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

Two primary revisions were adopted. 1. Revise the RO C 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 ca tegory for lab furniture coatings. 2. Implement the

use of low-emission cleanup solvents for surface pr eparation, 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 Po llution 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 organi c compound emissions in Ventura County. The additional

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

of ozone standards.
