SUBJECT:	Coke Ovens Risk and Technology Review: Data Summary
_________________________________________________________________________________________
1.0	INTRODUCTION AND BACKGROUND
This memorandum describes the data acquired to support 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) and technology review of Coke Ovens (40 CFR part 63, subpart L). 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 Coke (PQBS) subpart CCCCC 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. The MACT for the Coke Ovens, subpart L, 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, subpart L, was promulgated on April 15, 2005 (72 FR 19992).
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. 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 RTR was due in 2011. The technology review of Coke Ovens, subpart L, NESHAP was due in 2013. 
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 ByP 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). ByP 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 by-product (ByP) plants, gases are sent to a chemical recovery plant that recovers chemicals and other by-products for sale and also cleans the coke oven gas (and is regulated under 40 CFR part 61, subpart L NESHAP); for nonrecovery plants (i.e., no chemical recovery) with heat recovery, the oven gases are sent to a heat recovery steam generator that produces power for sale and also to units that perform gas cleaning; for nonrecovery plants without heat recovery, oven exhaust gases are released to the air through waste heat stacks. 
The purpose of this memorandum is to describe the emissions and related data obtained for coke production facilities and their emission units, the review and quality control (QC) checks performed on the data; and development of the emission estimates used in the Coke Oven Emissions and Risk Modeling Databases. See the memorandum titled HAP Emissions from Coke Oven Facilities (EPA, 2023) for summaries of the emissions developed for the sources. See below for the table of contents and a list of abbreviations used.

2.0	DATA USED TO DEVELOP THE COKE OVEN EMISSIONS DATABASE
The primary sources of data for the Coke RTR were the responses to two CAA section 114 requests (Coke 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. The EPA sent out the Coke 114 requests under the authority of section 114 of the CAA (42 U.S.C. 7414) to acquire the necessary data for the RTR for Coke PQBS and the technology review for Coke Ovens, subpart L. The questionnaire portion of the Coke 114 requests included questions pertaining to inventory, process, and control device information for the emission units at the coke facilities. The source test request portion of the Coke 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 Coke 114 requests and responses received by the EPA are included in dockets for both coke ovens rules, subparts CCCCC and L (Docket ID No.'s EPA-HQ-OAR-2002-0085 (subpart CCCCC); and Docket ID No.'s EPA-HQ-OAR-2003-0051 (subpart L)).
Table 1 lists the coke facilities and companies that were operating in 2016 and 2022, the type of coke they produced, whether the facilities submitted data and/or performed source testing in response to the Coke 114 requests, and the estimated typical annual coke production. 
      The questionnaire portion of the 2016 Coke 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 2020); ArcelorMittal Burns Harbor LLC; ArcelorMittal Monessen LLC; ArcelorMittal Warren LLC; Erie Coke Corporation; DTE Energy Services, Inc.; Sun Coke Energy, Inc. (which owns three of the coke facilities receiving the 2016 Coke 114 request) and U.S. Steel Clairton. There are four other operating coke facilities that did not receive the 2016 Coke 114 request that are currently operating (or on stand-by): ABC Coke; Bluestone Coke; Sun Coke Indiana Harbor Coke; and SunCoke Jewell Coke and Coal. The test request portion of the 2016 Coke 114 request was sent to seven of the 11 facilities. Table 2 shows the details of the 2016 CAA section 114 request in terms of companies that received the request and the parts of the request they were requested to do. In 2020, Cleveland-Cliffs Inc. acquired the AK Steel: Follansbee, WV (Mountain State Carbon) and Middletown, OH cokemaking facilities and the ArcelorMittal USA LLC: Burns Harbor, IN; Monessen, PA; and Warren, OH cokemaking facilities. 
      
      The questionnaire portion of the 2022 Coke 114 request was sent to six companies that included eight facilities at coke companies operating in 2022: ABC Coke; Cleveland-Cliffs, Inc. (3 facilities); DTE Energy Services, Inc.; Sun Coke Energy, Inc. (2 facilities), U.S. Steel, and Cokenergy. The test request portion of the 2022 Coke 114 request was sent to eight facilities. Table 3 shows the companies and facilities that received the 2022 114 request and the parts of the request applicable to each facility.
      
The 2016 and 2022 Coke 114 requests included request for test data, along with physical and operating information about the emission units, were used to populate the Coke Oven Emissions Database. The emissions in the database, along with modeling release point information such as stack heights, air flowrates, and geographical locations, were used to develop the Coke Oven Risk Modeling Database for estimating the residual risk after implementation of the 2003 MACT standards for the Coke PQBS source category. The emissions data are also available to be used for developing any new MACT standards, if appropriate. The emissions data in the two databases -- emissions vs. modeling -- were almost identical except in the treatment of test measurements that were below the detection limit (BDL), which are described below in detail in Section 2.9. Development of emission data for all coke facilities and their processes are described in detail below. 
Appendix A contains a summary of the facility responses to the Coke 114 request Questionnaire. Appendix B contains the Coke Oven Emissions Database and other relevant information, such as tables of individual HAP emissions reported as Total D/F, PAH, and VOHAP in Section 4. Appendix C contains the Coke Oven Risk Modeling Database.

Coke 114 Request Questionnaire Responses
The Enclosure 1 questionnaire portion of the 2016 Coke 114 request was composed of the following parts:

 	Owner Information
II.		General Facility Information
III.		Regulatory Information
IV.		Process Flow Diagrams and Plot Plans
V.		Emission Points
VI.		Process and Emission Unit Operations
VII.		Air Pollution Control and Monitoring Equipment
VIII.		Economics/Costs
IX.		Startup and Shutdown
X.		Management Practices 
   
The Enclosure 1 questionnaire portion of the 2022 Coke 114 request was composed of the following parts: 

Part A. Background Facility Information from 2016 114 Request  -  Verify and Update, or Provide New
Part B. Coke By-Product Recovery Plants
Part C. Coke Oven Doors, Lids, Offtakes, and Charging at By-product Coke Oven Facilities
Part D. Coke By-product Battery Stack Opacity Data
Part E. Miscellaneous: Emergency Battery Flares; Community Issues; Paperwork Reduction Act Estimates

Specific information about the HAP-emitting process units was provided by coke companies in the 2016 Coke 114 request Enclosure 1 questionnaire Parts IV-VI and the 2022 Coke 114 request Enclosure 1 questionnaire Part A. The information about HAP-emitting units formed the basis of the Coke Oven Emissions Database. Coke facilities also provided the operating hours of each unit, stack diameters, stack heights, exhaust velocity, exhaust temperature, stack latitude and longitude, and other information related to their operations or HAP emissions at the facility that were used in the Coke Oven Risk Modeling Database (see Section 5 and Appendix C).
The primary HAP-emitting PQBS operating units at coke facilities are: pushing (ByP and HNR), battery stacks (ByP only), heat recovery steam generator (HRSG) main stacks (HNR only), HRSG bypass/waste heat stacks (HNR only), fugitive pushing emissions from the ovens (ByP and HNR), and quench towers (ByP and HNR). The other HAP emissions operating units at coke facilities are: Coke Ovens, subpart L, sources: charging (both ByP and HNR); ByP lids, doors (on both coal (push) and coke sides of the oven), and offtakes; ByP chemical recovery plants; boilers; flares; II&S (40 CFR part 63, subpart FFFFF) co-located sources; and other miscellaneous units not in the coke source categories. Table 4 summarizes the number of Coke PQBS units of each type at the coke facilities that are represented in the Coke Oven Emissions Database that were identified through the Coke 114 requests and discussions with industry representatives. Note that the number of units in Table 4 and the number of modeling release points in the Coke Oven Risk Modeling Database do not have a one-to-one correspondence because of some units that exhaust to multiple release points and multiple units that combine into one release point or are modeled as if combined through one release point. Table 5 summarizes the number of primary noncategory units of each type at the coke facilities that are represented in the Coke Oven Emissions Database.

Data for multiple runs in each test were averaged together for an overall average for the source test. Where possible, emission factors were calculated in pounds per ton (lb/ton) or lb/mmscf using the emission rate (lb/hr) and either coke produced during test (tph), wet coal charged during test (tph), or COG burned during test (mmscf/hr). 
Speciation Factors
Speciated Chromium Emissions Estimates
For facilities that measured total chromium for the Coke 114 requests with EPA Method 29, the total chromium emissions were speciated into two chromium species for risk modeling purposes in the Coke Oven Emissions Database, as follows: Chromium III and Chromium VI (Pope, A., 2016). Default chromium speciation factors are typically used in risk modeling for industrial sources unless information is provided otherwise. Table 8 shows the chromium speciation factors used for the Coke Oven Emissions Database and Coke Oven Risk Modeling Database. Speciated emissions were calculated as follows: 
Total Chromium Method 29  *  Speciation Factor Chromium Specie  =  Speciated Chromium Emissions Chromium Specie

Speciated Mercury Emissions Estimates 

For facilities that measured total mercury for the Coke 114 requests with EPA Method 29, the total mercury emissions were speciated into three mercury species for risk modeling purposes in the Coke Oven Emissions Database, as follows: elemental gaseous, gaseous divalent, and particulate divalent mercury (EPA, 2020). Default mercury speciation factors are typically used in risk modeling for industrial sources unless information is provided otherwise. Table 9 summarizes the mercury speciation factors used for the Coke Oven Emissions Database and Coke Oven Risk Modeling Database. Speciated mercury emissions were calculated as follows:

 Total Mercury Method 29  *  Speciation Factor Mercury Specie  =  Speciated Mercury Emissions Mercury Specie

Multiple Stacks in the Coke Oven Emissions Database
For some coke process units, there are multiple stacks. For the emissions and modeling databases, the emissions were split between each stack. Table 10 lists the units that had multiple stacks.

Dioxins/Furans Unit Conversions Coke Oven Emissions Database
Emissions of 17 individual dioxin/furan congeners were required to be tested in the Coke 114 requests for purposes of estimating health risk. These 17 specific dioxin/furan congener mass values reported in the laboratory analysis of the test reports were compiled and converted to nanograms per dry standard cubic meter (ng/dscm) and lb/hr emissions values. The 17 dioxin/furan congener values, expressed as mass rates, were entered in the Coke Oven Emissions Database for each facility and unit. The mass rates are used in the risk assessment.
The 17 specific dioxin/furan congener mass values also were converted to 2,3,7,8-TCDD toxic equivalency (TEQ) values using the 2005 World Health Organization (WHO) toxicity equivalence factors (TEF). (EPA, 2010) The 17 congener TEQ values then were summed to calculate a total TEQ value for each stack test run in the Coke Oven Emissions Database. Total TEQ toxicity values are used to establish MACT, if needed, but not for risk modeling. Table 11 lists the 17 specific dioxin/furan congeners of interest and the corresponding WHO 2005 TEF.

Data Quality Classifications and Treatment of Non-detected Values for Data Obtained via Test Methods with Multiple Fractions
The tests for metal HAP (EPA Method 29) include numerous test fractions and containers that are isolated for analytical purposes, as follows: 
 Front Half (all HAP metals), Fraction 1: Container 1 filter, Container 2 acetone probe rinse, and Container 3 acid probe rinse
 Back Half (all HAP metals), Fraction 2A and Fraction 2B: Container 4 HNO3/H2O2 (nitric acid/ hydrogen peroxide) impingers
 Back Half (Hg Only), Fraction 3A: Container 5A HNO3
 Back Half (Hg Only), Fraction 3B: Container 5B KMnO4/H2SO4 (potassium permanganate/sulfuric acid) absorbing solution
 Back Half (Hg Only), Fraction 3C: Container 5C HCl rinse and dilution
For any test fractions in the metal HAP tests where the laboratory results were classified as BDL, the method detection limit (MDL) or similar value was used as the mass of the fraction in the Coke Oven Emissions Database, as per EPA protocol for developing emissions estimates that potentially could be used to develop standards. For risk assessment purposes and in this memorandum, BDL data are handled differently, as described below in Section 2.9, The entire run was considered BDL only if all fractions of a test run were BDL. Similarly, the entire run was considered ADL only if all fractions of a test run were ADL. If there was a mix of fractions classified as either BDL or ADL in a run, then the run was labelled DLL. Note that only tests with more than one fraction could be possibly classified as DLL. For pollutants that did not have multiple fractions in the testing, the data was classified as either ADL or BDL, for mass values above or below the MDL, respectively.
 
       The tests for dioxin/furans (EPA Method 23) measures multiple individual dioxin/furan congeners. For each congener, the run was classified as BDL if the congener mass was below the Estimated Detection Limit (EDL). For each congener mass that was below the EDL, the EDL mass was used for the fraction/congener mass in the Coke Oven Emissions Database and in emissions calculations for total TEQ. Like the situation with the HAP metals test, the total TEQ value is comprised of multiple congeners that comprise the total TEQ mass in each run. Therefore, like HAP metals, the run was classified as BDL only if all the individual congener masses were below the EDL and the test runs data are classified ADL only if all congeners were above the EDL. The runs are considered DLL if one or more congeners, but not all, were below the EDL.
       
Treatment of BDL, DLL, and ADL Values Used for MACT Floor and APCD Cost Effectiveness Calculations vs. Coke Oven Risk Modeling 
      In the Coke Oven Emissions Database, for stack run data where values were at or below detection, the MDL or similar value was used for the run/fraction mass, as per EPA protocol for developing emissions estimates that potentially could be used to develop emission standards. (See details in Section 2.8 above). This type of data is classified as data that is "not adjusted for nondetected" values and was used for the calculation of MACT limits and estimates of air pollution control device cost effectiveness in the "Maximum Achievable Control Technology Standard Calculations, Cost Impacts, and Beyond-the-Floor Cost Impacts for Coke Ovens Facilities under 40 CFR Part 63, Subpart CCCCC" memorandum . In order to provide emissions for the Coke Oven Risk Modeling Database, for run data below detection, the emissions for the run were converted to half of the MDL (or EDL) for use in developing the test run value, as per EPA policy for performing risk assessments. This type of data is classified as "adjusted for nondetected" values. Both sets of data can be found in the Coke Oven Emissions Database, whereas only "adjusted for nondetected" data are used in the Coke Oven Risk Modeling Database. Note that for test runs classified as "DLL" or "ADL," there were no adjustments made to the test run values for either database. Although both "adjusted" and "not adjusted" for nondetected data are in the Coke Oven Emissions Database, only "adjusted for nondetected" data are shown in this memorandum and the Coke Oven Risk Modeling Database. 
       
3.0	COKE 114 REQUESTS DATA QUALITY CONTROL (QC) CHECKS 
After the data were compiled into the Coke Oven Emissions Database and appropriate conversions and calculations were made, as described above in Section 2.4, several rounds of review were performed by both the EPA project team and representatives from the coke industry to ascertain the accuracy of reported data and subsequent calculations. See Appendix B for all data relevant to emission estimates and the calculations performed (with supporting documents included in Coke PQBS docket (EPA-HQ-OAR-2002-0085). A final QC was performed by the risk database QA staff at the EPA. 
 3.1	Internal EPA QC Checks
 3.1.1 Laboratory Report QC for D/F
A review of the laboratory reports for dioxin/furan Coke 114 requests Enclosure 2 stack test data was performed to confirm that emissions were calculated correctly. The mass values from the laboratory reports were used to calculate the emissions and compared to the reported dioxin/furan emissions. 
 3.1.2 Inadvertent Omitted HAP
There were a few HAP for which Coke 114 requests Enclosure 2 stack test data was not obtained. These include perylene and total OCDD and OCDF. Table 12 lists the HAP and their sources omitted from the Coke 114 requests responses. The circumstances of the omissions are described below.

Perylene: 
USS Clairton, PA noted in their stack test reports that that the compound perylene had not been subjected to Maxxam's standard validation procedure for this matrix; as such, no perylene was reported for their samples for 2016 Coke 114 request submissions. 

Total OCDD and Total OCDF:
An inadvertent omission was made in the list of HAP in 2016 Coke 114 request Enclosure 2 for octachlorodibenzo-p-Dioxin (Total OCDD) and octachlorodibenzofuran (Total OCDF) dioxin/furan congeners. Some facilities still had their labs analyze for Total OCDD and Total OCDF congeners, while other facilities followed the exact list of HAP in the 2016 Coke 114 request Enclosure 2 and, therefore, did not analyze for Total OCDD and Total OCDF.

 3.1.3 Facility and/ or Unit Operating Status Changes after 2016 Coke 114 Request Data Received
The Erie Coke facility received the Coke 114 request and conducted testing from August through October 2016 on several units: ByP Pushing, ByP Battery Stack, and Boiler Stack. However, as work was being finalized for developing coke emissions for the coke industry, the EPA was notified that the Erie Coke facility was being shut down in late 2019. Therefore, the emissions for Erie Coke were used, as planned, to develop emission factors for other coke facilities that produce foundry coke and did not perform testing, but the Erie Coke units and emissions were not included in the Coke Oven Risk Modeling Database. Appendix D summarizes the Erie 2016 Coke 114 request data that were received. 
      In 2020, Cleveland-Cliffs Inc. acquired the AK Steel: Follansbee, WV (Mountain State Carbon) and Middletown, OH cokemaking facilities and the ArcelorMittal USA LLC: Burns Harbor, IN; Monessen, PA; and Warren, OH cokemaking facilities. 
The Bluestone Birmingham, AL; Cleveland Cliffs Follansbee, WV; and Cleveland Cliffs Middletown, OH facilities were not operating during the development of the 2022 Coke 114 request and did not receive the request. 
 3.1.4 Suspect Data Evaluations
Early in the development of the Coke Oven Emissions Database, suspect data were identified based on test report comments. The EPA test method experts reviewed the suspect data and made the decisions to include or not include the data in the Coke Oven Emissions Database. Table 13 below summarizes the Coke 114 requests data that was not included in the Coke Oven Emissions Database.

The EPA did not use CC-BurnsHarbor-IN SW 846 0031 methylene chloride data. Methylene chloride (MeCl2) results for all condensate samples were much higher than anticipated. It is believed that cross contamination occurred between the Method 23/0010 MeCl2 samples and the Method 0031 condensate samples as these samples were transported to Maxxam Analytics, Inc., in the same batch. In addition, the methylene chloride that was used in the field recovery of Method 23/0010, was in close proximity to where the Method 0031 condensate samples were recovered. Consequently, the Method 0031 condensate data was not considered representative of actual emissions from the source.

At 00:01 on 10/2 (p 256), the formaldehyde spiked as high as 65 ppm. The moisture increased to an average of 6% on that run, also measured by the FTIR. It appears they did not have anything else going on at the same time. The average flow rate was used for all three runs vs an independent measurement during the test run. 

EPA emailed facility Mon 1/9/2023 5:37 PM to inquire if the test was conducted during normal operations vs a small upset. The facility has not provided a response. 

Run 2 was an outlier when tested with all other formaldehyde runs and was not used for MACT or Cost calculations, but was in the risk modeling file. 

 3.2	Coke Industry Review of Coke 114 Request Data 
      Numerous reviews of the source emissions from the Coke 114 request data were performed by the facilities in the coke industry. Beginning in September 2019, the EPA sent the coke industry their processed data to review, first individually to each facility. In August 2020, the EPA sent the draft of the combined Coke 114 request data to the whole industry with all facilities' data. The EPA continued to work with industry to finalize and correct the emission estimates. 

4.0	COKE OVEN EMISSONS DATABASE
      The Coke Oven Emissions Database, and other information pertinent to the modeling of HAP emissions that were requested in the Coke 114 request (e.g., stack diameter, stack height, and operating hours), was developed in part to provide a repository of emissions data to be used to populate the Coke Oven Risk Modeling Database (described in Section 5). The following sections discuss the data from the Coke Oven Emissions Database used to develop the emissions for the Coke Oven Risk Modeling Database ("adjusted for nondetected" data). All emission calculations and supporting files are included in Appendix B along with the complete Coke Oven Emissions Database.
 4.1	Actual Annual Emissions for Coke PQBS Source Category
      The HAP emissions from the 2016 and 2022 Coke 114 request Enclosure 2 and 1998 uncontrolled stack test data for fugitive pushing HAP profile (EPA, 1999a and EPA, 1999b) were used to develop the Coke Oven Emissions Database "actual" annual HAP emissions estimates for all HAP-emitting Coke PQBS units at coke facilities (pushing, battery combustion stack, HRSG main stack, HRSG bypass/waste heat stack, quench tower, and fugitive pushing). All emissions, calculations, and supporting files are described in Appendix B.). The Coke Oven Emissions Database was then used to populate the Coke Oven Risk Modeling Database described in Section 5.
      
 4.1.1 Emissions Developed from 2016 and 2022 Coke 114 Request Enclosure 2 Stack Test Data
      A number of Coke PQBS sources were requested to conduct testing as per the 2016 and 2022 Coke 114 request Enclosure 2 stack tests. Table 14 summarizes the units for facilities from which the EPA received 2016 and 2022 Coke 114 request Enclosure 2 stack test data that were used to estimate emissions from other facilities in the industry and other units at the facilities that were not tested.

[1] CC-Monessen-PA did not test for OCDD and OCDF due to an EPA omission. Default emission factors were used instead for this facility. See Section 3.1.2
2 While Erie Coke data was used to develop foundry emissions for the Coke PQBS RTR, because the facility is now permanently closed, the data for this facility was not modeled.
[3] Despite a conscientious testing effort, the CC-Monessen-PA Quench Tower Stack results were not able to be used. See Section 3.1.4, for more explanation.

                                          
	Table 15 summarizes the calculations used to develop coke oven facility emission estimates in tons per year (TPY) from 2016 and 2022 Coke 114 request stack test data. The individual components of the calculations are described in the sections that follow.

4.1.1.1 Emission Factors Developed from Coke 114 Requests Enclosure 2 Stack Test Data

      The 2016 and 2022 Coke 114 request Enclosure 2 stack test data ("adjusted for nondetected") was used to create default industry emission factors by coke type (i.e., foundry coke vs. blast furnace coke), process ID and pollutant to use for all other facilities and units that were not required to test to develop the Coke Emissions Database. The emissions for Erie Coke were used to develop emission factors for facilities that produce foundry coke (see Section 3.1.3). Tables 16 - 19 summarize the emission factors and units of measurement (UOM) for each default industry emission factor per process ID and coke type, as applicable. See Appendix B for a complete listing of the units for each facility and individual HAP emission factors used in the Coke Oven Emissions Database.

4.1.1.2 Similar Units Used with Surrogate Data
      
      The EPA used the 2016 and 2022 Coke 114 request Enclosure 2 stack test data ("adjusted for nondetected") for similar units at the test facilities as "surrogate" data. Table 20 summarized the units where data from similar units were used for those units at the same facility that were not required to test.

4.1.1.3 Coke Production and Operating Hours Data
      
      The calculation of emissions for coke process units from emission factors required knowledge of coke production or operating hours, depending on the units of the emission factors, i.e., lb HAP per ton coke produced or lb HAP per hour. The annual coke facility production and operating hours obtained for this purpose are summarized in Tables 21 and 22 below, respectively. The information was obtained from the 2016 Coke 114 request, previous EPA reports, or communication with the COETF.

4.1.1.4 Control Device Efficiency Corrections 
      
      The emission factors for the EP-9 HNR Pushing (CD) units were developed from test data at SunCoke's Middletown-OH facility from units with a multiclone control device. Although two other SunCoke facilities (Haverhill and Franklin Furnace) also use multiclones, the SC-Vansant-VA facility utilizes cokeside sheds and the SC-EastChicago-IN facility utilizes a baghouse for their pushing controls. As such, a control device efficiency correction was calculated for these two facilities and applied to the emission factors developed from multiclone tests. In the SunCoke permit application for Middletown, the estimated particulate control efficiency of the multiclone is 98% (based on AP-42 factors in Table 12.2-6 and AP-42, Appendix B.2, Figure B.2-1  (EPA, 2001b). Table 23 summarizes the control device efficiency correction factors used for cokeside shed and baghouse pushing controls.

4.1.1.5 Oven to HRSG Bypass/Waste Heat Stack Adjustment
      
      The EPA estimated emissions for HRSG bypass/waste heat stacks based on the emission factors developed from source testing at the SunCoke Gateway facility in Granite City, IL, in units of lb HAP/hr. For the SC-Vansant-VA facility, this approach was adjusted to account for the SC-Vansant-VA facility having fewer ovens per stack as compared to the SunCoke Gateway facility. The SC-Vansant-VA facility has 143 ovens and 16 HRSG bypass/waste heat stacks resulting in approximately 9 ovens per stack. However, the SC-GraniteCity-IL facility has 120 ovens and 6 HRSG bypass/waste heat stacks resulting in 20 ovens per stack. Therefore,  the SC-Vansant-VA stack emissions were multiplied by the ratio of the number of ovens per stack for each facility, or 9/20, to account for the lower number of ovens per stack at SC-Vansant-VA. 
      
 4.1.2 Fugitive Pushing Emission Estimates
      The basis for calculating metal HAP and PAH "surrogate" emissions for fugitive pushing emissions from the ovens were data from two stack tests: Arcelor Burns Harbor in 1998 (EPA report EPA-454-R-99-001a; Docket No. A-2000-34, Document No. II-A-15) (EPA, 1999a) and ABC Coke in 1998 (EPA report EPA-454-R-99-002a; Docket No. A-2000-34, Document No. II-A-16) (EPA, 1999b). The test data from ArcelorMittal Burns Harbor applies to blast furnace coke facilities (ByP and HNR), while the test data from ABC Coke applies to foundry coke facilities. The COETF provided battery-specific capture efficiencies for 27 batteries at nine facilities (COETF, 2021a). A capture efficiency of 95 percent was used as default for facilities that did not provide specific capture efficiencies per battery, where all data were <4% opacity by Method 9. Table 24 summarizes the capture efficiencies used for each battery and the source.

[1] Where more than one battery is listed, fraction applies to each battery.
[2]The COETF (2021a) provided the documentation for the pushing capture efficiencies in most cases. A value of 0.95 was used as a conservative default factor where no information was available. 
      
      
      The annual battery coke production values from the 2016 Coke 114 request Enclosure 1 from Table 21 above, as revised by industry where applicable, also were used in the following equation to calculate TPY emissions for metal HAP and PAHs: 
      
      HAPi = FPM * SFi * (1  -  Capture) / Coke Pushed * Coke Production 
      
      Where:
      HAPi = Emission rate of HAP i (ton/yr)
      FPM = Uncontrolled filterable PM emission rate (lb/hr) 
      SFi = Speciation factor of HAP i (dimensionless)
      Capture = Pushing capture efficiency (fraction) 
      Coke Pushed (ton/hr) from ABC Coke and ArcelorMittal Burns Harbor stack tests
      Coke Production (ton/yr) 
      
      For acid gases, semi-volatile HAP, and D/F, the industry default emission factors, as described in Section 4.1.1, were used with the pushing capture efficiencies provided by industry in the following equation to calculate TPY "surrogate" emissions for Acid Gases, Semi-Volatile HAP and D/Fs. 
      
      HAPi = ((HAPi EF * Coke Production / 2000) / Capture) * (1 - Capture)
      
      Where:
      HAPi = Emission rate of HAP i (ton/yr)
      HAPi EF = Industry default emission factors (lb/ton coke)
      Coke Production (ton/yr) 
      Capture = Pushing capture efficiency (fraction) 

 4.2	Actual Annual Emissions for Noncategory Emissions
      The HAP emissions from the 2016 and 2022 Coke 114 request Enclosures 1&2 and EPA's 2017 National Emission Inventory (NEI)/ Emission Inventory System (EIS) data were used to develop the Coke Oven Emissions Database "actual" annual HAP emissions estimates for all HAP-emitting noncategory units at coke facilities. The noncategory HAP emissions operating units at coke facilities are: Coke Ovens, subpart L, sources: charging (both ByP and HNR); ByP lids, doors and offtakes; ByP chemical recovery plants; boilers; flares; II&S (40 CFR part 63, subpart FFFFF) sources, i.e., BF, BF stoves, BOPF control devices, ladle metallurgy, hot metal transfer skimming and desulfurization, sinter plant windbox, sinter plant discharge end, and BF cooling tower; and other miscellaneous units not related to coke manufacturing (e.g., process heaters, metal finishing, steel pickling, annealing furnaces, coating line pot heaters, reheat furnaces, thermal coal dryers, etc.). All emission calculations are show in Appendix B. Supporting files are included in the Coke PQBS docket (EPA-HQ-OAR-2002-0085). The Coke Oven Emissions Database was used to populate the Coke Oven Risk Modeling Database described in Section 5.

      The EPA used the 2016 Coke 114 request Enclosure 2 stack test data to create default industry emission factors per coke type (i.e., foundry coke vs. blast furnace coke), per process ID, and per pollutant, to use for all other units that were not required to test as "surrogate" data. Tables 27 and 28 summarize the emission factors and UOM for each default industry emission factor per process ID.

      For the Coke Ovens, subpart L, sources (ByP charging, doors, lids, and offtakes), Method 303 data obtained from responses to questions in the 2016 and 2022 Coke 114 request Enclosure 1 were used with the benzene-soluble organic (BSO) estimating procedures from AP-42 (EPA, 2001b) to calculate coke oven emissions (COE) from each source. The COETF provided Method 303 data for the non-114 request facilities as part of their review (see data in Appendix B). Relevant documents are included in Coke PQBS docket, (EPA-HQ-OAR-2002-0085). The calculated emissions for doors were divided by two to represent the emissions from doors on each side of the battery (i.e., push side and coke side) for modeling purposes. Table 32 summarizes the equations used to estimate emissions for Coke Ovens, subpart L, sources.

           Units with Coke 114 Request Enclosure 1 Data (EPA, 2003)
                               Emissions Source
                            Calculation Methodology
Charging
BSOcharging = VE x (charges/year) x (0.0093 lb BSO/10 seconds)
Where,
BSOcharging = BSO emission rate from charging (lb/yr)
VE = average seconds of visible emissions per charge
Doors
BSOdoors = ND x (PLDYARD/100) x (0.04 lb/hr) + 
                          ND x (6% PLDBENCH/100) x (0.023 lb/hr)
where,
BSOdoors = BSO emission rate from door leaks (lb/hr)
ND = total number of doors on battery
PLDYARD = percent leaking doors from the yard as determined by Method 303
PLDBENCH = 6% percent leaking doors from the bench (EPA, 2008)
Lids
BSOlids = NL x (PLL/100) x (0.0075 lb/hr)
where,
BSOlids = BSO emission rate from lids (lb/hr)
NL = total number of lids on battery
PLL = average percent leaking lids
Offtakes
BSOofftakes = NO x (PLO/100) x (0.0075 lb/hr)
where,
BSOofftakes = BSO emission rate from offtakes (lb/hr)
NO = total number of offtakes on battery
PLO = average percent leaking offtakes
Note: Equations are taken from AP-42 (EPA, 2001b)
      
      
      For charging, the "VE" values (average seconds of visible emissions per charge) came from the Coke 114 request Enclosure 1 responses or were provided by COETF as part of their review. The "charges/year" values also were obtained from the Coke 114 request Enclosure 1 responses or provided by COETF as part of their review. For doors, the "ND total number of doors on battery" values were obtained from responses to the Coke 114 request Enclosure 1 or were provided by COETF as part of their review. The values for "PLD percent leaking doors as determined by Method 303" were obtained from the Coke 114 request responses to Enclosure 1 or were provided by COETF as part of their review. For lids, the "NL = total number of lids on battery" values were obtained from the responses to the Coke 114 request Enclosure 1 or were provided by COETF as part of their review. The "PLL = average percent leaking lids" values were obtained from responses to the Coke 114 request Enclosure 1 or were provided by COETF as part of their review. For offtakes, the "NO = total number of offtakes on battery" values came from Coke 114 request Enclosure 1 responses or were provided by COETF as part of their review. The "PLO = average percent leaking offtakes" values were obtained from Coke 114 request Enclosure 1 responses or were provided by COETF as part of their review. 
      
Table 33 through 40 shows the data calculation elements used to estimate COE emissions (in TPY) for charging and leaks from doors, lids, and offtakes for each battery at the coke facilities, and results of the calculations. Tables 41 and 42 summarize the results for the coke facilities as overall facility averages along with the allowable limits and facility average as a percent of the limit.

[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 4 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.

 4.2.4 2017 Noncategory Sources 
      For the noncategory sources of coke ByP chemical recovery plants and excess coke oven gas flares, 2017 NEI/EIS data were used to develop average industry default "surrogate" emission values per pollutant. The HNR facilities do not have ByP chemical recovery plants or excess coke oven gas flares. 

      For more information on the EPA inventories used to obtain noncategory data, see 
https://www.epa.gov/air-emissions-inventories/2017-national-emissions-inventory-nei-data, https://www.epa.gov/air-emissions-inventories/emissions-inventory-system-eis-gateway. 

      For the ByP chemical recovery plant, the 2017 NEI/EIS data were compiled for applicable ByP chemical recovery plant emission sources, by facility. The industry provided updated emissions for the ByP chemical recovery plant sources, as applicable, during their review. All emissions from the individual sources in the ByP chemical recovery plant were summed to create a total for the plant per HAP. The average of each HAP was calculated to create a default facility total per HAP to be used for facilities that did not have reported HAP values. Table 43 summarizes the ByP chemical plant facility and default emissions. 
      
      For excess coke oven gas flares, 2017 NEI/EIS emission data were compiled for these sources at coke facilities. Because not all the coke facilities had flare data available, the average flare emissions for each HAP in the available coke facility data in the 2017 NEI/EIS were calculated. For facilities with more than one available HAP value in the 2017 NEI/EIS, the average emissions for each HAP from flares for the facility were calculated. The overall average emissions across all coke facilities with flare data were calculated for each HAP to create a default flare emission rate for each HAP per flare. The default flare emissions per HAP per flare were used in the Coke Ovens Emission Database for flares that did not have reported HAP data. For coke facilities with 2017 NEI/EIS HAP data for flare units, the facility flare data was used as reported. For mercury emissions from flares, the same Hg speciation factors were used for noncategory flare sources as were used for PQBS sources, as described above in Section 2.5. Table 44 summarizes the flare emissions per facility and default emissions.
      
      For the other miscellaneous units not related to coke manufacturing (e.g., process heaters, metal finishing, steel pickling, annealing furnaces, coating line pot heaters, reheat furnaces, thermal coal dryers, etc.), the 2017 NEI/EIS data were compiled and used as the actual emissions for these sources at coke facilities. See Appendix B and C for the other miscellaneous coke sources included in the Coke Oven Emissions Database and Coke Oven Risk Modeling Database. 
      
 4.2.5 Co-located II&S sources
      The CC-BurnsHarbor-IN, CC-Middletown-OH, and SC-EastChicago-IN coke facilities are co-located with the ArcelorMittal, Burns Harbor, IN; AK Steel Middletown, OH; and ArcelorMittal Indiana Harbor, East Chicago, IN II&S facilities, respectively. However, the ArcelorMittal Indiana Harbor, East Chicago, IN II&S facility has separate ownership from the co-located SunCoke Indiana Harbor Coke, East Chicago, IN, coke facility so is not included in this analysis. For the other co-located II&S sources, the actual emissions developed

 4.3	Opacity Data
      As discussed in Section 2.2, the pushing, battery combustion, boiler, HRSG Main, HRSG bypass/waste heat, and HNR charging stacks and quench towers were required to conduct opacity observations for the 2016 and 2022 Coke 114 request. Table 45 summarizes the average opacity observations for those sources.

[1] Of the 19 operating byproduct batteries at six facilities, 11 batteries are operating under normal coking and 8 batteries are operating under extended coking. Current battery stack opacity limits are: daily average of 15 percent opacity for a battery on a normal coking cycle and daily average of 20 percent opacity for a battery on batterywide extended coking.
[2] Of the 19 operating byproduct batteries at six facilities, 5 batteries are short and 14 batteries are tall. Current by-product coke oven battery with vertical flues are: average opacity for any individual push is 30 percent opacity for any short battery or 35 percent opacity for any tall battery.

 4.4	Allowable HAP Emissions for Coke PQBS and Noncategory Sources
      "Allowable" emissions are the maximum emissions that a facility or unit could emit under the current applicable rule. For Coke PQBS sources (ByP pushing (CD), HNR pushing (CD), and fugitive pushing, the allowable HAP emissions were developed from the ratio of the PM standards to actual estimated PM emissions. For the ByP battery stack, the ratio of the opacity limits (§63.7296(a) and (b)) to opacity test data for each unit were used to develop allowable-to-actual ratios for battery stacks to estimate allowable HAP emissions. For quench towers, the ratios of the quench tower limit (§63.7295(a)(i)), expressed as the concentration of total dissolved solids (TDS) in the water (1,100 mg/L), to TDS test data from the 2016 Coke 114 request were used to develop allowable-to-actual emission ratios for each unit tested. For HRSG main stacks and HRSG bypass/waste heat stacks, allowable HAP emissions were set equal to actual HAP emissions because the Coke PQBS rule does not have HAP limits for these sources.
      
      For the noncategory sources regulated under Coke Ovens subpart L (HNR charging and ByP charging, doors, lids, and offtakes, the Coke Ovens subpart L standards were used to develop allowable emissions of COE. For other noncategory sources (ByP chemical plant, flares, and "other source" process units), allowable HAP emissions were set equal to actual emissions. For ByP boiler stacks, the 2015 annual potential boiler usage (mmscf/yr) data (COETF, 2021b) were used to develop allowable HAP emissions for boilers. For co-located II&S sources, allowable HAP emissions developed for II&S RTR modeling were used. 
      
      The following sections describe the methodology used to estimate allowable HAP emissions for category and noncategory sources at PQBS Coke facilities. All allowable emission calculations and supporting files are included in Appendix B. See Appendices B and C for lists of the allowable HAP emissions in the Coke Oven Emissions and Risk Modeling Databases, respectively. 
      
 4.4.1 ByP Pushing (CD) and HNR Pushing (CD)
      Table 46 lists the type of pushing capture and control equipment used at the coke facilities. The pushing capture and controls were used to identify the applicable PM limit, to develop capture and control emissions estimates per push, and to calculate the allowable-to-actual PM and HAP ratios.

      The ratios of the Coke PQBS PM limits for pushing (§63.7290(a)) per category (as applicable) to the pushing PM test data from the 2016 Coke 114 request were used to develop allowable-to-actual ratios to estimate allowable HAP emissions for pushing units with test data. An average allowable-to-actual ratio was developed for each pushing category where multiple test data were available. The average allowable-to-actual ratios were used to assign default ratios for pushing categories to estimate allowable HAP emissions for facilities without HAP test data. Table 47 summarizes the allowable-to-actual ratios calculated from PM test data and the average allowable-to-actual PM ratios used as default values, where appropriate.

 4.4.2 EP-10 Quench Tower
      The ratios of the quench tower limit (§63.7295(a)(i)), expressed as the concentration of total dissolved solids (TDS) in the water (1,100 mg/L), to TDS test data from the 2016 Coke 114 request were used to develop allowable-to-actual emission ratios for each unit tested. Table 50 summarizes the allowable-to-actual ratios calculated for units with TDS test data . The average of the ratios was used as a default allowable-to-actual ratio for facilities that did not test. Table 51 summarizes the allowable-to-actual ratios used to estimate allowable HAP emissions for all quench tower units.

      The ratio of the opacity limits (§63.7296(a) and (b)) to opacity test data for each unit were used to develop allowable-to-actual ratios for battery stacks to estimate allowable HAP emissions. Table 52 shows the allowable-to-actual ratios calculated from units with 2016 Coke 114 request opacity test data. The averages of the allowable-to actual ratios for each type of battery stack were used as default ratios for facilities that did not test. Table 53 shows the default allowable-to-actual ratios for battery stacks, by coke and process type, that were developed from test data . Table 54 shows the allowable-to actual ratios for all battery stack units.

 4.4.4 EP-8 HNR Charging (CD)
      The ratio of the HNR PM charging limit to charging PM test data was used to develop an allowable-to-actual ratio for HNR charging for the facilities with test data. The average of these ratios was used for HNR charging units that were not tested. Table 55 shows the allowable-to-actual ratios for each unit with test data. The average of the allowable-to-actual ratios was used as a default ratio for facilities that did not test.

      Table 56 shows the allowable-to-actual ratios for all HNR charging units. For the Vansant, SC, the allowable HAP emissions were set equal to the actual HAP emissions because this facility, an existing source in 2005, was not subject to the new source MACT limit established in 2005 (70 FR 19992).

 4.4.5 ByP Charging, Doors, Lids, and Offtakes
      For ByP charging, and leaking doors, lids, and offtakes sources, the BSO estimating procedures from AP-42 (EPA, 2001b) were used to calculate COE for both actuals and allowables. Tables 57-60 summarize the  limits that were used to calculate allowable COE emissions for charging, doors, lids, and offtakes.

 4.4.6 EP-4 ByP Boiler stacks
      The COETF provided the 2015 Plantwide Boiler COG usage (mmscf/yr); 2015 coke production (TPY); and annual coke production capacity (TPY) (COETF, 2021b). These values were used to calculate the 2015 annual potential boiler usage (mmscf/yr) per boiler using the following equation: 
      
      2015 annual potential boiler usage (mmscf/yr) = 
            2015 plantwide boiler COG Usage (mmscf/yr) / 2015 coke production (TPY) * annual coke production capacity (TPY)
      
      The 2015 annual potential boiler usage (mmscf/yr) was used with the industry default emission factors per HAP (lb HAP/mmscf) to calculate allowable TPY emissions. Table 65 summarizes the ratio of allowable-to-actual emissions.

 4.4.7 Co-located II&S sources
      For the co-located II&S sources, the EPA used the allowable emissions developed for II&S RTR modeling file that are described in the memorandum "Integrated Iron and Steel Risk and Technology Review: Point Source Data Summary" and shown in Appendix B. (See also II&S Docket Item ID EPA-HQ-OAR-2002-0083-0955).

 4.5	Acute Emissions for Coke PQBS and Noncategory Sources

      Acute emissions used in EPA risk modeling are the highest emissions that might be expected in any hour during the year. Coke oven charging, pushing, and quenching operations maintain largely consistent hour-to-hour pushing rates because plants are constrained by oven capacity, coking temperatures, coking times, and plant design/equipment. Coke plants may have small deviations in short-term emission rates from annual average emission rates. 
      
      Analysis of hourly pushing records at five coke plants showed that the hourly pushing rate does not deviate significantly from the annual average pushing rate, with multipliers ranging from 1.26 to 2.06 (COETF, 2020). The individual facility data are considered proprietary and company confidential information. Based on the multiplier range of the data, an acute factor of two (2) was used to estimate acute hourly emissions from actual hourly emissions for each HAP and unit in the Coke Oven Risk Modeling Database. 
      
      For the co-located II&S sources, the EPA used the acute emissions developed for II&S RTR modeling file, as described in the memorandum "Integrated Iron and Steel Risk and Technology Review: Point Source Data Summary" (II&S Docket Item ID EPA-HQ-OAR-2002-0083-0955) and shown in Appendix B. The acute factor was also 2.0 based on the ratio of opacity limits for normal operation vs. limits allowed for one-time excursions.
      
 4.6	Coke Industry Review of the Coke Oven Emissions Database 
      In August 2020, the EPA sent all facility data to the industry with an example file of how the TPY emissions would be calculated for ByP and HNR pushing (EP-1 & EP-9), ByP battery combustion (EP-3), ByP Boilers, HNR HRSG main stacks (EP-6), HRSG bypass/waste heat stacks (EP-7), HNR charging (EP-8), and quenching (EP-10) and a writeup of assumptions and estimates for the calculation process in general. In November 2020, the EPA sent the industry several other emissions files for review including emissions developed for ByP chemical recovery plant, flares, fugitive pushing, and Method 303 data for Coke Ovens subpart L sources. The EPA continued to work with industry into early 2021 to verify the estimated emissions and calculations. All correspondence and review files are included in the Coke PQBS docket (EPA-HQ-OAR-2002-0085).
      
5.0	COKE OVEN RISK MODELING DATABASE
      The emissions developed in the Coke Oven Emissions Database were combined with other facility and unit data needed for modeling to develop the Coke Oven Risk Modeling Database, as described in the sections below. Note that the Coke Oven Risk Modeling Database contains rounded values and, as such, the emissions in this database are slightly different from the adjusted for nondetected TPY values in the Coke Oven Emissions Database, which are unrounded. 

 5.1	Facility Qualifiers
 5.1.2 Facility Location Qualifiers
      Table 66 summarizes the general facility location information compiled from the 2016 and 2022 Coke 114 request Enclosure 1 responses that were supplemented with NEI/EIS data, as necessary. All of the facilities are located in non-tribal areas and have a tribal code of 000. 

 5.1.2 Facility NAICS Codes
      The primary North American Industry Classification System (NAICS) code for each facility was identified and included in the Coke Oven Risk Modeling Database. Table 67 summarizes the primary NAICS code for each facility.
      
 5.1.3 Facility Category
      The facility category was identified based on whether the facility was a major source of HAP (only), both HAP and criteria air pollutants (CAP), or unknown. The facility category determinations were obtained from the NEI/EIS. Table 68 summarizes the facility category for each coke facility.

 5.2	Unit Qualifiers 
 5.2.1 Unit Identifications 
      The emission unit IDs, emission unit descriptions, process IDs, process descriptions, and emission release point IDs developed for the Coke Oven Emissions Database were used for the Coke Oven Risk Modeling Database. Emission release points are discussed in more detail below in Section 5.2.2.
      
      The Source Classification Code (SCC) for each unit was compiled in the Coke Oven Risk Modeling Database. A list of applicable SCCs and descriptions for the Coke PQBS source category and noncategory process units at coke facilities can be found in Appendix E. 

 5.2.2 Modeling Release Point Information by Unit
      Table 69 shows the modeling release points for the coke oven processes by their code and type used in the Coke Oven Risk Modeling Database. All sources with stacks (including quench towers) have modeling release points the same as stack emissions release points (vertical, release point type = 2). However, the release points for some emission units or collection of emission units were based on the expected aerodynamic behavior of emissions from the units (fugitive two-dimensional, release point type = 9). 
      
      The additional modeling parameters needed for stack release points are discussed below in Section 5.2.4 and 5.2.5. The additional modeling parameters needed for non-stack release points are discussed below in Section 5.2.6.
      
 5.2.3 Unit Control Information
      The 2016 Coke 114 request Enclosure 1 responses and NEI/EIS data, as necessary, were used to assign control status and control measure codes for each unit in the Coke Oven Risk Modeling Database. The control status was identified as either controlled, uncontrolled, or unknown. Table 70 shows the specific control device codes and descriptions used for control devices at coke facilities.
      
      The CAA part and section under which each unit is regulated is identified in the Coke Oven Risk Modeling Database. Table 71 shows the regulatory codes by process ID. 
      
 5.2.4 Unit Stack Parameters 
	The stack parameters for each release point in the Coke Oven Risk Modeling Database, that include height (ft), gas temperature (°F), diameter (ft), gas velocity (ft/sec), and gas flow rate (cubic ft/sec), were compiled from information in the 2016 Coke 114 request, discussions with the COETF, and NEI/EIS data. The EPA conducted an internal, independent quality assurance check on the stack parameters, as per EPA RTR protocol. Stack "default flags" were used to indicate how the stack parameters were obtained or developed. Table 72 summarizes the stack default flags used in the Coke Oven Risk Modeling Database. 
      
 5.2.5 Unit Stack Latitude and Longitude Coordinate QC
The latitude and longitude coordinates of coke facility stacks (modeling release point type = 2) and other nonstack HAP release points were mapped using the Google Maps(TM) program to verify their locations. For sources with a typical stack, the reported latitude and longitude coordinates for the base of the stack were verified visually or adjusted accordingly. In a few cases, the latitude and longitude coordinates of coke facility units submitted in the 2016 Coke 114 request were not within the facility property lines and/or were not located on operating equipment. Latitude and longitude coordinates also were missing for some of the units. In these cases, the EPA consulted directly with coke facility staff to accurately locate the units. The latitude and longitude coordinates for "Other" coke units whose data came from NEI/EIS were used as reported in the NEI/EIS. The latitude and longitude coordinates for co-located II&S sources were used as developed for the II&S RTR modeling file, which had already been through EPA review.

 5.2.6 Unit Non-Stack Parameters
For the coke process modeled as fugitive two-dimensional sources (modeling release point type = 9), i.e.., mobile charging machines, mobile pushing machines, doors, lids, offtakes, and fugitive pushing, two sets of latitude and longitude coordinates were required. Using Google Maps,(TM) the pairs of coordinates were set at the vertical midpoints of opposing sides of the source The fugitive release heights were set at the battery (building) height (ft). The fugitive length and fugitive width were set at the battery (building) length and width, respectively. The fugitive width for mobile control devices were set at the width of the stack. The fugitive width for fugitive pushing were sat at 0.9 meters (EPA, 2003). (Note. exit gas velocity, flowrate, and temperature are not needed for fugitive two-dimensional sources). Table 73 shows the fugitive two-dimensional line sources and the modeling parameters.

Notes:
--Coke side: means the side of a battery from which the coke is discharged from ovens during pushing at the end of the coking cycle.
--Push side: means the side of the battery where the pushing equipment enters the ovens at the end of the coking cycle to push the coke out of the oven. For HNR ovens, this also is called the coal side because it is where the coal is placed in the ovens at the beginning of the coking cycle to make coke from coal.
--In charging, ByP plants charge into ovens from the top of the ovens/battery, whereas HNR charge into ovens/battery at the side (e.g., coal side).

For fugitive area sources with modeling release point type = 7 (e.g., ByP chemical recovery plants) the latitude and longitude coordinates were derived from the southwest corner of the rectangle drawn around the collection of ByP chemical recovery plant units with Google Maps[TM]. (See Figure 1, below). The fugitive modeling release heights were set at the median stack height (ft) of the applicable equipment, which were provided by the COETF (supporting documents are included in Coke PQBS docket, EPA-HQ-OAR-2002-0085). The fugitive length and fugitive widths were determined from the rectangle drawn around the collection of ByP plant units with Google Maps[TM]. The fugitive angle, which is the angle between the side of the rectangle and due north on the southwest corner of the rectangle in Figure 1 below, also was established with Google Maps[TM]. Note, exit gas velocity, flowrate, and temperature are not needed for fugitive area sources. 
5.2.7 Unit Location and North American Datum Information
      A location descriptor is required in EPA modeling databases to identify the source of location data for each unit. For all coke units beside "Other," the flag of "RTR" was used in the Coke Oven Risk Modeling Database to signify that the locations were developed from 2016 Coke 114 request data for the RTR. For the "Other" coke units, the flag of "EIS" was used instead because their data and location information came directly from the NEI/EIS database. For the co-located II&S sources, the flag of "Industry" was used because the data came from industry via the II&S 114 request for the II&S RTR.
                                       
      In addition, a North American Datum code was assigned for each unit's location. For all the coke units besides "Other," the code of "002 North American Datum of 1983" was used. For the "Other" coke units, the codes of "001 North American Datum of 1927" and "003 World Geodetic System of 1984" were used, as reported in the NEI/EIS where their unit information was obtained.
                                       
 5.2.8 Unit Operating Hours
      The hours per year were compiled for each unit from 2016 Coke 114 request responses or the COETF, and supplementing with NEI/EIS data, as needed. The EPA did not model any units/facilities that required a "Closed Year" to be identified in the modeling field included in the EPA's RTR model file prototype. 

 5.3	Emissions Data Qualifiers
      The start and end dates of the emissions data are required for the EPA's RTR modeling databases. Table 74 summaries the start and end dates per data source and process ID.in the Coke Oven Risk Modeling Database.

Identification of the data source was required for the Coke Oven Risk Modeling Database. Table 76 lists the data sources and type of data per process ID in the Coke Oven Risk Modeling Database. 

 5.4	Coke Industry Review of Coke Oven Risk Modeling Database 
      In October 2020, the EPA sent, a draft of the Coke Oven Risk Modeling Database, complete with unit sources and modeling release point parameters, to the coke industry, (via the COETF) for their review for accuracy. The EPA continued to work with the industry into early 2021 to finalize the emissions, TPY calculations, and modeling release point parameters. All correspondence and review files are included in the Coke PQBS docket (EPA-HQ-OAR-2002-0085).

6.0	COKE BY-PRODUCT RECOVERY PLANT
      As discussed in Section 2.2, several sources from the coke by-product recovery plant were required to be tested under the 2022 Coke 114 Request Enclosure 2.

 6.1 Cooling Tower Inlet
	Three facilities received the 2022 coke 114 request for cooling tower inlet testing. Table 77 summarizes the facilities and their submissions. 

                   Table 77. Cooling Tower Inlet Submissions

                               Facility Comments
ABC-Tarrant-AL
Data provided - No VOHAP
Due to the lack of commercially available TO-15A analysis, both accredited and unaccredited, the approach of reporting VOHAP as
BTEX determined by EPA Method 18, as described in the EPA Risk and Technology Review (RTR) text in reference to testing HRSG, HNR, and Oil Condenser stacks was used. The unavailability of laboratories to conduct further analysis deems this the most comprehensive available approach and concurrent MDL THC values, along
with non-detect BTEX values, indicate the lack of strippable volatile organics from this source.

No Data
Between September 23, 2022, through November 15, 2022, Warren Coke's Emergency flares did not activate for a duration that required Method 22 readings per Cleveland-Cliffs' September 22, 2022 Enclosure 2 Stack Testing Schedule.  Also, per the September 22, 2022 letter, Warren Coke, under typical operating conditions, does not utilize the Excess Coke Oven Gas Flare. Therefore, Cleveland-Cliffs Warren Coke does not have any Method 22 results to submit. 
EES-RiverRouge-MI
Data
EES Coke does not have existing sample ports for COG at the inlets
of the BP Flare or any of the eight Emergency Bypass Bleeder Flares. EES Coke is providing COG analysis at a location previously communicated in the August 3, 2022 letter regarding stack testing issues. A COG sample was obtained on October 3, 2022, which coincided with two of the three BP Flare Visible Emissions (VE) observations. EES Coke obtained a sample of the COG on October 3, 2022 and had it analyzed using method T0-15.

                         COKE OVEN EMISSIONS DATABASE

The Coke Oven Emissions Database is in the accompanying Microsoft Excel(R) files. This file includes the parameters and emission data compiled from each data source and the calculations of TPY emissions. All emission calculations and supporting files are included in the Coke PQBS docket (EPA-HQ-OAR-2002-0085). Additional summary emission information can be found in the "Coke Emissions Memorandum," also in the docket to this rule.

Excel file B-1 includes only 2016 Coke CAA section 114 data.

Excel file B-2 includes only 2022 Coke CAA section 114 data.

Excel file B-3 includes 2016 and 2022 Coke CAA section 114 data for Bypass/waste heat stacks.

Excel file B-4 includes 2016 and 2022 Coke CAA section 114 data for HRSG main stacks.

Tables B-1 through B-4 below summarize the total HAP emissions (adjusted for non-detected data) for each facility along with a breakdown between Coke PQBS and noncategory source emissions and coke production capacity. Note Table B-1 and B-3 use the existing (old) door COE equation while Table B-2 and Table B-4 use the new door COE equation.

[1] AKS = AK Steel. AM = ArcelorMittal. BLU = Bluestone. SC = SunCoke. USS = U.S. Steel.
[2] ByP = By-product; 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 non-category emissions from 40 CFR part 63 subpart L sources (ByP Charging, Doors (using existing equation), Lids, Offtakes, and HNR charging), ByP Boilers, Flares, 40 CFR part 60 subpart L ByP chemical plant, co-located II&S facilities, and other operations. 
[6] Co-located II&S (non-category) 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 heat recovery steam generator (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.
