The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

The deviation reports shall be submitted in accordance with the requirements specified in Part I - General Term and Condition A.1.c. 4.

V. Testing Requirements

Compliance with the emission limitations in section A.I.1 of these terms and conditions shall be determined in accordance with the following methods: 1.

Emission Limitation: 20% opacity as a 6-minute average for stack emissions Applicable Compliance Method: If required, compliance shall be demonstrated based upon the procedures required in 40 CFR Part 60, Appendix A, Method 9 and the methods and procedures specified in OAC rule 3745-17-03(B)(1). 1.a

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions.

Johns Manville International, Inc. / Plant #07 - Wtvl 04-48-00-0013

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

The deviation reports shall be submitted in accordance with the requirements specified in Part I - General Term and Condition A.1.c. 4.

V. Testing Requirements

Compliance with the emission limitations in section A.I.1 of these terms and conditions shall be determined in accordance with the following methods: 1.

Emission Limitation: 20% opacity as a 6-minute average for stack emissions Applicable Compliance Method: If required, compliance shall be demonstrated based upon the procedures required in 40 CFR Part 60, Appendix A, Method 9 and the methods and procedures specified in OAC rule 3745-17-03(B)(1). 1.a

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

The deviation reports shall be submitted in accordance with the requirements specified in Part I - General Term and Condition A.1.c. 4.

V. Testing Requirements

Compliance with the emission limitations in section A.I.1 of these terms and conditions shall be determined in accordance with the following methods: 1.

Emission Limitation: 20% opacity as a 6-minute average for stack emissions Applicable Compliance Method: If required, compliance shall be demonstrated based upon the procedures required in 40 CFR Part 60, Appendix A, Method 9 and the methods and procedures specified in OAC rule 3745-17-03(B)(1). 1.a

Johns Manville International, Inc. / Plant #07 - Wtvl 04-48-00-0013

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

III.Monitoring and/or Record Keeping Requirements (continued)

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

The deviation reports shall be submitted in accordance with the requirements specified in Part I - General Term and Condition A.1.c. 4.

V. Testing Requirements

Compliance with the emission limitations in section A.I.1 of these terms and conditions shall be determined in accordance with the following methods: 1.

Emission Limitation: 20% opacity as a 6-minute average for stack emissions Applicable Compliance Method: If required, compliance shall be demonstrated based upon the procedures required in 40 CFR Part 60, Appendix A, Method 9 and the methods and procedures specified in OAC rule 3745-17-03(B)(1). 1.a

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

III.Monitoring and/or Record Keeping Requirements (continued)

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

The deviation reports shall be submitted in accordance with the requirements specified in Part I - General Term and Condition A.1.c. 4.

V. Testing Requirements

Compliance with the emission limitations in section A.I.1 of these terms and conditions shall be determined in accordance with the following methods: 1.

Emission Limitation: 20% opacity as a 6-minute average for stack emissions Applicable Compliance Method: If required, compliance shall be demonstrated based upon the procedures required in 40 CFR Part 60, Appendix A, Method 9 and the methods and procedures specified in OAC rule 3745-17-03(B)(1). 1.a

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

The deviation reports shall be submitted in accordance with the requirements specified in Part I - General Term and Condition A.1.c. 4.

V. Testing Requirements

Compliance with the emission limitations in section A.I.1 of these terms and conditions shall be determined in accordance with the following methods: 1.

Emission Limitation: 20% opacity as a 6-minute average for stack emissions Applicable Compliance Method: If required, compliance shall be demonstrated based upon the procedures required in 40 CFR Part 60, Appendix A, Method 9 and the methods and procedures specified in OAC rule 3745-17-03(B)(1). 1.a

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

III.Monitoring and/or Record Keeping Requirements (continued)

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

The deviation reports shall be submitted in accordance with the requirements specified in Part I - General Term and Condition A.1.c. 4.

V. Testing Requirements

Compliance with the emission limitations in section A.I.1 of these terms and conditions shall be determined in accordance with the following methods: 1.

Emission Limitation: 20% opacity as a 6-minute average for stack emissions Applicable Compliance Method: If required, compliance shall be demonstrated based upon the procedures required in 40 CFR Part 60, Appendix A, Method 9 and the methods and procedures specified in OAC rule 3745-17-03(B)(1). 1.a

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

III.Monitoring and/or Record Keeping Requirements (continued)

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

The deviation reports shall be submitted in accordance with the requirements specified in Part I - General Term and Condition A.1.c. 4.

V. Testing Requirements

Compliance with the emission limitations in section A.I.1 of these terms and conditions shall be determined in accordance with the following methods: 1.

Emission Limitation: 20% opacity as a 6-minute average for stack emissions Applicable Compliance Method: If required, compliance shall be demonstrated based upon the procedures required in 40 CFR Part 60, Appendix A, Method 9 and the methods and procedures specified in OAC rule 3745-17-03(B)(1). 1.a

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

III.Monitoring and/or Record Keeping Requirements (continued)

The permittee shall perform weekly checks, when the emissions unit is in operation and when the weather conditions allow, for any visible particulate emissions from the stacks serving this emissions unit. The presence or absence of any visible emissions shall be noted in an operations log. If visible emissions are observed, the permittee shall also note the following in the operations log: a. the location and color of the emissions; b. whether the emissions are representative of normal operations; c. if the emissions are not representative of normal operations, the cause of the abnormal emissions; d. the total duration of any visible emission incident; and e. any corrective actions taken to eliminate the visible emissions. 3.

Notwithstanding the frequency of reporting requirements specified in section A.IV, the permittee may reduce the frequency of visual observations from weekly to once every 2 weeks for this emissions unit if the following conditions are met: a. for 1 full quarter the facility's visual observations indicate no visible emissions; and b. the permittee continues to comply with all the record keeping and monitoring requirements specified in section A.III.3. The permittee shall revert to weekly observations if any visible emissions are observed. 4.

IV.Reporting Requirements

The permittee shall submit deviation (excursion) reports that identify each day when a fuel other than natural gas was burned in this emissions unit. Each report shall be submitted within 30 days after the deviation occurs. 1. The permittee shall submit quarterly pressure drop deviation (excursion) reports that identify all periods of time during which the pressure drop across the entire EMC control system did not comply with the allowable range specified above. 2.

The permittee shall submit semiannual written reports that (a) identify all days during which any visible particulate emissions were observed from the stacks serving this emissions unit and (b) describe any corrective actions taken to eliminate the visible particulate emissions. These reports shall be submitted to the Toledo Division of Environmental Services (TDOES) by January 31 and July 31 of each year and shall cover the previous 6-month period. 3.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.

V. Testing Requirements (continued)

Emission Limitation: 0.551 lb/hr of particulate emissions Applicable Compliance Method: Compliance shall be demonstrated based upon the emission testing requirements specified in section A.V.2. 1.b

The permittee shall conduct, or have conducted, emission testing for this emissions unit in accordance with the following requirements: a. The emission testing shall be conducted within 6 months after issuance of the permit and within 6 months prior to permit expiration. If testing was performed with 12 months prior to permit issuance, and was accepted by the Ohio EPA, then additional testing within 6 months after issuance of the permit will not be required unless specifically requested by the Toledo Division of Environmental Services. b. The emission testing shall be conducted to demonstrate compliance with the particulate emission limit. c. The following test methods shall be employed to demonstrate compliance with the allowable mass emission rate: for particulates, Methods 1 through 5 of 40 CFR Part 60, Appendix A. Alternative U.S. EPA-approved test methods may be used with prior approval from the Ohio EPA. d. During each test run, the pressure drop across the entire EMC control system shall be recorded and opacity readings (using USEPA Method 9) shall be recorded for each collector. 2.

e. Emissions units P035 through P126 vent to a dirty air plenum and then are pulled through the EMC dry filter system and vent to a clean air plenum which is equipped with seven fan/stack exhaust units. Stack #30 emissions are considered typical of the seven identical units venting the combined emissions of the EMC system, but only stack 30 has been designed with the necessary facilities to safely test for emissions. The company has agreed to use a worse case factor of 1.2 times the emission rate from stack #30 (based upon flow rate testing in 1993 of the seven stacks) to be representative of each stack, in lieu of testing each stack separately. By this agreement the Ohio EPA will accept the results from the one stack test as representative of all seven. In order for compliance to be demonstrated with the allowable emission rate of 0.551 lb/hr for each emissions unit, use the following equation: [total measured emission rate from stack #30 during the test in lbs/hr] times 1.2 times [the number of fans in operation during the test] divided by [the number of emissions units operating during the test]. f. The tests shall be conducted while the emissions units are operating at or near their maximum capacities, unless otherwise specified or approved by the Toledo Division of Environmental Services. The most representative test conditions would be all 93 emissions units operating, all 13 EMC filters in the EMC system operating and all seven fan/stack exhaust units in operation.
