Section 20.2.1.116 - SIGNIFICANT FIGURES

A. All emissions standards are deemed to have at least two significant figures, but not more than three significant figures.

B. At least five significant figures shall be retained in all intermediate calculations.

C. In calculating emissions to determine compliance with an emission standard, the following rounding off procedures shall be used:

(1) if the first digit to be discarded is less than the number five, the last digit retained shall not be changed;

(2) if the first digit discarded is greater than the number five, or if it is the number five followed by at least one digit other than the number zero, the last figure retained shall be increased by one unit; and

(3) if the first digit discarded is exactly the number five, followed only by zeros, the last digit retained shall be rounded upward if it is an odd number, but no adjustment shall be made if it is an even number.

D. The final result of the calculation shall be expressed in the units of the standard.
