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.

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.

 4.4.3 EP-3 ByP Battery (Combustion) 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. 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).

 4.4.6 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.

      The emission calculation method is also required to be identified for the Coke Oven Risk Modeling Database. Table 75 summarizes the emission calculation method code per process ID. 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.
USS-Clairton-PA
No Data
U. S. Steel will not intentionally activate the Battery emergency flares due to the
safety and operational concerns highlighted in our August 3, 2022 letter detailing
stack testing problems.

[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.

[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 new 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.
