Question # 715

715. A reportable chemical is used to clean machinery once a month, every month. Activity involving this chemical would not appear to change from year to year if this is the only activity for which the chemical is used. Is it possible to have an activity ratio of 1?
Yes. It is possible that the activity ratio for a chemical equal 1 if the frequency of the activity for which it is used does not change. The activity index is the measure of an operation at a facility, a production index is the measure of the plant’s actual productivity in relation to chemical usage.
