The San Joaquin Valley Air Pollution Control District (SJVAPCD) hosted a Governing Board public hearing on April 16, 2020 to discuss the submittal of proposed amendments to District Rule 4601 to the Environmental Protection Agency (EPA). District Rule 4601 regulates volatile organic compound (VOC) emissions from architectural coatings. The proposed amendments include changes to applicability definitions and a contingency measure that will no longer allow for certain currently exempt coatings to be exempt when sold in containers of one liter or less. This contingency measure will be triggered if the EPA issues a final rulemaking stating progress has failed regarding the attainment of the 2008 8-hour Ozone National Ambient Air Quality Standard (NAAQS) in the San Joaquin Valley.
Additionally, the amendments include the update of the rule's requirements, which include reducing VOC limits starting on January 1, 2022 for eight types of coatings, establishing VOC limits for three new types of coatings, and establishing VOC limits for colorants.
