From the Standard VOC Limits chart from SCAQMD, which column is the most current limit to be using? For example, if I have a "Primer, Sealer, Undercoater," and it's Ceiling Limit is stated as 350g/L, Effective Date 1/1/03 is stated as 200g/L, and Effective Date 7/1/06 is 100g/L, which is the max. VOC content that i should be judging by to be compliant for this credit?
