ARCHITECTURAL COATINGS6
• Local air districts have authority
•ARB’s Suggested Control Measure (SCM)- Developed in 1977 as model rule- Updated in 1985, 1989, and 2000
• Some districts are updating SIPs with architectural coating measures
Rules
ARCHITECTURAL COATINGS7
•Before 2000, air districts’ rules wereinconsistent with the SCM
•Districts adopted rules based on 2000 SCM (20 to date)
•Rules cover 95% of CA’s population
Rules (contd.)
