Question 1492 Deck General

The correct answer is B) sampling a harmful substance. Sampling a harmful substance is not considered a "discharge" under U.S. pollution regulations, as it does not involve the release or disposal of the substance. Discharges refer to the intentional or accidental release of pollutants, such as pumping, spilling, or leaking a harmful substance. Sampling, on the other hand, involves taking a small amount of the substance for analysis, which does not constitute a discharge. The other options (A, C, and D) are incorrect because they all involve the release or disposal of a harmful substance, which would be considered a discharge under the pollution regulations.
