"Six-minute (6) block average for Continuous Opacity Monitors (COM)" means a set of 36 or more readings of opacity equally spaced over a six-minute period. The six minute periods start at the top of each hour. There are 10 distinct block averages in each hour. Each six-minute block average is determined by dividing the sum of the readings by the number of readings taken in that six-minute period.
