1.0	INTRODUCTION 

      This memorandum presents the hazardous air pollutant (HAP) emissions and related information for the 14 coke oven facilities in the United States (U.S.) as part of the residual risk modeling for the Residual Risk and Technology Review (RTR) of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coke Ovens: Pushing, Quenching, and Battery Stacks (PQBS) (40 CFR, part 63, subpart CCCCC), as required under section 112 of the Clean Air Act (CAA), section 112(f)(2) and (d)(6); and the technology review of the NESHAP for Coke Oven Batteries (40 CFR, part 63, subpart L), as required under CAA section 112(d)(6). In accordance with section 112(d)(2) and (3) of the Clean Air Act (CAA), the U.S. Environmental Protection Agency (EPA) promulgated a NESHAP for coke oven facility sources under the PQBS NESHAP on April 14, 2003 (68 FR 18008). The 2003 Coke PQBS NESHAP established maximum achievable control technology (MACT) standards for pushing, quenching, and battery stacks. Under section 112(f)(2) of the CAA, the EPA is required to perform a residual risk analysis of MACT standards within eight years of promulgation, unless otherwise required by the CAA.[1] In addition, the EPA is required to perform a technology review of MACT standards every eight years under section 112(d)(6) of the CAA. The Coke PQBS NESHAP RTR was due in 2011. The MACT for the Coke Oven Batteries NESHAP was promulgated on October 27, 1993 (58 FR 57898) and set standards for leaks from oven doors, lids, and offtake, and for charging. The RTR for Coke Ovens Batteries (MACT-track facilities) was promulgated on April 15, 2005 (72 FR 19992). The technology review of the facilities under the Coke Oven Batteries NESHAP was due in 2013. The risk review for the Coke Ovens Batteries LAER track facilities (9 of the 14 coke facilities) was due in 2020. 
      
The purpose of this memorandum is to provide the emissions and operating information for coke oven facilities as part of the RTR. Details of the data and emission estimating procedures are provided in the memorandum titled "Coke Ovens Risk and Technology Review: Data Summary" (hereafter called the Data Memorandum), located in the dockets for these rules (Docket ID No.'s EPA-HQ-OAR-2002-0085 (Coke PQBS NESHAP); and Docket ID No.'s EPA-HQ-OAR-2003-0051 (Coke Oven Batteries NESHAP)). Section 2 provides background for the current regulatory effort. Section 3 contains the estimated HAP emissions in terms of tons per year (tpy) and pounds per ton (lb/ton). Section 4 contains the estimated EPA Method 303 coke oven emissions (COE) from battery leaks. Section 5 contains a summary of opacity data. Section 6 lists the references used. Abbreviations can be found in Appendix A. Additional industry information can be found in Appendices B through D.

2.0	BACKGROUND

2.1	Coke Production Process
In the coke production process, coal is heated in ovens in the absence of air to temperatures approaching 2,000°F (1,100[o]C), which drives off most of the volatile organic constituents of the coal, as gases and vapor, to form coke, which consists almost entirely of carbon. Coal is charged into the top or end of the oven, depending on the process, and the finished coke is pushed out using doors on both ends of the ovens. The hot coke product is cooled in quench towers that use water spray to cool hot coke in rail cars that drive into the bottoms of quench towers. The coke product is used either in blast furnaces in the integrated iron and steel industry (II&S) or at iron and steel foundries that produce iron molds for shaping molten metal. Coke oven temperatures are slightly higher to produce blast furnace coke than foundry coke. Coking lasts for 15 to 18 hours to produce blast furnace coke and 25 to 30 hours to produce foundry coke. 
The coke ovens are arranged in a series of adjacent ovens called batteries, where one battery may have up to 100 ovens and multiple batteries may be used by one facility. For the 14 coke facilities in the Coke Oven Risk Modeling Database, the number of batteries per facility ranged from 1 to 10, and the total number of ovens at the facility ranged from 56 to 708, with median values of 3 batteries per facility and 126 ovens total at the facility. Ovens at byproduct (ByP) coke facilities are tall and narrow (approximately 20 ft/6 m by 1.3 ft/0.4 m); whereas, at heat and nonrecovery recovery (HNR) facilities, the ovens are short and wide (approximately 7.8 ft/2.4 m by 12 ft/3.6 m). Byproduct coke ovens are operated at positive pressure, whereas HNR ovens operate under negative pressure. The organic gases and vapors that evolve from the ovens are removed through an exhaust system: for ByP plants, gases are sent to a chemical recovery plant (regulated under the 40 CFR part 61, subpart L NESHAP) that recovers chemicals and other products for sale and also cleans the coke oven gas. For nonrecovery (NR) plants (i.e., no chemical recovery) with heat recovery, the oven gases are sent to a heat recovery steam generator (HRSG) that produces power for sale and also to units that perform gas cleaning for sulfur and PM; for NR plants without heat recovery, oven exhaust gases are released to the surrounding air through waste heat stacks. 
2.2	Data Obtained for the Coke Ovens RTR
The primary source of data for the Coke RTR was the responses to two CAA section CAA 114 information requests (CAA 114 request) sent to selected facilities in the coke industry in April 2016 and June 2022 that included a questionnaire and a source test request (EPA, 2023). The EPA sent the CAA 114 requests under the authority of section CAA 114 of the CAA (42 U.S.C. 7414) to acquire the necessary data for the RTR for Coke PQBS NESHAP and the technology review for Coke Oven Batteries NESHAP. The questionnaire portion of the coke ovens CAA 114 requests included questions pertaining to inventory, process, and control devices for the emission units at the coke facilities. The source test request portion of the CAA 114 requests described the source tests, the test methods to be used, the pollutants to test, and other details concerning the requested testing. Copies of the CAA 114 requests and responses received by the EPA are included in dockets for both coke ovens rules (Docket ID No.'s EPA-HQ-OAR-2002-0085 (Coke PQBS NESHAP); and Docket ID No.'s EPA-HQ-OAR-2003-0051 (Coke Oven Batteries)).
The questionnaire portion of the 2016 CAA 114 request was sent to nine Coke companies that included 11 coke facilities operating in 2016: Mountain State Carbon, LLC (later purchased by AK Steel); AK Steel Corporation (that owned two coke facilities in 2016 and owned three coke facilities by 2019); ArcelorMittal Burns Harbor LLC; ArcelorMittal Monessen LLC; ArcelorMittal Warren LLC; Erie Coke Corporation; DTE Energy Services, Inc.; Sun Coke Energy, Inc. (which owns five coke facilities, of which three responded to the ICR) and U.S. Steel. The test request portion of the 2016 CAA 114 request was sent to seven of the 11 coke facilities operating at that time. Four coke facilities that did not receive the ICR that were operating in 2016 were: ABC Coke; Bluestone Coke; and two Sun Coke facilities, Indiana Harbor Coke and Jewell Coke and Coal. The questionnaire portion of the 2022 CAA 114 request was sent to six companies that included eight facilities operating in 2022 at six coke companies: ABC Coke; Cleveland-Cliffs (3 facilities); DTE Energy Services; Sun Coke Energy (2 facilities), U.S. Steel, and Cokenergy. The test request portion of the 2022 CAA 114 request also was sent to eight facilities. For details of the data obtained for the Coke RTR, see the Data Memorandum.
Table 1 lists the coke facilities and companies that were operating in 2016 and which facilities received the 2016 and 2022 CAA 114 requests; the type of coke produced; whether the facilities submitted data and/or performed source testing; and the estimated annual coke production per facility. In 2020, Cleveland-Cliffs, Inc., acquired AK Steel's cokemaking facilities in Follansbee, WV (Mountain State Carbon) and Middletown, OH, and ArcelorMittal USA LLC cokemaking facilities in Burns Harbor, IN; Monessen, PA; and Warren, OH. Appendix A lists the short names used for the coke facilities along with their full names and current ownership (Table A-1). Appendix A also includes other abbreviations used in this memorandum (Table A-2) and the individual HAP included in the HAP chemical groups (Table A-3).
3.0	FACILITY EMISSIONS AND OPERATION
Information submitted for the CAA 114 request was used to estimate emissions from coke facilities from the emission units and processes. Details of the procedures used to develop the emission estimates from the CAA 114 request data are describe in the Data Memorandum.[2] The coke facility emissions obtained from the test reports were analyzed and then reported in a few formats for use in regulatory development, as follows: 
Table 2 summarizes the HAP emissions (in tpy) used in risk modeling for the PQBS NESHAP (and refered to here as "source category emissions") and also for "noncategory" emissions in the risk analysis, which included the Coke Oven Batteries NESHAP sources, as well as other noncategory sources, with overal total HAP emissions by facility.
Table 3 presents the same data as Table 2 in units of lb/ton, using the average production shown in Table 1.
Table 4 shows the total HAP emissions in tpy used in the risk modeling for the PQBS NESHAP, by process, facility, and source category (PQBS NESHAP and noncategory), with door leak emissions under the Coke Oven Batteries NESHAP calculated using the alternative equation. See Appendix C for the same table using the original door leak emission equation. 
    Table 5 presents the metal HAP emissions for PQBS NESHAP sources used in risk modeling for coke oven facilities, by facility and process in tpy.
    Table 6 shows the noncategory ByP chemical plants HAP emissions by facility and HAP, with default industry averages used to estimate emissions for facilities without industry data.
Table 7 shows the noncategory HAP emissions by facility including: Coke Oven Batteries NESHAP sources (charging, doors, lids, offtakes), ByP chemical plant, boiler stacks, flares, other miscellaneous sources, and co-located II&S emissions.
    Tables 8 through 21 show the individual facility HAP emissions used in risk modeling by PQBS NESHAP process (in tpy) for each of the 14 coke ovens facilities. 
    Table 22 shows the HAP emissions by facility from HNR HRSG bypass and waste heat stacks for all HNR facilities. 
   
      Although the focus of the current rulemaling effort was on HAP emissions, particulate matter (PM) emissions were also determined in the course of collecting HAP emission data and in some cases used to apply HAP test data to facilities that did not test. The PM emissions for PQBS NESHAP sources are shown in Table 23, by process and facility, in tpy. 
      
      The 2016 test portion of the CAA 114 request was performed by 7 coke facilities: 5 ByP facilities and 2 HNR facilities. The 2022 test portion of the CAA 114 request was performed by 8 coke facilities: 6 ByP and 2 HNR facilities. These facilities and the processes that were tested are shown in Table 24, by process. The coke processes are controlled by various control technologies. Table 25 shows the pollutant control methods used in coke processes by coke oven facilities for both PM and volatile organic compound (VOC) control as well as the work practice controls. Table 26 summarizes the EPA Method 303 Charging, Door, Lids, and Offtakes data and the Coke Oven Batteries NESHAP limits. Table 27 summarizes the allowable-to-actual ratios for ByP door leaks using the alternative door leak equation to calculate emissions. Table 28 summarizes the average opacity observations for pushing, battery combustion, boiler, HRSG Main, HRSG bypass/waste heat, and HNR charging stacks and quench towers.

2 T = Facility also performed testing as part of CAA 114 request.
[3] Typical production as estimated by one or more of the following: (1) facilities in their CAA 114 request responses: (2) industry during the CAA 114 request review process; (3) 1998 coke production values from the NESHAP for Coke Ovens: Pushing, Quenching, and Battery Stacks  -  Background Information for Proposed Standards (EPA, 2001a); or (4) 55 percent capacity utilization of coke production design capacity from CAA 114 request responses for facilities that did not provide actual coke production values. See the Data Summary[2] for more details.
[4] The Erie Coke facility closed in 2019; however, the data were used in the Coke Emissions Database to estimate emission for other coke foundry facilities. 
[5] Cokenergy operates a combined heat and power system that uses the waste heat in the flue gas from Indiana Harbor Coke Company's (IHCC) metallurgical coke facility to produce steam and electricity for the Cleveland-Cliffs Indiana Harbor integrated steel mill. Cokenergy owns and operates the 16 HRSG to recover heat from the flue gas to allow for environmental treatment by the flue gas desulfurization system.

[5] Includes noncategory emissions from Coke Oven Batteries NESHAP sources (charging, Doors (using alternate equation), lids, offtakes) boilers, flares, 40 CFR part 61, subpart L NESHAP ByP chemical plant, co-located II&S facilities, and other operations. 
[6] Co-located II&S (noncategory) emissions: CC-Middletown-OH = 1.4 TPY; CC-BurnsHarbor-IN = 78 TPY (with sinter plant)
[7] 931 tpy emissions from HCl (out of 976 total HAP for the facility) are from 16 HRSG bypass/waste heat stacks at SC-Vansant-VA, a HNR facility. The footprint of the SC-Vansant-VA facility, among other factors, does not allow for HRSGs. As such, all combusted flue gases are ducted continuously (8,760 hr/yr) to the HRSG bypass/waste heat stacks. Other HNR SunCoke facilities route combusted flue gas to HRSGs and then to a spray dryer absorber (SDA) and baghouse for SO2 and PM control. The SDA also controls HCl.

[1] CC-Monessen-PA did not test for two dioxin/furan congeners (2,3,7,8-octachlorodibenzo-p-dioxin and octachlorodibenzofuran) due to an omission in the CAA 114 request instructions. Default emission factors were used instead for this facility. See the Data Memorandum.[2]
2 While Erie Coke data was used to develop foundry emissions for the Coke PQBS NESHAP RTR, because the facility permanently closed after submitting the CAA 114 request, the data for this facility was not modeled for risk purposes.
[3] Despite a conscientious testing effort, the CC-Monessen-PA Quench Tower Stack results were not able to be used. See the Data Memorandum[2] for more explanation.

4.0	EPA METHOD 303 DATA

      For the Coke Oven Batteries NESHAP sources (charging, doors, lids, and offtakes), EPA Method 303 data obtained from responses to questions in the 2022 CAA 114 request were used with the benzene-soluble organic (BSO) estimating procedures from AP-42 (EPA, 2001b) to calculate COE from each source. The COETF provided EPA Method 303 data for the facilities not included in the CAA 114 request as part of their review. Relevant documents are included in Coke PQBS NESHAP docket, (EPA-HQ-OAR-2002-0085). Table 26 summarizes the EPA Method 303 charging, door, lids, and offtakes leak data and the Coke Oven Batteries NESHAP limits. Table 27 shows the allowable emissions (tpy) before and after lowering the leak limits from doors, lids, and offtakes for each of nine ByP facilities. Table 28 shows the ratio of allowable-to-actual emissions for leaking doors. Table 29 shows actual COE (TPY) from ByP facility door, lids, and offtake leaks and charging emissions compared to allowable emissions under the Coke Ovens Batteries NESHAP, by facility and total for ByP industry. Table 30 summarizes the average opacity observed for CAA 114 compared to allowable. Appendix D provides battery-specific door leak emissions information.

[1]All facilities except CC Middletown-OH are subject to the LAER 1/1/2010 limits. CC Middletown-OH is subject to the MACT Track RTR 7/2005 limits. 
[2]Tall doors are doors greater than 6 meters (20 ft) in height. "All other" doors are either not tall or not at a foundry coke facility. HNR facilities are not permitted to have any leaking doors and do not have lids or offtakes.
[3] Three of four batteries at CC Follansbee WV are "all other" with door limits of 3.3% and the fourth battery is "tall" with door limit of 4.0%. Data presented for both.
[4] Eight of the 10 batteries at USS Clairton PA are "all other" with door limits of 3.3% and two batteries are "tall" with door limits of 4.0%. Data presented for both.

[a] Door emissions are calculated using the alternate equation.
[b] For doors, two limits apply in the current rule: 4 percent leaking doors for tall ovens (equal to or greater than 6 meters or 29 feet) and 3.3 percent leaking doors for all other shorter ovens (less than 6 meters). c For facilities with coke production capacity more than 3 million tpy coke, proposed limits from doors are 1.5 percent leaking doors for tall ovens and 1.0 percent leaking doors for all other shorter ovens; for facilities with coke production capacity less than 3 million tpy coke, proposed limits from doors is 3.0 percent leaking doors for all doors sizes.

[1] CC = Cleveland Cliffs. BLU = Bluestone. SC = SunCoke. USS = U.S. Steel.
[2] ByP = ByP; HNR = heat and/or nonrecovery.	
[3] HAP emissions have been adjusted for nondetected values.
[4] Includes category emissions from ByP pushing, ByP combustion (battery) stack, HNR operations (HNR pushing, HRSG main stack, HRSG bypass/waste heat stack), quench towers and fugitive pushing.
[5] Includes noncategory emissions from Coke Oven Batteries NESHAP sources (charging, doors (using original equation), lids, offtakes, charging), boilers, flares, 40 CFR part 61 subpart L NESHAP ByP chemical plant, co-located II&S facilities, and other operations. 
[6] Co-located II&S (noncategory) emissions: CC-Middletown-OH = 1.4 TPY; CC-BurnsHarbor-IN = 78 TPY (with sinter plant).
[7] 931 tpy emissions from HCl (out of 976 total HAP for the facility) are from 16 HRSG bypass/waste heat stacks at SC-Vansant-VA, a HNR facility. The footprint of the SC-Vansant-VA facility, among other factors, does not allow for HRSGs. As such, all combusted flue gases are ducted continuously (8,760 hr/yr) to the HRSG bypass/waste heat stacks. Other HNR SunCoke facilities route combusted flue gas to HRSGs and then to a spray dryer absorber (SDA) and baghouse for SO2 and PM control. The SDA also controls HCl.
