G. Visible emissions from each affected unit located in an attainment area shall not exceed 10% opacity except during one six-minute period in any one hour in which visible emissions shall not exceed 20% opacity as determined by Reference Method 9. This condition applies at all times except during startup, shutdown, and malfunction.
H. Visible emissions from each affected unit located in a nonattainment area shall not exceed 5.0% opacity except during one six-minute period in any one hour in which visible emissions shall not exceed 10% opacity as determined by the Reference Method 9.
