- month period. Applicable Compliance Method : The lb/mmBtu limitation is based on manufacturer’s data (HHV). The hourly emission limitation was develo ped by multiplying the maximum heat input (99 mmBtu/hr) by the NO x emission factor supplied by the manufacturer (0.020 lb/mmBtu) to determine the hourly emissions. The annual NO x emission limitation was developed by multiplying the hourly emission limitation (1.98 lbs/hr) by the maximum annual operating hours (4,500 hrs/yr) and dividing by 2,000 pounds per ton. Therefore, compliance with the annual limitation shall be demonstrated if compliance with the hourly limitation is shown. Compliance with the short
-term emission limitations shall be demonstrated based upon the emission test required in f)(2).
c. Emission Limitation : PM 10 and PM 2.5 shall not exceed 0.008 lb/mmBtu of heat input (HHV), 0.79 lb/hr, and 1.78 ton per rolling, 12
- month period. Applicable Comp liance Method : The lb/mmBtu limitation is based on manufacturer’s data (HHV). The hourly emission limitation was developed by multiplying the maximum heat input (99 mmBtu/hr) by the PM 10/PM 2.5 emission factor supplied by the manufacturer (0.008 lb/mmBtu) to determine the hourly emissions. If required, the permittee shall demonstrate compliance with the lb/mmBtu and hourly emission limitations using Methods 201 or 201A and 202 of 40 CFR Part 51, Ap pendix M. Alternative U.S. EPA
-approved test methods may be used with prior approval from the Ohio EPA. The annual PM 10/PM 2.5 emission limitation was developed by multiplying the hourly emission limitation (0.79 lb/hr) by the maximum annual operating hours (4,500 hrs/yr) and dividing by 2,000 pounds per ton. Th erefore, compliance with the annual limitation shall be demonstrated if compliance with the hourly limitation is shown.Final Permit-to -Install Carroll County Energy LLC Permit Number: P0113762 Facility ID: 0210002025 Effective Date : 11/5/2013

Page 20 of 69 d. Emission Limitation : SO 2 emissions shall not exceed 2.9E
-03 lb/mmBtu of heat input (HHV) and 0.65 ton/yr. Applicable Compliance Method : The lb/mmBtu limitation (HHV) was established based on using natural gas having a maxi mum sulfur content of 1.0 grain per 100 cubic feet according to the following calculation. M ultiply the maximum sulfur content of natural gas (1.0 grain S/100 scf) by the molecular weight of SO 2 (64.07 lb SO 2/lb
- mole) divide by the molecular weight of sulfur (32.06 lb S/lb
- mole) divide by (7,000 grains/lb), divide by (1,000 Btu/scf), and multiply by (10 6 Btu/mmBtu). If required, the permittee shall demonstrate compliance with the lb/mmBtu emission limitation using Methods 1 thru 4 and 6C of 40 CFR Part 60, Appendix A. Alternative U.S. EPA
-approved test methods may be used with prior approval fr om the Ohio EPA. The annual emission limitation was developed by multiplying the lb/mmBtu emission limitation (2.9E
-03 lb/mmBtu) by the maximum heat input (99 mmBtu/hr), multiplied by the maximum operating hours (4,500 hrs/yr) and then dividing by 2,000 pounds per ton. Therefore compliance with the annual limitation shall be demonstrated if compliance with the hourly limitation is shown.
e. Emission Limitation : VOC emissions shall not exceed 0.006 lb/mmBtu of heat input, 0.59 lb/hr, and 1.34 ton per rolling, 12
- month period. Applicable Compliance Method : The lb/mmBtu limitation is based on manufacturer’s data (HHV). The hourly emission limitation was developed by multiplying the maximum heat input (99 mmBtu/hr) by the VOC emission factor supplied by the manufacturer (0.006 lb/mmBtu) to determine the hourly emissions. If required, the permittee shall demonstrate compliance with the lb/mmBtu and hourly emission limitations using Methods 1 through 4 and 18, 25 or 25A, as appropriate, of 40 CFR Part 60, Appendix A. Use of M ethod 18, 25 or 25A is to be selected based on the results of pre-survey stack sampling and U.S. EPA guidance d ocuments. Alternative U.S. EPA
-approved test methods may be used with prior approval from the Ohio EPA. The annual emission limitation was developed by multiplying the hourly emission limitati on (0.59 lb/hr) by the maximum annual operating hours (4,500 hrs/yr) and dividing by 2,000 pounds per ton. Therefore, compliance with the annual limitation shall be demonstrated if compliance with the hourly limitation is maintained.Final Permit-to -Install Carroll County Energy LLC Permit Number: P0113762 Facility ID: 0210002025 Effective Date : 11/5/2013

-04 lb H 2SO 4/mmBtu Multiply the lb H 2SO 4/mmBtu (2.2E
-04 lb/mmBtu) by the maximum heat input (99 mm Btu/hr) to determine the maximum hourly H 2SO 4 emissions (0.02 lb/hr), and multiply by the maximum annual hours of operation (4,500 hrs/yr) divided by 2,000 lbs/ton to determine the annual H 2SO 4 emissions (0.05 ton/yr). If required, the permittee shall demo nstrate compliance with the lb/mmBtu and lb/hr emission limitations using Methods 1 thru 4 and 8 of 40 CFR Part 60, Appendix A. g. Emission Limitation : CO 2e emissions shall not exceed 26,259.76 tons per rolling, 12
- month period. Applicable Compliance Method : This emission limitation was established to reflect the potential to emit for this emissions unit by calculating the sum of the product of the maximum natural gas firing rate (99 mmBtu/hr) multiplied by the AP
-42 emission factor for CO 2 , N 2O, and CH 4from Ta ble 1.4

(11) The Permit to Install application for these emissions units , P001 and P002 , was evaluated based on the actual materials and the design parameters of the emissions unit's(s’) exhaust system, as specified by the permittee. The “Toxic Air Contaminant Statute”, ORC 3704.03(F), was applied to this/these emissions unit(s) for each toxic air contaminant listed in OAC rule 3745
- 114
-01, u sing data from the permit application; and modeling was performed for each toxic air contaminant(s) emitted at over one ton per year using an air dispersion model such as SCREEN3, AERMOD, or ISCST3, or other Ohio EPA approved model. The predicted 1
- hour m aximum ground
- level concentration result(s) from the approved air dispersion model, was compared to the Maximum Acceptable Ground
-Level Concentration (MAGLC), calculated as described in the Ohio EPA guidance document entitled “Review of New Sources of Air Toxic Emissions, Option A”, as follows:
a. the exposure limit, expressed as a time
-weighted average concentration for a conventional 8
- hour workday and a 40
-hour workweek, for each toxic compound(s) emitted fr om the emissions unit(s), (as determined from the raw materials processed and/or coatings or other materials applied) has been documented from one of the following sources and in the following order of preference (TLV was and shall be used, if the chemical is listed): i. threshold limit value (TLV) fr om the American Conference of Governmental Industrial Hygienists (ACGIH) “Threshold Limit Values for Chemical Substances and Physical Agents Biological Exposure Indices”; or ii. STEL (short term exposure limit) or the ceiling val ue fr om the American Conference of Governmental Industrial Hygienists (ACGIH) “Threshold Limit Values for Chemical Substances and Physical Agents BiologicalFinal Permit-to -Install Carroll County Energy LLC Permit Number: P0113762 Facility ID: 0210002025 Effective Date : 11/5/2013

- minute exposu re limit to an equivalent 8
- hour TLV. b. The TLV is divided by ten to adjust the standard fr om the working population to the general public (TLV/10).
c. This standard is/was then adjusted to account for the duration of the exposure or the operating hours of the emissions unit(s), i.e., “X = 24 ” hours per day and “Y = 7 ” days per week, fr

om that of 8 hours per day and 5 days per week. The resulting calculation was (and shall be) used to determine the Maximum Acceptable Ground
- Level Concentration (MAGLC): TLV/10 x 8/X x 5/Y = 4 TLV/XY = MAGLC d. The following summarizes the results of dispersion modeling for the “worst case” toxic contaminant(s): Toxic Contaminant: H 2SO 4 TLV (mg/m3): 0.2 mg/m 3 Maximum Hourly Emission Rate (lbs/hr): 4.1 Predicted 1
- Hour Maximum Ground
- Level Concentration ( μ g/m3): 0.9 MAGLC ( μ g/m3): 4.76 The permittee, has demonstrated that emissions of H 2SO 4 , from emissions unit(s) P001 and P002 , is calculated to be less than eighty percent of the maximum acceptable ground level concentration ( MAGLC); any new raw material or processing agent shall not be applied without evaluating each component toxic air contaminant in accordance with the “Toxic Air Contaminant Statute”, ORC 3704.03(F). (12) Prior to making any physical changes to or changes in the method of operation of the emissions unit(s), that could impact the parameters or values that were used in the predicted 1
- hour maximum ground
- level concentration, the permittee shall re- model the change(s) to demonstrate that the MAGLC has not been exceed ed. Changes that can affect the parameters/values used in determining the 1
- hour maximum ground
- level concentration include, but are not limited to, the following:
a. changes in the composition of the materials used or the use of new materials, that would result in the emission of a new toxic air contaminant with a lower Threshold Limit Value (TLV) than the lowest TLV previously modeled; b. changes in the composition of the materials, or use of new materials, that would result in an increase in emissions of any toxic air contaminant listed in OAC rule 3745
- 114
-01, that was modeled from the initial (or last) application; and
c. physical changes to the emissions unit(s) or its/their exhaust parameters (e.g., increased/ decreased exhaust flow, changes in stack height, changes in stack diameter, etc.).Final Permit-to -Install Carroll County Energy LLC Permit Number: P0113762 Facility ID: 0210002025 Effective Date : 11/5/2013

Page 55 of 69 If the permittee determines that the “Toxic Air Contaminant Statute” will be satisfied for the above changes, the Ohio EPA will not consider the change(s) to be a "modification" under OAC rule 3745
-31
-01 solely due to a no n - restrictive change to a parameter or process operation, where compliance with the “Toxic Air Contaminant Statute”, ORC 3704.03(F), has been documented. If the change(s) meet(s) the definition of a “modification”, the permittee shall apply for and obtain a fi nal PTI prior to the change. The Director may consider any significant departure from the operations of the emissions unit, described in the permit application, as a modification that results in greater emissions than the emissions rate modeled to determine the ground level concentration; and he/she may require the permittee to submit a permit application for the increased emissions. (13) The permittee shall collect, record, and retain the following information for each toxic evaluation conducted to determ ine compliance with the “Toxic Air Contaminant Statute”, ORC 3704.03(F):
a. a description of the parameters/values used in each compliance demonstration and the parameters or values changed for any re-evaluation of the toxic(s) modeled (the composition of materials, new toxic contaminants emitted, change in stack/exhaust parameters, etc.); b. the Maximum Acceptable Ground
-Level Concentration (MAGLC) for each significant toxic contaminant or worst
-case contaminant, calculated in accordance with the “Toxic Air Contaminant Statute”, ORC 3704.03(F);
c. a copy of the computer model run(s), that established the predicted 1
- hour maximum ground
- level concentration that demonstrated the emissions unit(s) to be in compliance with the “Toxic Air Contaminant Statute”, ORC 3704.03(F), initially and for each change that requires re-evaluation of the toxic air contaminant emissions; and d. the documentation of the initial evaluation of compliance with the “Toxic Air Contaminant Statute”, ORC 3704.03(F), and documentation of any determi nation that was conducted to re-evaluate compliance due to a change made to the emissions unit(s) or the materials applied. (14) The permittee shall maintain a record of any change made to a parameter or value used in the dispersion model, used to demonstrate compliance with the “Toxic Air Contaminant Statute”, ORC 3704.03(F), through the predicted 1
