SUBJECT:	Summary of Integrated Iron and Steel Point Source Emissions Estimates for Risk and Technology Review
__________________________________________________________________________________________
1.0	INTRODUCTION
This memorandum describes the point source emission estimates used as part of the Residual Risk and Technology Review (RTR) of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Integrated Iron and Steel Manufacturing (II&S) industry (40 CFR, part 63, subpart FFFFF). The primary source of data for the II&S RTR was the responses to an August 2011 information collection request (ICR) sent to the II&S industry that included a questionnaire and a source test request. (EPA, 2018a) The EPA sent out the II&S ICR under the authority of section 114 of the CAA (42 U.S.C. 7414) to acquire the necessary data for the RTR.

      The purpose of this memorandum is to provide an overview of the point source emissions estimates developed from the ICR data obtained from II&S facilities for their emission units as compiled into the II&S Emissions Database. The development of the point source data from the ICR responses are described in detail in a memorandum entitled, "Integrated Iron and Steel Risk and Technology Review: Point Source Data Summary" (EPA, 2019c), that will hereafter be referred to as the "Data Memorandum." Noncategory emissions from sources co-located at II&S facilities are also described in the Data Memorandum. Emission estimates for fugitive emissions from the source category are addressed in the memorandum entitled: "Costs, Emissions and Other Impacts of Control of Fugitive Emissions from the Iron and Steel Industry" (EPA, 2019a).

2.0 	BACKGROUND
In accordance with section 112 of the Clean Air Act (CAA), on May 20, 2003, the U.S. Environmental Protection Agency (EPA) established a NESHAP for the II&S industry (68 FR 27646). The 2003 II&S NESHAP establishes Maximum Achievable Control Technology (MACT) standards for emissions of filterable particulate matter (PM) and opacity as surrogates for hazardous air pollutant (HAP) metals. The rule also establishes standards for the oil content of sinter feed, as a surrogate for volatile organic HAP. In addition, the II&S NESHAP establishes work practice standards for additional control of HAP metals. The regulated emission sources at II&S facilities in the 2003 II&S NESHAP include: blast furnaces (BF); basic oxygen process furnace shops (BOPF); hot metal transfer, desulfurization and skimming units (HMTDS); ladle metallurgy operations; and sinter plant emission sources that included the sinter plant windbox exhaust stream, sinter plant discharge end, and sinter cooler.

installed units. The II&S ICR data used to populate the II&S Emissions Database, as well as the surrogate data and development of other emission estimates, are described in the Data Memorandum. 

4.0	SOURCES OF EMISSIONS DATA
Seventy percent of the point source data in the II&S Emissions Database were from source tests. However, II&S facilities could submit previous test reports in lieu of conducting ICR source testing if the tests were conducted within the previous five years of the II&S ICR and the tests were performed with the required EPA methods, minimum test duration, and/or minimum number of test runs, as specified in the II&S ICR. Additionally, facilities with multiple units were permitted to test only one unit (e.g., BOPF or ladle) to fulfill the II&S ICR test request if there were other similar units on site that exhausted to the same type of control device, processed the same types of materials, were the same size and design, and have similar operating conditions. The test data obtained for similar sources were used as surrogate data in the II&S Emissions Database for the units not tested.  
Units that were completely idle in 2011 were not tested as part of the II&S ICR. For idle units that could not test similar on-site units, an industry average for that unit type was developed from the ICR data to estimate HAP emissions for the idle unit. II&S facilities with BFs that use flame/fume suppression control (with a natural gas-fired flame) were exempted from testing for the II&S ICR because they are unable to perform stack testing for safety reasons due to an explosion hazard. For the exempted BF units, source test data from other II&S BFs were used as surrogate data in the II&S Emissions Database. The surrogate data were either the average emissions from BFs on site or the overall industry average of test data from BFs in the II&S Emissions Database for cases where all BFs at the facility used flame/fume suppression. 
      For some II&S facilities, the ductwork to their BF Stoves prevented testing of their stoves directly. Because the BF Stoves were piped into a boiler that could be tested, these facilities could provide test data from their boilers when burning predominately BF gas, in lieu of testing the BF stoves. Table 3 shows the types of data included in the II&S Emissions Database for each unit type. See the Data Memorandum for details on how the emissions were estimated and the units tested.

[a] ICR production values reported for 2010 for all operating (and modeled) units except one facility (see Footnote f). AK Steel (AKS) claimed the operating levels at their two facilities were confidential business information (CBI) in their ICR responses; therefore, only capacities are shown here. 
b From AIST, 2009.
[c] Slag capacity for the facilities is not known. "Slag in Pits" above reflects slag tonnage sent to slag pits in 2010. At AM-IH-E, slag from blast furnace (BF) #IH7 (1,140,254 tpy) is sent to a granulator so not included as slag pit slag. When operating, the other two BF units (#IH5 and #IH6) were reported in the ICR to generate a total of 228,841 tpy slag for a facility slag total generated of 1,369,095 tpy. Since BF #IH5 and #IH6 were not operating in 2011 and not tested for the ICR (nor included in the risk modeling), their slag is not included in table above, so slag pit slag equals zero. At USS Gary, slag from BF #14, at 508,623 tpy, is sent to a granulator so not included in the slag pit slag (ICR) in table above. The total generated slag at the facility is 1,580,467 tpy. See Footnote d, below, for information about number of slag pits.
[d] Corresponds to working slag pits in 2011. In general, number of slag pits (ICR) equals number of BF (ICR), except for USS-Gary (BF #14) and AM-IH-E (BF #IH7). One BF at each of these facilities produces slag that is sent to a granulator; therefore, there are no slag pits for these BFs. For USS-Gary, this is reflected in the number of slag units, i.e., one less unit than the number of operating BF units. However, for AM-IH-E, during ICR testing in 2011 the other two BFs (#IH5 and #IH6) were not operating nor included in EPA modeling; therefore, no slag pits are indicated in table above for this facility. See Footnote c, above, for information about slag tonnage.
e For purpose of estimated BF bell leaks, three facilities have some BF without bells, as follows: AM Cleveland, BF #6; AM IH-E, BF #IH7, and USS Gary, BFs #14 & #4. Therefore, the number of BFs should be reduced by these units when estimating BF bell leaks for the facilities and, similarly, the iron production reduced. For AM-Cleveland, without BF #C6 (963,952 tpy iron), iron contributing to bell leaks from BF #C5 is 1,295,932 tpy. For AM-IH-E, without #IH7 (3,925,597 tpy iron), iron contributing to bell leaks from BFs #IH5 and #IH6 would be 979,732 tpy if these units were operating. For Gary, without BF #4 (1,108,767 tpy) and BF #14 (2,034,491 tpy), iron contributing to bell leaks from BFs #6 and BF #8 is 1,978,609 tpy.
[f] AM-BH provided 2011 production values that were more representative of normal operations than 2010. 
[g] AM-IH-E was not operating BFs #IH5 and #IH6 during the ICR testing in 2011, so no stack tests were conducted and the EPA did not include these BFs in the risk modelling; therefore, ICR iron production shown in table is for BF #IH7 only. Total iron in 2010 for all three BFs at AM-IH-E was 4,905,329 tpy.
[h] AM-IH-W  BF #IH3 was not operating in 2010 so no annual iron or slag data available; estimated iron and slag from 2011 tph iron production during BF stove testing and hours/yr reported for BF #IH4 in 2010.
[i] USS-Ecorse was not operating BF #A1 during the ICR testing, so no stack tests were conducted and the EPA did not model this BF. Production values for iron and slag also were not available in the ICR. Data above reflects only BFs #B2 and #B4.

5.0	EMISSIONS ESTIMATES

The source test data requested in the II&S ICR included the following air pollutants or parameters: filterable particulate matter (PM filterable), hazardous air pollutant (HAP) metals,[1] dioxin/furans (D/F), carbon disulfide (CS2), carbonyl sulfide (COS), hydrogen chloride (HCl), benzene, toluene, xylene, methane, polycyclic aromatic hydrocarbons (PAHs), carbon monoxide (CO), sulfur dioxide (SO2), oxides of nitrogen (NOX), and hydrogen cyanide (HCN)). All point sources had at least one control device that included fabric filters (baghouses), cartridge filter collectors, PM scrubbers, electrostatic precipitators (ESP), and fume suppressants (natural gas). In most cases, HAP emissions were measured directly using EPA stack test methods. For a few cases, HAP emissions were estimated from other ICR test data using various methodologies as discussed below.

Mercury emissions were speciated into elemental, and divalent and gaseous particulate because of wide differences in toxicity and aerodynamic behavior between the species. The speciation for mercury was done using the total measured mercury and EPA default speciation factors, as follows: elemental gaseous mercury, 80 percent; gaseous divalent mercury and particulate divalent mercury each at 10 percent. The use of these default factors is discussed in more detail in the Data Memorandum. 

      Chromium toxicity also varies by speciation; therefore, chromium was speciated into chromium III and VI. The BOPF (primary and secondary), Blast Furnace, and BF Stoves were required to test separately for chromium VI (hexavalent chromium) and total chromium. For all other II&S emission units, only total chromium emissions were measured.[3] For units where only total chromium data were available, estimates of hexavalent chromium emissions were made using a hexavalent-to-total chromium ratio developed by averaging test data for total chromium and hexavalent chromium from all BOPF in the II&S Emissions Database. Further detail on chromium speciation factors can be found in the Data Memorandum. 

      Emissions of hydrogen cyanide (HCN) from cooling towers used for BF scrubber wastewater at II&S facilities could not be tested directly because these emissions are fugitive and from a very large source (tower). Therefore, wastewater flowrates and HCN water concentration data before and after the cooling tower data were obtained from the ICR to enable a mass balance estimate of HCN emissions. The air emissions of HCN were estimated as the loss in HCN mass in the scrubber wastewater from the inlet to the outlet of the cooling tower. Not all facilities could sample both or any of the sampling points because of equipment configurations. Therefore, HCN emissions were estimated in the II&S Emissions Database from a combination of mass balance and models, or a default industry average developed from the ICR data. Seven facilities either submitted complete data that enabled a mass balance estimate or a combination of measured data and estimating procedures or models. Using the HCN emission estimates from these seven facilities, a default emissions value was developed for the remaining three facilities. One facility does not have a cooling tower. Details of the HCN emissions estimates can be found in the memorandum entitled: "Estimated Hydrogen Cyanide Emissions and Potential Work Practices for Emission Control at Integrated Iron & Steel Facilities." (EPA, 2018b)

For dioxins and furans, emissions of 17 individual dioxin/furan congeners were required to be tested in the II&S ICR because of varying toxicity of the congeners. The 17 dioxin/furan congener values, expressed as mass rates, were entered in the II&S Emissions Database for each facility and unit. 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) and summed to produce a total TEQ value in the II&S Emissions Database. The EPA uses the total TEQ toxicity value to establish MACT, if needed. Details of the TEQ and TEF factors can be found in the Data Memorandum. 

6.0 	POINT SOURCE EMISSIONS DATABASE
      The point source emissions measured or estimated for the II&S Steel facilities, as described above, were compiled into the II&S Emissions Database. This file is attached here as an Excel[TM] file. Selected data summaries are shown in the tables below. See the Data Memorandum for details on how the emissions were estimated and the units tested.
      
      Table 4 shows the total point source HAP emissions for each of the 11 II&S facilities, by unit type. Table 5 shows the 2011 estimated point source HAP emissions by HAP for all the 11 II&S facilities combined. Note only three facilities have sinter plants. Table 6 shows point source HAP emissions for all 11 facilities by unit and by HAP in pounds (lb) per year. Table 7 shows the 2011 estimated annual PM filterable emissions for all 11 facilities.
