1 SWCAA Emission Inventory Instructions Why is an emission inventory required? Most of the emission inventory reporting requirements originated in Title 0 of the Code of Federal Regulations (0 CFR) Part and were intended for the very largest air pollution sources. These rules require that state and local agencies collect data from air pollution sources and submit the data to the National Emission Inventory (NEI). The information in the NEI database is used by EPA and by states for air quality modeling, tracking progress in meeting requirements under the Federal Clean Air Act, setting policy, and answering questions from the public. EPA recently passed the Air Emissions Reporting Rule (AERR), which requires that state and local agencies collect additional information about the air pollution sources in their jurisdictions. There are also other emission inventory reporting requirements under federal, state, and local rules and regulations. In order to comply with EPA's requirements to report emissions from sources within the ozone maintenance plan area, Southwest Clean Air Agency (SWCAA) also collects information from smaller sources that emit pollutants affecting ground level ozone. Who has to be inventoried? SWCAA collects emission information from a variety of air pollution sources in order to prepare an emission inventory of the sources within the jurisdiction. SWCAA is required by EPA under 0 CFR Part Subpart A (0 CFR. et seq) to collect and submit emission inventory data for the following sources for inclusion in the national emission inventory: Any "large" source that has the potential to emit any of the following pollutants above the indicated thresholds is required to submit an emission inventory: o 00 tons/yr or more of nitrogen oxides (NO x ), sulfur dioxide (SO ), volatile organic compounds (VOC), ammonia (NH ), particulate matter (PM) with an aerodynamic diameter of ten microns or less (PM 0 ), or PM with an aerodynamic diameter of. microns or less (PM. ); o tons/yr or more of lead; o 0 tons/yr of more of any individual hazardous air pollutant (HAP); or o tons/yr or more of any combination of HAPs. In addition, any source required to obtain a Title V permit, regardless of emissions, is required under SWCAA 00-0() to submit emission inventory information. What information is reported to EPA? All of the information submitted for the current emission year is submitted by SWCAA, after review, to EPA. This information is often used by EPA, WA Department of Ecology, SWCAA, and other agencies, companies, and individuals for planning, permitting, and computer modeling. The information is compiled into both state and federal inventory databases and is generally publically accessible through direct request for information or through the internet.

All sources in SWCAA jurisdiction are in UTM Zone 0. 0 Emissions is where you can enter a facilitywide summary of emissions from this year. Certification of Data Accuracy. Once you have completed filling out all the forms, sign, print your name and title, and enter the date you completed the forms in this section. Page of 8 INSTRUCTIONS

3 Form A Release Point Information This form is provided for your review and identifies the stacks and fugitive release points at your facility. Any emission through a defined opening is considered a stack. Fugitive release points are points where emissions occur that cannot reasonably be emitted through a stack (e.g, storage piles, evaporative sources). Due to minimum data requirements, if SWCAA does not have enough detailed information on a stack, EPA requires us to classify the release point as a fugitive source. Please make note if there are any errors and we will update the information Release Point is a generic identifier for the stack or emission point. Note that this number may differ from the identification number in your permit. Release Point Description is a short description of the stack or fugitive release point. Release Point Type is one of three listings: Stack Release, Fugitive Release, or Fugitive Release with Missing Data. In order to be considered a stack in the database, the release point must include a stack height, stack diameter, and stack flow rate, at a minimum. If some, but not all, of the minimum required data is provided, SWCAA will consider the release point to be a Fugitive Release with Missing Data. Stack Height applies only if the release point is a stack. Enter the stack height in feet or inches measured from ground level to the exhaust point of the stack. Do not enter anything in the stack height, stack diameter, or stack flow boxes if this is a fugitive release point. Stack Diameter applies only if the release point is a stack. Enter the stack diameter in feet or inches. If the stack is rectangular, use the following equation to calculate a circular diameter equivalent: L W D =., where L is length (ft), W is width (ft), and D is circular diameter equivalent (ft). Stack Flow Rate applies only if the release point is a stack. Enter the flow in actual cubic feet per minute (acfm). If you have flow in standard cubic feet per minute (scfm), you will need to convert the flow to acfm. Stack O is the oxygen content of the exhaust stream of the stack given in percent. This information is often obtained during a stack test. If the stack only vents under ambient conditions, such as a building exhaust, enter 0.9%. Stack H O is the water content of the exhaust stream of the stack given in percent. This information is often obtained during a stack test. Release Point Temp is the temperature of the stack given in F. If the stack is at ambient temperature, enter 8 F. Fugitive Release Point Height is the height of the fugitive emission; do not enter anything in this box if there is a stack. Enter the height that the fugitive emissions are release to the ambient air. Release Point Latitude and Longitude is the latitude and longitude of the release point. If you do not have the specific location of the unit, you can enter the facility's latitude and longitude. Page of 8 INSTRUCTIONS

4 Form B Emission Unit Information This form is provided for your review of the emission units or activities at your facility. Emission Unit is a generic identifier for the emission unit or activity. Note that this number may differ from the identification number in your permit. Emission Unit Description is a short description of the emission unit or activity. EPA Emission Unit Classification is an EPA-assigned code and short description of the mission unit or activity. If the description is not accurate, please make note and SWCAA will update the code. Maximum Design Capacity: If the stack or emission point burn gaseous, liquid, or solid fuels, this is the maximum design capacity of the unit. Typically the units are million British thermal units per hour (MMBTU/HR) or horsepower (HP). Status is Operating, Temporarily Shut Down, or Permanently Shut Down. If the emission unit operated at any time during the year, then it is considered to be Operating. A Temporarily Shut Down unit is one that has no emissions for the reporting year, but may have emissions in the future. A permanently Shut Down emission unit is one that did not operate at all during the reporting year and will no longer operate at any time in the future. Emission Unit Comment is a place for either SWCAA or you to enter a comment about the emission unit. Page of 8 INSTRUCTIONS

5 Form C Emission Process Data Forms C and C describe the emission process associated with each emission unit or activity. Typically a separate process is listed if there is a different emission calculation method or emission factor used. For example, if a boiler can burn both natural gas and fuel oil, it would have two processes, one for each fuel since the fuel usage and emissions would be calculated and reported separately. A process could be a different activity, a different fuel, or a different operating mode. Specific information regarding t heoperating schedule of the process are requested. Emission Unit & Process is a generic identifier for the emission unit or activity and for the emission process. Process Description is a short description of the process. Operation by Season is the percent of the year that the process operated for each calendar quarter. It is typically used in air quality modeling to estimate seasonal impacts. The total of the four numbers should equal 00%. If a unit has no easily discernable seasonality for its operation, enter in each quarter. Typical Operational Schedule: Enter the hours per day, days per week, and weeks per year that each process typically could operate. This is usually /7/, but if the process is operated on a different schedule, for example during only one shift, then this is where that information is entered. Actual Operating Hours is the actual hours that the process operated during the year. This number could be less than the typical operational schedule would indicate. If the information is not readily available, it is acceptable to write in 870 (or 878 on a leap year). Process Comment is a place for either SWCAA or you to enter a comment about the process. Page of 8 INSTRUCTIONS

6 Form C Emission Process Data This form includes the same processes identified in Form C, but requests information regarding the production or operating rates and fuel data. Source Classification: Each process should have an associated Source Classification Code (SCC) A listing of the codes can be obtained from the EPA website at For example, SCC code is for a 0-00 MMBtu/hr natural gas boiler and the units are in million cubic feet (MMcf) of gas burned. A single emission unit may have two or more SCC codes if it uses more than one type of raw material or burns more than one type of fuel. In this case separate SCCs should be included as separate processes. Annual Production/Rate is a value representing a production quantity, consumption quantity, usage quantity, or other quantity related to the emissions of air pollution. Generally the units should be what is used in the emission calculations, but may also be in units that are more representative of the operation of the process. Maximum Hourly Production/Rate is similar to the previous item, but is on an hourly basis. Generally this is a fixed value that does not change from year to year (e.g. boiler maximum firing rate), but may vary with production. In this case, it is acceptable to write in the annual rate divided by the total hours of operation. Fuel Information is required for those process that burn gaseous, liquid, or solid fuels. Depending upon the type of fuel, the types of information varies: Gaseous, Liquid, and Solid Fuels. Fuel heat content in BTU/SCF, BTU/GAL, or BTU/LB is required. This value can represent the average fuel value for the year or a default value. Default values are 00 BTU/SCF for natural gas, 7000 BTU/GAL for # fuel oil or biodiesel, and 000 BTU/LB for coal. Liquid and Solid Fuels. Sulfur content in either percent or ppm is required for liquid and solid fuels. The default value for # fuel oil is 0.00% ( ppm) for # fuel oil; there is no default value for coal, so use the best available information for the coal being burned. Ash content is also required for solid fuels, and with the exception of # fuel oil, also required for liquid fuels. SWCAA generally assumes negligible ash content for # fuel oil, but based on your specific fuel analysis, he ash content may be significant, especially for other liquid fuel such as used oil, PS00, or biodiesel.

7 Form D Criteria Pollutant Emissions This form requests criteria pollutant information for each of the separate processes. Estimation Code (EC): For each emission process and each pollutant, provide the estimation code (EC). This is method used to determine the emission factor. The most common estimation codes are: Code and Description Code and Description Continuous Emission Monitoring System (CEMS) 8 EPA Emission Factor Engineering Judgment 9 SWCAA Emission Factor Material Balance 0 Site-Specific Emission Factor Stack Test/Source Test Vendor Emission Factor EPA Speciation Profile Trade Group Emission Factor SWCAA Speciation Profile Other Emission Factor 7 Manufacturer Specification If you have questions about these codes, please call SWCAA. Tons per Year (TPY): For each process and each pollutant, enter the amount of the pollutant emitted in TPY. Data should be enter to at least three digits to the right of the decimal (e.g.., 0., 0.00), but if there are quantifiable emissions less than 0.00 tpy, enter data with at least one non-zero value at the rightmost digit (e.g., or 0 ). Do not enter a zero, unless the process is operational, but was not operated during the year (i.e. there was a potential for emissions but no actual emissions occurred). If the unit is not capable of emitting a pollutant, either leave blank, write "N/A", or enter a dash do not enter zero. For example, a baghouse controlling on a grain terminal would not be expected to emit nitrogen oxides (NO x ) so the NO x column could be left blank. However, a baghouse on a boiler would emit NO x, so a value would need to be entered in the column. Page 7 of 8 INSTRUCTIONS

8 Form E Toxic Pollutant Emissions This form requests toxic air pollutant (TAP) emissions information for each of the separate processes. Chemical Abstract Service (CAS) #: For each emission process, a CAS number should already be entered for the toxic air pollutant (TAP) emitted. If the process emits a TAP that is not listed, enter the appropriate information elsewhere on the form or on an additional sheet. A list of pollutants can be found at Note that while every effort has been made to be sure to include all the regulated pollutants in the list, there may be some that were not included. If you are unsure, contact SWCAA. Name/Classification: The name of the pollutant should be listed. Please note, however, that the name listed here may be different than the name on an MSDS or other identifier. Because there are many synonyms for chemicals, use the CAS number as the primary identifier. Hazardous Air Pollutant (HAP) is shown either as "Yes" for those pollutants listed as HAPs or "No" for pollutants listed only as toxic air pollutants (TAPs). This should already be listed for each of the pollutants. Estimation Code (EC): For each emission process and each pollutant, provide the estimation code (EC) it is the same type of code as on Form D, but may be different for the specific pollutant being reported. The most common estimation codes are: Code and Description Code and Description Continuous Emission Monitoring System 8 USEPA Emission Factor Engineering Judgment 9 S/L/T Emission Factor Material Balance 0 Site-Specific Emission Factor Stack Test Vendor Emission Factor USEPA Speciation Profile Trade Group Emission Factor S/L/T Speciation Profile Other Emission Factor 7 Manufacturer Specification Emissions: For each emission process and each pollutant, enter the amount of the pollutant emitted in pounds per year (lb/yr). Note that these are different units from the reporting requirements for criteria pollutants. Additional Information When submitting the forms to SWCAA, it is recommended that the facility include any calculations you have made and include a description of any assumptions made when determining your emissions. SWCAA staff can then understand how the emissions were calculated. If you have any questions about how to fill out these emission forms, or how emission information should be determined, please contact your facility s SWCAA representative at (0) Page 8 of 8 INSTRUCTIONS
