Indiana Department of Environmental Management Office of Air Quality Air Permit Application Page 1 of 4 PI-18 Instructions 5/2006 PROCESS INFORMATION: Mineral Processing­ INSTRUCTIONS Microsoft Word version of PI-18 Adobe PDF version of PI-18 The purpose of PI-18 (state form 52559) is to obtain detailed information about mineral processes, including non-metallic minerals and sand and gravel processes. Complete one form for each process (or group of identical processes). PI-18 is a required form for all air permit applications submitted to IDEM, OAQ. For the purposes of this form, the term "source" refers to the plant as a whole and NOT to the individual emissions units. If you do not provide the enough information to adequately describe the process, the application process may be stopped. If you have any questions, contact the Air Permit Reviewer of the Day (PROD) at (317) 233-0178 or 1-800-451-6027 extension 3-0178 (toll free call within Indiana). Part A: Mineral Processing Information Part A specifies the details of the mineral processing equipment including conveyors, screens, and crushers. 1. Type of Process Material: Specify whether the process material is metallic or non-metallic minerals. 2. Equipment / Process Unit: List each equipment or process unit. If there are multiple process units that are identical in nature, capacity, and use, you may use one row to summarize the data for the identical process units. 3. Number of Identical Units: Identical units must be of the same type, capacity, and installation date. If more than one identical unit, specify the number of units in the space provided. 4. Unit ID: Provide the identification number for each unit. The identification numbers listed on this form should correspond to the emissions unit identified on the Plant Layout and Process Flow diagrams. 5. Installation Date: Provide the date on which the process unit was installed. If the exact date is not known, provide the month and year of the installation. If the unit has not yet been installed, provide the anticipated installation date. If the unit has been modified since the original installation, include the most recent modification date. 6. Open / Enclosed: Specify whether each process unit is open to the atmosphere or enclosed in a building. 7. Maximum Capacity: Provide the maximum processing capacity of each process unit in tons per hour (tons/hr). 8. Actual Capacity: Provide the average actual processing capacity of each process unit in tons per hour (tons/hr). Part B: Dryer Details Part B specifies the details of the process dryers. 9. Dryer Type: List each type of dryer used in the process. If there are multiple dryers that are identical in nature, capacity, and use, you may use one row to summarize the data for the identical units. 10. Unit ID: Provide the identification number for each unit. The identification numbers listed on this form should correspond to the emissions unit identified on the Plant Layout and Process Flow diagrams.

Installation Date: Provide the date on which each dryer was installed. If the exact date is not known, provide the month and year of the installation. If the unit has not yet been installed, provide the anticipated installation date. If the unit has been modified since the original installation, include the most recent modification date. 12. Plate Perforation Diameter / Mesh Size: Provide the plate perforation diameter or mesh size of each dryer in inches (in) or millimeters (mm). Specify which units of measure were used. 13. Volume Capacity: Provide the volumetric capacity of each dryer in cubic feet (ft3). 14. Heat Capacity: Provide the heat capacity of each dryer in million British thermal units per hour (MMBtu/hr). 15. Fuel Used: If applicable, specify whether natural gas is used as the only process fuel. If a fuel other than natural gas is used, include the PI-02F form identifying all fuels used for the process. Complete the applicable PI-02 forms for the combustion process. Part C: Storage and Handling of Materials Part C specifies the details pertaining to aggregate storage and handling. 16. Material Size & Specification: List each type of material stored or handled as part of the process. Include the grain size of the material as well as any other pertinent specifications. 17. Type of Storage: Describe how the material is stored for the process. 18. Storage Capacity: Provide the maximum annual storage capacity for each material in metric tons. 19. Unit ID: Provide the identification number for each unit. The identification numbers listed on this form should correspond to the emissions unit identified on the Plant Layout and Process Flow diagrams. 20. Installation Date: Provide the date on which each dryer was installed. If the exact date is not known, provide the month and year of the installation. If the unit has not yet been installed, provide the anticipated installation date. If the unit has been modified since the original installation, include the most recent modification date. 21. Storage Open or Totally Enclosed / Covered: Specify whether each storage area is open to the atmosphere, enclosed in a building or storage unit, or covered in some fashion. Part D: Emission Factors Part D identifies the emission factors used to calculate air emissions from this process. 22. Process Unit: Identify the process and include the identification number for the unit, if applicable. 23. Air Pollutant: For each process identified, list each air pollutant emitted to the atmosphere during normal operation. If there are multiple pollutants for an process, use a new row for each pollutant. 24. Emission Factor: Provide the relevant emission factor including the appropriate units (e.g., lb/units, lbs/ton, lbs/gal, lbs/cf, etc.).

Source of Emission Factor: Provide the source of the emission factors. Common sources include AP-42, stack test data, engineering analysis. The United States Environmental Protection Agency (U.S. EPA) has developed a Clearinghouse for Inventories & Emission Factors containing AP-42 and other emission factors. Appendix A of AP-42 lists several common conversion
