Summary: This notice announces the availability of a preliminary draft of the list of categories and subcategories required under Section 112(c) of the Clean Air Act (CAA) as amended in 1990. The CAA requires that Ha list of all categories and subcategories'' (hereafter collectively referred to as categories) "of major sources and area sources.......... (listed under section 112(c)(3)) of hazardous air pollutants (HAFs) be published within 1 year of enactment of the CAA Amendments of 1990. This notice provides the public with an opportunity to comment on the preliminary draft list of categories prior to the publication of the final list (scheduled to be published in November of 1991). Facilities within these categories of sources are potentially subject to emissions standards under section 112 of the CAA, The schedule for promulgation of these standards will be published within 2 years of enactment of the CAA Amendments of 1990. The identification of categories and subcategories of major source* in this preliminary draft listing has no bearing on whether any particular facility or grouping is a "source" for purpose of the early reduction* program under Section 112(i)(5), or a "major eource" for purposes of Section 112(a)(1). The term "major source" is defined under Section 112(a)(1) in such a way that it refer* to the emissions occurring from a contiguous ares under common control,. By contrast. EPA must identify "categories and subcategories" of major and area source generic*lly for the purposes of today's preliminary draft list and standard setting under Section 112(d). In most case*, this identification will be made as product or process oriented groupings which will not affect the definition of "eource" for purpose* of either the early reductions under section 112(i)(5) or the definition of a "major source" under eection 112(a)(1). The definition of source in the early reduction program is described in Section DJi. of the Proposed Regulations Governing Compliance Extensions for Early Reduction of Hazardous Air Pollutants (June 13,1991.56 FR 27338). Today's drift list is not the final list that EPA will use as the basis for publishing the scheduling for promulgation of emission standards In November 1992. Hie publication of a list of categories of major sources and area sources enables potentially affected sources, the public, and regulatory agencies to understand the acope of the HAP control program. Through this notice, the Agency solicits comment on the preliminary draft list of categories of major and area sources subject to standards. The Agency also solicits comment on the procedures used to develop this list, and alternative Interpretations of the subject legislation. DATES: Comments. Written comments must be received on or before July 21, 1991. Requests for extensions to this comment period are not anticipated to be granted, due to the limited time available for list publication.

SUFFLEMEMTARY INFORMATION: L Background The CAA Amendments of 1990 [Pub. L101-849] require, under the revisions to section 112, that EPA evaluate and control emissions of HAFs. The control of HAFs is achieved through promulgation of emission standards under sections 112(d) and 112(f) for categories of sources that emit HAFs. This notice outlines the procedure* used to identify a list of categories of major sources end ares sources of HAFs. and includes a preliminary draft list of such categories. The term "major source" at defined in paragraph 112(e)(1) to mean "any stationary source or group of stationary sources located within a contiguous area and under common Si. o62471 Federal Register / Vol. 56, No. 120 / Friday. June 21, 1991 / Notices 28549 control that emits or has the potential to emit considering controls, in the aggregate, 10 tons per year or more of any hazardous air pollutant or 25 tons per year or more of any combination of hazardous air pollutants." The EPA may establish a lesser quantity of pollutant emissions for a major source than that specified in the previous sentence, based on various characteristics of the pollutant including potency, persistence, potential for bioaccumulation, or other relevant factors. The EPA may establish different criteria for a major source in the case of radionuclides. The term " area source," as defined in section 112(a)(2). means any stationary source of HAP"s that is not a major source. Section 112(c) requires EPA to list "categories of major sources and area sources." Because most groupings of sources are based on process or product-oriented criteria, they may include a mix of both major and area sources. The distinction between categories of major and area sources is discussed in more detail below. Section 112(b) of Title HI includes a list of chemicals, compounds, or groups of chemicals. Section 112(c)(1) requires EPA to publish, within l year of enactment of the CAA amendments of 199(1 a list that includes all categories of major sources of these RAP's. Section 112(c)(3) requires EPA to include on this list each category of area sources that EPA finds presents a threat of adverse effects to human health or the environment (by such sources individually or in the aggregate) warranting regulation under section 112. There are additional specific requirements for listing categories under section 112(c)(3) and section 112(c)(6). Section 112(c)(3) refers to the tree source* strategy under section H2(k). This strategy requires, within 5 years of enactment of the CAA amendments, listing of categories of area sourcea which address 90 percent of the aggregate emissions of 30 HAP*. Section 112(c)(6) requires the listing of categories of sources which address 90 percent of the aggregate emissions of seven specific pollutants within S years of enactment of the CAA amendments, Although some of the categories that will be identified under these section* ere probably already Included on today's preliminary draft list there are likely to be others which have not yet been identified due to a lack of data. The publication of today's draft list does not constitute completion of the requirements under section 112(c)(3) or section 112(c)(6). Specific requirements are also provided for hating research facilitiee (section 112(c)(7)). boat manufacturing (section 112(c)(8)). and oil and gas wells and pipeline facilities (section 112(a)(4)). Tbe EPA must periodically, but no leBs often than every 6 years, in response to public comment or new information, revise, if appropriate, the list of categories. The EPA may at any time designate additional categories of HAP sources according to tbe same criteria as were appUed to tbe initial list. Under section 112(c)(9), tbe EPA may delete a category from the list, bused on petition of any person or on tbe Administrator's own motion, whenever certain determinations are made. In the case of HAP's emitted by sources in listed categories that may result in cancer in humans, the EPA may delete a category if it is determined that no source in the category (or group of sources in the case of area sources) emits such HAP's in quantities which may cause a lifetime risk of cancer greater than 1 in 1 million to the individual in the population who is most exposed to such emissions. In the case of HAP's emitted by sources in the category that may result in adverse health effects in humans other than cancer or adverse environmental effects, the EPA may delete a category if no source in the category (or group of sources in the case of area sources) emits such HAP's in quantities that exceed a level which is adequate to protect public health with an ample margin of safety and no advene environmental effect will result from emissions from any source (or group of sources in the case of area sources). The EPA shall grant or deny a petition to delete a category within 1 year after the petition ia filed. Procedures for such petitions will be addressed in a separate Federal Register notice. Section 112(c)(2) requires establishment of emission standards under section 112(d) for every category of sources included on the final list to be published under section 112(c)(1). The emission standards written for the categories listed under section 112(c) shall be promulgated according to tbe schedule for standards set forth in section 112(e). Section 112(e) requires EPA to determine the priorities for promulgating emission standards for listed categories under section 112(d). In determining such priorities. EPA shall consider the known or anticipated adverse effects of the emitted pollutants on health and the environment tbe quantity and location of emissions; and the efficiency of grouping categories according to the pollutants emitted, or the processes or technologies used. A schedule establishing a date for promulgation of emission standards for each category of HAP sources is to be published in a separate Federal Register notice, after an opportunity for comment, within 24 months of enactment (i.e.. by November 15,1992). A. Discussion of Major Issues 1. Categories and Subcategories; Section 112(d)(1) states that in establishing emission standards that EPA "may distinguish among classes, types and sizes of sources within a category or subcategoryThe terms "category" and "subcategory" are not defined under section 112 The EPA has not distinguished categories from subcategories in today's preliminary draft Ust Table 1, which is the preliminary draft list of categories, is arranged in large groups of industries. For some of these industry groupings, EPA has more data available to facilitate the identification of categories. For example, the air toxica emissions from the industry group identified as "Production of Synthetic Organic Chemicals" have been studied extensively and, therefore, many categories within this group have been identified In this case, it may be useful to define the industry group as s category and to define all of the categories within this group as subcategories. For other industry groups, however, not as much is known about the processes involved and the resultant air toxics emissions. It is likely that further subdivision of msny of the groups for which there is less information will be recognized as more data becomes available. The issue of defining categories and subcategories is important in the development of the schedule of standards required under section 112(e). Section 112(e)(1) outlines a schedule for the promulgation of emission standards ir .--oops that are to be promulgated w - 2 4.7. and 10 years after ei nent of the CAA amendments. TL chedule is to be based on the "categories of sources initially listed for regulation pursuant to subsection (c)(1)." Today's notice announces the preliminary draft of the list of categories. The definitive list which will form the basis for the schedule for standards, U scheduled to be published In November of 1991 after opportunity for comment for today's preliminary draft list Once the definitive list la published, however, Section 112(e)(1) requires that the categories of sources "initially" listed are to be used to develop the schedule for promulgation of emission standards. This means that if the categories on this Ust are 062^*72 SU 28550 Federal Register / Vol. 56, No. 120 / Friday, June 21. 1991 / Notices subsequently divided into subcategories, all of these subcategories would have to be regulated on the same achedule (La., within either 2,4,7 or 10 yean after enactment of the CAA amendment*). If EPA intends to regulate various subcategories of a category at different times (e.g., regulate one subcategory within 4 year* but other subcategories in the same category within 7 years), the subcategories need to be identified separately on the list of categories and subcategories to be published in November, 1991. * Due to a lack of information regarding characterization of industries, today's preliminary draft list may include categories whidi encompass multiple subcategories. The EPA is soliciting comment on the criteria for defining categories and subcategories. In addition, EPA is requesting information which could be used for the definition of eubcategories for the groups of sources on today's preliminary draft list 2. Listing of Categories of Area Sources: As noted above, section 112(c)(3) requires that EPA list categories of area sources that present "a threat of adverse effects to human health or the environment" warranting regulation under section 112. Categories of area sources may also be added to the Ust in satisfaction of the requirements of section 112(k)(3)(B) (area source strategy) or section 112(c)(6) (sources of specific pollutants). The showing required for listing categories of area sources under section 112(c)(3) would not apply to the additional requirements under these provisions. The draft list of source categories which accompanies today's notice does not distinguish between categories or major and area sources and does not present specific findings in support of the presence of categories of area sources on the list. As described in the following section, the information used to develop this list is not sufficient to adequately determine whether individual facilities within listed categories exceed the major source definition (La., emission of 10 tons per year for one listed pollutant or 25 tons per year for a combination of listed pollutants or a lesser quantity for highly toxic pollutants). Although additional data are being gathered as well as solicited through this notice, the EPA anticipates that major information gaps will continue to exist by the November 1 Nothing in this notice or lift ahell limit EPA'i authority to promulgate amiaiion etendanb (or an entire facility or portion thereof, regudleof of the number of tource categonea and aubcatagoriaa contained to tna' facility. 15,1991 statutory deadline for publication of the list of source categories. Several approaches are under consideration for addressing area source categories in the November listing. These include: a. Constrain the initial list to categories of major sources and those categories of area sources that are sufficiently well characterized to permit findings of potential adverse effect* threat Additional categories of area sources would be subsequently added to the list on the basis of further study and a finding of potential adverse effects. Such a finding could be made at any time prior to or at the proposal of a relevant emission standard. An example of a well characterized category whidi is composed of a majority of area sources is commercial ethylene oxide sterilization. Although there are some major sources within this category, the majority of the sources are, under the definition in the CAA amendments, area sources. The EPA has evaluated this category for regulation development for several years and has collected substantial information on the emissions, potential health impacts end control techniques available for commercial ethylene oxide sterilizer*.-. Under this approach, the data available for commercial ethylene oxide sterilization would likely be sufficient to make the determination to indude this category on the list however, the nature of the specific finding necessary for listing would need to be defined (i.aM the data necessary to indicate the threat of adverse health effect*). Although the ethylene oxide sterilization category provides an example of a well characterized category composed of mainly area sources, the amount of detailed information which exlti for this category is not intended to represent the minimum necessary to make an advene effects finding to support the listing of categories of area sources. b. Make an interim finding that all categories of area sources era candidates for listing by virtue of their emissions of listed hazardous air pollutants. Remove any categories determined to be inappropriately listed through the source category deletion provisions in section 112(c)(9) as outlined previously. Under this approach, all categories included in the November listing, whether composed of major or area sources, would be subject to emissions standards under section 112 unless deleted from the list prior to proposal of a relevant standard. The risk-based findings for deletion from the list (he., all facilities in the category pose lifetime cancer risk of less than l in 1 million for the most exposed individual and have a level of emissions which protects against other health and environmental effects with an ample margin of safety) would be operative for such deletion* c. Develop a method for making the required finding for listing categories of area sources that is commensurate with the limitations of available data and apply the method comprehensively in the November publication. Approaches could include: evaluating the magnitude and nature of available data on constituent emissions, constructing a hazard or relative toxicity ranking of the pollutants emitted, or some combination of the above. This approach would involve the development and application of criteria to support a finding of potential adverse effects required for the listing of categories of area sources. While a similar finding would also be needed for Approach a, under this approach the finding would be applied to all identified categories of area sources prior to the November publication of the list Such a finding would be based on the limited data available supplemented by public comments prior to November. For example, if the finding were baaed, in part on the magnitude of emissions of listed pollutants, the EPA would attempt to estimate the emissions for all identified categories of area sources in advance of the November publication of the list In comparison to Approach a, the finding required for listing categories of area sources under this approach would likely be less rigorous given the time constraint of the November ublication deadline. This approach, owever, would result in a more comprehensive initial list than toe approach envisioned under Approach a. The EPA requests comment on these or alternative approaches to toe incorporation of area aources in toe category list The EPA also requests comments on alternative methods for making the "threat of adverse effects" finding for listing categories of area sources under section 112(c)(3). 3. Utility and Solid Waste Incineration Categories: The listing of some categories of HAP-emitting sources is affected by other sections of the CAA. The regulation of electric utility steam generating units (above 25 megawatts electrical output hereafter referred to as categories of utilities) under section 112 is dependent on the outcome of a study of this industry mandated under section 112(n)(l). The Agency is contemplating two alternatives for the listing of categories of utilities. The first alternative is to omit categories of SL 062473 Federal Register / Vol. 58, No. 120 / Friday, June 21, 1991 / Notices 28551 utilities from the list until such time as the conclusions of the section 112[n)(l) study indicate that these categories warrant regulation under section 112. This alternative, however, may appear inequitable because it would preserve the listing and regulation of other (potentially smaller) categories of non utility boilers (e.g., industrial boilers) while omitting, at least until the completion of the section 112(n)(l) study, utility boilers. The second alternative is to include categories of utilities on the list until such time as the conclusions of the section 112(n)(l) study indicate that these categories do not warrant regulation under section 112. While this alternative would appear to be more equitable, it would require an action to delete the utility categories from the list if the section 112(n)(l) study concludes that these categories do not warrant regulation under section 112. Such a deletion action would be subject to the risk-based findings required under section 112(c)(9) (outlined above). Categories of utility boilers above 25 megawatts of electrical output have been omitted from today's preliminary draft list The Agency is soliciting comment on the appropriate alternative to employ for the listing of categories of utilities. An additional group of categories on the list which are affected by another CAA section are the solid waste incineration categories. Municipal waste combustors, medical waste incinerators as well as commercial and industrial waste incinerators are specifically addressed under the authority of section 129. The categories included on the list developed under section 112(c) are sub)ect to regulation under section 112. Solid waste incineration categories subject to regulation under section 129 should not be listed under section 112(c). Municipal waste combustors, medical waste incinerators and general industrial solid waste incineration were omitted from today's preliminary draft list because these categories are specifically addressed under section 129. Due to a lack of data, however, there may be other categories on today's preliminary draft list which could be defined as categories of commercial or industrial solid waste incineration. The Agency is soliciting information on listed categories which are engaged in commercial or industrial incineration of solid waste as defined under section 129. B. Identification of Categories The preliminary draft list of categories is presented in Table 1. The section below describes the approach used for the development of today's preliminary draft list as well as the rationale for the use of this approach. The general approach employed to identify categories of major and area sources was to identify all such categories associated with the emission of one or more of the listed HAP's. The basis for this approach originated from a review of the available data sources for this activity. There is no single comprehensive and complete source of information regarding the emissions of HAP's from industries in the United States. In addition, most of the data sources provide information covering only a limited range of industrial sectors (e.g., manufacturing). Some of these data sources are not specific to the listed air toxics or do not give source specific information regarding emission of HAP's. Given the relative paucity of available data and the need to be comprehensive in identification of categories of HAP-emitting sources, the approach employed herein was to Identify and include in the preliminary draft list any category associated with the emission of one or more HAP's. The information sources available for this activity do not in many cases, support a further breakdown of this list and. thus, ' today's notice does not distinguish between categories of major and area sources. In addition, for many of the industries identified, there were insufficient data to distinguish source categories from subcategories. It is envisioned that such refinements will be made as the EPA learns more about the listed categories either in the regulatory development process or through information submitted from the public. Several sources of information were used to identify categories of sources emitting HAP's. A document entitled "Documentation for Developing the Source Category List" which catalogs the literature source(s) used to identify specific categories is included in the docket The date sources used are described below: 1. The National Emissions Data System (NEDS) is an EPA data base of reported emissions from sources emitting more than 100 tons per year of criteria pollutants (U.S. E'A, 1988), including volatile organic compounds (VOC) and particulate matter (PM). (NOTE: In 1990, the NEDS system was replaced with a new EPA software system, the Facility Subsystem of the Aerometric Information Retrieval System (AFS). The 1985 NEDS data have been converted to AFS.) The sources included in NEDS are classified by unique identifiers, termed source classification codes. Speciation profiles have been assigned to each of the source classification codes. These speciation profiles are an estimate of the chemical species breakdown of the total VOC or PM constituents for a category. Species profiles from EPA's Air Emissions Species Manual were applied to the VOC and PM emission estimates in NEDS in order to identify if HAP emissions are associated with a particular source category. Species profiles offer a means of estimating the weight percent of specific pollutants in an emission stream based on knowledge of the type of source category and quantity of VOC or PM emissions. Species profiles have been developed by EPA for a number of purposes including the preparation of air toxics and acid precipitation emission inventories, receptor modeling and ozone strategy development EPA has published species factors with assigned data quality rankings ranging from A to E. An "A" quality ranking indicates the highest quality profile, based on a composite of several tests and accepted analytical techniques, and can be considered representative of the total population of sources within a category. Conversely, an "E" quality ranking indicates the lowest quality profile, based on engineering calculations from only one source or perhaps simply based on engineering judgement and may not be considered representative of the total population of sources within a category. EPA. in preparing today's draft source category list using the NEDS data, only employed species profiles having data quality rankings of A, B, C and D. The use of profiles with a ranking of E was not considered appropriate because of the extreme uncertainty of the applicability of these profiles, even to a single source within a source category. , Profiles with a quality ranking of D are based on measured emissions from a single source or engineering calculations from more than one source. The use of profiles ranked D and higher was considered appropriate because EPA believes a profile need only be representative of one or several sources within a category in order to qualify that source category for inclusion on today's draft list EPA requests comment on this approach. There are several limitations to the use of the NEDS estimates and speciation factors to identify categories of emission sources. First, States are only required to report data for sources emitting more than 100 tons per year of a criteria pollutant Second, not all categories have been identified within the NEDS, especially many of the categories that produce or use organic chemicals. The NEDS emission profiles SL 062474 28532 Federal Register / Vol. 56, No. 120 / Friday, June 21, 1991 / Notice* generally were developed to aid the methods described above had modeling of criteria pollutants, not at a already identified most of the batii foT a toxic pollutant inventory. categories.
