RULE 424 - ARCHITECTURAL COATINGS
(Adopted 11/9/82; revised 9/14/99)

A. Applicability

This Rule is applicable to any Person who supplies, sells, offers for sale, applies or solicits the application of any Architectural Coating, or who manufactures any Architectural Coating for use within the District. Terms applicable to this Rule are defined in Rule 101 - Definitions.

A.1 Exemptions

The requirements of this Rule do not apply to:

A.1.a Architectural Coatings manufactured for use outside of the District or for shipment to other manufacturers for repackaging.

A.1.b Architectural Coatings supplied in and applied from containers having capacities of one liter or less, which were offered in containers of such capacities prior to1983.

A.1.c Architectural Coatings sold in non-refillable aerosol containers having capacities of one liter or less.

A.1.d Emulsion-type bituminous pavement sealers.

B. Standards

B.1 Except as provided in Subsections B.2, B.3, and B.4, no Person shall within the District, supply, offer for sale, sell, apply or solicit the application of any Architectural Coating which, at the time of sale or manufacture, contains more than 250 grams of Reactive Organic Compounds per liter of Coating (less water, and exempt solvents, and excluding any colorant added to the tint bases), or manufacture, blend or repackage such a Coating for use within the District.

B.2 Except as provided in Subsections B.3 and B.4, no Person shall, within the District, supply, offer for sale, sell, apply, or solicit the application of any Architectural Coating listed in the TABLE 424-1 which contains Reactive Organic Compounds (less water, and exempt solvents, and excluding any colorant added to tint bases) in excess of the corresponding limit specified in the table, after the corresponding date specified, or manufacture, blend or repackage such a Coating for use within the District.

B.3 If anywhere on the container of any Coating listed on Table 424-1, on any sticker or label affixed thereto, or in any sales or advertising literature, any representation is made that the Coating may be used as, or is suitable for use as a Coating for which a lower Reactive Organic Compound standard is specified in the table or in Section B.1, then the lowest Reactive Organic Compound standard shall apply. This requirement does not apply to the representation of the following Coatings in the manner specified:

B.3.a High Temperature Industrial Maintenance Coatings, which may be represented as metallic pigmented Coatings for use consistent with the definition of high temperature industrial maintenance Coatings;

B.3.b Lacquer Sanding Sealers, which may be recommended for use as Sanding Sealers in conjunction with clear lacquer Topcoats;

B.3.c Metallic Pigmented Coatings, which may be recommended for use as Primers, sealers, Undercoaters, Roof Coatings or industrial maintenance Coatings; and

B.3.d Shellacs.

B.4 All materials containing Reactive Organic Compounds shall be stored in closed containers when not in use. In use includes, but is not limited to: being accessed, filled, emptied, maintained or repaired.

C. Administrative Requirements

C.1 Each container of any Coating subject to this Rule shall display the date on which the contents were manufactured or a code indicating the date of manufacture. Each manufacturer of such Coatings shall file with the Air Pollution Control Officer and the Executive Officer of the California Air Resources Board, an explanation of each code.

C.2 Each container of any Coating subject to this Rule shall display a statement of the manufacturer's recommendation regarding thinning of the Coating. This recommendation shall not apply to the thinning of Architectural Coatings with water. The recommendation shall specify that the Coating is to be employed without thinning or diluting under normal environmental and application conditions unless any thinning recommended on the label for normal environmental and application conditions does not cause a Coating to exceed its applicable standard.

C.3 Each container of any Coating subject to this Rule and manufactured after (one year from the date of adoption) shall display the maximum ROC content of the Coating, as applied, and after any thinning as recommended by the manufacturer. The ROC content shall be displayed as grams of ROC per liter of Coating (less water and exempt solvent, and excluding any colorant added to tint bases). The ROC content displayed may be calculated using product formulation data, or may be determined using the test method in subsection D.1.

C.4 The volatile organic compound (VOC) content may be displayed instead of the Reactive Organic Compounds (ROC) content as long as the manufacturer's definition of VOC is consistent with the definition of ROC.

C.5 Beginning (one year from the date of adoption), the labels of all industrial maintenance Coatings shall include the statement "Not for Residential Use," or "Not for Residential Use in California," prominently displayed.

D. Test Methods

D.1 Measurement of Reactive Organic Compounds in Architectural Coatings shall be conducted and reported in accordance with EPA test Method 24 (40 CFR 60, Appendix A), "Determination of Volatile Matter Content, Water Content, Density, Volume Solids, and Weight Solids of Surface Coatings," or an equivalent method approved by the Air Pollution Control Officer, CARB and EPA.

D.2 Calculation for determination of ROC Content per volume of Coating:

(Wv - Ww - Wec) / (Rm - Rw - Rec)

Where:

Wv = weight of all Reactive Organic Compounds

Ww = weight of water

We = weight of compounds listed as exempt in the definition of ROC found in Rule 101

Rm = volume of Coating material

Rw = volume of water

Rec = volume of compounds listed as Exempt Compounds in Rule 101

D.3 Measurement of Reactive Organic Compounds from exempt organic compounds in Architectural Coatings shall be determined using California Air Resources Board Test Method 432, for Determination of Exempt Compounds.

D.4 Methylated siloxanes and perfluorocarbon compounds shall be assumed to be absent from a product or process unless a manufacturer or facility operator identifies the specific individual compounds (from the broad classes of methylated siloxanes an perfluorocarbon compounds) and the amounts present in the product or process and a validated test method to quantify the specific compounds.

D.5 Determination of metallics in metallic Coatings shall be made using South Coast Air Quality Management District (SCAQMD) Method 318- "Determination of Weight Percent Elemental Metal in Coatings by X-ray Defraction", as found in the SCAQMD Document Laboratory Methods of Analysis for Enforcement Samples.

D.6 Acidity in Volatile Solvents and in Coating Compounds shall be made using ASTM method D1613-85.
