Virginia Law

A. The provisions of 9VAC5-40-20 (Compliance) apply.

B. The emission standards in 9VAC5-40-5080 A apply ink by ink and coating by coating or to the volume weighted average of inks or surface coatings where the inks and surface coatings are used on a single printing line and the inks and surface coatings are of the same type or perform the same function.

C. Inks and surface coatings meeting the criteria in 9VAC5-40-5080 A 1 through 3 (compliant inks and coatings) may be used on the same printing line with inks and surface coatings subject to the control requirements in 9VAC5-40-5080 (noncompliant inks and coatings) to meet the control requirements of 9VAC5-40-5080 without the installation of an add-on control system. When this is the case, compliance is determined by credits generated by the weight of volatile organic compounds by which the compliant inks or coatings are less than the applicable criteria in 9VAC5-40-5080 A 1 through 3. Compliance is demonstrated if the total credits in pounds of volatile organic compounds is equal to or greater than the total weight of volatile organic compound reduction required of the noncompliant inks over a time period not exceeding 24 hours.

D. Compliance with the requirements of 9VAC5-40-5130 B and C and the emission standards in 9VAC5-40-5080 A shall apply as follows:

1. To each printing line, and to parts of a printing line individually designated by the owner; or

2. To multiple printing lines controlled by a single solvent recovery system. For this option, the most stringent standard applicable to any of the printing lines is applied to all the lines controlled by the same solvent recovery system.

E. The emission standards in 9VAC5-40-5080 A shall apply to each successive compliance averaging period. This compliance averaging period shall not exceed:

1. 24 hours; or

2. The minimum compliance averaging period acceptable to the board, provided that:

a. The owner demonstrates to the satisfaction of the board that an averaging period of 24 hours or less does not adequately represent the reduction of volatile organic compound emissions over the same time period because of the physical or operational characteristics of an add-on control system;

b. The owner demonstrates to the satisfaction of the board the minimum compliance averaging period which adequately represents the reduction of volatile organic compound emissions; and

c. The owner determines compliance for each day or partial day of operation using the minimum compliance averaging period acceptable to the board.
