NC-v4 EQc2:Low emitting materials

North American projects - methylene chloride and perchloroethylene?

Seeking context if anyone has it....

Requirements include: "For projects in North America, methylene chloride and perchloroethylene may not be intentionally added in paints, coatings, adhesives, or sealants."

For clarity, is this automatically covered by compliance with SCAQMD / CARB standards, making this statement more of a formality?

Or is there a real potential for products to be non-compliant with this criteria, warranting additional precautions / supporting data to be requested from manufacturers? For example, is it a greater concern for imported products, as opposed to North American manufactured products?

Just trying to determine what additional product research, technical specification language and formal construction submittal/quality control manufacturer documentation is legitimately warranted as a good-faith effort to address it.

SCAQMD Rule 1168 bans these chemicals, but SCAQMD Rule 1113 does not.  CDPH standard method 2010 has a limit for methylene chloride but is silent on perchloroethylene. You would have to do additional research for paints and coatings to confirm.  Their MSDS sheets should provide you the information.
