Section 250-RICR-120-05-44.7 - Emissions Limitations

A. Except as provided in §§ 44.6(B), 44.6(C), and 44.7(E) of this Part, no person shall manufacture, use, solicit the use of, sell, supply or offer for sale in Rhode Island any adhesive, sealant, adhesive primer or sealant primer that has a VOC content in excess of the applicable limit specified in §§ 44.7.1 and 44.7.2 of this Part.

B. For adhesives, the VOC content limits in §§ 44.7.1 and 44.7.2 of this Part shall apply as follows:

1. For adhesives listed in § 44.7.1 of this Part, the VOC content limits in § 44.7.1 of this Part, not the limits in § 44.7.2 of this Part, shall apply.

2. For adhesives not listed in § 44.7.1 of this Part, the applicable VOC content limit in § 44.7.2 of this Part, which are based on substrate category, shall apply. If an adhesive is used to bond two (2) different substrates, the applicable substrate category in § 44.7.2 of this Part with the higher VOC content shall apply.

C. For surface preparation solvents:

1. Except as provided in § 44.7(C)(2) of this Part, the VOC content of surface preparation solvents shall be less than seventy (70) grams per liter;

2. If a surface preparation solvent is used in applying single-ply roofing, the composite vapor pressure, excluding water and exempt compounds, of the surface preparation solvent shall not exceed forty-five (45) mm Hg at twenty degrees Celsius (20°C);

D. For cleanup solvents:

1. Except as provided in § 44.7(D)(2) of this Part, the composite vapor pressure, excluding water, of a cleanup solvent shall not exceed forty-five (45) mm Hg at twenty degrees Celsius (20°C);

2. Removal of an adhesive, sealant, adhesive primer or sealant primer from the parts of spray application equipment shall be performed:

a. In an enclosed cleaning system or equivalent cleaning system, as determined by the test method identified in § 44.10(H) of this Part, or

b. Using a solvent with a VOC content less than or equal to seventy (70) grams of VOC per liter of material. 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 mm Hg at twenty degrees Celsius (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.

E. A person using an adhesive, sealant, adhesive primer or sealant primer subject to this rule may comply with the VOC content limits in §§ 44.7.1 and 44.7.2 of this Part using air pollution control equipment, provided that such equipment meets the following requirements:

1. The air pollution control equipment reduces VOC emissions from all adhesives, sealants, adhesive primers or sealant primers used at the facility that are subject to this regulation by an overall capture and control efficiency of at least eighty-five percent (85%), by weight;

2. For thermal incinerators, the combustion temperature shall be monitored continuously;

3. For catalytic incinerators, inlet and exhaust gas temperatures shall be monitored continuously;

4. For control devices other than thermal or catalytic incinerators, including carbon absorbers, the control device efficiency shall be monitored continuously;

5. Records sufficient to demonstrate compliance with the requirements §§ 44.7(E)(1) though (4) of this Part shall be maintained as specified in § 44.9(B) of this Part.

6. A minor source permit or major source permit, issued pursuant to Part 9 of this Subchapter (Air Pollution Control Permits), has been issued for the air pollution control equipment. If the air pollution control equipment is exempt from the requirements to obtain a permit in Part 9 of this Subchapter (Air Pollution Control Permits), a registration form must be on file with the Office of Air Resources.

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

G. No person who applies or solicits the application of any adhesive, sealant, adhesive primer or sealant primer subject to this regulation shall add solvent to such adhesive, sealant or primer in an amount in excess of the manufacturer's recommendation for application, if such addition causes the adhesive, sealant or primer to exceed the applicable VOC content limit in §§ 44.7.1 and 44.7.2 of this Part.
