Section 215.5.PPP or 215.5.RRR, the reference method is U.S. EPA Method 24, except as provided in
Sections 215.9.C and 215.9.D. An alternative method to determine the VOC content of coatings is
SCAQMD Method 304-91 (Revised 1996). The exempt compounds content shall be determined by
SCAQMD Method 303-91 (Revised 1993), BAAQMD Method 43 (Revised 1996), or BAAQMD
Method 41 (Revised 1995). To determine the VOC content of a coating, the manufacturer may use U.S.
EPA Method 24, or an alternative method as provided in Section 215.9.C, formulation data, or any other
reasonable means for predicting that the coating has been formulated as intended (e.g., quality assurance,
checks, recordkeeping). If there are any inconsistencies between the results of a Method 24 test and any
other means for determining VOC content, the Method 24 test results will govern, except when an
alternative method is approved as specified in Section 215.9.C. The APCO may require the manufacturer
to conduct a Method 24 analysis.
C. ALTERNATIVE TEST METHODS: Other test methods may also be used if demonstrated to provide

215.10 VIOLATIONS
A. Failure to comply with any provision of this rule shall constitute a violation of this rule.
215.3 COMPLIANCE PROVISIONS AND TEST METHODS:
A. CALCULATION OF VOC CONTENT: For the purpose of determining compliance with the VOC
content limits in the Table of Standards, the VOC content of a coating shall be determined as defined in
Sections 215.9TTT215.5.PPP, 215.59.QQQUUU, or 215.59.RRRVVV. The VOC content of a tint base
shall be determined without colorant that is added after the tint base is manufactured. If the manufacturer
does not recommend thinning, the VOC Content must be calculated for the product as supplied. If the
manufacturer recommends thinning, the VOC Content must be calculated including the maximum
amount of thinning solvent recommended by the manufacturer. If the coating is a multi-component
product, the VOC content must be calculated as mixed or catalyzed. If the coating contains silanes,
siloxanes, or other ingredients that generate ethanol or other VOCs during the curing process, the VOC
content must include the VOCs emitted during curing.
B. VOC CONTENT: To determine the physical properties of a coating to perform the calculations in
Section 215.9TTT 215.5.PPP or 215.95.VVVRRR, the reference method is U.S. EPA Method 24, except
as provided in Sections 215.7C 215.9.C and 215.7D9.D. An alternative method to determine the VOC
content of coatings is SCAQMD Method 304-91 (Revised 1996). The exempt compounds content shall
be determined by SCAQMD Method 303-91 (Revised 1993), BAAQMD Method 43 (Revised 1996), or
BAAQMD Method 41 (Revised 1995). To determine the VOC content of a coating, the manufacturer
may use
U.S. EPA Method 24, or an alternative method as provided in Section 215.7C215.9.C, formulation data,
or any other reasonable means for predicting that the coating has been formulated as intended (e.g.,
quality assurance, checks, recordkeeping). If there are any inconsistencies between the results of a
Method 24 test and any other means for determining VOC content, the Method 24 test results will
govern, except when an alternative method is approved as specified in Ssection 215.7C215.9.C. The
APCO may require the manufacturer to conduct a Method 24 analysis.
C. ALTERNATIVE TEST METHODS: Other test methods may also be used if demonstrated to provide
results that are acceptable for purposes of determining compliance with Section 215.7B 215.9.B and after
review and approval by the staff of the District, the CARB, and the U.S. EPA.
D. METHACRYLATE TRAFFIC MARKING COATINGS: Analysis of methacrylate multicomponent
