On August 11, 2020, the San Diego Air Pollution Control District (SDAPCD) released a public notice proposing amendments to Rule 67.0.1 - Architectural Coatings. The proposed amendments will establish new coating categories and corresponding VOC content limits, establish new VOC content limits for colorants added to coatings, and lower VOC content limits for various existing coating categories. Additional changes are proposed to restrict exemptions from architectural coatings.

The proposed amendment will include several changes, including but not limited to:

  • Lower VOC content limits for certain existing coating types such as non-flat coatings, where their VOC content limit will decrease from 100 to 50 grams/liter.
  • Stains will be split into two (2) new coating categories, exterior/dual stain and interior. The VOC content limit of exterior/dual stain will remain at 250 grams/liter while the VOC content limit of interior will decrease from 250 to 100 grams/liter.
  • Colorants of coatings will be a new category. Colorants will be applicable to specific VOC content limits based on the category of the coatings they are being added to.
  • Exemption to Rule 67.01 with regards to any architectural coating sold in a container with a volume of 1 liter or less will not be applicable to coating containers bundled together with other containers of the same specific coating category when the total volume will exceed 1 liter.

As a permit exempt source, the compliance of architectural coating usage is often overlooked. Since the rule will be changing, it is a great time to verify the compliance of your current products and determine which ones will need to be changed.
