3.1.156 VOC content level determination-compliant primers and topcoats.


Subject item Sec. SI. reqt SI des: SI desc Requirement and citationFor those uncontrolled primers and topcoats complying with the primer and topcoat VOC content levels specified in 40 CFR Section 63.745(c) without being averaged, the following procedure must be used to determine the mass of VOC emitted per volume of coating (less water and exempt solvents) as applied.

1) Determine the VOC content of each formulation (less water and exempt solvents) as applied using manufacturer's supplied data or Method 24 of 40 CFR pt. 60, Appendix A, to determine the VOC content. The VOC content must be used as a surrogate for total HAP content for coatings that contain no exempt solvent. If there is a discrepancy between the manufacturer's formulation data and the results of the Method 24 analysis, compliance must be based on the results from the Method 24 analysis.

When Method 24 is used to determine the VOC content of water-reducible coatings, the precision adjustment factors in Reference Method 24 must be used. If the adjusted analytical VOC content is less than the formulation solvent content, then the analytical VOC content should be set equal to the formulation solvent content.

2) For each coating applied, the Permittee must calculate the mass of VOC emitted per volume of coating (lb/gal) (less water and exempt solvents) as applied using equations 5, 6, and 7 in Appendix E of this permit. [40 CFR 63.750(e), Minn. R. 7011.7320]

3.1.157 1) If the VOC content is found to be different when EPA Method 24 is used during an enforcement inspection from that used by the Permittee in calculating Ga, compliance must be based, except as provided in 40 CFR Section 63.750(e)(3)(ii) upon the VOC content obtained using EPA Method 24.2) If the VOC content of a coating obtained using Method 24 would indicate noncompliance as determined under either 40 CFR Section 63.749 (d)(3)(i) or(d)(4)(i), the Permittee may elect to average the coating with other uncontrolled coatings and recalculate Gi (using the procedure specified in 40 CFR Section 63.750(f)), provided appropriate and sufficient records were maintained for all coatings included in the average recalculation. The recalculated value of Gi (Ga in 40 CFR Section 63.750(f)) for the averaged coatings must then be used to determine compliance. [40 CFR 63.750(e)(3), Minn. R. 7011.7320]

3.1.158 VOC content level determination-averaged primers and topcoats. For those uncontrolled primers and topcoats that are averaged within their respective coating category in order to comply with the primer and topcoat VOC content limits specified in 40 CFR Sections 63.745 (c)(2) and (c)(4), the following procedure must be used to determine the monthly volume-weighted average mass of VOC emitted per volume of coating (less water and exempt solvents) as applied, unless the MPCA specifies a shorter averaging period as part of an ambient ozone control program.

(2)(i) Determine the volume both in total gallons as applied and in total gallons (less water and exempt solvents) as applied of each coating. If any ingredients, including diluent solvents, are added prior to its application, the volume of each coating must be determined at a time and location in the process after all ingredients (including any diluent solvent) have been added.(ii) Determine the volume of each coating (less water and exempt solvents) as applied each day.(iii) The volume applied may be determined from company records. [40 CFR 63.750(f), Minn. R. 7011.7320]

Permittee With Operating Records Prior to Issuance of this Permit: The Permittee shall not exceed emissions of 25 tons per year of CO calculated as a 12-month rolling sum. Each month’s CO emissions shall be calculated with Equation B.2.1 above, and then added to the previous 11 months’ emissions.

The Permittee shall not exceed emissions of 25 tons per year of NOx calculated as a 12-month rolling sum. Each month’s NOx emissions shall be calculated with Equation B.2.1 above, and then added to the previous 11 months’ emissions.

B.3. Material Balance Calculation for Material Usage and Processing Operations

This includes use of paints, thinners, abrasive blasting material, etc. that can use the provided calculation methods. Emission Unit, which qualify as insignificant activities or fugitive sources do not need to be included in the calculations.

B.3.1 Demonstration of Compliance with Permit Limits

Permittee With At Least 12 Months of Operating Records. Each month, the Permittee shall use the directions in this Appendix to calculate the 12-month rolling sum of the Particulate Matter, VOC, Total HAP, and Single HAP emissions from material usage and processing operations to demonstrate compliance with the limits of this permit. The Permittee shall use their actual operating history to calculate the 12-month rolling sum.

Permittee Without 12 Months of Operating Records. Each month, the Permittee shall use the directions in this Appendix to calculate the monthly emissions of the Particulate Matter, VOC, Total HAP, and Single HAP emissions in tons/month from material usage and processing operations to demonstrate compliance with the limits of this permit. The Permittee shall evaluate their compliance based on the months for which they have operating data. The Permittee must then use Table B.1 above to determine if they are under the applicable emission limit. For example, if the Permittee has 3 months of operating data, the Permittee shall sum the monthly emissions for the most recent month and the previous 2 months, and compare the resulting number to the applicable limit in row 3 of Table B.1. Once the Permittee has 12 months of data, then the Permittee must calculate the 12-month rolling sum of the emissions each month, as required above.

B.3.2 Material Content Identification

http://www.epa.gov/climateleadership/documents/emission-factors.pdf

http://www.epa.gov/otaq/retrofit/techlist-biodiesel.htm


If the information is necessary for the Permittee’s calculation method, the material specifications (VOC content, Solids content etc.) shall be determined by the Safety Data Sheet (SDS), Material Safety Data Sheet (MSDS), or Certification of Analysis (COA) provided by the supplier. If a content range is given on the SDS, MSDS, or COA the highest number in the range shall be used for the compliance calculations. If there is information provided in the Regulatory Section of the SDS, the highest number in the range of that section may be used. Other alternative methods approved by the MPCA may be used to determine the material contents.

Considerations for Particulate Matter/Solids Contents Each month, identify the Particulate Matter (PM, PM<10 microns, and PM<2.5 microns) contents in

coating materials and other material-usage operations in lbs of Particulate Matter (also known as Solids) per gallon of material, for each material used at the facility.

When using the SDS or MSDS as the basis of this determination, the Permittee can assume that PM consists entirely of PM < 2.5 microns, meaning PM is equal to PM10 is equal to PM2.5.

The Permittee may choose to assume that any or all materials used at their facility consist of 100% Solids/Particulate Matter, as long as the Permittee can remain under the limits of the permit while using that assumption. If a material is assumed to be 100% Solids, then the Solids content is the density of the material in lbs/gallon.

For some material processing operations (blasting, sanding, grinding etc.) the material used or processed may be 100% Solids/Particulate Matter.

Considerations for VOC Contents Each month, identify the Volatile Organic Compound (also known as V.O.C. or VOC) contents in

coating materials and other material-usage operations in lbs of VOC per gallon of material, for each material used at the facility.

The Permittee may choose to assume that any or all materials used at their facility consist of 100% VOC, as long as the Permittee can remain under the limits of the permit while using that assumption. If a material is assumed to be 100% VOC, then the VOC content is the density of the material in lbs/gallon.

Considerations for HAP Contents For each month in which the Permittee determines that the 12-month sum of the VOC emissions is

less than the single HAP limit (5.0 tons based on a 12-month rolling sum) as calculated in Section 3.4 of this TSD, the Permittee can choose to assume that the 12-month sum of the Total HAP and Single HAP emissions are also 5.0 tons. For that month the Total and Single HAP emissions calculation is not required.

For each month in which the Permittee determines that the 12-month sum of the VOC emission is greater than 5.0 tons, the Permittee must determine the HAP content and calculate the HAP emissions as indicated below.

For each month that the calculation is required, identify each individual Hazardous Air Pollutant (also known as HAP) content in each coating material or other material. Record the name of each individual HAP (such as toluene, xylene, ethyl benzene etc.) and the contents of that HAP in lbs of HAP per gallon of material, for each material used at the facility. Note than non-HAP material (as defined in 40 CFR 63.742) is excluded from the 12-month rolling average calculation, unless the Permittee includes non-HAP material where compliance is being achieved through the use of averaging.


B.3.3 PM, PM<10 microns, and PM<2.5 microns Emissions Based on a 12-month rolling sum

STEP 1: Calculation of Solids/Particulate Matter Used each Month (Solids Usage)

The Permittee shall calculate the total amount of Solids used or processed during a calendar month using records of hourly usage rate, daily material usage, hours of operations, purchase records, or any combination of methods as identified in the permit application or Compliance Management Plan. Depending on the calculation basis previously identified, the Permittee may use one or more of the following example calculation methods, or a similar method, to determine monthly usage in lbs Solids/month. Method 1 and 2 may be more useful for coating operations where the solids content in lbs/gallon is known. Methods 3 and 4 may be more useful for operations where a 100% Solids material is used, such as in abrasive blasting, and the weight of the material used or purchased hourly or daily is known.

Method 1: Solids Usage (S) based on hourly usage rate (such as spray gun capacity), hours of operation, and SDS/MSDS

S=A×B×CWhere:S = Solids Usage in lbs Solids/monthA = rate of material usage (i.e. spray gun capacity) in gallons/hourB = solids content of material from SDS or MSDS, as identified in Section B.3.2 (lb Solids/gallon of material)C = actual hours of operation for the previous month

Method 2: Solids Usage based on gallons of material used or purchased each day, days of operation, and SDS/MSDS

S=A×B×CWhere:S = Solids Usage in lbs Solids/monthA = average gallons of material used or purchased per dayB = solids content of material from SDS or MSDS, as identified in Section B.3.2 (lbs solids/gallon of material)C = actual days of operation for the previous month

Method 3: Material Usage based on hourly usage or processing, hours of operation, and an Emission Factor (EF)

S=A× EF×CWhere:S = Solids Usage in lbs Solids/monthA = lb of material (i.e. abrasive) used per hourEF = Emission Factor (lb PM/lb material) identified in permit application or Compliance Management Plan

(see Table B.3.1 below for abrasive blasting EFs). The emission factors for PM, PM<10 microns, and PM<2.5 microns may be pollutant specific.

C = actual hours of operation for the previous month


Method 4: Solids Usage based on material used or purchased each day, days of operation, and an Emission Factor (EF)

S=A× EF×CWhere:S = Solids Usage in lbs Solids/monthA = lb of material (i.e. abrasive) used or purchased per dayEF = Emission Factor (lb PM/lb material) identified in permit application or Compliance Plan (see Table

B.3.1 below for abrasive blasting Emission Factors)C = actual days of operation for the previous month

Table B.3.1Emission Factor

Abrasive lb PM / lb abrasive lb PM10 /lb abrasiveSand 0.041 0.029Grit 0.010 0.0070Steel Shot 0.004 0.0034Other 0.010 0.00010

Emissions factors for PM, PM<10 microns, and PM<2.5 microns emissions from abrasive blasting obtained from Volume I of STAPPA-ALAPCO "Air Quality Permits". PM<2.5 microns is assumed to be equivalent to PM<10 microns.

STEP 2: Identify Transfer Efficiency and Overall Control Efficiency as applicable

Transfer EfficiencySelect a Transfer Efficiency if one of the application methods in Table B.3.2 is used. These are the transfer efficiencies allowed by this permit for these application methods. Alternatively, the Permittee may choose to use a transfer efficiency of zero, as long as the Permittee can remain under the limits of the permit while using that assumption. For operations not identified in Table B.3.2, transfer efficiency is assumed to be zero.

Table B.3.2Application Method Transfer EfficiencyAir atomization spray Not allowedAirless spray 0.45Electrostatic/Air atomization 0.70Electrostatic/Airless 0.75High Volume Low Pressure 0.75Electrode deposition 0.95Powder 0.95

Overall Control EfficiencyCalculate the Overall Control Efficiency for PM, PM<10 microns, and PM<2.5 microns. This calculation shall be used as indicated in your Compliance Management Plan, if applicable.


Considerations for Overall Control Efficiency: The Permittee may choose to use an Overall Control Efficiency of zero, as long as the Permittee can

remain under the limits of the permit while using that assumption. For operations that do not use control equipment, the Overall Control Efficiency is zero. For operations that are totally enclosed as defined in Section 5 this permit, the Capture Efficiency (C) is

100%. For operations that are not totally enclosed, but are certified according to Minn. R. 7011.0072, the

Capture Efficiency (C) is 80%. For operations that are not totally enclosed, and are not certified according to Minn. R. 7011.0072,

the Overall Control Efficiency is zero. The Collection used in this equation will depend on the type of control equipment used. The Control for PM, PM<10 microns, and PM<2.5 microns as controlled by different types of control

equipment are listed Minn. R. 7011.0070 and Section 5 of this permit. Note: If the Permittee accounts for control for PM then the PM, PM<10 microns, and PM<2.5 microns

emissions must be determined separately from this point on, since there are different control efficiencies for each type of particulate matter.

OverallControl Efficiency (%)=C ×DWhere:C = Capture efficiency (% capture). D = Collection efficiency (% collection).

STEP 3: Calculate lb of Particulate Matter PM, PM<10 microns and PM<2.5 microns per month

This equation gives PM, PM<10 microns, and PM<2.5 microns emitted in lbs/month using the Solids/month (S) identified in STEP 1, and taking into account any transfer efficiency or control efficiency identified in STEP 2.

Monthly Emissions=S× (1−Transfer Efficiency )×( 100−(OverallControl Efficiency)100 )

Where:Monthly Emissions = Particulate Matter PM, PM<10 microns, and PM<2.5 microns emissions in lbs/monthS = lbs Solids/month as determined in STEP 1Transfer Efficiency = Transfer Efficiency as identified in STEP 2 (this may be zero)Overall Control Efficiency = % Overall Control Efficiency as identified in STEP 2 (this may be zero)

STEP 4: Determine the Total Monthly Emissions

If more than one Solids-emitting process, or materials with different solids contents, are used at the facility, and consequently more than one method was used to determined monthly emissions, at this point the monthly emission from each process or material should be summed to determine the Total monthly PM, PM<10 microns, and PM<2.5 microns emissions. If PM, PM<10 microns, and PM<2.5 microns 5 are not considered to be equal, then a total monthly emissions should be calculated separately for PM, PM<10 microns, and PM<2.5 microns.

STEP 5: Identify Material Shipped as Waste, as applicable


The Permittee may elect to obtain credit for solids shipped in waste materials by one of the following methods:

1. The Permittee may analyze a composite sample of each waste shipment to determine the weight content of Solids in lbs/gallon.

2. The Permittee may use supplier data for raw materials to determine the solids content of each waste shipment, using the same content data used to determine the content of raw materials. If the waste contains several materials, the content of mixed waste shall be assumed to be the lowest solids content of any of the materials.

Once Solids content is identified, use a calculation method to determine waste (W) in lbs Solids/month.For example:W=X ×YWhere:W = Waste shipped in lbs Solids/monthX = Solids content of the waste in lbs Solids/gallonY = Total amount of waste, in gallons, shipped that month

STEP 6: Calculate tons Particulate Matter (PM, PM<10 microns and PM<2.5 microns) per month

PM=[T−W ]×0.0005Where:PM = Emission of Particulate Matter PM, PM<10 microns, and PM<2.5 microns in tons/monthT = Total monthly emission of Particulate Matter in lb/month as determined in STEP 4W = waste shipped in lbs Solids/month as determined in STEP 5 (if no waste credit is taken, this will be zero)0.0005 = conversion factor; ton/pounds (ton/lbs)

STEP 7: Calculate the 12-month rolling sum of Particulate Matter

Each month, the Permittee shall calculate the 12-month rolling sum PM, PM<10 microns, and PM<2.5 microns emissions for the previous 12-month period by summing the monthly PM emissions data, as calculated in STEP 6, for the previous 12 months.

B.3.4 VOC Emissions Based on a 12-month rolling sum

STEP 1: Calculation of Volatile Organic Carbon (VOC) Used Each Month

The Permittee shall calculate the total amount of VOCs used or processed during a calendar month using records of hourly usage rate, daily material usage, hours of operations, purchase records, or any combination of methods as identified in the permit application or Compliance Management Plan. Depending on the calculation basis previously identified, the Permittee may use one or more of the following example calculation methods, or a similar method, to determine monthly usage in lbs VOC/month.

Method 1: VOC Usage (V) based on hourly usage rate (such as spray gun capacity), hours of operation, and SDS/MSDS


V=A×B×CWhere:V = VOC Usage in lbs VOC/monthA = rate of VOC-containing material usage (i.e. spray gun capacity) in gallons/hourB = VOC content of material from SDS or MSDS, as identified in Section B.3.2 (lb VOC/gallon of material)C = actual hours of operation for the previous month

Method 2: VOC Usage based on gallons of material used or purchased each day, days of operation, and SDS/MSDS

V=A×B×CWhere:V = VOC usage in lbs VOC/monthA = average gallons of VOC-containing material used or purchased per dayB = VOC content of material from SDS or MSDS, as identified in Section B.3.2 (lbs VOC/gallon of material)C = actual days of operation for the previous month

STEP 2: Calculate lb of VOC emissions per month

This equation gives VOC emitted in lbs/month using the lb VOC/month (V) identified in STEP 1,

STEP 3: Determine the Total Monthly Emissions

If more than one VOC-emitting process, or materials with different VOC contents, are used at the facility, and consequently more than one method was used to determined monthly emissions, at this point the monthly emission from each process or material should be summed to determine the Total monthly VOC emissions.


The Permittee may elect to obtain credit for VOCs shipped in waste materials by one of the following methods:

1. The Permittee may analyze a composite sample of each waste shipment to determine the weight content of VOCs in lbs/gallon.

2. The Permittee may use supplier data for raw materials to determine the VOC content of each waste shipment, using the same content data used to determine the content of raw materials. If the waste contains several materials, the content of mixed waste shall be assumed to be the lowest VOC content of any of the materials.

Once VOC content of the waste is identified, use a calculation method to determine waste (W) in lbs VOC/month.

For example:W=X ×YWhere:


W = Waste shipped in lbs VOC/monthX = VOC content of the waste in lbs VOC/gallonY = Total amount of waste, in gallons, shipped that month

STEP 5: Calculate tons VOC per month

VOC=[T−W ]×0.0005Where:VOC = Emission of VOC in tons/monthT = Total monthly emission of VOCs in lbs VOC/month as determined in STEP 3W = waste shipped in lbs VOC/month as determined in STEP 4 (if no waste credit is taken, this will be zero)0.0005 = conversion factor; ton/pounds (ton/lbs)

STEP 6: Calculate the 12-month rolling sum of VOC

Each month, the Permittee shall calculate the 12-month rolling sum VOC emissions for the previous 12-month period by summing the monthly VOC emissions data, as calculated in STEP 5, for the previous 12 months.

B.3.5 HAP Emissions Based on a 12-month rolling sum

STEP 1: Calculation of HAP Used each Month

The Permittee shall calculate the amount of each individual HAPs used or processed during a calendar month using records of hourly usage rate, daily material usage, hours of operations, purchase records, or any combination of methods as identified in the permit application or Compliance Management Plan. The Permittee may use emissions factors. The Permittee may calculate an organic HAP emission factor based on the equations in 40 CFR pt. 63, subp. GG, or the Permittee may use any organic HAP emissions factor approved by US EPA, such as factors from AP–42, or site-specific organic HAP emissions factors if approved by the MPCA. Depending on the calculation basis previously identified, the Permittee may use one or more of the following example calculation methods, or a similar method, to determine monthly usage in lbs HAP/month. Method 1 and 2 may be more useful for coating operations where the HAP content in lbs/gallon is known. Methods 3 and 4 may be more useful for operations where an emission factor can be used, such as in open molding or centrifugal casting operations and the weight of the material used or purchased hourly or daily is known.

The monthly emissions must be determined individually for each type of HAP used.

Method 1: HAP Usage (H) based on hourly usage rate (such as spray gun capacity), hours of operation, and SDS/MSDS

H=A×B×CWhere:H = HAP Usage in lbs HAP/monthA = rate of material usage (i.e. spray gun capacity) in gallons/hourB = HAP content of material from SDS or MSDS, as identified in Section B.3.2 (lb HAP/gallon of material)


C = actual hours of operation for the previous month

Method 2: HAP Usage based on gallons of material used or purchased each day, days of operation, and SDS/MSDS

H=A×B×CWhere:H = HAP Usage in lbs HAP/monthA = average gallons of material used or purchased per dayB = HAP content of material from SDS or MSDS, as identified in Section B.3.2 (lb HAP/gallon of material)C = actual days of operation for the previous month

Method 3: HAP Usage based on lbs of material processed per hour, hours of operation, and an Emission Factor (EF) in lb HAP per lb of material

H=A× EF×CWhere:H = HAP Usage in lbs HAP/monthA = lb of material (i.e. resin or coating) used per hourEF = Emission Factor in lb HAP/lb material identified in permit application or Compliance Management

Plan C = actual hours of operation for the previous month

Method 4: HAP Usage based on tons of material processed per hour, hours of operation, and an Emission Factor (EF) in lbs HAP per ton of material

H=A× EFWhere:H = HAP Usage in lbs HAP/monthA = tons of material (i.e. resin or coating) used in the previous monthEF = Emission Factor in lb HAP/ton material as identified in permit application or Compliance

Management Plan


The Permittee can choose to take credit for HAPs shipped in waste materials. This can be done for each Individual HAP, for Total HAPs only, or for both. If credit is taken the amount of HAPs shipped in waste materials must be determined by one of the following methods:

1. The Permittee may analyze a composite sample of each waste shipment to determine the weight content of HAPs in lbs/gallon (each individual HAP in lbs/gallon, or Total HAP in lb/gallon).

2. The Permittee may use supplier data for raw materials to determine the (Total or Individual) HAP content of each waste shipment, using the same content data used to determine the content of raw materials. If the waste contains several materials, the content of mixed waste shall be assumed to be the lowest HAP content of any of the materials.


Once HAP content of the waste is identified, use a calculation method to determine waste (W) in lbs HAP/month.

For example:W=X ×YWhere:W = Waste shipped in lbs HAP/monthX = Total or Individual HAP content of the waste in lbs HAP/gallonY = Total amount of waste, in gallons, shipped that month

STEP 3: Calculate the sum of Total and Individual HAPs emitted per month in lb HAP/month

Individual (Single) HAP:At this point the Permittee should sum up the total amount of each type of HAP used in different processes, or from different material. For example, if two different coating materials were used in the same month for the same process, but in different amounts, and both materials contain Ethylbenzene, then the total amount of Ethylbenzene used during the month will be the sum of the lb/month calculated previously from each material.

Total HAP:At this point the Permittee should sum up the Total HAP emitted in lb Total HAP/month. This is the sum of all Individual HAPs emitted from all the different processes and materials at the source.

STEP 4: Calculate tons Total and Individual HAP emitted per month

This should be calculated separately for each type of HAP, and for Total HAPs.

HAP=[T−W ]×0.0005Where:HAP = Emissions of Total or Individual HAP in tons/month in STEP 1T = Total monthly emission of Total or Individual HAP in lb HAP/month as determined in STEP 3W = waste shipped in lbs HAP/month as determined in STEP 2 (if no waste credit is taken, this will be zero)0.0005 = conversion factor; ton/pounds (ton/lbs)

STEP 5: Calculate the 12-month rolling sum of Total and Individual (Single) HAP

Each month, the Permittee shall calculate the 12-month rolling sum HAP emissions for the previous 12-month period by summing the monthly HAP emissions data, as calculated in STEP 4, for the previous 12 months. To determine compliance with the Single HAP limit (5.0 tons/year) the Permittee shall use the highest number from the Individual HAP (the type of HAP that had the greatest emissions in the 12-month period) to compare to the limit.

Table C2. – General Provisions Requirements

Requirement & Citation

Circumvention: The Permittee shall not build, erect, install, or use any article, machine, equipment, or process to conceal an emission that would otherwise constitute noncompliance with a relevant standard. Such concealment includes, but is not limited to:

1) The use of diluents to achieve compliance with a relevant standard based on the concentration of a pollutant in the effluent discharged to the atmosphere or

2) The use of gaseous diluents to achieve compliance with a relevant standard for visible emissions. [40 CFR 63.4(b), Minn. R. 7011.7000]Prior to construction or reconstruction of a major-emitting "affected source" under the promulgated MACT standards, the Permittee shall apply for and obtain an air emission permit. [40 CFR 63.5(b)(3), Minn. R. 7011.7000]

After the effective date of any relevant standard promulgated by the Administrator under 40 CFR pt. 63, the Permittee who constructs a new affected source that is not major-emitting or reconstructs an affected source that is not major-emitting that is subject to such standard, or reconstructs a source such that the source becomes an affected source subject to the standard, must notify the Administrator of the intended construction or reconstruction. The notification must be submitted in accordance with the procedures in 40 CFR Section 63.9(b). [40 CFR 63.5(b)(4), Minn. R. 7011.7000]After the effective date of any relevant standard promulgated by the Administrator under 40 CFR pt. 63, equipment added (or a process change) to an affected source that is within the scope of the definition of affected source under the relevant standard must be considered part of the affected source and subject to all provisions of the relevant standard established for that affected source. [40 CFR 63.5(b)(6), Minn. R. 7011.7000]Proper Operation and Maintenance. At all times, including periods of startup, shutdown, and malfunction, the Permittee shall operate and maintain the emission unit subject to the MACT standard and any associated air pollution control equipment and monitoring equipment, in a manner consistent with safety and good air pollution control practices for minimizing emissions at least to the levels required by any relevant standard and as detailed in 40 CFR Section 63.6(e)(1)(i)-(iii).

Each run shall be conducted for the time and under the conditions specified in the relevant standard. For the purpose of determining compliance with a relevant standard, the arithmetic mean of the results of the three runs shall apply, unless otherwise approved in accordance with provisions of 40 CFR Section 63.7(e)(3). [40 CFR 63.7(e)(3), Minn. R. 7017.2015]Data analysis, recordkeeping, and reporting. Unless otherwise specified in a relevant standard or test method, or as otherwise approved by the Administrator in writing, results of a performance test shall include the analysis of samples, determination of emissions, and raw data. A performance test is “completed” when field sample collection is terminated. The Permittee shall report the results of the performance test to the Administrator before the close of business on the 60th day following the completion of the performance test, unless specified otherwise in a relevant standard or as approved otherwise in writing. The results of the performance test shall be submitted as part of the notification of compliance status required under 40 CFR Section 63.9(h) to the appropriate permitting authority. [40 CFR 63.7(g), Minn. R. 7017.2015]Conduct of monitoring. Monitoring shall be conducted as set forth in 40 CFR Section 63.8(a)(b)(1). When the emissions from two or more affected sources are combined before being released to the atmosphere, the Permittee may install an applicable CMS for each emission stream or for the combined emissions streams, provided the monitoring is sufficient to demonstrate compliance with the relevant standard unless other approved in accordance with 40 CFR Section 63.8(a)(b)(2). [40 CFR 63.8(b), Minn. R. 7017.2015]Operation and maintenance of continuous monitoring systems. The Permittee shall maintain and operate each CMS in a manner consistent with good air pollution control practices. [40 CFR 63.8(c)(1), Minn. R. 7017.2015]Operation and maintenance of continuous monitoring systems. The Permittee shall maintain and operate each CMS as specified in 40 CFR Section 63.6(e)(1). [40 CFR 63.8(c)(1)(i), Minn.

[40 CFR 63.8(c)(2)-(4), Minn. R. 7017.2015]Operation and maintenance of continuous monitoring systems. Unless otherwise approved, minimum procedures for COMS shall include a method for producing a simulated zero opacity condition and an upscale (high-level) opacity condition using a certified neutral density filter or other related technique to produce a known obscuration of the light beam. [40 CFR 63.8(c)(2)-(4), Minn. R. 7017.2015]Operation and maintenance of continuous monitoring systems.

1) The Permittee of a CMS that is not a CPMS, must check the zero (low-level) and high-level calibration drifts at least once daily in accordance with the written procedure specified in the performance evaluation plan.

2) A CMS is out of control if:

i) The zero (low-level), mid-level (if applicable), or high-level calibration drift (CD) exceeds two times the applicable CD specification in the applicable performance specification or in the relevant standard; or

ii) The CMS fails a performance test audit (e.g., cylinder gas audit), relative accuracy audit, relative accuracy test audit, or linearity test audit; or

iii) The COMS CD exceeds two times the limit in the applicable performance specification in the relevant standard.

When the CMS is out of control, the Permittee shall take the necessary corrective action and shall repeat all necessary tests which indicate that the system is out of control until the performance requirements are below the applicable limits. The beginning of the out-of-control period is the hour the Permittee conducts a performance check (e.g., calibration drift) that indicates an exceedance of the performance requirements established under this part. The end of the out-of-control period is the hour following the completion of corrective action and successful demonstration that the system is within the allowable limits. During the period the CMS is out of control, recorded data shall not be used in data averages and calculations, or to meet any data availability requirement established under this part

3) The Permittee shall submit all information concerning out-of-control periods, including start and end dates and hours and descriptions of corrective actions taken, in the excess emissions and continuous monitoring system performance report.

[40 CFR 63.8(c)(6)-(8), Minn. R. 7017.2015]


The Permittee shall develop and implement a CMS quality control program. As part of the quality control program, the Permittee shall develop and submit to the Administrator for approval upon request a site-specific performance evaluation test plan for the CMS performance evaluation required in 40 CFR Section 63.8(e)(3)(i). Each quality control program shall include, at a minimum, a written protocol that describes procedures for each of the following operations:

(i) Initial and any subsequent calibration of the CMS;

(ii) Determination and adjustment of the calibration drift of the CMS;

(iii) Preventive maintenance of the CMS, including spare parts inventory;

(iv) Data recording, calculations, and reporting;

(v) Accuracy audit procedures, including sampling and analysis methods; and

vi) Program of corrective action for a malfunctioning CMS.

The Permittee shall keep these written procedures on record for the life of the affected source, to be made available for inspection, upon request. The Permittee shall keep previous versions of the performance evaluation plan on record to be made available for inspection upon request, for a period of 5 years after each revision to the plan. [40 CFR 63.8(d), Minn. R. 7017.2015]Performance evaluation of continuous monitoring systems

1) When required by a relevant standard, and at any other time the Administrator may require, the Permittee shall conduct a performance evaluation of the CMS according to the applicable specifications and procedures described in 40 CFR Section 63.8(e) or in the relevant standard.

2) Notification of performance evaluation. The Permittee shall notify the Administrator in writing of the date of the performance evaluation simultaneously with the notification of the performance test date or at least 60 days prior to the date the performance evaluation is scheduled to begin if no performance test is required.

3) Reporting performance evaluation results. The Permittee shall furnish the Administrator a copy of a written report of the results of the performance evaluation simultaneously with the results of the performance test or within 60 days of completion of the performance evaluation if no test is required, unless otherwise specified in a relevant standard.
