“VOC Actual” means the weight of VOC per volume of coating and it is calculated with the following 

equation: 

 (Ws ̶ Ww ̶ Wec) 

 VOC Actual = 

 (Vm) 

Where: 

 VOC Actual = the grams of VOC per liter of coating (also known as “Material 

VOC”) 

Ws = weight of volatiles, in grams 

Ww = weight of water, in grams 

Wec = weight of exempt compounds, in grams 

Vm = volume of coating, in liters 

“VOC Content” means the weight of VOC per volume of coating. VOC Content is “VOC Regulatory,” 

as defined in Section C of this rule, for all coatings except for those in the Low Solids category. For 

coatings in the Low Solids category, the VOC Content is “VOC Actual,” as defined in Section C of this 

rule. If the coating is a multicomponent coating, the VOC Content is “VOC Regulatory” 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 shall include the VOCs emitted during curing. 

“VOC Regulatory” means the weight of VOC per volume of coating, less the volume of water and exempt 

compounds. It is calculated with the following equation: 

 (Ws ̶ Ww ̶ Wec) 

 VOC Regulatory = 

 (Vm ̶ Vw ̶ Vec) 

Where: 

VOC Regulatory = grams of VOC per liter of coating, less water and exempt compounds 

(also known as “Coating VOC”) 

Ws = weight of volatiles, in grams 

Ww = weight of water, in grams 

Wec = weight of exempt compounds, in grams 

Vm = volume of coating, in liters 

Vw = volume of water, in liters 

Vec = volume of exempt compounds, in liters

“Waterproofing Membrane” means any clear or opaque coating that is labeled and formulated for

Santa Barbara County APCD Rule 323.1 323.1 - 16 June 19, 2014 

G. Compliance Provisions and Test Methods 

1. Calculation of VOC Content: For the purpose of determining compliance with the VOC Content 

limits in Table 323.1-1, the VOC Content of a coating shall be determined using the procedure 

described in the appropriate Section C definition. 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 shall be calculated for the product as supplied. If 

the manufacturer recommends thinning, the VOC Content shall be calculated including the 

maximum amount of thinning solvent recommended by the manufacturer. If the coating is a 

multicomponent coating, the VOC Content shall 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 shall include the VOCs emitted during curing. 

2. VOC Content of Coatings: To determine the physical properties of a coating in order to perform 

the calculations in the Section C definition for VOC Actual for low solids coatings or the Section 

C definition for VOC Regulatory for all other architectural coatings, the reference method for 

VOC Content is the Environmental Protection Agency Method 24, incorporated by reference in 

Section G.5.h, except as provided in Sections G.3 and G.4. An alternative method to determine the 

VOC Content of coatings is South Coast Air Quality Management District Method 304-91 

(Revised 1996), “Determination of Volatile Organic Compounds (VOC) in Various Materials,” 

incorporated by reference in Section G.5.i. The exempt compounds content shall be determined by 

South Coast Air Quality Management District Method 303-91 (Revised 1996), “Determination of 

Exempt Compounds,” or the Bay Area Air Quality Management District Method 43 (Revised 

2005), “Determination of Volatile Methylsiloxanes in Solvent-Based Coatings, Inks, and Related 

Materials,” or the Bay Area Air Quality Management District Method 41 (Revised 2005), 

“Materials Containing Parachlorobenzotrifluoride,” as applicable, incorporated by reference in 

Sections G.5.g, G.5.e, and G.5.f, respectively. To determine the VOC Content of a coating, the 

manufacturer may use the Environmental Protection Agency Method 24, or an alternative method 

as provided in Section G.3, formulation data, or any other reasonable means for predicting that the 

coating has been formulated as intended (e.g., quality assurance checks, recordkeeping). However, 

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 G.3. The Control Officer may require the manufacturer 

to conduct a Method 24 analysis. 

3. Alternative Test Methods: Other test methods demonstrated to provide results that are acceptable 

for purposes of determining compliance with Section G.2, after review and approved in writing by 

the staffs of the District, the California Air Resources Board, and the Environmental Protection 

Agency, may also be used. 

4. Methacrylate Traffic Marking Coatings: Analysis of methacrylate multicomponent coatings 

used as traffic marking coatings shall be conducted according to a modification of Environmental 

Protection Agency Method 24 (40 CFR part 59, subpart D, appendix A), incorporated by reference 

in Section G.5.j. This method has not been approved for methacrylate multicomponent coatings 

used for other purposes than as traffic marking coatings or for other classes of multicomponent 

coatings.

linear completely methylated siloxanes, shall be analyzed as exempt compounds for 

compliance with Section G by Bay Area Air Quality Management District Method 43
