hours).

    forcefully projecting a curtain of air across an open chamber or pit in 
    which combustion occurs. Incinerators of this type can be constructed 
    above or below ground and with or without refractory walls and floor.
    
    [[Page 47299]]
    
        Batch municipal waste combustion unit means a municipal waste 
    combustion unit designed so it cannot combust municipal solid waste 
    continuously 24 hours per day because the design does not allow waste 
    to be fed to the unit or ash to be removed during combustion.
        Calendar quarter means three consecutive months (nonoverlapping) 
    beginning on: January 1, April 1, July 1, or October 1.

    control of the operation of a municipal waste combustion unit. This 
    person is responsible for daily onsite supervision, technical 
    direction, management, and overall performance of the municipal waste 
    combustion unit.
        Class I units mean small municipal waste combustion units subject 
    to this subpart that are located at municipal waste combustion plants 
    with an aggregate plant capacity more than 250 tons per day of
