[Federal Register Volume 83, Number 161 (Monday, August 20, 2018)] [Proposed Rules] [Pages 42066-42089] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-17933] ----------------------------------------------------------------------- ENVIRONMENTAL PROTECTION AGENCY 40 CFR Part 63 [EPA-HQ-OAR-2013-0290; FRL-9982-43-OAR] RIN 2060-AT25 National Emission Standards for Hazardous Air Pollutants for Clay Ceramics Manufacturing AGENCY: Environmental Protection Agency (EPA). ACTION: Proposed rule. ----------------------------------------------------------------------- SUMMARY: This action proposes amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Clay Ceramics Manufacturing. The proposed amendments are in response to a petition for reconsideration filed by industry stakeholders on the final rule promulgated on October 26, 2015, as well as our review of the 2015 rule with respect to other issues raised by stakeholders. This action proposes to revise the temperature monitoring methodology used to demonstrate continuous compliance with the dioxin/furan (D/F) emissions limit of the final rule. In addition, we are proposing to address concerns raised by industry stakeholders regarding visible emissions (VE) monitoring of tunnel kiln stacks for continuous compliance with particulate matter (PM) and mercury (Hg) emission limitations. This action also proposes to amend the requirements for weekly visual inspections of system ductwork and control device equipment for water curtain spray booths. Lastly, this action proposes to amend the NESHAP to include provisions for emissions averaging and make technical corrections. DATES: Comments. Comments must be received on or before October 4, 2018.

Table 1 of this preamble lists the NESHAP and associated regulated industrial source categories that are the subject of this proposal. Table 1 is not intended to be exhaustive, but rather provides a guide for readers regarding the entities that this proposed action is likely to affect. The proposed amendments, once promulgated, will be directly applicable to the affected sources. Federal, state, local, and tribal government entities would not be affected by this proposed action. As defined in the Initial List of Categories of Sources Under Section 112(c)(1) of the Clean Air Act Amendments of 1990 (see 57 FR 31576, July 16, 1992) and Documentation for Developing the Initial Source Category List (see EPA-450/3-91-030), the Clay Products Manufacturing source category, as originally listed, included any facility engaged in manufacturing of clay products such as brick, vitrified clay pipe, structural clay tile, and clay refractories. The Clay Products Manufacturing source category has since been replaced by the Brick and Structural Clay Products (BSCP) Manufacturing source category and the Clay Ceramics Manufacturing source category (see 67 FR 47894, July 22, 2002).

Following publication in the Federal Register, the EPA will post the Federal Register version of the proposal and key technical documents at this same website. A redline version of the regulatory language that incorporates the proposed changes in this action is available in the docket for this action (Docket ID No. EPA-HQ-OAR-2013-0290). II. Background A. What is the statutory authority for this action? The statutory authority for this action is provided by sections 112 and 307(d)(7)(B) of the Clean Air Act (CAA) as amended (42 U.S.C. 7412 and 7607(d)(7)(B)). B. What actions preceded these proposed amendments? The initial NESHAP for Clay Ceramics Manufacturing was published in the Federal Register on May 16, 2003 (68 FR 26690), and codified at 40 CFR part 63, subpart KKKKK, pursuant to section 112 of the CAA. These standards were challenged and subsequently vacated by the United States Court of Appeals for the District of Columbia Circuit in 2007. See Sierra Club v. EPA, 479 F.3d 875, 876 (D.C. Cir. 2007). Following the 2007 vacatur of the 2003 rule, the EPA collected additional data and information to support new standards for the clay ceramics industry. This information is contained in the docket at https://www.regulations.gov (see Docket ID No. EPA-HQ-OAR-2013-0290). On December 18, 2014, the EPA proposed new NESHAP for Clay Ceramics Manufacturing (79 FR 75622). The EPA received additional data and comments during the public comment period. These data and comments were considered and analyzed and, where appropriate, revisions to the NESHAP were made. The NESHAP for Clay Ceramics Manufacturing was finalized on October 26, 2015 (80 FR 65470). On December 23, 2015, Kohler Company (Kohler) petitioned the EPA for reconsideration of the final rule for Clay Ceramics Manufacturing (Docket Item No. EPA-HQ-OAR-2013-0290-0316). In this action, we are proposing revisions to the Clay Ceramics Manufacturing NESHAP based on information provided by Kohler in their petition, information collected by the EPA subsequent to the reconsideration request, and information collected by the EPA subsequent to our reconsideration request response. The intent of these proposed amendments is to provide some flexibility to the clay ceramics manufacturing industry, while maintaining the emissions and operational standards of the NESHAP. III. Summary of the Proposed Amendments The EPA is proposing the following amendments to 40 CFR part 63, subpart KKKKK, in response to Kohler's petition for reconsideration on the October 26, 2016, final rule (80 FR 65470): Revise the temperature monitoring methodology used to demonstrate continuous compliance with the D/F emissions limits from sanitaryware first-fire tunnel kilns. Provide an alternative to the monitoring provisions for VE from tunnel kiln exhaust stacks. Amend the requirements for weekly visual inspections of system ductwork and control device equipment for water curtain spray booths. Define cooling stacks in the rule and differentiate cooling stacks from kiln exhaust stacks for compliance purposes. Include provisions to allow emissions averaging for emissions from existing tunnel kilns and glaze spray booths and make associated revisions to the definition of affected source and recordkeeping and reporting requirements. The rationale for these proposed amendments is provided in section IV of this preamble. This action is limited to the specific issues raised in the petition for reconsideration, plus some minor technical corrections. There are no changes to emission limits in the [[Page 42069]] October 2015 final rule as a result of these proposed amendments. IV. Rationale for the Proposed Amendments A. Temperature Monitoring of Tunnel Kilns The December 18, 2014, action proposed to require continuous monitoring of kiln temperature as a performance parameter for demonstrating compliance with the D/F emission limitations. In their public comments, Kohler indicated that the proposed temperature limitation failed to account for the normal temperature variations that occur during operation of a kiln. The October 26, 2015, final rule changed the performance parameter from a minimum kiln temperature operating limit to a maximum stack temperature operating limit. In our response to Kohler's December 23, 2015, petition for reconsideration, we indicated that we would grant reconsideration of the temperature monitoring requirement (Docket Item No. EPA-HQ-OAR-2013-0290-0319). Subsequently, the EPA reviewed new data provided by Kohler regarding annual kiln operating temperatures (see Docket Item No. EPA- HQ-OAR-2013-0290-0340). The data indicate that there is variability in kiln operating temperatures based on kiln load and other factors. During production of sanitaryware products, the tunnel kiln operating temperature is used as the primary operating parameter to maximize quality assurance of the product (minimal defects), while minimizing fuel usage. In addition, there are periods, based on the number of products being run through the kiln (kiln load), and the variation of types of products included in each load, where the temperature set point must be adjusted to control the ``heat work'' through the kiln. Heat work is defined as the temperature and time factors that allow the sanitaryware body and glaze coatings to sinter, melt, flow, and fuse. The adsorption rate of the fired product (porosity) is determined by the heat work (see Docket Item No. EPA-HQ-OAR-2013-0290-0342). Based on this information gathered during our discussions with Kohler, we are proposing to amend the compliance demonstration requirements for sanitaryware first-fire tunnel kilns where no air pollution control devices are installed. In this scenario, we propose to require the affected sources to monitor kiln temperature during an initial D/F compliance test, consisting of three 4-hour test runs, for a total of 12 hours. From this 12-hour block of time, consisting of 1- hour increments, the affected sources would calculate two values: (1) The standard deviation of the 12 1-hour temperature measurements, and (2) 1 percent of the 12-hour block average. The affected sources would determine which of the two values would provide the greatest variability (i.e., the highest value) and would then add this value to the 12-hour block average measured during the compliance test. This value would become the maximum temperature at which the kiln would be allowed to operate during normal operations. We are setting a maximum operating limit because, due to variability, kiln operating temperatures at sanitaryware facilities sometimes fall below the value observed during the compliance test. Temperatures have also been found to fall in the duct. Under this scenario, the affected sources would be required to monitor 12-hour averages of their kiln during normal operations and demonstrate compliance by comparing these 12-hour averages to the value calculated during the D/F compliance test. This should allow variability of the hourly temperature fluctuations as a 12-hour block average and, additionally, provide variability by having multiple options for calculating the kiln variability into the operating limit. In this proposed amendment to the rule, owners or operators would be required to maintain records of performance tests and continuous compliance data as is required in the October 2015 final rule and would be required to comply with the corresponding reporting requirements of the October 2015 final rule. Accordingly, in this action, the EPA is proposing to amend Table 2 to 40 CFR part 63, subpart KKKKK, to include the revised operating limit, amend Table 4 to specify the requirements for establishing the operating limit during the D/F compliance test, and amend Tables 6 and 7 to specify the associated initial and continuous compliance requirements, respectively. These amendments to the rule only apply to sanitaryware first-fire tunnel kilns. The D/F compliance requirements of all other emission sources regulated by the rule remain unchanged. We are also requesting comment on whether to consider an alternative temperature monitoring requirement. Similar to the previous scenario, the affected sources would monitor kiln temperature during the initial D/F compliance test, calculate both the standard deviation of the 12 1-hour temperature measurements and 1 percent of the 12-hour block average, and decide which of the two values would provide the greatest variability (i.e., the highest value). However, this second scenario has the affected sources subtract this value from the 12-hour block average measured during the compliance test to determine the minimum temperature at which the kiln would be allowed to operate during normal operations. Similar to the previous scenario, this alternative would require the affected sources to monitor 12-hour averages of their kiln during normal operations and demonstrate compliance by comparing these 12-hour averages to the value calculated during the D/F compliance test. The proposed amendments do not change the requirement for affected facilities operating sanitaryware first-fire tunnel kilns to demonstrate compliance with the D/F emission limit through repeat 5- year stack testing. The proposed amendments to the rule provide affected facilities without air pollution control devices with a revised means to demonstrate continuous compliance at all times, including those times where facilities must adjust kiln temperatures to control the heat work through the kiln. If an affected facility determines through continuous kiln temperature monitoring that they cannot demonstrate compliance using the method proposed, they would be required to maintain kiln temperatures that demonstrate compliance until such time that additional stack testing could be performed and a new temperature threshold determined. B. Visible Emissions Monitoring of Tunnel Kiln Exhaust In its petition for reconsideration, Kohler explained the basis for its position that VE monitoring is not a useful parameter to assess kiln operations. In addition, Kohler explained that process errors that would potentially lead to an increase in VE from a kiln would more readily be identified through one of multiple parameters monitored continuously by the kiln operator. In our response to this request, we indicated that, although we were denying the reconsideration request on this issue, we would evaluate any additional information provided by Kohler and determine whether any further action would be warranted (see Docket Item No. EPA-HQ-OAR-2013-0290-0319). In a subsequent meeting, the EPA and Kohler discussed alternatives to the VE testing requirement in the final rule. The information provided by Kohler (see Docket Item No. EPA-HQ-OAR-2013-0290-0339) supports the [[Page 42070]] conclusion that monitoring kiln temperature is a more accurate and sensitive parameter in determining times when the PM emissions may be increased, rather than periodically monitoring VE from the kiln stack. As a result, the EPA is proposing to include an alternative that would require the source to first take the necessary steps to maintain the temperature profile of each tunnel kiln. For any incidence where a kiln exceeds its normal operating temperature profile, the source would then be required to perform VE observations at the stack of the affected kiln according to the procedures of EPA Method 22. Accordingly, in this action, the EPA is proposing to amend 40 CFR 63.8620(e) to include revised procedures for demonstrating continuous compliance to include the requirement for facilities to maintain normal kiln temperature, and only perform VE observations when the kiln temperatures are sporadic or out of the normal range of operation. Additionally, the EPA is proposing to amend Tables 2 and 7 to 40 CFR part 63, subpart KKKKK, to specify the operating limits and continuous compliance requirements, respectively. C. Weekly Visual Inspections of Water Curtain Spray Booths Regarding the issue of visual inspections for system ductwork and control device equipment for water curtain spray booths, Kohler and the EPA have discussed the weekly inspection requirement. Kohler representatives explained that current maintenance procedures eliminate the need for the weekly inspections. Kohler's operators routinely conduct preventative maintenance on the water curtain control, such as regular periodic fan maintenance, as well as a weekly wash-out. They also explained how their current procedures ensure that they become aware in a relatively short period of time if there is an issue with the water curtain or the ductwork, as they can see if particulates or other impurities are getting into the glaze that has been sprayed onto a piece of ware. If this were to occur, the operator would stop the glazing operations to fix the issue. Kohler provided the EPA additional information about the quarterly preventative maintenance that they conduct, available in Docket Item No. EPA-HQ-OAR-2013-0290-0331. Kohler also indicated that ductwork inspections do not have any value, since the water is the control, and, therefore, any air in the ductwork is already controlled (see Docket Item No. EPA-HQ-OAR-2013-0290-0336). During several visits to the Kohler facility in Spartanburg, South Carolina (see Docket Item Nos. EPA-HQ-OAR-2013-0290-0005, 0331, and 0341), the EPA observed the configuration of a typical spray booth, and the ductwork associated with the booth. From the observations, it was apparent that the booth operator would indeed be able to see if particulates or other impurities were getting into the glaze that has been sprayed onto a piece of ware, and that the requirement for weekly inspections would not be required based on the configuration of the booth. Based on its evaluation of the additional data, and after observing the water curtain spray booth operations at the Kohler facility in Spartanburg, South Carolina, the EPA is proposing to remove the weekly visual inspection requirement from the rule but retain the other two monitoring requirements (daily inspections to verify the presence of water flow to the wet control system and annual inspections of the interior of the control equipment). Accordingly, in this action, the EPA is proposing to amend Table 2 to 40 CFR part 63, subpart KKKKK, to remove the weekly visual inspections part of the operating limit for glaze spray operations equipped with a water curtain and amend Table 7 to remove the associated continuous compliance requirement. D. Cooling Stacks In its response to Kohler's petition that cooling stacks to be tested at sanitaryware manufacturing facilities should be limited to those with an oxygen content at or below 20.4 percent, the EPA noted that the value of 20.5 percent that the EPA finalized was based on the 20.5 percent threshold concentration provided by Kohler in an email to the EPA clarifying its testing proposal, and this email was present in the docket at proposal (see Docket Item No. EPA-HQ-OAR-2013-0290-0119). At the time, the EPA concluded that a reconsideration on this issue was not warranted pursuant to CAA section 307(d)(7)(B) and denied the reconsideration petition on this issue. Notwithstanding this denial, the EPA stated that it would evaluate any additional information provided by the petitioner and determine whether any further action is warranted (see Docket Item No. EPA-HQ-OAR-2013-0290-0319). In a subsequent meeting, Kohler and the EPA discussed Kohler's request to revise this aspect of the rule and options for any such revision, which included changing the oxygen content in the Clay Ceramics Manufacturing NESHAP from 20.5 percent to 20.4 percent or adding a definition for ``cooling stack'' that would exclude it from applicability (see Docket Item No. EPA-HQ-OAR-2013-0290-0331). As a result of this and later contacts (see Docket Item Nos. EPA-HQ-OAR- 2013-0290-0335 through 0338), the EPA has a better understanding of the purpose and operations of the cooling stacks. Based on this additional knowledge, the EPA is proposing to revise 40 CFR 63.8595(c) to specifically exclude cooling stacks from stack testing at sanitaryware manufacturing facilities, revise 40 CFR 63.8665 to include a definition for ``cooling stack'' and, for additional clarity, include a definition for ``products of combustion (POC) stack,'' which is the type of stack that would be tested. E. Emissions Averaging In its petition for reconsideration, Kohler requested that the EPA allow the use of emissions averaging as a compliance option in the Clay Ceramics Manufacturing NESHAP for existing tunnel kilns and glaze spray booths. Initially, in the December 18, 2014, proposed rule (79 FR 75649), the EPA had requested public comment on the use of emissions averaging in the BSCP Manufacturing NESHAP. In that 2014 proposal, we also noted that emissions averaging would not be applicable to new sources and could only be used between existing tunnel kilns in the same size subcategory (79 FR 75649). In this action, we are proposing amendments to 40 CFR 63.8595 in the Clay Ceramics Manufacturing NESHAP that would include alternative emissions averaging limits for the following: PM and Hg, in units of pounds per ton (lb/ton) of fired product for existing floor tile roller kilns; PM and Hg, in units of lb/ton of fired product for existing wall tile roller kilns; PM and Hg, in units of lb/ton of greenware fired for existing first-fired sanitaryware tunnel kilns; PM and Hg, in units of lb/ton of first-fired glaze sprayed (dry weight basis) for existing tile glaze lines with glaze spraying; and PM, in units of lb/ton of first-fire glaze sprayed (dry weight basis), for existing sanitaryware manual, spray machine, or robot glaze applications. As stated in the December 18, 2014, proposed rule, the EPA has concluded that it is permissible under the appropriate circumstances to establish within a NESHAP a unified compliance regimen that permits averaging within an affected source across individual affected units subject to the standard [[Page 42071]] under certain conditions (79 FR 75650). In addition, averaging across affected units is permitted only if it can be demonstrated that the total quantity of any hazardous air pollutant (HAP) will not be greater under the averaging mechanism than it could be if each individual affected unit complied separately with the applicable standard. The conditions required for emissions averaging include: (1) No averaging between different types of pollutants; (2) no averaging between sources that are not part of the same affected source; (3) no averaging between individual sources within a single major source if the individual sources are not subject to the same NESHAP; and (4) no averaging between existing sources and new sources. In this action, we are proposing that emissions averaging would be allowed if they meet the following requirements. First, emissions averaging would only be permitted between individual sources at a single existing affected source and would only be permitted between individual sources subject to the Clay Ceramics Manufacturing NESHAP. Further, emissions averaging would not be permitted between two or more different affected sources or between two or more sources in different subcategories. Finally, new sources could not use emissions averaging. In addition, we are proposing that any emissions averaging alternative would require each facility that intends to use emissions averaging to submit an emissions averaging plan, which will provide additional assurance that the necessary criteria will be followed. In such an emissions averaging plan, the facility would include the identification of: (1) All units in the averaging group, (2) the control technology installed, (3) the process parameter that will be monitored, (4) the specific control technology or pollution prevention measure to be used, (5) the test plan for the measurement of the HAP being averaged, and (6) the operating parameters to be monitored for each control device. Under the proposed emissions averaging provision, the emissions for each unit in the averaging group would be capped at the emission level being achieved on the effective date of the final rule. The caps ensure that emissions do not increase above the emission levels that sources currently are designed, operated, and maintained to achieve. In the absence of performance tests, in documenting these caps, the affected sources would document the type, design, and operating specification of control devices installed on the effective date of the final rule to ensure that existing controls are not removed or operated less efficiently. The proposed emissions averaging provision would not apply to individual units if the unit shares a common stack with units in other subcategories, because, in that circumstance, it is not possible to distinguish the emissions from each individual unit. For those cases where the emissions averaging provisions are used, the EPA is proposing to add a definition for ``emissions averaging sources'' in 40 CFR 63.8665 that includes those existing sources included in the emissions average. The EPA is also proposing to amend Table 1 to 40 CFR part 63, subpart KKKKK, to include the applicable emission limits determined under the emissions averaging provisions. In addition, the EPA is proposing to revise the reporting and recordkeeping provisions in 40 CFR 63.8630, 63.8635, and 63.8640 to include the following requirements where the emissions averaging provisions are used: (1) Certifying in the notification of compliance status that the emissions level achieved or the control technology employed is no less stringent than the level or control technology contained in the notification; (2) reporting in the compliance report the emissions level that was being achieved or the control technology employed on the effective date of the rule; and (3) keeping a copy of the emissions averaging implementation plan, all required calculations, including monthly records of process rate, as applicable, and monitoring records. The emissions averaging provisions that we are proposing are based in part on the emissions averaging provisions in the Hazardous Organic NESHAP (HON). The legal basis and rationale for the HON emissions averaging provisions were provided in the preamble to the final HON (59 FR 19425, April 22, 1994). F. Technical Corrections Technical corrections are being proposed to correct inaccuracies that were promulgated in the final rule, replace text that might be considered confusing, and correct outdated information. We are soliciting comment only on whether the proposed changes provide the intended accuracy, clarity, and consistency.

Summary of Cost, Environmental, and Economic Impacts This action will have no cost, environmental, energy, or economic impacts beyond those impacts presented in the October 26, 2015, final rule for Clay Ceramics Manufacturing and may result in a cost savings due to the changes in monitoring and testing requirements discussed in the previous section. The technical corrections are cost neutral. VI. Statutory and Executive Order Reviews Additional information about these statutes and Executive Orders can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders. A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review This action is not a significant regulatory action and was, therefore, not submitted to the Office of Management and Budget (OMB) for review. B. Executive Order 13771: Reducing Regulations and Controlling Regulatory Costs This action is considered an Executive Order 13771 deregulatory action. The proposed rule is expected to provide meaningful burden reduction by deregulating aspects of the sanitaryware manufacturing process, but do not result in changes in costs to comply. C. Paperwork Reduction Act (PRA) This action does not impose any new information collection burden under the PRA. Burden is defined at 5 CFR 1320.3(b). OMB has previously approved the information collection activities contained in the existing regulation (40 CFR part 63, subpart KKKKK) and has assigned OMB control number 2060-0513. This action does not change the information collection requirements. D. Regulatory Flexibility Act (RFA) I certify that this action will not have a significant economic impact on a substantial number of small entities under the RFA. In making this determination, the impact of concern is any significant adverse economic impact on small entities. An agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, has no net burden, or otherwise has a positive economic effect on the small entities subject to the rule. This proposed rule will not impose any additional requirements on small entities, only alternatives to existing requirements. We have, therefore, concluded that this action will have no net regulatory burden for all directly regulated small entities. E. Unfunded Mandates Reform Act (UMRA) This action does not contain an unfunded mandate as described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect small governments. The action imposes no enforceable duty on any state, local, or tribal governments or the private sector. F. Executive Order 13132: Federalism This action does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government. G. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments This action does not have tribal implications as specified in Executive Order 13175. It will neither impose substantial direct compliance costs on federally recognized tribal governments, nor preempt tribal law. The proposed amendments impose no requirements on tribal governments. Thus, Executive Order 13175 does not apply to this action. H. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks The EPA interprets Executive Order 13045 as applying only to those regulatory actions that concern environmental health or safety risks that the EPA has reason to believe may disproportionately affect children, per the definition of ``covered regulatory action'' in section 2-202 of the Executive Order. This action is not subject to Executive Order 13045 because it does not concern an environmental health risk or safety risk. I. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use This action is not subject to Executive Order 13211, because it is not a significant regulatory action under Executive Order 12866. J. National Technology Transfer and Advancement Act (NTTAA) This rulemaking does not involve technical standards. K. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations The EPA believes that this action does not have disproportionately high and adverse human health or environmental effects on minority populations, low-income populations, and/or indigenous peoples, as specified in Executive Order 12898 (59 FR 7629, February 16, 1994). The documentation for this decision is contained in the docket (See ``EJ Screening Report for Clay Ceramics,'' Docket Item No. EPA-HQ-OAR-2013- 0290-0241).
