Virginia Law

A. No owner or other person shall cause or permit the discharge into the atmosphere from a coating application system any volatile organic compound in excess of 2.9 pounds per gallon of coating, excluding water, as delivered by the coating applicator.

B. Achievement of the emission standard in subsection A of this section by use of methods in 9VAC5-40-4340 will be acceptable to the board.

C. The provisions of this section shall not be applicable to the production of packaging materials and to printing (graphic arts) operations to the extent provided in subsection D of this section.

D. The production of packaging materials involves two principal operations which emit volatile organic compounds: the coating and laminating of paper, film and foil, and the printing of words, designs and pictures upon webs of paper, film and foil. For the purposes of applicability of the above emission standard, coating is the application of a layer of material across any portion of the web and printing is the formation of words, designs and pictures, usually by a series of application rolls each with only partial coverage. The above emission standard applies to coating and laminating operations in the production of packaging materials, but does not apply to printing operations in the production of packaging materials and to publication rotogravure printing operations (the emission standards in Article 36 (9VAC5-40-5060 et seq.) of this chapter apply to such operations). However, all units in a machine which have both coating and printing units will be considered as performing a printing operation. A typical operation is as follows: the first unit applies a uniform background color, subsequent units print additional colors, the final unit applies a varnish overcoat. Such a machine would not be subject to the above emission standard, but would be subject to the emission standards in Article 36 (9VAC5-40-5060 et seq.) of this chapter.

E. No owner or other person shall use any coating application system or equipment unless reasonable precautions are taken to minimize the discharge or emissions from cleaning or purging operations. Reasonable precautions may include the following:

1. The use of capture or control devices or both;

2. The use of detergents, high pressure water, or other non-volatile cleaning methods;

3. The minimization of the quantity of volatile organic compounds used to clean lines of equipment; and

4. The adjustment of production schedules to minimize coating changes thereby reducing the need for frequent cleaning or purging of a system.
