The San Joaquin Valley Air Pollution Control District (SJVAPCD) hosted a public workshop on February 5, 2020 to discuss proposed amendments to District Rule 4601, which regulates volatile organic compound (VOC) emissions from architectural coatings. The proposed amendments are intended to further reduce VOC emissions, and the subsequent formation of ozone which will in turn create progress toward meeting the 2008 8-Hour Ozone National Ambient Air Quality Standard (NAAQS) in the San Joaquin Valley. The SJVAPCD is proposing to adopt a contingency measure in Rule 4601 that would take effect if the EPA issues a final rulemaking deeming that the San Joaquin Valley failed to make progress toward the attainment of the ozone NAAQS. If the contingency measure is triggered, the SJVAPCD will remove Rule 4601 exemption for specific categories of coatings sold in containers with a volume of one liter or less.

In addition to the proposed contingency measure, the SJVAPCD is also proposing to incorporate the California Air Resources Board's (CARB's) suggested control measure (SCM), adopted in May 2019, for architectural coatings to further help meet the ozone NAAQS. This update includes removing and/or modifying outdated definitions and requirements, lowering VOC limits for nine existing categories of coatings, and setting limits for three new categories of coatings. In addition, the amendment will incorporate new application and emission limits for photovoltaic coatings, which are currently under development by CARB, and establish VOC limits for colorants. The proposed limits and categories can be found on slide 9 of the SJVAPCD workshop presentation.
