9 Va. Admin. Code § 5-40-8384

Current through Register Vol. 41, No. 4, October 8, 2024

Section 9VAC5-40-8384 - Standard for volatile organic compounds

A. No owner or other person shall use or permit the use of any letterpress printing press, letterpress printing process, or other letterpress printing operation that is subject to this article unless that press, process, or operation meets the requirements of this section.

B. The following provisions apply to each dryer on each heatset web letterpress printing process, except that these provisions do not apply to (i) any heatset web letterpress printing process with a theoretical potential to emit less than 25 tons per year of VOC (petroleum ink oil) from the dryer, prior to controls; (ii) any heatset web letterpress printing process used exclusively for book printing; or (iii) any heatset web letterpress printing process with a maximum web width of 22 inches or less. These provisions also do not apply to non-heatset web letterpress printing processes or to sheet-fed letterpress printing processes.

1. VOC emissions from the heatset web letterpress printing process dryer shall be controlled as follows:

a. The dryer shall operate at a lower air pressure than the pressroom air pressure at all times when the printing process is operating;

b. Exhaust air from the dryer shall be collected and sent to a control device that operates at all times when the printing process is operating.

c. For a control device whose first installation date is prior to February 1, 2016, the control device shall reduce VOC emissions in the dryer air exhaust by at least 90%.

d. For a control device whose first installation date is on or after February 1, 2016, the control device shall reduce VOC emissions in the dryer air exhaust by at least 95%.

2. Where the heatset web letterpress printing process control device inlet VOC concentration is too low to achieve the control device efficiency requirements specified in subdivisions 1 c and 1 d of this subsection or there is no identifiable measurable inlet, the control device shall reduce the VOC concentration of the heatset web letterpress printing process dryer exhaust air to 20 parts per million volume (ppmv) or less, as hexane on a dry basis.

3. Federally enforceable limitations on (i) the VOC (petroleum ink oil) content of inks and coatings applied prior to the dryer, (ii) the total amounts of inks and coatings applied, (iii) the press application rates of inks and coatings, or (iv) the hours of press operation may be used to meet the 25 ton per year exception to this subsection.

C. Cleaning materials used at each letterpress printing operation shall meet one of the following limits, as applied:

1. A VOC content of 70% by weight; or

2. A composite vapor pressure of 10 mm Hg at 20°C.

The use of cleaning materials not meeting the limits in subdivision 1 or 2 of this subsection is permitted provided that the quantity of cleaning material used does not exceed 110 gallons over any 12-month rolling period.

D. The following work practices shall be implemented:

1. Cleaning materials, inks, and coatings containing VOCs shall be kept in closed containers at all times unless filling, draining, or performing cleaning operations.

2. Shop towels, sponges, and other manual cleaning aids (i) that have been used for picking up excess ink and other coatings containing VOCs or (ii) that have been used with cleaning materials containing VOCs shall be kept in closed containers.

3. Spills of cleaning materials, fountain solution, inks, varnishes, and other coatings containing VOCs shall be minimized and shall be cleaned up promptly.
