(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 shall 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 shall 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 shall be based upon the volume-weighted  
average of all coatings which belong to the same coating category and which are used during  
each calendar day averaging period. The department may specifically authorize compliance to  
be based upon a longer averaging period, which shall 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 shall 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 shall be determined using the  
applicable method described in the following subdivisions:  
Page 11  
(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  
shall 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-450/3-88-018, adopted by reference in R 336.1902.  
References to topcoat operations in this publication shall 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 shall 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 shall 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 shall 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.

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 the effective date of this amendatory rule. 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 shall permanently apply 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.  
(9) Between November 1 and March 31, a person may discontinue the operation of a

coating lines.  
Rule 621. (1) A person shall not cause or allow the emission of volatile organic compounds  
from the coating of metallic surfaces from any existing coating line in excess of the applicable  
emission rates as follows:  
(a) Four and three-tenths pounds of volatile organic compounds emitted per gallon of  
coating, minus water, as applied for clear coatings.  
(b) Three and one-half pounds of volatile organic compounds emitted per gallon of coating,  
minus water, as applied for air-dried coatings.  
(c) Three and one-half pounds of volatile organic compounds emitted per gallon of coating,  
minus water, as applied for extreme performance coatings.  
(d) Four and eight-tenths pounds of volatile organic compounds emitted per gallon of  
coating, minus water, as applied for truck final repair coatings.  
(e) Four and nine-tenths pounds of volatile organic compounds emitted per gallon of  
coating, minus water, as applied for glass adhesion body primer. For the purpose of this  
subdivision, "glass adhesion body primer" means the prime coating that is applied to automobile  
or truck bodies as part of the glass bonding system.  
(f) Four and three-tenths pounds of volatile organic compounds emitted per gallon of  
coating, minus water, as applied for steel pail and drum interior coatings.  
(g) Three pounds of volatile organic compounds emitted per gallon of coating, minus water,  
as applied for all other coatings.  
(2) If the provisions of more than 1 subdivision of subrule (1) of this rule are applicable for a  
specific coating, then the least stringent provision shall apply.  
(3) To take credit for improved transfer efficiency, upon written request and approval by the  
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  
Page 20  
of applied coating solids. The equivalent emission limit shall be established by the following  
equation:  
E
A =  
(TE)  
100  
b
S
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" shall be determined by using the following equation:  
E
S = 1 -  
7.36  
(TE)b = Overall baseline transfer efficiency of the coating line as specified in subrule (4) of this  
rule, percent. Where multiple application methods are used on the coating line,  
the overall baseline transfer efficiency shall 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, shall 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% shall 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 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, as required in R 336.2041.  
(6) For each coating line, compliance with the emission limits specified in this rule shall be  
based upon all of the following:  
(a) The volume-weighted average of all coatings which belong to the same coating category  
and which are used during each calendar day averaging period. The department may specifically  
authorize compliance to be based upon a longer averaging period, which shall not be more than 1  
calendar month.  
Page 21  
(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 shall 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 shall be determined using the  
applicable method described in the following subdivisions:  
(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.

assembled on the marine vessel.  
(e) Coating of a part consisting of both metallic and nonmetallic components if a  
demonstration is made, to the satisfaction of the department, that the limits of this rule cannot be  
met due to the 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 shall apply 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 the effective date of this  
amendatory rule. 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 shall thereafter permanently apply to the metallic surface  
coating line.  
(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

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, is implemented. An alternate  
acceptable control method is described in 40 C.F.R., Part 60, Subpart GGG, “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,” 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

(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, which includes 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 of its 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.  
Page 23  
(3) Except for the visual inspections required by subrule (2)(c) of this rule, all inspections  
shall be performed using equipment and procedures as specified in 40 C.F.R. 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 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,  
shall 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) The provisions of this rule do 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 any other reason shall be repaired. Except as provided in subrule (10) of this rule,  
this leak shall be repaired as soon as possible, but not more than 15 days after the leak is  
detected. Until the time that the leak is repaired and retested verifying a successful repair, the  
component causing the leak shall 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 any other method shall be maintained by the operator of the petroleum refinery.  
This log shall 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.  
Page 24  
(f) The person or persons who performed the inspections. The log shall be made available  
to any representative of the department during normal business hours of the refinery and shall be  
kept 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 nonrepair. The log shall identify all of the following:  
(a) The leaking component by type, location, and refinery unit.  
(b) The date on which 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 of 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 nonrepair.  
(d) The type or types of monitoring equipment utilized during the quarter. The report  
required by this subrule shall 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 shall be maintained and, upon request by the department, shall be  
submitted to the department in an acceptable format.

R 336.1625 Emission of volatile organic compound from existing equipment utilized in  
manufacturing synthesized pharmaceutical products.  
Rule 625. (1) A person shall not cause or allow the emission of any volatile organic  
compound from existing equipment utilized in the manufacturing of synthesized pharmaceutical  
products, unless all of the provisions of the following subrules are met or unless an equivalent  
control method, as approved by the department, is implemented.  
Page 30  
(2) A person shall not operate an existing reactor, distillation operation, crystallizer,  
centrifuge, or vacuum dryer, unless the emissions from this equipment are controlled by either of  
the following:  
(a) A condenser, such that the outlet gas temperature does not exceed the following levels:  
(i) Minus 25 degrees Celsius (minus 13 degrees Fahrenheit) when the sum of the partial  
pressure or pressures of the volatile organic compound or compounds in the gas stream, as  
measured at 20 degrees Celsius (68 degrees Fahrenheit), is greater than 300 millimeters of  
mercury (5.8 pounds per square inch).  
(ii) Minus 15 degrees Celsius (5 degrees Fahrenheit) when the sum of the partial pressure  
or pressures of the volatile organic compound or compounds in the gas stream, as measured at 20  
degrees Celsius (68 degrees Fahrenheit), is greater than 150 millimeters of mercury (2.9 pounds  
per square inch).  
(iii) Zero degrees Celsius (32 degrees Fahrenheit) when the sum of the partial pressure or  
pressures of the volatile organic compound or compounds in the gas stream, as measured at 20  
degrees Celsius (68degrees Fahrenheit), is greater than 75 millimeters of mercury (1.5 pounds  
per square inch).  
(iv) Ten degrees Celsius (50 degrees Fahrenheit) when the sum of the partial pressure or  
pressures of the volatile organic compound or compounds in the gas stream, as measured at 20  
degrees Celsius (68 degrees Fahrenheit), is greater than 52.5 millimeters of mercury (1.0 pounds  
per square inch).  
(v) Twenty-five degrees Celsius (77 degrees Fahrenheit) when the sum of the partial  
pressure or pressures of the volatile organic compound or compounds in the gas stream, as  
measured at 20 degrees Celsius (68 degrees Fahrenheit), is greater than 26.2 millimeters of  
mercury (0.5 pounds per square inch).  
(b) An alternative control technology, the use of which results in an emission level no  
greater than would occur by meeting the provisions of subdivision (a) of this subrule. For  
purposes of comparing the actual emission level from an alternative control technology to the  
allowable emission level resulting from meeting the provisions of subdivision (a) of this subrule,  
the actual emission level shall be determined using the methods described in 40 C.F.R. Part 60,  
Appendix A and the allowable emission level shall 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 adopted by reference in R  
336.1902.  
(3) For the purpose of this rule, the sum of the partial pressure or pressures of the volatile  
organic compound or compounds in the gas stream is to be determined as follows:  
Where:  
n
(Pi)(Xi)  
Pt =  
i1  
Pt = Sum of the partial pressures of all volatile organic compounds.  
Pi = Vapor pressure of volatile organic compounds at 20 degrees Celsius (68 degrees  
Fahrenheit).  
Xi = Mole fraction of volatile organic compounds in liquid mixture.  
n = Number of different volatile organic compounds in liquid mixture.  
Page 31  
i = Individual volatile organic compound.  
The mole fraction, Xi, is determined as follows:  
Xi = moles of "i" in liquid mixture total moles of liquid mixture  
The total moles of liquid mixture shall include both the moles of volatile organic compounds  
and volatile inorganic compounds (such as water) in the liquid mixture.  
(4) Notwithstanding the provisions of subrule (2)(a) of this rule, a person shall not be  
required to reduce the temperature of a gas stream below the freezing point of a condensable  
component in that gas stream if it can be demonstrated, using intrinsic chemical data, to the  
satisfaction of the department, that in doing so, the condenser would be rendered ineffective. In  
this case, the temperature of the gas stream shall be reduced as low as can be achieved without  
freezing of the condenser occurring.  
(5) The provisions of this rule do not apply to any single existing reactor, distillation  
operation, crystallizer, centrifuge, or vacuum dryer that has a maximum uncontrolled volatile  
organic compound emission rate of less than 15 pounds per day.  
(6) A person shall not operate an existing air dryer or production equipment exhaust system  
unless the volatile organic compound emissions from this equipment are reduced by not less than  
90% if the uncontrolled volatile organic compound emissions are 330 pounds per day or more or  
are reduced to less than or equal to 33 pounds per day if the uncontrolled volatile organic  
compound emissions are less than 330 pounds per day.  
(7) A person shall not load or allow the loading of a volatile organic compound that has a  
vapor pressure of more than 210 millimeters of mercury (4.1 pounds per square inch), as  
measured at 20 degrees Celsius (68 degrees Fahrenheit), from a truck or railcar into an existing  
stationary vessel of more than a 2,000-gallon capacity, unless a vapor balance system or an  
alternate control system that provides not less than 90% control of loading emissions is utilized.  
(8) A person shall not store a volatile organic compound that has a vapor pressure of more  
than 75 millimeters of mercury (1.5 pounds per square inch), as measured at 20 degrees Celsius  
(68 degrees Fahrenheit), in an existing aboveground stationary vessel, unless the stationary  
vessel is equipped with a pressure/vacuum conservation vent set at plus or minus 1.5 millimeters  
of mercury (0.03 pounds per square inch) or an alternate control system at least as effective. For  
purposes of comparing the actual emission level from an alternative control technology to the  
allowable emission level resulting from the use of a pressure/vacuum conservation vent meeting  
this requirement, the actual emission level shall be determined using the methods described in  
40 C.F.R. Part 60, Appendix A, and the allowable emission level shall 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 adopted by  
reference in R 336.1902.  
(9) A person shall not operate an existing centrifuge, rotary vacuum filter, or other filter  
that has an exposed liquid surface, where the liquid contains a volatile organic compound or  
compounds and the sum of the partial pressure or pressures of volatile organic compound or  
compounds is 26.2 millimeters of mercury (0.5 pounds per square inch) or more, as measured at  
20 degrees Celsius (68 degrees Fahrenheit), unless the equipment is enclosed.  
(10) A person shall not operate an existing in-process tank that may contain a volatile  
organic compound at any time, unless the tank is equipped with a cover and the cover remains  
Page 32  
closed, except when production, sampling, maintenance, or inspection procedures require  
operator access.  
(11) A person shall not operate any existing equipment utilized in the manufacturing of  
synthesized pharmaceutical products from which a liquid containing a volatile organic  
compound or compounds can be observed dripping or running, unless the leak is repaired  
immediately, if possible, but not later than the first time the equipment is off-line for a period of  
time that is long enough to complete the repair.  
(12) A person who is responsible for the operation of a synthesized pharmaceutical process  
subject to the provisions of this rule shall obtain current information and maintain records that  
are necessary for a determination of compliance with the provisions of this rule. The information  
shall include all of the following:
