When EPA or EDBA limits are exceeded by less than one whole number, how should the value be treated?

• A. Round down to the next whole number
• B. Round up to the next whole number
• C. Ignore the excess
• D. Halve the value

Answer: (A)

When limits are stated as whole numbers, small fractional overages are treated by rounding the measured value down to the nearest whole number. This means that if the limit is, say, 5, and you measure 5.4 (an excess of less than a full unit), you would regard it as 5 for compliance purposes. The idea is to avoid labeling a minor, potentially measurement-uncertainty-driven overage as a violation. Rounding up would unfairly penalize tiny fractions as violations, and ignoring the excess or halving the value doesn’t align with standard rounding practices for regulatory comparisons. So rounding down to the next whole number best reflects a conservative, consistent approach to determine compliance.
