Current through Register Vol. 51, No. 22, November 1, 2024

Section 26.11.35.04 - Standards

A. Except as provided in §E of this regulation and Regulation .01 of this chapter, on and after January 1, 2009, a person may not:

(1) Supply or offer for sale in the State an adhesive, sealant, adhesive primer, or sealant primer manufactured on or after January 1, 2009;

(2) Manufacture for sale in the State an adhesive, sealant, adhesive primer, or sealant primer in excess of the applicable VOC content limits specified in Table 1; or

(3) Use or apply an adhesive, sealant, adhesive primer, or sealant primer within the State that exceeds the applicable VOC content limits specified in Table 1.

B. The VOC content limits in Table 1 for adhesives applied to the listed substrates are as follows:

(1) If an operator uses an adhesive or sealant subject to a specific VOC content limit in Table 1, the specific limit, rather than an adhesive-to-substrate limit, is applicable; and

(2) If an adhesive is used to bond dissimilar substrates together, the applicable substrate category with the highest VOC content applies.

C. Surface Preparation or Cleanup Solvent.

(1) This section applies to a person subject to this chapter using a surface preparation or cleanup solvent.

(2) Except as provided in §C(3) of this regulation for single-ply roofing, a person may not use materials for surface preparation containing VOCs unless the VOC content of the surface preparation solvent is less than 70 grams per liter.

(3) If a surface preparation solvent is used in applying single-ply roofing, a person may not use materials for surface preparation containing VOCs unless the composite vapor pressure, excluding water and exempt compounds, of the surface preparation solvent does not exceed 45 millimeters of mercury at 20°C.

(4) Except as provided in §C(5) of this regulation, a person may not use materials containing VOCs for the removal of adhesives, sealants, or adhesive or sealant primers from surfaces, other than spray application equipment, unless the composite vapor pressure of the solvent used is less than 45 millimeters of mercury at 20°C.

(5) Removal of an adhesive, sealant, adhesive primer, or sealant primer from the parts of spray application equipment shall be performed as follows:

(a) In an enclosed cleaning system or equivalent cleaning system as determined by the test method identified in Regulation .06H of this chapter;

(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 the composite vapor pressure of the solvent, excluding water and exempt compounds, is less than or equal to 9.5 millimeters of mercury at 20°C and the parts and solvent are in a closed container that remains closed except when adding parts to or removing parts from the container.

D. A person using an adhesive, sealant, adhesive primer, or sealant primer subject to this chapter may comply with §§A(3) and C of this regulation using add-on air pollution control equipment if the equipment meets the following requirements:

(1) The VOC emissions from the use of all adhesives, sealants, adhesive primers, or sealant primers are reduced by an overall capture and control efficiency of at least 85 percent, by weight;

(2) The combustion temperature is monitored continuously if a thermal incinerator is operated;

(3) Inlet and exhaust gas temperatures are monitored continuously if a catalytic incinerator is operated;

(4) Control device efficiency is monitored continuously if a carbon absorber or control device other than a thermal or catalytic incinerator is operated;

(5) Operational records sufficient to demonstrate compliance with the requirements of this regulation are maintained as required by Regulation .05 of this chapter; and

(6) The control equipment is included in a permit to construct and operate.

E. A person using adhesives, sealants, adhesive primers, sealant primers, surface preparation solvents, or cleanup solvents subject to this chapter shall store or dispose of all absorbent materials, such as cloth or paper, that are moistened with adhesives, sealants, primers, or solvents subject to this chapter in nonabsorbent containers that are closed except when placing materials in or removing materials from the container.

F. A person may not solicit, require the use, or specify the application of an adhesive, sealant, adhesive primer, sealant primer, surface preparation solvent, or cleanup solvent if the use or application results in a violation of this chapter. This requirement applies to all written or oral contracts under which an adhesive, sealant, adhesive primer, sealant primer, surface preparation solvent, or cleanup solvent subject to this chapter is to be used at a location in the State.
