§ 2101.20 DEFINITIONS

“General Multi

- Component Coating” means a coating requiring the addition of a separate

reactive resin, commonly known as a catalyst or hardener, before application to form an

acceptable dry film. {effective January 1, 201 4 }

“General One Component Coating” means a coating that is ready for application as it comes

out of its container to form an acceptable dry film. A thinner, necessary to reduce the viscosity,

is not considered a component. {effective January 1, 201 4 }

“ Soli ds turnover ratio (R T ) ” means the ratio of the total volume of coating solids that is added

to the electrodeposited primer system in a calendar month divided by the total volume design

capacity of the electrodeposited primer system

. {effective January 1, 201 4 }

determined by the test methods and procedures specified in Part G, shall be no

less than 85%.

c. Records. A facility, rega rdless of the facility’s annual emission rate, which contains an

automobile and/or light

- duty truck assembly coating operation, shall maintain records

sufficient to demonstrate compliance with this section. At a minimum, a facility shall

maintain daily re cords of:

1. The following parameters for each coating, thinner and other component as

supplied:

ADHESIVES

a. Applicability. Beginning January 1, 2014, this section applies to the owner or operator

of a miscellaneous industrial adhesive application process, where the total actual VOC

emissions from all miscellaneous industrial adhesives, including related cleanin g

activities, at that facility are equal to or greater than 15 pounds (6.8 kilograms) per day or

2.7 tons (2,455 kilograms) per twelve month rolling period, before controls.

b. Limitations. A person may not cause or permit the emission into the outdoo r

atmosphere of VOCs from a miscellaneous industrial adhesive process, unless one of the

following limitations is met:

1. The VOC content of each applied adhesive is equal to or less than the standard

specified in Table 2105.85.

A. The VOC content, minus exempt compounds, of the applied adhesive,

expressed in units of weight of VOC per volume of total nonexempt

material, shall be calculated as follows:

W

s - W

w - W

es VOC =

-----------------------

V

m - V

w - V

es

Where:

VOC = VOC content, minus exempt compounds, in lb (g) VOC /

gal (l) of materials, minus exempt compounds

W

s = W eight of all volatile material in pounds (g), including VOC,

water, non

- precursor organic compounds and dissolved vapors

W

w = Weight of water in pounds (g)

W

es = Weight of all non

- precursor compounds in pounds (g)

V

m = Volume of total material, as applied in gallons (l)

V

w = Volume of water in gallons (l)

V

es = Volume of all non

- pre cursor compounds in gallons (l)

B. The VOC content limits of subparagraph A may be met by averaging the

VOC content of materials used on a single application unit for each day

(i.e., daily within

- application unit averaging). 

### ALL NEW TEXT20 2. The overall weight of VOC emitted to the atmosphere is reduced through the use

of an oxidizer, adsorber, absorber or another add

- on control which is acceptable

under § 2105. 01 (Equivalent Compliance Techniques). The overall control

system, as determined by the test methods and pro cedures specified in Part G,

shall be no less than 85%.

3. A combination of the methods listed in paragraphs 1 and 2.

c. Records. A facility, regardless of the facility’s annual emission rate, which contains

miscellaneous industrial adhesive application processes, shall maintain records sufficient

to demonstrate compliance with this section. At a minimum, a facility shall maintain

d aily records of:

1. The following parameters for each adhesive and other component as supplied:

A. The name and identification number of each adhesive, or component;

B. The volume used;

C

. The mix ratio;

D

. The density or specific gravity;

E. The wei ght percent of total vol atiles, water, and exempt solvents;

F. The volume percent of total materials, water, and exempt solvents for

Table 2105.86 miscellaneous industrial adhesives

.

The records shall be maintained for 2 years and shall be submitted to the Department on a

schedule reasonably prescribed by the Department.

d. Exempt Solvents. The solvents methyl chloroform (1,1,1

- trichloroethane) and

methylene chloride are exempt from control under this Section. No miscellaneous

industrial adhesive ap plication process which seeks to comply with this Section through

the use of an exempt solvent may be included in any alternative standard approved

pursuant to this Article.

e. Application Techniques. A person may not cause or permit the emission into t he

outdoor atmosphere of VOCs from the application of miscellaneous industrial adhesives

unless the adhesives are applied using one or more of the following application methods:

1. Electrostatic spraying;

2. High volume

- low pressure (HVLP) spraying;

3. Flow coatin g;

4. Dip coating, including electrodeposition;

5. Airless spraying;

6. Air

- assisted airless spraying;

7. Roll coating or hand application, including non

- spray application methods similar

to hand or mechanically powered caulking gun, brush, or direct hand application ;21 8. Other adhesive application method that the person demonstrates and the

Department determines achieves emission reductions equivalent to HVLP

spraying.

f. Exempt Other. The following shall be exempt from the limitations set by Subsection b,

but shall st ill comply with the Subsection h, Housekeeping:

1. Adhesives or adhesive primers being tested or evaluated in any research and

development, quality assurance, or analytical laboratory.

2. Adhesives or adhesive primers used in the assembly, repair, or ma nufacture of

7. Processes using adhesives and adhesive primers that ar e supplied to the

manufacturer in containers with a net volume of 16 ounces or less, or a net weight

of one pound or less.

g. Emission Limitations. If an adhesive is used to bond dissimilar substrates together, then

the applicable substrate category w ith the least stringent emission limitation applies.

h. Housekeeping. The following work practices for cleaning materials apply to the owner

or operator of a miscellaneous industrial adhesive application processes:

1. Store all VOC

- containing adhesives, adhesive primers, process

- related waste

materials, cleaning materials and used shop towels in closed containers.

2. Ensure that mixing and storage containers used for VOC

- containing adhesives,

adhesive primers, process

- related waste materials, and cleaning materials are kept

closed at all times except when depositing or removing those materials.

3. Minimize spills of VOC

- containing adhesives

, adhesive primers, process

- related

waste materials, and cleaning materials, cleaning up spills immediat ely.22 4. Convey VOC

- containing adhesives

, adhesive primers, process

- related waste

materials, and cleaning materials from one location to another in closed containers

or pipes.

5. Minimize VOC emissions from cleaning of application, storage, mixing and

con veying equipment by ensuring that equipment cleaning is performed without

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

containers

.

i. Measurements. Measurements of the volatile fraction of adhesives, other than reactive

adh esives, used at facilities operating miscellaneous industrial adhesive application

processes shall be performed according to the applicable procedures established in
