    National Emission Standards for Hazardous Air Pollutants; 
    Revision of Initial List of Categories of Sources and Schedule for 
    Standards Under Sections 112(c) and (e) of the Clean Air Act Amendments 
    of 1990
    
    AGENCY: Environmental Protection Agency (EPA).
    
    ACTION: Notice of revisions to initial list of categories of major and 
    area sources, and revisions to promulgation schedule for standards.
    
    -----------------------------------------------------------------------
    
    SUMMARY: This notice publishes revisions made or which have been 
    proposed to the initial list of categories of sources of hazardous air 
    pollutants (HAP), published in the Federal Register on July 16, 1992 
    (57 FR 31576), and to the schedule for the promulgation of emission 
    standards, which was published on December 3, 1993 (58 FR 63941) and 
    subsequently corrected on March 4, 1994 (59 FR 10461).
        Today's notice meets the requirement in Section 112(c)(1) to 
    publish from time to time a list of all categories of sources, 
    reflecting revisions since the initial list was published. Several of 
    the revisions identified in today's notice have already been published 
    in actions associated with listing and promulgating emission standards 
    for individual source categories, and public comment has already been 
    taken in the context of those actions. Some of the revisions in today's 
    notice have not been reflected in any previous notices, and are being 
    taken without public comment on the Administrator's own motion. Such 
    revisions are deemed by EPA to be without need for public comment, 
    based on the nature of the actions. Other revisions have been only 
    proposed as of today's date, but are reflected nevertheless to be 
    inclusive of all list and schedule actions of probable interest to the 
    reader.
    
    EFFECTIVE DATE: June 4, 1996.
    
    ADDRESSES: Relevant information can be found in the two Federal 
    Register notices cited above in the SUMMARY section of this notice.
        Docket: Docket No. A-90-49, containing supporting information used 
    in development of this notice, is available for public inspection and 
    copying between 8 a.m. and 5:30 p.m., Monday through Friday, at the 
    EPA's Air and Radiation Docket and Information Center, Waterside Mall, 
    room M-1500, first floor, 401 M Street, SW, Washington, D. C. 20460, or 
    by calling (202) 260-7548 or 260-7549. A reasonable fee may be charged 
    for copying.

    SUPPLEMENTARY INFORMATION
    
    I. Background
    
        The Clean Air Act Amendments of 1990 [Pub. L. 101-549] require, 
    under the revisions to Section 112, that the Agency list and promulgate 
    national emission standards for hazardous air pollutants (NESHAP) in 
    order to control, reduce, or otherwise limit the emissions of HAP from 
    categories of major and area sources. Pursuant to the various specific 
    listing requirements in Section 112(c), the Agency published on July 
    16, 1992 (57 FR 31576) an initial list of 174 categories of major and 
    area sources that would be henceforth subject to emission standards. 
    Following this listing, pursuant to requirements in Section 112(e), on 
    December 3, 1993 (58 FR 63941) the Agency published a schedule for the 
    promulgation of emission standards for each of the 174 listed source 
    categories. The reader is directed to these two notices for information 
    relating to development of the initial list and schedule.
        There have been specific notices since the initial list and 
    schedule that have revised the list and schedule in the context of 
    actions relating to individual source categories. For example, on 
    November 12, 1993 (58 FR 60021), the Agency listed marine vessel 
    loading operations as a category of major sources, with standards to be 
    promulgated, pursuant to Section 112(c)(5), by the year 2000. As 
    another example, on September 8, 1994 (59 FR 46339), the Agency 
    promulgated standards for HAP emissions for industrial process cooling 
    towers. This latter action did not revise the list or schedule, per se, 
    but specifically delineated rule applicability by defining the affected 
    sources within the listed category. The Agency believes that defining 
    rule applicability and affected sources as part of standard setting 
    constitutes an important aspect of list revision. As was stated in the 
    original listing notice (57 FR 31576):
    
    the Agency recognizes that these descriptions [in the initial list], 
    like the list itself, may be revised from time to time as better 
    information becomes available. The Agency intends to revise these 
    descriptions as part of the process of establishing standards for 
    each category. Ultimately, a definition of each listed category, or 
    subsequently listed subcategories, will be incorporated in each rule 
    establishing a NESHAP for a category.
    
        Various other Agency actions may trigger the need for list and/or 
    schedule revisions. Included actions are:
    
    --The Administrator is obligated to list any category of major sources. 
    Today's notice is listing seven
    
    [[Page 28198]]
    
    categories of major sources for which it did not have prior evidence 
    that at least one major source was present within the category. Two of 
    the seven additions were effected through previous Federal Register 
    notices, and are thereby reflected in today's notice. When a category 
    is added to the list after the initial listing, pursuant to Sections 
    112(c)(1) and (3), emission standards must be scheduled by November 15, 
    2000, or within 2 years after the date of listing, whichever is later, 
    to meet the requirements of Section 112(c)(5).
    --The Agency may list categories of area sources pursuant to a number 
    of authorities in Section 112. One area source category-- secondary 
    lead smelting--has been added to the list since the initial listing 
    notice as part of a final regulatory action, and is reflected in 
    today's list.
    --The Administrator may delete categories of sources on its own motion 
    or on petition. Five source categories which were previously believed 
    to be major source categories are being deleted from the list on the 
    Administrator's own motion in today's notice. This notice refers to one 
    area source category that has been deleted from the list under a 
    separate action. None of these deletions is as a result of petition.
    --The Agency may revise the list to delineate the applicability of 
    ``case-by-case'' emission standards pursuant to Section 112(j), in 
    instances where the Agency desires to delimit the affected sources 
    because it may not establish a Federal emission standard by the 
    deadline in the regulatory schedule for standards. No such revision is 
    made or reflected in today's notice.
    --The Agency may revise the regulatory schedule for standards 
    associated with a listed source category, heeding the limitations in 
    Section 112 (discussed in 58 FR 63941). For example, the regulatory 
    schedule for one source category--dodecanedioic acid production--is, in 
    effect, moved forward in time, from the year 2000 to 1992, following 
    the determination to incorporate this category within the definition of 
    the synthetic organic chemical manufacturing source category (see 59 FR 
    19402). Today's notice specifies two such actions involving subsumption 
    of previously listed source categories, or segments of source 
    categories, within another category, and the corresponding change in 
    regulatory schedules. In each case, however, the action is not being 
    effected by today's notice, but rather has been effected (or proposed) 
    within other notices for which public comment has been (or is being) 
    taken.
    --Other ``housekeeping'' measures. After investigation by the Agency, 
    it has been determined that the titles or descriptions of some 
    categories of sources can be amended to clarify applicability for the 
    ensuing emission standard, and other categories can be included under a 
    different, more appropriate industry group. In today's notice, two 
    categories of sources are renamed, three categories are reassigned to 
    different industry groups, and no categories are redefined (although in 
    most instances, descriptions of source categories have been refined 
    upon determining applicability at promulgation of the rule).
        Section 112(e)(4) states that, notwithstanding Section 307 of the 
    Act, no action of the Administrator listing a source category or 
    subcategory under Section 112(c) shall be a final Agency action subject 
    to judicial review, except that any such action may be reviewed under 
    Section 307 when the Administrator issues emission standards for such 
    pollutant or category. Therefore, today's list is not a final Agency 
    action and is not subject to judicial review.
        Prior to issuance of the initial source category list under Section 
    112(c)(1), the EPA published a draft initial list for public comment 
    (56 FR 28548; June 21, 1991). Although EPA was not required to take 
    public comment on the initial source category list, it believed it was 
    useful to solicit input on a number of issues related to the list. 
    Indeed, in most instances, even where there is no statutory requirement 
    to take comment, EPA solicits public comment on actions it is 
    contemplating. The EPA has, however, decided that it is unnecessary to 
    solicit additional public comment on the revisions reflected in today's 
    notice because interested parties have already had, or will have in the 
    future, the opportunity to provide comments on many of the revisions in 
    the context of individual actions relating to proposing and 
    promulgating emissions standards.
    
    II. Description of Individual List and Schedule Revisions
    
        The revised source category list and regulatory schedule, 
    reflecting all actions (with the exception of proposed actions) up to 
    today's date, is presented in Table 1. This table incorporates the 
    entire listing of source categories listed to this date, including 
    those listed initially as well as those listed subsequently. Table 1 
    also includes the updated schedule for establishing emission standards 
    under Section 112 for the listed categories, including actual rule 
    proposal or promulgation Federal Register citations. Table 1 is 
    formatted so that the reader can at once see all categories of major 
    and area sources that have been listed to date, the associated schedule 
    for standards, and any revisions effected by or reflected in today's 
    notice. Source categories and/or schedules for standards in Table 1 
    that are revised from the initial July 16, 1992 listing and December 3, 
    1993 schedule notices are footnoted or clearly marked for ease in 
    discerning where revisions have been made.
    
    A. Addition of Categories of Major Sources
    
        In response to new information, today's notice reflects the listing 
    of the following categories of major sources: Carbon Black Production, 
    Ethylene Processes, Flexible Polyurethane Foam Fabrication Operations, 
    Friction Products Manufacturing, Leather Tanning and Finishing 
    Operations, Marine Vessel Loading Operations, and Nitrile Resins 
    Production. Pursuant to Section 112(c)(5), each of the newly listed 
    categories of sources is scheduled for standards promulgation by 
    November 15, 2000. Descriptions of these source categories can be found 
    in Section II.I of today's notice. The reader is referred to Docket No. 
    A-90-49, Section VI-B, for more information supporting the listing of 
    the above seven source categories.
    
    B. Addition of Categories of Area Sources
    
        The various authorities to list and regulate area source categories 
    under Section 112 are all discretionary and/or require some sort of 
    finding or determination by the Administrator. The Agency believes that 
    any such area source listing action is therefore subject to public 
    comment and is consequently not being taken in today's notice. Instead, 
    todays notice merely reflects any such findings or determinations.
        Today's notice reflects a June 23, 1995 notice (60 FR 32587) 
    finalizing the addition of secondary lead smelters as an area source 
    category. Accompanying this notice is a finding of threat of adverse 
    effects based on seven smelters that the Agency believes fit the 
    definition of an area source.
    
    C. Delineation of Standard Applicability and Affected Sources Through 
    Standard Promulgation
    
        Emission standards have been promulgated under Section 112 for 
    several source categories since the initial source category list and 
    schedule were published. Table 1 identifies the
    
    [[Page 28199]]
    
    Federal Register cite for each of these notices. These actions are 
    cited in today's notice because they revise the list in that they 
    delineate rule applicability by defining the affected sources within 
    the listed category.
    
    D. Proposed Delineation of Standard Applicability and Affected Sources 
    Through Standard Proposal
    
        Emission standards have been proposed under Section 112 for several 
    source categories since the initial source category list and schedule 
    were published. These actions are cited in today's notice principally 
    insofar as they propose to revise the list in that they will delineate 
    rule applicability by defining the affected sources within the listed 
    category. The reader is referred to Table 1 to obtain the Federal 
    Register citations for these categories of sources.
    
    E. Name Changes for Listed Source Categories
    
        The Agency has determined that the names of some source categories 
    are inappropriate, and is hereby changing them. The applicable 
    categories are:
    1. Solid Waste Treatment, Storage and Disposal Facilities (TSDF)
        On October 13, 1994 (59 FR 51913), the Agency proposed emission 
    standards for the Solid Waste TSDF source category and changed its 
    title to ``Off-Site Waste and Recovery Operations.'' As discussed in 
    that notice, this change was considered appropriate for two reasons. 
    First, it will help avoid confusion with the terms ``solid waste'' and 
    ``treatment, storage, and disposal facilities.'' These terms have 
    specific meanings within the context of statutory and regulatory 
    requirements in existing rules established under authority of the 
    Resource Conservation and Recovery Act (RCRA), and this source category 
    would not include those facilities defined as solid waste treatment, 
    storage, and disposal facilities by the RCRA. Second, the name change 
    will better distinguish among the types of sources that will be subject 
    to the emission standard for this source category, rather than another 
    listed source category. Facilities within other source categories may 
    generate waste as a result of their own production activities, and may 
    elect to treat, store, dispose of, or recycle this waste on the same 
    site. Emissions from these waste operations will be addressed along 
    with the other emission points within the specific source category. 
    This source category specifically addresses only activities that manage 
    wastes received from off-site operations.
    2. Butadiene Dimers Production
        This major source category, under the ``miscellaneous processes'' 
    grouping on the initial list, is being changed in name to 
    ``tetrahydrobenzaldehyde production,'' under the same industrial 
    process grouping. The Agency has determined, based on comments, that 
    the butadiene dimer is produced by only one facility in the nation, as 
    a waste product from the tetrahydrobenzaldehyde process. The specific 
    dimer is 1,4-vinyl cyclohexane. Tetrahydrobenzaldehyde is the only 
    identified chemical under the butadiene dimers source category in the 
    initial list; therefore, changing the name of the source category will 
    not change the applicability of the subsequent emission standard or the 
    affected sources. This change will merely identify the correct chemical 
    the Agency intended to regulate pursuant to the initial list.
    
    F. Inclusion of Listed Source Categories Under Different Industry 
    Groups
    
        The Agency has determined that three source categories were 
    previously categorized under inappropriate industry groups and is 
    hereby moving these categories to more appropriate industrial groups 
    for purposes of correctness. In each case, the movement of the source 
    category will have no effect on the development or the promulgation 
    date of the NESHAP.
    1. Butadiene Furfural Cotrimer (R-11) Production
        This category was improperly listed in the initial list under the 
    ``polymer and resins'' industry group. Butadiene furfural cotrimer is 
    an insecticide that is commonly used as a delousing agent for cows. It 
    is therefore appropriate to move this source category to the 
    ``agricultural chemicals'' industry group.
    2. Polyether Polyols Production
        This category was improperly listed in the initial list under the 
    ``miscellaneous'' industry group. Polyether polyols are defined as 
    addition polymers of cyclic ethers, which include a variety of end use 
    products ranging from low molecular weight polyglycols to high 
    molecular weight resins. It is therefore appropriate to move this 
    source category to the ``polymers and resins production'' industry 
    group.
    3. Quaternary Ammonium Compounds Production
        This category is more appropriately listed under the heading 
    ``organic chemicals production,'' rather than the ``inorganic chemicals 
    production'' industry group. This compound is clearly an organic 
    chemical; thus, the previous determination to include this as an 
    inorganic chemical production was an error.
    
    G. Subsumption of Listed Source Categories (or some affected sources 
    within) Under Other Listed Source Categories
    
    1. The Synthetic Organic Chemical Manufacturing Source Category and 
    Dodecanedioic Acid Production
        The source category ``Dodecanedioic Acid Production'' is being 
    removed from the list of major source categories because the production 
    of this chemical is being regulated under the Hazardous Organic NESHAP 
    (HON) (59 FR 19402; April 22, 1994). Based on public comment, the 
    Agency determined that dodecanedioic acid (DDDA) production is more 
    appropriately regulated as part of the synthetic organic chemical 
    manufacturing source category rather than as part of a separate source 
    category. Only one facility in the United States has been identified as 
    manufacturing DDDA, and much of the equipment used in the DDDA 
    production process is the same equipment used to manufacture 
    adiponitrile, which is included in the list of Synthetic Organic 
    Chemical Manufacturing Industry (SOCMI) chemicals regulated by the HON. 
    Thus, this chemical has been offically added to the list of SOCMI 
    chemicals subject to the HON.
    2. Phthalate Plasticizers Production and the Synthetic Organic Chemical 
    Manufacturing Source Category
        In the finalized HON, the EPA re-evaluated several chemicals, 
    including phthalate esters, which some commenters had claimed were not 
    SOCMI chemicals. The EPA agreed that phthalate esters were chemicals 
    used primarily as plasticizers, not as building blocks for other 
    chemical manufacturing. Thus, phthalate esters were removed from the 
    list of SOCMI chemicals covered under the HON. The Agency intends to 
    regulate the production of these esters under the separate source 
    category entitled ``phthalate plasticizers production,'' under the 
    miscellaneous processes industry group. The affected chemicals are 
    butyl benzyl phthalate, diallyl phthalate, dibutoxy ethyl phthalate, 
    diethyl phthalate, diisodecyl phthalate, diisooctyl phthalate, dimethyl 
    phthalate, di(2-methoxyethyl) phthalate, and lead phthalate.
    
    [[Page 28200]]
    
    H. Deletion of Source Categories on the Administrator's Own Motion
    
        In today's notice, the EPA is deleting five major source categories 
    on the Administrator's own motion. The principal rationale for deletion 
    of these categories is that available data no longer support the 
    determination that any major sources are present in each category. As 
    articulated in the initial list notice (57 FR 31576), the Agency's 
    intent in listing categories of major sources is one of ``only 
    including categories of major sources where there was reasonable 
    certainty that at least one stationary source in the category is a 
    major source or where sources in the category are commonly located on 
    the premises of major sources.'' In addition, one area source 
    category--asbestos processing--has been delisted under a separate 
    action; the Agency compiled newer information which no longer supported 
    the finding of threat of adverse effect on which the initial listing 
    was based.
        The Agency is not invoking the authority within Section 112(c)(9) 
    for deleting source categories. Under Section 112(c)(9)(B), the EPA may 
    delete a category of major or area sources from the list, based on 
    petition of any person or on the Administrator's own motion, upon a 
    determination that: (1) In the case of sources that emit HAP that may 
    result in cancer, no source in the category (or group of sources in the 
    case of area sources) emits HAP in quantities that may cause lifetime 
    cancer risk greater than one chance in one million to the most exposed 
    individual; or, (2) in the case of sources that emit HAP that may 
    result in non-cancer adverse health effects or adverse environmental 
    effects, emissions from no source in the category (or group of sources 
    in the case of area sources) exceed a level adequate to protect public 
    health with an ample margin of safety and no adverse environmental 
    effects will result. Instead, in today's notice, the Agency is simply 
    contending that the data originally used for listing were erroneous, 
    and that, based on newer data, the original listings are not warranted.
        For the five major source categories deleted in today's notice, no 
    action is taken to list area sources within the same category. Any such 
    action would be taken (and comment requested) within the context of 
    other actions pursuant to the various authorities under Section 112 for 
    listing area source categories. The Agency has various authorities for 
    listing and regulating area source categories under Section 112, most 
    notably: it can make a finding of threat of adverse effect to human 
    health or the environment warranting regulation, under Section 
    112(c)(3); it can list categories of area sources emitting the seven 
    specific pollutants, under Section 112(c)(6); or it can list categories 
    of area sources emitting certain hazardous air pollutants per the 
    criteria of the area source program, under Section 112(k). The Agency 
    will examine area sources in the context of programs underway to 
    implement these various authorities, and list and regulate specific 
    area sources, as appropriate to meet the relevant requirements in the 
    Act. The Agency intends to solicit comment on any future action or 
    strategy specifically proposing to list and regulate particular area 
    source categories under Section 112.
        The following does not include the categories of sources which are 
    being deleted from the list by way of subsumption into other listed 
    categories. See Section II.G of this notice for information on these 
    categories.
    1. Asbestos Processing
        The area source category of asbestos processing was included on the 
    initial list, accompanied by a finding of threat of adverse effects to 
    human health. The reader is referred to the original list notice (57 FR 
    31576) for details of this finding.
        During development of the NESHAP for asbestos processing, the 
    Agency determined that the finding of adverse effects was based on 
    information which no longer applies to the asbestos processing 
    industry. Consequently, the asbestos processing source category has 
    been deleted from the source category list. For further information 
    regarding this delisting, the reader is referred to 60 FR 61550, which 
    was published on November 30, 1995.
    2. Chromium Chemicals Manufacturing
        The EPA is removing chromium chemicals manufacturing from the list 
    of categories of major sources. The EPA has determined that this 
    category contains no major sources.
        There are only two chromium chemicals manufacturing facilities in 
    the United States. Chromium compounds is the only HAP emitted from 
    these facilities. Worst case estimates of potential emissions on a 
    chromium compound basis, considering both hexavalent and trivalent 
    forms, were compiled for each facility based on maximum production 
    capacity and actual measured emissions from all stacks and vents. The 
    resultant estimate of potential HAP emissions for each facility is 
    between 6.0 and 6.5 tons per year (tpy), which is clearly below the 
    major source threshold level.
        Considering the carcinogenic potency of the chromium compounds 
    emitted, especially those in the hexavalent form, a quantitative risk 
    assessment was conducted by EPA to determine if regulation of area 
    sources would be warranted. In making the area source finding, the 
    Agency considered factors such as the number of sources in the 
    category, the quantity of HAP emissions from individual sources and 
    category-wide, the toxicity of the HAP emissions, and the potential for 
    individual and population exposures and risks. Population risks are 
    expressed in terms of annual incidence which is the total number of 
    cancer cases expected per year within the exposed population. In 
    contrast, individual risks are expressed in terms of maximum individual 
    ``lifetime'' risks (MIR) which is an indicator of the probability of 
    contracting cancer due to continuous exposure over a lifetime to the 
    maximum, modeled, long-term concentration of a HAP discharged from a 
    source.
        Results of the quantitative risk assessment shows annual incidence 
    attributable to both plants to be less than 0.01 case per year. The 
    calculated MIR for both plants ranged from 3 to 7 chances in 100,000. 
    About 200,000 persons are exposed to individual risks greater than 1 in 
    1 million. No persons are exposed to individual risks greater than 1 in 
    10,000.
        Based on the results of the quantitative risk assessment and the 
    fact that there exists limited opportunities for additional HAP 
    reductions, due to the relatively high levels of control already 
    evident at each source, the EPA believes that an area source finding 
    for the chromium chemicals manufacturing source category is not 
    warranted.
    3. Lead Acid Battery Manufacturing
        The EPA is removing lead acid battery manufacturing from the list 
    of major source categories. Surveys conducted on this category indicate 
    there are no major sources currently operating.
        The lead acid battery manufacturing source category includes 84 
    facilities. Lead compounds are the primary HAP of concern. A survey of 
    existing facilities was conducted to determine annual HAP emissions. 
    Respondents to the survey represent more than 90 percent of the total 
    lead acid battery production. The highest lead compound emission rate 
    reported by a facility was 2.8 tpy.
        In addition, all existing facilities are currently subject to the 
    new source performance standards (NSPS) for lead
    
    [[Page 28201]]
    
    acid battery manufacturing plants. Any new facilities will also be 
    subject to these standards. The limits from the NSPS were combined with 
    model plant parameters to determine the emission levels from large 
    facilities. This analysis indicated that a large facility would emit a 
    maximum of 5 tpy of lead compounds.
        The Toxic Release Information System (TRIS) data was reviewed for 
    the years 1991 and 1992 to determine emission levels of HAP other than 
    lead compounds. Of the 84 plants, the TRIS identified two battery 
    manufacturing plants as potential major sources of organic HAP. 
    However, upon contacting these plants to obtain current process and 
    emissions information, the EPA determined that the TRIS information was 
    no longer applicable. Specifically, one facility had altered part of 
    its process and had not been a major source since 1992, and the other 
    plant had been originally misclassified in the TRIS and was not 
    actually a lead acid battery manufacturer. Based on this information, 
    the EPA concludes that there are no major sources in the lead acid 
    battery manufacturing source category.
    4. & 5. Non-Stainless Steel Manufacturing--Electric Arc Furnace (EAF) 
    Operation, Stainless Steel Manufacturing--EAF Operation
        The EPA is removing the non-stainless and stainless steel electric 
    arc furnace (EAF) operation categories from the list of major source 
    categories. These operations are being removed since there are no 
    existing facilities which qualify as a major source.
        Arsenic, antimony, beryllium, cadmium, chromium, cobalt, lead, 
    manganese, mercury, nickel, and selenium are believed to be the only 
    HAP emitted from the EAF source categories. None of the existing 
    facilities emit any of these HAP in sufficient quantities to meet the 
    major source definition. Total facility emission estimates for the EAF 
    source categories were calculated by combining actual stack emission 
    data with ``worst case'' fugitive emission estimates. The results of 
    this analysis indicated these facilities would emit about one-half of 
    the amount of HAP which would classify them as major sources. In 
    addition, existing facilities are already subject to the NSPS for EAF 
    operations which regulate the air pollution control device outlet 
    concentration and visible emissions from the EAF meltshop. Any new 
    facilities would also be subject to the NSPS.
    6. Wood Treatment
        The EPA is removing the wood treatment category from the list of 
    major source categories. Wood treatment is being removed because EPA 
    has determined there are no existing facilities which qualify as a 
    major source.
        Naphthalene, benzene, toluene, formaldehyde, pentachloro-phenol, 
    arsenic compounds, and chromium compounds are the primary HAP emitted 
    from wood treatment facilities that are of potential concern. None of 
    the existing facilities emit any of these HAP in sufficient quantities 
    to meet the major source definition. Chromium and arsenic compounds are 
    emitted in quantities less than 100 pounds per year. Pentachlorophenol 
    emissions from a ``worst case'' treatment facility were estimated to be 
    less than one tpy.
        For creosote treatment facilities, emissions test results, combined 
    with ``worst case'' estimates of fugitive emissions, were used to 
    determine total emissions of creosote components. Emissions of 
    individual HAP were well under 10 tpy, and total HAP emissions were 
    significantly less than 25 tpy. Therefore, the EPA is deleting this 
    category from the source category list after concluding that there are 
    no major sources in the category.
    
    I. Descriptions of Newly Added Source Categories
    
        The following presents descriptions for source categories that have 
    been added to the list since publication of the initial list of source 
    categories, either through today's notice or through previous actions. 
    For general descriptions of other categories previously established and 
    listed in Table 1, the reader is referred to Docket No. A-90-49, Item 
    No. IV-A-55 (EPA-450/3-91-030, entitled ``Documentation for Developing 
    the Initial Source Category List''). For subsequent changes to 
    descriptions of source categories for which a rule has been 
    promulgated, the reader is advised to consult Table 1 for the citation 
    of the Federal Register notice which will include the amended 
    definition and corresponding rule applicability.
    1. Carbon Black Manufacturing
        This source category includes facilities that manufacture carbon 
    black using the channel, thermal, or furnace process. The primary 
    emission point for the process offgases from the main filter unit. HAP 
    emitted include carbonyl sulfide, carbon disulfide, and hydrogen 
    cyanide. Carbon black is used to color and strengthen industrial rubber 
    products, primarily automotive tires, belts, and hoses. Other major end 
    uses for carbon black include specialty black coloring used in toner 
    cartridges for copying machines and colorants in inks, paints, and 
    vinyl plastic.
    2. Ethylene Processes
        The finalized HON excluded ethylene processes from applicability 
    under that standard and defined the scope of an ethylene process unit 
    as follows:
        ``Ethylene processes'' includes any chemical manufacturing process 
    unit in which ethylene and/or propylene are produced by separation from 
    petroleum refining process streams or by subjecting hydrocarbons to 
    high temperatures in the presence of steam. The ethylene process unit 
    includes the separation of ethylene and/or propylene from associated 
    streams such as a C4 product, pyrolysis gasoline, and pyrolysis 
    fuel oil. The ethylene process does not include the manufacture of 
    SOCMI chemicals such as the production of butadiene from the C4 
    stream and aromatics from pyrolysis gasoline.
    3. Flexible Polyurethane Foam Fabrication Operations
        The flexible polyurethane foam fabrication operations source 
    category includes facilities engaged in cutting, gluing, and/or 
    laminating pieces of flexible polyurethane foam. This includes 
    fabrication operations which are located at the sites of foam 
    production plants as well as those which are located off-site of foam 
    plants. Emissions from foam fabrication primarily result from the use 
    of HAP-based adhesives in the gluing process. Methylene chloride is 
    currently the most frequently used HAP in adhesives.
    4. Friction Products Manufacturing
        This source category includes facilities and processes that 
    manufacture or remanufacture friction products including automobile 
    brake linings and disc pads. HAP are emitted from solvents added during 
    the proportioning and mixing of raw materials and the solvents 
    contained in the adhesives used to bond the linings to the brake shoes. 
    Most HAP emissions occur during heated processes such as curing, 
    bonding and debonding processes. Pollutants from friction products 
    facilities include phenol, toluene, methyl chloroform and 
    methylethylketone.
    5. Leather Tanning and Finishing Operations
        The leather tanning and finishing source category includes 
    facilities and processes that use chemical and
    
    [[Page 28202]]
    
    mechanical processes to produce leather having hundreds of different 
    finished characteristics. Leather tanning involves primarily wet 
    chemical processes that produce a stable, usable product. Leather 
    finishing involves a number of conditioning and enhancement processes 
    that give tanned leather distinctive and desirable qualities required 
    by end users of the material. Sources of HAP emissions in the leather 
    tanning and finishing processes include leather finishing operations, 
    waterproofing operations, solvent degreasing operations, and 
    miscellaneous fugitive sources. HAP from this category include toluene, 
    xylene, glycol ethers, methyl isobutyl ketone, and methyl ethyl ketone.
    6. Marine Vessel Loading Operations
        This source category includes marine terminals which emit HAP from 
    the direct loading and unloading of bulk liquids from marine vessels. 
    This category does not include emissions from offshore vessel-to-vessel 
    bulk liquid transfer operations (i.e., lightering operations).
        The reader is also referred to a September 19, 1995 notice (60 FR 
    48399) for specific applicability of the marine vessel loading 
    operations source category.
    7. Nitrile Resins Production
        The nitrile resins production source category includes any facility 
    which polymerizes acrylonitrile, methyl acrylate, and butadiene latex 
    using an emulsion process.
        The reader is also referred to a March 29, 1995 notice (60 FR 
    16090) for proposed applicability of the nitrile resins production 
    source category.
    8. Secondary Lead Smelting (Category of Area Sources)
        The reader is referred to a June 23, 1995 notice (60 FR 32587) for 
    specific applicability of the secondary lead smelting area source 
    category.
    
    III. Administrative Requirements
    
    A. Docket
    
        The docket for this regulatory action is A-90-49. The docket is an 
    organized and complete file of all the information submitted to or 
    otherwise considered by the Agency in the development of this revised 
    list of categories of sources and revised schedule for standards. The 
    principal purpose of this docket is to allow interested parties to 
    identify and locate documents that serve as a record of the process 
    engaged in by the Agency to publish today's revision to the initial 
    list and schedule. The docket is available for public inspection at the 
    EPA's Air and Radiation Docket and Information Center, which is listed 
    in the ADDRESSES section of this notice.
    
    B. Regulatory Requirements
    
    1. General
        Today's notice is not a rule; it is essentially a housekeeping or 
    maintenance activity which does not impose regulatory requirements or 
    costs. Therefore, the EPA has not prepared an assessment of the 
    potential costs and benefits pursuant to Executive Order 12866, nor an 
    economic impact analysis pursuant to Section 317, nor a regulatory 
    flexibility analysis pursuant to the Regulatory Flexibility Act (Pub. 
    L. 96-354, September 19, 1980), nor a budgetary impact statement 
    pursuant to the Unfunded Mandates Act of 1995. Also, this notice does 
    not contain any information collection requirements and, therefore, is 
    not subject to the Paperwork Reduction Act, 44 U.S.C. 3501 et seq.
    2. Executive Order 12866 and Office of Management and Budget (OMB) 
    Review
        Under Executive Order 12866 (58 FR 51735; October 4, 1993), the 
    Agency must determine whether a regulatory action is ``significant'' 
    and therefore subject to OMB review and the requirements of the 
    Executive Order. The Order defines ``significant'' regulatory action as 
    one that is likely to lead to a rule that may either (1) have an annual 
    effect on this economy of $100 million or more, or adversely and 
    materially affecting 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, it has been decided 
    that this is a ``significant regulatory action'' within the meaning of 
    the Executive Order. For this reason, this action underwent OMB review. 
    The OMB reviewed and released the action without recommending any 
    changes.

      of these categories are subject to a negotiated standard for equipment
      leaks contained in the Hazardous Organic NESHAP (HON), which was      
      promulgated on April 22, 1994. The HON includes a negotiated standard 
      for equipment leaks from the SOCMI category and 20 non-SOCMI          
      categories (or subsets of these categories). The specific processes   
      affected within the categories are listed in Section XX.X0 (C) of the 
      March 6, 1991 Federal Register notice (56 FR 9315).
