COMPLIANCE REQUIREMENTS hdr

Best management practices for paint stripping operations: Each affected area source must implement management practices to minimize the evaporative emissions of MeCl. The management practices must address, at a minimum, the following practices as applicable for the operations at the affected facility.

1. Evaluate each application to ensure there is a need for paint stripping (e.g., evaluate whether it is possible to re-coat the piece without removing the existing coating).

2. Evaluate each paint stripper operation containing MeCl is used to ensure that there is no alternative paint stripping technology that can be used.

3. Reduce exposure of all paint strippers containing MeCl to the air.4. Optimize application conditions when using paint strippers containing

MeCl to reduce MeCl evaporation (e.g., if the stripper must be heated, make sure that the temperature is kept as low as possible to reduce evaporation).

5. Practice proper storage and disposal of paint strippers containing MeCl (e.g., store stripper in closed, air-tight containers).

40 CFR Section 63.11173(a)

Paint stripping operations with MeCl usage over 1 ton per year: Each paint stripping operation that has annual usage of more than one ton of MeCl must develop and implement a written plan to minimize the use and emissions of MeCl. The MeCl minimization plan must address, at a minimum, the management practices specified in paragraphs 1 through 5 above, as applicable for operations at the affected facility. Each operation must post a placard or sign outlining the MeCl minimization plan in each area where paint stripping operations subject to this subpart occur.

Each operation with annual usage of more than one ton of MeCl must maintain a copy of their current MeCl minimization plan on site at all times.

40 CFR Sections 63.11173(b) and (d)

Certification for surface coating operations: Each surface coating operation must ensure that all painters have been certified by completing training in the proper spray application of surface coatings and the proper setup and maintenance of spray equipment. The minimum requirements for training and certification are described in the training program requirements section below. The spray application of surface coatings is prohibited by persons who are not certified as having completed the training. The requirements do not apply to the students of an accredited surface coating training program who are under the direct supervision of an instructor who meets the certification requirements.

40 CFR Section 63.11173(e)(1)

Enclosure requirements for surface coating operations: Each surface coating operation must meet the following requirements.

All spray-applied coatings must be applied in a spray booth, preparation station, or mobile enclosure that meets the requirements of paragraph i of this section and either paragraph ii, iii, or iv of this section as applicable.

i. All spray booths, preparation stations, and mobile enclosures must be fitted with a type of filter technology that is demonstrated to achieve at least 98-percent capture of paint overspray. The procedure used to demonstrate filter efficiency must be consistent with the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Method 52.1, “Gravimetric and Dust-Spot Procedures for Testing Air-Cleaning Devices Used in General Ventilation for Removing Particulate Matter, June 4, 1992” (see 40 CFR Section 63.14). The test coating for measuring filter efficiency shall be a high solids bake enamel delivered at a rate of at least 135 grams per minute from a conventional (non-HVLP) air-atomized spray gun operating at 40 pounds per square inch (psi) air pressure; the air flow rate across the filter shall be 150 feet per minute. The Permittee may use published filter efficiency data provided by filter vendors to demonstrate compliance with this requirement and are not required to perform this measurement. The requirements of this paragraph do not apply to waterwash spray booths that are operated and maintained according to the manufacturer's specifications.

ii. Spray booths and preparation stations used to refinish complete motor vehicles or mobile equipment must be fully enclosed with a full roof, and four complete walls or complete side curtains, and must be ventilated at negative pressure so that air is drawn into any openings in the booth walls or preparation station curtains. However, if a spray booth is fully enclosed and has seals on all doors and other openings and has an automatic pressure balancing system, it may be operated at up to, but not more than, 0.05 inches water gauge positive pressure.

iii. Spray booths and preparation stations that are used to coat miscellaneous parts and products or vehicle subassemblies must have a full roof, at least three complete walls or complete side curtains, and must be ventilated so that air is drawn into the booth. The walls and roof of a booth may have openings, if needed, to allow for conveyors

aq-12-01n • 4/30/15 Page 48

and parts to pass through the booth during the coating process.iv. Mobile ventilated enclosures that are used to perform spot repairs must

enclose and, if necessary, seal against the surface around the area being coated such that paint overspray is retained within the enclosure and directed to a filter to capture paint overspray.

Transfer efficiency requirements for surface coating operations: All spray-applied coatings must be applied with a high volume, low pressure (HVLP) spray gun, electrostatic application, airless spray gun, air-assisted airless spray gun, or an equivalent technology that is demonstrated by the spray gun manufacturer to achieve transfer efficiency comparable to one of the spray gun technologies listed above for a comparable operation, and for which written approval has been obtained from the Administrator.

The procedure used to demonstrate that spray gun transfer efficiency is equivalent to that of an HVLP spray gun must be equivalent to the California South Coast Air Quality Management District's “Spray Equipment Transfer Efficiency Test Procedure for Equipment User, May 24, 1989” and “Guidelines for Demonstrating Equivalency with District Approved Transfer Efficient Spray Guns, September 26, 2002.”

The requirements of this paragraph do not apply to painting performed by students and instructors at paint training centers. The requirements of this paragraph do not apply to the surface coating of aerospace vehicles that involves the coating of components that normally require the use of an airbrush or an extension on the spray gun to properly reach limited access spaces; to the application of coatings on aerospace vehicles that contain fillers that adversely affect atomization with HVLP spray guns; or to the application of coatings on aerospace vehicles that normally have a dried film thickness of less than 0.0013 centimeter (0.0005 in.).

40 CFR Section 63.11173(e)(3)

Spray gun cleaning requirements for surface coating operations: Each operation must meet the following requirements.

All paint spray gun cleaning must be done so that an atomized mist or spray of gun cleaning solvent and paint residue is not created outside of a container that collects used gun cleaning solvent. Spray gun cleaning may be done with, for example, hand cleaning of parts of the disassembled gun in a container of solvent, by flushing solvent through the gun without atomizing the solvent and paint residue, or by using a fully enclosed spray gun washer. A combination of non-atomizing methods may also be used.

40 CFR Section 63.11173(e)(4)

Training program requirements for surface coating operations: The Permittee must ensure and certify that all new and existing personnel, including contract personnel, who spray apply surface coatings, as defined above, are trained in the proper application of surface coatings.

JJ.

Incidental wood furniture manufacturer: a major source of HAP that is primarily engaged in the manufacture of products other than wood furniture or wood furniture components and that uses no more than 100 gallons per month of finishing material or adhesives in the manufacture of wood furniture or wood furniture components.

40 CFR Section 63.800; 40 CFR Section 63.801(a); Minn. R. 7011.7340

SMALL SOURCE: A source that complies with all of the limits and criteria specified in paragraphs 1) - 3) below is an area source for the purposes of this subpart and is not subject to any other provisions of 40 CFR pt. 63, subp. JJ, provided that:

In the case of paragraphs 1) and 2), finishing materials, adhesives, cleaning solvents and washoff solvents used for wood furniture or wood furniture component manufacturing operations account for at least 90 percent of annual HAP emissions at the plant site, and if the plant site has HAP emissions that do not originate from the listed materials, the Permittee

40 CFR section 63.800(b) and (f); Minn. R. 7011.7340

aq-12-01n • 4/30/15 Page 57


shall keep any records necessary to demonstrate that the 90 percent criterion is being met.

A source that initially relies on the limits and criteria specified in paragraphs 1), 2), and 3) to avoid applicability of 40 CFR pt. 63, subp. JJ, but subsequently exceeds the relevant limit (without first obtaining and complying with other limits that keep its potential to emit hazardous pollutants below major source levels), must comply thereafter with all applicable provisions of this subpart within one year of becoming a major source.

Nothing in this requirement precludes a source from limiting its potential to emit through other appropriate mechanisms.

Paragraphs 1) - 3) below require the Permittee to maintain certain records. The Permittee shall maintain these records for five years. Upon request, the Permittee shall submit such records to the Administrator. A rolling 12-month period consists of 12 consecutive calendar months, and includes the previous 12 months of operation.

1) Limit: The Permittee shall use no more than 250 gallons per month, for every month, of coating, gluing, cleaning, and washoff materials at the source, including materials used for source categories other than wood furniture (surface coating), but excluding materials used in routine janitorial or facility grounds maintenance, personal uses by employees or other persons, the use of products for the purpose of maintaining motor vehicles operated by the facility, or the use of toxic chemicals contained in intake water (used for processing or noncontact cooling) or intake air (used either as compressed air or for combustion).

Recordkeeping: By the 15th of each month, the Permittee shall record and maintain the total gallons of coating, gluing, cleaning, and washoff materials used during the previous month.

2) Limit: The Permittee shall use no more than 3,000 gallons per rolling 12-month period, for every 12-month period, of coating, gluing, cleaning, and washoff materials at the source, including materials used for source categories other than wood furniture (surface coating), but excluding materials used in routine janitorial or facility grounds maintenance, personal uses by employees or other persons, the use of products for the purpose of maintaining motor vehicles operated by the facility, or the use of toxic chemicals contained in intake water (used for processing or noncontact cooling) or intake air (used either as compressed air or for combustion).

Recordkeeping: By the 15th of each month, the Permittee shall record and maintain the total gallons of coating, gluing, cleaning, and washoff materials used during the previous rolling 12-month period by summing the monthly usage totals during those months. Because records are needed over the previous set of 12 months, the Permittee shall keep monthly records beginning no less than one year before the compliance date specified in 40

aq-12-01n • 4/30/15 Page 58


CFR Section 63.800(e). Note: all compliance dates have passed.

3) Limit: The source shall emit no more than 5 tons of any one HAP per rolling 12-month period and no more than 12.5 tons of any combination of HAP per rolling 12-month period, and at least 90 percent of the plantwide emissions per rolling 12-month period are associated with the manufacture of wood furniture or wood furniture components.

and cleaning materials are stored or mixed;8) All manual and automated equipment and containers used for conveying coatings, thinners

and/or other additives, and cleaning materials; and9) All storage containers and all manual and automated equipment and containers used for

conveying waste materials generated by a coating operation.

New Source: commenced construction or reconstruction after August 13, 2002

Existing Source: commenced construction or reconstruction on or before August 13, 2002

(Also see 40 CFR Section 63.3882(c))

Compliance dates: All compliance dates have passed for this standard. For existing affected sources, the compliance date was January 2, 2007. For new affected sources, the compliance date was January 2, 2004, or the date of initial startup of the affected source, whichever was later.

(Also see 40 CFR Section 63.3883 and 40 CFR Sections 63.6(b) and (c))

The Permittee is subject to the requirements below if the Permittee owns or operates a new, reconstructed, or existing affected source that uses 250 gallons or more per year of coatings that contain hazardous air pollutants (HAP) in the surface coating of miscellaneous metal parts and products. The Permittee is not required to include coatings that meet the definition of non-HAP coating contained in 40 CFR Section 63.3981 in determining whether 250 gallons, or more, of coatings in the surface coating of miscellaneous metal parts and products is used.


Miscellaneous metal parts and products include, but are not limited to: Metal components of the following types of products as well as the products themselves: motor vehicle parts and accessories, bicycles and sporting goods, recreational vehicles, extruded aluminum structural components, railroad cars, heavy duty trucks, medical equipment, lawn and garden equipment, electronic equipment, magnet wire, steel drums, industrial machinery, metal pipes, and numerous other industrial, household, and consumer products.

Coating operation: Equipment used to apply cleaning materials to a substrate to prepare it for coating application (surface preparation) or to remove dried coating; to apply coating to a substrate (coating application) and to dry or cure the coating after the application; or to clean coating operation equipment (equipment cleaning). A single coating operation may include any

aq-12-01n • 4/30/15 Page 60

combination of these types of equipment, but always includes at least the point at which a given quantity of coating or cleaning material is applied to a given part and all subsequent points in the affected source where organic HAP are emitted from the specific quantity of coating or cleaning material on the specific part. There may be multiple coating operations in an affected source. Coating application with handheld, non-refillable aerosol containers, touch-up markers, or marking pens is not a coating operation for the purposes of 40 CFR pt. 63, subp. MMMM.

General use coating: Any material that meets the definition of coating but does not meet the definition of high performance coating, rubber-to-metal coating, magnet wire coating, or extreme performance fluoropolymer coating as defined in 40 CFR Section 63.3981.

High performance coating: Any coating applied to architectural subsections which is required to meet the specifications of Architectural Aluminum Manufacturer’s Association’s publication number AAMA 605.2-2000; Any coating applied to a substrate which during normal use must withstand temperatures of at least 538 degrees Celsius (1000 degrees Fahrenheit).

Magnet wire coatings (commonly referred to as magnet wire enamels): Coatings applied to a continuous strand of wire which will be used to make turns (windings) in electrical devices such as coils, transformers, or motors. Magnet wire coatings provide high dielectric strength and turn-to-turn conductor insulation. This allows the turns of an electrical device to be placed in close proximity to one another which leads to increased coil effectiveness and electrical efficiency.

Rubber-to-metal coatings: Coatings that contain heat-activated polymer systems in either solvent or water that, when applied to metal substrates, dry to a non-tacky surface and react chemically with the rubber and metal during a vulcanization process.

Extreme performance fluoropolymer coating: Coatings that are formulated systems based on fluoropolymer resins which often contain bonding matrix polymers dissolved in non-aqueous solvents as well as other ingredients. Once applied to a substrate, extreme performance fluoropolymer coatings undergo a curing process that typically requires high temperatures, a chemical reaction, or other specialized technology.


Based on the current and expected operations of the affected source, this permit only includes the compliant material option specified in 40 CFR Section 63.3891(a) and the emission rate without add-on controls option specified in 40 CFR Section 63.3891(b). If the Permittee later chooses to switch to or add the other compliance options allowed in the standard, the Permittee shall comply with all applicable portions of 40 CFR pt. 63, subp. MMMM for those options. In addition, the Permittee shall apply for an individual Part 70 permit prior to making this switch.

COMPLIANT MATERIAL OPTION REQUIREMENTS hdr

Compliant Material Option: The Permittee shall demonstrate that the organic HAP content of each coating used in the coating operation(s) is less than or equal to the applicable HAP emission limit(s), determined on a monthly basis; and that each thinner and/or other additive and cleaning material used contains no organic HAP. The Permittee shall meet all the requirements of 40 CFR Sections 63.3940, 63.3941, and 63.3942 to demonstrate compliance with the emission limit using this option.


Compliance Demonstration: For each compliance period, the Permittee shall use no coating for which the organic HAP content (determined according to the Organic HAP Content requirement below) exceeds the applicable organic HAP emission limit in this permit, and use no thinner and/or other additive, or cleaning material that contains organic HAP, determined according to the requirements below.

40 CFR Sections 63.3942(a) and 63.3941(e); Minn. R. 7011.8090

aq-12-01n • 4/30/15 Page 64

Facility-Specific Emission Limit (Alternative 2): If the Permittee has elected to comply with a facility-specific emission limit under 40 CFR Section 63.3890(c), the Permittee shall also perform the calculation using Equation M1 in Appendix B on a monthly basis using the data from the previous 12 months of operation.


To demonstrate compliance with the Compliant Materials option, the Permittee shall use the procedures in the Compliant Material Option Requirements section of this permit on each coating, thinner and/or other additive, and cleaning material in the condition it is in when it is received from its manufacturer or supplier and prior to any alteration.

The Permittee is not required to redetermine the organic HAP content of coatings, thinners and/or other additives, and cleaning materials that are reclaimed on-site (or reclaimed off-site if the Permittee has documentation showing that the Permittee received back the exact same materials that were sent off-site) and reused in the coating operation for which the Compliant Materials option is used, provided these materials in their condition as received were demonstrated to comply with the compliant material option.

40 CFR Section 63.3941; Minn. R. 7011.8090

Mass Fraction: The Permittee shall determine the mass fraction of organic HAP (pounds of organic HAP per pound of coating) for each coating, thinner and/or other additive, and cleaning material used during the compliance period by using one of the following options:

1) Method 311 (appendix A to 40 CFR pt. 63). The Permittee may use Method 311 for determining the mass fraction of organic HAP. To use Method 311, the Permittee shall:

- Count each organic HAP that is measured to be present at 0.1 percent by mass or more for Occupational Safety and Health Administration (OSHA)-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for other compounds.

- Express the mass fraction of each organic HAP counted as a value truncated to four places after the decimal point.

- Calculate the total mass fraction of organic HAP in the test material by adding up the individual organic HAP mass fractions and truncating the result to three places after the decimal point;

2) Method 24 (appendix A to 40 CFR pt. 60). For coatings, the Permittee may use Method 24 to determine the mass fraction of nonaqueous volatile matter and use that value as a substitute for mass fraction of organic HAP. For reactive adhesives in which some of the HAP react to form solids and are not emitted to the atmosphere, the Permittee may use the alternative method described in appendix A to 40 CFR pt. 63, subp. PPPP, rather than Method 24. The Permittee may use the volatile fraction that is emitted, as measured by the alternative method in appendix A to 40 CFR pt. 63, subp. PPPP, as a substitute for the mass fraction of organic HAP;


Continued below

aq-12-01n • 4/30/15 Page 65

3) Alternative Method. The Permittee may use an alternative test method for determining the mass fraction of organic HAP once the Administrator has approved it. The Permittee shall follow the procedure in 40 CFR Section 63.7(f) to submit an alternative test method for approval;

4) Information from the supplier or manufacturer of the material. The Permittee may rely on information other than that generated by items 1-3 above, such as manufacturer's formulation data, if it represents each organic HAP that is present in 0.1 percent by mass or more for OSHA-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for the other compounds. For reactive adhesives in which some of the HAP react to form solids and are not emitted to the atmosphere, the Permittee may rely on manufacturer's data that expressly states the organic HAP or volatile matter mass fraction emitted. If there is a disagreement between such information and the results of a test conducted according to items 1-3 above, then the test method results will take precedence unless, after consultation, the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct; or

5) Solvent blends. Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which must be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer's data for solvent blends are not available, The Permittee may use the default values for the mass fraction of organic HAP in these solvent blends listed in Table 3 or 4 of Appendix D.

If the tables are used, use the values in Table 3 for all solvent blends that match the Table 3 entries according to the instructions for Table 3. Table 4 may be used only if the solvent blends in the materials used do not match any of the solvent blends in Table 3 and it is known only whether the blend is aliphatic or aromatic. However, if the results of a Method 311 test indicate higher values than those listed in Tables 3 or 4, the Method 311 results will take precedence.

Volume Fraction: The Permittee shall determine the volume fraction of coating solids (gallons of coating solids per gallons of coating) for each coating used during the compliance period as specified below. If test results obtained according to item 1 below do not agree with the information obtained under items 3 or 4 below, the test results will take precedence.

1) ASTM Method D2697-86 (reapproved 1998) or ASTM Method D6093-97 (Reapproved 2003). The Permittee may use ASTM methods as specified in 40 CFR Section 63.3941(b)(1) to determine the volume fraction of coating solids for each coating. Divide the nonvolatile volume percent obtained with the methods by 100 to calculate volume fraction of coating solids;

Continued below

aq-12-01n • 4/30/15 Page 66

2) Alternative Method. The Permittee may use an alternative test method for determining the solids content of each coating once the Administrator has approved it. Follow the procedure in 40 CFR Section 63.7(f) to submit an alternative test method for approval;

3) Information from the supplier or manufacturer of the material. The Permittee may obtain the volume fraction of coating solids for each coating from the supplier or manufacturer; or

(4) Calculation of volume fraction of coating solids. The Permittee may determine the volume fraction of coating solids by using Equation MC1 in Appendix D.

Density: The Permittee shall determine the density of each coating used during the compliance period from test results using ASTM Method D1475-98, "Standard Test Method for Density of Liquid Coatings, Inks, and Related Products" (incorporated by reference, see 40 CFR 63.14), information from the supplier or manufacturer of the material, or specific gravity data for pure chemicals. If there is disagreement between ASTM Method D1475-98 test results and the supplier's or manufacturer's information, the test results will take precedence unless, after consultation, the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct.

40 CFR Sections 63.3941(c) and 63.3942(a); Minn. R. 7011.8090

Organic HAP Content: The Permittee shall calculate the organic HAP content, pounds of organic HAP emitted per gallon coating solids used, of each coating used during the compliance period using Equation MC2 in Appendix D.

40 CFR Sections 63.3941(d) and 63.3942(a); Minn. R. 7011.8090

Deviation: The use of any coating, thinner and/or other additive, or cleaning material that does not meet the criteria specified in 40 CFR Section 63.3942(a) is a deviation from the emission limitations. The Permittee shall report such a deviation as specified in 40 CFR Sections 63.3910(c)(6) and 63.3920(a)(5).

40 CFR Section 63.3942(b); Minn. R. 7011.8090

EMISSION RATE WITHOUT ADD-ON CONTROLS OPTION REQUIREMENTS hdr

Emission Rate without Add-on Controls Option: The Permittee shall demonstrate that, based on the coatings, thinners, and/or other additives, and cleaning materials used in the coating operation(s), the organic HAP emission rate for the coating operation(s) is less than or equal to the applicable HAP emission limit(s), calculated as a rolling 12-month emission rate and determined on a monthly basis. The Permittee shall meet all the requirements of 40 CFR Sections 63.3950, 63.3951, and 63.3952 to demonstrate compliance with the emission limit using this option.


Compliance Demonstration: For each compliance period, the organic HAP emission rate, determined according to the following requirements (40 CFR Section 63.3951(a) through (g)), shall be less than or equal to the applicable organic HAP emission limit for each subcategory in this permit or the predominant activity or facility-specific emission limit allowed in 40 CFR Section 63.3890(c).

To demonstrate compliance with the Emission Rate without Add-On Controls option, the Permittee shall use the procedures below on each coating, thinner and/or other additive, and cleaning material used in the coating operations for which the emission rate without add-on controls option is applied.

When calculating the organic HAP emission rate according to this section, the Permittee shall not include any coatings, thinners and/or other additives, or cleaning materials used on coating operations for which the Permittee uses the compliant material option

The Permittee is not required to redetermine the organic HAP content of coatings, thinners and/or other additives, and cleaning materials that are reclaimed on-site (or reclaimed off-site if the Permittee has documentation showing that the Permittee received back the exact same materials that were sent off-site) and reused in the coating operation for which the Emission Rate without Add-On Controls option is used.

If the affected source uses coatings, thinners and/or other additives, or cleaning materials that have been reclaimed on-site, in the calculations the Permittee may reduce the amount of each used in a month by the amount of each that is reclaimed.


Mass Fraction: By the 15th of the month, the Permittee shall determine the mass fraction of organic HAP (pounds of organic HAP per pound of coating) for each coating, thinner and/or other additive, and cleaning material used during the previous month by using one of the following options:

1) Method 311 (appendix A to 40 CFR pt. 63). The Permittee may use Method 311 for determining the mass fraction of organic HAP. To use Method 311, count each organic HAP that is measured to be present at 0.1 percent by mass fraction or more for Occupational Safety and Health Administration (OSHA)-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for other compounds. Express the mass fraction of each organic HAP counted as a value truncated to four places after the decimal point. Calculate the total mass fraction of organic HAP in the test material by adding up the individual organic HAP mass fractions and truncating the result to three places after the decimal point;

2) Method 24 (appendix A to 40 CFR pt. 60). For coatings, the Permittee may


Continued below

aq-12-01n • 4/30/15 Page 68

use Method 24 to determine the mass fraction of nonaqueous volatile matter and use that value as a substitute for mass fraction of organic HAP. For reactive adhesives in which some of the HAP react to form solids and are not emitted to the atmosphere, the Permittee may use the alternative method described in appendix A to 40 CFR pt. 63, subp. PPPP, rather than Method 24. The Permittee may use the volatile fraction that is emitted, as measured by the alternative method in appendix A to 40 CFR pt. 63, subp. PPPP, as a substitute for the mass fraction of organic HAP;

3) Alternative Method. The Permittee may use an alternative test method for determining the mass fraction of organic HAP once the Administrator has approved it. The Permittee must follow the procedure in 40 CFR Section 63.7(f) to submit an alternative test method for approval;

4) Information from the supplier or manufacturer of the material. The Permittee may rely on information other than that generated by items 1-3 above, such as manufacturer's formulation data, if it represents each organic HAP that is present in 0.1 percent by mass or more for OSHA-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for the other compounds. For reactive adhesives in which some of the HAP react to form solids and are not emitted to the atmosphere, the Permittee may rely on manufacturer's data that expressly states the organic HAP or volatile matter mass fraction emitted. If there is a disagreement between such information and the results of a test conducted according to items 1-3 above, then the test method results will take precedence unless, after consultation, the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct; or

5) Solvent blends. Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which must be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer's data for solvent blends are not available, The Permittee may use the default values for the mass fraction of organic HAP in these solvent blends listed in Table 3 or 4 of Appendix D.

If the tables are used, the Permittee shall use the values in Table 3 for all solvent blends that match the Table 3 entries according to the instructions for Table 3, and Table 4 may be used only if the solvent blends in the materials used do not match any of the solvent blends in Table 3 and it is known only whether the blend is aliphatic or aromatic. However, if the results of a Method 311 (appendix A to 40 CFR pt. 63) test indicate higher values than those listed in Tables 3 or 4, the Method 311 results will take precedence unless, after consultation, the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct.

Volume Fraction: By the 15th of the month, the Permittee shall determine the volume fraction of coating solids (gallons of coating solids per gallons of coating) for each coating used during the previous month as specified below. If test results obtained according to item 1 below do not agree with the


aq-12-01n • 4/30/15 Page 69

information obtained under items 3 or 4 below, the test results will take precedence unless, after consultation, the Permittee can demonstrate to the satisfaction of the Agency that the formulation data are correct.

1) ASTM Method D2697-86 (reapproved 1998) or ASTM Method D6093-97 (Reapproved 2003). The Permittee may use ASTM methods as specified in 40 CFR Section 63.3941(b)(1) to determine the volume fraction of coating solids for each coating. The Permittee shall divide the nonvolatile volume percent obtained with the methods by 100 to calculate volume fraction of coating solids;

2) Alternative Method. The Permittee may use an alternative test method for determining the solids content of each coating once the Administrator has approved it according to 40 CFR Section 63.7(f);


(4) Calculation of volume fraction of coating solids. The Permittee may determine the volume fraction of coating solids by using Equation MC1 in Appendix D.

Density of Each Material: By the 15th of the month, the Permittee shall determine the density of each liquid coating, thinner and/or additive, and cleaning material used during the previous month from test results using ASTM Method D1475-98, "Standard Test Method for Density of Liquid Coatings, Inks, and Related Products" (incorporated by reference, see 40 CFR 63.14), information from the supplier or manufacturer of the material, or reference sources providing density or specific gravity data for pure materials. If there is disagreement between ASTM Method D1475-98 or ASTM Method D5965-02 test results and other information sources, the test results will take precedence unless, after consultation, the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct.

If the Permittee includes powder coatings in this compliance determination option, the Permittee shall determine the density of powder coatings, using ASTM Method D5965-02, “Standard Test Methods for Specific Gravity of Coating Powers” (incorporated by reference, see 40 CFR 63.14), or information from the supplier.

If the Permittee purchases materials or monitors consumption by weight instead of volume, the Permittee is not required to determine material density. Instead, the Permittee may use the material weight in place of the combined terms for density and volume in Equations ME1a, ME1b, ME1c, and ME2 in Appendix D.


Volume of Each Material: By the 15th of the month, determine the volume (gallons) of each coating, thinner and/or other additive, and cleaning material used during the previous month by measurement or usage records.

If the Permittee purchases materials or monitors consumption by weight


aq-12-01n • 4/30/15 Page 70

instead of volume, the Permittee is not required to determine the volume of each material used. Instead, the Permittee may use the material weight in place of the combined terms for density and volume in Equations ME1a, ME1b, ME1c, and ME2 in Appendix D.

Organic HAP Emissions: The organic HAP emissions is the combined mass of organic HAP contained in all coatings, thinners and/or other additives, and cleaning materials used during the previous month minus the organic HAP in certain waste materials. By the 15th of the month, the Permittee shall calculate the mass of organic HAP emissions for the previous month, using Equation ME1 in Appendix D.

40 CFR Sections 63.3951(e) and 63.3952(a); Minn. R. 7011.8090

Total Volume Used: By the 15th of the month, the Permittee shall determine the total volume of coating solids used, gallons, which is the combined volume of coating solids for all the coatings used during the previous month, using Equation ME2 in Appendix D.

40 CFR Sections 63.3951(f) and 63.3952(a); Minn. R. 7011.8090

Organic HAP Emission Rate: By the 15th of the month, the Permittee shall calculate the organic HAP emission rate for the previous month and for the rolling compliance period (lb organic HAP emitted per gallon coating solids used) using Equation ME3 in Appendix D.

40 CFR Sections 63.3951(g) and 63.3952(a); Minn. R. 7011.8090

Deviation: If the organic HAP emission rate for any 12-month compliance period exceeds the applicable HAP emission limit, this is a deviation from the emission limitation for that compliance period. The Permittee shall report such a deviation as specified in 40 CFR Sections 63.3910(c)(6) and 63.3920(a)(6).

If the affected source also performs surface coating subject to any other subparts in 40 CFR pt. 63, the Permittee may choose for the affected source to comply with only one subpart. In order to choose this alternative, the total mass of organic HAP emissions from all surface coating operations in the affected source must be less than or equal to the total mass of organic HAP emissions that would result if the applicable subparts were complied with separately. The Permittee must make this comparison for the initial compliance period and report it in the Notification of Compliance Status as required in 40

40 CFR Section 63.4081(e); Minn. R. 7011.7900

aq-12-01n • 4/30/15 Page 80


CFR Section 63.4110(b)(10) and in the Notification of Compliance Status. If the Permittee chooses this alternative, then demonstration of compliance with the other subpart constitutes compliance with 40 CFR pt. 63, subp. NNNN.

HAP EMISSION LIMITS hdr

Existing affected source: Organic HAP emissions less than or equal to 1.10 pound per gallon of coating solids used during each compliance period.


New or reconstructed affected source: Organic HAP emissions less than or equal to 0.18 lb/gallon of coating solids used during each compliance period.








Compliance Options: The Permittee must include all coatings, thinners, and cleaning materials used in the affected source when determining the organic HAP emission rate. To make this determination the Permittee shall use either the compliant materials option or the emission rate without add-on controls option for every coating operation in the affected source

The Permittee may apply any of the compliance options to an individual coating operation, or to multiple coating operations as a group, or to the entire affected source. The Permittee may use different compliance options for different coating operations or at different times on the same coating operation.

However, the Permittee may not use different compliance options at the same time on the same coating operation. If the Permittee switches between compliance options for any coating operation or group of coating operations, the Permittee shall document this switch as required by 40 CFR Section 63.4131(c), and the Permittee shall report it in the next semiannual compliance report listed in Table B of this permit.


Compliance period: A compliance period consists of one month. Each month, after the end of the initial compliance period described in 40 CFR Sections 63.4140 and 63.4150, is the end of a compliance period.


The Permittee shall comply with the applicable emission limitations above, and shall always operate and maintain the affected source according to the

40 CFR Sections 63.4100(a)(1) and

General Provisions Appendix: This permit contains an appendix which lists the requirements of the general provisions in 40 CFR Sections 63.1 through 63.15, and shows which parts of the general provisions apply to sources subject to 40 CFR pt. 63, subp. NNNN.


40 CFR Section 63.4101, Table 2 to 40 CFR pt. 63, subp. NNNN; Minn. R. 7011.7900; Minn. R. 7007.0800, subp. 2


Compliant Material Option: The Permittee shall demonstrate that the organic HAP content of each coating used in the coating operation(s) is less than or equal to the applicable HAP emission limit(s), determined on a monthly basis; and that each thinner and/or cleaning material used contains no organic HAP. The Permittee shall meet all the requirements of 40 CFR Sections 63.4140, 63.4141, and 63.4142 to demonstrate compliance with the emission limit using this option.


Compliance Demonstration: By the 15th of each month for the previous 1-month compliance period, the Permittee shall use the calculated organic HAP content for each coating used during the previous month to demonstrate compliance with the following:

For each compliance period, the Permittee shall use no coating for which the organic HAP content (determined according to the Organic HAP Content requirement below) exceeds the applicable organic HAP emission limit in this permit, and use no thinner and/or cleaning material that contains organic HAP, determined according to the requirements below.


To demonstrate compliance with the Compliant Materials option, the Permittee shall use the procedures in the Compliant Material Option Requirements section of this permit on each coating, thinner, and cleaning material in the condition it is in when it is received from its manufacturer or supplier and prior to any alteration.

The Permittee is not required to redetermine the organic HAP content of cleaning materials that are reclaimed and reused on-site provided these materials in their condition as received were demonstrated to comply with the compliant material option.

If the Mass Fraction of organic HAP of a coating equals zero, and the Permittee uses the Compliant Material option, the Permittee is not required to determine the Volume Fraction or the Density for that coating.


Mass Fraction: The Permittee shall determine the mass fraction of organic HAP (pound of organic HAP per pound of coating) for each coating, thinner, and cleaning material used during the compliance period by using one of the following options:

1) Method 311 . The Permittee may use Method 311 for determining the mass fraction of organic HAP. To use Method 311, the Permittee shall:

- Count each organic HAP that is measured to be present at 0.1 percent by


aq-12-01n • 4/30/15 Page 83

mass or more for Occupational Safety and Health Administration (OSHA)-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP compounds.



2) Method 24. For coatings, the Permittee may use Method 24 to determine the mass fraction of nonaqueous volatile matter and use that value as a substitute for mass fraction of organic HAP;

3) Alternative Method. The Permittee may use an alternative test method for determining the mass fraction of organic HAP once the Administrator has approved it.;

4) Information from the supplier or manufacturer of the material. The Permittee may rely on information other than that generated by items 1-3 above, such as manufacturer's formulation data, if it represents each organic HAP that is present in 0.1 percent by mass or more for OSHA-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP compounds. If there is a disagreement between such information and the results of a test conducted according to items 1-3 above, then the test method results will take precedence unless, after consultation, the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct; or

5) Solvent blends. Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which must be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer's data for solvent blends are not available, The Permittee may use the default values for the mass fraction of organic HAP in these solvent blends listed in Table 3 or 4 of Appendix G. If the tables are used, the Permittee shall use the values in Table 3 for all solvent blends that match the Table 3 entries according to the instructions for Table 3, and Table 4 may be used only if the solvent blends in the materials used do not match any of the solvent blends in Table 3 and it is known only whether the blend is aliphatic or aromatic. However, if the results of a Method 311 test indicate higher values than those listed in Tables 3 or 4, the Method 311 results will take precedence.

Volume Fraction: The Permittee shall determine the volume fraction of coating solids (gallons of coating solids per gallons of coating) for each coating used during the compliance period as specified below.

1) Test Results: The Permittee may use ASTM Method D2697-86 (reapproved 1998) or ASTM Method D6093-97 (Reapproved 2003; both methods incorporated by reference, see 40 CFR Section 63.14). The Permittee shall


aq-12-01n • 4/30/15 Page 84

divide the nonvolatile volume percent obtained with the methods by 100 to calculate volume fraction of coating solids;

2) Information from the supplier or manufacturer of the material: The Permittee may obtain the volume fraction of coating solids for each coating from the supplier or manufacturer; or

3) Calculation of volume fraction of coating solids. The Permittee may determine the volume fraction of coating solids by using Equation NC1 in Appendix G.

If the Mass Fraction of organic HAP of a coating equals zero, determined according to the procedure above, and the Permittee uses the Compliant Material option, the Permittee is not required to determine the Volume Fraction for that coating.

Density: The Permittee shall determine the density of each coating used during the compliance period from test results using ASTM Method D1475-98, "Standard Test Method for Density of Liquid Coatings, Inks, and Related Products" (incorporated by reference, see 40 CFR 63.14), information from the supplier or manufacturer of the material, or reference sources providing density or specific gravity data for pure chemicals. If there is disagreement between ASTM Method D1475-98 test results and the supplier's or manufacturer's information, the test results will take precedence.

If the Mass Fraction of organic HAP of a coating equals zero, determined according to the procedure above, and the Permittee uses the Compliant Material option, the Permittee is not required to determine Density for that coating.


Organic HAP Content: The Permittee shall calculate the organic HAP content, in pound of organic HAP per gallon coating solids used, of each coating used during the compliance period using Equation NC2 in Appendix G.

If the mass fraction of organic HAP equals zero, then the organic HAP content also equals zero and the Permittee is not required to use Equation NC2 to calculate the organic HAP content.


Deviation: The use of any coating, thinner, or cleaning material that does not meet the criteria specified in 40 CFR Section 63.4142(a) is a deviation from the emission limitations. The Permittee shall report such a deviation as specified below in the REPORTING AND SUBMITTALS section.



Emission Rate without Add-on Controls Option: The Permittee shall demonstrate that, based on the coatings, thinners, and cleaning materials used in the coating operation(s), the organic HAP emission rate for the coating operation(s) is less than or equal to the applicable HAP emission limit(s) for each compliance period. The Permittee shall meet all the requirements of 40 CFR Sections 63.4150, 63.4151, and 63.4152 to demonstrate compliance with the emission limit using this option.


aq-12-01n • 4/30/15 Page 85

Compliance Demonstration: By the 15th of each month for the previous month the Permittee shall perform the calculations in the Emission Rate without Add-on Controls Option Requirements section of this permit using data from the previous month of operation to demonstrate compliance with the following:

For each compliance period, the organic HAP emission rate shall be less than or equal to the applicable organic HAP emission limit in this permit.


To demonstrate compliance with the Emission Rate without Add-On Controls option, the Permittee shall use the procedures below on each coating, thinner, and cleaning material used in the coating operations for which the Emission Rate without Add-On Controls option is applied.

When calculating the organic HAP emission rate according to this section, the Permittee shall not include any coatings, thinners, or cleaning materials used on coating operations for which the Permittee uses the Compliant Material option.

The Permittee is not required to redetermine the organic HAP content of coatings, thinners, and cleaning materials that are reclaimed on-site and reused in the coating operation for which the Emission Rate without Add-On Controls option is used.


Mass Fraction: By the 15th of the month, the Permittee shall determine the mass fraction of organic HAP (pounds of organic HAP per pound of coating) for each coating, thinner, and cleaning material used during the previous month by using one of the following options:

1) Method 311 (appendix A to 40 CFR pt. 63). The Permittee may use Method 311 for determining the mass fraction of organic HAP. To use Method 311 the Permittee shall:

- Count each organic HAP that is measured to be present at 0.1 percent by mass or more for OSHA-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP compounds.



2) Method 24 (appendix A to 40 CFR pt. 60). For coatings, the Permittee may use Method 24 to determine the mass fraction of nonaqueous volatile matter and use that value as a substitute for mass fraction of organic HAP.

3) Alternative Method. The Permittee may use an alternative test method for determining the mass fraction of organic HAP once the Administrator has approved it. The Permittee must follow the procedure in 40 CFR Section 63.7(f) to submit an alternative test method for approval;

4) Information from the supplier or manufacturer of the material. The


Continued below

aq-12-01n • 4/30/15 Page 86

Permittee may rely on information other than that generated by items 1-3 above, such as manufacturer's formulation data, if it represents each organic HAP that is present in 0.1 percent by mass or more for OSHA-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for the other compounds. If there is a disagreement between such information and the results of a test conducted according to items 1-3 above, then the test method results will take precedence; or

5) Solvent blends. Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which must be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer's data for solvent blends are not available, The Permittee may use the default values for the mass fraction of organic HAP in these solvent blends listed in Table 3 or 4 of Appendix G. If the tables are used, the Permittee shall use the values in Table 3 for all solvent blends that match the Table 3 entries according to the instructions for Table 3, and Table 4 may be used only if the solvent blends in the materials used do not match any of the solvent blends in Table 3 and it is known only whether the blend is aliphatic or aromatic. However, if the results of a Method 311 (appendix A to 40 CFR pt. 63) test indicate higher values than those listed in Tables 3 or 4, the Method 311 results will take precedence.

Volume Fraction: By the 15th of the month, the Permittee shall determine the volume fraction of coating solids (gallons of coating solids per gallons of coating) for each coating used during the previous month as specified below.

1) ASTM Method D2697-86 (reapproved 1998) or ASTM Method D6093-97 (Reapproved 2003). The Permittee may use ASTM methods as specified in 40 CFR Section 63.4141(b)(1) to determine the volume fraction of coating solids for each coating. The Permittee shall divide the nonvolatile volume percent obtained with the methods by 100 to calculate volume fraction of coating solids;


3) Calculation of volume fraction of coating solids. The Permittee may determine the volume fraction of coating solids by using Equation NC1 in Appendix G.


Density: By the 15th of the month, the Permittee shall determine the density of each coating used during the compliance period from test results using ASTM Method D1475-98, "Standard Test Method for Density of Liquid Coatings, Inks, and Related Products" (incorporated by reference, see 40 CFR 63.14), information from the supplier or manufacturer of the material, or reference sources providing density or specific gravity data for pure chemicals. If there is disagreement between ASTM Method D1475-98 test results and the supplier's or manufacturer's information, the test results will take precedence.

Alternative 1 – Facilities with surface coating operations that are predominantly either general use or TPO:

If the general use or TPO surface coating operations subject to only one of the emission limits specified in 40 CFR Section 63.4490(a)(1), (b)(3), (b)(1), or (b)(3) account for 90 percent or more of the surface coating activity at the facility then compliance with that emission limitation for all surface coating operations constitutes compliance with the other applicable emission limits. Refer to Appendix E for determining eligibility to use Alternative 1 to demonstrate compliance with the applicable emission limits.


Continued below

aq-12-01n • 4/30/15 Page 96

Alternative 2 – Facility-specific emission limit:

The Permittee shall calculate and comply with a facility-specific emission limit as described in Appendix E. If the Permittee elects to comply using the facility-specific emission limit (Alternative 2), then compliance with the facility-specific emission limit and the emission limitations in 40 CFR pt. 63, subp. PPPP for all surface coating operations constitutes compliance with this and other applicable surface coating NESHAP.







Compliance Options: The Permittee shall include all coatings (as defined in 40 CFR Section 63.4581), thinners and/or other additives, and cleaning materials used in the affected source when determining whether the organic HAP emission rate is equal to or less than the applicable emission limit above. To make this determination, the Permittee shall use at least one of these two compliance options: compliant material option or emission rate without add-on controls option.

The Permittee shall use either the compliant materials option or the emission rate without add-on controls option for every coating operation in the affected source.

The Permittee may apply any of the compliance options to an individual coating operation, or to multiple coating operations as a group, or to the entire affected source. The Permittee may use different compliance options for different coating operations or at different times on the same coating operation. The Permittee may employ different compliance options when different coatings are applied to the same part, or when the same coating is applied to different parts.



The Permittee shall conduct a separate initial compliance demonstration for each general use coating, TPO coating, automotive lamp coating, and assembled on-road vehicle coating affected source unless the Permittee has elected to comply with a predominant activity (Alternative 1) or facility-specific

40 CFR Sections 63.4541, and 63.4551; Minn. R. 7011.8130

aq-12-01n • 4/30/15 Page 97

emission limit (Alternative 2) as provided in 40 CFR Section 63.4490(c).

If the Permittee has elected to comply with one of these emission limit alternatives, the Permittee shall demonstrate that all coating operations included in the predominant activity determination or calculation of the facility-specific emission limit comply with that limit.

The Permittee shall comply with the emission limitations as specified below:

1) Any coating operation(s) for which the Permittee uses the compliant material option or the emission rate without add-on controls option, as specified in 40 CFR Section 63.4491(a) and (b), shall be in compliance with the HAP emission limit at all times.

2) The Permittee shall always operate and maintain the affected source according to the provisions in 40 CFR Section 63.6(e)(1)(i).

40 CFR Section 63.4500(a)(1) and (b); Minn. R. 7011.8130

A compliance period consists of 12 months. Each month, after the end of the initial compliance period described in 40 CFR Sections 63.4540 and 63.4550, is the end of a compliance period consisting of that month and the preceding 11 months.

The initial compliance period described in 40 CFR Sections 63.4540 and 63.4550 has passed. The Permittee shall continue to use the subsequent compliance periods as described above.


General Provisions Appendix: This permit contains an appendix which lists the requirements of the general provisions in 40 CFR Sections 63.1 through 63.15, and shows which parts of the general provisions apply to sources subject to 40 CFR pt. 63, subp. PPPP.


40 CFR Section 63.4501, Table 2 to 40 CFR pt. 63, subp. PPPP; Minn. R. 7011.8130; Minn. R. 7007.0800, subp. 2


Compliant Material Option: The Permittee shall demonstrate that the organic HAP content of each coating used in the coating operation(s) is less than or equal to the applicable HAP emission limit(s), and determined on a monthly basis; and that each thinner and/or other additive and cleaning material used contains no organic HAP. The Permittee shall meet all the requirements of 40 CFR Sections 63.4540, 63.4541, and 63.4542 to demonstrate compliance with the emission limit using this option.


Compliance Demonstration: For each compliance period, the Permittee shall use no coating for which the organic HAP content (determined according to the Organic HAP Content requirement below) exceeds the applicable organic HAP emission limit in this permit, and use no thinner and/or other additive, or cleaning material that contains organic HAP, determined according to the requirements below.


Facility-Specific Emission Limit (Alternative 2): If the Permittee has elected to comply with a facility-specific emission limit under 40 CFR Section 63.4490(c), the Permittee shall also perform the calculation using Equation M1 in Appendix

40 CFR Section 63.4542(a); Minn. R.

aq-12-01n • 4/30/15 Page 98

E on a monthly basis using the data from the previous 12 months of operation. 7011.8130

To demonstrate compliance with the Compliant Materials option, the Permittee shall use the procedures in the Compliant Material Option Requirements section of this permit on each coating, thinner and/or other additive, and cleaning material as received from its manufacturer or supplier.

The Permittee is not required to redetermine the organic HAP content of coatings, thinners and/or other additives, and cleaning materials that are reclaimed on-site (or reclaimed off-site if the Permittee has documentation showing that the Permittee received back the exact same materials that were sent off-site) and reused in the coating operation for which the Compliant Materials option is used, provided these materials in their condition as received were demonstrated to comply with the compliant material option.


Mass Fraction of Organic HAP: The Permittee shall determine the mass fraction of organic HAP (pounds of organic HAP per pound of coating) for each coating, thinner and/or other additive, and cleaning material used during the compliance period by using one of the following options:







4) Information from the supplier or manufacturer of the material. The


Continued below

aq-12-01n • 4/30/15 Page 99

Permittee may rely on information other than that generated by items 1-3 above, such as manufacturer's formulation data, if it represents each organic HAP that is present in 0.1 percent by mass or more for OSHA-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for the other compounds. For reactive adhesives in which some of the HAP react to form solids and are not emitted to the atmosphere, the Permittee may rely on manufacturer's data that expressly states the organic HAP or volatile matter mass fraction emitted. If there is a disagreement between such information and the results of a test conducted according to items 1-3 above, then the test method results will take precedence unless, after consultation, the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct; or

5) Solvent blends. Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which must be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer's data for solvent blends are not available, The Permittee may use the default values for the mass fraction of organic HAP in these solvent blends listed in Table 3 or 4 of Appendix E.


Mass Fraction of Coating Solids: The Permittee shall determine the mass fraction of coating solids (pounds of coating solids per pounds of coating) for each coating used during the compliance period by using one of the following options:

1) Method D2697-86 (appendix A to 40 CFR part 60). The Permittee shall use Method 24 for determining the mass fraction of coating solids. For reactive adhesives in which some of the liquid fraction reacts to form solids, the Permittee may use the alternative method contained in appendix A to 40 CFR pt. 63, subp. PPPP, rather than Method 24, to determine the mass fraction of coating solids.

2) Alternative Method. The Permittee may use an alternative test method for determining the solids content of each coating once the Administrator has approved it. The Permittee shall follow the procedure in 40 CFR Section 63.7(f) to submit an alternative test method for approval; or

3) Information from the supplier or manufacturer of the material. The Permittee may obtain the mass fraction of coating solids for each coating


aq-12-01n • 4/30/15 Page 100

from the supplier or manufacturer. If there is disagreement between such information and the test method results, then the test method results will take precedence unless, after consultation the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct.

Organic HAP Content: The Permittee shall calculate the organic HAP content, pounds of organic HAP emitted per pound coating solids used, of each coating used during the compliance period using Equation PC1 in Appendix E.


Deviation: The use of any coating, thinner and/or other additive, or cleaning material that does not meet the criteria specified in 40 CFR Section 63.4542(a) is a deviation from the emission limitations. The Permittee shall report such a deviation as specified in 40 CFR Sections 63.4510(c)(6) and 63.4520(a)(5).



Emission Rate without Add-on Controls Option: The Permittee shall demonstrate that, based on the coatings, thinners, and/or other additives, and cleaning materials used in the coating operation(s), the organic HAP emission rate for the coating operation(s) is less than or equal to the applicable HAP emission limit(s), calculated as a rolling 12-month emission rate and determined on a monthly basis. The Permittee shall meet all the requirements of 40 CFR Sections 63.4550, 63.4551, and 63.4552 to demonstrate compliance with the emission limit using this option.


Compliance Demonstration: For each compliance period, the organic HAP emission rate, determined according to the following requirements (40 CFR Section 63.4551(a) through (g)), shall be less than or equal to the applicable organic HAP emission limit for each subcategory in this permit or the predominant activity or facility-specific emission limit allowed in 40 CFR Section 63.4490(c).

The Permittee shall perform the calculations in the Emission Rate without Add-on Controls Option Requirements section of this permit on a monthly basis (by the 15th of the month for the previous month) using data from the previous 12 months of operation.


Facility-Specific Emission Limit (Alternative 2): If the Permittee has elected to comply with a facility-specific emission limit under 40 CFR Section 63.4490(c), the Permittee shall also perform the calculation using Equation P1 in Appendix E on a monthly basis (by the 15th of the month for the previous month) using the data from the previous 12 months of operation.


To demonstrate compliance with the Emission Rate without Add-On Controls option, the Permittee shall use the procedures below on each coating, thinner and/or other additive, and cleaning material used in the coating operations for which the emission rate without add-on controls option is used.

When calculating the organic HAP emission rate according to this section, the Permittee shall not include any coatings, thinners and/or other additives, or cleaning materials used on coating operations for which the Permittee uses the


aq-12-01n • 4/30/15 Page 101

compliant material option.

The Permittee is not required to redetermine the organic HAP content of coatings, thinners and/or other additives, and cleaning materials that are reclaimed on-site (or reclaimed off-site if the Permittee has documentation showing that the Permittee received back the exact same materials that were sent off-site) and reused in the coating operation for which the Emission Rate without Add-On Controls option is used.

If the affected source uses coatings, thinners and/or other additives, or cleaning materials that have been reclaimed on-site, in the calculations the Permittee may reduce the amount of each used in a month by the amount of each that is reclaimed.

Mass Fraction of Organic HAP: By the 15th of the month, the Permittee shall determine the mass fraction of organic HAP (pounds of organic HAP per pound of coating) for each coating, thinner and/or other additive, and cleaning material used during the previous month by using one of the following options:







4) Information from the supplier or manufacturer of the material. The Permittee may rely on information other than that generated by items 1-3 above, such as manufacturer's formulation data, if it represents each


Continued below

aq-12-01n • 4/30/15 Page 102

organic HAP that is present in 0.1 percent by mass or more for OSHA-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for the other compounds. For reactive adhesives in which some of the HAP react to form solids and are not emitted to the atmosphere, the Permittee may rely on manufacturer's data that expressly states the organic HAP or volatile matter mass fraction emitted. If there is a disagreement between such information and the results of a test conducted according to items 1-3 above, then the test method results will take precedence unless, after consultation, the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct; or

5) Solvent blends. Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which must be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer's data for solvent blends are not available, The Permittee may use the default values for the mass fraction of organic HAP in these solvent blends listed in Table 3 or 4 of Appendix E.


Mass Fraction of Coating Solids: By the 15th of the month, the Permittee shall determine the mass fraction of coating solids (pounds of coating solids per pounds of coating) for each coating used during the previous month by using one of the following options:

1) Method D2697-86 (appendix A to 40 CFR part 60). The Permittee shall use Method 24 for determining the mass fraction of coating solids. For reactive adhesives in which some of the liquid fraction reacts to form solids, the Permittee may use the alternative method contained in appendix A to 40 CFR pt. 63, subp. PPPP, rather than Method 24, to determine the mass fraction of coating solids.

2) Alternative Method. The Permittee may use an alternative test method for determining the solids content of each coating once the Administrator has approved it. The Permittee shall follow the procedure in 40 CFR Section 63.7(f) to submit an alternative test method for approval; or

3) Information from the supplier or manufacturer of the material. The Permittee may obtain the mass fraction of coating solids for each coating from the supplier or manufacturer. If there is disagreement between such information and the test method results, then the test method results will


aq-12-01n • 4/30/15 Page 103

take precedence unless, after consultation the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct.

Density of Each Material: By the 15th of the month, the Permittee shall determine the density of each liquid coating, thinner and/or additive, and cleaning material used during the previous month from test results using ASTM Method D1475-98, "Standard Test Method for Density of Liquid Coatings, Inks, and Related Products" (incorporated by reference, see 40 CFR Section 63.14), information from the supplier or manufacturer of the material, or reference sources providing density or specific gravity data for pure materials. If there is disagreement between ASTM Method D1475-98 and other such information sources, the test results will take precedence unless, after consultation, the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct.

If the Permittee purchases materials or monitors consumption by weight instead of volume, the Permittee is not required to determine material density. Instead, the Permittee may use the material weight in place of the combined terms for density and volume in Equations PE1a, PE1b, PE1c, and PE2 in Appendix E.


Volume of Each Material: By the 15th of the month, the Permittee shall determine the volume (gallons) of each coating, thinner and/or other additive, and cleaning material used during the previous month by measurement or usage records.

If the Permittee purchases materials or monitors consumption by weight instead of volume, the Permittee is not required to determine the volume of each material used. Instead, the Permittee may use the material weight in place of the combined terms for density and volume in Equations PE1a, PE1b, PE1c, and PE2 in Appendix E.


Mass of Organic HAP Emissions: The mass of organic HAP emissions is the combined mass of organic HAP contained in all coatings, thinners and/or other additives, and cleaning materials used during each month minus the organic HAP in certain waste materials. By the 15th of the month, the Permittee shall calculate the mass of organic HAP emissions for the previous month, using Equation PE1 in Appendix E.


Total Mass of Coating Solids: By the 15th of the month, the Permittee shall determine the total mass of coating solids used, lb-mass, which is the combined mass of coating solids for all the coatings used during the previous month, using Equation PE2 in Appendix E.


Organic HAP Emission Rate: By the 15th of the month, the Permittee shall calculate the organic HAP emission rate for the previous month and for the rolling compliance period (lb organic HAP emitted per lb coating solids used) using Equation PE3 in Appendix E.


Deviation: If the organic HAP emission rate for any 12-month compliance period exceeds the applicable HAP emission limit, this is a deviation from the emission limitation for that compliance period. The Permittee shall report such

40 CFR Section 63.4552(b); Minn. R.

General Provisions Appendix: This permit contains an appendix which lists the requirements of the general provisions in 40 CFR Sections 63.1 through 63.15, and shows which parts of the general provisions apply to sources subject to 40 CFR pt. 63, subp. QQQQ.


40 CFR Section 63.4701, Table 4 to 40 CFR pt. 63, subp. QQQQ; Minn. R. 7011.8000; Minn. R. 7007.0800, subp. 2


Compliant Material Option: The Permittee shall demonstrate that the organic HAP content of each coating used in the coating operation(s) is less than or equal to the applicable HAP emission limit(s), determined on a monthly basis; and that each thinner and cleaning material used contains no organic HAP. The Permittee shall meet all the requirements of 40 CFR Sections 63.4740, 63.4741, and 63.4142 to demonstrate compliance with the emission limit using this option.



For each compliance period, the Permittee shall use no coating for which the organic HAP content (determined according to the Organic HAP Content requirement below) exceeds the applicable organic HAP emission limit in this permit, and use no thinner or cleaning material that contains organic HAP, determined according to the requirements below.


To demonstrate compliance with the Compliant Materials option, the Permittee shall use the procedures in the Compliant Material Option Requirements section of this permit on each coating, thinner, and cleaning material in the condition it is in when it is received from its manufacturer or supplier and prior to any alteration.

The Permittee is not required to redetermine the organic HAP content of coatings, thinners, and cleaning materials that are reclaimed and reused on-site provided these materials in their condition as received were demonstrated to comply with the compliant material option.

If the Mass Fraction of organic HAP of a coating equals zero, determined according to the procedure below, and the Permittee uses the Compliant Material option, the Permittee is not required to determine the Volume Fraction or the Density for that coating.


Mass Fraction: The Permittee shall determine the mass fraction of organic HAP (pounds of organic HAP per pounds of coating) for each coating, thinner, and cleaning material used during the compliance period by using one of the

40 CFR Sections 63.4741(a) and 63.4742(a); Minn. R.

aq-12-01n • 4/30/15 Page 116


following options:


- Count each organic HAP that is measured to be present at 0.1 percent by mass or more for Occupational Safety and Health Administration (OSHA)-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP compounds.


- Calculate the total mass fraction of organic HAP in the test material by adding up the individual organic HAP mass fractions and truncating the result to three places after the decimal point.

- If these values cannot be determined using Method 311, the owner or operator shall submit an alternative technique for determining their values for approval by the Administrator;

2) Method 24 (appendix A to 40 CFR pt. 60). For coatings, the Permittee may use Method 24 to determine the mass fraction of nonaqueous volatile matter and use that value as a substitute for mass fraction of organic HAP (Note: Method 24 is not appropriate for those coatings with a water content that would result in an effective detection limit greater than the applicable emission limit);



5) Solvent blends. Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which must be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer's data for solvent blends are not available, The Permittee may use the default values for the mass fraction of organic HAP in these

7011.8000

Continued below

1) Method 311 (appendix A to 40 CFR pt. 63). The Permittee may use Method 311 for determining the mass fraction of organic HAP. The Permittee shall:

- Count each organic HAP that is measured to be present at 0.1 percent by mass or more for Occupational Safety and Health Administration (OSHA)-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP compounds.


- Calculate the total mass fraction of organic HAP in the test material by adding up the individual organic HAP mass fractions and truncating the result to three places after the decimal point.

- If these values cannot be determined using Method 311, the owner or operator shall submit an alternative technique for determining their values for approval by the Administrator;

2) Method 24 (appendix A to 40 CFR pt. 60). For coatings, the Permittee may use Method 24 to determine the mass fraction of nonaqueous volatile matter and use that value as a substitute for mass fraction of organic HAP (Note: Method 24 is not appropriate for those coatings with a water content that would result in an effective detection limit greater than the applicable emission limit);

5) Solvent blends. Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which must be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer's data for solvent blends are not available, The Permittee may use the default values for the mass fraction of organic HAP in these solvent blends listed in Tables 5 or 6 of Appendix H. If the tables are used, the Permittee shall use the values in Table 5 for all solvent blends that match the Table 5 entries according to the instructions for Table 5, and Table 6 may be used only if the solvent blends in the materials used do not match any of the solvent blends in Table 5 and it is known only whether the blend is aliphatic or aromatic. However, if the results of a Method 311 (appendix A to 40 CFR pt. 63) test indicate higher values than those listed in Tables 5 or 6, the Method 311 results will take precedence.

Volume Fraction: The Permittee shall determine the volume fraction of coating solids (pounds of coating solids per pounds of coating) for each coating used during the compliance period as specified below.

1) ASTM Method D2697-86 or ASTM Method D6093-97. The Permittee may use ASTM methods as specified in 40 CFR Section 63.4141(b)(1) to determine the volume fraction of coating solids for each coating. The Permittee shall divide the nonvolatile volume percent obtained with the methods by 100 to calculate volume fraction of coating solids;

aq-12-01n • 4/30/15 Page 131


For each compliance period, the Permittee shall use no coating for which the organic HAP content (determined according to the Organic HAP Content requirement below) exceeds the applicable organic HAP emission limit in this permit, and use no thinner, or cleaning material that contains organic HAP, determined according to the requirements below.To demonstrate compliance with the Compliant Materials option, the Permittee shall use the procedures in the Compliant Material Option Requirements section of this permit on each coating, thinner, and cleaning material in the condition it is in when it is received from its manufacturer or supplier and prior to any alteration.

The Permittee is not required to redetermine the organic HAP content of cleaning materials that are reclaimed and reused on-site provided these materials in their condition as received were demonstrated to comply with the compliant material option.


Mass Fraction: The Permittee shall determine the mass fraction of organic HAP (pounds of organic HAP per pound of coating) for each coating, thinner, and cleaning material used during the compliance period by using one of the following options:

1) Method 311 (appendix A to 40 CFR pt. 63). The Permittee may use Method 311 for determining the mass fraction of organic HAP. To use Method 311, the Permittee shall:- Count each organic HAP that is measured to be present at 0.1 percent by




2) Method 24 (appendix A to 40 CFR pt. 60). For coatings, the Permittee may use Method 24 to determine the mass fraction of nonaqueous volatile matter and use that value as a substitute for mass fraction of organic HAP;


4) Information from the supplier or manufacturer of the material. The Permittee may rely on information other than that generated by items 1-3 above, such as manufacturer's formulation data, if it represents each organic HAP that is present in 0.1 percent by mass or more for OSHA-


Continued below

aq-12-01n • 4/30/15 Page 132


defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP compounds. If there is a disagreement between such information and the results of a test conducted according to items 1-3 above, then the test method results will take precedence unless, after consultation, the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct; or

5) Solvent blends. Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which must be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer's data for solvent blends are not available, The Permittee may use the default values for the mass fraction of organic HAP in these solvent blends listed in Table 3 or 4 of Appendix I. If the tables are used, the Permittee shall use the values in Table 3 for all solvent blends that match the Table 3 entries according to the instructions for Table 3, and Table 4 may be used only if the solvent blends in the materials used do not match any of the solvent blends in Table 3 and it is known only whether the blend is aliphatic or aromatic. However, if the results of a Method 311 (appendix A to 40 CFR pt. 63) test indicate higher values than those listed in Tables 3 or 4, the Method 311 results will take precedence.


1) Test Results: The Permittee may use ASTM Method D2697-86 (reapproved 1998) or ASTM Method D6093-97 (both incorporated by reference, see 40 CFR Section 63.14) to determine the volume fraction of coating solids for each coating. The Permittee shall divide the nonvolatile volume percent obtained with the methods by 100 to calculate volume fraction of coating solids. Alternatively, the Permittee may use another test method once the Permittee has obtained approval from the Administrator according to the requirement of 40 CFR Section 63.7(f)


3) Calculation of volume fraction of coating solids: If the volume fraction of coating solids cannot be determined using the options above, the Permittee may use Equation RC1 in Appendix I.

If there is disagreement between


aq-12-01n • 4/30/15 Page 133


ASTM Method D1475-90 test results and the supplier's or manufacturer's information, the test results will take precedence.

Organic HAP Content: The Permittee shall calculate the organic HAP content, in pounds of organic HAP per gallon coating solids, of each coating used during the compliance period using Equation RC2 in Appendix I.

If the mass fraction of organic HAP equals zero, then the organic HAP content also equals zero and the Permittee is not required to use Equation MC2 to calculate the organic HAP content.


Deviation: The use of any coating, thinner, or cleaning material that does not meet the criteria specified in 40 CFR Section 63.4941(e) is a deviation from the emission limitations. The Permittee shall report such a deviation as specified below in the REPORTING AND SUBMITTALS section.



Emission Rate without Add-on Controls Option: The Permittee shall demonstrate that, based on the coatings, thinners, and cleaning materials used in the coating operation or group of coating operations, the organic HAP emission rate for the coating operation(s) is less than or equal to the applicable HAP emission limit for each compliance period. The Permittee shall meet all the requirements of 40 CFR Sections 63.4950, 63.4951, and 63.4952 to demonstrate compliance with the emission limit using this option.


Compliance Demonstration: By the 15th of each month for the previous month the Permittee shall perform the calculations in the Emission Rate without Add-on Controls Option Requirements section of this permit using data from the previous month of operation to demonstrate compliance with the following:

For each compliance period, the organic HAP emission rate shall be less than or equal to the applicable organic HAP emission limit in this permit.


To demonstrate compliance with the Emission Rate without Add-On Controls option, use the procedures below on each coating, thinner, and cleaning material used in the coating operations or group of coating operations for which the Emission Rate without Add-On Controls option is applied.

When calculating the organic HAP emission rate according to this section, the Permittee shall not include any coatings, thinners, or cleaning materials used on coating operations for which the Permittee uses the Compliant Material option.

The Permittee is not required to redetermine the organic HAP content of coatings, thinners, and cleaning materials that are reclaimed on-site and reused in the coating operation for which the Emission Rate without Add-On Controls option is used.


Mass Fraction: By the 15th of the month, the Permittee shall determine the 40 CFR Sections

aq-12-01n • 4/30/15 Page 134


mass fraction of organic HAP (pounds of organic HAP per pound of coating) for each coating, thinner, and cleaning material used during the previous month by using one of the following options:

1) Method 311 (appendix A to 40 CFR pt. 63). To use Method 311 for determining the mass fraction of organic HAP, the Permittee shall:- Count each organic HAP that is measured to be present at 0.1 percent by




2) Method 24 (appendix A to 40 CFR pt. 60). For coatings, the Permittee may use Method 24 to determine the mass fraction of nonaqueous volatile matter and use that value as a substitute for mass fraction of organic HAP;

3) Alternative Method. The Permittee may use an alternative test method for determining the mass fraction of organic HAP once the Administrator has approved it in accordance with the procedure in 40 CFR Section 63.7(f);

4) Information from the supplier or manufacturer. The Permittee may rely on information such as manufacturer's formulation data, if it represents each organic HAP that is present in 0.1 percent by mass or more for OSHA-defined carcinogens as specified in 29 CFR Section 1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP compounds. If there is a disagreement between such information and the results of a test conducted according to items 1-3 above, then the test method results will take precedence unless, after consultation, the Permittee demonstrates to the satisfaction of the MPCA that the formulation data are correct; or

5) Solvent blends. Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which must be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer's data for solvent blends are not available, The Permittee may use the default values for the mass fraction of organic HAP in these solvent blends listed in Table 3 or 4 of Appendix I. If the tables are used, use the values in Table 3 for all solvent blends that match the Table 3 entries according to the instructions, and Table 4 may be used only if the solvent blends in the materials used do not match any of the solvent blends in Table 3 and it is known only whether the blend is aliphatic or aromatic. However, if the results of a Method 311 (appendix A to 40 CFR pt. 63) test indicate higher values than those listed in Tables 3 or 4, the test

1) Test Results: ASTM Method D2697-86 or ASTM Method D6093-97. The Permittee may use ASTM methods as specified in 40 CFR Section 63.4141(b)(1) to determine the volume fraction of coating solids for each coating. Divide the nonvolatile volume percent by 100 to calculate volume fraction of coating solids. Alternatively, the Permittee may use another test method once the Permittee has obtained approval from the Administrator according to 40 CFR Section 63.7(f).


3) Calculation of volume fraction of coating solids: If the volume fraction of coating solids cannot be determined using the options above, the Permittee must use Equation RC1 in Appendix I.


Density: By the 15th of the month, the Permittee shall determine the density of each coating used during the compliance period from test results using ASTM Method D1475-90 or information from the supplier or manufacturer of the material. If there is disagreement between ASTM Method D1475-90 test results and the supplier's or manufacturer's information, the test results will take precedence.


Volume: By the 15th of the month, the Permittee shall determine the volume (gallons) of each coating, thinner, and cleaning material used during the previous month by measurement or usage records.


Organic HAP Emissions: The organic HAP emissions is the combined mass of organic HAP contained in all coatings, thinners, and cleaning materials used during the previous month minus the organic HAP in certain waste materials.

STANDARD FOR VOLATILE ORGANIC COMPOUNDS (VOC) hdr

Limit: VOC emissions less than or equal to 0.90 kilogram of VOC per liter of coating solids applied for each calendar month.


PERFORMANCE TESTS AND COMPLIANCE PROVISIONS hdr

The Permittee shall conduct an initial performance test and a performance test each calendar month thereafter, according to the procedures below. Each monthly calculation is considered a performance test.

40 CFR Section 60.313(b); 40 CFR Section 60.8(a);Minn. R. 7011.2550

By the 15th of the month following the initial performance test, the Permittee shall use the following procedures for determining monthly volume-weighted average emissions of VOC's in kilograms per liter of coating solids applied (G), using data from the previous month of coating usage.


The Permittee shall determine the composition of the coatings by formulation data supplied by the manufacturer of the coating or by an analysis of each coating, as received, using Method 24.

The Permittee shall determine the volume of coating and the mass of VOC-solvent used for thinning purposes from company records on a monthly basis. If a common coating distribution system serves more than one affected facility or serves both affected and existing facilities, the Permittee shall estimate the volume of coating used at each facility by using the average dry weight of coating and the surface area coated by each affected and existing facility or by other procedures acceptable to the Administrator.

Calculation of VOCs emitted per unit coating solids applied: Calculate the volume-weighted average of the total mass of VOCs emitted per unit volume of coating solids applied (G) during each calendar month. Each monthly calculation is considered a performance test. Except as allowed by the provision below, the volume-weighted average of the total mass of VOCs emitted per unit volume of coating solids applied (N) each calendar month will be determined by the following procedures.

For each affected facility:

1) Calculate the mass of VOC's used (Mc+Md) during each calendar month using Equation E1 of Appendix J.

2) Calculate the total volume of coating solids used (Ls) in each calendar month using Equation E2 of Appendix J.

3) Determine the transfer efficiency using Table 1 of Appendix J. Use Equation E3 of Appendix J to determine the weighted average transfer efficiency if more than one application method is used within a single surface coating operation. If Permittee can demonstrate to the satisfaction of the Administrator that transfer efficiencies other than those shown in Table 1 are appropriate, the Administrator will approve their use on a case-by-case basis. Transfer efficiency values for application methods not listed in Table 1 shall be determined by the Administrator on a case-by-case basis. The Permittee must submit sufficient data for the Administrator to judge the accuracy of the transfer efficiency claims.

4) Calculate the volume-weighted average mass of VOCs consumed per unit volume of coating solids applied (G) during the calendar month using Equation E4 of Appendix J. This also equals the volume-weighted average of VOC emissions to the atmosphere (N) during the calendar month.

Compliance demonstration: Where the volume-weighted average mass of VOC discharged to the atmosphere per unit volume of coating solids applied (N) is less than or equal to 0.90 kilogram per liter, the affected facility is in compliance.

40 CFR Section 60.313(iii); Minn. R. 7011.2550

Provision to VOC emission calculation: If each individual coating used by an affected facility has a VOC content, as received, which when divided by the lowest transfer efficiency at which the coating is applied, results in a value equal to or less than 0.90 kilogram per liter, the affected facility is in compliance provided no VOC's are added to the coatings during distribution or application.

REPORTING AND RECORDKEEPING hdr

The reporting requirements of 40 CFR Section 60.8(a) (General Provisions) apply only to the initial performance test. Each owner or operator subject this subpart shall include the following data in the report of the initial performance test required under 40 CFR Section 60.8(a):

1) Except as allowed in paragraph 2), the Permittee shall provide the volume-weighted average mass of VOCs emitted to the atmosphere per volume of applied coating solids (N) for a period of one calendar month from each affected facility.

2) For each affected facility where compliance is determined under the VOC Emission Calculation Provision above, the Permittee shall include the following:

a. A list of the coatings used during a period of one calendar month;

b. The VOC content of each coating calculated from data determined using Method 24 or supplied by the manufacturer of the coating; and

c. The minimum transfer efficiency of any coating application equipment used during the month.

40 CFR Section 60.315(a)(1) and (2); 40 CFR Section 60.8(a);Minn. R. 7011.2550

The Permittee shall maintain at the source, for a period of at least 2 years, records of all data and calculations used to determine VOC emissions from each affected facility.
