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
