(f) As a result of the changes described above, the source has requested that the annual production limit for the extraction plant be increased from 1,686,300 tons per year to 2,251,836 tons per year. Consequently, LDAI has also requested a re-evaluation of the BACT determination for the soybean oil extraction plant to include this increase in production. Biodiesel Production Plant (g) A new methanol/sodium methylate unloading pump will be installed, allowing the methanol/sodium methylate unloading rate to increase. The applicant intends to construct and operate new equipment that will emit air pollutants; therefore, the permit contains new or different permit conditions. In addition, some conditions from previously issued permits/approvals have been corrected, changed, or removed. These corrections, changes, and removals may include Title I changes (e.g., changes that add or modify synthetic minor emission limits). IDEM has reviewed this application and has developed preliminary findings, consisting of a draft permit and several supporting documents, that would allow the applicant to make this change. A copy of the permit application and IDEM’s preliminary findings are available at: Warsaw Community Public Library 315 East Center Street Warsaw, IN 46580 and Northern Regional Office 300 North Michigan Street, Suite 450 South Bend, IN 46601-1253 A copy of the preliminary findings is available on the Internet at: http://www.in.gov/ai/appfiles/idem-caats/. How can you participate in this process? The date that this notice is published in a newspaper marks the beginning of a 30-day public comment period. If the 30th day of the comment period falls on a day when IDEM offices are closed for business, all comments must be postmarked or delivered in person on the next business day that IDEM is open. You may request that IDEM hold a public hearing about this draft permit. If adverse comments concerning the air pollution impact of this draft permit are received, with a request for a public hearing, IDEM will decide whether or not to hold a public hearing. IDEM could also decide to hold a public meeting instead of, or in addition to, a public hearing. If a public hearing or meeting is held, IDEM will make a separate announcement of the date, time, and location of that hearing or meeting. At a hearing, you would have an opportunity to submit written comments and make verbal comments. At a meeting, you would have an opportunity to submit written comments, ask questions, and discuss any air pollution concerns with IDEM staff. Comments and supporting documentation, or a request for a public hearing should be sent in writing to IDEM at the address below. If you comment via e-mail, please include your full U.S. mailing address so that you can be added to IDEM’s mailing list to receive notice of future action related to this permit.

For additional information about air permits and how you can participate, please see IDEM’s Guide for Citizen Participation and Permit Guide on the Internet at: www.idem.in.gov. What will happen after IDEM makes a decision? Following the end of the public comment period, IDEM will issue a Notice of Decision stating whether the permit has been issued or denied. If the permit is issued, it may be different than the draft permit because of comments that were received during the public comment period. If comments are received during the public notice period, the final decision will include a document that summarizes the comments and IDEM’s response to those comments. If you have submitted comments or have asked to be added to the mailing list, you will receive a Notice of the Decision. The notice will provide details on how you may appeal IDEM’s decision, if you disagree with that decision. The final decision will also be available on the Internet at the address indicated above, at the local library indicated above, at the Regional Office indicated above, and the IDEM public file room on the 12th floor of the Indiana Government Center North, 100 N.
