OAQ General Source Data Application GSD-03 Process Flow Diagram {51599}

GSD-03 ­ Process Flow Diagram ­ INSTRUCTIONS Microsoft Word version of GSD-03 Adobe PDF version of GSD-03 The purpose of GSD-03 (State Form 51599) is to provide a checklist for identifying the information to be included on each Process Flow diagram. (You will also need to submit the appropriate Process Information (PI) form for each process.) A GSD-03 form and the associated Process Flow diagram are required for each process included in any air permit application 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. NOTE: IDEM, OAQ has provided an example of a basic process flow diagram on the Air Permit Applications Forms website. This is only an example and has not been drawn to scale. You are not limited to this illustration; add any information you feel is necessary to fully describe the process. 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: Process Flow Diagram Part A provides basic information to understanding the nature of the process. Please use this table as a checklist to indicate that you have included the following items on your process flow diagram (All throughputs should be given in pounds per hour.): 1. Process Description: Briefly describe the process in the space provided and also on the process flow diagram. 2. Process Equipment: Check this box to indicate that you have shown all equipment used in the process on the process flow diagram. You will also need to include the emissions unit identification numbers that will be used throughout the application to refer to this equipment. 3. Raw Material Input: Identify all raw materials used, and state the raw material input at each step of the process in pounds per hour (lbs/hr). 4. Process Throughput: Identify all intermediate and final products, and state the maximum process throughput (maximum capacity) in pounds per hour (lbs/hr) at each step of the process. 5. Additions / Deletions / Modifications: Identify any additional equipment that has been added since the last time the permit was updated. State if any equipment was deleted since the last time the permit was updated. Identify any proposed modifications to the existing process. Use the space provided to briefly explain the impacts of the additional equipment, the reason for removing any equipment, and/or the reason for the proposed modification. (If additional space is needed, please attach a separate sheet with the information and indicate that additional information is attached.) Part B: Process Operation Schedule Part B is intended to indicate the actual hours of operation for the process. NOTE: Indiana Law requires permit emission limits to be based on the potential to emit (PTE) air pollutants as if the process was operating at full capacity 24 hours per day, seven (7) days per week. It is important to provide the actual hours of operation so we can compare the potential to emit with actual estimated emissions. Some sources may opt to take a limit on the potential to emit for the entire source, or individual processes, in order to better reflect the actual operating scenario. 6. Process Operation Schedule: Indicate the actual operation schedule for each process in hours per day (hr/d), days per week (d/wk), and weeks per year (wk/yr). If individual emissions units operate on different schedules, include the actual operation schedule for each emissions unit. If there will be scheduled periods of downtime, please include as much information as is known at the time of application. American LegalNet, Inc. www.FormsWorkflow.com 7. Scheduled Downtime: Use the space provided to include as much information as is known about scheduled periods of downtime for this process. (If additional space is needed, please attach a separate sheet with the information and indicate that additional information is attached.) Part C: Emissions Point Information Part C provides information about each potential outlet of air pollutant emissions to the atmosphere. Please use this table as a checklist to indicate that you have included the following items on your process flow diagram (All throughputs should be given in pounds per hour.): 8. Stack / Vent Information: Each stack or vent is a point along the process where air pollutant emissions may be generated. Identify all the emission points for the process and denote which stack or vent is used to vent the emissions to the atmosphere. If the process is vented inside the building, identify where the fugitive emissions are most likely to escape through building doors and windows. You will also need to include the stack identification, height, diameter, gas discharge temperature, and gas flow rate for each of these emission points on form GSD-04, Stack/Vent Information. 9. Pollutants Emitted: Identify all pollutants released to the atmosphere in pounds per hour (lbs/hr) during normal operation and at each step of the process. 10. Air Pollution Control: Identify all air pollution control equipment and control techniques used at each step of the process. For each method of control, indicate what air pollutants will be abated. For each piece of control equipment, state the control and capture efficiencies and include a unique identification number for the device. Part D: Process Flow Diagram Part D provides a place for a hand drawn process flow diagram. It is optional to use this space to create your process flow diagram, but you must include the diagram with your application. If you choose to submit the process flow diagram in a different format, state "process flow diagram attached" in the space provided, and submit the information with your completed application. IDEM, OAQ has provided an example of a basic process flow diagram on the Air Permit Applications Forms website. ***SUBMISSION OF CONFIDENTIAL RECORDS*** All information submitted to IDEM will be made available to the public unless it is submitted under a claim of confidentiality. Claim of confidentiality must be made at the time the information is submitted to IDEM, and must follow the requirements set out in 326 IAC 17.1-4-1. Failure to follow these requirements exactly will result in your confidential information becoming a public record, a
