PART 219
ORGANIC MATERIAL EMISSION STANDARDS AND LIMITATIONS
FOR THE METRO EAST AREA
SECTION 219.780 EMISSION LIMITATIONS
Section 219.780 Emission
Limitations
a) Except as provided in Section 219.782 of this Subpart, no
owner or operator of a motor vehicle refinishing operation shall coat motor
vehicles, mobile equipment, or their parts and components, unless all coatings,
except touch-up coatings, never exceed the VOM content limitations in this
Section, expressed as units of VOM per volume of coating applied at each
coating applicator, minus water and any compounds that are specifically
exempted from the definition of VOM. The VOM content limitations are as follows:
|
|
kg/l
|
(lb/gal)
|
|
|
|
|
1)
|
Pretreatment wash primer
|
0.78
|

|
|
|
2)
|
Precoat
|
0.66
|
(5.5)

3)
|
Primer/primer surfacer coating
|
0.58
|
(4.8)
|
|
|
|
|
4)

system
|
0.63
|
(5.2)
|
|
|

7)
|
Sepcialty coatings

|
(7.0)
|
|
|
|
|
8)
|
Anti-glare/safety coating
|
0.84
|
(7.0)
|
b) All coating shall be used according to manufacturer's
specifications. If a coating requires the addition of a reducer, hardener, or
other additive, in some combination, this addition must not cause the coating,
as applied, to exceed the applicable VOM content limitation.
c) Specialty coatings shall represent no more than 5 percent, by
volume, of all coatings applied at a source on a monthly basis.
d) The following equations shall be used to calculate the VOM
content of topcoat systems:
1) The VOM content of basecoat/clearcoat systems shall be
calculated in units of kg VOM/l (lbs VOM/gal) of coating, (minus water and any
compounds which are specifically exempted from the definition of VOM),
according to the following equation:
![](03500219HH07800R_files/image001.gif)
Where:
VOM Tbc/cc
|
=
|
The weighted average of the
VOM content, as applied, in units of kg VOM/1 (lbs VOM/gal) of coating,
(minus water and any compounds which are specifically exempted from the
definition of VOM), in the basecoat (bc) and clearcoat (cc) system;
|
|
|
|
VOMbc
|
=
|
The VOM content, as applied,
in units of kg VOM/1 (lbs VOM/gal) of coating, (minus water and any compounds
which are specifically exempted from the definition of VOM), or any given
basecoat;
|
|
|
|
VOMcc
|
=
|
The VOM content, as applied,
in units of kg VOM/1 (lbs VOM/gal) of coating, (minus water and any compounds
which are specifically exempted from the definition of VOM), of any given
clearcoat.
|
2) The VOM content for a three stage coating system shall be
calculated in units of kg VOM/l (lbs VOM/gal) of coating, (minus water and any
compounds which are specifically exempted from the definition of VOM),
according to the following formula:
![](03500219HH07800R_files/image002.gif)
Where:
VOM Tms
|
=
|
The weighted average of the
VOM content, as applied, in units of kg VOM/1 (lbs VOM/gal) of coating,
(minus water and any compounds which are specifically exempted from the
definition of VOM), in the basecoat, midcoat and clearcoat system;
|
|
|
|
VOMbc
|
=
|
The VOM content, as applied,
in units of kg VOM/1 (lbs VOM/gal) of coating, (minus water and any compounds
which are specifically exempted from the definition of VOM), or any given
basecoat;
|
|
|
|
VOMmc
|
=
|
The VOM content, as applied,
in units of kg VOM/1 (lbs VOM/gal) of coating, (minus water and any compounds
which are specifically exempted from the definition of VOM), of any given
midcoat; and
|
|
|
|
VOMcc
|
=
|
The VOM content, as applied,
in units of kg VOM/1 (lbs VOM/gal) of coating, (minus water and any compounds
which are specifically exempted from the definition of VOM), of any given
clearcoat.
|
3) The VOM content for a four stage coating system shall be
calculated in units of kg VOM/l (lbs VOM/gal) of coating, (minus water and any
compounds which are specifically exempted from the definition of VOM),
according to the following formula:
![](03500219HH07800R_files/image003.gif)
Where:
|
|
|
|
|
|
VOM Tms
|
=
|
The weighted average of the
VOM content, as applied, in units of kg VOM/1 (lbs VOM/gal) of coating,
(minus water and any compounds which are specifically exempted from the
definition of VOM), in the basecoat, midcoats and clearcoat system;
|
|
