Page 3 of 289 State of Ohio Environmental Protection Agency Division of Air Pollution Control 1. Federally Enforceable Standard Terms and Conditions a) All Standard Terms and Conditions are federally enforceable, with the exception of those listed below which are enforceable under State law only: (1) Standard Term and Condition A. 24., Reporting Re quirements Related to Monitoring and Record Keeping Requirements of State-Only Enforceable Permit Terms and Conditions (2) Standard Term and Condition A. 25., Records Retention Requirements for State -Only Enforceable Permit Terms and Conditions (3) Standard Term and Condition A. 27., Scheduled Maintenance/Malfunction Reporting (4) Standard Term and Condition A. 29., Additional Reporting Requirements Wh en There Are No Deviations of Federally Enforceable Emission Limitations, Operational Restrictions, or Control Device Operating Parameter Limitations (Authority for term: ORC 3704.036(A)) 2 . Monitoring and Related Record Keeping and Reporting Requirements a ) Except as may otherwise be provided in the terms and conditions for a specific emissions unit ( i.e., in section C. Emissions Unit Terms and Conditions of this Title V permit) , the permittee shall maintain records that include the following, where applicable, for any required monitoring under this permit: (1) The date, place (as defined in the permit), and time of sampling or measurements. (2) The date(s) analyses were performed. (3) The company or entity that performed the analyses. (4) The analytical techniques or methods used. (5) The results of such analyses. (6) The operating conditions existing at the ti me of sampling or measurement. (Authority for term: OAC rule 3745- 77-07(A)(3)(b)(i)) b ) Each record of any monitoring data, testing data, and support information required pursuant to this permit shall be retained for a period of five years from the date the record was created. S upport information shall include all calibration and maintenance records and all original strip -chart recordings for continuous monitoring instrumentation, and copies of all reports required by this permit. Such records may be maintained in computerized form. (Authority for term: OAC rule 3745- 77-07(A)(3)(b)(ii)) c) The permittee shall submit required reports in the following manner: (1) All reporting required in accordance with OAC rule 3745 -77 -07(A)(3)(c) for deviations caused by malfunctions shall be submitted in the following manner:Final Title V Permit Permit Number: P0086884 Facility ID: 0320010005 Effective Date : 1/5/2010

Any malfunction, as defined in OAC rule 3745 - 15 -06(B)(1), shall be promptly reported to the Ohio EPA in accordance with OAC rule 3745 - 15 -06. In addition, to fulfill the OAC rule 3745 -77 - 0 7(A)(3)(c) deviation reporting requirements for malfunctions, written reports that identify each malfunction that occurred during each calendar quarter (including each malfunction reported only verbally in accordance with OAC rule 3745 - 15 -06) shall be subm itted (i.e., postmarked) by January 31, April 30, July 31, and October 31 of each year in accordance with Standard Term and Condition A. 2. c)(2) below; and each report shall cover the previous calendar quarter

. An exceedance of the visible emission limitations specified in OAC rule 3745 - 17 -07(A)(1) that is caused by a malfunction is not a violation and does not need to be reported as a deviation if the owner or operator of the affected air contaminant source or air pollution control equipment complies with the requirements of OAC rule 3745- 17 -07(A)(3)(c). In accordance with OAC rule 3745 - 15 -06, a malfunction reportable under OAC rule 3745 - 15 - 06(B) constitutes a violation of an emission limitation (or control requirement) and, therefore, is a deviation of th e federally enforceable permit requirements. Even though verbal notifications and written reports are required for malfunctions pursuant to OAC rule 3745 - 15 -06, the written reports required pursuant to this term must be submitted quarterly to satisfy the p rompt reporting provision of OAC rule 3745-77 -07(A)(3)(c). In identifying each deviation caused by a malfunction, the permittee shall specify the emission limitation(s) (or control requirement(s)) for which the deviation occurred, describe each deviation, and provide the magnitude and duration of each deviation. For a specific malfunction, if this information has been provided in a written report that was submitted in accordance with OAC rule 3745 - 15 -06, the permittee may simply reference that written repo rt to identify the deviation. Nevertheless, all malfunctions, including those reported only verbally in accordance with OAC rule 3745 - 15 -06, must be reported in writing on a quarterly basis. Any scheduled maintenance, as referenced in OAC rule 3745 - 15 -06(A)(1), that results in a deviation from a federally enforceable emission limitation (or control requirement) shall be reported in the same manner as described above for malfunctions. (Authority for term: OAC rule 3745- 77-07(A)(3)(c)) (2) Except as may otherwise be provided in the terms and conditions for a specific emissions unit ( i.e., in section C. Emissions Unit Terms and Conditions of this Title V permit or, in some cases, in section B. Facility-Wide Terms and Conditions of this Title V pe rmit) , all reporting required in accordance with OAC rule 3745 -77 -07(A)(3)(c) for deviations of the emission limitations, operational restrictions, and control device operating parameter limitations shall be submitted in the following manner: Written repo rts of (a) any deviations from federally enforceable emission limitations, operational restrictions, and control device operating parameter limitations, (b) the probable cause of such deviations, and (c) any corrective actions or preventive measures taken, shall be promptly made to the appropriate Ohio EPA District Office or local air agency. Except as provided below, the written reports shall be submitted (i.e., postmarked) by January 31, April 30, July 31, and October 31 of each year; and each report shal l cover the previous calendar quarter. In identifying each deviation, the permittee shall specify the emission limitation(s), operational restriction(s), and/or control device operating parameter limitation(s) for which the deviation occurred, describe ea ch deviation, and provide the estimated magnitude and duration of each deviation.Final Title V Permit Permit Number: P0086884 Facility ID: 0320010005 Effective Date : 1/5/2010

These written deviation reports shall satisfy the requirements of OAC rule 3745 -77 -07(A)(3)(c) pertaining to the submission of monitoring reports every six months and to th e prompt reporting of all deviations. F ull compliance with OAC rule 3745 -77 -07(A)(3)(c) requires reporting of all other deviations of the federally enforceable requirements specified in the permit as required by such rule. If an emissions unit has a deviation reporting requirement for a specific emission limitation, operational restriction, or control device operating parameter limitation that is not on a quarterly basis (e.g., within 30 days following the end of the calendar month, or within 30 or 45 days after the exceedance occurs), that deviation reporting requirement satisfies the reporting requirements specified in this Standard Term and Condition for that specific emission limitation, operational restriction, or control device parameter limitation

. Following the provisions of that non -quarterly deviation reporting requirement will also satisfy (for the deviations so reported) the requirements of OAC rule 3745 -77 -07(A)(3)(c) pertaining to the submission of monitoring reports every six months and to the prompt reporting of all deviations, and additional quarterly deviation reports for that specific emission limitation, operational restriction, or control device parameter limitation are not required pursuant to this Standard Term and Condition. See A.29 below if no deviations occurred during the quarter. (Authority for term: OAC rule 3745- 77-07(A)(3)(c)) (3) All reporting required in accordance with the OAC rule 3745 -77 -07(A)(3)(c) for other deviations of the federally enforceable permit req uirements which are not reported in accordance with Standard Term and Condition A. 2)c)(2) above shall be submitted in the following manner: Unless otherwise specified by rule, written reports that identify deviations of the following federally enforceable requirements contained in this permit; Standard Terms and Conditions: A. 3 , A. 4 , A. 5 , A. 7 .e ) , A. 8 , A.1 3 , A.1 5 , A.1 9 , A. 20 , A.2 1 , and A.2 3 of this Title V permit, as well as any deviations fr

om the requirements in section C. Emissions Unit Terms and Conditions of this Title V permit, and any monitoring, record keeping, and reporting requirements, which are not reported in accordance with Standard Term and Condition A. 2 .c)(2) above shall be submitted (i.e., postmarked) to the appropriate Ohio EPA District Office or local air agency by January 31 and July 31 of each year; and each report shall cover the previous six calendar months. U nless otherwise specified by rule, all other deviations fr om federally enforceable requirements identified in this permit shall be submitted annually as part of the annual compliance certification, including deviations of federally enforceable requirements not specifically addressed by permit or rule for the insignificant activities or emissions levels (IEU) identified in section B

. Facility-Wide Terms and Conditions of this Title V permit. Annual reporting of deviations is deemed adequate to meet the deviation reporting requirements for IEUs unless otherwise specified by permit or rule. In identifying each deviation, the permittee shall specify the federally enforceable requirement for which the deviation occurred, describe each deviation, and provide the magnitude and duration of each deviation. These semi -annual and annual written reports shall satisfy the reporting requiremen ts of OAC rule 3745 -77 -07(A)(3)(c) for any deviations fr om the federally enforceable requirements contained in this permit that are not reported in accordance with Standard Term and Condition A. 2 .c)(2) above.Final Title V Permit Permit Number: P0086884 Facility ID: 0320010005 Effective Date : 1/5/2010

If no such deviations occurred during a six- mo nth period, the permittee shall submit a semi annual report which states that no such deviations occurred during that period. (Authority for term: OAC rules 3745- 77-07(A)(3)(c)(i) and (ii) and OAC rule 3745- 77- 07(A)(13)(b)) (4) Each written report shall be signed by a responsible official certifying that, "based on information and belief formed after reasonable inquiry, the statements and information in the report (including any written malfunction reports required by OAC rule 3745 - 15 -06 that are referenced in the deviation reports) are true, accurate, and complete." (Authority for term: OAC rule 3745- 77-07(A)(3)(c)(iv)) (5) Reports of any required monitoring and/or record keeping information shall be submitted to Ohio EPA DAPC, Northwest District Office

. (Authority for term: OAC rule 3745- 77-07(A)(3)(c)) 3 . Scheduled Maintenance Any scheduled maintenance of air pollution control equipment shall be performed in accordance with paragraph (A) of OAC rule 3745 - 15 -06. Except as provided in OAC rule 3745 - 15 -06(A)(3), any scheduled maintenance necessitating the shutdown or bypassing of any air pollution control system(s) shall be accompanied by the shutdown of the emissions unit(s) that is (are) served by such control system(s). Any scheduled maintena nce, as defined in OAC rule 3745 - 15 -06(A)(1), that results in a deviation from a federally enforceable emission limitation (or control requirement) shall be reported in the same manner as described for malfunctions in Standard Term and Condition A. 2 .c)(1) above. (Authority for term: OAC rule 3745- 77-07(A)(3)(c)) 4. Risk Management Plans If applicable, the permittee shall develop and register a risk management plan pursuant to section 112(r) of the Clean Air Act, as amended, 42 U.S.C. § 7401 et seq. ("Act"); and, pursuant to 40 C.F.R. 68.215(a), the permittee shall submit either of the following: a ) a compliance plan for meeting the requirements of 40 C.F.R.

However, that rule revision has not yet been submitted to the U.S. EPA as a revision to Ohio's State Implementation Plan (SIP). Therefore, until the SIP revision occurs and the U.S. EPA approves the revisions to OAC rule 3745 -21 -08, the requirement to satisfy the "best available control techniques and operating practices" still exists as part of the federally-approved SIP for Ohio. e. The emission limitation specified by this rule is less stringent than the emission limitation established pursuant to OAC rule 3745 -31 -05(A)(3). f. On February 18 , 200 8 , OAC rule 3745 -21 -0 7 was revised in its entirety ; therefore, the 21 -07 rule that was in effect prior to this date i s no longer part of the State regulations. On April 4, 2008 , the rule revision was submitted to the U.S. EPA as a revision to Ohio = s State Implementation Plan (SIP); however, until the U.S. EPA approves the revision to OAC rule 3745 -21 -0 7 , the requirement to comply with the previous 21 -07 rule provisions still exists as part of the federallyap proved SIP for Ohio. The following terms and conditions shall become void after U.S. EPA approves the rule revision: [c)(2) , d)(2) , e)( 1 )f. ] The emission limitations and control requirements from the amended 21 -07 rule, and the asso ciated operational restrictions and the monitoring, record keeping, and reporting requirements contained in this permit , shall become federally enforceable on the date the U.S. EPA approves the revised OAC rule 3745 -21 - 07 as a revision to the Ohio State Implementation Plan.

Based on the "Prevention of Significant Deterioration" (PSD) analysis conducted to ensure the application of "Best Avail able Control Technology" (BACT), it has been determined that no control technologies for CO were cost effective. b. The “ Best Available Technology” (BAT) requirements under OAC rule 3745 -31 - 05(A)(3) do not apply to the nitrogen oxides (NOx) and sulfur dioxide (SO2) emissions from this air contaminant source since the uncontrolled potential to emit for each pollutant is less than ten tons per year. The potential to emit for NOx emissions for this emissions unit is 5.39 tpy; determined by multiplying the maximum hourly emission rate of 1.23 lbs/hr (as determined by stack testing) by the maximum operating schedule of 8760 hours per year. The potential to emit for SO2 emissions for this emissions unit is 0.88 tpy; determined by multiplying the maximum hourly emissi on rate of 0.20 lbs/hr (as determined by stack testing) by the maximum operating schedule of 8760 hours per year. c. All particulate matter emissions are PM10. d. The design of the emissions unit and the technology associated with the current operating practices satisfy the "best available control techniques and operating practices" required pursuant to OAC rule 3745 -21 -08(B).

All PE is assumed to be i n the form of particulate matter less than 10 microns in size (PM10). b. The emission limitation specified by this rule is less stringent than the emission limitation established p ursuant to OAC rule 3745 -31 -05(A)(3). c. The permittee has satisfied the "latest available control techniques and operating practices" required pursuant to OAC rule 3745 -21 -08(B) by committing to comply with the best available technology requirements establis hed pursuant to OAC rule 3745 -31 -05(A)(3) in this Permit to Install. On November 5, 2002, OAC rule 3745 -21 -08 was revised to delete paragraph (B); therefore, paragraph (B) is no longer part of the State regulations. However, that rule revision has not yet been submitted to the U.S. EPA as a revision to Ohio's State Implementation Plan (SIP). Therefore, until the SIP revision occurs and the U.S. EPA approves the revisions to OAC rule 3745 -21 -08, the requirement to satisfy the "best available control techniq ues and operating practices" still exists as part of the federally-approved SIP for Ohio. d. On February 18, 2008, OAC rule 3745 -21 -07 was revised in its entirety; therefore, the 21 -07 rule that was in effect prior to this date is no longer part of the State regulations. O n April 4, 2008, the rule revision was submitted to the U.S. EPA as a revision to Ohio’s State Implementation Plan (SIP); however, until the U.S. EPA approves the revision to OAC rule 3745 -21 -07, the requirement to comply with the previous 2 1 -07 provisions still exists as part of the federallyapproved SIP for Ohio. c) Operational Restrictions (1) The use of any photochemically reactive material in this emissions unit, as defined in OAC rule 3745-21 -01, is prohibited.

This range or limit on the pressure drop across the baghouse is effective for the duration of this permit, unless revisions are requested by the pe rmittee and approved in writing by the appropriate Ohio EPA District Office or local air agency. The permittee may request revisions to the permitted limit or range for the pressure drop based upon information obtained during future testing that demonstrate compliance with the allowable particulate emission rate for the controlled emissions unit(s). I n addition, approved revisions to the range or limit will not constitute a relaxation of the monitoring requirements of this permit and may be incorporated i nto this permit by means of a minor permit modification [Authority for term: OAC rule 3745-77 -07(C)(1) and PTI 03 - 10931] (3) The permittee shall maintain the following daily records for this emissions unit: a. the company identification for each product group m anufactured; b. the numbers of hours of production for each product group manufactured; c. the calculated PE factor (lbs PE/hour of production), based upon the emission factor curve*, for each product group manufactured; and d. the total PE rate (lbs/day), for al l the product groups manufactured [summation of (c x b) for all product groups]. * The permittee calculates the hourly PE by employing a pac factor. The pack factor is the design density of each product produced multiplied by the design thickness of the same product. This resultant value is used to figure out the PE (lbs/hr) from the emission factor curve. The emission factor curve is a statistical polynomial and was derived fr om multiple stack tests on this emissions unit. The hourly PE calculated from th e polynomial is then multiplied by the number of hours of production of the product for which the pack factor was calculated. [Authority for term: OAC rule 3745-77 -07(C)(1) and PTI 03 - 10931] (4) The permittee shall calculate and maintain daily records of the particulate emissions and the rolling 365 -day emissions of particulates , in tons, for emissions units P047, P048, P049, P048, P049, P050, P051, P052, P054 and P055, combined.

If no deviations/excursions occurred during a calendar quarter, the report shall so state that no deviations occurred during the reporting period

. The quarterly deviation reports shall be submitted in accordance with the reporting requirements of the Standard Terms and Conditions of this permit. [Authority for term: OAC rule 3745 - 15 -03(B)(1)(a), OAC rule 3745 - 15 -03(C) and OAC rule 3745 -77 -07(C)(1)] (2) The permittee shall submit quarterly deviation (excursion) reports that identify all excee dances of the rolling, 365 -day PE limitation of 68.8 tons (for emissions units P047, P048, P049, P050, P051, P052, P054 and P055, combined). These deviation reports shall be submitted in accordance with the Standard Terms and Conditions of this permit. [Au thority for term: OAC rule 3745-77 -07(C)(1) and PTI 03 - 10931] f) Testing Requirements (1) Compliance with the emission limitations in b)(1) of the terms and conditions of this permit shall be determined in accordance with the following methods: a. Emission Limitation: PE shall not exceed 66.80 tons per rolling 365 -day period (for emissions units P047, P048, P049, P050, P051, P052, P054 and P055, combined) Applicable Compliance Method: Compliance with the rolling 365 -day PE limitation shall be demonstrated by the re cord keeping requirements specified in d)(2) and d)(3) of this permit.Final Title V Permit Permit Number: P0086884 Facility ID: 0320010005 Effective Date : 1/5/2010

b. Emission Limitations: PE shall not exceed 0.10 lb/hr and 0.44 tpy. Applicable Compliance Method: The hourly allowable P E limitation was established by multiplying an outlet grain loading of 0.02 gr/scf by the maximum flow rate of the silos dust collector (565 acfm) and by 60, and then dividing by 7000. If required, the permittee shall demonstrate compliance with the hourl y PE limitation shall be demonstrated by testing in accordance with Methods 1 - 5 of 40 CFR, Part 60, Appendix A. The tons/yr PE limitation was developed by multiplying the lbs/hr PE limitation by the maximum operating schedule of 8760 hours/yr, and then d ividing by 2000 lbs/ton. Therefore, provided compliance is shown with the hourly limitation, compliance shall also be shown with the annual limitation. [Authority for term: OAC rule 3745-77 -07(C)(1) and PTI 03 - 10931] c. Emission Limitation: Visible PE shall not exceed 0% opacity, as a 6 - minute average. Applicable Compliance Method: If required, the permittee shall demonstrate compliance in accordance with Method 9 of 40 CFR, Part 60, Appendix A.
