Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule 

Two primary revisions were adopted. 1. Revise the ROC limit for general air-dry one-component coatings from 

2.8 pounds per gallon to 2.3 pounds per gallon. Also, create a new multi-component coating category with an 

ROC limit 2.8 pounds per gallon and eliminate the special category for lab furniture coatings. 2. Implement the 

use of low-emission cleanup solvents for surface preparation, spray gun cleaning and general purpose cleanup. 

ROC content will be limited to no more than 25 grams per liter (g/l), or 0.21 lb/gal. The effective date for these 

revisions is 90 days from the date of adoption by the Ventura County Air Pollution Control Board (July 7, 2008).

VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment 

Discussion: Revised Rule 74.12 will reduce reactive organic compound emissions in Ventura County. The additional 

reductions will help the District achieve both state and federal RFP requirements and further progress toward attainment 

of ozone standards.
