Section 218.219  Work Practice Standards for Automobile and Light-Duty Truck Assembly Coatings and Miscellaneous Metal and Plastic Parts Coatings

a)         Every owner or operator of a coating line subject to the requirements of Section 218.204(a)(2) of this Subpart shall:

1)         Store all VOM-containing coatings, thinners, coating-related waste materials, cleaning materials, and used shop towels in closed containers;

2)         Ensure that mixing and storage containers used for VOM-containing coatings, thinners, and coating-related waste materials are kept closed at all times except when depositing or removing those materials;

3)         Minimize spills of VOM-containing coatings, thinners, and coating-related

waste materials;

4)         Convey VOM-containing coatings, thinners, and coating-related waste

materials from one location to another in closed containers or pipes;

5)         Minimize VOM emissions from cleaning of storage, mixing, and conveying equipment;

6)         Develop and implement a work practice plan to minimize VOM emissions from cleaning and from purging of equipment associated with coating lines subject to the limitations in Section 218.204(a)(2).  The plan shall specify practices and procedures that the source will follow to ensure that VOM emissions from the operations listed in this subsection (a)(6) are minimized.  If the owner or operator of the subject coating line has already implemented a work practice plan for the coating line pursuant to Subpart IIII of 40 CFR 63, incorporated by reference in Section 218.112 of this Part, the owner or operator may revise the plan as necessary to comply with this Section.

A)        Vehicle body wiping;

B)        Coating line purging;

C)        Flushing of coating systems;

D)        Cleaning of spray booth grates, walls, and equipment; and

F)         Cleaning of external spray booth areas.

b)         Except as provided in subsection (c) of this Section, every owner or operator of a coating line described in Section 218.204(q) of this Subpart shall:

1)         Store all VOM-containing coatings, thinners, coating-related waste materials, cleaning materials, and used shop towels in closed containers;

2)         Ensure that mixing and storage containers used for VOM-containing coatings, thinners, coating-related waste materials, and cleaning materials are kept closed at all times except when depositing or removing these materials;

3)         Minimize spills of VOM-containing coatings, thinners, coating-related

waste materials, and cleaning materials;

4)         Convey VOM-containing coatings, thinners, coating-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 conveying equipment by ensuring that equipment cleaning is performed without atomizing the cleaning solvent and all spent solvent is captured in closed containers; and

6)         Apply all coatings using one or more of the following application methods:

A)        Electrostatic spray;

B)        High volume low pressure (HVLP) spray;

C)        Flow coating. For the purposes of this subsection (b)(6)(C), flow coating means a non-atomized technique of applying coating to a substrate with a fluid nozzle with no air supplied to the nozzle;

D)        Roll coating;

E)        Dip coating, including electrodeposition.  For purposes of this subsection (b)(6)(E), electrodeposition means a water-borne dip coating process in which opposite electrical charges are applied to the substrate and the coating.  The coating is attracted to the substrate due to the electrochemical potential difference that is created;

F)         Airless spray;

G)        Air-assisted airless spray; or

H)        Another coating application method capable of achieving a transfer efficiency equal to or better than that achieved by HVLP spraying, if the method is approved in writing by the Agency.

c)         Notwithstanding subsection (b) of this Section, the application method limitations in subsection (b)(6) shall not apply to the following:

1)         Coating lines complying with Section 218.207(n)(1);

2)         For metal parts and products coating operations:  touch-up coatings, repair coatings, textured finishes, stencil coatings, safety-indicating coatings, solid-film lubricants, electric-insulating and thermal-conducting coatings, magnetic data storage disk coatings, and plastic extruded onto metal parts to form a coating; 

3)         For pleasure craft surface coating operations:  extreme high gloss coatings; 

4)         For plastic parts and products coating operations:  airbrush operations using 18.9 liters (5 gallons) or less of coating per year;

5)         For ammunition sealant operations: cap sealants and mouth waterproofing sealants.
