6 OVERVIEW  
7                          
8 This Combustion Source Emission Factor (EF) Search Tool is provided for use with the AQ104B Toxics Reporting form and the Air Toxics Emissions Inventory (ATEI) reporting forms, specifically for Worksheets 2 & 3 (color-coded salmon orange). Use of this tool is optional, and operators should determine if the compiled EFs presented here best capture their facility operations, or if other equipment-specific or site-specific EFs are available. Operators who do elect to use this tool, should include all of the provided emission factors for the equipment and not choose selectively.  
9                          
10 These emission factors are assembled from the resources in the Reference section below and have been approved by the Cleaner Air Oregon (CAO) program as acceptable for use in a CAO emissions inventory review. In the absence of facility-specific source tests or manufacturer test data, which may demonstrate different air toxics emissions, these EFs were selected to cover a broad range of possible air toxic contaminants resulting from common fossil fuel combustion activities, and produce conservative emissions estimates. To use the tool, simply copy/paste the complete set of emission factors for the sought equipment type directly into the AQ104B Toxics or ATEI Reporting Form.  
11                          
12 All emission factors listed in this Tool are for uncontrolled* equipment. In other words, no pollution control efficiency is included in the factor. If one or more control devices are present on an emitting unit, that should be clearly captured in the reporting ATEI form Worksheets 2 & 3 to ensure that emissions reductions are appropriately captured. Follow the instructions presented below and in the reporting form.  
13                          
14 If the the units of measure presented in this form do not match those of the facility, or of the operating permit, it may be neceessary to convert units. This step should be performed before the information is pasted into the ATEI reporting form.  
15                          
16 * For Natural Gas and Diesel fired equipment, the default emission factor for Ammonia is based on emission units with Selective Noncatalytic Reduction (SNCR) equipment. Refer to the original chapters in AP-42 to substitute the Ammonia emission factor for units with Selective Catalytic Reduction (SCR) equipment.

24 INSTRUCTIONS  
25                          
26 1) Enter the emission units, control devices and activity on Worksheet 2 of the AQ104B Toxics Reporting or Air Toxics Emissions Inventory reporting form, "2.Emission Units & Activities". Below in an example of a facility with two emission units, an uncontrolled natural gas boiler, and a diesel engine with a catalytic converter control.  
27                          
28
                       
29                          
30 2) Locate the equipment in the Combustion EF Search Tool, and confirm that the equipment type and size are appropriately covered by the available emission factors (also located in the Reference table, below).  
31                          
32 Copy the data for your combustion unit (just the data, not the headers) and paste it into the Reporting form, Worksheet 3 "3.Pollutant Emission-EF" under the correct column headings in the black bar (the form is locked to prevent entering data into the example rows in red text). Repeat this step for each emission unit listed on the reporting form, Worksheet 2.  
33                          
34 a) Select the set of emission factors for the piece of equipment. Copy all the data but omit the headers. In this case, the boiler is 26 MMBtu/hr so the 10-100MMBtu/hr Emission Factors were chosen.  
35
                       
36                          
37                          
38 b) Paste the data onto Worksheet 3 "3. Pollutant Emission-EF" of your 2020 AT EI form. Paste to the first open cell in the CAS column, below the black header bar.  
39
                       
40                          
41                          
42 4) On your AQ104B Toxics Reporting form or AT EI form, copy the Emission Unit ID from Worksheet 2 and paste to each row for that unit on Worksheet 3. As this step is repeated, the warnings in Column I will be replaced with the emissions calculations.  
43
                       
44                          
45 5) Repeat steps 3 and 4 for each emission unit listed on Worksheet 2 (refer to Step 1 example, above).  
46
                       
47                          
48 6) In Worksheet 3 of the reporting form, update the control efficiencies for the control device and note that the resulting emission estimates update accordingly. This information may come from manufacturer specifications. In this example, the catalytic oxidizer removes some organics, but not the metals.

1 Natural Gas External Combustion (Boiler, Oven, Dryer, Heater, Afterburner, Furnace)
2 Emission factors for natural gas-fired external combustion equipment are divided into three sets based on the heat capacity rating of the equipment (<10 MMBtu/hr, 10-100 MMBtu/hr and >100 MMBtu/hr). The emission factors presented here are a combination of EPA's AP-42 section 1.4 for metals, and California's South Coast Air Quality Monitoring District AB2588 for organic compounds, and were selected to be comprehensive and conservative when used in a risk assessment. Criteria pollutants are not included in this data set, as they are typically mandated in permit. See CAO Combustion FAQ for more information about inclusion of Benzo[a]pyrene in this compilation.
4 Ammonia (highlighted yellow): the listed 18 lb/MMSCF value corresponds to equipment with SNCR control. For equipment with SCR, substitute the listed value with 9.1 lb/MMSCF, and for equipment without SNCR or SCR, substitute listed value with 3.2 lb/MMSCF. Update Note accordingly.

1 Natural Gas Internal Combustion Engines (Stationary and Portable)
2 Most natural gas-fired reciprocating engines are used in the natural gas industry at pipeline compressor and storage stations and at gas processing plants. Emission factors for natural gas-fired reciprocating engines are separated into three design classes: 2-cycle (stroke) lean-burn, 4-stroke lean-burn, and 4-stroke rich-burn. The emission factors presented here are a combination of EPA's AP-42 section 3.2 and California's South Coast Air Quality Monitoring District AB2588, and were converted from MMBtu to MMSCF. Criteria pollutants are not included in this data set, as they are typically mandated in permit. PAHs are listed individually.
4 Ammonia (highlighted yellow): the listed 18 lb/MMSCF value corresponds to equipment with Selective Non-catalytic Reduction (SNCR). For equipment with Selective Catalytic Reduction (SCR), substitute the listed value with 9.1 lb/MMSCF, and for equipment without SNCR or SCR, substitute listed value with 3.2 lb/MMSCF. Update Note accordingly.
6 Relevant units of measure: MMBtu = Million British Thermal Units, MMSCF = Million Standard Cubic Feet

1 Diesel Internal Combustion Engines (stationary and portable)
2 In order to meet regulatory standards, internal combustion diesel engines were introduced according to a tiered structure where newer engines ahdere to stricter emissions standard than older ones. Emission factors presented here are divided by Tier 0 and 1 engines, and Tiers 2,3, and 4 engines. The emission factors are a combination of recent source test data, and those found in California's South Coast Air Quality Monitoring District AB2588 table B-2 for Internal diesel combustion engines. All engines smaller than 750kW, regardless of age or tier, should use the first emission factor set. More information is available in the References table in the Instructions tab, or on the Cleaner Air Oregon website.
4 Ammonia (highlighted yellow): the listed 2.9 lb/M gal value corresponds to equipment with Selective Non-catalytic Reduction (SNCR). For equipment with Selective Catalytic Reduction (SCR), substitute the listed value with 1.4 lb/M gal, and for equipment without SNCR or SCR, substitute listed value with 0.8 lb/M gal. Update Note accordingly.
6 Relevant units of measure: M gal = 1,000 gallons
8 Pre-2006 Tier 0 and Tier 1 Diesel Internal Combustion Engines, all engines less than 750kW

1 LPG, Butane, Propane Internal Combustion Engines (Stationary and Portable)
2 Liquefied petroleum gas (LPG or LP-gas) consists of propane, propylene, butane and butylenes. Most LPG-fired reciprocating engines are used in the gas industry at pipeline compressor and storage stations and at gas processing plants. Emission factors are separated into three design classes: 2-cycle (stroke) lean-burn, 4-stroke lean-burn, and 4-stroke rich-burn.
