1 Exposure scenario titles consist of release activity followed by exposure calculation abbreviation.

2 Release activities are from engineering report's Manufacturing (Mfg), Processing (Proc) and Use release

activity labels. Multiple release activities are combined in one exposure scenario if their releases occur at

same location.

3 Exposure calculations are Acute Dose Rate (ADR), Lifetime Average Daily Dose (LADD), and

Probabilistic Dilution Model (PDM). There may be one, two, or all three exposure calculations per exposure

scenario.CC is the aquatic concentration of concern.11/27/13 Page of

4 This column displays concentration values for the 7Q10 streamflow, whi ch is defined as the average daily

streamflow of the seven consecutive days of lowest flow within a ten year period.
