*The VOC content is determined using the weight of volatile compounds, less water and exempt compounds, as specified in 9VAC5-45-710 of this article.

B. Except as provided in 9VAC5-45-630 B through E, in subsection G of this section, and in 9VAC5-45-660, no person shall use, or apply for compensation, any adhesive, sealant, adhesive primer or sealant primer in excess of the applicable VOC content limits specified in Table 45-6A.

C. The VOC content limits in Table 45-6A for adhesives applied to particular substrates shall apply as follows.

1. If an owner or other person uses an adhesive or sealant subject to a specific VOC content limit for such adhesive or sealant in Table 45-6A, such specific limit is applicable rather than an adhesive-to-substrate limit.

2. If an adhesive is used to bond dissimilar substrates together, the applicable substrate category with the highest VOC content shall be the limit for such use.

D. No owner or other person shall use a surface preparation or cleanup solvent containing VOC unless:

1. The VOC content of the surface preparation solvent is less than 70 grams per liter, except as provided for single-ply roofing in subdivision 2 of this subsection;

2. The composite vapor pressure, excluding water and exempt compounds, of the surface preparation solvent used for applying single-ply roofing does not exceed 45 mm Hg at 20°C;

3. The composite vapor pressure of the solvent used for the removal of adhesives, sealants, or adhesive or sealant primers from surfaces other than spray application equipment is less than 45 mm Hg at 20°C, except as provided in subdivision 4 of this subsection; and

4. For the removal of adhesives, sealants, adhesive primers or sealant primers from parts of spray application equipment, the removal is performed as follows:

a. In an enclosed cleaning system, or equivalent cleaning system as determined by the test method identified in 9VAC5-45-710 I;

b. Using a solvent with a VOC content less than or equal to 70 grams of VOC per liter of material; or

c. Parts containing dried adhesive may be soaked in a solvent if (i) the composite vapor pressure of the solvent, excluding water and exempt compounds, is less than or equal to 9.5 mm Hg at 20°C, and (ii) the parts and solvent are in a closed container that remains closed except when adding parts to or removing parts from the container.

E. Any owner or other person using adhesives, sealants, adhesive primers, sealant primers, surface preparation or clean-up solvents subject to the provisions of this article shall store or dispose of all absorbent materials, such as cloth or paper, that are moistened with adhesives, sealants, primers or solvents subject to the provisions of this article, in nonabsorbent containers that shall be closed except when placing materials in or removing materials from the container.

F. No owner or other person shall solicit the use, require the use or specify the application of any adhesive, sealant, adhesive primer, sealant primer, surface preparation or clean-up solvent if such use or application results in a violation of the provisions of this article. This prohibition shall apply to all written or oral contracts under which any adhesive, sealant, adhesive primer, sealant primer, surface preparation or clean-up solvent subject to this article is to be used at any location within the areas designated in 9VAC5-45-620 C.

G. The standards for single-ply roof membrane installation and repair adhesive, single-ply roof membrane sealant, and single-ply roof membrane adhesive primer in Table 45-6A shall only apply as follows:

1. In the Northern Virginia and Fredericksburg VOC Emissions Control Areas: during the ozone seasons, or portions thereof, between August 1, 2010, and September 30, 2011, and on and after January 1, 2012; and

2. In the Richmond VOC Emissions Control Area: during the ozone season, or portion thereof, between March 1, 2014, and September 30, 2014, and after January 1, 2015.

H. The provisions of subsection A of this section and the provisions of 9VAC5-45-730 E do not apply to the sale, supply, offer for sale, or manufacture for sale of single-ply roof membrane installation and repair adhesive, single-ply roof membrane sealant, and single-ply roof membrane adhesive primer prior to January 1, 2012.
