RE: Final Title V Chapter 3745-77 permit

Dear STEVEN SHELT:

Enclosed is the Title V permit that allows you to operate the facility in the manner indicated in the permit. Because this permit may

contain several conditions and restrictions, we urge you to read it carefully.

The Ohio EPA is encouraging companies to investigate pollution prevention and energy conservation. Not only will this reduce

pollution and energy consumption, but it can also save you money. If you would like to learn ways you can save money while

protecting the environment, please contact our Office of Pollution Prevention at (614) 644-3469.

You are hereby notified that this action of the Director is final and may be appealed to the Environmental Review Appeals Commission

pursuant to Section 3745.04 of the Ohio Revised Code. The appeal must be in writing and set forth the action complained of and the

grounds upon which the appeal is based. It must be filed with the Environmental Review Appeals Commission within thirty (30) days

after notice of the Director's action. A copy of the appeal must be served on the Director of the Ohio Environmental Protection

Agency within three (3) days of filing with the Commission. It is also requested by the Director that a copy of the appeal be served

upon the Environmental Enforcement Section of the Office of the Attorney General. An appeal may be filed with the Environmental

Review Appeals Commission at the following address:

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.

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

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 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.

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.

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 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.

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.

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.

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.

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

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

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.

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.

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.

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.

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

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.

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 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.

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.

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.

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 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.

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.

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

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.

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.

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.

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.

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 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.

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

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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 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.

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.

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

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.

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)

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.

Not later than 30 days prior to the proposed test date(s), the permittee shall submit an "Intent to Test" notification to the Toledo Division of

Environmental Services. The "Intent to Test" notification shall describe in detail the proposed test methods and procedures, the emissions

unit operating parameters, the time(s) and date(s) of the test(s), and the person(s) who will be conducting the test(s). Failure to submit such

notification for review and approval prior to the test(s) may result in the Toledo Division of Environmental Services' refusal to accept the

results of the emission test(s).

Personnel from the Toledo Division of Environmental Services shall be permitted to witness the test(s), examine the testing equipment,

and acquire data and information necessary to ensure that the operation of the emissions unit and the testing procedures provide a valid

characterization of the emissions from the emissions unit and/or the performance of the control equipment.

A comprehensive written report on the results of the emissions test(s) shall be signed by the person or persons responsible for the tests and

submitted to the Toledo Division of Environmental Services within 30 days following completion of the test(s). The permittee may request

additional time for the submittal of the written report, where warranted, with prior approval from the Toledo Division of Environmental

Services.
