Section 250-RICR-120-05-44.10 - Compliance Provisions and Test Methods

A. Except as provided in §§ 44.10(B) through (E) of this Part, the VOC and solids content of all non-aerosol adhesives, adhesive primers and cleanup solvents shall be determined using 40 C.F.R. § 60, Appendix A-7, Method 24 incorporated in § 44.4(A) of this Part, or South Coast Air Quality Management District (SCAQMD) Method 304, incorporated in § 44.4(D) of this Part.

B. The organic content of exempt organic compounds shall be determined using ASTM D 4457-85, as applicable, incorporated in § 44.4(B) of this Part.

C. The VOC content of any plastic cement welding adhesive or primer shall be determined using SCAQMD Method 316A, incorporated in § 44.4(D) of this Part.

D. To determine if a diluent is a reactive diluent, the percent of the reactive organic compound that becomes an integral part of the finished materials shall be determined using SCAQMD Method 316A, incorporated in § 44.4(D) of this Part.

E. The composite vapor pressure of organic compounds in cleaning materials shall be determined by quantifying the amount of each compound in the blend using gas chromatographic analysis (ASTM E 260-96) for organics and ASTM D 3792-16 for water content, as applicable and incorporated in § 44.4(B) of this Part, and the following equation:

F. The vapor pressure of each single component compound may be determined from ASTM D 2879-10, incorporated in § 44.4(B) of this Part or may be obtained from any of the following sources:

1. The Vapor Pressure of Pure Substances, Boublik, Fried, and Hala; Elsevier Scientific Publishing Company, New York;

2. Perry's Chemical Engineer's Handbook, McGraw-Hill Book Company;

3. CRC Handbook of Chemistry and Physics, CRC Press, Taylor & Francis Group;

4. Lange's Handbook of Chemistry, John Dean, editor, McGraw-Hill Book Company; or

5. Additional sources approved by the Department.

G. If air pollution control equipment is used to meet the requirements of this rule, the owner or operator shall make the following determinations:

1. The measurement of capture efficiency shall be conducted and reported in accordance with the EPA Technical Document "Guidelines for Determining Capture Efficiency," incorporated in § 44.4(E) of this Part; and

2. The control efficiency shall be determined in accordance with 40 C.F.R. Appendix A-7 Methods 25, 25A, 25B, incorporated in § 44.4(A) of this Part or Method 100, incorporated in § 44.4(C) of this Part.

H. The active and passive solvent losses from spray gun cleaning systems shall be determined using SCAQMD's "General Test Method for Determining Solvent Losses from Spray Gun Cleaning Systems," incorporated in § 44.4(D) of this Part. The test solvent for this determination shall be any lacquer thinner with a minimum vapor pressure of 105 mm of Hg at twenty degrees Celsius (20°C), and the minimum test temperature shall be fifteen degrees Celsius (15°C).

I. For adhesives that do not contain reactive diluents, grams of VOC per liter of adhesive, less water, shall be calculated according to the following equation:

J. For adhesives that contain reactive diluents, the VOC content of the adhesive is determined after curing. The grams of VOC per liter of adhesive, less water, shall be calculated according to the following equation:

K. Grams of VOC per liter of material shall be calculated according to the following equation:
