    SUPPLEMENTARY INFORMATION: Regulated entities. Entities that will 
    potentially be affected by these corrections are those that produce 
    acetal resins, acrylic and modacrylic fiber, hydrogen fluoride, and 
    polycarbonate and are major sources of hazardous air pollutants as 
    defined in section 112 of the Clean Air Act (Act). The regulated 
    categories and entities include the following:

                                   Producers of either acrylic fiber or
                                    modacrylic fiber synthetics composed of
                                    acrylonitrile (AN) units.

                                    acid. For the purpose of implementing
                                    the rule, HF production is not a process
                                    that produces gaseous HF for direct
                                    reaction with hydrated aluminum to form
                                    aluminum fluoride (i.e., the HF is not
                                    recovered as an intermediate or final
                                    product prior to reacting with the
                                    hydrated aluminum).

    a This table is not intended to be exhaustive, but rather provides a
      guide for readers regarding entities likely to be regulated by this
      action. This table lists the types of entities that we are now aware
      could potentially be regulated by this action. Other types of entities
      not listed in the table could also be regulated. To determine whether
      your facility, company, business, organization, etc., is regulated by
      this action, you should carefully examine the applicability criteria
      in Sec.  63.1104(a)(1), (b)(1), (c)(1), and (d)(1) of the rule. If you
      have questions regarding the applicability of this action to a
      particular entity, consult the person listed in the preceding FOR
      FURTHER INFORMATION CONTACT section.
    
    I. What Is the Background for the Corrections?
    
        On June 29, 1999 (64 FR 34854), we published the National Emission 
    Standards for Hazardous Air Pollutants: Generic MACT final rule which 
    promulgated standards for four major HAP source categories (i.e., 
    acetal resins production, acrylic and modacrylic fiber production, 
    hydrogen fluoride production, and polycarbonate production). The 
    proposal for the Generic MACT rule was published on October 14, 1998 
    (63 FR 55178), and given the size of the proposed rule, we allowed for 
    a 90-day public comment period even though we were under a May 15, 1999 
    court ordered deadline for the Administrator's signature of the final 
    rule. Because of the short time period between proposal and 
    promulgation and the many changes made to the proposal package, some 
    inadvertent errors were made. Today's action consists of editorial, 
    cross-reference, and clarifying corrections to the promulgated Generic 
    MACT rule published on June 29, 1999 (64 FR 34854). These corrections 
    will become effective immediately (without further rulemaking action) 
    on November 22, 1999. We have determined that it is unnecessary to 
    provide prior notice and opportunity to comment on these corrections. 
    In one case, we determined an opportunity for public comment is 
    warranted; we are proposing amendments to address this case in a 
    separate notice.
        Today's action corrects typographical, grammatical, and cross-
    reference errors. For example, as promulgated, 
    Sec. 63.998(a)(1)(iii)(A) incorrectly referred the reader to 
    Sec. 63.999(c)(8) for the requirement for an owner or operator to 
    report times and duration of all periods during which the flare or all 
    the pilot flames are absent. The correct citation for this requirement 
    is Sec. 63.999(c)(3) and today's action makes the necessary changes to 
    reflect the accurate citation. For another example, Sec. 63.1012(f) 
    incorrectly includes a citation with two repetitive paragraph 
    designations (i.e., Sec. 63.1003(e)(e)). Today's action corrects that 
    error by removing one of those paragraph designations (i.e., 
    Sec. 63.1003(e)).
        One of the corrections is in wording. We made an error in Table 2 
    to Sec. 63.1103(b)(3)(i), item 4, that could result in control 
    applicability errors. At promulgation, Table 2 to 
    Sec. 63.1103(b)(3)(i), item 4, erroneously required that an owner or 
    operator of a new or modified source that met specified criteria would 
    be subject to new source requirements. We should have specified that an 
    owner or operator of a new or reconstructed source, not modified 
    source, that met specified criteria would be subject to new source 
    requirements. We have corrected this error by replacing the word 
    ``modified'' with ``reconstructed.''
    
    II. What Are the Impacts Associated With the Corrections?
    
        This action consists of corrections and clarifications of our 
    intent at the time of
    
    [[Page 63703]]
    
    promulgation of 40 CFR part 63, subparts SS, TT, UU, WW, and YY, and 
    will not affect the estimated emissions reduction or the control costs 
    for the standards promulgated for AR, AMF, HF, and PC production source 
    categories on June 29, 1999 (64 FR 34854). These clarifications and 
    corrections should make it easier for owners and operators of affected 
    sources, and for local and State authorities, to understand and 
    implement the requirements found in these subparts.
    
    III. Administrative Requirements
    
    A. Paperwork Reduction Act
    
        The information collection requirements in this rule were submitted 
    for approval to the Office of Management and Budget (OMB) under the 
    Paperwork Reduction Act, 44 U.S.C. 3501, et seq. We submitted an 
    Information Collection Request (ICR) document (ICR No. 1871.02) and a 
    copy may be obtained from Sandy Farmer, OPPE Regulatory Information 
    Division, U.S. Environmental Protection Agency (2137), 401 M Street, 
    SW, Washington, DC 20460 or by calling (202) 260-2740. We 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 approved the information collection 
    requirements under the Generic MACT rule for the AR, AMF, HF, and PC 
    production source categories and assigned the OMB control number 2060-
    0420 to the ICR. This approval expires September 30, 2002.
        These corrections will not impact the information collection 
    estimates made previously for the Generic MACT consolidated rulemaking 
    package. Therefore, the ICR has not been revised.
    
    B. Executive Order 12866
    
        Under Executive Order 12866 (58 FR 51735, October 4, 1993), we must 
    determine whether the regulatory action is ``significant'' and 
    therefore subject to review by OMB and the requirements of the 
    Executive Order. The Order defines ``significant regulatory action'' as 
    one that is likely to result in a rule that may:
        (1) Have an annual effect on the economy of $100 million or more, 
    or adversely affect in a material way the economy, a sector of the 
    economy, productivity, competition, jobs, the environment, public 
    health or safety, or State, local, or tribal governments or 
    communities;
        (2) Create a serious inconsistency or otherwise interfere with an 
    action taken or planned by another agency;
        (3) Materially alter the budgetary impact of entitlements, grants, 
    user fees, or loan programs or the rights and obligations of recipients 
    thereof; or
        (4) Raise novel legal or policy issues arising out of legal 
    mandates, the President's priorities, or the principles set forth in 
    the Executive Order.
        Pursuant to the terms of Executive Order 12866, we have determined 
    that these correcting amendments do not qualify as a ``significant 
    regulatory action'' and, therefore, are not subject to review by OMB.
    
    C. Executive Order 13132 (Federalism)
    
        Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
    10, 1999), requires EPA to develop an accountable process to ensure 
    ``meaningful and timely input by State and local officials in the 
    development of regulatory policies that have federalism implications.'' 
    ``Policies that have federalism implications'' is defined in the 
    Executive Order to include regulations that have ``substantial direct 
    effects on the States, on the relationship between the national 
    government and the States, or on the distribution of power and 
    responsibilities among the various levels of government.'' Under 
    Executive Order 13132, EPA may not issue a regulation that has 
    federalism implications, that imposes substantial direct compliance 
    costs, and that is not required by statute, unless the Federal 
    government provides the funds necessary to pay the direct compliance 
    costs incurred by State and local governments, or EPA consults with 
    State and local officials early in the process of developing the 
    proposed regulation. EPA also may not issue a regulation that has 
    federalism implications and that preempts State law unless the Agency 
    consults with State and local officials early in the process of 
    developing the proposed regulation.
        If EPA complies by consulting, Executive Order 13132 requires EPA 
    to provide to the Office of Management and Budget (OMB), in a 
    separately identified section of the preamble to the rule, a federalism 
    summary impact statement (FSIS). The FSIS must include a description of 
    the extent of EPA's prior consultation with State and local officials, 
    a summary of the nature of their concerns and the agency's position 
    supporting the need to issue the regulation, and a statement of the 
    extent to which the concerns of State and local officials have been 
    met. Also, when EPA transmits a draft final rule with federalism 
    implications to OMB for review pursuant to Executive Order 12866, EPA 
    must include a certification from the agency's Federalism Official 
    stating that EPA has met the requirements of Executive Order 13132 in a 
    meaningful and timely manner.
        This final rule will not have substantial direct effects on the 
    States, on the relationship between the national government and the 
    States, or on the distribution of power and responsibilities among the 
    various levels of government, as specified in Executive Order 13132. 
    This rule has minimal direct affects on the 10 plants which are 
    impacted by this rule. This rule has even less impacts on States within 
    which the plants reside. Thus, the requirements of section 6 of the 
    Executive Order do not apply to this rule.
    
    D. Regulatory Flexibility Act/Small Business Regulatory Enforcement 
    Fairness Act of 1996
    
        The Regulatory Flexibility Act (RFA) of 1980 (5 U.S.C. 601, et 
    seq.), as amended by the Small Business Regulatory Enforcement Fairness 
    Act of 1996 (SBREFA), requires the EPA to give special consideration to 
    the effect of Federal regulations on small entities and to consider 
    regulatory options that might mitigate any such impacts. Small entities 
    include small businesses, small not-for-profit enterprises, and small 
    governmental jurisdictions.
        Today's corrections will not have a significant impact on a 
    substantial number of small entities because they clarify and make 
    corrections to the promulgated 40 CFR part 63, subparts SS, TT, UU, WW 
    and YY, and do not impose any additional regulatory requirements on 
    owners or operators of affected sources regulated by standards 
    promulgated on June 29, 1999 (64 FR 34854).
    
    E. Unfunded Mandates Reform Act
    
        Under section 202 of the Unfunded Mandates Reform Act (UMRA) of 
    1995, Pub. L. 104-4, we must prepare a budgetary impact statement to 
    accompany any proposed or final rule that includes a Federal mandate 
    that may result in estimated costs to State, local or tribal 
    governments, in the aggregate, or to the private sector, of $100 
    million or more in any 1 year. Section 203 requires us to establish a 
    plan for obtaining input from and informing, educating, and advising 
    any small governments that may be significantly or uniquely affected by 
    the rule.
        Under section 205 of UMRA, we must identify and consider a 
    reasonable number of regulatory alternatives before promulgating a rule 
    for which a budgetary impact statement must be
    
    [[Page 63704]]
    
    prepared. The Agency must select the least burdensome alternative from 
    those alternatives for State, local, and tribal governments and the 
    private sector that achieves the objectives of the rule, unless the 
    Agency explains why this alternative is not selected or unless the 
    selection of this alternative is inconsistent with law.
        Because these corrections do not include 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, we have not prepared a budgetary impact statement or specifically 
    addressed the selection of the least costly, most cost-effective, or 
    least burdensome alternative. In addition, because small governments 
    will not be significantly or uniquely affected by these correcting 
    amendments, we are not required to develop a plan with regard to small 
    governments. Therefore, the requirements of UMRA do not apply to this 
    action.
    
    G. Congressional Review Act
    
        The Congressional Review Act, 5 U.S.C. 801, et seq., as added by 
    the SBREFA of 1996, provides that before a rule may take effect, the 
    agency promulgating the rule must submit a rule report, which includes 
    a copy of the corrections, to each House of the Congress and to the 
    Comptroller General of the United States. Therefore, we will submit a 
    report containing these corrections and other required information to 
    the United States Senate, the United States House of Representatives, 
    and the Comptroller General of the United States prior to publication 
    in the Federal Register. A major rule cannot take effect until 60 days 
    after it is published in the Federal Register. This action does not 
    constitute a ``major rule'' as defined by 5 U.S.C. 804(2).
    
    H. National Technology Transfer and Advancement Act
    
        Under section 12(d) of the National Technology Transfer and 
    Advancement Act of 1995 (NTTAA), Pub. L. 104-113, section 12(d) (15 
    U.S.C. 272 note), we are directed to use voluntary consensus standards 
    instead of government-unique standards in its regulatory activities 
    unless to do so would be inconsistent with applicable law or otherwise 
    impractical. By doing so, the Act is intended to reduce the cost to the 
    private and public sectors.
        Voluntary consensus standards are technical standards (e.g., 
    materials specifications, test methods, sampling procedures, etc.) that 
    are developed or adopted by one or more voluntary consensus standards 
    bodies. Examples of organizations generally regarded as voluntary 
    consensus standards bodies include the American Society for Testing and 
    Materials (ASTM), International Organization for Standardization (IOS), 
    International Electrotechnical Commission (IEC), American Petroleum 
    Institute (API), National Fire Protection Association (NFPA), and the 
    Society of Automotive Engineers (SAE). The NTTAA requires that we 
    provide Congress, through OMB, explanations when we decide not to use 
    available and applicable voluntary consensus standards.
        As part of a larger effort, we are undertaking a project to cross-
    reference existing voluntary consensus standards in testing, sampling, 
    and analysis, with current and future EPA test methods. When completed, 
    this project will assist us in identifying potentially applicable 
    voluntary consensus standards that can then be evaluated for 
    equivalency and applicability in determining compliance with future 
    regulations.
        This action does not require the use of any new technical 
    standards, therefore section 12(d) does not apply.
    
    I. Executive Order 13045
    
        Executive Order 13045, entitled Protection of Children from 
    Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 
    1997), applies to any rule that we determine (1) is economically 
    significant as defined under Executive Order 12866, and (2) the 
    environmental health or safety risk addressed by the rule has a 
    disproportionate effect on children. If the regulatory action meets 
    both criteria, we 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 us.
        These corrections are not subject to Executive Order 13045 because 
    they do not constitute an economically significant regulatory action as 
    defined by Executive Order 12866 and because they do not establish an 
    environmental standard intended to mitigate health or safety risks.
    
    J. Executive Order 13084
    
        Under Executive Order 13084, we 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 
    cost incurred by the tribal governments, or we consult with those 
    governments. Under Executive Order 13084, if we comply by consulting, 
    we are required to provide to OMB, in a separately identified section 
    of the preamble to the rule, a description of the extent of our 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, we are required 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.''
        Today's corrections do not impose any duties or compliance costs on 
    Indian tribal governments. Further, the corrections provided herein do 
    not significantly alter the control standards imposed by subparts SS, 
    TT, UU, WW, and YY, including any that may affect communities of Indian 
    tribal governments. Hence, today's action does not significantly or 
    uniquely affect the communities of Indian tribal governments. 
    Accordingly, the requirements of section 3(b) of Executive Order 13084 
    do not apply to this action.

    a Combined vent streams shall use the applicability determination
      procedures and methods for process vents from continuous unit
      operations (Sec.  63.1104).
    b The TRE equation coefficients for halogenated streams (table 7 of this
      subpart) shall be used to calculate the TRE index value.
    c The TRE is determined according to the procedures specified in Sec.
      63.1104(j). If a dryer is manifolded with such vents, and the vent is
      routed to a recovery, recapture, or combustion device, then the TRE
      index value for the vent must be calculated based on the properties of
      the vent stream (including the contributions of the dryer). If a dryer
      is manifolded with other vents and not routed to a recovery,
      recapture, or combustion device, then the TRE index value must be
      calculated excluding the contributions of the dryer. The TRE index
      value for the dryer must be calculated separately in this case.
    d The mass emission rate of halogen atoms contained in organic compounds
      is determined according to the procedures specified in Sec.
      63.1104(i).
    e The weight-percent organic HAP is determined for equipment according
      to procedures specified in Sec.  63.1107.

        (1) TRE index value equation. The equation for calculating the TRE 
    index value is Equation 5:
    
    TRE = 1/EHAP*[A+B(QS)+ C(HT)+ 
    D(ETOC)]  [Eq. 5]
    
    Where:
    
    TRE = TRE index value.
    A, B, C, D = Coefficients presented in table 1 of this section.
    EHAP = Emission rate of total organic HAP, kilograms per 
    hour, as calculated according to paragraph (h) or (k) of this section.
    QS = process vent flow rate, standard cubic meters per 
    minute, at a standard temperature of 20  deg.C, as calculated according 
    to paragraph (f) or (k) of this section.
    HT = process vent net heating value, megaJoules per standard 
    cubic meter, as calculated according to paragraph (g) or (k) of this 
    section.
    ETOC = Emission rate of TOC (minus methane and ethane), 
    kilograms per hour, as calculated according to paragraph (h) or (k) of 
    this section.

        (1) * * * For each excursion except for excused excursions (as 
    described in Sec. 63.998(b)(6)(ii)), and as provided for in paragraph 
    (b)(2) of this section the owner or operator shall be deemed to have 
    failed to have applied the control in a manner that achieves the 
    required operating conditions.
        (2) Parameter monitoring: Excursions. An excursion is not a 
    violation in cases where continuous monitoring is required and the 
    excursion does not count toward the number of excused excursions (as 
    described in Sec. 63.998(b)(6)(ii)), if the conditions of paragraph 
    (b)(2)(i) or (ii) of this section are met. * * *
