Universal Citation: 06 ME Code Rules ยง 096-159-5

Current through 2024-38, September 18, 2024

Any person who sells, supplies, offers for sale or manufactures an adhesive, sealant, adhesive primer or sealant primer subject to this rule on or after January 1, 2011 for sale in Maine shall possess documentation that such adhesive, sealant, adhesive primer or sealant primer complies with the VOC limits in Table 1 of this rule, where the VOC content is determined according to the requirements of this section.

A. Except as provided in subsections 5(C), (D) and (E) of this section, the VOC and solids content of all non-aerosol adhesives, adhesive primers and cleanup solvents shall be determined using U.S. EPA Reference Method 24, as identified in 40 CFR 60, Appendix A, or SCAQMD Method 304.

B. The organic content of exempt organic compounds shall be determined using ASTM D4457-85, as applicable.

C. The VOC content of any plastic welding cement adhesive or primer shall be determined using SCAQMD Method 316A.

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.

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 260-91) for organics and ASTM D3792-79 for water content, as applicable, and the following equation:

Where:

Ppc = VOC composite partial pressure at 20 C, in mm Hg

Wi = Weight of the "i"th VOC compound, in grams, as determined by ASTM E 260-91

Ww = Weight of water, in grams as determined by ASTM D 3792-86

We = Weight of the "i"th exempt compound, in grams, as determined by ASTM E 260-91

Mwi = Molecular weight of the "i"th VOC compound, in grams per g-mole, as given in chemical reference literature

Mww = Molecular weight of water, 18 grams per g-mole

Mwe = Molecular weight of the "i"th exempt compound, in grams per g-mole, as given in chemical reference literature

Vpi = Vapor pressure of the "i"th VOC compound at 20 C, in mm Hg, as determined by subdivision (6) of this section

F. The vapor pressure of each single component compound may be determined from ASTM D2879-86 or may be obtained from any of the following sources:

(1) The most recent edition of The Vapor Pressure of Pure Substances, Boublik, Fried, and Hala; Elsevier Scientific Publishing Company, New York;

(2) The most recent edition of Perry's Chemical Engineer's Handbook, McGraw-Hill Book Company;

(3) The most recent edition of CRC Handbook of Chemistry and Physics, Chemical Rubber Publishing Company;

(4) The most recent edition of 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," issued January 9, 1995; and

(2) The control efficiency shall be determined in accordance with U.S. EPA Methods 25, 25A, 25B or CARB Method 100.

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," dated October 3, 1989. The test solvent for this determination shall be any lacquer thinner with a minimum vapor pressure of 105 mm of Hg at 20 degrees Celsius, and the minimum test temperature shall be 15 degrees Celsius.

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

Grams of VOC per liter of adhesive = Ws - Ww - We/ Vm - Vw - Ve

Where:

Ws = weight of volatile compounds, in grams

Ww = weight of water, in grams

We = weight of exempt compounds, in grams

Vm = volume of material, in liters

Vw = volume of water, in liters

Ve = volume of exempt compounds, in liters

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 and exempt compounds, shall be calculated according to the following equation:

Grams of VOC per liter of adhesive = Wrs - Wrw - Wre

Vrm - Vrw - Vre

Where:

Wrs = weight of volatile compounds not consumed during curing, in grams

Wrw = weight of water not consumed during curing, in grams

Wre = weight of exempt compounds not consumed during curing, in grams

Vrm = volume of material not consumed during curing, in liters

Vrw = volume of water not consumed during curing, in liters

Vre = volume of exempt compounds not consumed during curing, in liters

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

Grams of VOC per liter of materials = Ws - Ww - We

Vm

Where:

Ws = weight of volatile compounds, in grams

Ww = weight of water, in grams

We = weight of exempt compounds, in grams

Vm = volume of material, in liters

L. Percent VOC by weight shall be calculated according to the following equation:

% VOC by weight = [(Wv / W)] x 100

Where:

Wv = weight of VOCs in grams

W = weight of material in grams
