303 SPECIALTY COATINGS PURPOSE: If anywhere on the container of any coating listed in Sections 302 or 306, on any sticker or label affixed thereto, or in any sales or advertising literature, any representation is made that the coating may be used, or is suitable for use as a coating for which a lower VOC standard is specified in Sections 301, 302, or 306, then the lowest VOC standard shall apply. This requirement does not apply to the representation of the following coatings in the specified manner:

304 STORAGE REQUIREMENTS: All VOC-containing materials 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.

305 CLEANUP REQUIREMENTS: A person shall not use volatile organic compounds for the cleanup of spray equipment unless equipment for collection of the cleaning compounds and minimizing its evaporation to the atmosphere is used.

306 LOW-SOLIDS STAINS: Except as provided in Section 303, effective January 1, 1994, no person shall sell, solicit, offer for sale, or apply any low-solids stain nor manufacture, blend, or repackage such a coating, which contains volatile organic compounds (less exempt compounds, excluding any colorant added to the tint bases) in excess of 120 grams of VOC per liter of coating as applied.

400 ADMINISTRATIVE REQUIREMENTS

401 LABELING REQUIREMENT: DATE OF MANUFACTURE: Each container of any coating subject to this rule shall display the date of manufacture of the contents or a code indicating the date of manufacture. The 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.

402 LABELING REQUIREMENT: THINNING RECOMMENDATIONS: Each container of any coating subject to the requirements of this rule shall display a statement of the manufacturer's recommendation regarding thinning of the coating. This requirement 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 the recommended thinning for normal environmental and application conditions does not cause the coating to exceed its applicable standard.

403 LABELING REQUIREMENT: VOC CONTENT: Each container of any coating subject to this rule and manufactured after October 2, 1991 shall display the maximum VOC content of the coating, as applied, and after any thinning as recommended by the manufacturer. VOC content shall be displayed as grams of VOC per liter of coating (less water and exempt compounds, and excluding any colorant added to tint bases). For low-solids stains, VOC content shall be displayed as grams of VOC per liter of coating, less exempt compounds and excluding any colorant added to tint bases. VOC content displayed may be calculated using product formulation data, or may be determined using the test method in Section 501.

404 CALCULATION FOR DETERMINATION OF VOC CONTENT PER VOLUME OF COATING: The volume of coating material is defined as the volume of the original coating, plus any VOC- containing material added to the original coating. The original coating is the coating before any VOC-containing material such as solvent is added for purposes of mixing or thinning. The VOC content shall exclude any colorant added to the tint bases. The weight of VOC per combined volume of VOC and coating solids, shall be calculated by the following equation:

405 CALCULATION FOR DETERMINATION OF VOC CONTENT PER VOLUME OF MATERIAL: The volume of material is defined as the volume of the original material, plus any VOC- containing material added to the original material. The original material is the material before any VOC-containing material such as solvent is added for purposes of mixing or thinning. The VOC content shall exclude any colorant added to the tint bases. The weight of VOC per total volume of material shall be calculated by the following equation:

500 MONITORING AND RECORDS

501 TESTING PROCEDURE: A result by any of the below listed test methods which shows non- compliance with any provision of the rule shall constitute a violation of the rule.
