Rule 610. (1) A person shall not cause or allow the emission of volatile organic compounds from

the coating of automobiles and light-duty trucks, from any existing coating line, in excess of the

applicable emission rates shown in table 62.

(2) A person shall not cause or allow the emission of volatile organic compounds from the coating

of any of the following, from an existing coating line, in excess of the applicable emission rates

shown in column A of table 63 or the equivalent emission rates in column B of table 63:

(a) Cans.

(b) Coils.

(c) Large appliances.

(d) Metal furniture.

(e) Magnet wire.

(f) The nonmetallic surfaces of fabrics, vinyl, or paper.

(3) Subrule (2) of this rule notwithstanding, and as an alternative to the allowable emission rate

established by table 63, the existing paper coating lines at Fletcher Paper Company of Alpena may

comply with subrule (2) of this rule by not exceeding a volatile organic compound emission rate

of 180 tons per calendar year and 30 tons per calendar month.

(4) A person who is responsible for the operation of a coating line that is subject to this rule shall

obtain current information and keep records necessary for the determination of compliance with

this rule, as required in R 336.2041.

(5) For each coating line, compliance with the emission limits specified in table 62 and table 63

must be based upon all of the following provisions:

(a) For prime coat operations that utilize an electrodeposition process in automobile and light-

duty truck coating lines that are regulated under table 62, compliance must be based upon all

coatings that belong to the same coating category that is used during each calendar month

averaging period. For all other coatings, compliance must be based upon the volume-weighted

average of all coatings that belong to the same coating category and are used during each calendar

Page 15

day averaging period. The department may specifically authorize compliance to be based upon a

longer averaging period, which must not be more than 1 calendar month.

(b) If coatings that belong to more than 1 coating category are used on the same coating line

during the specified averaging period, then compliance must be determined separately for each

coating category.

(c) The information and records as required by subrule (4) of this rule.

(6) Compliance with the emission limits specified in this rule must be determined using 1 of the

following methods, as applicable:

(a) For the prime-electrodeposition process and for the final repair emission limits specified in

table 62, the method described in either R 336.2040(12)(a) if the coating line does not have an

add-on emissions control device or R 336.2040(12)(b) if the coating line has 1 or more add-on

emissions control devices.

(b) For the primer surfacer and topcoat emission limits specified in table 62, compliance must

be determined by the methodology described in the publication entitled "Protocol for Determining

the Daily Volatile Organic Compound Emission Rate of Automobile and Light-duty Truck

Topcoat Operations", EPA-453/R-08-002, adopted by reference in R 336.1902. References to

topcoat operations in this publication also apply to primer surfacer lines, with the following added

provisions:

(i) Unless specifically included in the adopted publication, if an anti-chip, color-in-prime,

blackout, or spot primer coating is applied as part of either a primer surfacer or topcoat coating

operation, then the anti-chip, color-in-prime, blackout, or spot primer coating must be included in

the transfer efficiency tests for that coating operation, conducted according to section 18 or 19 of

the adopted publication, and the transfer efficiency values in section 20 of the adopted publication

must not be used.

(ii) If spot primer is applied as part of a primer surfacer coating operation, then the daily usage

of spot primer, as calculated in section 8 of the adopted publication, may be derived from monthly

usage of spot primer based upon the number of vehicles processed in the primer surfacer operation

each day. If an add-on emissions control device is used on the coating line application area to

achieve compliance with the primer surfacer or topcoat emission limits specified in table 62, then

the capture efficiency must be determined in accordance with R 336.2040(10).

(c) For the emission limits specified in column B of table 63, the method described in either R

336.2040(12)(e) if the coating line does not have an add-on emissions control device or R

336.2040(12)(f) if the coating line has 1 or more add-on emissions control devices.

(d) For the emission limits specified in column A of table 63, the method described in either R

336.2040(12)(a) if the coating line does not have an add-on emissions control device or R

336.2040(12)(b) if the coating line has 1 or more add-on emissions control devices.

(7) The provisions of this rule, except for the provisions in subrule (4) of this rule, do not apply

to coating lines that are within a stationary source and that have a combined actual emission rate

of volatile organic compounds of less than 100 pounds per day or 2,000 pounds per month as of

November 4, 1999. If the combined actual emission rate equals or is more than 100 pounds per

day for a subsequent day or 2,000 pounds per month for a subsequent month, then this rule

permanently applies to the coating lines.

(8) A person may exclude low-use coatings that total 55 gallons or less per rolling 12-month

period at a stationary source from the provisions of this rule, except for subrule (4) of this rule.

Page 16

(9) Between November 1 and March 31, a person may discontinue the operation of a natural gas-

operation, then the anti-chip, color-in-prime, blackout, or spot primer coating is included in the

transfer efficiency tests for that coating operation, conducted according to section 18 or 19 of the

adopted publication, and the transfer efficiency values in section 20 of the adopted publication

must not be used.

(B) When spot primer is applied as part of a primer surfacer coating operation, then the daily

usage of spot primer, as calculated in section 8 of the adopted publication, may be derived from

monthly usage of spot primer based upon the number of vehicles processed in the primer surfacer

operation each day. If an add-on emissions control device is used on the coating line application

area to achieve compliance with the primer surfacer or topcoat emission limits specified in table

64-a, then the capture efficiency must be determined in accordance with R 336.2040(10).

(iii) For the final repair coating category emission limit specified in table 64-a, compliance must

be on an occurrence weighted average basis, calculated in accordance with the following equation,

in which clear coatings have a weighting factor of 2 and all other coatings have a weighting factor

of 1:

ꢄ

∑

ꢀꢁꢂ

VOCtot = ^2ꢀꢁꢂ

ꢃꢃ

ꢅ=1

department, a person may achieve the emission limits specified in subrule (1) of this rule by an

equivalent emission limit expressed in pounds of volatile organic compounds emitted per gallon

of applied coating solids. The equivalent emission limit is established by the following equation:

ꢇ

A =

(ꢉꢊ)

ꢋ

ꢈ

100

Where:

A = Allowable equivalent emission limit, pounds of volatile organic compounds per gallon of

applied coating solids.

E = Applicable emission limit as specified in subrule (1) of this rule, pounds of volatile organic

compounds per gallon of coating, minus water, as applied.

S = Solids volume fraction representative of a compliance coating, gallon of solids per gallon of

coating, minus water, as applied.

The value of "S" must be determined by using the following equation:

ꢇ

S = 1 -

7.36

(TE)_b= Overall baseline transfer efficiency of the coating line as specified in subrule (4) of this

rule, percent. If multiple application methods are used on the coating line, the overall baseline

transfer efficiency must be determined using the method described in R 336.2040(9). Department

approval of the transfer efficiency test method is required.

(4) For the purpose of establishing an equivalent emission limit under subrule (3) of this rule, the

value of (TE)b, the overall baseline transfer efficiency of the coating line must be 60%.

Notwithstanding this provision, a person may request, in writing to the department, and the

department may approve, a value for (TE)b that is less than 60%, but not less than 40%. A request

for a value for (TE)b of less than 60% must include a demonstration that the lower requested value

is representative of the overall transfer efficiency achieved by similar coating lines which use the

most efficient type of application equipment that is reasonably available for the similar coating

lines.

(5) A person that is responsible for the operation of a coating line that is subject to this rule shall

obtain current information, and keep daily records necessary, for the determination of compliance

with the provisions of this rule, as required in R 336.2041.

(6) For each coating line, compliance with the emission limits specified in this rule must be based

upon all of the following:

(a) The volume-weighted average of all coatings that belong to the same coating category, and

are used during each calendar day averaging period. The department may specifically authorize

compliance to be based upon a longer averaging period, not to exceed more than 1 calendar month.

Page 33

(b) If coatings that belong to more than 1 coating category are used on the same coating line

during the specified averaging period, then compliance must be determined separately for each

coating category.

(c) The information and records required by subrule (5) of this rule.

(7) Compliance with the emission limits specified in this rule must be determined using the

applicable method described in 1 of the following:

(a) For coating lines that are subject to the emission limits specified in subrule (1) of this rule,

the method described in either R 336.2040(12)(a) if the coating line has no add-on emissions

control device or R 336.2040(12)(b) if the coating line has 1 or more add-on emissions control

devices.

(b) For coating lines subject to the equivalent emission limits specified in subrule (3) of this rule,

the method described in either R 336.2040(12)(e) if the coating line has no add-on emissions

control device or R 336.2040(12)(f) if the coating line has 1 or more add-on emissions control

device.

(8) This rule does not apply to the coating of metallic surfaces that are subject to R 336.1610.

presence of the nonmetallic component. In this case, and if the nonmetallic component of the part

is plastic and used as an automobile, truck, or business machine plastic part, R 336.1632 applies

to the coating of the part.

(10) This rule, except for subrule (5) of this rule, does not apply to a metallic surface coating line

that complies with both of the following provisions:

(a) The coating line has an actual emission rate of volatile organic compounds equal to or less

than 2,000 pounds per month and 10.0 tons per year as of November 4, 1999. If the actual rate of

emissions from an exempted metallic surface coating line exceeds 2,000 pounds per month for a

subsequent month or 10.0 tons per year for a subsequent year, then the provisions of this rule

permanently applies to the metallic surface coating line for as long as the applicable equipment is

in operation.

(b) Volatile organic compound emissions from the coating line, when combined with the total

emissions of volatile organic compounds from all other metallic surface coating lines at the

stationary source that are exempted by this subrule, do not exceed 30.0 tons per year.

(11) A person may exclude low-use coatings that total 55 gallons or less per rolling 12-month

period at a stationary source from the provisions of this rule, except for subrule (5) of this rule.

(d) A metallic surface coating operation applicable to this rule, except for motor vehicle

materials, may choose to use an equivalent volatile organic compound emission rate limit based

on the use of a combination of low-volatile organic compound coatings specified in tables 64-e

and table 64-f, specified methods of application specified under subdivision (b) of this subrule,

and add-on controls. The overall emission reduction efficiency needed to demonstrate compliance

is determined each day as follows:

(i) Obtain the emission limitation from table 64-e or table 64-f. If using the lb volatile organic

compounds/gal coating, excluding water, as applied limit from table 64-e, then calculate the

emission limitation in a solids basis according to the following equation:

S = C / 1 – (C/7.36 lb/gal)

Where:

S = The volatile organic compound emission limitation in terms of lb volatile organic

compounds/gal of coating solids.

C = The volatile organic compound emission limitation in terms of lb volatile organic

compounds/gal of coating, excluding water, as applied.

(ii) Calculate the required overall emission reduction efficiency of the control system for the

day according to the following equation:

E = [(VOCa – S)/VOCa] x 100

Where:

E = The required overall emission reduction efficiency of the control system for the day.

Page 38

VOC_a= The maximum volatile organic compound content of the coatings, as applied, used each

day on the subject coating line, in units of lb volatile organic compounds/gal of coating solids, as

determined by the applicable test methods and procedures specified in subdivision (h) of this

subrule.

S = The volatile organic compound emission limitation in terms of lb volatile organic

compounds/gal of coating solids.

S = The volatile organic compound emission limitation in terms of lb volatile organic

compounds/gal of coating solids.

(e) A metallic surface coating operation applicable to this rule, with the exception of motor

vehicle materials, can choose to use add-on control equipment that must have an overall control

efficiency of 90% or higher. The coating operation would not have to limit the volatile organic

compound content of the coating materials and would not need to use any particular coating

application method.

(f) A person subject to this rule shall not cause or allow the emissions of volatile organic

compounds from existing motor vehicle material coating operations in any of the 2015 ozone

nonattainment areas in excess of the emission rates as specified in table 64-g, as applicable.

(g) If the provisions of more than 1 coating category of this subrule are applicable for a specific

coating, then the least stringent provision may be applied.

(h) For each coating line, compliance with the emission limits specified in this rule must be based

upon all of the following:

(i) The volume-weighted average of all coatings that belong to the same coating category, and

are used during each calendar day averaging period. Under R 336.1602(2), the department may

specifically authorize compliance to be based upon a longer averaging period, not to exceed more

than 1 calendar month.

(ii) If coatings that belong to more than 1 coating category are used on the same coating line

during the specified averaging period, then compliance must be determined separately for each

coating category.

(iii) The information and records required by subrule (5) of this rule.

Page 39

(i) Compliance with the emission limits specified in this rule must be determined using the

applicable method described in the following subdivisions:

(i) For coating lines that are subject to the emission limits specified in subdivision (c) of this

subrule, the method described in either R 336.2040(12)(a) if the coating line has no add-on

emissions control device or R 336.2040(12)(b) if the coating line has 1 or more add-on emissions

control devices.

(ii) For coating lines that are subject to the emission limits specified in subrule (3)(d) of this

rule, the method described in either R 336.2040(12)(c) if the coating line has no add-on emissions

control device or R 336.2040(12)(d) if the coating line has 1 or more add-on emissions control

devices.

(4) The following work practices are required for storage, mixing operations, and handling

operations for coatings, thinners, cleaning, and coating-related waste materials. The person

responsible for a metallic parts surface coating operation shall develop written procedures to

comply with the following provisions:

(a) Store all volatile organic compound-containing coatings, thinners, coating-related waste, and

cleaning materials in closed containers.

(b) Ensure that mixing and storage containers used for volatile organic compound-containing

coatings, thinners, coating-related waste, and cleaning materials are kept closed at all times, except

when depositing or removing these materials.

(c) Minimize spills of volatile organic compound-containing coatings, thinners, coating-related

waste, and cleaning materials.

(d) Convey volatile organic compound-containing coatings, thinners, coating-related waste, and

cleaning materials from 1 location to another in closed containers or pipes.

(e) Minimize volatile organic compound emission from cleaning of application, storage, mixing,

and conveying equipment by ensuring that equipment cleaning is performed without atomizing the

cleaning solvent and all spent solvent is captured in closed containers.

(5) A person who is responsible for the operation of a coating line that is subject to this rule shall

obtain current information, and keep daily records necessary for the determination of compliance

with the provisions of this rule, and as required in R 336.2041.

R 336.1622 Emission of volatile organic compounds from existing components of petroleum

refineries; refinery monitoring program.

Rule 622. (1) A person shall not cause or allow the emission of any volatile organic compound

from any existing component, as listed in subrule (2) of this rule, of a petroleum refinery, including

topping plants, unless all of the provisions of this rule are satisfied or unless an equivalent control

method, as approved by the department under R 336.1602(2), is implemented. An alternate

acceptable control method is described in “Standards of Performance for Equipment Leaks of VOC

in Petroleum Refineries for which Construction, Reconstruction, or Modification Commenced

After January 4, 1983, and on or Before November 7, 2006,” 40 CFR part 60, subpart GGG

adopted by reference in R 336.1902.

(2) A person shall not operate an existing petroleum refinery unless a monitoring program and

schedule approved by the department is implemented. This monitoring program and schedule must

provide for, and identify by type and refinery unit, by quarter, all of the following:

(a) An annual inspection of all of the following components:

Page 40

(i) Pump seals.

(ii) Process valves in liquid volatile organic compound service.

(iii) Process drains.

(iv) Components that are difficult to monitor.

(b) A quarterly inspection of all of the following components:

(i) Compressor seals.

(ii) Process valves in gaseous volatile organic compound service.

(iii) Pressure-relief valves in gaseous volatile organic compound service.

(c) A weekly visual inspection of all pump seals from which volatile organic compounds could

leak.

(d) An immediate inspection of any pump seal from which a liquid, including a volatile organic

compound, is observed dripping.

(e) An inspection of any relief valve from which a volatile organic compound could discharge

within 2 normal business days after it begins venting to the atmosphere.

(f) An inspection as soon as is practical, but not later than 2 normal business days, after the repair

of any component that was found leaking.

(3) Except for the visual inspections required by subrule (2)(c) of this rule, all inspections must

be performed using equipment and procedures as specified in 40 CFR part 60, appendix A, method

21, adopted by reference in R 336.1902. A component is leaking when a concentration of more

than 10,000 ppm, by volume, as methane or hexane, is measured by method 21.

(4) If implementation of the quarterly leak detection program as specified in subrule (2)(b) of this

rule shows that 2% or less of the process valves in a given refinery unit are leaking for 2

consecutive quarters, then the inspections of process valves in that refinery unit may be skipped

for 1 quarter. If 2% or less of the process valves in a given refinery unit are leaking for 5

consecutive quarters, then the inspections may be done annually. If a subsequent inspection shows

that if more than 2% of the process valves are leaking, then quarterly inspections of valves shall

again be required.

(5) The percent of valves leaking on a refinery unit, as referenced in subrule (4) of this rule, must

be determined by dividing the total number of valves found to be leaking on the refinery unit

during the specified monitoring period by the total number of valves on the refinery unit that are

required to be monitored by this rule.

(6) This rule does not apply to any of the following:

(a) Pressure-relief valves that vent to an operating flare header, fuel gas system, or vapor control

device.

(b) Components that are unsafe to monitor, until monitoring personnel would no longer be

exposed to immediate danger.

(c) Storage tank valves.

(d) Valves that are not externally regulated.

(e) Components that process, transfer, or contain 1 or more volatile organic compounds in the

liquid phase under actual conditions, all of which have a true vapor pressure of less than 1.55 psia.

(7) Notwithstanding the provisions of subrule (2) of this rule, the monitoring of components, such

as process drains and valves, that are used solely in effecting a refinery unit turnaround, is required

only within the quarter following the turnaround.

(8) A leak that is detected pursuant to the monitoring program provisions of subrule (2) of this

rule or for another reason must be repaired. Except as provided in subrule (10) of this rule, this

leak must be repaired as soon as possible, but not more than 15 days after the leak is detected.

Page 41

Until the time that the leak is repaired and retested verifying a successful repair, the component

causing the leak must bear a weather-resistant, numbered, identifying tag that indicates the date

the leak was discovered.

(9) A log of all leaks detected pursuant to the provisions of subrules (2), (3), (5), and (6) of this

rule or by another method must be maintained by the operator of the petroleum refinery. This log

must identify all of the following:

(a) The leaking component by type and location.

(b) The number of the identifying tag.

(c) The date the leak was discovered.

(d) The date the leak was repaired.

(e) The date the component was retested after the repair with an indication of the testing results.

(f) The person or persons who performed the inspections. The log must be made available to any

representative of the department during normal business hours of the refinery and be maintained

for a minimum of 2 years.

(10) If a leak cannot be repaired within 15 days due to circumstances beyond the control of the

operator of the petroleum refinery or because the leaking component cannot be repaired unless a

significant portion of the refinery unit is shut down for turnaround, then the operator shall maintain

a separate log of the non-repair. The log must identify all of the following:

(a) The leaking component by type, location, and refinery unit.

(b) The date the leak was discovered.

(c) The reason why the leak cannot be repaired within 15 days.

(d) The estimated date of repair.

(11) Within 25 days after the end of the previous quarter, the operator shall submit to the

department a report that contains all of the following information for that quarter:

(a) The total number of components tested, by type.

(b) The total number of components found leaking and repaired, by type.

(c) The accumulative total number of components, by refinery unit and type, found to be leaking

and not repaired within the required time period and the reason for non-repair.

(d) The type or types of monitoring equipment utilized during the quarter. The report required

by this subrule must be made on a form approved by the department.

(12) The department may require the early shutdown for turnaround of a refinery unit if the

department feels that there are a significant number of leaks that would justify this action.

(13) Except for safety pressure-relief valves, a person shall not operate existing petroleum

refinery equipment that has a valve at the end of a pipe or line that contains a volatile organic

compound, unless the pipe or line is sealed with a second valve, blind flange, plug, or cap. The

sealing device may be removed only when a sample is being taken or during maintenance

operations. A current, written description detailing routine sampling procedures and listing the

sealing devices involved must be maintained and be submitted to the department in an acceptable

format upon request.

technology to the allowable emission level resulting from the use of a pressure/vacuum

conservation vent meeting this requirement, the actual emission level must be determined using

the methods described in 40 CFR part 60, appendix A, and the allowable emission level must be

determined using the calculation methods described in appendix B of "Control of Volatile Organic

Emissions From Manufacture of Synthesized Pharmaceutical Products", EPA-450/2-78-029, both

(d) A miscellaneous plastic parts coating and pleasure craft coating operation applicable to this

rule can choose to use an equivalent volatile organic compound emission rate limit based on the

use of a combination of low-volatile organic compound coatings specified in table 68 to table 68-

c, specified methods of application specified under subdivision (b) of this subrule, and add-on

controls. The overall emission reduction efficiency needed to demonstrate compliance is

determined each day as follows:

(i) Obtain the emission limitation from table 68 to table 68-c. If using the pound of volatile

organic compound per gallon of coating, excluding water, as applied limit from table 68 or table

68-b, then calculate the emission limitation in a solids basis according to the following equation:

S = C / [1 – (C/7.36 lb/gal)]

Page 70

Where:

S = The volatile organic compound emission limitation in terms of pound of volatile organic

compound per gallon of coating solids.

C = The volatile organic compound emission limitation in terms of pound of volatile organic

compound per gallon of coating, (excluding water) as applied.

(ii) Calculate the required overall emission reduction efficiency of the control system for the

day according to the following equation:

E = [(VOC_a– S)/VOC_a] x 100

Where:

E = The required overall emission reduction efficiency of the control system for the day.

VOCa = The maximum VOC content of the coatings, as applied, used each day on the subject

coating line, in units of lb VOC/gal coating solids, as determined by the applicable test methods

and procedures specified in subdivision (h) of this subrule.

S = The volatile organic compound emission limitation in terms of pound of volatile organic

compound per gallon of coating solids.

(e) Should product performance requirements or other needs dictate the use of higher-volatile

organic compound materials than those that would meet the recommended emission limits, a

facility can choose to use add-on control equipment that must have an overall control efficiency

of 90% or higher instead of using low-volatile organic compound coatings and specified

application methods.

(f) For each coating line, compliance with the emission limits specified in this rule is based upon

all of the following:

(i) The volume-weighted average of all coatings that belong to the same coating category, and

are used during each calendar day averaging period. The department may specifically authorize

compliance, under R 336.1602(2), to be based upon a longer averaging period, not to exceed more

than 1 calendar month.

(ii) If coatings belonging to more than 1 coating category are used on the same coating line

during the specified averaging period, then compliance must be determined separately for each

coating category.

(iii) The information and records as required by subrule (6) of this rule.

(g) Compliance with the emission limits specified in subrule (4) of this rule, must be determined

using the method described in either R 336.2040(12)(a) if the coating line does not have an add-

on emissions control device or R 336.2040(12)(b) if the coating line has 1 or more add-on

emissions control devices.

(5) The following work practices are required for storage, mixing operations, and handling

operations for coatings, thinners, cleaning, and coating-related waste materials. The person

responsible for a miscellaneous plastic parts coating and pleasure craft coating operation shall

develop written procedures for compliance with the following provisions:

(a) Store all volatile organic compound-containing coatings, thinners, coating-related waste, and

cleaning materials in closed containers.

Page 71

(b) Ensure that mixing and storage containers used for volatile organic compound-containing

coatings, thinners, coating-related waste, and cleaning materials are kept closed at all times, except

when depositing or removing these materials.

(c) Minimize spills of volatile organic compound-containing coatings, thinners, coating-related

waste, and cleaning materials.

(d) Convey volatile organic compound-containing coatings, thinners, coating-related waste, and

cleaning materials from 1 location to another in closed containers or pipes.

(e) Minimize volatile organic compound emissions from cleaning of application, storage,

mixing, and conveying equipment by ensuring that equipment cleaning is performed without

atomizing the cleaning solvent and all spent solvent is captured in closed containers.

(6) A person that is responsible for the operation of a coating line that is subject to this rule shall

obtain current information and maintain daily records necessary for the determination of

compliance with the provisions of this rule, as required in R 336.2041.

R 336.1635 Emission of volatile organic compounds from existing offset lithographic and

letterpress printing lines in 2015 ozone nonattainment areas.

Rule 635. (1) As used in this rule:

(a) “Batch” means a supply of fountain solution that is prepared and used without alteration until

completely used or removed from the printing process. Batch applies to solutions prepared in

discrete batches or solutions that are continuously blended with automatic mixing units. A fountain

solution that is continuously blended with an automatic mixing unit is considered to be the same

batch until the recipe or mix ratio is changed.

(b) “Cleaning solution” means liquid solvents or solutions used to remove ink and debris from

the operating surfaces of the printing press and its parts including blanket washes, roller washes,

plate cleaners, metering roller cleaners, impression cylinder cleaners, rubber rejuvenators, and

other cleaners used for cleaning a press, press parts, or to remove dried ink from the areas around

a press. Cleaning solution does not include cleaners used on electronic components of a press, pre-

press cleaning operations, post-press cleaning operations, cleaning supplies used to clean the floor

of the area around a press, other than dried ink, or cleaning performed in parts washers or cold

cleaners.

(c) “Letterpress printing line” means all operations of letterpress printing processes characterized

by the image area being raised relative to the nonimage area and including, but not limited to, pre-

press and post-press operations that support the activity. Varnishes, glues, and other coatings that

are applied by a letterpress printing process are part of the letterpress printing operations and are

not considered as a separate process, for example, paper coating.

(d) “Non-heatset” means a lithographic printing process where the printing inks are set without

the use of heat and dry by absorption or oxidation, or both. For the purposes of this rule, use of an

infrared heater or printing conducted using ultraviolet-cured or electron beam-cured inks is

considered non-heatset.

(e) “Offset lithographic printing line” means offset printing presses characterized by a

planographic plate where the image and nonimage area are in the same geographical plane and the

related processes necessary to directly support the operation of those offset lithographic printing

processes including, but not limited to, pre-press and post-press operations. Varnishes, glues, and

other coatings that are applied by an offset lithographic printing process are part of offset

Page 76

lithographic printing operations and are not considered as a separate process, for example, paper

coating.

(f) “Printing process” means any equipment, operation, or system where printing ink or a

combination of printing ink, surface coating, or adhesive is applied, dried, or cured. A printing

process may include any equipment that applies, conveys, dries, or cures inks or surface coatings

including, but not limited to, presses, digital output devices, fountain solutions, heaters, and dryers.

(2) A person shall not cause or allow the emission of any volatile organic compound from an

offset lithographic and letterpress printing line located in the 2015 ozone nonattainment area, in
